“Vehicle stalled while driving on a busy road creating a very dangerous situation. Could not put it in neutral to push it out of the road; it was partially in the road for over an hour. Had to have it towed to replace the fuel pump and fuel pump control unit. Found two recalls after the incident and was told by Cadillac that my VIN was excluded. 1. Fuel Pump Assembly Recall (N202314760 / NHTSA Campaign 20V639) Fuel Pump Power Control Module Recall (N252516900) Out of pocket expense was $1173.97”Owner report · Fuel/Propulsion System · Jun 2026
“at 60,740 miles, "Steering Assist is Reduced Drive with Care" message appeared. Under warranty, but dealership booked for 2 months. Error went away. After powertrain warranty expires (70,000 miles), message constantly appears, and coolant thermostat display is BLANK. Results in excess fan usage (lowering fuel consumption), reduced steering assist, aggravation, check engine light. This issue has developed while under warranty, for a practically new car. Unacceptable. An extended warranty should be in effect for model 2020 as well.”Owner report · Power Train · Jan 2026
“Vehicle has a known condition with many same year make and model that could cause the engine coolant thermostat to open at a lower temperature than intended. This condition has occurred.

The engine cooling fans also run after the engine is switched off. A recent bulletin has been posted to the 2021 Cadillac XT6 but is present in our 2020 as well. Upon calling the dealer our VIN was not on said recall/bulletin.”Owner report · Unknown Or Other · Dec 2025
