2008 Cadillac CTS: check engine light

Filed Feb 29, 2020 · Engine, Fuel system · 35,000 miles · NC

The car only has 35000 miles on it. The engine misfires constantly when giving gas especially if your going up hill and there is more load on the vehicle. After I had $5000 worth of work to fix the problem at a cadillac dealership. They couldn't fix the issue so they came back and said that we needed a new engine. We told them over and over again that we don't think it's the engine but they guaranteed us the new engine would fix the problem. So another $5000 later and still not fixed. The vehicle idles fine, it only happens while driving. The check engine light eventually comes on indicating misfires in 2 cylinders

February 14, 2020 is just the last date it has happened on. It's happened approximately 30 times. For the past two years if you don't just ease on the gas the reduced engine light and traction control light comes on and the car will not go over 5 m.p.h. I have read several hundred articles online on different websites with people describing the exact same thing. It almost got me hit on the ms. River bridge the other day. If u have to go up any type of incline it does it also. I was accelerating slowly as I possibly could going up the small incline on the bridge that connects louisiana and mississippi. All of a sudden the reduced engine power light came on and I could not get out of traffic that was doing approximately 55 m.p.h. And my two year old grandson was in the backseat. The only way to fix it temporarily is to get off the bridge because there is no where to pull to the side of the bridge. You have to kill the car for a few seconds and recrank it. I've had mechanics look at it and I've had it hooked to the computer at o'reillys. No one can tell me anything. But if it weren't a safety recall why would almost 1,000 vehicles that I know of be doing the same thing. You can google it and see that I'm telling the truth. Lots of these cars have the identical problem. I'm currently looking for a newer model between 2014-2018, but I'm afraid of having the same or a similar problem. This is definitely a recall. But it seems to me that you all do not want to do any recalls on these cadillacs. I've been to lots and lots of websites and I have not found anyone who's been able to figure out the problem. Even the ones that have had it put in the dealership have still yet to figure out the problem. It has to be electrical or one or more sensors malfunctioning. Thank you for your time.

Car has failed emission testing for 2 consecutive years since I purchased it. After driving for the better part of a year I took it to a dealer in 2018 and explained that check engine light comes on and off persistently. They tested emissions and said it passed. Again in 2019 it failed emissions again and the dealer provided a diagnostic test which indicated that time chains needed to be replaced. Estimate for repair $3900.00. In short problems have existed for approximately 3 years. This complaint is correct from previous filing number:11174923

My sensors all came up, saying they were bad, I replaced them and the check.engine light is still on. I was told its my timing chain and that the recall just expired. I never received a notice of a recall or I would have had it done before it expired. I was driving on the highway and all of a sudden its bogging down and lagging when pushing the gas and the check engine light came on.

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.

I have a cadillac 2008 cts with 24,000 miles on it. The check engine light came on and I took it to my local cadillac dealer. They stated they could not fix the problem and I had to take it to the selling dealer, don massey cadillac. Problem: the check engine light came on and I immediately took the car in. My local dealer, allen cadillac in monroe michigan stated there were two problems. The timing chain was stretched according to then and the cam and crank shaft were defective. The car is currently in service. I was told by the service tech that this is a common problem with the 2008 cadillac cts and that dealer had seen over a dozen cars with the same problem. Gm has not issued a recall. When I took the car to don massey cadillac (selling dealer), there were six other cts cars in for service at the same time as mine. Although gm is supposed to fix this under warranty, why have they not issues a recall? This is an over $50,000 car with 24,000 miles on it and it will have to have the engine rebuilt. This is the second major repair to this car. This past december, a clip that holds the wiring harness in place snalled and the wiring harness got wound up around the fan and was torn to shreds and had to be replaced. With this many major problem on a car with 24,000 miles (I put on all 24,000 of those miles), what is in store for be when the car has 34,000, 44,000 and beyond miles on it?
