| Service Brakes problems |
At random times even while driving: first and most importantly, speed will read 0 mph while driving. Second the following errors will appear on the dash: "steering assist reduced drive with care" "pedestrian friendly alert system" also, the following lights in the dash light brake system warning light service vehicle soon light antilock brake system (abs) warning light service electric parking brake light traction control system (tcs)/stabilitrak light if this happens while driving I have experienced the following: if turning, the steering wheel will jerk because the vehicle loses power steering. If vehicle is in cruise control, the cruise control will disengage and the regenerative braking will quickly slow down the vehicle. I have taken the vehicle to the gm dealership. They had the vehicle in their shop for a month and could not resolve the issue. The last thing they did to the vehicle was a complete reset. This has not resolved the issue and it is happening more frequently now.
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.
My bolt 2021 had break locking issue within 20 days had to get it to dealer n after 12 days they return the car without fixing this particular issue but fixed some 25 other faults. . And after two days again same issue happened and now after more than 2 weeks they asked me to take car back but not giving assurance that same issue reproduced n fixed. . Fortunately both times issue happened in parking lot but I am afraid about it that while on freeway if that happens so dont want to take chance I requested dealer for replacement vehicle which is thoroughly inspected but they asked to deal that with gm directly and I opened case with gm but there is little to no communication from them.
