ESP light went on several times. Would go off only when car shut off then restarted. Took it to MBZ dealer and they said they couldn't find it on the computer. Charged me $3,000+ to fix other items, then within one week it happended again along with the suspension warning light. Now it's been in the shop and they want to charge me another $3,000 + to fix what they were supposed to fix in the first place.
