Faulty electronics are a problem. Ever taken an item into a repair
outfit and had them say "not repairable"? They LIE. They just can't
be bothered. All electronics are composed of readily-available
components. Any competent electronics technician can fix them easily.
As I am having the experience of right now... I just happen to know
such a tech, who has repaired an "unrepairable" Mac power supply (dry
joint and faulty coil) and a turbo-timer (dry joints) and is fixing a
Sony Hi8 Camcorder, Olympus & Sony digital cameras. Car electronics
are no different.

Never heard of Toyotas spitting transmissions except after say
600,000km of hard use.

You should have seen the trouble my brother-in-law in Calgary had
with his Mazda MPV. It had an intermittent fault with the management
computer... when the engine was hot (going uphill in the Rockies;
very rarely in town) it would start to stutter, to the point where it
just couldn't make it up grades. It would never do this when he
showed it to mechanics... so they never fixed it. FINALLY, after over
a year of this, it DID do it, and the computer was replaced under the
used-car warranty.
