The contact owns a 2020 mercedes-benz glc300. The contact stated that upon driving through an intersection at 40 mph, another vehicle had run a stoplight. The contact swerved in an attempted to avoid the vehicle, however, she had hit the vehicle's rear driver side tire weld. The contact stated that the driver-side airbag did not deploy upon impact; however, the passenger-side airbag, where her mother was seated, did deploy. The mercedes-me app automatically called 911 and the contact initially declined medical attention at the time. A police report was filed. Due to the failure, the vehicle was towed to an independent mechanic. The next day, the contact was referred by her doctor to a hospital where they performed a cat scan and x-ray. The contact tested positive for covid-19 the following monday and believed it was as a result of the hospital visit. The manufacturer was notified of the failure and upon her own research, the contact discovered nhtsa campaign number: 21v354000(back over prevention, electrical system). The vehicle remained in the possession of the independent mechanic and had yet to be repaired. The failure mileage was unknown.
While driving under an overpass the breaks activated abruptly and unexpectedly.we where going about 35 miles per hour and if it wasn't for the seat belts we would of hit the windshield. Luckily no one was following us up close.. It happened twice at the same spot where there is a shadow from the overpass (at same time of day)
Driving along random traffic no pattern, automatic brake assist is temporarily not active , bright yellow wording, danger auto brake assist will not function at this time.
The vehicle wonders within the lane when mercedes distronic driver assistance is activated, particularly on gentle curves at highway speeds. It will hit lane bumps unless the driver actively steers away from the lane markings. The 2020 glc3004matichas been doing this since we purchased it new on january 2, 2020. Mercedes dealer has checked the vehicle and is now describing the vehicles behavior as normal. According to mercedes this is a new driver assistance package in the 2020 glc.it is a major safety hazard if the vehicle is not actively controlled by the driver at all times. This is not an assistance package as described by mercedes. We have driven older mercedes with the distronic system that stayed in the lane vs. The wondering. We do not take our hands off the steering wheel the vehicle does this on it's own prior to any warnings related to driver awareness or actions. This action by the vehicle when distronic is activated will cause serious life threatening accidents.
The sunroof of our car shattered by itself when we were driving on a city street. There was no projectile that caused the sunroof to shatter and the dealership was able to confirm that. But the dealership and the company are unable to say for certain why this happened and whether or not this will happen again. The incident caused glass to fall on all our passengers and the sound of the glass shattering during driving really scared us. We are concerned for our safety and even more concerned that mercedes is unable to diagnose why this happened and are not able to say for sure that it would not happen again.
Received safety recall from mercedes benz (nhtsa recall #21v058) and have tried to schedule with dealer on several opportunities to get the repairs completed and they continue stating they cannot perform the recall repairs
The audible tic-tok sound of the turn signal is way too soft.the sound is supposed to give one notice that the turn signal is on.it simply isn'tloud enough to provide that feedback.consequently i often find that i'm driving down the street having completed ahalf-turn ( one where it doesn't trigger a shut off) with my turn signal on for blocks before i notice that the turn blinker is still on.
I was driving and stopped car to make a turn waiting for incoming traffic to clear. When i went to accelerate after traffic cleared, the car would not go above 0.5 miles per hour. I made sure the gear had not shifted to neutral, it was on comfort drive. I changed to sports drive and the car still would not accelerate above 0.5 miles. I was now stuck in the middle of intersection with incoming traffic, so i tried to reverse. The car reversed no faster than 0.5 miles per hour. I turned car off and back on, and acceleration then worked. Very scary. I was lucky incoming traffic avoided me. Big safety hazard. Dealership so far has not been able to replicate the issue, but i read other blogs where people experienced a similar event.
Received a safety recall notice to have corrective action taken to the communication module to communicate the correct vehicle's location for the emergency call system; however, local dealer says they cannot resolve.copy of recall notice attached - see below.
