EXTERIOR LIGHTING
The sockets in the rear brake lights had excessive corrosion and was causing the terminals on the bulbs to deteriorate. The lights were malfunctioning in all situations from braking, turn indicator and running lights. I was notified by the system that there was a problem. After trying to resolve the problem and replacing the bulbs the condition only worsened. I was then pulled over by law enforcement that told me I had nearly no rear lights at night. After banging the plastic light frames I was able to make it home. I brought my truck into the dealer who inspected and found faulty wiring from what I was told. I them paid to have both rear harness change and all the bulbs replaced to repair the condition. After review of the repair the dealer made no additional precautions to ensure that this condition would not return by placing any type of waterproofing dielectric grease in the sockets or connectors. So was this faulty wiring or simply a known defect. The dealer had them in stock which was surprising since I figure they would need to be ordered.

SERVICE BRAKES
Driving on the highway going approximately 64mph and the traffic lane shifted over and everyone started to slow down and when I went to apply some brake . The pedal got very hard and became very hard to push down effecting my ability to brake properly. This almost caused me to get into an accident and I had to shoot over to the breakdown lane giving me enough time to slow down. My pedal became very hard to push down. This problem continued throughout my travel and service brake assist came on after the fact

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
My complaint is of the intelilink system in this vehicle. While driving the system would change screens, when turned off would turn itself back on. It would hang up on phone calls, would make all these beeping sounds and change stations on radio. It was very distracting and I feel dangerous in that especially at night as I said would not stay turned off so the beeping and changing of the screen that would make the large(8”) screen go from night mode to day mode and shine into your eyes. When navigating to somewhere system would show that you were in one place, when you were possibly 20 miles from where it would show you to be. Bad because it maybe showing and telling you turn by turn directions and all of a sudden it’s gone. This problem has been diagnosed by a dealer and repaired at a cost of $887.85. Was told that it is a very common repair that they do. Have contacted gm customer service and let them know that I thought a 2017 vehicle with 35000 miles should not have this problem and would like some kind of compensation for the problem and repair

ENGINE, POWER TRAIN
My vehicle recently started "shuttering" while driving. Service report says it is a "common GMC issue with the Torque Converter", $3200. They also reported a "substantial leak" in the radiator, and again, says it is a very common fault of GMC Trucks. And another $2700. If these conditions are as common as they indicate, why are there no corrective measures?

STEERING
As I was driving out of the parking lot my power steering suddenly was lost. A message appeared on the screen saying: Service Power Steering Drive with care and an esc message. A light also appeared. I was not able to steer at all and had to turn the truck off. I tried multiple times. After 5 minutes the message cleared as did the light. A day later (today- 4/19)the same thing happened in the parking lot. THIS IS VERY DANGEROUS. I have an appointment with the dealer. When looking up this problem it appears there are multiple recalls on other 2021 models but not the Sierra though I see many complaints about the same problem on the Sierra's. This is not safe and needs to be looked into further.

SERVICE BRAKES, FUEL/PROPULSION SYSTEM, STEERING
2014 Sierra 2500HD SN ([XXX]) Leaving on vacation towing camper with family Bosch CP4 fuel pump issue left me stranded on a HWY 9 just outside Clinton, AR which is a 2 lane HWY with no shoulder. The vehicle gave me no prior warning, dash board suddenly read power restricted followed immediately with complete power loss as I reached to top of hill. I was forced to steer and brake the truck and camper with no power, down the hill to prevent vehicles from passing at crest of hill. This left me and my family and numerous other drivers in a very dangerous situation as cars tried to pass. I had to open the hood and try to determine what was going on. I directed traffic until a Van Buren County, AR Sherriff’s Deputy arrived scolding me to get the truck and trailer out of the highway. I was forced to unhook trailer in middle of HWY and leave it. All the while, vehicles passing in danger of head on collision because there was only one officer directing both sides of traffic. GM is aware of this issue that cost me $10336 at GM Dealership where repaired. Had I been aware, I would have had this replaced this Bosch CP4 part to prevent the unsafe conditions I encountered. One message came on dash, restricted power, and I was powerless. Final Bill stated “Found Injection pump has come apart internally and has put metal through the system.” Internet search stated: According to InjectorsDirect.com, the 2011-2016 Duramax suffers from a high pressure fuel pump issue unique to this year-range model. Failure of this CP4 pump is usually catastrophic, causing metal particulates to contaminate the entire fuel system. Please help this from happening to another person. These trucks are advertised showing families pulling campers traveling through mountains. That is exactly what my family was doing. I have additional documentation if needed.
