2019 Cadillac XT5

I keep getting a warning to service the Safety Restraint System. I have taken my car in several times to be fixed and have paid a lot of money and it is still not fixed. The dealership says they fixed it but then it happens again. This has been going on for about 3-4 months now. At this point I do not know what else to do. I feel this is a safety concern because I cannot drive down the road without the alerts going off in the car.

Was driving the other day and the message steering assist reduced, AC fan was blowing but no A/C then engine light came on. Made appointment next day with my Cadillac local dealer and service writer said he knew what the problem was. After he plugged into my car, then into his computer it read - bad thermostat. Fortunately, mine was covered under the powertrain warranty, however, he said there were 4 other vehicles just like mine (XT5) in there for the same issue. This is a well known issue with Cadillac and for those of us who have a warranty that's good. Otherwise, it is $1,200 to fix!!! Ouch!! Not sure why Cadillac hasn't issued a recall on this problem and very disappointed in them for not doing so.

Message Displayed on 2019 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 2017 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.

While traveling home to Louisiana from a vacation, I noticed the engine temperature what stuck on Cold. We also were experiencing loss of power steering, and loss of AC in the car. We stopped at AutoZone in Destin, FL where they completed their FixFinder which reported the thermostat needed to be replaced, being it was stuck in the open position and wasn't properly gauging the engine temperature. Some of the engine fluids were extremely low due to overcompensation because of the thermometer issue. Seeing as we were traveling and not near our local mechanic or dealership, we called around to various auto shops to see who could fit us in same day. The only available shop, without having to spend an additional night in FL, was Pep Boys in Fort Walton, FL. They also let us know they did not have the thermostat compatible with my engine in stock, so that would need to be purchased at AutoZone if we wanted the car fixed same day; which is what I did. While we were at Pep Boys, there was another Cadillac xt5 there for repairs to their AC. It turned out, they were having the exact same issue I was having, but it hadn't escalated to the power steering yet. The mechanic googled the two issues and found there are known issues with the engine thermostat in this make/model, but there has never been a recall issued for it. Now Cadillac is refusing to reimburse me for the repairs because I was still within my Powertrain warranty (under 73k miles) but because we were in a hurry to get home from vacation to get back to work, we did not take the car to a GMC dealership, so the Powertrain warranty is apparently useless here. My extended warranty is also useless because the Powertrain warranty is still in effect.

My vehicle is receiving a notice "Steer Assist is Reduced Drive with Care". Per discussion with the dealership this is a result of a thermostat issue causing an issue with the grease temperature in the steering. Based on a bulletin to the dealerships from 2017 this is a known issue and continues to be a known issue for multiple GM vehicles. GM can not supply new thermostats to dealerships and they are just resetting the warning. Steering is a critical issue and GM is aware of an issue and is not recalling or repairing timely.

Per the owners manual, the vehicle is supposed to be equipped with four reinforced jacking points for the vehicle supplied jack. The two front reinforced points were never installed. Besides, there being no way to jack up the vehicle, it some one unknowingly attempt to jack up the car, it could fall off the jack and injure or kill someone. I went to the dealer, and upon inspection they agreed that the points were missing. I contacted GM, but after one call, no one responded back to me.

Service stability track light came on. Brought to Mechanic hooked up to computer. No code shown. Mechanic says car is fine. Keep it off for 15 minutes and the computer will reset. Driving on the highway Emergency brake came on by itself and stopped the vehicle all caution lights lit up on on the dashboard. Service engine light came on brought it back to the mechanic again no codes shown drove it for three days has been running fine and on the fourth day vehicle will not start.
