Timing chain issues, Sun roof drain clogs, then leaks inside and soaks into the floor carpet. Head lights fog up. Low oil warning non existent. You don't have to change your oil because you have to keep adding a quart every 1000 miles. If this is the best car GM can make they're in trouble.
We bought a new CTS in 2009 fully loaded with AWD. The car was beautiful inside and out and rather pricey also. From the beginning there was issues with water in the trunk lid after it rained or when the car was washed and also an electrical issue when the right blinker was on, the left turn signal would come on and vice a versa, the Cadillac dealer was able take care of. The car had regular oil changes with full synthetic and general maintenance when needed. It was a great car until 73k miles when there was some “missing” in the engine when going up hills at about 52 mph. The car went into a Cadillac dealer and what was thought to be a plugged fuel injector. After 4 returned visits the dealer decides a piston needed to be replaced! WHAT! It was over $2,000.00 for that visit for major engine issue to a vehicle with relatively low miles. Fast forward to 78k miles without any issues, no warning, leakages or dash lights while driving highway speed there is a sudden screeching scream and thumping coming from the car. I immediately pulled over to the shoulder and put it in park which would not stop the car from rolling. The car had to be towed to the Cadillac dealer which they determined a few days later the transmission has totally gone out on it. Their explanation was it was caused to “mechanical failure”. The Cadillac dealer nor GM would back up their product. The dealer offered to take it as a trade for a new Cadillac, no way. Several thousand dollars later, the transmission was rebuilt at my expense. Two weeks after getting the car back with a rebuilt trans the throttle went out ($600). A few months later the tracing sensor went out. After that was replaced the car started leaking radiator fluid and need 2 water pumps replaced at the tune of almost $1,000. This was enough within a few months and less than 80k miles on the vehicle. I recently traded the CTS in on a brand-new foreign made vehicle not a GM product. GM did not back up their product and have not earned my business. For the price and the Cadillac name, I expected more.
The CTS model has huge UNFIXABLE problems with the stablizertrk system. It just doesn't turn off the system, you LOSE power to the transmission. Pulling out into traffic can end with your car being t-boned, and this is without any notice. Getting it repaired has been unsuccessful (Cadillac Dealer Mechanic) they've replaced the system, working on the transmission, now the problem is worse than ever!!! Checked out forums after the fact, this lemon should have been recalled, but hasn't been. 2007 - 2013 models have these issues.
2009 Cadillac CTS 4dr Sedan w/Direct Injection (3.6L 6cyl 6A)
I purchased this car with much excitement, I finally owned a Cadillac after 55 years on this planet. I wanted one since I was a little boy. This car has been a nightmare, repair after repair, and never runs without a check engine light coming on after a few miles. The fuel pump melted pouring gasoline over the exhaust, luckily we weren't killed, they recalled all model years up to 2008, I have the 2009, so even though the part used was the same, no coverage, $1600 out of pocket. The exhaust system fell off twice, battery died multiple times, brakes went out, seats and electronics all went bad after the repeated leaks from wherever, 4 inches of water on floor in back seat, trunk with a foot of water, and dashboard where computers and electronics are housed lots like a waterfall when it rains...car is totaled, mold ,mildew, just a mess. The folks at GM do nothing for you, and the dealer could care less, actually offers to sell me another Cadillac, as if that is doing me a favor...Hudgins Chevrolet Cadillac in Williamsburg, Virginia, stay away from them, they don't care. This car was a lemon, never again with a GM product.
Bought this beautiful car with low miles (6,000 at two years old) and drove it on a long commute for a couple of years. Really enjoyed it, with the exception of the front seats being not as comfortable as they should be. All was well until I neared 100,000 miles, and then....engine issues. Leaking gasket and two quarts oil down when it shouldn't be. Pinion leak (AWD) too. Dealer wanted $2,000 for both repairs. Took it to a great local mechanic who said he had a 2009 CTS on the hoist to replace an engine, which he said he sees too frequently for this model and year. Having previously only leased cars, I'd hoped to drive this beauty for another few years. But, looks like I'll be in for some big bills unless I trade it in. Will miss driving a Cadillac.
