CarComplaints.com 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.

Customer has a 2007 Suburban, the steering angle sensor is faulty causing diagnostic trouble code C0455 and traction control inoperative, tested sensor directly to verify fault, the part is no longer available from GM nor aftermarket, it is my professional opinion that there should be a viable part number available from the vehicle manufacturer as this is causing a safety hazard. I-??ve reached out to GM corporate and have yet to receive a response. Questions or comments please call [XXX].

I started my car and the brakes were gone and the steering wheel was locked up. I turned it off and started it again, then the brakes would lock up and there was no power steering. I waited a while and tried a third time, it made a power steering machine noise and was back to normal. I was afraid to drive it because I didn't want to cause an accident if it happened again. I had it towed to the dealer. The dealer could not reproduce the problem, therefore could not use my extended warranty to fix it. I paid out of pocket for a new power steering pump, because I will not drive it if there is even a chance of that happening again. It's too much of a liability.

The contact owns a 2007 Chevrolet Suburban. While driving 10 mph, the power steering spontaneously failed. The contact stated that this failure could cause a crash. The dealer installed a rubber boot on the steering column, but the failure recurred several months later. He took the vehicle back to the dealer, but they could not duplicate the failure and provide a sufficient remedy. The failure mileage was unknown and the current mileage was 50,000.

My wife was driving this morning and suddenly the engine stopped working and the steering wheel locked. Thank god she was driving in slow speed and could stop the vehicle and avoided a crash. It happened right before she had to turn left but the steering wheel locked and she went straight. She was scared a lot and what if this happened on the highway. Yesterday we have serviced the vehicle at the dealership. There was some recall and they updated the ECU on the vehicle.
