I suspect a lot of Toyotas problems have to do with the standards in their overseas factories not living up to those on Japan
My father has driven toyotas for 30 years without a single breakdown. I have had 2, I had trouble with one of them.
It had a sticky accelerator (which I never considered serious as it only ever happened at the start of a journey), the wipers stopped working one rainy day, the driver seat adjustment lever gave up with the seat stuck in reclined and one time the brake pads stuck to the cylinder when the car had wasn't driven for a month.
Interestingly it was the only one of the lot that sported a "Made in Britain" sticker.
