Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The antilock safety is preventing me from starting my vehicle. When it does start, and I go to an intersection to turn the truck will then stall out. It can cause a wreck. It is a huge safety issue, time consuming, and money consuming when I have to wait 10 minutes to try to start my truck, or it doesn't start, I have to replace it for $450+ which I don't have to replace the ignition switch and it's dangerous because if it does let it start I have to be careful because it will stall out on any given second causing a catastrophe!!! …”
NHTSA complaint #11415729, filed 2021-05, 100,000 miles“I have been having security issues with this vehicle for the last 2 years. Keeps me stranded at times until the system resets itself. My hood is rattling and am afraid one day it will come off. Don't want to trade it in but may not have a choice. If companies are aware of these problems they need to fix them before someone gets killed or seriously injured. It is a total shame that consumers have to deal with all these problems and by the way paying high car or truck notes a month and having to deal with extra problems we don't need or want. …”
