SUSPENSION
I own the 2009 GMC this truck was bought new by me and it only has 41,000 miles on a 13 year old truck it is very well maintained. Both upper shock mounts rusted off and the rear spring shackles have holes in them I had a service center look at it and he said there maybe not enough metal to weld to. The whole frame and cross members are badly rusted and although it is not a safety issue both cab corners are rusting out, and the left rear wheel opening I really feel there is no reason any vehicle should rust so bad and be undriveable.

Brake pad monitor listed over 90% for both front and rear brakes then all of sudden I get warning light that says Service Brake Monitor. I have had this happen twice since I purchased this vehicle new. The dealership has fixed it twice, there were software bugs. I cannot tell when I have a real issue or is it just a software bug.

The Truck has something wrong with the Trailer braking system. with no notice it display "Service Trailer Braking system" in the DIC. This will cause loss of brakes to the trailer and make it very difficult to stop with the trailer. Everything functions properly and at a random moment they will just stop working.

STEERING
In the process of making a right turn my power steering suddenly quit working causing my vehicle to cross over into oncoming traffic. There was an eighteen wheeler that had to make a lane change to avoid a collision. At this time I had a warning light come on stating a problem with the power steering. I was able to slowly drive the vehicle to a local repair shop. The shop had to reprogram the steering module. I know my model had a safety recall for that very issue and I had it repaired at a GMC dealer in 2017. Apparently the problem still exists and I called GMC Corporate and was told that my vehicle had been repaired and was to old for any assistance. I now have no confidence in my vehicle knowing that this problem could occur at any time.

My air conditioning condenser has a leak and leaked all my refrigerant out of the system. From my research and talking to the dealership mechanic, it is a problem GM refuses to do anything about unless your vehicle is under warranty, and they are aware this is a big problem, numerous complaints.

POWER TRAIN
At 101,000 miles I experienced my check engine light and Stabilitrak dash lights coming on and the engine spuddering. I replaced the fuel injectors, spark plugs, spark plug wires, coil packs. I’ve taken it to two mechanics one told me that number eight cylinder was low on compression and the other mechanic told me that he has seen very many of the same motor that I have, with the problems associated with the lifter recall. I don’t know what to do. I’ve heard that the fix is the same part so it’s just going happen again. This is horrible, from a consumer standpoint Especially since GM has known about this since 2007 with their AFM/DFM motors. I would love to hear back from you pertaining to what my options would be for repair and payment. Thank you for your time and have a good day.

UNKNOWN OR OTHER
I live in Corona CA where the temperatures easily exceed 100f in the summer months. I was picking my kids up from school yesterday and the AC started blowing warm air. We had to open the windows which brought in even warmer air into the cab. After a little research online, I found there are numerous Sierra owners experiencing the same issue. 99% of the failed AC is due to a "weak weld on the condenser."(see attached photo) Unfortunately, I could not find any recalls or TSBs related to this problem. With the exorbitant amount of Sierra owners experiencing the same-exact-issue, GM MUST be aware of this issue. This should be determined a safety recall, since this is a passenger vehicle, manufactured to provide safe in-cab temperatures for human beings.
