I brought my Chevrolet Suburban High Country in to the dealer pursuant to a recall for engine issues due to a manufacturing defect in connecting rods and crankshafts that can cause catastrophic engine failure. The service center changed the oil viscosity and fill cap and stated that the change should eliminate the issue. I have had persistent engine knocking upon acceleration since then and it is getting louder and more prominent. A suspension warning intermittently flashes as well. Please advise, thank you

We purchased a 2023 Chevy Suburban in January of 2026. In May the vehicle shut off on me at a stop light. The check engine light flashed after I was able to restart it. I took it to the dealer and they said they "couldn't recreate the issue" even though there was an engine misfire code on all cylinders. They told me to come pick it up and bring it back if I had further issues. The second time this happened I had issues getting the vehicle started. This was June 2026 Once I finally got it started and was driving all the service lights started going off and the check engine light started flashing. I took it to a different chevy dealer and was told the same thing. This time I had 23 different service codes that showed up. Including the engine misfire code. So we picked it up and continued to drive it. On July 10th we were towing a 7k lb camper home when we lost all power. Thankfully we weren't driving fast and we're able to stop. This left us stranded at a busy intersection for 2 hours. The car would not go out of neutral. Had we been going 70 on an interstate we could have very seriously been hurt. The car had to be towed back to the dealership where we were told the engine locked up and needed to be replaced. My husband and I had our [XXX] child in the backseat with us. This was a family car that we purchased and told twice that they couldn't find anything wrong with it. The vehicle has been at the dealership waiting on a motor since July 11th.

The fuel pump module on this vechicle failed, and there's a recall for 2021 I believe other years should be considered as well since this was a known issue as soon as we arrived at the dealership and they wanted over $400 to replace this part which is only $45.

The sunroof drains continue to fail. I’ve had multiple occasions where the car has had drains back up or be disconnected.. This is a safety issue because it creates mold as water falls in the headliner and then the cabin. It also creates rust, particularly behind the dashboard. That’s not rust proof. Despite being under warranty, the dealers are useless and helping address the issue because it’s la design flaw. The multiple water intrusions also affect the electronics in the vehicle., potentially disabling critical features like airbags and safety systems.

The engine of this car has been under recall for multiple issues during the time we have owned it. The most recent issue that was experienced was total engine failure and electrical malfunction while driving on a busy street near train tracks. The vehicle was making a loud banging sound moments before this occurred. I wasn't even given time to get to a safe spot to investigate the issue. When it shut down, a quick message flashed across the dash board--stating ability to shift had been lost (or something to that effect)--the vehicle then flipped into neutral and immediately lost power. My safety was put at great risk due to the fact that the entire vehicle shut down moments after I crossed over a very busy railway track. The vehicle had to be towed to a nearby Chevrolet dealership where it has been confirmed there was total engine failure as well as blown main electrical fuse.

My 2023 Chevrolet Suburban Premier is covered under GM recall 25V-274 for the 6.2L L87 engine defect (loss of propulsion from connecting rod and crankshaft failure). In XXX, the dealer notified me my vehicle required a full engine replacement under this recall. Wareing Sheridan Chevrolet in [XXX] replaced the engine, and the vehicle was out of service approximately 12 to 14 days. Approximately 6,000 miles later, on XXX, the replacement engine failed while I was driving on the interstate highway near Billings, Montana. There were no warning indicators of any kind until I suddenly lost power. Only at the moment power was lost did the check engine light come on and a low oil pressure warning appear. I was barely able to get the vehicle off the interstate before it died. I had my family in the vehicle, and losing power on the interstate with no warning created a serious risk of a crash. The vehicle had to be towed to Denny Menholt Chevrolet in Billings, MT. On June 13, 2026, the dealer confirmed the vehicle needs a second complete engine replacement under the same recall. This is the second L87 engine failure and second full engine replacement on this vehicle under recall 25V-274. No crash or injuries occurred. I have an open case with GM (#XXX).

While driving on interstate XXX on 4/17/2026 my vehicle lost power I had to pull over on the shoulder thankfully I was able to do so. Restarted the vehicle for just a short bit and it said loss of engine oil pressure and died. would not restart. Ultimately had to be towed to a GM dealership Lynch Chevrolet in [XXX] . Was told the engine was shot and was covered under the safety recall. There was a recall on the motor I had brought it in to get rectified sept 2025.a heavier weight oil was added and filler cap replaced with 40 weight oil identification. . I just had an oil change the day before the incident on 4/16. What is concerning I'm worried about the long wait plus plus online blogs that indicate the engine failed numerous times even after replacement. I was told from the dealership that the engine was on back order and they cannot give me a time on when it's going to be available. But again I'm worried about this vehicle in general in moving forward or trying to anyway. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle mileage is approximately 45,000 miles. While driving in the rain the front windshield wipers stopped moving and were stuck in the down position. They would not activated with auto, manual, or wash commands. Rear wiper still functioned. This happened while driving down the interstate which resulted in having to slow my speed in heavy traffic and go out of driver position to see through a clear spot in the windshield, took exit 1 mile later and tried to find gas station, approximately 1 mile after exiting the wipers started to work again. This also happened at approximately 35,000 miles on the vehicle and the wipers did not work for multiple days, even with vehicle turned off for 12 hr period. Took to dealership and by that time they were working again and the dealership could not find anything wrong. Both instances happened on weekends so could not take directly to dealership while issue was present.

Regarding a catastrophic engine failure involving my 2023 Chevrolet Suburban equipped with the 6.2L L87 engine. There is an active GM service bulletin that we never received from either Crabtree or GM. Vehicle details: • Purchased in North Carolina in 2024 • Approximately 4,000 miles at purchase (used, still under factory warranty) • Currently at approximately 60,000 miles • Within the 5yr/60k powertrain warranty at the time of failure Incident details: On Friday 2/20, the engine experienced a confirmed catastrophic failure while my wife was driving on the interstate at highway speed. The vehicle abruptly lost power, creating a significant safety hazard. She was able to maneuver to safety, but the situation presented a serious risk of injury. GM has since towed the vehicle and confirmed catastrophic engine failure. We have been provided a rental vehicle - not a comparable one either (they refuse to address that also). Given the safety exposure and warranty status, I am evaluating potential potential claims including breach of warranty, implied warranty of merchantability, and any product liability considerations. I am also interested in understanding leverage for buyback, diminished value, risk of serious injury to my wife, or extended warranty resolution. I have preserved documentation, service records, and a written account of the incident.
