Driving on highway approximately 70mph. Vehicle suddenly bucked twice, a few seconds later a check engine light appeared and reduced power appeared in the message center. The vehicle started to slow its speed. I had three miles until next off ramp. Vehicle continued to slow as I got it off he highway. Once off the highway I pulled over and the vehicle stalled. I noticed fuel gauge was reading empty, before problem was approx. 1/4 tank. Vehicle know had a heavy fuel smell. I had vehicle towed home. The following day I investigated the problem. ( I am a professional mechanic with over 30 years of experience. ) the fuel gauge read empty and vehicle would not start. I added approx. 1 gallon of fuel and tried to start the vehicle. Gasoline immediately poured from a fuel line at the rear of the engine. I removed the engine cover and noticed the high pressure fuel pump was loose from the engine. I checked the supply fuel line and it was very loose or broken. Realizing damage was comprehensive and should be covered under warranty I towed car to dealership for repair. The dealership was very uncooperative and charged me for the replacement of a broken fuel line. I asked the dealership to investigate why the pump came loose from the cylinder head. They said it just happens and it was retorqued to factory specs. That vehicle was not test driven after repairs were made, I was told it was but it had no gas registering on the gauge and the mileage had not changed from time of drop off. I picked up vehicle from dealership, put a half a tank of fuel in vehicle at the closest fuel station and drove it home cautiously. I will not be driving vehicle again until I get more answers. I believe a serious fire is possible if the fuel line breaks again very lucky it did not happen the first time because of the fuel pump coming loose from the engine.

I turned a corner, drove through some sand on the road and broke traction. After that, the traction control system lights came on and within several seconds the check engine light came on. I had onstar service run remote diagnostics and they found ABS failing and a cylinder misfire. The car took an immediate loss in power and started to shake at all power levels.

The "check engine" indicator came on, soon thereafter, "stabilitrak" and "engine power is reduced" indicators came on. Ten minutes later, the car shut down in the middle of the highway. After 10-15 minutes, the car started up again with the "check engine" light still on. Car was repaired at a cadillac dealership. Service representative advised that it was necessary to solder some wires/terminals behind the right rear wheel well fender liner. A service bulletin (pie0291b) identified this problem. This same exact problem arose in mid-february. The remedy at that time was to replace the throttle body. Hopefully, this new remedy will work now that there is a service bulletin to assist with the diagnosis.

I bought this car new on 1/16/14. On 2/19/14 the engine light came on and the engine lost power. I took it to the dealer and they replaced a sensor assembly. On 3/18/14 the same thing happened and the car lost power. The mileage was about 1,500.. Now I am being told that there is a problem that the engineers at gm are looking into but no fix is in sight.. The first two times I lost power I was in town but if this happened on the highway it could be a real problem. I feel gm has a major problem and they do not want to be honest. I am being told nothing other then they are working on the problem.
