“On friday 7/17/2020 aroundnoon, I wasdriving mymb glb that was bought lessthan90 days ago when suddenly the dashboard went blank. I could not see speed, gas gages or any other safety features that would be on the dash. I was basically blinded. I called mercedes 911 after stopping the car. We tried to factory reset the computer on advice from tech via the phone. This had no impact on the screen. The mb rep did not offer roadside assist. I had to drive over 25 miles with no dashboard to gage my speed, gas or safety lights. I had no choice as no help was coming to get me. …”

“Since the beginning of the vehicle purchase, we heard fine metal rattling sound on the front driver side tire. Had it checked with the dealer and they recommended no repair. Now driven about 35K miles and started very loud metal scratching sound when wheels turned to right. Inspection showed bent brake cover that was wearing tire uneven. Dealer claims that we went over a large bump that bent the brake cover but no such thing happened and this location is where we have been hearing this fine rattling since buying new. …”

“My car has a recall from May 2021, I purchased my car Oct 2022. When asked about the recall the finance manger at Mercedes Benz of South San Francisco, Rapheal Chin stated it was no open recalls on the car. When I pointed out the repair order didn’t match the car fax, it was explained by the salesman that it was completed. But NHTSA says that it was not fixed. When trying to get it fixed my car sat at the dealership for 8 days with no understanding of how to fix my car. This is clear neglect on the manufacturer and is causing me grief! …”

“1) As I was driving on the highway, the TRANSMISSION went into neutral. An error message on the display said that there was a transmission issue and to stop the car. 2) Fortunately, I was able to safely pull off the road without incident. However, there are many places that I wouldn't have been able to do that (for example, on the Sagamore Bridge which I use daily). I could not accelerate and I was rapidly slowing down. I could have been rear-ended by one of the many tractor trailers that were on the road at the time as they are not able to slow down as quickly as a car. …”

“My vehicle have bad smell coming from air conditioner vents. Took to the dealer two time in one month to find out the cause. It smells like mold inside the evaporator coil. Dealer cleaned with some kind of sanitizer to kill the mold. But the smell keep coming back over and over. Vehicle has only 3900 miles on it.”
