What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The contact stated that while starting the vehicle, the contact noticed that the Diesel Exhaust Fluid (DEF) warning light was illuminated. The vehicle was taken to the dealer where it was diagnosed and determined that the Diesel Exhaust Fluid (DEF) tank had failed and needed to be replaced.
We have a 2019 motorhome on a 2018 Mercedes Sprinter chassis. We are concerned about the wheel speed sensor failing. Three out of 4 sensors have already failed and been replaced on ours and Mercedes will not replace the 4th sensor until it fails.
There was no warning light illuminated. As the odor persisted, the contactâs eyes started burning and the contact also started having a headache. The contact inspected the vehicle and discovered that acid had leaked from the battery due to internal pressure inside the battery.
The contact stated that while operating the vehicle, the ABS, check engine, and cruise control warning lights illuminated. The cause of the failure was not yet determined.
This vehicle was sold to us new with the manufacturer's window sticker stating it was equipped with a Tire Pressure Monitoring System (TPMS) as a Standard Accessory - Safety/Cargo Protection. The provided owner's manual describes the TPMS system and the low tire pressure warning lamp indicator on the dash.
The contact received a recall notification for NHTSA Campaign Numbers: 20V663000 (Steering) and 21V042000 (Electronic Stability Control) however, the dealer informed the contact that the part for the recall repair was not yet available.
