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. When this sensor fails it affects the ABS brakes and the braking distance is increased which can cause an accident. The cruise control is also affected and could increase speed on its own. The ESP can also be affected and can increase the risk of skidding and accidents. We have spoken to many other motorhome owners with the same chassis and they have also had problems with the sensors. Mercedes is aware of this problem and we feel they should…

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. It was not until our first flat tire after 2.5 years and 24000 miles, that we learned our vehicle does NOT have TPMS OR a low tire pressure warning lamp. Another motorist flagged us down as it was the inside dually tire that deflated and delaminated. Luckily we learned of the deflated inner tire before the outer tire also had issues because of the extra load placed on it. We have since…

On or about April 27, 2021 the driver's side rear taillight assembly randomly fell off between Phoenix and Tucson, Arizona on Interstate 10. The assembly is large, containing the taillight, brake light, turn signal light and back-up light. It could have (and may have) hit another vehicle or at least caused it/them to engage in a dangerous turning maneuver to avoid hitting the large assembly while on the freeway. In addition, the RV was then rendered unsafe and in violation of the laws of virtually every state, as well as federal regulations, due to lacking the required lighting assembly. This has also happened to another RV unit from the same manufacturer (Regency). The driver's side…
