“Went in to have the spark plugs and 2 coils(cylinders 1 & 2) started shaking, knocking and smoking at the time I picked it up. Check engine light is on and hasn't gone off. The mechanic I take the vehicle to says it is a problem with this model car, trying to determine this, since he stated it is now my head gasket that needs replacing.”

NHTSA complaint #11180311, filed 2019-02, 1 miles

“While driving my 2011 Prius intermittently changes from drive to neutral. The car continues to roll but slows down. A warning comes up on the screen that the car is in neutral. I can pop the gearshift into drive and it seems fine, and may or may not behave the same way again. This has occurred on the freeway as well as on city streets. There does not seem to be any correlation to acceleration or deceleration or to movement (turns or changing lanes). I have taken it to the dealer who states that the systems check out fine and they were not able to duplicate the problem. …”

“Car stalled pulling into traffic. Took about 15 sec to restart. No diagnostic lights lit up on dash. Car lost power last month and engine light went on and engine could not be restarted.had to be towed to dealership. It replaced valve assembly for vacuum and reprogrammed PCM. However, that issue was preceded by a creep of diagnostic lights (course of 1 hour), from check oil to check engine, and then it completely shut down.”
