2017 CADILLAC XT5 Electrical System Problems

There is an open service bulletin on my car - 17128 Potential Loss of HVAC Control. This loss of control affects the defrost on the vehicle making it very dangerous to drive when it is raining out as it severally reduces visibility.

Steering reduced assist drive with care on the dash board . It states drive with caution not sure if this is dangerous or even driveable I am 8 months pregnant and now I don’t have a car I am scared to drive it. Thermostat stopped working & fan is running and won’t stop

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.

The tire air pressure gage on the dash is steadily illuminated but there is nothing wrong w the air in the tire.

At approximately [XXX] on [XXX] ,2024 I was at the intersection of [XXX] when my vehicle stopped running completely. All lights on the dash went out and the doors were locked which prevented me from exiting the vehicle. No systems would operate at all. All I could do was sit there. Fortunately, I had a cell phone with me. I called my local Cadillac Dealer for advice, they had very little. finally a lady there told me she would call a tow company they recommended, which she did and the tow company, Shawnee Auto Body did respond about 20-30 minutes later. In the meantime, a gentleman from a local tree company arrived on the scene and helped me, by placing an orange traffic cone behind the vehicle to keep oncoming vehicles from rearending me. after a few minutes the doors did finally allow me to exit the vehicle, which I...

When you put the car in park, reverse, drive it jumps forward or back.

While driving the vehicle started to accelerate in its own. There was nothing obstructing the pedal. I could press down on brake with some resistance, but as soon as brake was released the, the vehicle accelerated. The vehicle did not level out with speed but continued to accelerate over 80 mph. This lasted about 8/9 mins, being controlled by riding on the break. It did it again for about 2/3 mins about 15 mins after first occurance. I took the car straight to get it looked at and the mechanic said that they could not find anything wrong with car

Since 6/2022 and again 7/2022, 10/25/22 1/31/23 Constantly stating service error codes for stabiltrak, antilock brakes, and brake assist not functioning and need service urgently. However when I take it to the dealership they find nothing wrong and further investigated at another Cadillac dealership they also state they found nothing. These errors continue to pop up intermittently and my Cadillac app reports them as needing service.

The contact owns a 2017 Cadillac XT5. The contact stated while driving 60-65 MPH with her granddaughter seated in the rear seat, the vehicle shut off inadvertently in the middle of the road. The message battery low was displayed. The vehicle failed to restart after several attempts. The vehicle was towed from the middle of the road to the side of the road. The vehicle was then towed to an independent mechanic and was diagnosed that the electrical system had failed. An unknown repair was completed. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 72,000.

XT5 bumper-to-bumper warranty expired on 6-1-21. Both key fobs suddenly quit working on 7-17-21. Took to dealer 7-21-21. Cost me $300. Got it back on 7-26-21. Drove vehicle for the first time after getting it back on 7-28-21. Key fob quit working again briefly then started after I kept trying for a few minutes. After driving for 5 miles, the car completely died on very busy road - no steering, no dash lights, break lights - then the car suddenly braked really hard and i almost got rear-ended. 4-way flashers wouldn't work so I had no way to warn other drivers coming up behind me. I also was a sitting duck as I couldn't exit the vehicle since the doors wouldn't unlock and windows wouldn't go down. The temperature was in the 80s and I quickly began to overheat. I tried to signal other drivers who were beeping their horns...

SITTING AT A STOP LIGHT AND CAR LOST ALL POWER. NO ABILITY TO TURN ON HAZARD LIGHTS OR CALL FOR HELP OR ANYTHING. IN MY OPINION THIS IS A HUGE SAFETY ISSUE SINCE MY WIFE COULD HAVE BEEN REAR ENDED SINCE THERE WERE NO LIGHTS AT ALL ON THE CAR AND NO WAY TO TURN ON ANY WARNING LIGHTS. THANK GOODNESS THIS HAPPENED WHEN STOPPED AND NOT MOVING. I COULD NOT IMAGINE THE OUTCOME OF LOSING POWER AT SPEED WHEN EVERYTHING IS ELECTRONICALLY CONTROLLED.

THE "CUE" SYSTEM HAS MALFUNCTIONED. I HAVE NO NAVIGATION OR RADIO AND AM UNABLE TO SEE HOW THE CONTROLS ARE SET FOR CLIMATE CONTROL. ALSO, THE 360 DEGREE CAMERAS FAIL INTERMITTENTLY INCLUDING THE BACKUP CAMERA LEAVING ME BLIND WHEN PARKING OR BACKING UP. I HAVE TAKEN THIS VEHICLE TO THE DEALERSHIP FIVE TIMES AND CADILLAC HAS NOW DECLARED MY VEHICLE A "LEMON" AND IS REPURCHASING IT. INTERESTINGLY, I'VE BEEN DRIVING TO CADILLAC DEALERSHIPS THROUGHOUT CENTRAL FLORIDA AND HAVE NOTICED A HIGH NUMBER OF XT5'S WITH THEIR DASHBOARDS COMPLETELY DISASSEMBLED IN THEIR SERVICE AREA. ONE SERVICE TECH ADMITTED HE'S ALSO SEEN THIS ISSUE IN OTHER XT5'S. THIS SOUNDS LIKE IT COULD BE A PATTERN AND CADILLAC IS DENYING TO ME THAT THERE IS A PROBLEM.
