Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving out of a driveway, a car pulled near my car. At that time, the car was stationary. My wife heard the pre-collision warning. The the car completely shutoff or stalled. Turned off the car completely by turning the key. Then turned the car back on. Lucky there was no accident.”
NHTSA complaint #11384767, filed 2020-12, 59,000 miles“I was driving on the interstate the car lost all power. On the dash board it read inoperative see manual. The can would not move. I almost got kill in the traffic. On 02/23/2015 I was driving on the interstate again the same thing happen again. Each time I took the car to the dealer. I am afraid to drive this car because it is very dangerous.”
NHTSA complaint #10690263, filed 2015-02, 220 miles“The coolant pump fails after about only 48000 miles, which causes the engine overheated. I did my research online and found that many others who own a mercedes cla 250 had the same coolant pump problem at low mileages (less than 50000 miles). Thus, I doubt that this coolant pump failure is a defect that needs to be recalled for. My car is still with the dealership so I do not have a report/receipt from them stating the problem yet.”
NHTSA complaint #11229577, filed 2019-07, 48,000 miles“While driving the vehicle loses power and barely has any accelerations. The warning sign said inop see owners manual. I had to pull over, restart car then it was back to normal. This has happened twice at the exact same road. I was at a stop light, made a left turn, drove about half a mile then this started. This is very dangerous!”
NHTSA complaint #10610627, filed 2014-07, 7,000 miles“Right air bag malfunction error and check engine light for crank case. This is a very common problem that mercedes explained to me and also told me to check back for recalls because their vni system will probably show one”
