My chevrolet tahoe, despite regular maintenance per schedule, loses on quart of oil every 2500 miles. There are no leaks, smoking exhaust etc. The dealership told me this is a well known problem of unknown origin. The electrical systems on the vehicle have been a nightmare. The ignition will at times fail to turn off despite removing the key. The cruise control will pop out of cruise mode for no reason and will often fail to reengage immediately. Lithia chevrolet in redding refuses to discuss repair or replacement, stating it is not their problem. I also have a recalled takata airbag that lithia refuses to replace.

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

"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?????

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.

Tl* the contact owns a 2007 chevrolet tahoe. The contact stated that the oil engine warning light illuminated and that the oil needed to be replenished every 1,500 miles. The vehicle was taken to a dealer, who diagnosed that the pistons needed to be replaced and that the motor needed to be rebuilt. The vehicle was repaired but the failure persisted. The vehicle was taken back to the dealer where the vehicle was placed under an oil consumption test for 100 miles and discovered that the vehicle needed a heavier oil. The manufacturer was notified of the failure. The approximate failure mileage was 100,000.

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.

Extreme oil consumption on my 2007 chevy tahoe...have to add oil every time at approximately 1500 - 2000 miles after oil change. This should not be happening. Chevy knows about numerous amounts of complaints on 2007 tahoe's and they do nothing about it. Also have complaints on cracked dashboard...this should not be happening at all. This SUV cost me 50k and we should not be experiencing these problems....help!!!

I recently experienced a known electrical issue for the first time yesterday. I just had my tahoe at the dealer last week for strange clacking noise under the hood. They stated I would just have to wait until it did it again. Yesterday everything went haywire and my tahoe appeared possessed. Door locks, gearing shifting was affected making it difficult to drive and steer due to loss of power steering, which could have caused serious risk to others around me and my two children in the car. Turning to the internet and finding that I am one of what is probably thousands complaining of the same issue makes my extremely concerned that gm is not looking out for its current and future customers. I will be filing a complaint with the attorney general's office, ntsb and now with the state of nc immediately. Not only have we dealt with this issue. We have long dealt with the oil consumption issue that gm continues to say is "normal" consumption. Extremely disappointed in gm and how they are handling major component issues. We also own a jeep wrangler and they are been absolutely amazing anytime we have an addressable issue.
