2017 Cadillac XT5 Problems

I bought this vehicle with 74k miles the car when cold starts well but when you start to drive and at 24 miles an hour it kicks then shutting till 30 mph then once warm the kick goes away but you feel a little kick when down shifting I contact GM about it was told no recall the previous owner said he took it when it had about 50k miles and they said the same thing so I took the vehicle to ammaco transmission shop they serviced it and the car still had the issue they told me it could be an issue with software.. I called once more to Cadillac and was told no recalls.. so I just feel like I have to give up and just drive it till it stops… I spoke to a retired mechanic and was told to leave you a message about the car.. he told me dealers will tell me to pay for a software or replace it I called and asked to see if they can please check the software and was told I have to pay $250 an hour and it might take 2 hours to check. I was told about a good will check.. I just don’t have the funds to replace this transmission and wanted to see if there is anything that you possibly can help me with

I purchased the car on XXX. The car has been returned to the service department within the first 3 days. Sold to me without getting fully inspected. Service department did put new brakes and rotors on and I was told (no paperwork given to me) an oil change was done. On XXX in traffic on a dangerous highway, the car cut off. The car was not able to be jumped with AAA, was towed to [XXX]/GMC Service department. I was told by the Asst Svc Manager, on XXX the Tech told him My car was the starter. The part would have to be ordered and would not be ready to the following week. On July 7th I received a call from the SVC Mgr that the engine blew. I had to pull teeth to get the Mgr to pay for the engine of $8500 and yet he wants me to pay $1500.00. With having a car less than 21 days regardless if I went over the 3k miles and as -is, there was a 90 day warranty when everything should be covered. He has now rescinded because I reported this to BBB, Atty Gen office, NHTSA. This car was never inspected. I requested the On-star reports, Inspection reports for the last year and the Tech's findings and nothing has been provided except one. I requested several times the service report and the General Manager/owner is so upset, he submitted nothing.I have felt intimidation throughout this entire process. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The thermostat quit working. I've researched this issue and have seen this is a very common issue usually occurring when the vehicle has somewhere between 45000 to 55000 miles.

I had P0128 Code with a warning message " Steering assist is reduced, drive with care". My local mechanic told I need a new thermostat. I have replaced my thermostat and it cost me 700 dollars out of pocket.

I purchased this used car in the end of July 2025. Within the last month the service transmission light came on. Within a 24-hour period, the message changed to, "service transmission unable to shift Soon". Also alarm bells go off when I first start the car and sometimes during driving. The car feels like it drives correctly and smoothly with no shifting issues. Sometimes when that second message and check engine light icon being comes on, there seems to be a third message that is trying to pop up behind it but it does not. It seems like there is a glitch in the system. This was very concerning and scary for me. My research shows me that this has been a chronic problem for my make and model and year of car. I've also heard it can be even time to check and or change the transmission fluid. That needs to be a different message all together without causing alarm that the transmission itself is not functioning properly. I have not driven this for 10 days because many repair shops in dealerships are telling me not to risk it and of course want me to bring this in for a diagnosis. It is costly and hard to discern and trust who to go to for the correct information. The dealership should be responsible for a recall and replacing this sensor or modular so people do not have a cause for alarm if it is something as simple as needing to change the transmission fluid. There is also no dipstick on this vehicle so no local fluid fill station can check this. Many people have complained and are at a loss. I see there is a bulletin on this subject but no recall. Please take action and turn this situation into a recall once and for all to help. The little folks like me stay more safe and better informed about the health and longevity of our vehicles. Thank you for your time in reading this.

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.

The thermostat has malfunctioned twice in 2 years. Driving vehicle and dash warning" STEERING ASSIST IS REDUCED DRIVE WITH CARE", also the temperature gauge was showing COLD and this was after driving for over 30 minutes. Contacted local dealer and was informed this is a KNOWN problem with the thermostat sticking open. My brakes are sticking often and my car often jumps hard when i put it in reverse.

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 straps on the seat loosen on their own when pulled, without pressing on the button to loosen them. This would be dangerous in the event of an accident because the straps could loosen and the child would not be secure. The car seat has always been installed in the car seat base (from the manufacturer). The car seat is available for inspection if needed. The car seat has not been inspected by a third party. I reached out to the company, Nuna, to let them know if the issue and they refused to inspect or replace the seat and the only solution they suggested was that I purchase a new seat.

The straps of the car seat loosen on their own, without holding down the button to loosen the harness. It’s unsafe to continue to use this seat as the straps will not stay tightened in the event of a car accident. The seat is available for inspection if needed. No the seat has not been inspected by any third party.

While driving down the freeway at approx. 65 miles per hour, I heard a very loud sound like an explosion, or a huge balloon exploding, and then heard crackling of glass. It was very scary and dangerous. I had to slow down immediately, and was able to get off the freeway. I pulled into a gas station, and tried to figure out where it came from. I realized that my sunroof was either hit with something or just simply exploded. There was a hole in the center, and the glass was cracked throughout the front sunroof. I could hear the glass pieces moving around on the sunroof shade that was thankfully closed. I bought duct tape and covered the hole and all of the cracks so I could drive it home. I took side streets and drove slowly home.

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.

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 contact owns a 2017 Cadillac XT5. The contact stated that while driving at an undisclosed speed, there was an abnormal clicking sound coming from underneath the vehicle while accelerating or decelerating. There were no warning lights illuminated. While having the tires replaced, the contact was informed that the rear toe links were loose. The vehicle was taken to the local dealer two years prior for a toe link replacement, but the failure occurred. The manufacturer was not contacted. The failure mileage was approximately 15,000.

My passenger side, dashboard bowls up in the heat and doesn’t seat properly. My fear for safety is that if I’m in an accident that airbag will not come out due to the dash bubbling because of the defect.. It seems to be an only problem with the platinum editions of the Cadillac XT5’s. There’s no warning lamps and it has not been inspected.

9/17/25 I purchased 2017 Cadillac Xt5 platinum from a dealership. It came with a dash mat which was concealing cosmetic damage to vinyl around air bag on passenger side, and was unglued throughout entire dashboard. I didn't have a vehicle inspection before buying car, nothing reported on Carfax. And I asked dealership why they used Velcro and dashmat to conceal damage. No response.

TL* THE CONTACT OWNS A 2017 CADILLAC XT5. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS OVER BUMPS IN THE ROADWAY, THERE WAS AN ABNORMAL SQUEAKING SOUND DETECTED FROM THE FRONT END. THERE WAS AN ABNORMAL SQUEAKING AND GROWLING NOISE DETECTED FROM THE DRIVER'S AND PASSENGER'S SEATS. THE DRIVER'S SEAT APPEARED TO HAVE A HOLE. THE TRACTION CONTROL WARNING LIGHT WAS ILLUMINATED. ADDITIONALLY, THERE WAS A VIBRATION IN THE ACCELERATOR PEDAL. THE VEHICLE WAS TAKEN SEVERAL TIMES TO INTEGRITY CADILLAC (6025 INTERNATIONAL DR, CHATTANOOGA, TN 37421, (423) 954-7632) AND DIAGNOSED THAT THE PASSENGER'S SEAT AND STRUTS NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED HOWEVER, THE FAILURE PERSISTED. THE MANUFACTURER WAS CONTACTED AND STATED THAT THE VEHICLE WAS NOT COVERED UNDER WARRANTY. THE FAILURE MILEAGE WAS 5,500.

WHEN TAKING TURNS, EITHER LEFT FOR RIGHT, THE DRIVER SEAT MAKES CLICKING NOISES AND THERE IS A FEEL OF THE SEAT SHIFTING TO THE SIDE. THIS IS VERY PREVALENT WHEN GOING THRU ROUND ABOUTS. AT TIMES WHEN THE VEHICLE IS PARKED AND DRIVER REACHING TO CLOSE DRIVER DOOR THE SAME PROBLEM IS APPARENT.

The problem I am having with my car is a safety issue and their is not a safety recall on my model 2017 but their is one on model 2018 with same issue as mine, the issue I have is every time I fill my gas tank full or halft tank and when I live the gas station hit the road when I stop at a red light or stop sigh the car start shaking and turn off, I have to put the car on park and turn back on and start driving, car shakes while driving and at next red light it turns off again i wait until lights turns green and turn it back on. I replace many parts and nothing seeings to work I believe this comes from manufacturing issues. I am the second owner and I bought it with 21k miles used. But 2018 model have this issue and is on recall but dealer won’t do nothing because don’t have a recall.

STABILIZE WARNING KEEPS COMING ON AND SAYS TO SET PARKING BREAK AS WELL. READING ABOUT THIS, IT IS A VERY COMMON WARNING THAT CAUSES THE STABILITY SENSORS TO FAIL AND INCREASE LIKELIHOOD OF A CRASH FOR SOMETHING THAT IS SUPPOSED TO BE A SAFTEY FEATURE ON THIS VEHICLE. THIS CREATES AN UNNECESSARY SAFTEY HAZARD THAT CADILLAC WILL NOT ADMIT TO OR FIX. THIS SEEMS TO ONLY HAPPEN WHEN SITTING STILL AT A STOP LIGHT OR STOP SIGN.

Body Issue- Left and Right Front Doors of Vehicle air popping and Grinding when opened. No Damage or Accidents have occurred to the Vehicle for this Function to have a Error.

TL* THE CONTACT OWNS A 2017 CADILLAC XT5. WHEN DRIVING IN THE SUN AT ANY SPEED, THE WINDSHIELD ACTED LIKE A MIRROR AND CAUSED EVERYTHING ON THE DASHBOARD TO REFLECT ONTO THE WINDSHIELD. THE DRIVER'S VISION WAS OBSCURED. THE VEHICLE WAS TAKEN TO A LOCAL DEALER WHERE IT WAS DIAGNOSED THAT THE FAILURE WAS A SAFETY ISSUE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND STATED THAT NOTHING COULD BE DONE. THE FAILURE MILEAGE WAS 250. ..UPDATED 11/21/16 *BF UPDATED 12/13/16.*JB

2017 cadillac XT5 Platinum. Seatbelt CHIME does not activate if the seatbelt is off while driving. Dealer says it is working as it is supposed to in this model year.!!!! Please note that at the dealer we test drove for 3/4 of a mile, and the CHIME went off only after driving 4 blocks and making a right hand turn. It went off again seconds later and 1/2 mile later as we entered the parking lot, as we hit a bump into the parking lot, the chime went off again. My point is that the CHIME should go off at the beginning of the drive to remind the driver that the belt is off, not at the end of a 3/4 mile drive. Their answer is that they tested the seatbelt and no codes were detected. Since the CHIME did go off sometime during the drive, then there is no problem!!!! They CLAIM they tested another 2017 XT5 and it was the same!!! It worked for 8 years, but in the last 2 months, it started to fail with on the driver side. The passenger side later also started to fail, sometimes it will activate if no seatbelt was used, other times it did not. Today June 11, 2026 I tested the car and no chime was active. I also tested the rear seat and buckled & unbuckled while driving - NO CHIME. I tried bouncing up and down on rear seat, and the CHIME went off! So the CHIME works but the car is not sensing when the seatbelt is unbuckled. I have grand children that ride in the rear using a car seat, if one of the seatbelts was unbuckled while driving, the CHIME would warm me that they took the belt off. We drove the car for 5 miles home and bucked and unbuckled the and passenger and the driver side belts at different times, and the CHIME did not go off. The light in the front panel does flash when the seatbelt is unbuckled!. Prior to the belt CHIME giving us problems, the same week the seatbelt on driver side tighten so hard while driving, that my wife got scared & even was afraid it would break her clavicle! We could not reproduce, but reported to dealer.

i was involved in a front end collision with a car that pulled out in front of me without looking. I ended up T-boning the car at approx. 20-25 MPH. Both myself and my wife were wearing our seat belts. Mine held but the passenger one held only the lap belt part. The shoulder part of the SB allowed her face to go crashing into the dashboard. She ended up with abdominal injuries and head trauma. I took it to the dealer and they say the seat belt will need to be replaced as it is defective. (You think). I can pull on the shoulder strap rapidly and it will not 'catch'.
