After the car sits for three or more days, brakes locks up. It takes lots of power to get the brakes to release. It’s a safety concern as the car is parked in the garage with not enough room to maneuver. We never had any car which locks the brakes in this manner. Took it to MB dealer and they say it’s the way brakes are designed. A complete nonsense.
NHTSA complaint 11470644Mercedes Benz issued a recall (Manufacturer Recall Number 2021060021; NHTSA Recall Number 21V354) in May 2021. The recall affects my vehicle's MBUX multimedia system, most importantly, the backup camera, which may fail while in use if this issue is not remedied. I was advised of the recall by them in July 2021. To date they have failed to remedy this safety recall. I have contacted Mercedes Benz several times (most recently on 03/21/2022) and they are unable or unwilling to provide a date when this safety issue will be remedied.
NHTSA complaint 11457978The contact owns a 2021 Mercedes-Benz E450. The contact stated that the vehicle speed control was always inadvertently activated, which caused the vehicle to decelerate automatically. The failure nearly caused a collision. The dealer was made aware of the failure and referred the contact to the manufacturer. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and informed the contact that they would call back. The failure mileage was approximately 1,000.
NHTSA complaint 11445405The 48 volt battery on this mild hybrid vehicle failed and the car was unable to be started on May 3, 2021, with 196 miles on the odometer, a mere 15 days after delivery. It had to be taken by flatbed to the dealer where ultimately the 48 volt battery was replaced. Then again on June 5, 2021, the car was again unable to be started, with a mere 735 miles on the odometer. Again, the car had to be taken by flatbed to the dealer, where ultimately the 48 volt battery was replaced a second time. While both failures, fortunately, happened while the vehicle was at home, the could have happened on the highway, in the middle of nowhere in bad weather conditions, or anywhere. I have had to cancel a cross-country drive for fear that, once again, the 48 volt battery will fail, leaving us stranded anywhere or, worse yet, in the middle of a highway.
NHTSA complaint 1144171248Volt battery failed after three months and just 3,400 miles. I understand this is a recurring problem with Mercedes. Car had to be towed as the vehicle was totally inoperable due to battery malfunction. It took more than three weeks for Mercedes to provide a replacement battery. From what I have read, there is a strong likelihood that the battery will fail again.
NHTSA complaint 11427592I BOUGHT THIS CAR ON 12/12/2021 AND TWO WEEKS AFTER THAT, THE CAR HAD WARNING MESSAGE ON DASHBOARD "COOLANT TOO HOT, STOP THE VEHICLE" ON THE HIGHWAY -NJ TUNPIKE. IT STARTED SLOWING DOWN ON ITS OWN TO BELOW 20MPH, NEARLY KILLED ME WHILE I TRIED TO PULL IT OVER. THEN THE DEALER SERVICE SAID IT HAD DEFECTIVE WATER PUMP. THEN LAST WEEK 4/13/21 - 4 MONTH,ABOUT 2800 MILEGE ON IT, IT WOULDN'T START AT ALL., JUMP START DIDN'T EVEN WORK. SO I WAS STRANDED AGAIN IN THE MIDDLE OF THE NIGHT. IT GOT TOWED AND THEY SAID IT HAD DEFECTIVE BATTERY. SO HOW MANY DEFECTIVE PARTS THIS CAR HAS. IT WILL KEEP BREAKING DOWN AND THREATEN MY LIFE ON THE HIGHWAY WHERE I COMMUTE EVERY DAY IN THE NIGHT TIME. THEY SHOULD TAKE THIS CAR BACK AND REPLACE BUT THE DEALER REFUSED BECAUSE IT HAD PROBLEMS ON DIFFERENT PARTS AND FIXED. BUT THIS VEHICLE IS PIECE OF JUNK AND A RISK TO NOT ONLY MY LIFE BUT ALSO O THER DRIVERS ON THE HIGHWAY BECAUSE IT DOES THINGS ON ITS OWN WAY, I HAD NO CONTROL OVER THE CAR AT ALL.
