Air condition blowing hot air! leak in the condenser.
There is a leak in my air conditioning condenser. when brought in for service i was told there is a nation-wide backorder on the condensers. i then had to bring in my truck for a ignition coil failure and was told by the dealership that they have been seeing a high number of leaking condensers and cannot get parts. while not a safety issue this is an extremely costly fix on a fairly new vehicle and seems as though there is a high occurrence of failures and this needs to be brought to the attention of the public and gmc.
At 70,000 miles, and 30 months after purchasing it new, the air conditioning stopped working due to a faulty condenser. after investigating this problem i found out that there is an extremely high failure rate of gmc trucks for the same exact problem. it is a well known defect per several gm dealers who are left to deal with the problem. a bracket to secure the a/c line was never installed when vehicle was built, causing movement in the line which eventually can ruin the condenser, ac line and compressor. i asked gm dealer to fix under warranty but was told that the repair would not be done under warranty. this is unacceptable, as the defect is widespread in many of their light trucks. i was forced to repair at my own expense when this is an obvious defect
I am writing to inform that my sierra has what is know as the"chevy shake" in which it vibrates in speeds ranging from 65 to 80. please help with this issue, as it's only a matter of time before this vibration fatigues a structural component. thanks.
My vehicle has side board steps. the tread pattern is such that when wet or icy the step is a virtual skid pad. when you place weight on the foot on the tread it immediately slips out from under your position. last year i broke a foot when i slipped and this year it was an ankle. tread design needs to be improved and turned 90. as designed there is no traction protection. just the opposite, it promotes lack of traction resulting in slipping and falling.
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.
Takata recall air conditioning condenser went out and the parts are on back order the dealership even explain that thousands of these model trucks are having the same issue
The headlights on the truck are not as bright or as effective as they should be when traveling in the dark. i am forced to use the high beam far more than i would normally do in my car. even with the upgrade, the light is still weak. even to the point that i decided to buy after market leds to replace them. the 2016 had a complete redesign of the headlights and i wonder why. as for the infotament system. it is weak to say it nicely. the fact that my 2014 model can not get the same features that they introduced in the 2015 (speech to text) and 2016 (car play) is appalling. especially when they say the hardware is not there for the text to speech but there are 3rd vendors who can give it on the 2014 models. as for the rust proofing on this truck. it was cheaply done and the protective film is wearing off. i would take it to the dealership but i decided this spring i will have it professionally fixed with some rust proof paint and not the cheap wax that gm used.
The backseat headrests do not remain in the upright position. they slide down with the slightest contact from the person's head. the maintenance/service person at the dealership indicated that there has been numerous complaints from owners. he indicated that at this time it is a "no fix" problem. this is unacceptable and does not meet the national highway traffic boards regulations on headrest equipment. this is a real safety concern. the service department indicated that a latch needs to be installed to hold the headrest in place. if this is not corrected, people will at some point in time sustain serious injury. i feel like contacting 60 minutes with the problem and your response.
truck vibrated new with 8 miles when we first drove it home. pinpointed specific speeds and returned 9+ times to dealership over 7 months. tires (twice), shocks and rear end were all replaced but did not stop vibration. 5 months from purchase we were followed by a neighbor and they saw my truck "dog tracking" (traveling sideways down the road). dealer noted but would not follow at distance and speed required to witness the "dog tracking". dealer told me they were clueless and come get the truck. local auto repair shop followed me and said there is definitely a problem. front center of wheel to back center of wheel measures 1/2 inch less on driver side than passenger side but dealer says that is not a good measurement because their computer says everything is fine. this truck vibrates and "dog tracks" and dealership refuses to make proper offer and has given up on repair attempts. i am presently seeking help from a different dealer.
Vehicle has shudder, wobble and vibration when being driven at speeds 40-80. gmc has diagnosed as a tire issue but vehicle has been seen 14+ times and tires have all been road force balanced, numerous times. gmc refuses to diagnose further and has not identified the cause of the problem. vibration has affected other components. commonly reported problem affecting 2014 gmc sierra trucks based on internet search.
No accident has occurred yet as a result of the following deficiency. headlights on my 2014 gmc sierra 1500 slt are totally inadequate on high or low beam. the lighting distance is inadequate and is so directional that there is no side flair lighting for turning like you have with conventional headlights. this is a serious safety issue and needs to be addressed immediately by the nhtsa. i have had this vehicle for 1 1/2 years and the problem is ongoing since i bought it. the dealer has no solution.
