Example complaints

“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. …”
NHTSA complaint #11364820, filed 2020-10, 100,000 miles“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.”
NHTSA complaint #10616980, filed 2014-07, 66,490 miles“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.”
NHTSA complaint #10615532, filed 2014-07, 1,000 miles“Engine idling low, hesitant at low speeds. Changed gas, no change in how the truck was running. Engine light came on, took to dealership. Replaced spark plug that was misfiring due to oil contamination. Cleaned fuel injectors and throttle body, replaced valve cover to prevent this from occurring a third time (has happened twice already and in the last nine months). Total repair $1173. Not covered by warranty.”
NHTSA complaint #10721821, filed 2015-05, 90,396 miles“Engine was idling low and hesitating at low speeds, then engine started running rally rough. Service engine light came on, changed gas in vehicle, problem continued. Engine running really rough and service stabilitrack light came on. Took truck to dealership and was told the first spark plug was fouled due to oil contamination and that engine and fuel injectors and throttle body needed cleaning. This cost $475 and was not covered by warranty.”
