2021 CADILLAC XT6 Complaints and Recall Information
The 2021 CADILLAC XT6 has 6 complaints and 3 recalls filed with NHTSA. Owners most frequently report issues with the rearview cameras failing or showing warning messages. Additional complaints include instrument cluster display problems and coolant fan operation after shutdown.
Common Issues- Steering assist warning. Dash displays "Steering Assist Reduced" message upon startup alongside missing engine temperature readout on the instrument cluster.
- Coolant fan operation. The coolant fan continues to run at full speed for several minutes after the vehicle is turned off.
- Rearview camera failure. Rear and front vision cameras abruptly stop working with no warning lights initially, often displaying error messages like "Park Assist Block" or dashboard icons showing camera failure.
- Camera system malfunction. Issues persist despite cable replacements related to a recall, with some vehicles needing video processing control module replacement due to reprogramming failures.
- Dealer recall confusion. Some units were sold without addressing the camera cable recall properly, leading to unresolved camera system failures.
The XT6 has three recalls affecting multiple systems including vision cameras and fuel delivery.
Recalls- Rearview camera coaxial cables. (NHTSA Recall 22V709000) Affects 95,231 vehicles. Coaxial cable connectors for the rearview camera may be crimped improperly, causing intermittent or complete failure of the camera. This reduces rear visibility and increases crash risk. Dealers replace the coaxial cables free of charge.
- Fuel supply lines. (NHTSA Recall 21V422000) Affects 572 vehicles. Fuel supply lines may be improperly attached and seated, which could loosen or separate, causing fuel leaks and fire risk. Dealers inspect and replace lines as needed at no cost to owners.
Owners with repeated repairs or unresolved safety issues related to recalls or persistent defects may have rights under their state lemon law. Those affected should consider consulting legal resources to understand their options.

1)The display on dash reads upon start up, “Steering Assist Reduced”. 2)There is no Engine temperature readout displayed on cluster. 3)When the vehicle is turned off, the coolant fan stays running for a few minutes at full speed. All of these issues are correlated. Also, many XT5’s & XT6’s have had this issue in the past.
