Hi. Consulted mechanics at 3 Lexus dealers, and no one had ever heard of this problem. It occurred on and off for 3 weeks and then disappeared.
2007 RX350, running fine. Then, while driving, I shifted from D to P, and the engine just stopped. I was able to immediately restart with no problems, drove and shifted many times, then shifted from R to D after backing up, and the engine just stopped again. Once again, I was able to immediately restart with no problem. When the engine cut off, the check engine and VAT lights came on.
This occurred for 3 weeks--sometimes 1x/day; sometimes 5x/day; sometimes R to P; D to R, D to P, etc. . There was never a clear pattern in terms of frequency, time of day, weather or the gear I started in or shifted to.
Then, after 3 weeks of this irregular problem, it entirely disappeared: I've now been driving for a month and shifting gears with nothing unusual happening. But, there is obviously a problem that should be attended to, but what is the problems? Any thoughts about this would be much appreciated.
Neil
