Used 2015 GMC Sierra 1500 4dr Double Cab SB (4.3L 6cyl 6A) Consumer Reviews

Love the truck but quickly very disappointed

Got my truck in April '15 and loved it - until it got hot outside. I've had two F-150's and a/c would freeze you out. Here in Alabma summer's are very hot. A/C blows hard and very cold, briefly. Then the A/C cooling stops while the hard blowing continues. And since we have such hot summers it feels like hot air blowing on you. It does this back and forth continually. Of course once the truck cools off enough then it not so bad. But it's a good 10 minutes- long enough to start sweating! It's as if the compressor switches off and on while the blowing remains the same. Dealer kept it two days and said it was working normally. I work indoors in an extremely cold business and am a slim guy so when I leave work I'm not overly hot so sweating my rear off on my drive home is unacceptable. Im wondering if the dealers hear this a lot and know it's baked into the design. Either way I will be trading it near years end when prices drop on 2015's. In the deep south with our long, hot summers and high humidity good A/C is critical. UPDATE: A/C still sucks. Truck has always had a vibration at HWY speeds which I attributed to the original tires. Finally after 2 and 1/2 years I needed new tires. Got a set rated the best for All Season/ HWY for my size and truck still vibrates at HWY speeds causing the change in the center console to clink! I will definitely be getting an F-150 when my lease is finished in July 2018. The A/C issue is a real deal breaker for me living in the Deep South.
