  THERE IS A SHUTTERING IN THE TRANSMISSION AS THE VEHICLE ATTEMPTS TO CLIMB SLIGHT/STEEP GRADES AT SLOW TO MEDIUM SPEEDS. AROUND 1500 RPM THE VIBRATION IS SENT THROUGHOUT THE WHOLE VEHICLE. HAVING TO INCREASE ACCELERATION TO ALLOW THE TRUCK TO SHIFT PROPERLY TO OVERCOME THE LACK OF POWER HAS CREATED A DANGEROUS SITUATION WHILE NAVIGATING UP SNOWY/ICE HILLS. THE VEHICLE ALSO PERFORMS A LURCHING OR SUDDEN SPEEDING UP WHEN DOWNSHIFTING WHEN SLOWING TO COME TO A STOP. DEPENDING ON ROAD CONDITIONS THIS CREATES A DANGEROUS SITUATION WHEN APPROACHING ICY/SLIPPERY INTERSECTIONS.

  WHILE OPERATING VEHICLE ON HIGHWAY, I EXPERIENCE A SHAKE/SHUDDER WHEN AT SPEEDS OF 50 MPH AND HIGHER. VEHICLE WAS TAKEN TO DEALER STATED THAT THE TORQUE CONVERTER DID SHUDDER. DEALER CHANGED TRANSMISSION FLUID AND I WAS ADVISED TO DRIVE FOR 200 MILES TO SEE IF PROBLEM WAS CORRECTED. SHUDDER STILL REMAINS AND NOW THE VIBRATION IS CONSTANT AT 70 MPH. I CALLED DEALER AGAIN WHO SAID THAT IT WAS PROBABLY A TIRE BALANCE ISSUE. I ARGUED WITH THEM AND STATED I HAD NO SUCH ISSUE BEFORE FIRST BRINGING VEHICLE IN. DEALER IS SETTING UP APPOINTMENT FOR ME TO TAKE IN AGAIN. VIBRATIONS HAVE LITERALLY CAUSED MY 6 YR OLD DAUGHTER TO VOMIT ON 3 DIFFERENT OCCASIONS WHEN IN THE VEHICLE. SHE HAS ONLY BEEN IN VEHICLE 5 OR 6 TIMES. VEHICLE FEELS UNSAFE AT HIGHWAY SPEEDS. I HAVE READ MANY FORUMS ONLINE STATING THIS ISSUE IS ON MANY VEHICLES GM HAS MADE. I AM CURIOUS AS TO WHEN GM WILL BE MANDATED TO TAKE CORRECTIVE ACTION OR BUY THE VEHICLES BACK FROM THE OWNERS.

• 12/22/2017· EXTERIOR LIGHTING

  THE HEADLIGHTS ON MY NEW GMC SIERRA 2500HD DENALI ARE HORRIBLE AND UNSAFE FOR DRIVING AT NIGHT. THE 25 WATT RATING AND 2,000 LUMENS ON THE OEM HID BULBS DO NOT PROVIDE ADEQUATE, SAFE LIGHTING FOR OPERATING MY VEHICLE. I ALREADY HIT A DEER WITH MY BRAND NEW TRUCK BECAUSE I COULDN'T SEE IT WELL ENOUGH IN ADVANCE OF THE COLLISION. GMC SHOULD BE HELD ACCOUNTABLE FOR PUTTING SUCH A LOW POWER, POOR QUALITY AND UNSAFE HEADLIGHT IN THEIR $70,000 VEHICLES. I'M RENTING A HYUNDAI WHILE MY TRUCK IS BEING REPAIRED AND THE HEADLIGHTS ON THIS $30,000 FOREIGN CAR ARE 10XS BETTER THAN THE ONES ON MY TRUCK. WHY?

  FIRST AND MOST IMPORTANTLY MY BRAKES ARE MY MAIN ISSUE AND SAFETY PROBLEM. I NEARLY RAN INTO THE CAR IN FRONT OF ME AT A BUSY INTERSECTION. MY TRUCKS BRAKES LOSE PRESSURE AFTER THE FIRST INITIAL STOP COMING TO ANY TRAFFIC LIGHTS, STOP SIGN, SLOW TRAFFIC, PARKING LOTS ETC... NO MATTER HOW SLOW OR FAST THE TRUCKS MOVEMENT IS. FIRST BREAK ATTEMPT IS OK BUT 2ND STARTS LOSING PRESSURE AND 3RD ATTEMPT IS COMPLETE LOST OF PRESSURE ANF AND THE TRUCK JUST ROLLS UNTIL IT SLOWLY COMES TO A STOP. I WORRY ABOUT THE SAFETY OF MYSELF AND OTHERS MOTORIST REGARDING THIS ISSUE. MY SECOND COMPLAINT IS MY DRIVER SIDE MIRROR. EVERY TIME I GET INTO MY TRUCK AND START IT. MY DRIVER SIDE MIRROR MOVES OUT OF ITS SETTING AND I CONSTANTLY HAVE TO FIX IT.

• 12/11/2024· FUEL/PROPULSION SYSTEM

  The pigtails to the injectors are prone to failure. The vehicle without warning throws multiple codes and immediately limits power and speed while shaking. This can cause a dangerous driving situation. This is a known problem and is on many online forums as a common failure. The repair shop gets so many of these that they were able to diagnose the issue over the phone and noted that it usually happens around the 200k mile mark. However many reported this as an issue while under warranty. The issue is with the metal connector material being prone to failure and arcing.

In my situation I was driving at low speed went to stop and abs light came on from oil on my rotator, I also heard a knock from the rear wheel. I pulled over and looked under the truck to find my axel seal leaking fluid all over my tire and breaks. I looked into the Facebook form on this problem and found many people with the same issue. Had the truck towed to the dealer where the are refusing to repair and not coving under warranty for 1” bigger tires. My truck only has 39,000 miles and a axel seal should not be going out, and if so should be covered

• 11/28/2024· POWER TRAIN

  The vehicle had a shudder when I first bought it and towed a boat. Around 60-70 it felt like a tire out of balance. The truck is stock no alterations. New tires and the vehicle has the same shudder. Had the tires balanced three times at different tire shops with no correction. I was getting my oil changed and the shop suggested a transmission and transfer case oil change. Once they looked up my vehicle they told me I would have to go to a dealer for the transmission oil change. I brought my vehicle to a GM dealer for the transmission oil change. They diagnosed my vehicle with a bad transmission causing the shudder with the only fix a new transmission at $7,800. I have yet to replace my transmission. Reading only thousands of GM owners complaining about the transmission issues. Two other types of transmission have had recalls and fixes but this version no fix. GM knowingly has produced thousands of faulty transmissions not offering to correct. I have spoken with multiple transmissions shops and they all know the issues. GM should honor their faulty product either replacing or correcting it. It’s a shame. I didn’t realize what the issue was till it was past the warranty. Upsetting knowing it was messed up from the new sale.

  I was in an accident on October 20th 2022 while driving home. U had just reached the top of a sharp crest on a two way road. As I started to straighten out the wheels coming out of the turn I noticed my direction was still as if I was turning the wheel. I tried to brake and pressed the brake but it went to the floor and the truck kept going. I collided with the other vehicle and it was a miracle neither of us were seriously injured or killed. We had problem with the steering box about 2 years ago and had to have it towed to the dealership. The other vehicle was a Chevy 2500 with a custom steel flat bed & it slowed me down and I finally came to a stop with the front tires off the road. Neither vehicle alerted onstar & airbags did not deploy. His vehicle miraculously had minimal damage to the cab the majority of the damage was the metal gear box located under the bed in between the cab & tires. It was super scary & left both vehicles disabled.

  On July 5, 2024 while traveling and towing our 5th wheel (7,200lbs) with our 2017 GMC 2500 6.0L GAS engine (with the 6L90 transmission) and without any previous warnings or signals the check engine light illuminated and approximately 10 mins later the vehicle went into limp mode with "Transmission Hot.....Idle Engine" warning, causing us to lose power of the vehicle. We coasted over to the side of a 2 lane road with no shoulder and stopped the vehicle to let it cool down. This happened several times leaving us stranded in places that were NOT safe to allow the transmission to cool because we had no other choice since we were on country roads with no pullouts. At this point, we were just trying to get to the closest safest place to disconnect the trailer, so we could have the vehicle looked at by the GMC dealer. The closest place was an RV park approxiamately 20 miles away, so we limped there and disconnected from the trailer. Our safety and the safety of other drivers was a huge issue since there was nowhere we could pull over where we would be out of danger. We had no warning that our transmission was bad up until this point. The dealer inspected the vehicle and confirmed on July 8, 2024, that the vehicles transmission failed and needs to be replaced. We serviced our vehicle religiously and had the transmission flushed/changed at 49,944 miles. The failure of the this transmission occurred at approximately 54,000 miles. We were stuck and without our vehicle for 7 days while we waited for The GMC dealer to replace our transmission. There are plenty of problems with the GMC/Chevrolet 6L90 transmissions and unfortunately, we fell victim to this problem. GMC should be held accountable for issuing a recall as we could have easily caused an accident and serious damage to ourselves as well as others. This transmission is failing causing it to be is unsafe.

A week after the fire I received a 2nd recall in the mail for the same recall. Today is July 9th and my truck is still in the shop waiting on parts that have been on back order this whole time.
