Chevy Volts from 2016 - 2019 all have a manufacturing defect which can prevent the driver from powering - the error message is "Shift to Park". GM released a Volt Service Bulletin in May 2021 but offered no assistance to replace the defective part. On [XXX] I was driving home on [XXX] headed [XXX] from Santa Cruz in fair weather in the afternoon. This highway can be dangerous with limited shoulders and poor visibility, making it an unsafe place to pull over. While traveling at about 55 mph, the car made an alert sound and illuminated the check engine light and presented a message "Shift to Park". I was running out of room on the shoulder to pull off safely so I had to make the quick decision to pull off to the left-hand shoulder. I followed the instructions on the display which said to shift into park, followed by shifting back into drive. During this time I had my foot on the brake, but after removing my foot from the break, the vehicle began to roll towards traffic, so I put my foot back on the break. I tried powering the car off/on multiple times and tried to get the car to go back into drive but was unsuccessful. Eventually, I put the car back into park, called a tow truck driver, and waited for over an hour to have my car safely towed off [XXX]. Prior to this, I had not experienced any of these or similar symptoms. An OBD code scan was done (screenshot attached). Once at the Chevy dealership, they confirmed that the car could, at that time, shift into park and were not able to reproduce the "Shift into Park" issue. However, they reported that the car was revving high and the transmission would not shift into the proper gear ratio. The dealership was not able to fully diagnose the problem and instead suggested to replace the entire transmission as assembly and then continue investigating. We reached out to the manufacturer, Chevrolet/GM, about the issue(s) and were ed case # [XXX] while they work with the dealership to investigate further.

I ran into a vehicle in front of me during normal traffic on my way home from work, two months to the day of picking up my 2018 Volt. The vehicle ahead of me may have stopped quickly, but it was not a stop the Volt shouldn't have been able to handle. I was on a street in my neighborhood I drive every day in traffic. I had mentioned to friends and family that the Volt's brakes just did not feel on par with the rest of the car and would be the only aspect of this ev experience I found lacking. I have the dated text messages to prove this. Now I have a Volt at the body shop for the 5th week (lacking an ac line for reassembly), an over 55% increase in my insurance premiums (per the renewal notice I just received) and what really hasn't been a good experience. While I'm waiting for the return of my Volt I have received the important safety recall indicating the braking performance may be reduced. If the car had been able to stop two feet shorter I'd have an undamaged three month old Volt and my insurance standings untarnished. That two feet ended up costing over $17,500 to the car. Turns out Volts are also expensive to repair. I'm a 55 year old male, no wild kid. Still stuns me that in 2018 GM can't get brakes right...the most important of safety systems.
