Cylinder 1,3,5,7 in engine has misfires, this enging has the afm and tjevv4/V8 mode is wearing out the engines and causing them to fail. My engine has had the valve lifters fail. My engine now has a tapping sound, and after taking to garage they have informed me this is an ongping issue with this year of Tahoe and problem is very common and they said it is S bad design. I was driving 70mph on the highway when cylinders 13,5,7 started misfiring, car went from 70mph to less then 40 mph and started shaking and studderring, aslnost got tearended on the highway because of this.after garage inspected vehicle they have determined the valve lifters, cam shaft are bad in the engine and have cause the traction control and stabiltrack errors in my Tahoe. So now I have to get the engine rebuilt because of GM bad active fuel management design, (afm) I have been complaining of the issue since my Tahoe had been using a quart of oil every oil change
Our 2007 Chevy Tahoe had been driven for about an hour and then parked for approximately two hours. Upon starting the Tahoe with cold engine and pulling away from the curb there was an immediate smell of something toxic coming from the air vents followed by black smoke from the engine compartment. The vehicle was stopped and turned off and less than a minute later there were flames emanating from under the hood and within a couple of minutes the hood was blown open and the entire front of the car was engulfed in flames.
"takata recall" airbag light is on. My 07 Chevy Tahoe burns 1 quart of oil every 1000-1500 miles" dealer told me this is "normal"?????? it is not normal for any vehicle to burn this much oil in such little time!! Chevy won't correct these problems! there are thousands of people with same troubles. Yet still no recall????"
The contact owns a 2007 Chevrolet Tahoe. The contact stated that the reduced engine speed warning indicator randomly flashed several times. The vehicle drastically reduced speed intermittently. The vehicle was taken to a mechanic who replaced the throttle body position sensor, but the failure continued. The vehicle was not diagnosed or repaired. The manufacturer was notified. The failure mileage was not available.
My truck is consuming lots of oil and gas. Took it for an oil change and they say it was no oil in it after putting in two quarts in two days ago. My truck was saying I had oil but I didnt by the stick. My stabilitrack and traction control light is on and it is running rough. The computer is reading a misfire in cylinder one.

The contact owns a 2007 Chevrolet Tahoe. The contact stated that the instrument panel failed to illuminate as well as the lighting where the radio was located. The contact noticed an abnormal odor inside the vehicle through the air vents. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 155,120.
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.
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.
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 wouldnt 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.
