The contact owns a 2009 GMC Sierra 1500. The contact stated that the vehicle hesitated and stalled without warning. The vehicle was taken to serra Chevrolet Cadillac Buick GMC (189 stonebridge blvd, jackson, tn 38305, (888) 380-6149) where they replaced the fuel pump module, cleaned the throttle body, replaced the fuel pump sending unit, and reprogrammed the module. The contact stated that the engine power was reduced due to lack of communication with the fuel pump module. Shortly after the repair, all of the warning indicators flashed, which had not occurred prior to the repair. The manufacturer was notified of the failure. The approximate failure mileage was 103,000.
The contact owns a 2009 GMC Sierra 1500. While driving 65 mph, the speedometer and the tachometer gauges fluctuated up and down, the air bag and transmission indicators illuminated, and the engine seized. The vehicle was not taken to a dealer to be diagnosed or repaired. The manufacturer was notified and informed the contact to call a dealer. The failure mileage was approximately 47,540.
At around 100,000 miles, the check engine light would come on and indicate low oil pressure. Changing the sensor out did not effect the situation. Changing the oil would help but usually only for around 3,500 miles. The engine was losing oil more than it should. Then at around 129,000 miles, the truck starting shaking because of the engine and the check engine light came on. It was determined to be a cylinder 7 misfire. Changing the coil pack, spark plug, and spark plug wire did nothing. It was determined that the engine was irreparable and needed replacing. Upon research, it appears that this is a fairly common problem among 2008-2012 GM engines with the afm system. GM should absolutely issue a recall and repair these defective engines or otherwise reimburse the owners for the repairs.
Active fuel management failure number 4 cylinder. P0304 dtc. Has a loud ticking noise and a miss on number 4 cylinder. The truck has been maintained and as I researched the problem, it appears to be more likely than not to affect these trucks.
At 80000 my truck is going through 4 to 6 qts of oil between oil changes. As a master technician this has got to be the poorest excuse for engineering I have ever come across with this afm system they have. I know several people that have lost an engine by 100000 miles. With todays technology that's a bad joke on the consumer. With shorter intervals and some additive's I have managed to get to 1 qt every 1900 miles and that's as good as it gets.

Stability control. The stabilitrack warning appears. All of the gauges go to zero, the power locks engage and disengage, the engine revs and the driver loses control of the truck. This is an extremely dangerous problem. The dealership can't find anything wrong because no codes are showing. This needs to be a major recall. It's a common problem, google it and see how many people have the same issue with no resolution. Force GM to address and resolve this known issue.
Lifter failure! expensive repair! common issue on afm 5.3 V8 engines. Driving down hwy. Just had had low oil pressure issues and made necessary repairs the very day before (cleaned small screen that picks up oil to send pressure to dash guage) changed oil at dealership, only to drive truck less than 75 miles and loud knocking in engine occured, truck went into "limp mode" had to be towed to dealership for a full lifter replacement. Again, common problem that should of been recalled/repaired before drivers are left stranded facing huge expensive repair bills.
Excessive oil usage, have had it monitored 3 times per GM. Uses oil every 2 thousand miles, they are aware that these 5.3 V8 are doing so. There is a service bulletin out on this problem, this problem needs to be investigated by our government.
I have regular maintenance done on vehicle from certified GMC dealership. However, a few days ago while driving the vehicle both the engine light and traction control lights came on, causing the vehicle to display low engine warning and losing almost all acceleration. Took it in to dealership, and was charged nearly $800 for repair.
I have the engine with active fuel management and as I was driving down the instate the engine goes in to failure mode. Lifter collapsed tearing the cam up as well. Spent about 3000 dollars having issue fixed with new GM parts only to have it fail again. Called GM and they said they were aware of the problem but it's from faulty parts and it was the customers problem. The engine smokes bad and burns oil and raw gas sits on the piston without being burned off properly.
Driving only 20 mph in the process of stopping. Check engine light came on. Very difficult to stop. Engine ran very rough. After stopping the vehicle would only accelerate up to approx 25 mph. Stopped again and turned off engine. Re-started engine and was able to drive to a Chevrolet dealership with the check engine light still on. Dealership replaced sensor ki.
