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.

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 has shown the service stabilitrak, tcs off, and transmission unable to shift soon while driving. This happens several times; and after certain times the car will not shift and I am not able to go past 50-60 mph.

As I was driving I smelled a burning smell. A few seconds later saw a fire/smoke coming from the front right side of my car. I pulled over and took a look. Confirmed my car was on fire. I called 911 who connected me to the fire department. I then ran to the gas station and got a fire extinguisher. I then used the fire extinguisher and extinguished the fire. I made a claim with my insurance company who ordered a tow truck to Transport the vehicle to an auto repair shop.
