Example complaints

“I hit a bear in montana in my 2017 mercedes C300 at 86mph and destroyed the front of my car. The seatbelts deployed and wrenched us into our seats and smoke came out of the front air vents but the airbags did not go off. On the dash the vehicles stated that the airbags in all 4 zones in the car malfunctioned and service is required. Mercedes is stating that the light is from a seatbelt error code but the dash did not say anything about srs or seatbelts. I do not want to put my family back in the car and do not feel it should be repaired. …”
NHTSA complaint #11112163, filed 2018-07, 17,000 miles“While driving the care, I noticed the seat belt light remained on despite being buckled and the passenger air was not set despite my wife sitting in the seat. I found this odd, contacted the dealership for service and researched if the car had a recall...this car did have a recall and was sold while in active recall status. Federal law explicitly prohibits dealerships from selling a new car if a pending recall hasn't been performed. As, a result, I no longer want this car because the car should not have been sold until the recall was prepared. …”
