First it was adaptive shifting three days after having it, then it was the thermostat, now it-??s needing a new right rear hub assembly but my main concern is the shuttering when I am accelerating. The ride is not smooth. there is a chatter happening when I drive it. It makes me very nervous. I have went to one mechanic to diagnose so far and he said to have the transmission flushed first but it may need the torque converter replaced.

The thermostat is malfunctioning. Vehicle has less than 50,000 miles. 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. If this had been in the summer the A/C would not have worked. I was informed I could bring in the vehicle to have the codes cleared and the parts would have to be ordered. Due to backlog of parts, it was unknown when the parts would be available. In searching internet there are a significant number of owners who have experienced the same issue. In consulting the mechanic, I use, I was informed this is an issue with the motor in my vehicle. The same motor is in other GMC products, and he has 3 vehicles in his shop with the same issue waiting parts.

For about 2 years now we have been receiving a service transmission soon warning from our 2017 Cadillac XT5 but every time we take it in to Cadillac they state that they can't duplicate the warning. I have pictures documenting almost every time the message has come up except for two time including the most recent as I didn't have my phone on me at the time. It has been to Cadillac 3 or 4 times for this. The most recent time we received this message there was a message following that stated your transmission will not be able to shift soon while on the xpressway and we were drive 65 mph with our kids in the car, I was not able to get pictures this time as my husband was driving and I didn't have my phone on me. We have taken it to Cadillac and they say they can't duplicate the message and they received no code warnings. We have been hearing strange sound during gear shifts and the transmission sounds like it is working really hard around the times whenever we received these messages. The car also handles very differently and difficultly during this time. We are highly concerned as this could cause a major accident if the transmission doesn't shift while driving especially while on the highway.

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.

The contact owns a 2017 Cadillac XT5. When the brake pedal was depressed, it traveled to the floorboard and the gear shifter would not move into park. Also, the service engine, service stabilitrak, service transmission, and entire instrument panel warning indicators were illuminated.

New totally electronic transmission felt strange in upshifting and downshifting immediately after purchasing vehicle and was reported to Cadillac in their customer satisfaction survey within a month of purchase. After five months and 1800 miles, the transmission failed completely. Prior to complete failure, the dealer was contacted and ask ed if there were any recall or issues with the new transmission and he indicated there weren't any. The following day, the transmission became eradict on an interstate at 70mph and we were forced to exist and return home on local streets. The car would only move about 10mph with the engine racing until we finally drove the 20 miles to out home. Onstar was activated and diagnosed a serious transmission issue and scheduled towint to the dealer. The car was towed to the dealer on March 26 and as of April 15 the car has not been returned to me.

My 2017 XT5 completely shutdown on my on Saturday, 10/7. I was at a stop light & when I pressed the accelerator, the instrument cluster had a number of lights come on & the vehicle was very hard to accelerate. I had to pull over immediately & then the car shut down. It was completely dead: The hazard lights did not work (very scary) & onstar and the sos button would not connect. After about 5-10 minutes, onstar was connected & I was told not to drive the vehicle due to engine & transmission codes. The vehicle was towed the dealer by roadside. On Monday, the dealer provided me with a loaner while the diagnosed the vehicle. On 10/11, when I went to pick-up the vehicle, I was told the issue was a 'logic lock, ' the car was driven for 4 miles & considered fixed. I refused the car as we need to know the root cause. The dealer still has my car and has not contacted Cadillac yet. I am still waiting to hear from them and also have a case opened with Cadillac customer care, but they are less than helpful. The poor customer service is one issue, but the greater issue is the safety of my car and the fact that it completely died on me and the dealer thinks clearing some codes will resolve it. Please help. God forbid this happens to me or someone else again. It is completely unsafe.

Purchased new XT5 in Feb 2017, currently 8300 miles. After starting my vehicle and shifting into reverse, the transmission makes an loud bang and lurches backward. The first time it occur in May 2017 it caught me off-guard and the vehicle moved backwards about 3 feet. Since then this has occurred about 12 times and have returned the vehicle to the dealer for service, no issues found or repeated. Returned the vehicle again 8/28/17 for service for the same reason. Also the suspension is very rough, wheels fell like they are constantly shaking, large bumps in the road cause the vehicle to loose traction and deviate from lane of travel. Steering makes a loud whining/clicking noise. Steering was service in July and found loose mechanical item. 3 weeks later the same noise has returned. I believe the way the vehicle handles bumps in the road is causing the steering issue. Driving around curves and hitting a bump or depression in the road causes the vehicle to skip across the road surface and momentarily loose traction and steering control. Driving the same XT5 loaner car, does not have these suspension issues. Additionally, the audio randomly stops working, turning the car off/on allows audio to start working again.

While driving 30mph on city street engine made loud roaring noise and dramatically slowed itself down to almost a stop as if I slammed on brakes. I had vehicle(1715 mileage) towed to dealership. They kept it 2 days and told me nothing was wrong. I picked up car and while driving home the engine made loud noise and dramatically slowed down once again. The next day I took my car to another dealership hoping they could repair vehicle. They kept car for 14 days and told me they could not duplicate concern and did not repair. So I picked up car hoping it would not happen again. It did happen 3 more times. One incident happened while driving through intersection on city street engine made loud roaring noise and abruptly slowed itself down to almost a stop. But in this instance when I stepped on accelerator to drive forward to get out of intersection the car would not move, it froze. Luckily I did not get hit in the back. I waited, turned car off, and then turned it on. I was able to drive home. I took car back to dealership on 7/19/17 explaining the car was unsafe since these problems are erratic and I could get hit in the back when the vehicle slows down to a stop in the middle of traffic. They kept car for 9 days called and told me they could not find problem so they wanted their loaner back. I was afraid to drive car back home so the dealer delivered car to my house and took back loaner on 7/28/17. It has been in my garage since then since I fear for my safety and my family and will not drive car fearing I'll get hit while driving if the vehicle malfunctions again. I never get a warning of any sort before it happens. After it happens and I turn the car off and on again the vehicle seems perfect. But I never know when it will break again since it is erratic. It is definitely a safety hazard.

Randomly, after starting the vehicle and moving the shift lever to reverse, the emergency brake independently sets such that park is displayed on the dash as well as reverse. In other words, the vehicle is in both reverse and park simultaneously as displayed on the dash display. However, I am told by GM that the park displayed on the dash is really indicating the emergency brake is set and that the transmission is not in park. If the vehicle can independtly set the emergency brake when moving the transmission out of park, can this happen when the vehicle is in motion? if so, a disastrous accident could occur.
