general problems of the 2011 Chevrolet Suburban

Engine light on vehicle runs rough/sputters while going down road. Took to 3 mechanics including gm dealer. All stated emissions codes. 1st mechanic replaced purge valve. Light came back on. Same mechanic did smoke test and replaced purge valve stating it must have been faulty. Light came back on. Chevy dealer replaced purge valve. Light came back on. Last mechanic replaced fuel sensor. Light came back on and they stated it now needs a purge valve. In addition, dash stability light comes on but does not go of when button pushed. Dvd player also seems to be constantly whirring. However, main concern is still the engine light that no one seems to know how to fix after I've spent over $1k for several purge valves, smoke test and fuel sensor. These problems ongoing for over a year and no one is able to resolve!.

Tl- the contact owns a 2001 Chevrolet Suburban. The contact stated that while driving down a mountain, the brake lines fractured. The contact had to apply force to the brake pedal due to the failure as the vehicle had gone through a stop sign. The contact was able to coast the vehicle into a parking lot. The dealer dean patterson Chevrolet, 101 pleasant valley blvd, altoona, PA 16602, (814) 942-2222 indicated that there was extensive rust, corrosion and the brake lines needed to be replaced. The manufacturer was notified of the failure, had not issued a recall for the failure but had issued a TSB sb-13-05-22-001. The approximate failure mileage was not available. Dyd.

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.

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.
