Air conditioning system went out. Dealership found that the line set between the condenser and compressor failed. Dealership stated it needs a bracket to fix or this will keep happening. Approx. $700 to fix and not covered under vehicle warranty.

Air conditioning hose between condenser and compressor failed. Needs a bracket to hold it. GM knows about this but has not called for recall. They charge $700 to fix. Virtually all 2014 Chevy and GM trucks are affected. I am very disappointed with GM. Truck had only 60K miles.

Air conditioning went out in April 2017. Dealer replaced schrader valve and reloaded refrigerant. Failed again in a few days. Dealer then told me GM had a design failer on air conditioning unit and did a nationwide recall of the A/C condensor. My air conditioner was not repaired until August 4, 2017 when the dealer got the A/C condensor. I not only paid $198 for the original fix, but also $350 for the final fix which I continue to monitor. All because of a design failure attributed to GM. Why is this my problem and why do I have to pay?

Vehicle shakes excessively at highway speeds. Shaking is so bad that it causes seatbelts to lock. Multiple sets of tires and balancing have not solved the issue.

Started my truck on 7/30/17 and had no cold air blowing from the vents. Drove it for the day and still nothing. Took it into the dealer on 8/2/17 and received the diagnosis of a cracked ac condenser. The fix is not possible for 6-8 weeks because there is a national backorder on a replacement condenser from GMC. This is a design issue and not a ware and tear issue. The dealerships want the owners to pay for it even though their design is at fault to begin with.

I currently own a 2014 GMC Sierra 1500 with 55,000 miles.on May 15 2017 the vehicle was diagnosed with needing an ac condenser at greiner Buick GMC because the vehicle had stopped blowing cold air. We were told the part had to be ordered and they would call us when it arrived to be installed. That following day we received a phone call from the parts department at the dealership stating that the ac condenser is unavailable and they did not have an eta because the part was backordered. About a week had past, and being frustrated with having no ac, living in 110 degree weather and driving this vehicle with a 2 month old and 4 year old child, I was desperate to have it fixed. I contacted General Motors directly to see what the issue was with the part and see if they could help me. After speaking to the representative, I got no answers besides they are "working on it." She told me this was a nationwide problem and they are trying to get the part available from the manufacturer. I told her my situation and the safety issue with no ac and the climate I live in and she told me they couldn't do anything or expedite getting the part. My husband and I looked into getting an aftermarket condenser and those too are unavailable. We did research and there are tons or complaints about the ac condenser breaking in the GMC Sierra and Chevy Silverado models and GM has done nothing about recalling it. This part rarely fails in a vehicle, unless it is damaged. It is clear that this part is defective, and is unavailable even to be replaced. This is a huge safety concern and GM needs to address this. Still, 2 months later our vehicle still has no ac and GM has done nothing to help us.

Air conditioner fails because of faulty condenser, this is a widespread problem since a replacement part is not available worldwide because of the demand. The dealerships are sending vehicles to 3rd parties to have the condenser repaired. This repair is not covered by any warranty.

Air conditioner not working. Ac condenser has developed a leak. In doing research I discovered that this is a common problem for GM vehicles of the model and the like, but GM has also pulled all condensers from the shelves but will not do a recall to address the defective condenser.

When driving at higher speeds (50+ mph - typically on the highway) the entire truck shakes: The console, steering wheel, etc. You can feel it in the seats and the floor boards. It feels as though the truck is going to go out of control or break down at any moment. Over the past two years, we have had our entire truck suspension, alignment, brakes/rotors, etc inspected numerous times and were told more than once by GM technicians that this vehicle performs under acceptable conditions according to General Motors, even though they agree that it does not feel acceptable. My last inspection was today and I was told the same thing.

Air conditioner started blowing hot air in November/December 2016 at or around 50K miles. In June 2017, paid a GMC dealership to diagnose the vehicle. Results show a condenser leak.. contacted GM customer care dept. (spoke to beth). Beth confirmed the diagnosis, informed me of the backorder, then informed me that GM would not provide cost assistance for the repairs.

45,000 miles. Air conditioner starts blowing warm air about a month ago. The following week, take the pickup to the local dealership to diagnose the following. Condenser is leaking. Informed that the part is on a national backorder and they will call me when it comes in. Three weeks and counting so far. I live in the southwest so the temperatures have been very hot lately as this is the hottest part of the year.

A/C condenser failure. Repair part is on national backorder. Estimated arrival time is 10-12 weeks. Texas summers create a very hot vehicle. Children in car seats without air conditioning is dangerous when sitting in bumper to bumper traffic. Rainfall requires either the windows get rolled up or children get pelted with rain drops on the highway. Neither are acceptable.

A/C condenser went. GM has not issued a recall. There is a national back order on the re-designed condenser. People are being forced to wait months and are going without A/C. GM claims that they are aware and are working with two manufacturers to get the new part made and shipped to dealers. Please see documentation of chat session with GM rep.

A/C condenser issues across many different vehicles have caused the part to be on back order in some cases for months. To me this sounds like a defective part that warrants a recall. A can of refrigerant can leak out, for me, in the matter of just a few weeks and I took it in and was informed of the condenser leak. This has been an ongoing thing that many others have complained about. I understand that this does not qualify as a safety issue but others have stated this is the process to conduct a recall investigation if warranted.
