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.

Our 2007 Suburban lurched forward, and doors locked when my wife started it today. She said it also 'felt like it wouldn't go' she also stated that 'the steering locked up' and that she was scared to take it on the road from the store she was at. In the last few months we noticed 1) using excessive oil between changes 2) radio, and dash lights quitting 3) ac working intermittently. In the last 3 weeks we've had 1) the stabilitrac/tcs/check engine light come ON2) hard shifting between 1st and 2nd gear 3) abnormal idling 4) car lurching when started and doors locking on their own when this happened 4) vehicle steering locking up 5) and sluggish acceleration. 8/29/11--vehicle is at dealer for the 2nd time for the check engine/tcs/stabilitrac light....many more have had this problem on edmunds, however dealer wasn't interested in the details unless there was a fix, however I had not completed reading all of the complaints yet...
Tire pressure monitoring system was problematic for years. The display would light and message center would indicate all tires were low when none were by check of accurate gauge. This problem has finally been addressed at least temporarily. Check engine lights stay on. Vehicle has been to shop and dealer on multiple occasions. Tests have been run and the codes reset, to no avail. The check engine light is on and vehicle performance seems normal, however, the warning light remains useless for any "real" problem. Please consider the low mileage (currently 18,224) when considering problems.

2007 Suburban ltz battery has been completely drained 2X within one month. Once after having the doors and back open for approx 10 min and the other at a car wash while the staff cleaned the inside of the vehicle. ( approx 10 min). First time dealer blamed the cold and the lack of driving at the time, had the battery tested and the battery is completely dead. Will be taking to dealership tomorrow. Reading the reviews and am astonished that there are so many complaints about the battery drain issue. We purchased this vehicle as a family vehicle, but am very concerned with its reliability. This is a huge issue for a family with children.
No crashes or injuries. On 2 occasions, with the ignition off and listening to the radio for about 10 minutes, the vehicle failed to start. On another occasion was cleaning the interior with the doors open and interior lights on. The vehicle failed to start. Drove the vehicle a short distance after recharging the battery. Vehicle failed to start for return trip. Took vehicle (2007 Suburban ltz to dealer for an electrical system check. They reported that everything checked out ok. Had another incident of nostart trying to leave home during a snow storm. Finally replaced the battery and have had no problems since. Range of dates is from Jan 2008 through Jan 2010.
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.

Car does not start. Completley dead battery. Easily jump starts.alt shows 14.5 charge after jump..thishas happened 6 times.T ook to dealership twice. Hey say - negative battery cable..
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.

Travelers in subrogee of clifford boyer: Mr boyer's vehicle caught fire and suffered a total loss as a result of an electrical defect in the GMC vehicle.
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.
