I believe the GM 13.4 infotainment system, particularly the navigation system and the radio control exhibit a very bad driver distraction that could lead to wrecks. Specifically with much more traffic now a vast majority of people traveling beyond places they are familiar with rely on the bigger screens on new vehicles so they get a clearer picture of turns ahead. I have experienced multiple occasions where the Silverado infotainment/navigation system randomly unpairs itself from my iPhone and then I’m forced to handhold a phone for navigation which is illegal in my state. I’ve talked to others that have the same problem, the screen going blank and it unpairs whether wireless Bluetooth or USB connected to the proper port. Unacceptable for a $70,000 vehicle. Also GM apparently in an attempt to advertise Sirius radio and subscription plans displays what appear to be warning signs on the display thereby distracting a driver again. The only way to change out of the Sirrus default stations reliably is to push a very small software button smaller than a pencil eraser. Again you must take your eyes off the road for a couple seconds to perfectly align your finger with the active portion of the software button. I see no way to say default to say radio on startup. You can on the steering wheel toggle many pushes to get through factory presets but many of those presets take you back to the menus to order sirrus radio. My background is electrical engineering and IT systems. I’ve never seen a more complicated and unreliable sequences and I don’t believe GM fully tested it. There is no doubt in my mind it’s a serious distraction more so than just about any other distraction because it’s particularly annoying and then puts the driver in a bad mood. I understand Android phones work slightly better but the population of Apple phones is significant. I’ve spoken with GM customer service several times and Apple several times GM blames Apple Apple blames GM and Google/Android head unit

Reduce Acceleration drive with care and engine light came on. Can’t go faster than 40 MPH and unable to reverse. Only 8,000 plus miles. According to mechanic, it’s a sticky transmission valve and there should be a recall.

Hi - I'm filing a complaint against Chevrolet with the NHTSA's Office of Defects Investigation. I purchased a brand new 2024 Chevrolet Silverado in Dec of 2024 from a dealership in MA. I've had the truck for only 2 months and only a couple thousand miles. I was in Quebec with my family for a ski vacation and we were driving back on [XXX} when my truck suddenly started making loud engine noises. I was able to get off the interstate to a gas station and then the truck turned off and would not start again. I had the truck towed to a Chevrolet dealership in Granby, Quebec. There was no warning or alerts before the engine failed. This is a known issue that the NHTSA is currently investigating, it has to do with the 6.2L V8 engine in GM vehicles from 2019-2024. The engine is seized and cannot be repaired, truck needs a new engine. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001. This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s recall remedy for Recall 25V-274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy. To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V-274, 473 of which involved an oil viscosity change and 26 a complete engine replacement. Additionally, ODI has received 191 reports of L87 engine failures in engines produced after the production period cited in Recall 25V-274. GM reported receiving 6,953 complaints of post-remedy engine failure. ODI is opening this Engineering Analysisto continue investigating complaints of post-remedy engine failure. ODI is expanding the scope of this Investigation to include engines produced after the production period cited in the recall.

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.

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.
