NHTSA Complaint #11612725 — 2002 MERCEDES BENZ C320

Battery drains after being parked overnight, 58,000 miles, dealer maintained since new. Driven by a little old lady until I bought it. Took it to the dealer and they replaced one of the seat modules. Soon afterward, the problem recurred. Took it back to the dealer and they said it was a defective fuse box and replaced it for $650. Went to pick up the car and the battery was dead again. After some complaining, they refunded the bill. They looked at it again and said the problem was somewhere in the dashboard and it would cost $2300 just to take it apart and look for a bad module. They offered $2300 trade in toward a new or CPO car, and said my car would be sent to the crusher. I took the car back and installed a remote operated battery cutoff, and have been driving it ever since. Other than disturbing the engine computer, it's been running well for three years and 20,000 miles. Lovely car otherwise.
