I was driving the vehicle and without warning it just stopped shut off and immediately shot an error code that there was a critical issue with the engine and that the oil pressure was low, and the vehicle would not start and was not drivable. It had to be towed to a dealership.

ENGINE, FUEL/PROPULSION SYSTEM
My 2023 Chevrolet Suburban with the 5.3L V8 engine has experienced lifter failure twice within less than [20,000 miles]. Both times the vehicle developed a misfire, engine belt like noise and was diagnosed by the Chevrolet dealership as having collapsed AFM/DFM lifters. All oil changes have been done at the dealership using GM-approved oil. The issue appears to be a known problem on 2021–2023 GM vehicles with the 5.3L L84 engine. GM has a technical service bulletin (PIP5776H) regarding lifter collapse, but no permanent fix has been provided. I am concerned this could lead to engine failure or stalling while driving, creating a safety hazard.

SERVICE BRAKES
I went to get in my 2023 suburban this morning to travel to the gym. It started but it would not shift out of park. I looked down and noticed the check engine light was on, the ABS light was on, and the park brake light was on with a lock and wrench. I had no issues since I purchased it used in March 2025 and yesterday it was driving fine.

ENGINE
The contact owns a 2023 Chevrolet Suburban. The contact stated that while driving at 10 MPH, there was an abnormal rumbling sound coming from the engine, with the check engine and traction control warning lights illuminated. Due to the failure, the contact restarted the vehicle and drove to an independent mechanic. The mechanic performed a diagnostic test on the vehicle and discovered a misfire in cylinder #3. The mechanic replaced the cylinder #3 ignition coil; however, the failure persisted. The contact then had another independent mechanic at the same shop inspect the vehicle, and the mechanic diagnosed the vehicle with engine failure. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was approximately 52,000.

UNKNOWN OR OTHER
When driving making a left or right hand turn my 2023 Suburban loose power and turns off and it is thrown in N and state to press start to restart my SUV. No codes are given to determine the issue. This has happen a handful of times. It has been taken into Chevy and they are unable to diagnose the problem. During the one visit they stated it was the battery and replace it and it has done it again. This is a very unsafe to drive the SUV as I'm afraid someone will rear end me and hurt me or someone else.

Transmission malfunction. This has appeared several times at highway speeds and low speeds. We have dad to limp along in the slow lane to exit ramp and take back roads to the nearest dealership. The current problem has been confirmed with error codes P0747. The dealership has scanned this vehicle and detected error codes in the past on two different occasions and found P176C in TCM on 08/01/23 and P17D6 on 10/24/24. Check engine light comes on with a screen prompt “Reduced Acceleration Drive with Care”. The transmission valve body has already been addressed once because of triggering limp mode.

ENGINE
What component or system failed or malfunctioned, and is it available for inspection upon request? - Initially, the vehicle began making loud 'clanking' sounds from the engine, which immediately affected the ability to drive the vehicle. Upon further inspection by a third-party mechanic, it was determined that the Crank Shaft had malfunctioned. This is a known recall for our vehicle type (model, year, engine), however, no recall notice has been received at this time. How was your safety or the safety of others put at risk? - The vehicle was slowing abruptly while in drive mode, potentially causing a vehicular accident. Has the problem been reproduced or confirmed by a dealer or independent service center? - Yes, we did not deliver the vehicle to a dealer, as no assistance was initially offered when we made an attempt to call and inquire. However, a third-party mechanic was able to determine the issue. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? - Not at this time, as the dealer we initially inquired with did not seem inclined to assist. We consulted with a third party. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? -No. Failure messages or icons came on after the engine failure began

ELECTRICAL SYSTEM
My vehicle suddenly stalled while driving. I later replaced the battery and discovered the telecom module was damaged, making the OnStar system inoperable. GM disagreed with my warranty claim and required me to replace the module at my own expense. I discovered the same issue is common in various GM models from 2023-2025. My Suburban and Yukon both have the same issue, making them defective. However, GM will not provide a free replacement under warranty.

Not sure the exact cause yet. But another big leak of coolant from the car. This is the 4th big problem with the same issue. I have been dealing with engine/radiator/coolant problems with this car since April 2024. It has been in the shop 2 separate times for 9 weeks total. With other visits in between. There is something wrong with this car.

This vehicle shifts hard and was identified to have a transmission valve issue. It should be under the same recall that other Chevrolet vehicles have with same issue. On top of this, Chevrolet cannot keep up with demand for this part making only 500 per week. I’ve been told it may be 2 months before I have my vehicle back.

Its been over a month and the dealership is unable to remedy this defect. I also called GM and they said the recall in incomplete and its in the preliminary stage. We are concerned that this is a serious safety recall and GM will not offer alternative solutions in a reasonable time.

Our Chevrolet suburban has 57,000 miles on it. We have started getting a check engine light and I’m getting code P1098 for the cooling control valve. This is a very common issue on these vehicles I’m noticing now. From what I’m reading in February of this year (2025) gm gave this issue an e code so these valves would no longer be covered pay the powertrain and they would now fall under emissions for a much shorter warranty coverage. This has been and ongoing issue since 2020. These valves are also commonly found to be on national back order causing long lead times and driving of the vehicles without properly functioning. GM knows these are and issue and shortening the warranty is not the fix. These vehicles weren’t bought with a short warranty and shouldn’t be able to be reduced to a short warranty.
