Example complaints

Air bags: “Takata recall we have been notified in february of 2016 and it is now november of 2016 and still no parts. We can't sell the car because I don't want to pass the problem onto another person and mercedes won't give us a loaner so we have a potential risk. Telling us that it is a minimal risk doesn't help. This is beyond irresponsible! Can you please advise”

NHTSA complaint #10925705, filed 2016-11, 95,000 miles

Brakes: “I called the Dealership to schedule the appointment. They told me they have no appointment available for next 3 weeks and even I wait for that long they will not be able to provide me a loaner car. The total job time is 4-6hrs I am not willing to wait that long. This dealership was not helpful at all in-spite of this is a very serious safety concern. STOP DRIVE REMEDY. Worst Customer Service for the brand we have.”

NHTSA complaint #11515770, filed 2023-04

Engine: “The contact owns a 2010 Mercedes-Benz R350. While driving 20 MPH, the vehicle stalled without warning. The contact was able to restart the vehicle, but the failure recurred. The vehicle was towed to the dealer to be diagnosed. The contact was informed that a valve in the engine failed. The vehicle was repaired. The manufacturer was notified of the failure. The approximate failure mileage was 72,000.”

NHTSA complaint #10823136, filed 2016-01, 72,000 miles

Suspension: “I had just arrived at church and noticed the car leaning to the right side. I ignored it at first thinking maybe the driveway was uneven. When I got ready to leave my boyfriend pointed it out to me that the truck was leaning to the right. I took it to a shop to be checked out and they couldn't figure it out. There was no message regarding anything on the message board except service c was so many miles overdue. Called mercedes and they told me rear air bag. Cost would be around $1600. Cant understand why the dealer would not put a recall fir this problem.”
