2007 GMC Yukon XL 1500: check engine light

Filed Oct 16, 2017 · Engine · 44,060 miles · PA

The check engine light came on along with the service traction control and service stabilitrac lights while driving on the street near home. The truck immediately loss power and I had to limp back home. After getting the vehicle to the dealer, I'm told that the engine has a collapsed lifter in cylinder seven. I don't understand how an engine can experience that type of failure with only 44.000 miles. I contacted gm and their stance is regardless of low mileage, the vehicle is out of warrantee. This issue presents a serious hazard, because a failure like this, if occurred on a highway could cause a catastrophic event with the sudden loss of engine power. Not to mention the financial burden as it cost me $3700 to have the engine repaired. In checking consumer complaints, this is not an isolated incident. The gm 5.3l engine is notorious for this malfunction. When talking with a gm corporate rep I stated, I believe this to be a design flaw, or defect part, but was blown off because I'm out of warrantee. What happened to standing behind your product?

Stab, ABS light and engine lights either going on one at a time or simultaneously. Car wouldn't start & when it did all of the dashboard gauges were at "zero" car seemed off but drive-able--gas, MPH, RPM, gas/oil gauges remained at zero while driving. Later that day when car was restarted-the gauges were at normal readings. Stabiltrack light keeps going on & off. Electrical doesn't work well, almost every power door has failed & actuator has been replaced, rear back hatch door will not open & we have no access to our cargo/trunk area. Keyless entry works occasionally. Interior and exterior chrome handles have sharp edges.

While driving today at a speed of 55 MPH in somewhat heavy traffic my service traction control and stabilitrack indicator came on as well as a message on the dash saying the same. At which time my vehicle came to slow down and I lost power. I pulled over and and shut the car down and upon restart noticed that not only did white smoke come from my exhaust but the car had a rough idle the same indicators were still on and the engine light had now come on as well and was flashing. I was able to make it home with a rough limp however when I came to a stop felt as though the car was hesitant to keep running or take off. When applying gas there was a thump from the rear wheels like the transmission was not sure how to engage.

I own a 2007 gm yukon xl. In or about may-june of 2009 the car began running badly and smelled of gas. I returned it to the dealer (sun pontiac gmc of wantagh, ny) and they said they corrected the problem. It happened again and time again with the check engine light appearing and onstar calls to see if I was okay. Many reports from onstar also confirm this. After many trips to sun pontiac their service department had refused to issue me a repair order because yukons were having explosive conditions, especially mine. I called gm and they said they never had any such problem and referred me to another dealership where the same problem occurred again. I was ordered not to drive the vehicle and have it towed from my home because of the same explosive condition. Since june 2009 I have had over 300 phone conversations with gm. I personally witnessed the entire rear end undercarriage of my vehicle in pieces. I have read and been told that it was a manufacturer defect that even after they replaced harnesses, gas tanks, tubes, gas lines etc. It could not be fixed. The last words out of the service department at sun was that " I wouldn't drive that car if I were you because it might blow up". I knew that gm would never admit to any of this so I taped most of my conversations with all of their head officials and stored numerous copies with two separate attorney's, my family and one cousin who works for the media in case anything were to happen. It was admitted to me a gm that this was not the first time and it wouldn't be the last. I have taken my yukon off the road and parked it away from anything flammable with very little gas in the tank (well, that was how gm left it. I have proof that general motors is fully aware that yukons might start blowing up yet I haven't seen a recall and I have a $46,000.00 pile of rubbish in my driveway.

The check engine light came on, all the lights on the gauges went out, the traction control went out, the brakes started pulsating and stopped the car all by it self. This all happened after the incident that I described in complaint (odi) # [xxx]. *tr parts of this document have been redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
