From NYT:
On a hot summer trip to Cape Cod, the Mills family minivan did a peculiar thing. After an hour on the road, it began to bake the children. Mom and Dad were cool and comfortable up front, but heat was blasting into the rear of the van and it could not be turned off.
The minivan’s problem was unusual only in the specific form it took. Owners across the country and around the globe have posted anguished cries to Internet forums about electronic gremlins that stop windows from rolling all the way up, that unexpectedly dim the interior lights, that drain batteries or that make engines sputter. While most automakers have had problems, quality rankings for some – particularly technology-intensive German luxury brands renowned for engineering – have plunged.
