The last time I rode on your car I noticed the following:

A squeeking and creaking in the front end when hitting bumps.

An erratic idle, it hunts up and down sometimes after a long drive, and there feels like a random miss.

The transmission shifts funny sometimes, like it waits a while before getting into second, then abruptly catches the gear, sort of lurches.

There is a flicker in the instrument panel, like someone turning the dimmer up and down rapidly, only happens after driving at night for a while.

.....

This caused $10,000 in free warranty work to be done on our e320 which seemed to be running fine with 100 miles left on warranty..

get my drift?
