Transmission cooler line fittings have dissimilar metals causing the threads inside the radiator transcooler to strip and dump coolant into Transmission lines and on road along with what was the transmission fluid as well as steam rolling out blocking vision through my windshield going uphill on a dangerously busy road crossing.This is a well known manufacturing defect that has yet to be handled. This could have gotten me and my 3 year old son seriously hurt by sudden loss of power and slick roadways not being able to avoid or brake properly or even steer away from on coming collision. The dissimilar metals are aluminum nut with a mild steel washer backed by a stainless steel washer before it contacts the radiator. This car has 101k miles and has been babied it's entire life. And when I see the 4 brake lines are about to rust out after all the repairs that have already been done. This is just poor quality material and craftsmanship. Easily could have been avoided by simply using a different metal than mild steel between dissimilar metals.

First ECM module needing to be replaced, we replaced it then after that started running rough, took it to auto zone, 12 codes popped up. Did normal maintenance of vehicle, oil change spark plugs . Then a few days later we were on the highway and all of a sudden we lost all power, pushed on accelerator no power, front end started shaking, so pulled over, vehicle was very hot and smells like gas, had it towed compression test were no good, was told gasket were bad, also was told to check the recall list. Im up set because our children were in the vehicle with us. I hope we are able to get whatever needs to be fixed on this vehicle. Thank you.

I went to cadillac to get the recall fixed they said it was closed out and couldn't fix it and now I can't smog my car and I can't tell if I have gas or not and I'm scared to drive it without getting the fuel pump fixed

I just purchased this car in february 2019 and it went down in late april or early may of this year. The service engine light would come on for a few days then it would go off for a few days. The engine would rattle when first cranked and then it got to the point where it would constantly keep trying to crank but never would and now it is completely out. I had it towed to mechanic and was told that they had to put 5 quarts of oil in it but I had the oil changed a month before the car died. They say the oil is going somewhere but where? I was also told the timing chain had failed. When this happens it can cause the pistons and everything else to fail with the engine. It will cost me over $2000 to get repaired. This is ridiculous! Something needs to be done about this. Cadilliac makes everything so expensive so I would not recommend getting one unless you can absolutely afford it and not be in debt behind it. I was in love with this car but this is horrible. This is my second time trying to get it repaired and now I'm done.

There's a very hard jerking coming from some where in the rear area while driving. When this happens there is a lost of power. Also the engine oil is going some where ,I keep having to put oil in it , about two to three quarts a week. When the oil gets real low the engine shakes and runs like crap and acts like it wants to cut off.

Timing chain jumped time. Mechanics working on it state they have read numerous complaints on this but state no recall will be published unless someone gets killed.

Brake system failure: I was driving on the highway and had to execute an emergency stop going approximately 30 MPH on a cool dry road. When I did, the car power, engine, electrical system shut down and refused to brake any more than it did prior to my slamming on the brakes. My momentum would have carried me into the car positioned only a few feet in front of me if I hadn't the presence of mind to instinctively pull off onto the shoulder as to avoid rear-ending the car in front of me. I had to put the car into park in order to be restart it. Immediately I noticed that the brakes felt substantially different. The system lost enough pedal pressure that stopping after that incident required me to drive at low speeds and give myself more distance; thankfully, I still had some ability to stop, at that time. I inspected the brake lines and hoses after parking the vehicle that the steel brake lines had fluid dripping from them. I also noticed that the driver front wheel well liner had a spray of brake fluid that covered the interior portion of the liner, proximally, behind the rim and tire sidewall. I had tested the brakes after that and have no braking ability. I have not touched it since that incident. The rest is ongoing and is separate from the incident reported above. Air bags: the system keeps telling me that the airbag system needs to be serviced. I've read the recall info regarding other cadillac cars and mine meets the same criteria but has no recall notice. Something about this coincidence doesn't make sense... Engine: internal timing chain tensioner has failed and I hear a noticeable ticking of the chain slapping against the sidewall that is emanating from the passenger side of the engine. I have seen, read, heard of other individual owner testimonials that talk about this being an issue that cadillac refuses to acknowledge.
