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.

Takata inflators... still no repair info. Also, as noted in many other complaints, my passenger side airbag/dash cover has a huge crack all the way across. Needs to be fixed. Also - we have electrical issue after electrical issue. When will they address these issues?

Safe lite auto glass placed polyeurethane glue on the rear window auto defroster metal contact to the rear window of my Chevy 2007 lt Suburban. I hit the remote starter and allowed the car to run for 9 minutes, the vehicle will auto shut off after 10 minutes. My daughter smelled smoke in the car so I inserted my ignition key and I rolled down the windows. I then backed my car out of the garage, pulled out of the driveway and my rear window exploded into pieces of glass everywhere. I called the police, filed a police report, filed a claim with my insurance company (geico, ref claim # : 0501768800101053) where the claims adjuster found that the metal contact did cause a chemical reaction with the polyurethane glue as the cause.

For the last year I have been attempting to get GM/Chevrolet to pay for my faulty speedometer and since there was no official recall other then the extended warranty and my vehicle was not list although it did receive the same manufactured part as the previous year models, I too should have been covered. Special coverage adjustment-#07187A I would like to have my vehicle fixed since a: GM spokeswoman [xxx] - said Friday that the agreement "clears the slate" between delphi and GM "and resolves a certain group of outstanding warranty issues." She said the agreement covers as many as 50 warranty issues; the settlement refers to at least 43 warranties. The major issue resolved involves 1.1 million electronic parts that are part of instrument clusters, according to a heavily edited version of the agreement that has been made public. The instrument cluster is the electronic brain behind the instrument panel on the dash. With the agreement and an improving relationship with delphi, GM hopes to save $2 billion annually in parts costs. As delphi exits several businesses, GM will represent a diminishing share of its revenue -- down to a quarter or less than $5 billion by 2010. Delphi attorney jack butler said the agreement saves delphi "hundreds of millions of dollars in potential liability." Defective parts replaced under the deal, GM will receive $47.5 million to replace defective electronic parts and delphi will provide 1.1 million new parts at no charge through 2014.

The contact owns a 2007 Chevrolet Suburban. The contact stated that the air conditioner motor failed to operate.

The vehicle intermittently exhibits a dead battery. This happens regardless of whether the vehicle has been driven for hundreds of miles or none at all. At seemingly random times, we go to start the vehicle and the battery is dead. We have had the battery, alternator and cables tested. All tested good. We also notice that around the same time this problem started occurring, that engine noise could be heard through the vehicle speakers regardless of whether the stereo is on. This also occurs at intermittent intervals. We have taken to the dealership and they cannot reproduce the problem in shop in order to troubleshoot. Parasitic draw test is negative due to the fact that the problem is intermittent and not constant.

Our vehicle started to use between one quart and 2 quarts between oil changes. At sometime before this the heater stopped working on the windshield washer fluid. The dvd player stopped working around 75,000 miles. At 79,0911 miles the service air bags light came on. We are not new to owning Suburban. This is our fifth one. We have always been happy with them, but this one has way to many things that are not working properly. We would like to hear from you regarding resolving these issues.

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.
