2023 CHEVROLET BOLT EUV Electrical System Problems

The lane departure warning goes on and off randomly. The heating stopped working. There are glitches on the screen interface. And yesterday a red light with a car and exclamation mark through it came on. I took it to the dealer and they only had time to check the code which came up as "hybrid/ev powertrain control module requested MIL illumination" The advisor who is not an ev technician told me not to worry about it because the light went off. Everything i am reading online says this could be a huge safety issue. When I reported it to the manufacturer, they told me to listen to the dealer without getting more information and would not transfer me to a manager. I am concerned for my safety and the safety of others. And I am finding Chevrolet to be negligent on what could be a huge hazard.

I’ve experienced multiple instances where the Rear Cross Traffic Alert system on my 2023 Chevy Bolt EUV fails to function properly when the vehicle is shifted into reverse. Specifically, there are times when the system does not emit any audible warning despite approaching cross traffic, and in other cases, the alert system appears to be completely unresponsive, no visual indicators or chimes occur at all. This happens intermittently and unpredictably, regardless of weather conditions or terrain. The issue is concerning because the system is a critical safety feature intended to warn of vehicles or objects approaching from the side while reversing, particularly in parking lots or driveways. The lack of warning increases the risk of a collision, especially in areas with obstructed views or high pedestrian activity. This appears to be a defect in the sensor system or software that controls cross traffic detection. I believe this poses a significant safety concern and may affect other Bolt EV vehicles.

This model has a dangerous driving problem that is difficult to reproduce; however, it points to a flaw in a coupled design that causes simple infotainment system failures to negatively impact both on-star help system and critical driving system. This problem recurred on [XXX] in suburban area of Buena Park CA; previous occurrence in 2024 had purported possible resolution through software download. It begins with simple problem of inability to change FM channel; checking other controls on infotainment screen showed all displays responding correctly, including commands to change station; yet it does not. Only after car has been parked and EV motor turned off for awhile, did this problem reset. This is an indication that previous problem remains unresolved. Previously, on an isolated section of AZ highway without cell service, what began with radio control malfunction ended with this model turning off all speakers and all displays. Once speakers were turned off, on-star interaction can not be heard in the car. I expected separate speakers for on-star emergencies; however, to my surprise it seems to be routed through or related to infotainment system. Then possible stops and attempts to reset the infotainment system through turning off the car, caused all lights to go off on the dash. I had to drive many miles through isolated desert and mountains to reach a safe offramp with no instrumentation. This makes suspect what else could go wrong when in isolated regions. So far the danger seems to be related to driving in no cell service area; however, without further investigation, this design of coupling infotainment system with both critical driving and emergency systems makes this model unreliable and dangerous to everyone in this car. Please investigate and decouple these systems. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Software in the EV system created to protect the battery pack has instead placed my life in jeopardy in response to known false sensor event. During 110 degree heat in isolated desert in southern California, the software detected a false error in high voltage comparisons between battery banks. In response, it disabled climate control, reduced propulsion, and placed an upper limit of 40% on battery recharge system. Without any warning nor noticeable malfunction during the drive out to the desert truck stop, 1 hour of fast charging at 50 kWH resulted in the charger being turned off by the car after reaching only 40%. With no info, I just assumed that this was a failure of the charger; however, I had used this specific charger 1 month prior without any problems. Only after I left this truck stop and headed to the next electric charger, some 50 miles away, did I notice the lack of A/C and warnings on the dash. At this time I called Chevrolet Roadside Service(CRS) and received advice to proceed to the charger then if charging attempt fails, call them back. I drove in 118 degree with open windows behind the slowest moving semi I could find. Within minutes my connected phone for map guidance, started overheating from both the environment and the car charging my phone. I realized I could die out here without car nor phone. Upon arrival, my attempts produced only 4 kWH charging speed at a 50 kWH station. After many false guidances and about 6 calls to CRS and 1 day, I was able to get my car towed to nearby Chevrolet dealer who was too busy to look at the car for 2-3 days. Next day I picked up my car and drove in 102 degree heat to where I purchased this car 2 years ago. 2 days later I picked it up; a known problem solved by a software download fixed it.

The battery charging system is malfunctioning and won't charge the battery correctly. Hazards from a battery and charging system that is not functioning. Possible battery explosion during charging. Possible fire to car & garage / home. Yes Yes Yes

I have owned the car for less than six months and the battery went from full charge at 230 to know a full charge only being 180. I’m also sitting here at a dc charging station and have been here for an hour and a half and still haven’t reached 80%. What do I do?

The contact owns a 2023 Chevrolet Bolt EUV. The contact stated that while driving at various speeds, the automatic emergency braking system engaged while there were no vehicles or objects nearby. Additionally, the contact stated that while driving at various speeds, the Super Cruise driver assistance feature disengaged unintendedly. The contact stated that upon attempting to reengage the feature, a message advising that the road lane could not be found or that the contact's face could not be read was displayed. The vehicle was taken to the dealer several times. The dealer informed the contact that the vehicle was operating as designed. Additionally, the contact stated while driving 50-60 MPH on the left lane, the Super Cruise driver assistance feature disengaged unintendedly, causing the vehicle front bumper corner to hit the wall on the driver's side. The contact stated that the driver's side of the vehicle also hit the wall and the vehicle stopped. The contact stated the front driver's side wheel and axle were fractured. The contact hit his head against the driver's side door during the incident and sustained pain, but did not seek medical assistance. A police report was filed, but the contact did not have the police report information available. The vehicle was towed to the dealer but was not diagnosed or repaired. The vehicle was then towed to Body Works on Grand, Inc.(6134 W Grand Ave, Chicago, IL 60639) to be repaired. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 27,000.

Dashboard went blank for a second and reset itself twice while driving at 65 mph in the mountains of AZ, near sunset. This happened once in 18k of driving, right after infotainment system partially failed: audio failed and parts of touch screen failed to respond. Danger is in the unsuspecting driver's reaction in poor driving conditions. Call to On Star was initiated but it uses the same audio system the infotainment system uses. So On Star failed. Pulled over; restarted car several times, infotainment system was silent. 2 hours of driving in silence; parked for 2 hours; restarted car and everything was back to normal. Took it to dealer. Unable to recreate this problem. Updated software downloaded to infotainment system. No information if this fixes problems. Until we understand why infotainment problems may cause dashboard to go dark, this car is unsafe for unsuspecting drivers. My wife was driving; I in passenger seat, she won't be driving this car again until this is understood better and fixed. Thank you for your help

Last month I ran out of battery before getting home when the weather was 15 degrees and windy. Without my knowledge the vehicle was heating the battery significantly reducing the remaining range, no vehicle indicator warning that the vehicle was conditioning the battery. I realized what was happening when I turned on outside venting without using heat to defrost the window and the air was hot, if I was new to the vehicle or on my first trip I would have been stranded in an area where there may not have been a place to pull off the highway. I decided to report this in case it can save even one person’s life, there is an increased danger and liability not knowing this information. As most people, I set the cruise and pay attention to the road so majority of the time you don’t see the unknown increases in the kW usage, an update should be required to show an alarm of some sort and the additional active kW consumption and expected range deduction when the vehicle is doing any kind of conditioning (heating, cooling, or maintenance). There is a battery maintenance % view that should be modified to accommodate this.

Near my work place, I drove by that intersection a numerous times. One day, when I almost finished making the left turn, it suddenly gave me collision warning and suddenly took brake on the left front wheel by itself for about 1 second. There was nothing in front of me.

What component or system failed or malfunctioned, and is it available for inspection upon request? - I believe it is the electrical component, or wiring component that is under the hood. It spontaneously caught on fire in the middle of the night with no indication of arson or outside source. How was your safety or the safety of others put at risk? Definitely a safety concern since how would anyone know if their car will not spontaneously catch on fire while driving, parked, inside a garage? Not only my own safety concern, but for my family and neighboring houses/cars' safety as well. Has the problem been reproduced or confirmed by a dealer or independent service center? GM Claims department only stated that they went by NFPA921-2021. However, no detailed report was produced, or at least they say it never did, even though we requested more than two dozen times. And evidently, just closed the case without giving us a valid reasoning or evidence of anything. And as for the NFPA921-2021, it is two years old already. Please keep in mind that GM had this car for almost 3 months for investigation but no report, reasoning, or any valid understanding for a consumer's point of view. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? GM said they did but no investigation report or work report or anything related to that has been provided. NO EVIDENCE, NO TRAIL, NO INVESTIGATION REPORT. Only denial letter. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear None of the warnings were shown prior to this. 3 months of investigation from GM, but no reports, no investigation report was produced or provided. How can we as a consumer, believe what they are doing is valid and fair?

Frightening SAFETY Problem: Sudden Power loss on Los Angeles freeway. About 6/21/2023 began repeated episodes where my Chevy 2023 Bolt EUV hesitated for a few seconds before responding when I pushed on the accelerator pedal. Full power and acceleration resumed right after the initial hesitation and were sustained until I had to stop the car. A dashboard warning light appeared. I called for an On-Demand Diagnostic evaluation, spoke by phone with Chevrolet support who assisted with the evaluation and emailed me the results (screenshot) indicating an issue with the HCP - Hybrid Control Processor Module and a Diagnostic Code P2797. The Diagnostic Information read: "The Electric Drive Unit is not performing as expected. An issue has been detected in the Auxiliary Transmission Pump System..." The “Recommended Action” was to “Service within 7 days.” (Screenshot) I contacted the dealership where I purchased the car and was told that I would have to leave it for several days before evaluation/servicing could be done. However the next morning (before I could take the car to the dealership) the instrument panel alert had disappeared. So I considered it all a temporary "glitch". Then on 8/27, driving about 60MPH on very busy 405 Freeway in Los Angeles, the car suddenly lost most of its power and slowed down…with an orange dashboard warning icon “Propulsion Power is Reduced” and another message that speed limited to 30 MPH. Alarmed and fearful, I turned on emergency blinker lights, moved to right lane and exited freeway at next off-ramp. The problem persisted as I slowly drove surface streets to destination and parked. Several hours later I started car; alert message came on but car accelerated normally. I slowly drove home on surface streets. On 8/29 another Chevy dealership identified "Scanning Code P2797" and "Replaced Transmission Fluid Pump” by warranty coverage. No problem since. Service manager said she has seen 3 similar problems. I see similar reports online.

After rain, the locks on the vehicle would not lock or unlock whether by using the key fob, interior door buttons, or OnStar app. After approximately 2 hours the locks began working again.

Was driving along and received a “Propulsion Power Reduced” warning on dash and couldn’t go over 30mph while on a highway. Had to limp along on the shoulder. Pushed the OnStar button and they ran a diagnostic test which came back with P2797.

I just bought a new chevy bolt euv from a dealership here in Michigan. No sooner than me driving off their lot, a pickup truck damn near ram into me. I was in thick traffic following slow vehicles and the only damage cause was a skid mark on the road he cause. No damages to my bolt. He roll down and said fix your brake lights. I yell back, it's factory! I'm scared to hold onto this vehicle when it comes to winter time. Most vehicle's license plate get obscured by snow. These brake lights and turn signals are even below the license plate. A recall and a redesign needs to happen. Too many people expressing negative opinion on this issue on the forums. Thank you for reading this. Have a great day.

I just bought this vehicle this Sunday. I drove about 400 miles and Wednesday, I got warning ⚠️ electric drive unit ⚠️. Yesterday I took my car to dealership and got call from them that auxiliary transmission issue and they will replace it. Car is still at the dealership, now we are afraid to drive that car and what if it jeopardizes our safety. We drive a lot for work as a home health provider.
