Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“After starting up the car (but during ignition, the key slipped in my fingers causing a missed start, I therefore had to turn the key again to get engine to turn over.) and driving from my driveway, there was a complete failure of the steering assist which caused extremely difficult steering/cornering. I pulled over, thinking it had to do with the missed start, turned off the engine and restarted it; still no power assist. Took it to the dealer, they were able to do a computer reset which restored power assist, but told me they could not say if or when it would happen again. …”
