Engine And Engine Cooling Problems of Chevrolet Bolt Ev - part 1

While driving at approximately 45 mph, the regenerative braking feature of the vehicle suddenly failed, and also generated a master caution light on the dashboard display. This is the second time this has happened while driving and resulted in a sudden, alarming change in vehicle dynamics. Regenerative braking is the normal operation regime of the vehicle, with the traditional mechanical-hydraulic brake pedal available for added braking, as demonstrated by the Chevrolet dealership during a test drive and confirmed with the vehicle manual. Furthermore, the vehicle will no longer shut itself off and could pose a fire risk when stored in a garage, parking deck, other vehicles, etc. These issues happened in November 2024. The car was returned to the dealer for warranty repair. Even after extensive repairs to the electrical system, the car has repeated the alarming failure mid-drive. This indicates that there is a serious problem with the electronic and poses a serious safety risk.

I am reporting a safety issue involving the high-voltage battery system of my vehicle. Vehicle: 2017 Chevrolet Bolt Ev VIN: 1g1fx6s07h4137617 mileage: 87,125 miles the vehicle has generated a p302f diagnostic trouble code, which indicates high-voltage battery cell imbalance. This condition may pose a safety risk related to battery performance and thermal stability. The authorized Chevrolet dealership has refused to diagnose the issue under warranty unless I pre-authorize a $600 diagnostic fee. The vehicle is covered under an active gm buyback warranty and a 10-year / 100,000-mile battery warranty due to a recall battery replacement. Due to the safety implications of a high-voltage battery fault, I believe refusal to diagnose the issue under warranty may pose a risk and warrants review. I am submitting this complaint to document the issue and request investigation. Thank you.

This car several times while driving has shaken and then shifted into neutral. I have had to pull the car off to the side of the road during normal vehicle operation. The car will then not shift into drive. There is a warning sign "conditions not correct for shift. " the first incident was March 2023. The vehicle was towed to a Chevrolet dealer and the power inverter module was replaced under warranty. This next occurred in December 2024. The vehicle was towed to a dealer again and reprogrammed. The cost was $400. The vehicle was fine for two months and about 1,000 miles when it happened again in March 2025. This time the dealer states that the engine harness needs to be replaced for about $1,500 (not covered under warranty). These incidents all occur while driving the vehicle (it has happened while approaching an intersection and once while going through an intersection).

On January 8, 2025 the battery in my car began to fail and had a message in the display to take it to my dealer. I drove it to the nearest dealer on January 10, 2025, about 10 miles (billion automotive in iowa city. ) while driving the power steering and braking began to fail. The dealer said that gm would need to replace the battery. It has been at the dealer for 2 months, and I was told today that it will be at least another 2 months before gm will replace the battery. The car is well under warranty.

Twice now within three months while I was backing up as I was parking the car parallel to the curb, the car suddenly accelerated at a much faster pace and projected the car backwards. Luckily no property or individuals were hurt. It would appear that the accelerator or speed control failed at the lower speeds required when backing up to parallel park. I saw no warning lights on the dash however may have been looking back as I was parking. The dealer did not find any code to indicate a system failure. They suggested that we removed the after-market mats.

Sudden rapid acceleration of car while parking vehicle on December 20, 2023 at approximately 2:00pm. The sudden rapid acceleration caused the vehicle to jump a curb and hit the base of the light pole damaging the right front of the car. Car was towed to the dealership and is currently there. If the car had not hit the base of the light pole, the car could have continued on into a driving lane possibly striking another car or pedestrian. To date , 12/31/23, the car has not been inspected to my knowledge. There was no warning lamps or messages. While reaching down to push the park button, the engine, which is normally quiet, made a loud whirring noise and then lurched forward.

Chevrolet dealer was unable to install software during 2 hour n212345944 recall service. Stated that due to error codes and were unable to contact technical support for assistance with errors. I was told to reschedule and leave the vehicle for another attempt. My concern is that gm/Chevrolet repeatedly lead me to believe they had a final software remedy and they are not delivering on it. They have had more than three years to fix the problem and I am still being denied full use of my vehicle.

Vehicle stopped while driving down the road lost power threw up multiple codes and was stuck in the middle of the roadway!.

Was sitting at a stop light when I accelerated on green I felt a lurch, it felt like someone had hit me from behind. Within 15 seconds of acceleration this light came on, a car with an exclamination point on it, and said to pull over ASAP. Car would not go any faster than 30mph and luckily I was not on an interstate or major highway. I was able to pull over in a parking lot and at that time the car was disabled. I could not put it in driver or reverse and it did not want to turn off I had to open the door to turn it off. On star diagnostics said it was the electric drive unit not preforming as expected, codes p0a3f and p0a40. Car would not move and luckily it was daylight in the area I was at, at night this would have been bad as I would have feared for my safety as a female alone in a car that would not go. Car had to be towed to dealership and from the dealer "drive motor position sensor erratic. Found bulletin 19-na-220 to replace engine harness (42840881 2525c f-harness) for this concern due to improper instatallation of harness causing issues due to terminal damage".

This vehicle left me on sept 13 in the middle of the freeway bc it lost propulsion. I had plenty of charge and all of a sudden my charge was gone. The car wouldn’t speed up. Had to pull over and wait 4 hours for tow truck.

General motors is making brand new Bolt Ev/euvs using batteries that are supposed to be used to fix cars that could potential catch fire. They stated that the old vehicles effected by the recall would be given priority. I have had a bolt euv on reserve that has been waiting on a battery replacement for over a year. Gm will not inform me or the dealership of when it might be repaired. Concurrently gm is making and selling new bolts that use the battery pack that could be used to fix the old bolts. It is criminal that they would allow dangerous vehicles to remain in public while they make brand new vehicles for profit using the part that could fix every single old vehicle. Based on gms public response to the matter they are false advertising their response to “prioritize cars” that are already made that are faulty. Instead they are prioritizing new cars while leaving thousands of hazardous cars in dealer lots and on the street. If gm can make new batteries for new bolts and sell them then they can take care of the recall. I have had extensive conversations with several dealerships confirming that gm is shipping them new bolts while allowing defective bolts to sit for over a year. I have had conversations with gms concierge desk where they confirm the same behavior. These actions by gm are fraudulent, dishonest, and a danger to the public.

The contact owns a 2022 Chevrolet Bolt Ev. The contact stated while pulling out of a parking lot, the vehicle stalled, failed to shift into gear and would not turn off. A towing agent disconnected the battery and the vehicle turned off. The vehicle was then towed to the dealer where it was diagnosed that the service disconnect fuse had blown. The vehicle was repaired; however, the failure reoccurred while driving. The vehicle was towed to the dealer where the engine control module (ecm) was replaced, however, the failure reoccurred upon starting the vehicle. The vehicle was towed to the dealer. The vehicle was not repaired. The manufacturer was notified of the failure and a case was opened; however, the manufacturer had not followed up or returned the contact's calls. The failure mileage was approximately 6,612.

Four times during a cross country trip, after a level 3 DC charging session, the car would either not start or if it did would not shut off. The gear could not be shifted into reverse or drive and the radio, ac all shut down even though the car was still on. The service soon indicator light came on. Diagnostics from on-star said that it was the propulsion system. Another indicator light came on saying conditions not right shifting. The fifth time it occured while the car was moving and unlike the four previous times the gear couldn't be jiggled or temporarily rebooting the car by removing the 12-volt battery. The car had to be towed to the dealer where it was announced that drive control wiring harness needed to be replaced. This problem is well documented on gm bolt forums. The car should have been recalled before my family was put at risk. I wasted 12 hours during a 19 hour move across the country due to this known problem. I was stranded in life threatening triple digit heat indices.

Euv service soon light came on followed by a propulsion reduced message. Speed was limited and air conditioning was warm. While parked the euv made a pulsating clicking noise. Euv would not go through charging procedure. Euv gave a change complete message with only 81 miles on the display.

Currently, my 2020 bolt has been recalled due to fire hazards. I contacted the local gm dealership north park Chevrolet (castroville TX) and was informed that there is no clarity on the exact part that needed to be replaced in order to make my vehicle safe. I later contacted gm [sr:9-6936321672], in order in inquiring when parts will be parts will be made available for replacement still tbd and no part numbers were provided. I informed gm that even when charging to the recommended 90% that my car gets very hot and makes a loud noise while plugged into the charger, but I was informed that there they are currently still working on a solution. It is unacceptable for an auto manufacturer to sell a vehicle this is a fire hazard is at a higher risk due to the warning signs that gm has ignored.

High voltage battery has been recalled due to fire risk on 8. 20. 2021. No remedy for repair has been performed and I have had difficulty getting information from gm regarding my vehicle swap due to the recall. The vehicle is becoming more unusable as the weather gets colder due to the charging limitations set in the recall.

I am filing a complaint against gm. The following info is from the nhsta website. Original recall date: Aug 20,2021. Manufacturer recall number n212345940. Nhtsa recall number 21v650. Recall status: recall incomplete, remedy not yet available. I have waited over a year for my replacement battery. Gm has seen an almost 15,000 vehicle surge in Bolt Ev and euv sales in the most recent financial quarter. And gm has announced increasing new bolt production by almost 400%. However, thousands of existing Bolt Ev owners are still waiting for replacement batteries. Gm continues to state that parts are not available. Clearly, with the surge in sales and gm’s plan to increase bolt production, parts are available. Existing bolt owners have suffered for years with defective batteries that none of us known if or when a battery will catch on fire and kill us or damage property. I urge the nhsta to put pressure on gm to replace defective batteries first before selling cars with nondefective batteries. I would not be complaining if gm was not clearly prioritizing profits over people. Gm is making nondefective batteries but makes existing bolt owners wait over a year for a replacement while gm takes in revenue and generates profit. The defective batteries catch on fire. None of the batteries existing bolt owners should have to wait this long for replacement batteries and suffer with anxiety and stress not knowing when or if their car battery will spontaneously ignite.

I received a recall notice for my 2018 chevy bolt and my complaint is in reference to that. It is not a new issue. The remedy suggested by the recall notice is completely unrealistic. To use the car, I have to charge it overnight when I am sleeping. As is the case with almost every other bolt owner, my charging station is in the garage. So it's unrealistic to (1) avoid depleting below 70 mph range, (2) park my vehicle outside immediately after charging, and (3) avoid charging the car in my garage overnight. I just want to make sure gm does not escape liability if there is a problem and I did not follow these unrealistic guidelines.

I received a recall notification regaring our 2020 chevy bolt which was purchased only six months ago. Not only is chevy not providing any indcation as to when our car will have its battery replaced (the dealer suggests it could have six months or longer), their proposed interim fixes are completely unacceptable and unworkable. If we cannot charge the car more than 90% and if we cannot go below 70 miles, the effective range has been reduced by roughtly 50% or about 100 miles which frustrates the entire reason we purchased this car (we commute approximatel 120 miles round trip each day). They are not offering to provide a rental or substitute car nor are they offering to take the car back and I'm now stuck with a poorly made hunk of metal and lithium with no idea when we will be able to use the car again.

I own a 2017 Chevrolet bolt which is part of the recall announced today by gm. This is the second recall in less than a year for the same battery-related issue. It was supposed to have been fixed with a software update in June. This software was supposed to identify defective batteries but it has not been successful as evidenced by the mounting number of fires that have happened after the “fix”. As such, we are now under a recall a second time. As a result of their own manufacturing issue, we are now limited to how we charge our vehicles, where we park and even the mileage range that we paid for, while gm attempts another fix. Gm stated today that they will again be using software to identify defective cells in our batteries and only the ones that are deternined to be defective will have those cells or battery packs replaced. As you can imagine, I no longer trust gm to be able to successfully identify whether or not my battery is defective. I’m extremely disappointed by the fact that gm continues to cut corners in an effort to save money, despite such a serious safety issue that can affect so many. Myself, my livelihood and even people I park next to while out in public are at risk. Gm must be forced to replace the entire battery pack in every vehicle affected by this recall. They must also provide loaner vehicles, or details on reimbursement for rental cars, to those who need them due to the fact that their vehicle is virtually unusable while they clean up their mess.

There have been more vehicle fires after the safety recall "fix". General motors has not said anything yet, and I am afraid to use my car or leave it near anything because of fire risk. This is a great safety concern for myself and others around me. I would like gm to say something.

The battery has the potential to catch fire while it is charged or parked. The given precautions provided by gm makes the car unreliable and unusable. The battery and the vehicle is on usable due to its limitations based on charging. Gm has no remedy for this vehicle.

As I started to leave the driveway in a forward driving position, my brand new chevy bolt with only 2430 miles on it put itself into park. It made a terrible metal grinding noise and jolted us forward. My foot was still on the accelerator because I thought it was going to drive but it stopped then I looked around trying to figure out why. The “e” break was not on and I realized that the car was in park. Nothing was around the drive stick. Nothing touched it and I believe it put it’s self into park when I was driving. This was very scary to us and I did not know what to do so I called the chevy dealer where I bought the car and they said to bring it into get checked. On my way the accelerator pedal started to wiggle and shake slightly.

There was a recall on chevy bolts ev 2017, because a fire occurred. Chevy advertise that it cars get 234 miles on a full charge. This is not true and false advertising from the GMC manufacturer. Since the recall and the vehicle had to be recalibrated to 90 percent, the car get much less than 234 miles . This is important because this a all electric car. Is this not false advertisement?.

My vehicle is impacted by the following recalls: 1) manufacturer recall number n202311730, and 2) NHTSA recall number 20v701. A fix was supposed to be in place by January 1. I followed the manufacturer's steps to reduce charge capacity and waited patiently until 1/29 for the fix. On 1/29 I called gm concierge line at that time to inquire about the status of the fix. I was told there was no update. I inquired about my options including a buyback or replacement vehicle in addition to a loaner car during the period of time the car was out of commission. I was told no problem and someone would contact me. I've received two calls since that time, and none of the promised steps including buyback, replacement vehicle, or loaner cars were offered. The representatives do not respond to my emails, when I call, the assigned rep ignores my calls, and when I ask for a status update I'm told there isn't one. Gm is clearly delaying the issue. I have informed gm that my vehicle is parked in a very close quarters garage where a fire would create an imminent life/safety issue. Gm continues to not respond to my inquiry. The vehicle meets the requirements of the nonconformity vehicle under the tanner act and I am requesting assistance to ensure that the vehicle is repurchased or replaced. There has already been confirmation posted that the battery packs need to be replaced on these vehicle and gm is not acknowledging their responsibility to issue a fix to the vehicle and prevent further injury. I am writing to request an inquiry by NHTSA into what gm is actually doing to prevent further loss of life and/or injury and to repair or replace my vehicle. I have documented weeks of emails on the topic with gm which are not being replied to and am not sure where else to turn to get gm to address this open safety issue. Thanks.

In November 2020, general motors has decided that a defect which relates to motor vehicle safety exists in certain 2017-2019 model year Chevrolet Bolt Ev vehicles. This notice applies to my vehicle, VIN: 1g1fx6s04h4179162. As a result, gm is conducting a safety recall, n202311730. More specifically, a certain number of these vehicles were built with high voltage cells produced at lg chem's ochang, korea facility that may pose a risk of fire when charged to full, or very close to full, capacity. The severity of the recall notice was alarming to my family as we drive it daily and often extended miles. Safety is my primary concern and I am requesting remediation immediately. The risk and danger is too great for me to wait and see as gm investigates. What recourse do I have now?.

The first year of the lease, the main computer began to fail and the entire screen would become black, with the entire car intermittently losing power on the freeway. The computer was replaced. Later on, the blind spot sensors became erratic, but this is likely due to a shoddy repair by the dealership after someone rear-ended the car. The primary concern is the powertrain. The battery range decreased by nearly half while driving, which would have been dangerous in a remote location. There seems to be an issue with the battery modules on the 2018 Chevrolet bolt.

I am an owner of 2019 chevy bolt. I had this car since the day 1, baught it brand new from the dealership, and not only when I purchased it the dealer had no proper information abut it, I have tried contacting the gm customer care regarding the first, second and third recall. I have asked the gm regarding the recall, if the recall that the dealer will try to fix will not solve the issue, will I still be in the risk of having my car catch on fire? can the gm guarantee me that after having all of my recalls done prior to the final one that just came in that they had fixed the issue and that my vehicle is safe now considering I have a child. The response was: " we cannot guarantee that to you, because we can only try and see if this will solve the issue. " so the issue is not solved, my vehicle is a danger not only to me but to my neighbors and to my family. Foremore, gm does not want to buy back the vehicle even though they know it is their mistake and it is their defect.

Vehicle unexpectedly & without warning lost power while traveling on highway. Vehicle was unable to accelerate and all power from the high voltage system was lost.

While slowing to make a stop at an intersection, the vehicle experienced sudden acceleration and would not stop. The car struck the vehicle in front of it a couple of times and continued to accelerate.

Got the message: propulsion power is reduced I could start the car but not shift gear. Got the error "cannot shift gear conditions not right ## #vpic# 1 - check digit (9th position) does not calculate properly #vpic#.

My 2017 chevy bolt lost propulsion while in motion on city streets in los angeles in traffic without warning from either on star or the vehicle. The battery indicated approximately an 60% charge. The vehicle is now at el camino Chevrolet in monterey park, CA. , waiting on service.
