Vehicle was taken to a shop and it has been determined that the passenger side lifters and rollers have sized due to the active fuel management system.

Original issue started at about 60K miles regarding hard shifts and clunking with acceleration with my 2017 Sierra 6 speed transmission. I had it inspected by the dealer when I purchased it, told it was normal for this model. Had it inspected by independent shops, told that this is a known issue, but not fixable without a new transmission. At 90K miles, began experiencing a whining sound while idling. Told it is in the torque converter/transmission housing but I could not afford the thousands of dollars for replacement/inspection. I had the transmission fluid serviced and changed as recommended with the dextran ATF that GM recommends in the manual both at 60K miles, and again at 100K miles as recommended. I also drive the vehicle reasonably, yet still at 130K miles had the transmission and converter fail. With no warning, no check engine lights or vehicle codes. Even after I lost 5th and 6th gear, there were no warnings or alert in my truck and despite the transmission giving out while on the highway. I feel this is a huge safety concern with both GM torque converter and transmission issues being known, as well as my vehicle not giving any warnings before, during, or after my transmission failing. I have had the warning lights checked as well, I’m told they are fully functioning when tested, so for some reason there seems to be an inherent issue with the truck’s warning system.

Diving my 2017 GMC SIERRA 1500 down the road and all of a sudden it had a big bang in motor,luckily only going 35 miles an hour. Had a slight tick in engine which I had gotten after most recent service visit, and had scheduled to take back to dealer. When I had checked it with a scanner, it only showed a P0700/P0711 code which was for transmission, otherwise no other lights or codes until that day when check engine light came on. Immediately stopped driving and pulled in parking lot and had car towed to dealer that day, [XXX]. They had called me back on [XXX], and said that they had to go further into engine for diagnosis, for extra charges. They called back next day and said that there was a camshaft failure that led to bent rod and metal in engine. Only fix was to replace engine. I then went and talked to them about cost and cause of failure, which is what I previously have stated. I then put in a call to GMC CUSTOMER CARE about the issue, and what they could do to help with issue, because no engine should fail with that few miles on it. Stated also that I had bought vehicle used with factory warranty still on it , and had all service since done at a GMC DEALERSHIP, and that they had all my records. And also, that the previous owner more than likely had all service done at a GMC dealership since it was all under warranty at the time. My service request with them is number [XXX]. My basis is on TSB Bulletin No: 20-NA-142 and Bulletin No: 15-06-01-002M . Which shows that GMC Corporation was aware of issues. At moment I am awaiting response from GMC.

On 12/5/24 took the truck to the dealership where we bought it with a complaint about the transmission. They took for a test drive could not find anything wrong with it, recommended we have the transmission flushed and filter replaced. They could not do the service so we got it into our local Chevrolet Dealership who did the work for us on 12/6/24. On [XXX] as we were departing a gas station in Tifton, GA, the transmission would not shift out of first gear and the temperature rose up to 234 degrees. Limped the vehicle to a campground, called a transmission shop who told us to bring in the truck at 7:30 am o 1/2/25. They were able to replace the transmission on 1/3. We had to drive it 500 miles before we could continue on our journey to Florida. Trying to accelerate on the Interstate and not being able to significantly put us at risk of a crash. Once the temp rose on the transmission the check engine light also came on. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On Friday, December 6, 2024, my “check engine light” illuminated on my 2017 GMC Sierra pickup. The engine is the gasoline version of the 5.3 liter. I took my truck to Brogden Buick/GMC in Olathe, KS. They informed me the trouble code was 219a, indicating there was a problem with the fuel/air ratio. On Monday, December 9, 2024, I was contacted and informed the fuel injectors needed to be replaced at a cost of approx. $2700. Based upon research I’ve conducted GM’s fuel injectors have been a service concern since approximately 2014. Service bulletin DCS5097 (N182198000-Special Coverage Engine Fuel Injector) was issued on July 26, 2019 that included my engine configuration. However, this particular bulletin does not appear to cover my Kansas based vehicle. I just had my vehicle at Brogden for a previous check engine light two weeks ago. This required replacing the fuel cell pressure sensor at just over $700. These repairs seem to be related. I’m reading that 2023 and 2024 Chevrolet and GMC trucks are also having fuel injector issues. This seems to be an ongoing problem that GM does not appear to be appropriately addressing. My truck is relatively low mileage with only 58,786 miles. It has never towed, is garage kept and is maintained in a pristine condition. I’ve never experienced fuel injector issues any any previously owned vehicle .
