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.

No crashes or injuries. On the indicated date I had the engine turned off with the keys in the ignition, listening to the radio. After a short time approximately 10 minutes, I discovered that the car battery was completely drained. I have been careful not let these incidents occur again but it has repeated at least 6 times. The most recent time was when I had a flat tire replaced and the tire service tech attempted to reprogram the tire pressure monitor system at which time, the battery was drained immediately. The reprogramming was impossible because the battery would not provide electricity to complete the TPMS. I followed the owner's manual's instructions┐ and had the same results, a dead battery and unsuccessful attempt. I now have a useless TPMS and the danger of getting stranded with a dead battery. The dealership offers to attempt to fix the problem starting at $99 +. a new vehicle should be free of these types of defects. I should not be paying for the repair.

Every 4-5 months the battery goes dead. It's as if the lights or something was left on but once we get it started and check everything there has been nothing left on. After getting it started it will go another 4-5 months and be completely fine then all of the sudden it will be dead again. This has happened 5-6 times over the last three years.

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.
