My vehicle stalls (won't accelerate and rough idle) forcing you to roll off the highway without warning. This has happened multiple times while in cruise control going up steep hills. It shows engine misfire and check engine. I took it to the dealer multiple times and it was determined to be bad gas. I and my insurance company paid for this dealer (hatch Toyota show low az) for complete clean and replacement of the entire fuel system. Now 5 months later it is doing it again. The safety issue is the stalling in the middle of the highway where there is no way to get out of the way of traffic. I made sure I bought good gas by paying extra money at a new chevron gas station with new in ground tanks. But dealer claims bad gas again. That is a separate issue.
Vehicle will not hold 6th gear while in cruise control. Vehicle will suddenly down shift to 5th and sometimes 4th. This makes the vehicle surge forward abruptly.
