Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Vehicle shut down in the middle of a 6-lane divided roadway. The check engine light was lit and the car would not restart. The dealership indicates that the computer or PCM failed. The part was backordered nationally. They tried removing a computer from another TSX on the lot, but it failed due to compatibility issues. Apparently, this part is unique to each vehicle. After another week, the custom-built computer still has not arrived and I'm at the point where the car will have soon spent more time in the shop than in my driveway.”
