What Problems To Look For On Gmt-900?

My 2009 Sierra 1500 is at about 35k miles so I'm about to run out of the 36k mile bumper to bumper warranty. I don't think I'm going to go with an extended warranty as the price is pretty insane. I just don't want to miss something that could have easily been fixed under warrnanty.

 

The problems I'm taking it in for now are....

 

-Lumbar motor in passenger seat is rattling and needs to be secured

-Tailgate is not opening and closing right, somehting wrong with the latch.

- I get a strage rattling/hissing noise from the engine when accelerating from the lower drivers footwell. (going to be hard to replicate for them, my friends thought I was crazy when I tried to show them the noise)

- When I have the air vents set for both upper and lower the system blows gusts of air. I think I read this is a problem with the air diverter which requires the dash to be pulled out. If thats the case I don't want them to fix it.

- I have a small rust patch under the driver side door seal trim.

 

Those are the problems I can find, I read alot of people having suspension issues around 50k miles. I just dont remember the exact problems.

 

What should I be looking for?

My wife always tells me to stop looking and polking around for problems on my vehicles. She must be right cause her vehicles never have to go back to the dealer :cool:

 

Maybe balljoints??

 

Maybe that hissing you are hearing is the air coming thru the drivers door seal in the rusted area( causing a bad seal.)

the HVAC issue with the blend door.. my moms 2003 Caddy had this issue and my Neighbors 2006 Tahoe had it (so I'm betting at some point I will too) the same dealer fixed moms and the neighbors and yeah half the dash had to come out, but they did a good job, no rattles or strange noises after.. I'd get it done under warranty, else it's like $600 (which we paid, out of warranty on the Caddy)

Check your spare tire hoist operation. You didn't post your location in your information, so I can't tell if you are from a state that uses lots of road salt or not.

I have a similar sound that I think may be coming from the speakers. If so, possibly a grounding issue with the stereo.

I am about to do this same thing, I'm at 35k on an 09 Sierra. The only thing I am having an issue with is that mine makes a whurring sound sometimes when I am turning the wheel, this is obviously a power steering issue but I want to make sure I know what other issues people are having as well so I can look it over. All input is appreciated!

      I am sure that was quite the pass experience and not a great place to experience during the winter when the conditions are not good. I've seen video of that pass and also more detailed information and pictures about the wrecks at that one hair pin turn where tractor trailers have flown right off the cliff and I am sure from all the warning signs that you know the exact curve that was !. After all there is a reason why a song was made about Wolf Creek Pass !. By the way and I didn't realize this either when I bought my truck as its nothing I even thought of that would be programmed into the cruise control and this occurs in either the basic or the more advanced cruise that controls your distance behind a vehicle and that is the brakes going down a hill are being applied as soon as the vehicle goes a certain speed over the set cruise speed. While it certainly does force downshifts in the transmission as you found out with cruise on while going down hill, its also dragging the brakes as needed to keep the speed controlled to what the cruise was set to. For me, I find that unsettling simply because I have no concept then as to how MUCH brake input is being used a and just how hot are those brakes getting and the wear factor as well. I can see that system getting a person into trouble on long mountain grades while pulling a trailer as it would not only be standing on the brakes of the pickup without any driver input, it would also be automatically applying the trailer brakes and it could cause a run away unit by overheating the brakes. Its one thing on a shorter hill and if the driver allows it to do its thing but on a long mountain grade is where things could get so out of hand. As someone a while back on this forum said, they had someone following them at night I believe on a down grade and had the cruise set and the person behind them could see the brake lights being energized all the way down the hill. I figured when I saw your comment that you didn't know and would have no way of knowing that your truck was applying the brakes and that you would and rightfully so assume you only used the brakes when you pressed on the pedal to slow down more than the cruise set speed for the slower sharp curves. So its good knowledge to know this about the newer GM trucks, certainly when doing any descending on long mountain grades. In the future try kicking off the cruise and use the the manual mode on a pass to see what that is like as I know myself when I first experienced it I thought no way can this engine be holding me back this well and tried the same hill in manual mode and sure enough the engine was revving way up and still could not hold the trucks speed down like it could in cruise mode.    Fuel mileage, that is where a really low sleek type of car can do better at higher speeds, certainly it starts sucking fuel too but a tall pickup is pushing massive amounts of air and also allowing a lot more air under it and the tow mirrors as in elephant ears pushing through the wind  as well. Driving like grandpa is about as good as one can do when driving one of these if trying to get the best fuel economy they can. I bet these trucks would get the best mileage they can if driven on a freeway in Florida if not busy traffic at a sedate speed and that sea level elevation without hills, vastly different then Colorado !.
