The problem started with the timing chain, which led to coil issues and catalytic converters issues which led to low head beams constantly burning out. Everytime work is done it causes a chain reaction to other parts in the car that requires more and more money. Now the engine light is still on and I am told that since the first catalytic converter was repaired, the second one now needs replacing and the low head beam on the passenger side has wiring issues that will not allow the new bulb to burn, I am told that the wiring appears to be spliced. The catalytic converter was replaced in April and so was the low beam bulb. Headlight was replaced in April, 2015 it is not working today and was told by dealership that the wiring had been spliced or burned out. Radio speakers do not work and all was centered around issues with coils and catalytic coverters.

The fuel pump fuel feed line has developed a leak and is spraying fuel creating a fire hazzard. On top of the tank sits the fuel pump. On the fuel pump the feed tube connects to the fuel line which then goes to the engine. This leak created a fuel odor and got progressively worse. I found dampness on top of the tank, which was gasoline. Upon my further investigation I noticed the fuel spraying out of a pin hole sized crack. This is similar to a recall issued on other GM vehicles in the past and I feel the Cadillac Cts should be included. I've notice other people having the same issues via an online search at Cadillac web forums. I performed the repair myself but it is a very labor intensive and expensive repair for a non capable person if done by a dealer or repair shop. We are talking about a 6 hour job because the rear frame, differential, exhaust etc must be removed to access the gas tank. A major issue and safety risk in my view. The leak will occur whenever the car is on as well as off since the fuel system is under pressure. When car was parked - my garage smelled like gas the leak was so bad. ** I have photos and video and will upload at a later time. ** this car is a perfectly maintained vehicle and still appears brand new - no abuse or other issues caused this defect in the fuel pump module.

Car was towed to dealer. Repairs findings included a melted fuel pump harness and fuel pump inoperative as a result. I feel under certain circumstances the results could have been catastrophic resulting in damage, injury, or possible death.

CTS 6-cyl

  • 70,000 miles
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.

CTS 6-cyl

  • 56,440 miles
I was traveling at 25mph when there was a sudden very loud explosive/grinding noise(it brought people running out of adjacent buildings). I hit my brakes immediately, but the noise continued until I put it into park. I exited the car and under the rear axle of my vehicle were multiple large bolts and screws lined up in a row. The vehicle was totally disabled, and subsequently was towed to the dealer. They determined that all the rear axle bolts just fell out at once.there was no other damage found to the vehicle. My concerns remain as to "why did this happen" and "what if I had been going at an accelerated rate of speed"? multiple experienced mechanics and specialist (including Cadillac) have no answers to these questions and have never seen this happen before.
