A pop was heard under the engine area and immediately after that the car began to idle very rough. It would not run properly and had to pull off the street into a gas station. Inside the car the check engine light and the stabilitrak service soon light were on. After several minutes we turned the car off and then on again, we decided to move again and the idling was worse. The stabilitrak and check engine light were flashing on and off. We began to move but the car was idling very bad and shifting very hard after a few feet of movement. We drove the car to the nearest firestone dealer to see what the problem was. Firestone called to notify us that the cylinder #1 was either stuck/froze and that we would need to open the cylindercover to see exactly what was wrong. The next day firestone notified us that the cylinder rod was broken and that we needed to do a cylinder replacement on the car. The car only had 88k miles and we are the original owners, this is too early to have these problems on a car with less than 100k miles. I found some articles on-line where this is an ongoing problem with gm and that the 20007-08, 5. 3l v8 engines, the first with the flex fuel system, are starting to fail at the 80k plus miles range. We have had our service performed at our local chevy dealer and the car has been maintained well. It is an expensive repair that should not be required on a car with low miles and good maintenance records. Firestone has fixed the car for $2,600. 00 dollars, and car rental fees. This engine failure is a defect and a serious design flaw and we as consumers should not have to deal with this expensive repair without any help from gm if they are aware of this problem and have not filed a formal recall on this model year engine. This could be a dangerous condition if your driving on the highway and the car looses the engine performance at high speeds.
I have an 07 Tahoe and have read from other people that this is happening to alot of others as well. I had my truck inspected at the chevy dealer in lake elsinore. They said it could be a number of things and thought that cleaning my intake system would fix the problem. It was fine for one day then out of nowhere driving on the freeway my stability trac light comes on and the check engine light and says reduced engine power . I had my wife and kids in the truck and find it funny that I guess this has happened to others with different vehicles but the same year GMC yukons. I had the same problem as one and they were near semi trucks. This is not good even worse when you are no longer under the warranty and the dealer can't tell you exactly what it is but wants to try everything. That is wrong. This is dangerous to have happen and even worse when the dealer wants to say they are not exactly sure but find out from reading about others vehicles like mine with the same problem and no help.
