I have an airbag failure on my dashboard, the airbags are not working. On saturday 11/21/2020 the driver side door kept saying door was open when it was entirely closed. Later on that morning, the passenger seat had cold AC while the rest of the car was throwing hot air on it's own. Because the car kept saying the passenger door was open, inside lights did not turned on. Replaced the door module and issue not fixed. Battery drains at least twice a day. Had to replace the engine oil pressure sensor multiple times and it still goes off randomly while driving and fix itself. This car it's used only to drive less than 10 miles per week. It is so annoying wiht this issue just to get it out and back home. I replaced the battery, alternator, oil pressure sensor, pasanger door sensor, AC filters all this in less than 1 year and it's one thing after another. Very disappointed.

My issues started almost two years ago when dropping my child off at daycare. I was on the highway and noticed a loud ticking noise coming from the engine. At first I was not sure what it was until I pulled in the daycare and it was evident something was wrong. At that point the stablitrak and traction control light started flashing. I had to have the vehicle towed because I tried to move it and when I put it in gear it jerked so hard I was scared the engine blew. I took it to the certified chevy mechanic, cylinder 6 misfire. We replaced the plugs, coil packs etc, trying to see what the issue could be. He finally replaced all 16 lifters, cam, head gaskets and oil pump as well. Once he got it together, it was still a misfire on cylinder 6. He took it apart to look at the pistons, they were fine. The top of the motor he practically everything brand new on it. The chevy dealership are aware of the lifter issues with this vehicle and blatantly told me, I need a new engine or could purchase a new vehicle. Still no resolve as of june 23, 2020! Please issue a recall on this as so many of these vehicles have this issue and it's not fair to us that they designed the engine so poorly.

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.

Our extra third vehicle tahoe, is driven on the weekends or when the entire family is going out. On october 10th, we notice a knocking noise while driving or sitting idle. We took the car to the dealership on october 11th and was told we needed a new engine or to buy a new vehicle. We took the car to a local mechanic on october 13th for a second opinion and was told the car was 2 quarts low in oil. Which was a major red flag to the mechanic. Now, we have to purchase a new engine.

The oil level low light came on in the car. I took the car to my local mechanic. He also has a 2007 tahoe. He told me to take the car to the local chevy dealer. He has seen this many times in the 2007 tahoe, apparently they burn oil and it is due to a defective design of the piston and piston ring. The dealer paid for his tahoe to be fixed. I was told that gm now uses a minimum participation financial calculator and gm would only pay for 45% of the cost to repair, leaving me with a $1,705.10 repair bill. I was able to get the repair cost down to $850. However, this car is defective. I have not even finished paying for the car and the dealer is telling me I need a new engine due to a design flaw. I think gm needs to do the right thing here and repair their flawed 2007 tahoes. Gm clearly knows of the flaw as they redesigned the 2008 piston and piston ring.
