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.

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.

Engine shuts off at stop light restart, stops and restarts or in garage does same thing. We submitted concern to dealer states it is factory setting. This is a safety concern, serious.

My 2017 XT5 has a joy stick issue that at times has trouble going into gear. Service transmission warning comes on then unable to shift soon and then check engine light. Cadillac replace the modular for the shifter in August 2024 now months later mid November they say the shifter has to be replaced approximately November 4 to November 18. The service Transmission warning comes on. And then unable to shift soon and check the engine light comes on. Short drives the check engine light goes off itself, unable to shift and check engine light was 1175.00 $ for the modular August 13 and now they say the shift has replaced cost of, approximately $700. So now they’re doing double labor to replace the shifter. My replacing the shifter it will send signals not to have the check engine light come on.

Defective upper dashboard has large ballooned area in center where adhesive either failed or wasn't applied and lower dashboard has defective lump under material. These defects should never have left the factory. Poor quality control. Both dashboards are to be replaced by dealer.

Message Displayed on 2017 Cadillac XT-5 "Steering Assist is Reduced - Drive With Care". No check engine light, and no apparent loss of steering. Noted that Temperature Gauge and Air Conditioning ceased to work. Suspiciously, a 2019 Cadillac XT-5 that I also own, the identical displayed message came on, with identical same mechanical issue, and just learned that an acquaintance with a newer Chevy Blazer just experienced the identical issue also. All vehicles are equipped with OnStar. Coincidence, OR any possibility that GM or OnStar computers have been hacked into, as OnStar has ability to control various functions of vehicles. To correct the issue (possibly only temporary) was to remove the negative battery cable for a short time, and reattach.

Message Powersteering Assist is reduced. This could cause steering problems and a potential collision. Cause is due to failure of thermostat design and insta llation. Believe an investigation is possibly warranted. GM issued a service bulletin making dealers aware of the faulty design in May 2017. But consumers were not advised of the danger.

I was driving in traffic, about 45mph, when the parking brake came on, I got a check engine light, service brake assist, service stabilitrack and one other light on. I managed to keep it running enough to not get rear-ended, but it is not safe. The dealer now has it, and I am in a loaner. The car has less than 2000 miles on it, and this is the second check engine light (the first did not involve the parking brake), but the dealer did not find a concrete problem for the light. Is this going to turn into a recurring problem? It is very definitely not safe.

Multiple issues with garage remote control buttons not functioning. Issue with driver seat not vibrating when vehicle ventures out of lane with "lane assist" feature on. Vehicle shut down while driving on highway sending multiple warnings about engine malfunction, parking brake on, etc.

Tl* the contact owns a 2017 Cadillac xt5. While the contact's wife was driving at a low rate of speed, the vehicle shut off without warning. After restarting the vehicle, it shut off yet again.

Excessive tire wear. Starting at 17,500 miles all four tires were worn to 4/32". Now at 20,000 miles tires are worn to 3/32 and 4/32. Tires are worn evenly and have been rotated at dealer with service records to support. Dealer told me that the xt5 tires are only lasting 25,000 miles max. I was the third complaint of the day at 1:00 the last time I spoke to the dealer. Tire manufacturer warranties (prorates) the tire for 60k miles but Cadillac customer care says tires are normal wear and will not support the issue, even with only 20k miles.. Clearly with the number of complaints and evenly worn tires , either there is a tire manufacturer issue or gm engineering specified the wrong tire. A Cadillac with 20k miles should not be a candidate for new tires, and gm engineering needs to evaluate

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.

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.

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

Brakes failed. Coming to a stop sign on cr 13, brake pedal went to the floor. Brakes did not slow or stop the car at all. Pumped the brakes 3 or 4 times, no braking. Went thru stop sign hitting another vehicle. Air bags did not deploy. Automatic braking system did not activate. Estimates I was 50 yards from the stop sign when I first applied the brakes, speed between 20-30 MPH.
