Driving at highway speeds, engine started to hesitate and run roughly and got increasingly worse. When pulled over, noticed that gas gauge was going down. Immediately shut off vehicle and stepped out. A massive puddle of gasoline had formed around vehicle, and gas was dripping from the entire bottom of the car, and had even gotten into the door jams and was running onto the ground.

On may 18th, 2018 I purchased a 2004 cadillac cts from top notch auto. The gas gauge, brakes, A/C, blinkers dash buttons all were not working. He said to bring it the next day and they would fix it all. I ran out of gas getting there the next day due to not having a working gas gauge. I spent the entire day there and they did nothing to fix the car. The next day the computer (ECM) went out on the car and the engine light came on saying the catalytic converter was bad. I took the car back and asked for my money back and they said no but would fix it and they had the car for over two weeks. They said everything was fixed but I noticed the car went from 176000 miles to 101000 miles (odometer rolled back). I asked about this and he said it was legal and necessary to fix the car. The day after getting it back the service engine light came on again and the car would not go over 20mph on the road. The codes read po121, po23 and this time it was the throttle body and wiring that were bad. The dealer would not pay for it. I paid $498 out of pocket and another 3 days without the car. I told him the brakes were still bad and the car barely stops and pulls hard to the right. On friday june 22nd they told me to come in to get the cars VIN checked out for my registration and so they can look at the brakes. They said they brakes are fine (they are not) and he took my keys and would not return them until I signed documentation saying I would not complain or take him to court. It is now july 9th, 2018 and they will not give me my plates or registration and say I am stuck paying for this death trap of a car.

This vehicle has had thousands of complaints about ECM related problems. Every complaint is the same. The computer causes the temp gauge, fuel gauge to stop working, the tc light & antitheft lights to come on, and the key being stuck in the ignition. It renders the car undriveable because the temp & fuel gauges stop working. I have researched this and there has been the exact same issue with thousands of cars!!! When I contacted cadillac about this they said I would have to pay hundreds of dollars for a diagnoses fee. I told them that this is obviously a defect with poor design and/or bad parts. I have included just one of many links that owners have had with this model of car. This model needs to be recalled and cadillac needs to fix this ongoing problem!! Http://www.topix.com/forum/autos/cadillac-cts/t0o6tkb3dqgank509/p3 this is so wrong that they have received thousands of complaints for the exact same problem I mentioned above and have done nothing to fix it!!!!

Service theft system has came on randomly which would not let the car be moved out of park. Which also causes the key to not be removed from ignition. The car also has intermittent starts and can be jumped at the starter relay in the fuse panel. This all happened when the car was stationary. It makes the gas gauge and temperature gauge not work but speed and RPM do work.t he lights on the shitter do not work along with rc not functioning and theft symbol showing on instrument cluster also..

First incident: when driving, engine would loose power, engine light on, fuel pump replaced second incident: two weeks later, driving car and engine shuts down, no power, no brakes, no power steering, gas mileage to empty was at 68 miles. Replaced fuel gauges third incident: one week after replaced fuel gauge, engine shut down while driving, no brakes, no power steering, and gas mileage read out was 69 miles. Fortunately, we were at a standstill in the middle of the road and the car restarted, went to gas station, filled the car with gas, it took 14.7 gallons, the cts gas capacity is 18 gallons. Dealer doesn't know what the problem is. Just waiting for a solution. This is a major safety concern that needs immediate attention.
