Traveling on the interstate late at night in the winter with my family, which includes small children, a clicking noise began but then went away. No diagnostic lamps came on, everything seemed fine, vehicle responded appropriately. Moments later, on a remote stretch of interstate, we lost power and the engine shut down. The vehicle would not turn back on. We were stranded in the dark on a freezing night.

After getting gas just outside of Pueblo Colorado on [XXX] I was entering [XXX] and luckily I was in the right lane when all of a sudden no power to the vehicle. I was able to make it by inches in the clear on the shoulder of the road. Being [XXX], I had trouble crawling over the console through the passenger side of the vehicle because I could not safely see the traffic on the interstate to exit the vehicle on the driver side. The state police could not come to assist us with any type of traffic control because of other accidents. The BNSF railroad has a mutual aid pack with them when needed in an emergency situation. They were able to come assist us with the red lights for traffic control, and the tow truck arrived and was able to flatbed the vehicle to a GM Chevy dealership. The tow truck also delivered our 26 foot travel trailer to the nearby campground. If it wouldn’t have been for the BNSF police this could’ve been horrendous accident because of the traffic. I have never been in a more scary situation as with the 2023 Tahoe built by a major corporation and being as unsafe as it is. I have been told the engine needs to be replaced because the bearings failed with metal fragments found in the oil pan. GM has been aware of this problem with the 6.2 engine for many years and has never done anything. Is it gonna take people getting killed on the highway to get something done.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that soon after purchasing the vehicle, the vehicle's lane assist feature would be active with no other vehicles in the contact vehicle's vicinity. The contact also stated that multiple other electrical defects would occur such as the backup camera activating while in drive(D), the instrument panel intermittently going blank, and various other defects. The vehicle was taken to the dealer on multiple occasions where they failed to duplicate the failure. The contact then stated that while driving at 80 MPH, the instrument panel went blank. The contact attempted to pull the vehicle over; however, an unknown turn-off of the vehicle warning message appeared on the instrument panel as a warning chime was also emitted from the vehicle. The contact then stated that the vehicle then came to an abrupt stop where the engine and brakes seized, while traveling at 34 MPH. Due to the failure, the contact was taken to the hospital where they were treated for whiplash, inflammation in the neck and spine, 7 bulging discs in the spine, and pain in various parts of the body. The vehicle was towed to a dealer where it was diagnosed with engine failure; the vehicle's engine was replaced under warranty. Despite the repair, the contact refused to take possession of the vehicle as they did not feel safe driving the vehicle. The manufacturer was notified of the failure and a case was filed; the contact had yet to receive any assistance from the manufacturer. The failure mileage was approximately 15,000.

Onstar Telematics Module failure. Part is on backorder with no ETA. This module failure removes the navigation, Onstar services including safety notifications, clocks can stop working, Android auto/Apple Carplay services are not functional or intermittently working. My vehicle has stalled out at a red light. GM is refusing to cover the replacement saying it is out of the bumper to bumper to warranty but they have so many of these needing replaced they can't say when they will get the parts. Module has been confirmed dead by a mechanic at a private shop and by the dealership. GM states this is under the bumper to bumper to warranty even though it controls parts of the power train and should be covered under powertrain warranty as well.

I am writing to express my deep frustration with a recent issue I have encountered with my brand new 2023 Chevrolet Tahoe (VIN: [XXX] ). Following the expiration of my complimentary OnStar subscription, I discovered that all voice-activated and Bluetooth functions are inoperable unless I purchase a separate wireless plan at $25 / month which I cannot afford. This is a stark contrast to my previous six Chevrolets, all of which allowed hands-free phone calls and navigation functionalities via Bluetooth without requiring an additional subscription. I have contacted two Chevrolet dealerships, spoken with numerous employees, and reached out to OnStar, spending a total of nearly two hours on the phone attempting to resolve this issue. Unfortunately, no solution has been found. My primary concern is safety. Manually operating my phone while driving is unacceptable, and in some states illegal, putting myself and others at risk. Additionally, the lack of hands-free navigation significantly detracts from the convenience and value of the vehicle. While I appreciate the technological advancements in the 2023 Tahoe, the current system feels restrictive and potentially detrimental to customer safety. I understand the potential for additional revenue through data plans, but I believe the potential for unsafe driving and safety concerns outweighs this consideration.

I've had my 2023 Tahoe for 15 months, purchased Dec. 2023 Issue #1. Dash message on start up " Restraint System Needs Service". I noticed small lights overhead (buttons for tail gate, sun roof, reading lamps) were off. I pressed some of them, and dash message went away, and lights came on. Everything worked fine. I've narrowed it down to the passenger side reading light. When dash warning comes on, I press reading light, and whalla! all works fine. This has happened about 6 times over the last year. Issue #2. After driving many hours (9 hr drive, then a 2hr drive, then 4hr hr drive on different days/nights) in rain with wipers in auto mode, using defrost on and off as needed. Suddenly, wipers stop working as well as headlights in auto mode! Scary. Pulled over and waited with engine off. Restarted and still nothing. I was able to use headlights in full ON mode. I turned the wiper switch all the way from top-pulse to the full-on 4-6 times really quick back and forth, and like magic, everything worked again! This has happened 3 times in the last 2 months (always during several hours of rainy weather driving). Dealer says they can't fix what they can't witness. I suppose my only recourse is to video tape it and then show dealership.

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.

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.
