ELECTRICAL SYSTEM07/14/2026
Frequently, when I started the car, the instrument cluster's monochrome display will stay blank/black or display completely corrupted garbage - unreadable bit and pieces. I wasn't able to read essential info like level of drive gear and fuel level etc. Often when this happens, the physical speedometer pointers won't settle on accurate current speed level, but keep cycling: from 0 spin to some value and then reset back to 0 and spin to some value ... This makes driving risky as I am not able to see accurate driving speed!

Almost immediately after I got my Van the Aux Balmar Alternator installed by THOR had to be replaced and was not functional. I tried to get it repaired by two warranty repair centers in Colorado and neither one could repair the Alternator or get it to charge the lithium battery that was also new. Thor told me that they would have specialist look at it when I brought it into Blue Compass of Wheatridge and they told me they had fixed the issue but it still will not charge battery even after 17 hours of driving.
FORWARD COLLISION AVOIDANCE06/23/2026
Active distance assist inoperable, active brake assist functions limited, adaptive cruise control not working, lane keeping assist glitching. I was driving the vehicle home after purchase and the lane keeping assist was glitching, it was actively pulling the wheel to the left, like I was over the fog line (I wasn’t) and it was hard braking, Making driving very unsafe. I slowed down and got off at the next exit at a gas station to figure out what was happening. I put the vehicle in park and consulted the manual. I tried to turn off and back on all the systems, through the menu, noting worked. I shut the vehicle off and cleaned the areas around the sensors and the windshield, like the manual suggests. I went in to start the vehicle, and the message “service required do not shift gears” came on the dash. It was stuck in Park. I tried to get a tow truck, but had to wait 4 days, in a gas station parking lot before a tow company with a big enough truck, and skids, (because it was stuck in park) could come on Wednesday May 27. I got it towed to a repair shop. It shows the Code P179A77 direct select redundancy malfunction, they couldn’t fix it. It needs Xentry level diagnostics. The intelligent Servo Module, or direct select module failed/won’t shift from park. There is a recall that wasn’t fixed, I got a carfax from the dealer saying that there were NO active recalls. The recall is to update an all service modules. Yes it’s available for inspection, but it’s stuck in Park at the repair shop that can’t fix it in Riverton Wyoming. I called Mercedes Benz, and tried to get help because the active recall should fix these problems. They would not help. They will not sell me the part and code it to the vehicle because it’s part of their theft deterrent system. This has cost me thousands in flights, hotels, and countless hours trying to figure it out. The nearest Mercedes Benz dealership is 270 miles away, and towing will break me.

Passenger side grab handle physically separated from the body of the vehicle. Inspection confirmed the separation was caused by the failure of the factory welds securing the handle.

STEERING01/13/2026
Power steering hose is too short from factory, mine came loose while driving and I lost power steering assist unexpectedly. In checking forums, this is an EXTREMELY common problem and has existed since at least 2018 - mine is a 2022.
LANE DEPARTURE10/13/2025
Hello. There is a Crosswind Assist feature on the van that is downright dangerous. When it engages it breaks and corrects the vehicle in a way that will result in an actual crash, worse than what the feature is intended to do. This could be a great feature if it didn’t cause more harm than good. It overcorrects. Almost caused me to hit another vehicle and run off the road.

The contact owns a 2024 Winnebago Revel RV built on a 2022 Mercedes-Benz Sprinter 2500 Chassis. The contact stated while the RV was idling, the heater was activated, and the contact's wife made him aware that there was an abnormal smoke odor. Additionally, the contact stated that while the RV was idling, the contact opened the mobile app and noticed that the Winnebago house battery was not charging. The contact also noticed the failure while driving. The RV was taken to the dealer, where the alternator was replaced twice; however, the failure persisted. The RV was taken to Coastal RV Center (6075 Savannah Hwy, Ravenel, SC 29470); where it was diagnosed and determined that the alternator needed to be replaced; however, the part was not available. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the part was not available. The failure mileage was approximately 600.

I have a 2022 Mercedes Sprinter with the M274 engine. At approximately 139,100 miles the check engine light came on and my driver was stranded on [XXX] . I took the vehicle to Mercedes-Benz of Kansas City South for diagnosis. I was told that the #4 piston cracked and scored the engine wall. I was quoted $23,820.12 to replace the engine long block. When I asked about trading the vehicle in, they offered me $2,000 for it if I was willing to purchase another vehicle from them. I did some research and there is currently a class-action lawsuit for this exact issue. In reading the comments of various class-action lawsuit websites, this seems to be a manufacturing issue that Mercedes knows about, but is doing nothing to fix the issue.

Charging issue with house battery side of class B camping van. It became somewhat apparent the system was not charging properly and quickly escalated to a high overcharge situation, followed by evidence of electrical short in smells and possible smoke in engine bay. The car was in for service for a month and a half. I am not sure the issue is completely resolved and Winnebago has been fairly unresponsive when asked questions afterwards. This issue could cause a fire. There are multiple units with similar issues. Ultimately the secondary alternator was replaced, and a recall kit applied. I am not sure what the specific kit entailed. The repair was done at Johnson RV in Sandy Oregon
UNKNOWN OR OTHER,LANE DEPARTURE01/04/2025
My van has a "cross wind assistance" feature that can not be turned off. Apparently it helps to keep the vehicle in the lane during cross wind situation, I found it to be way too aggressive and turning itself for no apparent reason. I find it that while it may be helpful in some situations it certainly does more harm than good.
ELECTRICAL SYSTEM,AIR BAGS11/25/2024
On [XXX], I purchased a new 2022 Mercedes Benz Winnebago Adventure Wagon (“RV”) from La Mesa RV located in Phoenix, AZ. Prior to purchase, while doing research online, it came to my attention that there was an NHTSA Safety Recall for this particular year/model that affected wires under the seat and potential Airbag deployment. (NHTSA Part 573 Safety Recall Report #24V-318). Once I learned of the safety recall, I contacted the dealer on September 21 to determine if this particular vehicle was part of the recall and/or if it has been repaired. On September 23, a representative from La Mesa RV contacted me and assured me this specific vehicle was not part of the recall and does not require a repair. After purchasing the RV, I contacted Winnebago directly to inquire about the warranty and any pending recalls, specifically NHTSA #24V-318. The representative from Winnebago confirmed that this specific RV (verified by VIN) was in fact part of the recall and should have been repaired by the dealer prior to sale. On November 6, 2024, I emailed the manager at La Mesa RV to report the misinformation provided by them and requesting immediate remedy. The manager nor any representative from La Mesa RV responded to address this issue. La Mesa RV appeared to ignore the safety recall and sold a new vehicle to me without repairing a known issue. They have not offered any remedy or correction. Dealer contact info: La Mesa RV, 7525 W. McDowell Rd, Phoenix, AZ 85035. Thank you for your attention to this matter.
