“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”

“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 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 He has now rescinded because I reported this to BBB, Atty Gen office, NHTSA.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…”

“FORMAL VEHICLE SAFETY COMPLAINT 2017 Cadillac XT5 – Electronic Brake Control Module Failure and Unavailability of Replacement Parts Vehicle: 2017 Cadillac XT5 – Mileage: Approximately 70,000 miles Manufacturer: General Motors / Cadillac I am requesting that the National Highway Traffic Safety Administration review a potentially serious vehicle safety issue involving the electronic braking system of the 2017 Cadillac XT5. The vehicle has displayed the following dashboard warnings: •Service Brake System •Service StabiliTrak A General Motors authorized Cadillac dealership has diagnosed the problem as a failure of the brake control module. Of particular concern, the GM dealership informed me that it has been unable to locate a replacement part, even after conducting a nationwide search of GM parts as well as after-market parts sources. This seems very unacceptable. This situation raises two significant concerns: 1.A malfunction involving an essential electronic braking and vehicle stability-control component may compromise vehicle safety. 2.An owner of a relatively low-mileage vehicle (approximately 70,000 miles) may be unable to obtain a necessary safety-related…”

Vehicle speed control

9 reports2 crashes
“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”
