Cadillac XT6 Engine problems by year

The contact owns a 2020 Cadillac XT6. The contact stated that while idling at a stoplight, the vehicle experienced a loss of motive power. The contact stated that multiple attempts were required to restart the vehicle. During the failure, the transmission failed to shift into neutral, and the check engine warning light illuminated. The contact researched and discovered NHTSA Campaign Number: 20V639000 (Fuel System, Gasoline) and associated the failure with the recall. The vehicle was taken to the dealer; however,...

I noticed a water sloshing sound behind the dash when first starting out for about a month. I didn't get any warning lights or notice anything leaking under the car but when I checked under the hood the coolant reservoir was empty. I made appointment at GM dealership and they found I had a leak along the side seam of my radiator. The car only has 61k miles! I found online that GM has noted a structural design issue in my XT6. The radiators were engineered with tight thermal break tabs. If they stay locked in place...

DTC P0128 engine coolant thermostat to open at a lower temperature than intended. The Check Engine Light appeared, a Steering warning appeared on my information screen, and the engine cooling fan continued to run excessively after turning off. I understand there is a Special Coverage N252508350 for this exact issue, however, GM is refusing to cover the cost of repairs.

I was driving in a highway going at highway speed and the car suddenly just shut off and all the alert lights were reflected at that time the car was not responding completely, shut off, then within seconds after the lights flashed it started on it's own. It was the first time this happened. I was concerned that the car would not respond and maybe could have cost an accident.

The contact owns a 2021 Cadillac XT6. The contact stated that while sitting inside the vehicle, the vehicle felt unbalanced. Upon inspection, the contact noticed that the H-pipe was leaning more to the right side. The H-pipe was not centered as intended. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The contact stated that in the past, while the vehicle was serviced, no one had noticed that the H-pipe was off-center. The manufacturer was not notified of the failure. The failure mileage was approximately 37,000.

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. As a result the Malfunction Indicator Lamp (Check Engine Light) illuminates and a diagnostic trouble code is set and "steering assistance reduced" appear. 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.

The Radiator is not functioning, confirmed by a mechanic at a dealership. An engine light did appear to notify me of the problem, however the car has been kept in great condition without accident or cause for the radiator to stop functioning in such a young vehicle.

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.

I purchased the new 2022 Cadillac XT6 in June 2022. The first week I owned the vehicle, I was driving and I lost power and the vehicle came to a stop. The mileage on the vehicle was 134 miles. The Cadillac dealer indicated there was a failure in the engine and power train that caused the engine to lock up. The dealer/GM replaced the engine in the new car with 134 miles on the vehicle. Attached is the service report from the Cadillac dealer that replaced the engine

The contact owns a 2020 Cadillac XT6. The contact stated while driving at 35 MPH, the vehicle lost power. The vehicle was restarted from the Cadillac App via phone. The contact stated that during the second failure " The steering assist is reduced drive with care" warning message and the check engine warning light illuminated. The contact stated she called On-Star where she was informed the tire pressure, the engine, and the transmission needed attention. The vehicle was towed to a dealer by AAA where it was...

Car started and ran at idle for 5 minutes. 10 minutes later when attempting to restart, the engine churned for several seconds then ran for about 2 seconds and cut out. "Press to Start" button remained showing green and would not respond to being pressed. The car was stationary in my garage; this would have been extremely dangerous if it happened on the highway. It seems to be a complete failure of the fuel system on a 2021 model with under 27,000 miles

The contact owns a 2020 Cadillac XT6. The contact stated that while the vehicle was parked, the instrument panel went black. The vehicle was restarted, and the instrument panel lights illuminated but the vehicle began shaking from the driver's side. The check oil warning light was illuminated. Additionally, the contact stated that she felt heat coming from where her feet were located under the dashboard. The vehicle was taken to a dealer where it was diagnosed and determined the driver's speaker was inoperable due...

The vehicle's check engine light came on late afternoon and then started with a delayed turn over, but not actually starting thr following day. The vehicle had to be towed to the dealership. The technician and service advisor commented immediately that it is likely the fuel pump control module. With the commentary about the likely cause was that this is a widespread issue among GM vehicles. Thankfully, the vehicle was at home when it stopped starting but the transition from check engine to stopping operation was almost immediate.

The vehicle was driven into low water and the belief is tha vehicles near this vehicle created a wake which caused the engine to die. The dealer that has the vehicle advised that another vehicle same make and model need an engine replaced. For both vehicles there was no water intrustion into the passanger compartment. The water did not even come up to doors. The engine is being replaced.

2020 Cadillac xt6 with all options and new vehicle with less than 400 miles, fuel gauge indicator hash marks that show the level of fuel on the fuel gauge intermittently stop working upon engine startup. Dealer has already checked computer codes and found no error codes. Dealer states they have reset computers several times to correct this issue. Dangerous driving without knowing how much fuel is really in the fuel tank.
