Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“On two occasions, 8 months apart, our car started braking on its own while driving in traffic. In both instances, the on-screen alerts indicated the LDA and simultaneously the check engine light. Neither time were we trying to switch lanes. In fact, the first time we were on a one-way street. In both instances, we were able to cruise over to a parking space before the car completely stopped avoiding a rear-end collision. Once we got in the space, we turned the car off and back on but it would not go forward or backward. We sat for 30 minutes or so, started it up and was able to get it home. …”
