Print this page Notes: Engines shouldn't need a new quart of oil every 500-1000 miles, but for thousands of Suburban owners that's exactly what's happening. Engine oil consumption on aluminum block engines with Active Fuel Management (AFM) is out of control and owners are left looking for answers.

The most likely culprit is an uncovered AFM valve which, in many cases, can be covered under warranty. The problem is the issues don't stop there and many owners have been told by GM just to buy a new engine. Take one guess who they want to pick up the tab.

Ignition does not engage engine when key is turned. Takes several attempts of turning key on, completely off, then on again until engine will engage and start. Stabilitrak light illuminates and goes off every 20-40 miles. Rough shift between first and second gear.

The forward sprag unit broke which ended up not only causing the vehicle to come out of drive while we were driving but also caused significant enough damage to the transmission to requite an entire rebuild. Faulty transmissions are a very common issue with this vehicle, and the Tahoe, Yukon and because the company refuses to back their products and recall the issue, it ends up becoming a huge financial burden on a family. Thankfully there was no one following directly behind us when this happened or it could have been much worse. Chevrolet needs to take note and stand behind their products. Consumers have a right to expect a quality vehicle that should last well beyond 100K miles without requiring this kind of major repair. Note that GM is so aware of this safety problem, they actually updated their input sprag on later cars to make them stronger. Thats right, they have updated the component but refuse to recall the ones already in vehicles that were weak. The transmission shop that rebuilt my transmission had the exact same issue on the vehicle that followed mine. This seems to be a pattern with GM that the NHTSA should look into.

Like to place a formal complaint regarding the oil consumption for 2007 Chevy Suburban and the horrible quality of vehicle. A few months after purchasing the vehicle the transmission gave out. I've been having problems with oil consumption and its horrible. I believe that Chevy should stand behind their product and do a massive recalls for these vehicle. Again, Chevy should stand behind their product. There are so many reviews about this same problem. Obvious there is a problem. Will never buy a Chevy again nor will I recommend Chevy vehicles!!

Transmission stopped working while driving had been slight vibration several month prior which was reported to dealer-he said wheel balance-did not help only 1st and 2nd gear worked. Local dealer quoted $2,800 to replace. Dealer had the car for over a month.GM offered to pay 45%. I would pay $1540. When picked up car I had to pay $2300! told the warranty from GM caused the price to go up. The car still has a vibration. A car with 80,000 miles should not need a new transmission.

  • 58,000 miles
On two occasions an error message that read "service 4 wheel drive" appeared on the display. I mentioned this to the service department while there for an oil change, and was told that everything checked out okay, and that I should drive the vehicle in 2wd, not auto. Also, I have been having a transmission slippage issue that started between 50,000 miles and 58,000 miles and was very sporadic. When starting from a dead stop (stop light for example), the transmission wouldn't engage as I pressed the accelerator. After 10 to 15 seconds of pressing my foot on the accelerator, the transmission would finally engage and the vehicle would move slowly with the engine revving. I mention this to the dealer when the vehicle has approximately 58,000 miles and I'm told that they will need to keep the vehicle for a few hours and there is a cost of $120 plus tax to perform diagnostic testing. As my schedule did not allow for this that day, I left. The problem was very sporadic at this point. At 63,000 miles I am driving over a mountain pass and the display reads something along the lines of "transmission overheating". I pull off the road and wait for it to cool, then make my way home. I entire trip home the transmission is slipping between all gears and shifting hard in the higher gears. I take it into the dealer for diagnostics the next business day and I'm told that I need a new transmission. I am advised by the dealer that there is "no external cause for this failure" and " the inner mechanism of the transmission has fallen apart and cannot be repaired". my powertrain warranty ended 6 months ago, so I face a $3,350 bill for this repair. After I complain to GM customer assistance, they agree to pay 30% of the repair and 5 days of the rental car, but I feel they should pay the entire amount.

My Suburban wont shift or move in drive or in 3rd. It will go in to 2nd and 1st and reverse. It just revs up when in drive. I was reading online and found several other people to have the same problem with this vehicle. This should be a recall on the transmission or defective parts causing this in the transmission.

I was proceeding from an intersection and turning left, I reached a speed of 15-20 mph and there was a "bang" and a "clunk" and the power to the wheels was gone, I coasted to the roadside and was unable to put the car in "D" drive or "3" it was as if it was in neutral. I was able to limp home using 1st and 2nd gears. Vehicle was towed to dealership for a transmission replacement due to the failure of the forward sprag component.
