Noticed a/c getting warm. Attempted refilling Freon without success. Took by auto shop and they discovered the welds to the top driver side of the condenser were in question and ruptured causing a Freon leak. They advised a replacement and stated “this is very common with GM model trucks and SUVs. Save your info and report for recall. They need to recall these models for their a/c issues.” Condenser replaced with receipt attached

STEERING, SERVICE BRAKES, ENGINE
My vehicle has on two separate occasions experienced a failure where the steering locks up, the engine shuts down, and the dash displays warnings about stabilitrac and trailer wiring. The vehicle has had random electrical glitches for some time, but they have escalated to a safety issue. In doing research, my issues sound very similar to those issues which resulted in a recall to earlier vehicles of the same generation, on report 17V-414. Googling the issue also points to insufficient grounding at the battery and / or the G218 grounding connection.

POWER TRAIN
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.

8 speed transmission shudder reported by GMC for my model. My truck has 35,500 miles and has the shudder posted in a technical service bulletin by GM. The supposed fix is x 20 quart fluid flush, new filter, and flash the computer. GM will not cover under any warranty as they say this is a “fluid change” even though the manual says this fluid should not be changed until 72,000 miles. The dealerships act like they are just hearing about this which is a total lie. They were told over a year ago if they had any new on lot to change the transmission fluid to mobile one synthetic before selling them. This should be a recall as GM knew this was an issue during manufacture. This is a $1200 repair that should be covered by GM.

ENGINE, POWER TRAIN
#1 While merging onto the highway, the vehicle began to shake violently and have a sudden lose of power due to a misfire on cylinder 6 and 4. I was unable to merge onto the highway as the vehicle would not accelerate almost causing me to be hit from behind. I was able to get the vehicle off to the shoulder to avoid an accident as it was barely able to stay running and the CEL was flashing. The failed parts (AFM lifters/push rods and VLOM) have been removed from the engine and saved for review. #2 My family's safety was put at risk as the vehicle had a sudden lose of acceleration while trying to merge on the highway almost causing us to be hit from behind. #3 I spoke with my local GMC dealer and explained the situation and diagnosis that I have completed on the vehicle. That wanted me to pay out of pocket to tow the vehicle in and would not cover anything as the vehicle is barley out of powertrain warranty (72695 miles). I have been an engineer in the automotive industry for almost 10 years and can properly diagnose a vehicle and the issue it has. Trouble codes were provided along with pictures and videos as evidence. I understand when something is a safety issue and needs to be addressed as this is a common issue with GM 5.3l and 6.2l engines. I then spoke to GM corporate (Mandy, case# 9-12424996557) and once again they wanted me to pay for everything out of pocket even though this is clearly a safety concern with their product and the diagnosis had already been completed. This vehicle has all the maintenance records since it rolled off the showroom floor, proving that the failure is not related to neglect or poor maintenance of the vehicle. There is very clearly a design issue or manufacturing issue on this components. #4 Components are available for inspection by mfg. #5 There were not warning lights or any other indicators prior to the failure. Oil pressure was at 40PSI and engine temp was ~200F. All within the normal operating windows of the vehicle.

ELECTRICAL SYSTEM
In January 2024, I parked my truck in my garage and shortly after I smelled an electrical burning smell in our house. When I opened the garage, it had smoke throughout the garage and a very strong odor of electrical burning smell. I moved my vehicle outside and tried to find the source, but it was too strong to narrow it down, and the garage smelled like burnt electrical for days. I took the truck to a service shop and they could not find anything wrong at the time. Today, May 2024, I was having trouble getting my trailer lights working. Upon further inspection, I discovered the 7-way interface wiring harness on my vehicle had electrically shorted out and melted a hole in the plastic housing and left melted plastic on the truck frame. The tag on the wiring harness states TAG #138359 7-WAY INTERFACE HARNESS W/O 134971. I believe this electrical short/fire should be part of the NHSTA Recall 18E-014. That recall states those are aftermarket harnesses, but the harness on the vehicle in this complaint is original to the vehicle and was installed by the manufacturer. I plan to take the vehicle back to the dealer to have the harness replaced, but I am expecting pushback since the NHSTA recall states this is only aftermarket harnesses.

VEHICLE SPEED CONTROL, POWER TRAIN, ENGINE
The vehicle would shudder when trying to accelerate. I almost was hit by a semi truck trying to merge onto the freeway. Made an appointment with the mechanic then a couple days later I was at a stop sign and the vehicle would not accelerate at all. I placed in park the tried shifting back into drive and still nothing. I had to turn the vehicle on and off twice before I was able to shift it in drive an it actully would accelerate. Even then it would shudder and not accelerate fully. Very dangerous. Just hit 100k miles. GMC Certified Mechanic said the transmission is shot and needs to be replaced. Cost to replace over $6,000.00 Bought the truck in 2020 for $35,500 and just paid it off.

Experienced hard shifting in my transmission a couple before it all of the sudden it made a thing noise and didn’t want to move forward to easy. Babied it home and by then it was whining and whistling all the time. I Quit driving it immediately and had it towed. Being only a 2017 I can’t believe this happened. Plus I had a 2014 prior to this and I had the same issue but traded it off before it went all the way out. After going to social media I am finding out that so many people with mid to late model 2000s have had this same issue, even family. Plus I was told by 2 different transmission places this is very common in these with Chevy and GMC model trucks. How could this be going on? I am assuming because people don’t know to report. Being on disability and a fixed income this took a hit to my bank account, actually a home equity loan.
