I own a 2014 Chevy Silverado. VIN: [xxx]. the ac stopped cooling. One day it was ice cold. The next day it blew hot air. I talked to my dealer and they say that it's a know issue and that GM issued a tsb for repair guidelines but have yet to issue a recall. They say the repair is between $1000 and $1800. They said I could get a refund if a recall is issued later on. They said they would look up the tsb number for me, but have not yet to given it to me. Looking at multiple forums I see many owners have the same issues. Several say they got the issue repaired and their paperwork stated "performed pit5337". most threads mention that this is a known mfg flaw with the hose bracket for this model. The flaw allows the hose fitting to crack over time. It appears that GM includes a support bracket with the new hose as part of the repair. That replacement bracket is GM23264893. I have an appointment with my dealer to have my vehicle checked to confirm that my issue is caused by this flaw. The did say that they have had 8 vehicles in for this repair. The dealer is ray Chevrolet in foxlake, il. 847-537-3300. Once I saw how many hits I got on my google search for this issue, I was shocked that there is still no recall. Please help.

I was traveling up an incline when vehicle started jumping. Engine light came on, as well as stability or skid control and when turning on turn signal the wipers came on. Did not feel safe but drove to nearest dealership with vehicle jumping and missing out, about 4 blocks. Diagnoses was faulty fuel injector at 4577 miles on vehicle. After picking up vehicle when repair was done it missed out again but no engine light. Dealership could not duplicate the problem. Hope this isn't going to be ongoing issue.

After vehicle sits in hot sunlight for extended period of time, and ac is ran-- there is a loud "popping noise" from the center area of the dash. The sound is very similar to a rock or object hitting the windshield. This issue has continued and recently took vehicle in for other recall issue and had them check this. The service adviser first told me they duplicated the issue and would have to dismantled the dash for further diagnostics. The vehicle was in the shop for over a week, and they told me the issue seemed corrected. The completed service ticket indicates problem could not be duplicated or determined. The day I drove home from the shop the vehicle made this same noise three times. I will be taking vehicle to different GM dealer for follow up.

When driving at highway speeds between 72 mph +, the vehicle will vibrate very badly to the point where you can not drive so fast. It comes and goes and when it comes back sometimes even at reduced speeds of 65mph the vehicle still vibrates very bad. I have informed GM of my issue and my local dealership and they choose not to do anything. Really, because they don't know what it is. The vibration is so bad that it can numb your body by the end of your drive or distract you enough to crash. I drive up to 9 hours with my vehicle for work and it is very uncomfortable. I am filing this complaint to see if I can get help to stop this issue from happening. A lot of people are also having this problem and from my understanding, GM is ignoring them as well.
