The engine light on my cadillac cts went on and I only have 62,000 miles . What could it be. this car has been lemon. I already had to replace the suspension and the right and left rods and the refrigeration canister , water pump.
Getting the codes read for the fault is step one. A local auto parts store may do it for free. Post back the code, knowledgeable people will probably chime in.
It could be dozens of things all together or just one. Until you have the codes read, it is just a guess.
