The vehicle was involved in a collision on January 26, 2023. I am not claiming that the computer malfunction caused that collision. After the collision, while I continued operating the vehicle, problems developed with the vehicleâs computer, electronic control system, and instrument cluster. The instrument display could become dark or unavailable, and a CHECK ENGINE warning was present. This prevented reliable access to important information such as vehicle speed, warnings, and operating status. I brought the vehicle to a repair facility expecting a complete inspection and repair. An insurance inspector was expected to inspect and document the vehicle before repairs, but the inspector did…

Front crash with no airbag deployment and no emergency braking. Currently at The Metal Shop in Warm Springs Va. Told by insurance it is totaled. Sustained mild concussion from head trauma. Head hit steering wheel. I notice many Sprinters for sale for parts after similar front end collisions. No warning lights.

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.

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 wasnât) 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…

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.

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.
