2020 Coachmen Prism

This Coachmen Prism 2150CB motorhome, built on a 2018 Mercedes Sprinter 3500 chassis, is now going back to the dealer a third time for the same problem. First time, rear wheel speed sensors were replaced while in for other service as a part of a recall. No big deal. But apparently the issue is not isolated to rear wheel speed sensors. At 11k miles, 500 miles from home, another wheel speed sensor went out, this time the left front. Now, at 14k miles, 1500 miles from home, the right front wheel sensor went out. When this occurs, the following systems do not work: ABS, ESP, cruise control. Why were ALL wheel speed sensors not included in the recall?

As per recall 23V100. Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Sprinter (907 platform) vehicles, the fuse layout of the interior blower motor might not meet the requirements for prolonged operation at the highest blower setting. Influenced by certain premises, such as ambient and assembly space temperatures as well as usage, this could lead to an increase of the transitional resistance between fuse and fuse holder and thus, to a limit-exceeding heat development in the area of the fuse holder. Consequently, a risk of fire during operation and a risk of injury cannot be ruled out.

According to the Interim Recall Notice Received by Mercedes-Benz concerning 22V796: "Mercedes-Benz AG has determined that on certain Sprinter vehicles, a component of the park lock system might wear extraordinarily due to specific driver parking practices and impair safe parking of the vehicle. If the vehicle is not properly secured in accordance with parking instructions in the operator's manual (including usage of the parking brake), it cannot be ruled out that the vehicle might roll away from its parked position under certain circumstances. Thus, the risk of an accident could increase. The driver will not receive a warning due to the nature of the failure mechanism. It is important that the driver ensures that the manual parking brake is engaged to adequately secure the vehicle against rolling away. Additionally, the parking level "P" is only to be inserted when the vehicle is completely stationary. The customer can find precise information on the parking process and on correct vehicle securing in their operator manual. Owners who notice any issues with the automatic transmission park lock function may contact their nearest Mercedes-Benz service partner immediately and have an appointment arranged for the vehicle to be inspected."

*Notice* This was received by Mercedes-Benz Canada - This was a recall conducted in Canada by Mercedes-Benz. To Forest River's knowledge, only vehicles manufactured and shipped into Canada are affected. According to Mercedes-Benz AG Group (MBAG): Mercedes-Benz AG Group (MBAG) has determined that on certain MY 2019-2020 Sprinter vehicles with diesel engines, the control unit software may not meet OBD functionality specifications. In the potentially affected vehicles, several OBD diagnostics and functions of the engine control unit, transmission control unit, and dosing control unit might not meet OBD functionality specifications. In case of the described issue, there is no impact on emissions, safety or drivability. There are no specific precautions to be taken with respect to the subject issue until the corrective measures are implemented.

MBAG was notified of customer complaints claiming a van had "rolled away" after the driver had selected the Park ("P") gear position and P was displayed to the driver in the instrument cluster. MBAG confirmed that if the vehicle is not properly secured in accordance with the parking instructions in the vehicle Operator's Manual, in particular by always engaging the parking brake after shifting to P, the vehicle could roll from its parked position, which could increase the risk of a crash. Always secure the van in accordance with the instructions in the Operator's Manual.

Mercedes-Benz AG (MBAG), the manufacturer of Mercedes-Benz and Freightliner vans, has determined that the software of the MBUX multimedia system might not meet specifications. Under very specific conditions, the MBUX multimedia system might not start and the display might remain black, or could reboot unintentionally after 50 seconds of initial startup. Accordingly, the rearview camera image might not be displayed or the display might be interrupted which could increase a risk of a crash or injury.

Attached is the Final Notification from Mercedes-Benz. Mercedes-Benz AG has determined that on certain Mercedes-Benz Sprinter vehicles the retaining washer on the bolt connecting the brake pedal to its bearing block may loosen over time. If the retaining washer loosens, over time it could detach from the bolt. In the worst-case scenario and with ongoing use of the brake pedal, the bolt may slip out of the bearing block on one side. If this occurs, the brake light switch may become permanently activated, even when the brake pedal is not pressed. If the braking lights were permanently illuminated it would not be possible for following traffic to determine the intention of the vehicle, increasing the risk of a crash. As soon as the bolt has slipped out of the bearing block on one side, the driver may notice the brake pedal to feel as if it is moving in a circular formation when being depressed. Owners who notice any issues with the mount of brake pedal on bearing block may contact their nearest Mercedes-Benz service partner immediately and have an appointment arranged for the vehicle to be inspected.
