Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The recall is not yet completed on the battery after more than a year. The range of my car is limited severely since I can neither charge the battery completely nor let the charge decline below about 30%, essentially reducing the range to 60% of what was promised. This is a known issue and GM has had plenty of time to fix it. I have contacted the dealer on many occasions and they have not been at all helpful.”

NHTSA complaint #11500599, filed 2023-01

“The car can blow up and catch on fire due to excessive heat and humidity. Dealer is responsible for fixing it but it's been over 2 years and I want to end my lease early due to safety concerns. I have barely driven the car and kept it out of the garage (except for charging) but fire safety concerns are not being addressed by all Chevy dealers in Houston. No one can fix it and even if they did, it would take months so I want to turn it in to dealership and get someone to fix it so they can resell it safely. …”

NHTSA complaint #11526891, filed 2023-06

“I am reporting an issue that may affect every Chevy Bolt EV owner and possess a serious safety issue for children. I discovered this issue while being an owner of two 2021 Chevy Bolts. I discovered that if a key is locked in the vehicles back storage area while the vehicle is running no door will open. If children are in car seats and the child lock is enabled the children will be trapped until a window is broken. This could be fatal if the vehicle was set in motion some how, which is not hard. …”

“How was your safety or the safety of others put at risk? Drivers have to follow unfair guidelines that cripple the car. I am not able to follow the GM guidelines without affecting my livelihood and how I use the car to commute and charging procedures overnight to achieve the needed range for daily commute. 1. Set your vehicle to a 90 percent state of charge limitation using Hilltop Reserve mode (for 2017-2018 model years) or Target Charge Level (for 2019-2022 model years) mode. Instructions on how to do this are available in the videos below. …”

NHTSA complaint #11433275, filed 2021-09

“It was recently brought to my attention that the Bolt EV vehicles have a very serious battery issue. I have not received any written or emailed information regarding this issue from Chevrolet and instead happened upon this issue in my social feeds. It is my understanding that the batteries pose a very serious risk of fire to the point that I must charge my vehicle below maximum capacity/range, I must not drive the vehicle to it's maximum listed range, and park it outside while charging so that the potential of my house catching on fire might be averted. …”
