2020: “While driving on the interstate, I received a warning about an electrical system malfunction. As I neared my home, I received warnings about transmission failure, suspension malfunction, steering malfunction, sensor failure, and more. After a tow to the dealership I was told it is a generator/alternator (?) failure and the part is on national backorder and may be 3 months or more.”
NHTSA complaint #11508031, filed 2023-022021: “Today, I was in a protected left turn lane prior to making the turn. When oncoming traffic (4 lanes) cleared, I gently pressed the gas pedal to start the turn, but a red “pre-sense” error triggered and slammed on the brakes. I moved my foot to the brake and then back to the gas, and the error cleared, allowing me to continue the turn. This was dangerous as I could have stopped in front of oncoming traffic or been rear-ended by the car behind me. …”
