Roof has constant leak when it rains. It leaks through the front side on dashboard/radio, and through dvd player located on roof. We have to cover vehicle each time we hear it is going to rain. I have seen there are millions of other drivers with yukons with this same problem. Checking to see if this would be an issue gmc would resolve for owners of these vehicles? Thank you for your time.

Again, I am writing. I implore you to reinvestigation gmc for rusted brake lines. We replaced ours after they were so rusted, being a camping family, towing a trailer we could have all died. I understand that your office has investigated this and for whatever reason determined it was normal wear and tear but I think that your department is on overload and didn't want to handle another gm recall. Gm and consumers know that the company got away with not issuing a recall. Yes, I am angry at the $800 we had to pay to repair this but I am more angry that after gm was contacted for reimbursement I got no where and they were snarky and admitted as much that they weren't made to be responsible. Again, I ask that you reopen this investigation on behalf of consumers. Afterall, if it was normal wear and tear and an industry wide problem why is it only gm cars. Yes, I live in pa but I live in southern pa where we don't typically get alot of snowy or icy weather. My car is garage parked and only driven about 6000 miles per year. And the brake lines rusted? If something isn't done I intend to pursue this further. [xxx] VIN unavailable information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

When taking off from a stop or at a slow speed the car stalls like its running out of gas, when that happens on the diagnostic center on the car reads "traction active", and then car behind me blows their horn telling me to move, then the car takes off. Its really scary when I'm in the middle of traffic in the intersection or trying to make a left turn and trying to go and it stalls. Sooner or later someone is going to run into the back of me or when I'm in the intersection I will be t-bone and someone is going to get killed or seriously injured. I took it to the gm repair center at art moran 9/10/2015 and they tell me there's nothing wrong. The service advisor reggie garrett ask if their was a certain time it would act like this and I told him it seems like when its hot outside is when I notice it. Then, the very next morning about a half mile into the drive it did the same thing. So I called reggie up and told him it doesn't make a difference if its hot outside or cool it does the same thing, and this is all while I'm on my way over to their repair shop it did this 7 time all at dead stops or slow speeds. Once I made it to the shop I ask reggie to get his tech. To drive it with his scanner plugged in, but he suggested I drive it but when it did it the scanner didn't record it. I going back there this week and on the way I'm going to record it on camera in an effort to document what going on.

After a full day of driving with my child in the car I went out on my own to get him medicine. While attempting to stop at the end of my block the brake pedal felt funny. I went to the next stop sign and attempted to stop and my vehicle wouldn't stop. I ended up rolling right into the middle of the intersection. I realized there was a big problem so crawled back to my driveway. I then noticed the whole underside of my vehicle was wet and now my driveway was soaked with brake fluid. One of the steel lines burst. After I looked at them I noticed they are all rusted and in very bad shape. I now have a mechanic having to replace all the brake lines in the car so that I don't have to worry about what could have happened when driving my 1 year old around with no brakes.

Tl* the contact owns a 2006 gmc yukon denali xl. The contact stated that while driving approximately 30 MPH, the brake pedal traveled to the floorboard abnormally upon engaging. The vehicle failed to decelerate until after the gear lever was shifted into neutral. The contact also noticed brake fluid leaking on the ground. The vehicle was towed to an authorized dealer where the driver's side brake line was replaced. In addition, the transmission oil line was previously replaced. The manufacturer was not notified of the defect. The approximate failure mileage was 54,000.

Recently, my check engine light came on in my 2006 yukon denali xl w/ a 6.0 engine. The diagnostic test showed a gas cap problem. However, this did not fix the issue. Several weeks later, the engine started making what sounded like a clicking sound. Upon further investigation, it was discovered that there was a leak in the driver's side exhaust manifold. While in the shop, the mechanic discovered 2 bolts that were broken on the driver's side and it was found that one of the bolts on the passenger side is broken, but the passenger side exhaust manifold was not yet leaking. The auto shop was able to extract one of the bolts, but has found it impossible to remove the other on the driver's side without pulling the engine. This is a necessary repair because improper exhaust is a direct violation of epa standards. Furthermore, engine fires can result from this type of issue. Upon further research, I have found numerous other gm vehicle owners with a similar exhaust manifold bolt problem. In fact, there is a video created by carquestions on this exact issue. The following is the link to this video http://www.youtube.com/watch?v=0yg6wlbnzgi , gm should investigate and consider a recall of gm vehicles with this problem, not only because it is very costly to the consumer, but is also an epa and safety issue.
