2024 GMC SIERRA 1500

ENGINE AND ENGINE COOLING:ENGINE:HARD PARTS INTERNAL/MECHANICAL

General Motors LLC (GM) is recalling certain 2021-2024 Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, and Tahoe, GMC Sierra 1500, Yukon, and Yukon XL vehicles equipped with a 6.2L V8 gas engine. The connecting rod and/or crankshaft engine components may have manufacturing d

The engine lost power on the Hwy. Resulted in having to tow the vehicle to the dealership for an engine replacement. The truck is a 2024 with only 20K miles. There were no alerts within the interior to make me aware there was a problem. The engineer starting make a knocking sound at the time of failure. I had just gotten off the interstate when it failed. I spoke to a representative at the dealership and they informed me that the same engine will be installed, with a new oil type. I'm writing this given this will diminish the value of the truck, and I have to be worried about the engine failure happening again. Next time it could happen on the interstate with loss of power. I can't trust that to happen.

1) In May of 2025 I attempted to have the dealership complete the recall which the GM app told me to schedule. Related to the L87 engine failure. According to their own document my engine manufacture date was to be replaced a defective. The dealer told me that there was "no resolution for the issue and turned me away. (see attachments) 2) In June GM changed the procedure adding the PICO test. (see attachment) 3) In October I received the official recall notice and scheduled the test. At the prior service visit I had the dealer give me back the old oil filter. I took it apart and found metal fillings in it. I reported this to the dealer. The truck had the PICO test and passed. They told me that "the filter did its job and the metal in it was normal wear and tear". They replaced the oil cap and filled it with thicker oil. I was sent on my way, told to call if I had any issues. 4) On 2-6-25 while driving 65 MPH on the highway, the engine just shut off without warning. The dash di

I get alert saying low oil pressure and the truck turned it's self off and won't start back up. And I got car's and 18 wheelers coming up from behind. They're not paying attention to my emergency lights flashing. It did this twice on me, first time in my neighborhood and the second time on major road with a lot of traffic. I call GMC Corporate office and they know about the Recall on the 2024 GMC Sierra engine cutting off. I was told I need to get a picture or video of the dashboard say low oil pressure and video with me trying to start it back up. I guess I'll have to get hit or kill for them to replace the engine. I have no documentation because I have no picture or video. Didn't know I was supposed to take a picture or video.

My truck started knocking and while driving home and it died on me in the middle of a busy street and would not start. I waved down a police officer and he kept me safe from cars hitting from behind.Come to find out it was the bearing rod and now I’m getting my engine replaced. My truck is a 2024 gmc sierra with 9,000 miles on it.

On 5 Feb 2026 I was starting my 4-hour drive back home. 15 minutes into my drive my truck lost power, several lights and the engine light came on. Truck was sputtering and making harsh engine noises and shut off on me. I was forced to exit Loop 2 (a major highway). Once I was able to restate the truck I went straight to the dealership. This truck had the recall done 15 Oct 2025. However, this issues still occurred. The motor gave out. Truck is 83K in mileage. well under 100K. Cost estimate is $6.5K. The technician informed me that a lifter collapsed in cylinder 5. This is clearly still part of the GMC recall issue for the 6.2L engines. What is my next step in this process. If I knew there was a major issue with these Trucks, I probably would not have purchased it. All maintenance has been done with same dealership to keep all service records excess able.

Post recall L87 I had a catasrophic engine failure. 70 mph highway engine seized lost propulsion. 38000 miles. No warning, Engine has been replaced by GM

While driving the vehicle I hit a bump on the road and all 4 windows in the vehicle went down. I did not push any buttons. I tried to close the windows and they would not close. Nothing happened when I attempted to close them. It was 10 degrees out I pulled over, and tried again with out success. I shut the car off, opened the door and closed it and restarted the car after a few minutes. I was able to close 3 of the 4 windows. I started driving and eventually I was able to close the last window. ON my drive I late hit another bump and again all 4 windows opened with out any action by me, I was on a highway, I again pulled over and was not able to close the windows. After I continued driving I was able to close 3 of the 4 windows and eventually the 4th. This is a safety issue.

Front grill cap blew off while driving.

Seat is squeaking loudly like if its loose or something is loose with it dealership and gm dont want to fix it they expect me to pay to fix something that ahouldnt even be happening on a 2 year old vehicle specially when you pay more than 70,000 dollars for a vehicle to be having this issue

While traveling 60 mph on a divided highway went to pass another vehicle. Had no throttle response the engine had completely turned off, locked up seized up. I’m not sure what caused the engine to just lose all power. Had to go back to the lane and luckily there was a turnoff where I was able to turn off the highway.

I was driving on the highway (using cruise control) when the front bumper grill started vibrating (so I tried to slow down) but it kept flapping and flew off before I was able to pull over. I then pulled over on the shoulder and had to walk back to retrieve it. My safety was put at risk because it could have hit my windshield and caused me to have an accident, or, it could have hit someone or another vehicle. I have it and it is available for inspection. It has not been inspected by anyone yet. There were no warning signals prior to the failure.
