2017 Cadillac XT5 Complaints

The contact owns a 2017 Cadillac XT5. The contact stated that while her husband was driving at approximately 50 MPH, the vehicle lost power steering functionality. The contact stated that the power steering assist message was displayed. The vehicle was taken to the local dealer where it was diagnosed and determined that the power steering assist had failed. The contact was informed that the part was on backorder. The vehicle was not diagnosed or repaired. The manufacturer was contacted. The failure mileage was approximately 78,146.

The power assist steering goes out and you have to manually try to steer the car the part that has to be replaced is the power assist steering module which is located in the steering assembly I have found this to be a problem with Cadillac XT5 models from 2017 through 2019 also in a Chevrolet SUV MODEL of the same years an internal memo was sent out but not notified owners

I keep getting Steering assistance is reduced Drive with care” message. I got it scanned a couple of times through mechanic shop, code comes up with a thermostat cooling issue. I have paid 2 shops to run a cooling pressure test and all come up negative. How can a steering issue error lead to a cooling issue. Took it to the dealership, probably wiped the error, stopped for a month before came back. Love the vehicle but this is pissing me off.

In 2021, I took my car into a GM facility to be repaired bc the A/C kept going in and out. Car was under warranty, however, GM mechanic just did a “bandaid” fix and replaced the thermostat, when there was a service bulletin put out in 2017 for this very issue. 3 years later, my car is having the exact same problem, and since car isn’t under warranty, GM will not fix it, even though I have proof they didn’t fix it correctly the first time. The service bulletin is titled, “17128: Service Update - Potential Loss of HVAC Control- (March 30, 2017) This issue started in October 2021 the first time, was temporarily fixed. It started again in October 2024 and is ongoing.

While driving my vehicle, alert popped up on my dash stating "Steering Assist is Reduced Drive with Care" futhermore after that my Check Engine Light Turned on and my Engine Heater Stayed cold and would not warm up. Vehicle has been inspected by the Cadillac Dealer and they stated it is all due to the Sensor. However Sensor is on backorder and has taken them 3 week to get the part. They stated it is safe to drive even though all those alerts came up, since he said it appears to be stuck open, however they stated if it gets stuck in a closed state then the engine could overhead which would require having the vehicle towed in. They offer a "limited" warranty on this however since I just was past the warranty period they state you have to pay the full price. Warranty is for 85,000 miles and I am barely above it at 87675.
