Excessive oil consumption. I see this is a common problem on GM vehicles and it affects both my 2011 Suburban and 2012 Silverado with 5.3 flex fuel engines. The Suburban is more noticeable since we use it for long road trips. The truck is mostly city driving. I believe this to be caused by the afm and PCV. I will be installing the upgraded valve cover in hopes of preventing a major engine failure in the future. It would be nice if GM recalled these engines with an adequate fix. I only notice burning oil on startup coming from the exhaust. Current mileage on the Suburban is 104,000. I have not touched anything in the engine bay or cable covers yet. Please respond quickly if I should not. Thank you, [xxx] redacted to protect personally identifiable information pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
The contact owns a 2011 Chevrolet Suburban. While driving approximately 65 mph, the rpms reduced to 0 and the instrument panel indicators illuminated. Additionally, all the doors unlocked and locked and the radio began to turn on and off. The contact pulled over to the side of the road and turned off the vehicle. The contact had to wait a couple of minutes before she were able to restart the vehicle. The failure occurred approximately five times. The contact called rainbow Chevrolet (located at 2020 w airline hwy, la place, la 70068, 985-718-4683), but the cause of the failures could not be determined. The vehicle had not been repaired. The manufacturer was not made aware of the failures. The contact stated that the failures were related to NHTSA campaign number: 14V827000 (electrical system). The approximate failure mileage was 141,000. The VIN was invalid.
My vehicles engine shuts off while driving. All electrical in the car including power door locks start to open and close when engine shuts off and powers back on. Extremely unsafe especially when driving with all my children in the car.
Oil blow by when drops to 4 cylinders, took to dealership while under warranty to put in a bypass valve to "see" if will fix, didn't so next step was to have bottom half of engine rebuilt which I had to pay for out of pocket which then in turn ended up blowing up my whole engine either because the lifters got to hot & warp(which was the cause originally for the oil consumption as the heads) or the fact that the dealership sanded the heads which could have caused metal shavings to disperse through the engine. Either way the issue began while vehicle was under warranty as had been dealing with dealer for 2 years when issue began to the date engine blew. Had dealer put back together to take to another dealership for 2nd opinion and they also said it's been a know issue with the Suburban from 2007-2011 but is not a recall as of yet - I want my money back, I should not have had to pay for the "see if this works part", the bottom half of engine to be rebuilt, & then a new engine when GM & dealerships know this has been an issue for 4 years!!!! totally not acceptable. I'm not even including all the time & gas taken as had to take vehicle to dealer to test oil levels every 1,000 miles for 2 years - again when a known issue. Have paperwork from dealers on hand.

While driving on the highway I was using the cruise control and the car began to increase in speed without my control. It went from 65 to 90 in a few seconds and I had to slam on the breaks to get it to stop. This has happened several times. Also we can never let the gas get lower then a quarter of a tank or the car just shuts down like its empty. Sometimes the engine will just rev up for no reason and other times it doesn't accelerate properly. You can push the gas and it feels like the speed is delayed but then will catch up.
The accelerator hesitates when pressed. The car does not move and will then accelerate rapidly when at a stop and trying to accelerate through intersections. Dealer could not duplicate for repairs. Recurring issue. Also has a popping or clunking noise in back passenger side. Dealer has duplicated but not repaired.
