    Some 2022-2023 Frontier trucks equipped with the 9-speed automatic were recalled because the transmission parking pawl may not engage when the shifter is placed in Park. Owners reported vehicles rolling after being parked, sometimes with no warning other than the truck not being fully secured. This is a direct safety issue because it can lead to unintended vehicle movement.

    Common Symptoms

    • Vehicle rolls after being shifted into Park
    • Truck does not stay stationary on an incline
    • Need to rely on parking brake to prevent movement
    • Intermittent improper Park engagement

    How to Fix

    Verify recall completion status by VIN and inspect whether the transmission parking pawl remedy has already been performed. Dealers replace or repair the affected transmission parking mechanism per Nissan recall procedure and confirm proper Park engagement. Until repaired, owners are advised to use the parking brake every time the vehicle is parked.

    Owner tips & cautions

    • TipCheck VIN for open recall status before purchase and confirm dealer paperwork shows the parking pawl remedy was completed.

    If you drive a 2025 or 2026 Frontier, Nissan has recalled the truck over its door strikers. The strikers may have been welded improperly when the truck was built, and a bad weld can let the striker break — the door then has nothing holding it shut and can swing open with the truck in motion. Nissan reports the condition as a failure to meet Federal Motor Vehicle Safety Standard 206, which governs door locks and door retention components. NHTSA lists 26,432 units for the campaign as a whole, a figure spanning every model Nissan included, not a Frontier-specific count. Nissan tracks the campaign internally as PD185 and PMA61.

    Common Symptoms

    • A door coming open unexpectedly while driving
    • Broken door striker

    How to Fix

    Dealers replace the door strikers at no cost to the owner. Nissan mailed owner notification letters on March 17, 2026, and VIN lookup for this campaign went live at NHTSA on January 28, 2026. Run your Frontier's VIN through nhtsa.gov/recalls to confirm it is covered, then schedule the free striker replacement with a Nissan dealer. Questions can go to Nissan customer service at 800-647-7261 under recall PD185/PMA61.

    The resin emblem on the driver's air bag module cover may have reduced durability, so its posts can crack over time and the emblem and retainer can detach when the air bag deploys. A detached emblem or retainer can become a projectile, increasing the risk of injury; Nissan reports there is no warning beforehand. Applies to: 2008-2011 Nissan Frontier (D40) built September 13, 2007 to December 23, 2010 with the affected Autoliv driver air bag assembly (Part 573, Vehicle 2); the same recall covers Titan, Xterra, Pathfinder, Armada and Quest. Nissan's current dealer bulletin NTB23-081B (campaigns PC945 and PC948) lists 2005-2013 Frontier (D40). Only a Nissan dealer can confirm by VIN whether a truck is included and whether the work has been done.

    How to Fix

    Have a Nissan dealer check the VIN for open recall 23V067 (Nissan campaigns PC945/PC948). The dealer inspects the driver air bag cover and, if necessary, replaces it, at no charge for parts or labor. Air bag work is dealer-only.

    In areas that use heavy road salt, a mixture of snow, water and salt can enter the front crash zone sensor housing during continuous driving on salted roads. The sensor may rust internally and interrupt its signal, lighting the red air bag warning light; this could result in the driver and passenger front air bags not deploying in a crash. Applies to: 2005-2009 Frontier (D40) built from June 2004 to November 19, 2008, so only 2009 trucks built before that date; trucks built later have a countermeasure sensor. The recall replacement applied to trucks registered in Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania, Delaware, Maryland, West Virginia, Ohio, Indiana, Michigan, Illinois, Wisconsin, Minnesota, Iowa, Missouri and the District of Columbia when the campaign launched. Owners in other states instead got a 10-year sensor warranty extension for corrosion, which has now expired for these model years. The same recall covers Pathfinder and Xterra. Only a Nissan dealer can confirm by VIN.

    How to Fix

    If the red air bag warning light is on, have a Nissan dealer check the VIN for open recall 08V690 (Nissan campaign R0807). For eligible trucks the dealer replaces the front crash zone sensor with a countermeasure sensor. Air bag system work is dealer-only.

    The driver air bag inflator may have been assembled with gaskets missing, which could let moisture enter and build up over time. Over a long period this can reduce pressure inside the inflator, so the air bag may deploy with reduced force and not protect the driver as intended, increasing the risk of injury. Nissan reports there is no warning beforehand. Applies to: Only 2024 Nissan Frontier (D41) trucks fitted with the affected driver air bag module; the Part 573 report lists Frontier production on October 11, 2023 only. The same recall covers some 2023 Rogue, 2024 Pathfinder and Titan, 2023-2024 Sentra, Versa and Kicks and some INFINITI models. Only a Nissan dealer can confirm by VIN whether a truck is included and whether the repair has been done.

    How to Fix

    Have a Nissan dealer check the VIN for open recall 24V154 (Nissan campaign PD103). Dealers replace the front driver air bag assembly with a new one, free of charge for parts and labor. Air bag work is dealer-only.

    Nissan recalled roughly 4,200 2023 Frontier and Titan trucks because the tires may have a tear in the inner bead that can cause a rapid loss of tire pressure. The cause was on the assembly line rather than in the tire itself: a tire mounter boot had been replaced with an incorrectly shaped part that could contact the inner bead as the tire was mounted onto the wheel, nicking or tearing it. A tear in the bead area is not visible from outside the wheel and can let go suddenly at speed, so the risk is a sudden deflation or blowout rather than a slow leak. The campaign is split into two parts - PC973 covering the four road tires and PC974 covering the spare - because the spare was mounted on the same equipment. Affected trucks are 2023 model year only and the population is small, so VIN lookup is essential.

    Common Symptoms

    • Rapid loss of tire pressure
    • Repeated low tire pressure warnings
    • Sudden deflation or blowout at speed
    • No visible external tire damage

    How to Fix

    Free recall remedy. Dealers replace all four road tires under Nissan campaign PC973, and inspect and replace the spare tire assembly as necessary under PC974, at no charge. Verify a specific truck by VIN at nhtsa.gov/recalls or through a Nissan dealer - the defect is invisible on a visual walk-around and a TPMS warning may be the only advance notice. If an affected truck has already had its tires replaced at the owner's expense, Nissan reimbursement provisions for recall repairs performed before the campaign may apply, so keep the receipts.

    Nissan recalled certain 2022 Frontier (D41) trucks because the mounting bolts for the left-rear seat belt buckle bracket may have been cross-threaded during assembly due to a tooling error, leaving them improperly tightened. A loose or damaged anchorage can break in a crash, causing a loss of seat belt restraint for that occupant. The vehicles do not comply with Federal Motor Vehicle Safety Standards 207 (Seating Systems), 209 (Seat Belt Assemblies) and 210 (Seat Belt Assembly Anchorages). The practical warning sign owners can notice is a rattle from the rear seat area caused by the loose bolt. Owner notification letters went out on January 27, 2022. This is a manufacturing/assembly defect confined to a narrow build window, not a design fault of the seat belt system.

    Common Symptoms

    • Rattling noise from the left-rear seat area while driving
    • Loose left-rear seat belt buckle bracket
    • Seat belt buckle bracket movement when tugged

    How to Fix

    Free recall remedy. Dealers replace the bolts on the left-rear seat belt buckle bracket and repair any damaged threads as necessary at no charge under NHTSA campaign 21V958000, Nissan campaign PC856. Check whether a specific truck is affected by entering the VIN at nhtsa.gov/recalls or by calling Nissan customer service at 1-800-867-7669; the remedy has no expiration for safety recalls. If a rear-seat rattle is present on a 2022 Frontier, have the anchorage inspected rather than chasing trim noise.

    First-generation Frontiers fitted with the 3.3L V6 - the naturally aspirated VG33E and the supercharged VG33ER in the 2001-2004 Frontier SC - use a rubber timing belt, not the chain found on the later 4.0L VQ40DE. This is the single most consequential difference between the two V6s and the most common way a surviving first-gen Frontier is written off. The VG33E is an interference design: when the belt lets go the pistons strike the open valves, bending them and often damaging pistons and heads, which on a truck of this age exceeds its value. The belt usually fails without warning, though a high-pitched squeal or persistent ticking from the front of the engine can indicate a worn belt or a failing tensioner pulley. The service interval is 105,000 miles or seven years, and the age half of that interval is what catches out low-mileage trucks - a 20-year-old belt with 60,000 miles on it is still a failed belt. Forum reports also single out the water pump (driven by the belt) and the tensioner pulley as failures, including tensioner pulley failures shortly after a belt job done without replacing it.

    Common Symptoms

    • Sudden no-start after the engine dies while driving
    • Engine cranks but will not start and has no compression
    • High-pitched squeal or ticking from the front of the engine
    • Coolant leak from the water pump behind the timing cover
    • Rattle from a failing tensioner pulley

    How to Fix

    Treat as scheduled maintenance and replace the belt, water pump, tensioning components, seals and drive belts as applicable. A broken belt requires compression/leak-down testing before parts are ordered.

    Owners discuss low oil pressure at warm idle on VQ40DE engines and suspect the rear timing-cover oil-gallery seals. The available accounts do not establish that this is the cause on every truck. Applies to: Second-generation Frontier 4.0L VQ40DE context. The linked discussions do not establish a universal defect or a year-specific failure rate for the representative 2009 vehicle.

    Common Symptoms

    • Owner-reported low oil pressure at warm idle

    How to Fix

    Have a qualified technician diagnose the oil-pressure concern before ordering a sender, pump, cover or gasket. The suspected location in an owner discussion is not a confirmed repair for your vehicle.

    A high-frequency buzzing or whining noise can come from the secondary timing chain system, rising in pitch with engine speed. Applies to: 2005-2010 Frontier (D40) with the VQ40 4.0L V6; the bulletin also covers 2005-2010 Xterra and Pathfinder with the VQ40. It does not cover 2011-2019 Frontiers or the 2.5L four-cylinder.

    How to Fix

    If a Nissan technician confirms the noise comes from the secondary chains and rises with engine speed, bulletin NTB09-128a specifies replacing both secondary timing chains and both secondary chain tensioner shoes and changing the engine oil and filter. If the noise does not rise with engine speed, the bulletin says the timing chains may not be the cause. Normal warranty rules apply; this is not a recall or a promise of free repair.

    A common first-gen Frontier issue is broken exhaust manifold studs, especially on the VG33E/VG33ER V6. Heat cycling warps the manifold and stresses the studs until one or more snap, creating a ticking exhaust leak that is loudest on cold start. Owners often mistake it for valvetrain noise, but the sound usually fades somewhat as the manifold heats up and expands.

    Common Symptoms

    • ticking noise on cold start
    • exhaust smell in engine bay
    • louder under acceleration
    • possible oxygen sensor or lean codes
    • reduced cabin comfort from exhaust odor

    How to Fix

    Diagnosis involves listening for a cold-start tick at the manifold, checking for soot marks, and inspecting for missing or broken studs. Proper repair usually means removing the manifold, extracting broken studs, resurfacing or replacing warped manifolds, and installing updated hardware and gaskets; simply tightening remaining fasteners rarely lasts.

    Nissan's 10V517000 recall reaches the 2005 and 2006 Frontier pickup. At issue is the ECM relay contained in the Frontier's Intelligent Power Distribution Module assembly. The relay's diode uses a silicon molding to reduce electrical current noise, but Nissan found the relay may allow silicon vapor to form; as silicon evaporates from that molding, arcing deposits silicon oxide on the relay contact. According to Nissan, this can cause the engine to stall — the reason the campaign was filed as a safety recall rather than a service bulletin. Note that the 747,480 units listed apply to the campaign as a whole, which spans several Nissan and Infiniti models.

    Common Symptoms

    • Engine stalling

    How to Fix

    Take the truck to a Nissan dealer, where the ECM relay inside the IPDM assembly is replaced free of charge. The recall began December 6, 2010. Before scheduling, enter your Frontier's VIN at nhtsa.gov/recalls — that will tell you whether the relay replacement is still outstanding on your specific truck. Nissan customer service: 1-800-647-7261.

    A well-documented failure on first-generation Frontier V6 trucks is the distributor assembly, especially the internal cam/crank angle sensor and bearing wear inside the distributor. Owners report intermittent bucking, random stalling, hard starts, and eventual crank-no-start, often after the engine warms up. Nissan issued service information for distributor-related drivability faults, and owner complaint patterns are consistent across Frontier and related Xterra applications using the VG33E/VG33ER.

    Common Symptoms

    • engine stalls while driving
    • crank but no start
    • hard hot restart
    • intermittent misfire or bucking
    • tachometer drops suddenly
    • check engine light

    How to Fix

    Diagnosis usually includes checking for loss of spark/injector pulse, monitoring cam/crank signal, and inspecting distributor shaft play or oil contamination. In most cases the fix is replacement of the complete distributor assembly rather than only the cap/rotor, followed by base timing verification where applicable and inspection of plugs/wires if misfire damage occurred.

    Owners of the new-generation Frontier have reported intermittent no-start events, extended crank, or occasional stalling tied to control-module logic, battery state sensitivity, or software calibration issues. Complaints commonly describe the truck acting like a weak battery or failing to restart normally despite the battery testing good. Nissan has issued service information and software-related fixes for some starting and drivability complaints on this platform.

    Common Symptoms

    • Intermittent no-start
    • Extended cranking
    • Truck starts after multiple attempts
    • Random stall or restart issue
    • Battery tests good but symptoms persist

    How to Fix

    Begin with battery load testing, charging-system verification, and a scan for stored or pending codes in the ECM, BCM, and IPDM. If hardware checks out, dealers typically look for applicable ECM/TCM/BCM software updates and reprogram as needed. Poor battery condition or loose grounds should be corrected before module updates are performed.

    Owner tips & cautions

    • TipHave the battery tested with a real load tester, not just voltage checked; many owners found weak OE batteries caused confusing electronic symptoms.

    A 2005 Frontier owner reports the five-speed automatic not shifting into higher gears after a period parked. The owner reports that a speed-sensor replacement did not help and that a later used-transmission replacement resolved the complaint. This does not establish which internal part was faulty. Applies to: D40 Frontier with the RE5R05A five-speed automatic only. The 2005 account is earlier same-generation context for the 2009 card; another cited discussion concerns a 2007 truck. Not a nine-speed or manual transmission.

    Common Symptoms

    • Owner-reported failure to upshift

    How to Fix

    Have a Nissan transmission technician diagnose the shifting complaint before ordering parts. The used-transmission outcome is one owner’s report, not a fitment recommendation or the prescribed fix.

    The nine-speed automatic introduced on the 2020 Frontier (carried into the fully redesigned 2022 D41) draws a large and consistent body of complaints about drivability rather than hard failure: a lag or hesitation from a stop before the truck moves, a jerk or lurch as the transmission decides on a gear, shift shock during light-throttle upshifts, and a distinct hard downshift when decelerating to a stop from moderate speed. Owners describe it as the transmission not knowing what gear it wants. Nissan addressed it through calibration and hardware service bulletins rather than a recall - NTB20-077 covers valve body replacement, NTB21-028 covers delayed acceleration, NTB21-073 covers hesitation and shift shock on 2020-2021 Frontier, and NTB21-086 covers A/T warning lamp illumination. A consumer class action naming the nine-speed in Frontier and Titan trucks has also been filed. This is a separate concern from the parking pawl rollaway recall, which affects the same transmission but is a distinct park-engagement defect.

    Common Symptoms

    • Hesitation or lag pulling away from a stop
    • Jerk or lurch during low-speed shifts
    • Hard downshift when slowing to a stop
    • Noise when shifting
    • Delayed acceleration when the throttle is applied

    How to Fix

    Follow Nissan TSB diagnosis and perform the specified TCM reprogramming; if the software procedure does not resolve the condition, follow the later bulletin's valve-body/warranty path. A retail part link would prematurely send the reader to hardware.

    Owners report frame rust on second-generation Frontiers. A 2011 owner reports rear-frame perforation; a discussion about a 2016 King Cab describes rust that replies judged mainly superficial. These reports do not establish how often structural damage occurs. Applies to: Second-generation D40 Frontier context; the cited accounts concern 2011 and 2016 trucks, not a confirmed diagnosis on the representative 2009 truck.

    On a small percentage of trucks, an internal crack can develop in the automatic-transmission oil cooler tube inside the radiator, letting engine coolant leak internally. Nissan's extension covered damage this leak caused to other components, including the transmission. Applies to: All 2005-2010 Frontier (D40) with an automatic transmission; the same notice covers 2005-2010 Pathfinder and Xterra. Manual-transmission trucks are not included.

    How to Fix

    Nissan's 2012 notice extended radiator coverage to 10 years/100,000 miles, whichever came first, with customer co-pays after 8 years/80,000 miles. For these model years the 10-year limit has passed, so the extension has expired. If coolant or transmission fluid looks contaminated, have a technician inspect the radiator and the transmission. Normal warranty rules apply; this is not a recall.

    Many owners report recurring front brake pulsation on first-generation Frontiers, often traced to rotor thickness variation, heat spotting, or uneven pad deposits. The symptom is a steering wheel shake or pedal pulsation during moderate highway-speed braking, sometimes returning not long after a basic pad-and-rotor job. Trucks used for towing, hauling, or with neglected caliper slide maintenance seem especially prone.

    Common Symptoms

    • brake pedal pulsation
    • steering wheel shake while braking
    • front-end vibration at highway speeds when slowing
    • reduced braking smoothness
    • uneven pad wear

    How to Fix

    Diagnosis should verify rotor runout, thickness variation, pad condition, and free movement of caliper slides and pistons. The best repair is quality rotors and pads, proper hub cleaning before installation, servicing or replacing sticky calipers/hardware, and correct wheel torque to prevent repeat distortion.

    Owners of 2011 Frontiers report ABS, SLIP and VDC OFF warnings together. Other reports discuss different possible causes. The warnings alone do not confirm wheel-speed-sensor corrosion or a failed sensor. Applies to: Second-generation D40 Frontier context. The named accounts concern 2011 PRO-4X and SV 4x4 trucks, not a diagnosed fault on the representative 2009 truck.

    Common Symptoms

    • Owner-reported ABS, SLIP and VDC OFF warnings

    How to Fix

    Have a qualified technician diagnose the brake and stability-system warnings with appropriate equipment. A stored code identifies a diagnostic starting point, not proof that a replacement sensor will fix the concern.

    Multiple owners of the current Frontier have reported a persistent rear-end whine or humming noise, often most noticeable between roughly 45 and 75 mph under light throttle or coast-down. The sound is commonly traced to ring-and-pinion setup, carrier bearings, or axle-related drivetrain noise rather than tires. Some trucks received differential replacement or gear setup work under warranty.

    Common Symptoms

    • Whine from rear of truck
    • Humming noise at highway speed
    • Noise changes on acceleration or deceleration
    • Driveline noise despite normal shifting

    How to Fix

    Road-test the truck to isolate whether the noise changes with throttle input, speed, or 2WD/4WD mode, then inspect differential fluid condition and backlash/contact pattern. Dealers may replace the differential assembly, bearings, or reset gear mesh depending on findings. Rule out tire cupping before condemning the axle.

    Owner tips & cautions

    • TipCheck for metallic debris in the differential fluid if the truck is out of warranty and the noise is worsening.

    The evaporative emissions system on these trucks commonly develops faults from a sticking vent control valve, saturated charcoal canister, cracked hoses, or rust/dirt intrusion near the rear-mounted canister. Owners frequently report persistent check-engine lights and failed emissions inspections even though the truck otherwise drives normally. Nissan published EVAP-related service bulletins for leak and vent valve diagnosis on Frontier/Xterra-era trucks.

    Common Symptoms

    • check engine light
    • failed emissions test
    • fuel smell near rear of truck
    • no drivability symptoms
    • intermittent EVAP leak code

    How to Fix

    Diagnosis should include smoke testing the EVAP system, checking the vent control valve operation, inspecting canister hoses and purge lines, and verifying the gas cap seals properly. Repairs range from replacing the vent valve or damaged hoses to replacing the charcoal canister assembly if fuel saturation or contamination is present, then clearing codes and completing a drive cycle.

    A common owner complaint on the current Frontier is the center infotainment unit freezing, rebooting, losing audio, or dropping Apple CarPlay/Android Auto connections. Reports span multiple trims and years, especially on trucks with frequent smartphone integration use. The issue is usually software-related, though some owners also report sensitivity to certain USB cables or ports.

    Common Symptoms

    • Screen freezes
    • Head unit reboots
    • Apple CarPlay disconnects
    • Android Auto disconnects
    • No audio or delayed audio
    • Backup camera image lag

    How to Fix

    Confirm whether the head unit has the latest software and perform any Nissan infotainment updates or resets. Test with a known-good OEM or high-quality USB cable and inspect the USB port for looseness or contamination. If software updates do not resolve the problem, dealers may replace the head unit or USB hub under warranty.

    Owner tips & cautions

    • TipUse a short, high-quality data cable; many owners report cheap or worn cables make CarPlay/Android Auto instability worse.

    Owners of first-generation Frontiers frequently report slow, crooked, or inoperative power windows, especially on the driver side. The usual causes are worn regulator cables/plastic guides, tired motors, or dry window channels that overload the mechanism. Failures are common enough in owner forums and complaint databases to be considered a recurring age-related problem on this generation.

    Common Symptoms

    • window moves slowly
    • window falls into door
    • clicking from inside door
    • window tilts while moving
    • window stops midway

    How to Fix

    Diagnosis should confirm whether the switch is sending power and whether the motor is binding or the regulator is physically broken. The durable fix is replacement of the regulator assembly, often together with the motor if operation is weak, plus lubricating the window tracks and checking the glass alignment to reduce future strain.
