I have had other problems with my RX, where it would refuse to start and kept displaying shift to "P" when starting even though the car was in park. And then would start (ready) all of a sudden. I had to call Lexus road side assitance twice and cancel the call because after a 30 min wait or more the car became driveable again. I took it to the dealer every time and they checked the car thoroughly, kept it for few days, and came back negative. Every time they said, "we could not find any problems with the vehicle or any fault codes. Never have we heard of such a problem either." And then when it happened the next time I luckily had my camera, so I took a full video footage of the display, the shifter position and my attempts to start it etc. and played it to the service guys. They again kept the car and kept telling me "we believe you but we can't find the problem". Then I suggested them to test the auxillary battery (12V) and voila, it had a dead cell! They replaced it under warranty, but fitted it with a bigger battery whcih does not fit the battery plate. The new batteries have a slighlty bigger form factor.
Honestly I have never owend any of those vehicles you mentioned and therefore can not comment. I guess you have valid reasons to say so. But, if at all, poor design and quality of other makes will not make Toyotas any better, will it? A sampling rate of 20 minutes on a tire pressure monitoring system simply tells me that whoever engineer conceived or designed it lacks common sense, not just engineering skills, won't you agree?
