Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“since I am chemically sensitive and they had sprayed so much cleaner in this vehicle that when my husband got it home he took vinegar and cleaned it out many times and then he took it to someone to have them do the floor over so the plastic smell wouldn't stink so bad for me. It had to be there for a couple weeks or this I'm sure would have showed up much sooner. …”

NHTSA complaint #11560427, filed 2023-12

“I had the same issues as identified in a current recall entitled: Model 907 Sprinter. Model Year 2019-2022 Update Instrument Cluster Software. In my case the instrument cluster remained non-functional upon vehicle start-up exactly like the recall with an added problem of the ignition push button would not shut off the vehicle. I was left with a vehicle I could not shut off without an operational instrument cluster. …”

NHTSA complaint #11691714, filed 2025-10

“My vehicle is activating “crosswind assist” and applying the brakes automatically, unilaterally, and abruptly while traveling at speeds over 40 mph on the highway, even when conditions are NOT windy. It seems that the sensor is overactive in detecting wind. I have taken it to the Mercedes dealer and they have stated they found no problems with the ESP sensors and state that the vehicle is responding to perceived wind conditions/instability normally and as it should. However, this was NOT like this for the first two years I drove the vehicle. …”

NHTSA complaint #11646502, filed 2025-03

“My 2021 Mercedes Benz Sprinter van came equipped with Lane Keeping Assistance and Automatic Braking features that are on by default every time the engine is started. There is no way for an owner or a Mercedes Benz technician to have the safety feature set to remain off until the driver chooses to engage the features. I believe this is a safety hazard, as we experienced 2 incidents on a recent trip. 1. Lane Keeping Assistance took over the vehicle without warning from a slight wind gust, and almost caused us to get in an accident. …”

NHTSA complaint #11437425, filed 2021-10

“The contact owns a 2021 Mercedes-Benz Sprinter 2500. The contact stated while driving on the highway at 65 MPH, there was construction that had directed traffic to the right side of the road. The contact stated that while driving past the construction site, the active lane departure assist warning light illuminated on the instrument panel which caused the steering wheel to shake and the brakes to lock-up. The vehicle independently began to steer out of the lane and into another lane which almost caused a crash. …”
