On the 2017-2023 Chevrolet Bolt EV, the Bolt EV's electric cabin heater (PTC heater) can fail, leaving occupants without heat in cold weather. The heater draws significant battery power and its control module can malfunction, resulting in either no heat output or the "Service High Voltage Charging System" warning. Range is also severely impacted in cold weather due to heater power draw.
Common Symptoms
No heat output from vents in cold weather
Service High Voltage Charging System message
Significantly reduced range in winter
Heater blows cold air intermittently
Clicking noise from HVAC system
Defrost not clearing windshield effectively
How to Fix
Diagnose heater control module and PTC heater element. Replacement of the heater assembly or control module resolves the issue. Some owners use seat heaters and a heated steering wheel as a workaround to reduce cabin heater dependency and extend range.

On the 2020-2022 Chevrolet Bolt EV, for the 2020-2022 Bolt EV, GM abandoned wholesale module replacement in mid-2023 and substituted an advanced diagnostic software package (recall 21V650) that continuously monitors the pack and flags a defective module before it can go thermal. That remedy is only as good as its installation, and GM's own service records showed the reflash had not been performed correctly on a number of cars. GM therefore issued two follow-up recalls: 24V481 (66 Bolt EV) and 24V812 (88 Bolt EV). On these vehicles the car cannot identify a defective battery module needing replacement, so the owner believes they are protected and charges to 100% while the fire-risk detection is effectively dead. This is a software-remedy installation failure, distinct from the original cell defect - the pack may be perfectly sound, but the monitor that was supposed to watch it is not running.
Common Symptoms
Vehicle shows recall 21V650 as complete but 24V481 or 24V812 open on the VIN
No diagnostic alerts from the battery monitoring system even after months of driving
No warning before a battery module thermal event
Charge limit restored to 100% without the diagnostic package actually running
How to Fix
Free recall remedy, roughly one hour of dealer time. The dealer reprograms the Hybrid Powertrain Control Module 2 (HPCM2), the Battery Energy Control Module (BECM) and the Body Control Module (BCM) with the correct advanced diagnostic calibrations. Until it is confirmed installed, keep the charge target below 100% and do not leave the car charging unattended indoors. These campaigns are very small - verify by VIN rather than assuming a 2020-2022 car is affected, and confirm 21V650 itself shows as completed.
On the 2017-2023 Chevrolet Bolt EV, one of the defining Bolt EV faults: the dash throws "Propulsion Power Is Reduced", the turtle icon lights, and the car derates to a crawl - sometimes at freeway speed with no warning. GM issued a customer satisfaction bulletin in April 2018 for what it calls a battery low voltage cell condition on early Bolt EVs, where one or more cells sags below threshold and the BECM cuts power. GM stated the condition also gives the driver inaccurate state-of-charge information, so the car reports more usable energy than it actually has before it derates. GM used OnStar telematics to monitor affected cars for low cell voltage and reduced-propulsion events. There are two distinct populations: a genuine weak-cell or weak-module condition (the 2017-2019 LG-cell cars, most likely to end in module replacement), and an over-sensitive BMS calibration that throws a false alert, for which GM released updated software. Forum reports pair the message with codes P0AEE, P9BD2 and P0BDC. On 2020-2023 cars the same message more often traces to the advanced diagnostic software flagging a specific module by design.
Common Symptoms
"Propulsion Power Is Reduced" message on the driver information centre
Turtle icon illuminated and speed limited
Sudden loss of acceleration at highway speed
State of charge reading higher than actual remaining energy
Car will not charge after the fault sets
Fault does not clear on its own after a power cycle
How to Fix
Do not keep driving it - a derate at speed is a genuine hazard. Have the dealer pull the BECM/HPCM2 codes; P0AEE, P9BD2 and P0BDC on this platform point at high-voltage battery cell and pack voltage faults, and the diagnosis is a cell-voltage balance read of the pack. If the older over-sensitive calibration is present, the fix is a free BECM/HPCM2 software update. If a genuine weak cell or module is found, the module - or on recall-eligible cars the full pack - is replaced under the high-voltage battery warranty (8 years/100,000 miles) at no cost. GM's interim advice was to keep the pack above 30% state of charge to reduce the chance of a derate. Verify all outstanding battery campaigns are closed at the same time, since the diagnostic software recall deliberately triggers the same message when it finds a bad module.
On the 2017-2022 Chevrolet Bolt EV, all 2017-2022 Bolt EV and 2022 Bolt EUV vehicles were subject to a massive recall for battery fire risk. LG Energy Solution manufactured battery cells with two simultaneous defects — a torn anode tab and a folded separator — that could cause an internal short circuit and thermal runaway (fire) during charging, particularly when the battery was charged to 100%. Multiple Bolt EVs caught fire while parked and charging, leading GM to halt sales and production temporarily. GM ultimately replaced every battery module in every affected vehicle at no cost.
Burning smell or smoke from under vehicle (EMERGENCY: call 911)
How to Fix
Check your VIN at my.chevrolet.com/recalls or NHTSA.gov. All affected Bolts receive a FREE complete battery module replacement with updated LG cells that do not have the manufacturing defects. The replacement also includes updated battery management software and an extended 8-year/100,000-mile warranty on the new battery. If you have not had the recall completed, schedule it immediately at any Chevrolet dealer. Until the recall is completed, GM advises: do not charge above 90%, do not deplete below 70 miles of range, do not charge indoors overnight, and park outside away from structures.
On the 2017-2023 Chevrolet Bolt EV, the Bolt EV infotainment system frequently freezes, goes to a black screen, or reboots while driving. The touchscreen becomes unresponsive, losing access to climate controls, navigation, and the rearview camera. The issue affects all model years but is most common on 2017-2020 models.
Common Symptoms
Touchscreen goes black while driving
Infotainment reboots on its own
Loss of rearview camera display
Climate controls unresponsive
Bluetooth connectivity drops repeatedly
System extremely slow to respond to inputs
How to Fix
Perform a hard reset by holding the power/volume knob for 10+ seconds. Software updates from the dealer may temporarily help. Persistent issues may require infotainment module replacement under warranty or Chevrolet goodwill program.

On the 2017-2023 Chevrolet Bolt EV, the Bolt EV is never fully powered down; modules continue to wake for telematics, charge scheduling and pack maintenance, and the DC-DC converter is supposed to top the 12V accessory battery from the traction pack on a periodic wake cycle. Owners across chevybolt.org and mychevybolt.com report that cycle failing or being outrun by parasitic draw, leaving a flat 12V after as little as three days parked. Reports cluster on cars that sat on dealer lots for months (which permanently degrades the 12V), on cars whose top-up algorithm becomes less aggressive when traction pack state of charge is low, and on cars with a genuine parasitic draw where the drain happens overnight but never during the day. The consequence is worse than on a gas car: with a dead 12V the Bolt will not power up, will not accept a charge, and the charge port latch stays locked with the cable trapped in the port. Owners report repeat failures - one 2021 car died five times, another killed a brand new battery within a month.
Car completely dead - no dash, no power button response, no door unlock
Dead 12V battery after only a few days parked
Battery drains overnight but not while parked during the day
Cannot start a charge session even though the traction pack has charge
Charge cable locked in the port and will not release
Repeat 12V battery failures within months of replacement
Multiple module warning lights after a jump start
How to Fix
First confirm the 12V battery itself: a lot-aged or repeatedly deep-cycled AGM must be replaced, not merely recharged. Then measure parasitic draw with the car asleep for a full 45-60 minute module shutdown period; a healthy Bolt settles to a low milliamp draw. Persistent drains have been traced to modules failing to sleep and to a DC-DC/APM top-up cycle that is not running - both warrant dealer diagnosis, and the charging and battery control modules fall under the EV component warranty. Practical mitigation: keep traction pack state of charge above roughly 30%, plug in when parked long-term, and use a 12V maintainer if the car sits for weeks. Learn the emergency manual charge-port release before you need it.
What you need to diagnose it
The fix here starts with a test, not a part — which repair you need depends on what the test finds.At least one code uses a manufacturer-specific format. No scanner recommendation is shown because family-level coverage cannot prove it can read that code.

Testing and isolating the fault is DIY work. Replacing or reprogramming a control module is not — most are VIN-programmed, so a new one does nothing until a shop codes it to your car. Check for an open recall or service bulletin before buying anything.
On the 2017-2023 Chevrolet Bolt EV, the Bolt EV charge port uses a motorised locking pawl that holds the J1772 connector in place while charging. Owners report the latch sticking in two opposite failure modes. Stuck extended, the metal latch physically blocks the top prong of the charge connector so the cable will not enter the port at all. Stuck locked, the connector cannot be withdrawn and the car holds the owner's cable - or a public station's cable - hostage. Contributing causes reported by owners include a weak or dead 12V battery (the latch actuator loses the power to retract), water ingress into the connector handle that freezes the mechanism in cold weather, and physical breakage of the fragile plastic latch tab after the connector is dropped. The 12V link makes this compound with the parasitic-drain issue: a car dead on 12V is also a car with a cable locked into it.
Common Symptoms
Charge cable will not insert - silver latch tab blocking the connector
Charge cable locked into the port and cannot be unplugged
Latch mechanism stuck or silent when unlocking
Problem worse in freezing or wet weather
Latch will not release when the 12V battery is flat
Broken plastic latch tab on the connector
How to Fix
For a trapped cable, first try disconnecting the 12V battery for a minute or more and reconnecting - this is the fix most frequently confirmed by owners, and it works because it drops power to the locking pawl. On later cars, use the emergency manual charge-port release. If the mechanism is frozen, warm the connector handle with a hair dryer until the ice releases. If the latch is physically broken or the actuator has failed, the charge port assembly is replaced; check first whether it falls under the EV component warranty as part of the charging system. Address any underlying 12V weakness, because a marginal 12V will keep causing latch faults after the port itself is repaired.
On the 2017-2023 Chevrolet Bolt EV, the Bolt EV 60/65 kWh battery pack experiences capacity degradation over time, reducing the vehicle range from the original EPA rating. Early 2017-2018 models with the original LG battery showed faster degradation, losing 10-15% capacity in the first 50,000 miles. Vehicles that received the recall battery replacement generally show slower degradation rates. Factors that accelerate degradation include frequent DC fast charging, regularly charging to 100%, leaving the battery at full charge for extended periods, and exposure to extreme heat. The battery management system (BMS) also recalibrates periodically, which can cause sudden apparent range drops.
GOM (Guess-O-Meter) range estimate increasingly inaccurate
How to Fix
Use the Hilltop Reserve or Target Charge Level feature to limit charging to 80-90% for daily driving — this significantly reduces degradation. Avoid DC fast charging for daily use; save it for road trips. The Bolt EV battery has an 8-year/100,000-mile warranty covering degradation below 60% of original capacity. Vehicles that received the recall battery get a new warranty starting from the replacement date. Monitor battery capacity using the Energy screen or a Torque Pro app with an OBD-II adapter to track state of health over time.
On the 2017-2023 Chevrolet Bolt EV, after the battery recall replacement, many Bolt EV owners report significantly reduced DC fast charging (DCFC) speeds. Where the pre-recall Bolt could sustain 50+ kW at a CCS fast charger, post-recall vehicles often cap at 30-40 kW. GM updated the battery management software to be more conservative with thermal management, limiting charging power to protect the new battery from the conditions that caused the original fire risk. The reduced charging speed adds 15-30 minutes to fast charging sessions on road trips. Cold weather further reduces charging speeds.
Common Symptoms
DC fast charging peaks at 30-40 kW instead of 50+ kW
Charging sessions take significantly longer than before recall
Charging speed drops rapidly above 50% SOC
Charging extremely slow in cold weather
Battery temperature limiting message during fast charge
How to Fix
There is currently no fix — the reduced charging speed is an intentional software limitation by GM to protect the replacement battery. Precondition the battery before arriving at a fast charger by setting navigation to a DC fast charge station (the Bolt will warm the battery en route, improving charging speed by 10-20%). Avoid fast charging when the battery is below 20% or above 80% for best charging rates. Some aftermarket tools can monitor BMS temperature limits, but modifying the charging software voids the battery warranty.

On the 2017-2023 Chevrolet Bolt EV, the 10.2-inch infotainment touchscreen in the Bolt EV develops ghost touch inputs, screen flickering, unresponsive areas, and random screen blackouts. The screen registers phantom touches that change radio stations, adjust climate controls, or activate features without driver input. The issue is caused by a failing digitizer layer in the touchscreen or a loose ribbon cable connection behind the display. Hot weather and direct sunlight on the screen exacerbate the ghosting behavior. The issue affects both the original infotainment system and the updated system in 2020+ models.
Perform a system reset by holding the Home and Fast Forward buttons simultaneously for 10 seconds. If ghosting persists, the display panel needs replacement ($500-$1,000 for parts, $200-$400 labor). A loose ribbon cable behind the display can sometimes be reseated without replacing the entire screen — ask the technician to check this first ($100-$200 diagnostic). Some owners have resolved minor ghosting by installing a tempered glass screen protector, which insulates the digitizer from temperature-induced phantom touches.
On the 2017-2023 Chevrolet Bolt EV, on 2017-2023 Bolt EV, the front seat belt pretensioners vent hot exhaust gas into the lower B-pillar area when they deploy in a crash. GM found the exhaust can ignite the carpet fibers next to the pretensioner, starting a post-crash fire. The defect was identified after a 2018 Bolt EV in Korea burned with the fire appearing to originate in the right-side lower B-pillar. GM issued recall 22V930 (GM numbers N222383790 / N222383791) covering the full 2017-2023 Bolt EV run. A follow-up recall, 23V845 (GM N232421970 / N232421971), was issued in December 2023 for roughly 6,771 vehicles because dealers had not actually performed the 22V930 remedy procedure on 2020-2023 cars that were marked as repaired. This is the largest non-battery safety campaign on the nameplate and it is frequently still open on used Bolts because of the botched first round.
Common Symptoms
No symptom before a crash - the defect is latent
Post-crash fire originating at the lower B-pillar / floor carpet
Burned or scorched carpet near the front seat belt lower anchor
Recall notice showing 22V930 or 23V845 open on the VIN
How to Fix
Free recall remedy. Dealers inspect both front seat belt pretensioners and install metal heat-shielding foil on the carpet adjacent to the pretensioner exhaust port; some vehicles additionally require a pretensioner cover. Because the first campaign was performed incorrectly on thousands of cars, run the VIN through NHTSA and GM even if the service history says 22V930 was completed - if the car is in the 23V845 population it needs the work redone at no charge.
On the 2020 Chevrolet Bolt EV, a single manufacturing lot of front left brake calipers fitted to 2020 Bolt EVs was improperly cast. Under a high-pressure braking event the caliper body can fracture and dump brake fluid, causing a sudden loss of hydraulic pressure on that corner and badly reduced braking performance. The defect was caught by the caliper supplier during a high-pressure leak test rather than by field failures, and GM recalled 464 vehicles under NHTSA 20V808 (GM number N202321400). This matters disproportionately on the Bolt because heavy one-pedal regen use means the friction brakes are loaded hard only occasionally - exactly the panic-stop scenario in which the caliper is stressed enough to break.
Common Symptoms
Long or soft brake pedal after a hard stop
Sudden loss of braking / pedal goes toward the floor
Brake fluid leak at the front left wheel
Brake warning light and low brake fluid level
Vehicle pulls right under braking
How to Fix
Free recall remedy. The dealer reads the casting lot number stamped on the front left caliper and replaces the caliper if it comes from the suspect lot. Only 2020 model year cars are in scope and the population is small, so verify by VIN rather than assuming. If a caliper has already fractured, the out-of-recall repair is a caliper, pads and a full brake fluid flush and bleed.
On the 2017-2023 Chevrolet Bolt EV, the front electric drive motor in the Bolt EV develops a whining, humming, or grinding noise from the motor bearings as mileage increases. The single-speed reduction gear unit contains bearings that wear over time, particularly in vehicles driven frequently at highway speeds where the motor spins at high RPM. The noise is speed-dependent (gets louder with speed) and is most noticeable with the radio off and windows up. The Bolt is otherwise a quiet vehicle, making the bearing noise particularly noticeable. Some owners describe it as a "gear whine" that develops after 50,000-80,000 miles.
Common Symptoms
Whining noise that increases with vehicle speed
Humming or buzzing from front of vehicle
Grinding noise at highway speeds
Noise louder during acceleration than coasting
Vibration felt through floorboard at speed
How to Fix
The drive unit bearings are not serviceable individually — the entire drive unit assembly must be replaced or rebuilt. A new drive unit from GM costs $3,000-$5,000 plus $500-$1,000 labor. Some EV specialty shops can rebuild the drive unit with new bearings for $1,500-$2,500. The Bolt EV powertrain warranty covers the drive unit for 8 years/100,000 miles — have the noise documented at a dealer while under warranty. Changing the drive unit fluid (Dexron HP) at 75,000-mile intervals may help prevent premature bearing wear.
