2022 Coachmen Galleria

High altitude power loss. At around 8000' elevation, 60 degrees F. Engine was turned off for around 3 hours, started normally, idle normal, shifted into reverse and there was no power. It barely crept out of level parking place with accelerator floored. Engine continued to run smoothly but no power. I was half in the parking spot, half in the street and couldn't move forward or reverse. No warning lights prior / during / or after the problem. Approximately 4500 miles on van. Note - vehicle put into 4x4 low range in attempt to use the extra gearing to move back into parking lot out of the street - this worked at a very slow pace. After multiple attempts to move, about 5 minutes total - it started making normal power again. Minor versions of this have occurred several times at 5000-10000' in Colorado. Van ran normally once back to lower altitudes.

The battery boost cable is connected to a chassis lug provided by Mercedes. The 12V wiring will be routed to a new lug.

According to a Furrion TSB "TB-220919": Irregular cooling performance has been reported on the identified refrigerators. The refrigerator compressor has been found to stop working and requires a “hard reset” by disconnecting power to reset cooling operation. On occasion, disconnecting power does not reset operation and the refrigerator requires service replacement of the control boards. This TSB may not be applicable for some vehicles.

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."

According to Mercedes-Benz Recall 22V360: “The communication module's SIM card could become disabled and prevent a connection with a mobile phone network. In this case, the digital owner's manual as well as the automatic eCall function would not be available, which could preclude or delay the arrival of emergency responders. This could increase the risk of an injury following an emergency event.”

Mercedes-Benz AG (MBAG) Recall 21V131, the manufacturer of Mercedes-Benz Sprinter vans, has determined that the torsion bar on certain Sprinter vehicles was not assembled to the torsion bar linkage by the component supplier in accordance with design specifications. The shim on the torsion bar was incorrectly installed between the nut and the torsion bar, rather than between the ball stud and the torsion bar. Due to the incorrect assembly, the torsion bar may not meet operational strength requirements. Settling effects may occur between the journal flange and the torsion bar. These effects might reduce the bolt preload at the connection, which could increase fatigue on the journal and lead to a fatigue fracture of the journal, which could increase the risk of a crash.
