The most commonly reported issue is 5.7L HEMI Exhaust Manifold Bolt Failure with 350 owner reports. Across all issues with published estimates, repair costs range from $5 to $1,800. DIY maintenance guides at au7o.io.
On the 2005-2023 Chrysler 300 5.7L HEMI V8, the 5.7L HEMI is notorious for exhaust manifold bolts breaking, especially on the passenger side. Thermal cycling causes bolts to become brittle and snap. Creates a ticking noise at cold startup that partially diminishes as engine warms but never fully goes away. Broken bolts can be extremely difficult to extract if snapped flush with the cylinder head.
Noise diminishes as engine warms but doesn't fully disappear
Visible exhaust soot around manifold flanges
Failed emissions inspection
Exhaust smell in engine bay
How to Fix
Extract broken bolts using ProMAXX drill template tool kit (PMXA200PROP) to safely extract without damaging cylinder head. Replace with upgraded Grade 8 double-ended studs and nuts instead of bolts. Apply anti-seize compound on new hardware. Consider Hooker Blackheart stainless replacement manifolds for a permanent upgrade on high-mileage vehicles.
Owner tips & cautions
TipReplace bolts with Mopar double-ended studs (6509863AA/6510141AA) and Grade 8 nuts instead of bolts - far more durable solution
TipProMAXX broken bolt repair kit (PMXA200PROP) is the safest way to extract broken bolts without damaging the cylinder head
TipUse Felpro exhaust manifold gasket set MS96692 (2005-2008) when replacing - always install new gaskets
WarningAlways apply anti-seize compound on new hardware to prevent future seizure from thermal cycling

On the 2005-2010 Chrysler 300, first-generation Chrysler 300 models suffer from extremely rapid front suspension wear including tension struts (radius arms), inner and outer tie rods, lower control arm bushings, and sway bar end links. Bushings typically worn by 45,000-60,000 miles. This is a known endemic problem across all LX-platform vehicles (300, Charger, Magnum, Challenger).
Clunking or thumping noise from front end over bumps
Loose or wandering steering
Uneven tire wear
Front end feels like it's collapsing over sharp bumps
Sway bar clunking in turns
How to Fix
Replace tension struts, lower control arm bushings, tie rod ends, and sway bar end links as a complete set. Use quality aftermarket parts from Moog. Alignment required after repair. Inspect rear suspension cradle bushings simultaneously as they often wear at the same rate.
Owner tips & cautions
TipMoog lower control arm bushing K200200 (at shock) and K200199 (at frame, RWD) are the preferred upgrades over OEM for longevity
TipOEM tension struts: driver 5180607AB, passenger 5180606AB - replace both sides together
WarningReplace all front bushings at once rather than chasing individual components - saves repeat labor costs

On the 2005-2010 Chrysler 300, a small plastic clip in the shifter mechanism breaks, causing the vehicle to become stuck in Park. Known design flaw in the first-generation LX platform vehicles. The clip is inexpensive but causes a completely disabled vehicle when it fails. Emergency brake override button near shifter can bypass the issue temporarily.
Replace broken shifter clip (Mopar 4578446AA). Accessible by removing center console trim. Keep a spare clip in the glove box. Know the location of the brake override release near the shifter for emergency bypass.
Owner tips & cautions
TipMopar shifter bushing/clip 4578446AA is the fix - costs under $10 and takes 15 minutes to replace
WarningCarry a spare clip in the glove box - this part WILL fail again eventually
TipKnow the location of the brake override release near the shifter to get out of Park in an emergency

On the 2005-2010 Chrysler 300, the dashboard pad on first-generation Chrysler 300 models warps and sinks, particularly near the driver's side defroster vent. The material deteriorates from UV exposure and heat cycling, becoming sticky or tacky in hot climates. Chrysler refused to address under warranty, stating it meets commercial standards.
Dashboard surface becoming sticky or tacky in hot climates
Warped or distorted dashboard appearance
How to Fix
Install aftermarket dash cover (DashMat is most popular) or replace entire dashboard. Park in shade and use windshield sunshade to slow deterioration. No OEM recall or fix available.
Owner tips & cautions
TipDashMat dashboard cover is the most popular and cost-effective solution at $50-$80
TipPark in shade and use windshield sunshade to dramatically slow deterioration

On the 2005-2023 Chrysler 300, the Chrysler 300 uses Chrysler's proprietary natural-vacuum leak detection hardware instead of a conventional pressure-based leak detection pump. On 2005-2006 cars this is the NVLD (Natural Vacuum Leak Detection) valve/solenoid; from 2007 onward it is the ESIM (Evaporative System Integrity Monitor), a small spring-and-diaphragm switch mounted on or next to the charcoal/vapor canister on the left underbody ahead of the fuel tank. Both work the same way: as the sealed EVAP system heats and cools, natural pressure/vacuum changes trip an internal switch the PCM reads to confirm the system is sealed. The diaphragm seal inside the NVLD/ESIM is a well-documented high-failure item — it stiffens, sticks, or loses its seal with age, so the PCM can no longer verify integrity and falsely reports a leak. The result is a check-engine light with P0456 (small leak, ~0.020 in.), P0455 (large leak), or P0457 (interpreted as loose/missing cap), even when the fuel system is actually sealed. Because the code wording points at the gas cap, this is very commonly misdiagnosed: owners and shops replace the cap (and often the purge valve and canister) repeatedly before discovering the NVLD/ESIM itself is the culprit. One 2012 300 SRT owner reported eight dealer visits — the ESIM and its seal replaced twice, plus a new filler neck, purge valve, and charcoal canister — before the leak code was resolved. The fault is an emissions/MIL issue only: it does not affect drivability or engine longevity, but it will fail an emissions/smog inspection and on some model years can disable remote start until cleared. A faint fuel-vapor smell is occasionally reported when an actual leak is present.
Check engine light / MIL on with no drivability change
Stored EVAP leak codes P0455, P0456, and/or P0457
Dashboard or message-center warning that the gas cap is loose/off even when it is tight
Repeat check-engine light after replacing the gas cap
Failed state emissions / smog inspection
Remote start disabled until the code is cleared (some model years)
Occasional faint fuel-vapor smell near the tank/filler when an actual leak is present
How to Fix
Always start with the cheapest checks: tighten the fuel cap fully (listen for clicks), inspect the cap's O-ring seal, and replace a cracked/old cap with a genuine Mopar cap, then clear the code and drive several drive cycles. If the code returns, have a shop perform an EVAP smoke test — but note the small-leak verification monitor can fail even when a smoke test passes (some hairline EVAP-line cracks only open under vacuum, sealing under the positive pressure of a smoke machine). Inspect the EVAP lines and the purge valve/solenoid for cracks. If the cap, lines, and purge valve are good, replace the NVLD valve (2005-2006) or the ESIM (2007+); the ESIM is the common Mopar service part (e.g., P/N 4861959AD), typically about $40-$60 OEM ($20-$50 aftermarket), and unbolts from the canister with a few hand tools — a DIY-friendly job. On early cars where the NVLD/ESIM is integrated and sold only with the charcoal canister assembly, expect a higher parts cost. After replacement, clear the codes and complete the EVAP drive-cycle/monitor before re-testing for emissions. Total at a shop generally runs from roughly $150 (ESIM swap with labor) up to the $417-$476 range if a full vapor/charcoal canister assembly is needed.
