Truck requires a quart of oil every 1500 miles. I knew it was a gas hog but surprised when it burn as much oil as fuel. Please fix this problem.

My strabilitrak and service traction control began flashing on and caused the brake lights to turn off. Then it reads, engine power is reduced. This began in November 201. I have taken it three times to be fixed. First I was told it was the throttle body, then a switch gear, then a fuel induction cleaning service. It is still happening, just twice this week. The engine slowing down while on the freeway proves to be deadly. In reviewing comments in the chevroletforum.com many consumers are having the same issues with the same results (a guessing game) why isn't this a recall?

130,000 miles on this 2007 Tahoe. Had just exited the freeway and was going about 30 mph on a high traffic street (speed limit is 55) when my car started shaking and the engine light turned on, engine stabilizing, brake light turned on, track control stabilizing, every light/sensor turned on as my car was shutting down. The engine was still on and was shaking but I could not drive. I turned the car off for a few minutes and then turned it back on just so I can try to get back to work. Taking it to the shop after work to see what is happening.

The contact owns a 2007 Chevrolet Tahoe. While driving 45 mph, the service engine warning light, traction control warning light, and stabiltrac warning light illuminated. On several occasions, when the accelerator pedal was depressed, the vehicle hesitated and failed to respond. While the vehicle was stationary or parked, it backfired. The vehicle was not diagnosed nor repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 171,000.

The vehicle has a faulty throttle body and throttle position sensor that cause the vehicle to go into "engine power reduced" mode which basically means the vehicle doesn't move. The engine is still running, but the vehicle is inoperable. This has happened to me dozens of times, in intersections, and I have to roll off the side of the road. Additionally, the intake gaskets leak allowing fluid into the engine. The dash cracked. We have also replaced the air ride shocks (ltz model), the connector will wear a hole in the shock. We have also replaced broken motor mounts and tie rod ends. Additionally, the vehicle was constantly running hot and we replaced the thermostat and radiator. The vehicle leaks oil and our mechanic said that it's the rear main seal that needs to be replaced.

My 2007 Tahoe all of the sudden started shaking and bucking while driving with my wife and two small kids (on valentines! wife was not happy). The service engine light came on as well as warning messages saying the traction control failed, check brake system and service stabilink system. It limped to our house and then it stalled and eventually was very hard to start. I took it to the dealership next morning and was told that the #6 lifter collapsed and they needed to check the camshaft to see if that was damaged. I¿M still waiting on the call to see what the total damage is but I was told it was the active fuel management system. I also saw a lot of people's complaints online of the same thing. GM needs to own up and recall this issue. The estimate I got was around $3,500-$4,500 to repair this.

Uses a quart on oil every 1,000 miles but it is not leaking it.

- Mauston, WI, USA

Truck burns an excessive amount of engine oil. I have to add a quart about every 800-1000 miles. I know that this is a common issue with this vehicle and a manufacturer error with the active fuel management control.

- Costa Mesa, CA, USA

Air bag lights came on and sensors need to be replaced I should not have to pay for this being it is a safety issue and it is defect on GMC part.

- Minneapolis, MN, USA

Excessive oil consumption. Quart of oil every 1000 miles. The engine, spark plugs, intake manifold, and sensors are all affected.

- Valparaiso, IN, USA

I purchased my 2007 Tahoe to be the last car I would need to buy as I am near retirement. I am very worried now that it will need some major repairs to correct the oil consumption. Chevrolet should cover these repairs as it is obvious there is a design problem with the engine and thousands of users have this problem. For the enormous cost of the vehicle I expected better. I should have kept my old 1998 Tahoe. It probably would still be running and wouldn't need oil between oil changes.

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 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.
