2019 Chevrolet Bolt fuel/propulsion system problems

“While driving on the freeway at 65 mph during morning rush-hour, the vehicle unexpectedly decelerated without warning and came to a stop. The vehicle was barely able to make it to the shoulder before losing all momentum. There is a high-risk of a fatal collision when a vehicle unexpectedly stops or drastically slows on a freeway with 65 - 70 mph traffic, which is compounded during peak travel times. This is a risk to not only the vehicle occupants, but other drivers and vehicles as well. Several error messages were displayed on the dashboard as the car was decelerating: Drivetrain malfunction: Stop and turn off engine; Service high voltage battery system; Service Vehicle Soon; Unable to shift. The battery range dropped from just under 50% (~115 mi) to 0 while attempting to pull over on the shoulder. After the vehicle was stopped, it was unable to be powered off for about an hour. It was not successful in shifting or moving and the battery range showed 0. An hour and a half (1.5 hours) after the incident, the vehicle would power on and show a battery range between 121 - 110, which would drop to 0 within 15 seconds with a message that it is unable to charge. At…”

“After driving the car for roughly 60-75 minutes while at highway speeds and within the posted speed limits: 65mph-75mph, the car will chime and the driver information panel will flash "Propulsion Reduced." At that point, the vehicle's electrical propulsion will gradually reduce to a maximum output power of roughly 20KW. The propulsion will stay capped at 20KW for a bit of time (15-20 minutes) and then gradually the cap will increase. Unfortunately, on I-25 in southern Colorado where this usually occurs, the speed limit is 75mph and and 20KW of propulsion results in the vehicle traveling on the interstate at roughly 45-55mph which results in very unsafe situations. That road has a minimum speed of 55mph. This happened on the first day that I purchased the car, I can reproduce it with my family in the car, but the dealer has been unable to reproduce it. I have had the Chevrolet dealership inspect it multiple times, but they can not find a fault. It has happened when ambient temperatures are as low as 28F and as high as 98F there does not appear to be a correlation there. I have had it happen when the battery has a SOC of 70% and as low as 25%, that also does not…”

“Vehicle without warning stopped moving while making a left turn in an intersection at night. Power to dashboard was on but no propulsion, brakes or steering. Was unable to put car into gear to move forward or in reverse. Message was displayed, "Unable to Initalize Propulsion System" Extremely dangerous situation, I turned on flashers and left car in intersection. Called tow truck. When tow truck arrived, we pushed car to curb and he hauled it away. Cheverolet dealer diagnosed the problem as a defective wiring harness. He said there was a GM alert regarding this as a known issue that led him to the defective wiring harness. They charged $1567 to replace it which included $1200 in labor and recommended I contact GM to see if they would compensate me since it was a known issue and the car was only 2 months off warrantee. GM refused to compensate me for the faulty harness. The Bolt has 19K miles on it, is kept in a garage and has never been in an accident.”

“I'm experiencing the loss of propulsion covered in this bulletin. It's happened around 5 times. https://static.nhtsa.gov/odi/tsbs/2020/MC-10176614-9999.pdf The malfunction indicator lamp comes on after each incident and then clears. The problem has been confirmed by a dealer and they are refusing to repair it under either the power train or emission control systems warranty. Losing propulsion is a safety issue, particularly in high speed traffic, and it needs to be fixed.”

“The battery recall on this vehicle has NOT been fixed by GM, your database is incorrect. The vehicle is still a fire/explosion hazard. GM's is not in compliance with NHTSA Recall 21V560 on the Chevy Bolt EV for myslef, a US service member ordered to duty in Germany. I am active duty Navy, and was ordered to duty in Stuttgart Germany, with a transfer date in July 2021. At that time Chevy had cleared the recall, so I shipped the vehicle to Germany. However once it arrived here the recall was reinstated. I contacted GM who said to contact Opel in Germany (their local subsidiary). Opel stated that GM in the US would ship them the parts and they would make the repairs. This was nearly a year ago, and so far NO repairs have been done, and the vehicle remains a hazard to me and my family, and cannot be sold or shipped back. Every time we contact GM (or Opel) we are told they are 'preparing to ship parts', and that it should take 8 to 12 weeks. We wait 12 weeks and nothing happens, so we ask them again, and they say wait another 8 to 12 weeks.. At this point I do not believe they have any intention of shipping parts or repairing the vehicle, and are therefore in…”

“Part of the charging element - the metal clip- locks up and will not allow the car to be plugged in to charge. According to Chevrolet dealer this is a known issue but customers have not been notified by GM. They do not have a fix other than taking the car to the dealer and doing a factory reset. This is dangerous for people who may not discover the problem until their car is too low on miles/charge and may not be able to get it reset. It is happening multiple times, even after dealer reset.”
