Transmission has had shifting, shudder and failure to go into gear from day 1 of owning the truck. Has been to the dealer on several occassions for the same issue just to be told that they either could not reproduce the issue or it was normal. On another occasion the dealer was able to notice some shudder and shifting issue and replaced the valve body under warranty. Now that the vehicle is out of warranty I’m being told the vehicle needs a complete transmission rebuild and torque converter at an out of pocket cost to me of $8500. I know of many others with the same issues from the onset of owning these vehicles.

Subject: Potential Issue Related to Recall N202314870 for GMC Sierra 1500 Problem Description: I own a 2019 GMC Sierra AT4 (VIN# [XXX] ) and have identified a potential issue related to the drive shaft. Although my VIN does not appear in the official system as affected by recall N202314870, the vehicle exhibits the following symptoms: 1. Unusual and consistent vibrations in the drivetrain while the vehicle is in motion. 2. Noises coming from both the front and rear differentials. 3. Concern regarding the integrity of the drive shaft, as these issues align with the details described in the recall. Given that this issue potentially affects the safety of the vehicle, I kindly request a review to determine if my unit should be included in recall N202314870 or any other related campaign.

Issue 1: Driver side front seat airbag connector separated disabling the airbag. (repaired at my cost) Issue 2: Transmission (10 speed auto) developed stutter and skip consistent with complaints resulting in recall of 2020 (next model year truck) due to risk of rear wheel lock up. GM needs to include the 2019 models that were built as 2019 (as 2020) in one of the plants while they continued to build the 2018 as 2018 "classics" during the changeover. My cost to repair will be $3600 and there is not guarantee that the new valve body is any better or if GM is simply giving me another 46k miles to wait for another failure.

My end of year 2019 produced GMC Sierra 1500 5.3 V8, 4WD X31 4 door truck had a serious malfunction that could have caused great harm. I was driving down my driveway at approximately 20 mph when the truck's rear wheels locked up, stopping the truck instantly, sending me into the steering wheel narrowly missing the windshield with my face. After a moment, I attempted to drive again to move the truck out of the travel path. When I did, the truck back wheels completely locked up again (when I reached 6mph). I had the truck towed to my local shop and was told that it was the transmission locking up making the wheels lock up. The part (transmission) that was ordered for repair was on national backorder and took over two months to get my truck repaired and functional again. I was fortunate to have a warranty (now expired) and pay a percentage of the repair fee, however, the total repair fee was near 12,000. This was paid for by myself and my warranty company. Considering the part was on national backorder, I know that these types of problems are occurring with many of these trucks. I learned of the recall for this same problem that my truck had and checked the recall for my vin. To my complete surprise, my truck was not listed as being recalled, even though the EXACT same problem occurred with my truck. I would like to get the cost of the repairs refunded considering it took GM so long to recall the problem leaving me to pay for their errors. This is not a cheap automobile and was expected to be built well. I am very fortunate that I was not on a major highway or traveling at a high rate of speed when this happened. It was a very scary ordeal being propelled into the windshield of your vehicle when driving due to abrupt, extremely unusual 100% mechanical failure of no fault of your own. This recall should be expanded to include ALL vehicles that have the faulty transmission, including mine. Repair receipts can be provided. I appreciate your time and consideration.

Opened Oct 23, 2025 · No close date supplied

Status: open (inferred from source dates) · Engine; Engine And Engine Cooling:engine:hard Parts Internal/mechanical

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001).  GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274.  This presents a potential safety risk that warrants further investigation.  ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274.  This presents a potential safety risk that warrants further investigation.  ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.

PE25001 · Loss Of Motive Power Due To Engine Failure

Opened Jan 16, 2025 · Closed Oct 23, 2025

Status: closed (inferred from source dates) · Engine; Engine And Engine Cooling:engine:hard Parts Internal/mechanical

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024.  GM cited the root cause as a supplier manufacturing and quality issues. GM’s  recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure. To date, ODI has received 1,157 allegations of engine bearing failure. GM submitted 55,464 reports in total, with 29,752 unique VINs. ODI continues to receive allegations of L87 engine failures which fall outside of the scope of recall 25V-274. Based on GM’s recall, ODI will close this PE. NHTSA will continue to investigate complaints of engine failure outside the scope of recall 25V-274 as part ofEngineering Analysis (EA25007).
