6.2L L87 V8, connecting rod / crankshaft bearing failure even after I passed the recall inspection at a dealership. On [XXX], I was traveling approximately 55Mph and my engine completely shut off as well as the entire vehicle electronics. I lost power steering capabilities, and my brakes felt like they were kicking back at me. I was at crash risk from loss of power in traffic along with the loss of steering abilities, but I was lucky and was able to avoid traffic and get into the shoulder from 2 lanes away and slow to a stop. I got lucky because the loss of power steering made control extremely difficult. On [XXX], I brought my vehicle to All American Chevrolet in Middletown NJ for the safety recall N25249003 with 16,219 miles on my Tahoe. A few hours later I was called and said my engine was fine and passed inspection. On the day of failure, my car only had 21,111 miles on it. So, my engine still failed even after the oil change, and inspection process and it was extremely dangerous, after only 4,892 miles after their safety inspection.

What 2023 Chevrolet Tahoe owners say
Most recent owner complaints, unedited.
I own a 2023 Chevrolet Tahoe equipped with the 6.2L V8 engine. The vehicle has experienced repeated significant engine problems, including a previous complete engine replacement and subsequent issues with the replacement engine. The original engine required replacement due to engine-related problems. Following that replacement, the vehicle developed lifter noise and required another extended stay at the dealership for repairs. The vehicle has now been out of service for approximately 4–5 weeks while the dealership attempts to diagnose and repair the issue. After the dealership completed work to address the lifter noise, the technician identified an additional concerning engine noise. The dealership has since reported suspected bottom-end damage in the crankshaft area and has escalated the findings to GM engineering for further diagnosis and repair recommendations. I am concerned about the recurring internal engine failures, particularly given that this is the second engine installed in the vehicle. These problems raise serious concerns about the reliability and safety of the 6.2L engine. A failure involving the crankshaft, connecting rods, or internal engine bearings could potentially result in sudden engine failure or loss of power while driving. The vehicle has been inspected by an authorized GM dealership, and the current suspected damage has been reported to GM engineering. The final diagnosis and recommended repair are still pending. I am requesting that the federal safety agency review these repeated engine failures, including failures involving replacement engines, and investigate whether there is an ongoing safety or manufacturing defect affecting these vehicles.
The car had the recall done for the engine issues 1 year ago. Pico test past and oil was changed to new oil. All service is handled by Chevrolet dealer. Now the issue. After leaving home and driving on a highway for about 25 minutes I received lights on the dashboard indicating. Several issues. Flashing engine light, ecm issue amoung some others. I then noticed what sounded like a missfire of the engine. Since I was on my way out of town I decided to turn around and take directly to dealer. I dropped the car off. When I finally turned the car off at the dealer lot and restarted it I also noticed metal clanging coming from engine. The next day I was texted by the dealer that I would be getting a new engine. Car has 78,644 miles.
At 60,720 on car miles engine failed. This is the second engine failure. Dealership perfomred test per recall on second engine, and engine failed less than 30,000 miles later. Experienced loss of power for a few minutes before failure. The replacement engine had 52,000 miles on it.
The AFM/DOD system failed and resulted in lifters and rocker arm failure.
On 4/23/25, the check engine light came on and the vehicle reduced power. It was taken to dealership and a warranty service was performed, L87 Engine loss of propulsion. The vehicle was in service for 90 days. On 7/15/26, vehicle shifted itself into neutral while driving on the highway, with 4 kids in the car. This is a safety issue for our family and all around us, as car loses ability to drive at interstate speeds. It would not go back into drive, needed to pull over and get towed to dealership. Dealership diagnosed it needed a new engine and radiator; it was in service for 60 days. On 10/10/26, vehicle shifted itself into neutral while driving with one kid in car while driving on the highway. Vehicle gave the "conditions not correct for shift" and would not go back into drive. Vehicle was shut off and was stalled on the highway, after a time of it being off, vehicle started back up and the check engine light was on. This is a safety issue for our family and all around us, as car loses ability to drive, once again, at interstate speeds.
First occurrence was 2/03/24 check engine light came on felt stumble in engine continued driving to get home set up appt with dealership. They codes P318C and P318F were present numerous things were checked and found excessive crank shaft end play, removed oil pan and found thrust bearing in bottom of pan broken into pieces. GM authorized engine replacement. The vehicle had 4,603 miles on it. Repairs were completed and vehicle picked up 03/12/24 Second occurrence was 05/28/26 while driving at interstate speeds heard squeaking noise then knocking sounds coming from engine was able to make it home and had vehicle towed to dealership the next day. This time no codes but was determined to be defective engine and was replaced again mileage on vehicle this time was 33,521 miles I started using the 0w/40 oil as soon as recall came out actually before I received information in mail I am hearing rods rattling at start up now until oil pressure picks up on the latest engine installed but it still is running at present time.
I was picking my Tahoe up after a replacement on the blown motor was complete. (L87) I started it and immediately knew something was wrong. I reported it to the service advisor and the response was there were no warning lights so it must be fine. I asked them to sit in my car and they agreed it was not running right. They took it back and replaced a sparkplug that was causing the #2 cylinder to misfire. Almost 3 months later I was driving on the freeway when my Tahoe felt like it was going to stall. Again I had no warning lights appear. The diagnostics showed the same #2 cylinder misfiring caused by another sparkplug issue. This is all within 2,500 miles on a brand new engine.
While traveling on I-684 at highway speed, my 2023 Chevrolet Tahoe with 43,000 miles suddenly shut off without warning and automatically shifted into neutral. I had a complete loss of propulsion. As a car guy who has been following the GM 6.2L engine recall issue, I suspected it could be that. I was traveling in the left lane and had to carefully coast across active lanes of traffic to reach the shoulder. My wife and two young children were in the vehicle, and the sudden loss of propulsion created a significant risk of collision. There were no warning illuminations, messages, or other symptoms that I observed prior to the failure. The vehicle was subsequently towed to my Chevrolet dealer for diagnosis and is available for inspection upon request. As confirmed by the dealer, the engine completely seized causing the loss of propulsion. I will also share, about 1 year ago after the GM recall was issued, I took my truck back to the dealer. They cleared the engine for the propulsion issue, changed the oil for 0W40 and changed the oil fill cap in line with GM recall standards.
* Lifter bores and camshaft. yes * The vehicle started to shake and started sending out alerts for multiple problems while we were driving on the interstate * Yes. Bale Chevrolet estimated approx. $10,000 repair bill * No. It's currently at the dealership * As the car began to shake we started receiving numerous warnings, but not prior to the shaking.
