2017 Chevrolet Bolt EV Powertrain & Transmission Problems

I started losing Regen braking intermittently, when this happens the brakes themselves don't work well and there's no warning, you lift of the pedal expecting the car to stop and its rolling freely, to push brake and its not stopping like you expect, then it thuds and lunges forward a bit and stops. It was rarely happening, now the car can barely be driven. I have not got it into a shop yet. It throws DTC P182B, P182D, P1840, and U0401 every time. Clearing them, even while still moving brings it all back to normal, except an image of my previous drive will be frozen on infotainment that I have to hard reset to get it to work. Also backup camera does now work when these codes are active. I have found 1 person online that is having this exact issue. It's terrifying to approach a stop light and used to 1 pedal driving and I'm rolling freely instead. the first incident of it was 03/05/26 and has progressively worsened. My code scanner keeps records of when I clear the codes,

My wife of [XXX] and grandson were driving our Chevrolet Bolt, crossing a busy 4 lane highway when suddenly and w/o any prior warning, the Bolt lost propulsion. Caught blocking 2 of those lanes, she was fortunate that men stopped their trucks and pushed her car up hill and into a church parking lot. She called me and I tried resetting everything to factory settings, and the Bolt seemed okay-for a short time. I hooked a diagnostic unit to the car and found an error code that indicated either the failure of the pre-charge resistor or the HV contactor-both in the battery pack. This was a pack replaced by the dealership back when Bolts were randomly catching fire and destroying themselves and nearby property. Now these packs are failing again and there are service bulletins addressing this fact and that it is common in 2017 and 2018 Bolts. GM however has not sent out warnings to its unfortunate customers warning them of this common failure and life- threatening problem. Luckily today I'm dealing with the Bolts warranty rather than two funerals. All of that took place on 11/22/25. In the hour following the first failure, this situation repeated itself 4 more times. The last time there was no restarting it, or the car would shake if put into drive or reverse. As it was Saturday we had to wait until today 11/24/25 to get it towed to the dealership for $140. This failure will require dropping the battery pack and running three tests, then replacement of the faulty components. This should be under warranty according to our and the dealerships records, but this issue need to hit the national news and all Bolt owners should be sent letters warning of sudden and unpredictable failures. This was life threatening for us and will be for many others. Imagine this happening at interstate speeds in heavy traffic. Lives will be lost. This is the second and more dangerous failure for these horrible vehicles, and GM should at this point replace these or refund every owner. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATI

The contact owns a 2017 Chevrolet Bolt EV. The contact stated while the vehicle was parked, the vehicle suddenly lunged forward. The contact pumped the brake pedal several times, but the vehicle continued to drive forward. The contact was able to avoid crashing into an apartment building. The vehicle went airborne for 30 feet and landed on the street causing the tires to blowout, and two of the rims to be cracked. The contact’s wife suffered a head injury and sought medical attention. No police report was filed. The vehicle was taken to the dealer; however, no failure was found. The vehicle was not repaired. The manufacturer was contacted and stated that the case would be escalated. The failure mileage was 72,000.

The issue with the current recall is that it is impossible for those with long commutes to adhere to the not charging overnight and not going below 70 miles of range. While I do not expect any battery failure I would like to be sure that the vehicle will be replaced by GM if the vehicle were to be damaged by the battery even though I am not following the recommended actions due to needing to use more of the range than is recommended at this time.

I had my Chevy dealer install the second software update and return my battery charging to 100%. There are now two reports of Bolt EV erupting in flame within a couple weeks of each other and both vehicles had the recommended second software installed. I'm reporting that the fix GM has come up with does not work and does not prevent the initial problem of battery fires when vehicle is left unattended. My safety and the safety of my family or other passengers are at risk of a fire starting for no reason and there's no solution offered by GM for this issue. Neighbors are put at risk just by the presence of this vehicle in my driveway. The general public at large are also put at risk if I was to leave the car in a public parking structure like an airport or downtown parking. Waiting on the NHTSA to do something about this to protect the safety of the public.

THE DEALERSHIP PERFORMED UNAUTHORIZED SERVICE ON THE VEHICLE. IN CONTACT WITH THE MANUFACTURER(GM) THEY ARE IN WILLING TO REVERSE THE UNAUTHORIZED SOFTWARE UPDATE UNTIL A LONG TERM SOLUTION HAS BEEN IDENTIFIED. I HAVE OPENED A CASE 1 WEEK IN ADVANCE AND NO RESOLUTION HAS BEEN COMMUNICATED ABOUT THEIR RESPONSIBILITY OF RENDERING MY VEHICLE UNUSABLE.

STOPPED AT STORE1/24/2018 WHEN TRIED TO RESTART, RECEIVED TRANSMISSION WARNING SERVICE SIGN, UNABLE TO MOVE ATTEMPTED 3 MORE TIMES OVER 2 HOURS. FINALLY IT RAN, BUT SERVICE TRANSMISSION LIGHT STAYED ON. TOOK TO DEALER. TOLD IT WAS A COMPUTER UPDATE THAT WAS NEEDED, IT HASN'T HAPPENED SINCE. REVIEWING CHEVY BOLT FORUM, APPPARENTLY I AM NOT FIRST OWNER SERVICE TRANSMISSION WARNING HAS COME ON WITH CAR DISABLED IT WAS STATIONARY WHEN SERVICE LIGHT FIRST CAME ON. HAD DRIVEN A MILE AFTER WORK DAY. HAD WELL OVER 50 PERCENT BATTERY CHARGE LEFT I WAS NOT GIVEN MUCH INFO FROM DEALER, JUST IT HAD BEEN RESOLVED BELOW IS WHAT IS ON MYCHEVY.COM SITE ABOUT ISSUE REPAIR FROM DEALER PRINT SOURCE DEALER ODOMETER READING 1,755 SERVICE LOCATION SERVICE INFORMATION SERVICE #: 055209 SERVICE PERFORMED: ENGINE ELECT CONCERN NOTE -------------------------------------------- TOLD NEEDED UPDATE ON COMPUTER, TRANSMISSION DIDNT WORK

THE PROBLEM IS THAT IT IS TOO EASY TO PUT THE CAR IN "PARK" BY ACCIDENT. ON SEVERAL OCCASIONS, I WAS TRYING TO GO FROM THE "L" POSITION TO THE "R" POSITION. TO DO SO REQUIRES YOU TO PRESS THE SIDE BUTTON AND MANEUVER THE SHIFTER TO THE R POSITION. ON SEVERAL OCCASIONS, WHILE DOING SO, I INADVERTENTLY PUSHED THE "P" BUTTON ON TOP OF THE SHIFTER RESULTING IN THE CAR ENDING IN PARK WHEN I WANTED TO REVERSE. THIS HAPPENS WHEN I GRABBED THE SHIFTER AND PRESS ON THE "P" BUTTON WITH MY PALM WHILE TRYING TO PRESS THE SIDE BUTTON. MOST OF THE TIMES IT WAS NOT A BIG DEAL, I JUST TRIED AGAIN AND THEN PROCEEDED. HOWEVER, ON ONE OCCASION TODAY, I WAS ABOUT TO MOVE INTO AN INTERSECTION WHEN A FAST MOVING CAR APPEARED FROM A BLIND SPOT AND I TRIED TO QUICKLY BACK-UP AND ENDED UP IN PARK INSTEAD. IT TOOK ME A FEW SECONDS TO REALIZE WHAT WAS GOING ON AND FINALLY GOT IT IN REVERSE BUT IT WAS POTENTIALLY DANGEROUS AS I WAS IN PARK IN THE INTERSECTION WHEN I NEEDED TO MOVE QUICKLY OUT OF THE WAY.
