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 flashi…”

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 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.

“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.”

“Automatic Emergency Braking system activated at ~77mph. Essentially I had started braking appropriately and at about the same time the AEB system seemed to conclude more breaking was needed.

Seat Belts 4 1 injury

“While driving a 2023 Chevrolet Suburban (VIN: [XXX] ), my [XXX] son was seated in the second-row center seat and was properly buckled in with the factory shoulder/lap belt. He turned around briefly to grab something from the back of the vehicle, and during that movement the seatbelt fully extended and then locked in the automatic locking mode.

“The drivers side, female end, of the seatbelt comes undone when cold. This is reproduced every single time it is cold for approximately 5 minutes of driving until the inside of the vehicle warms up. This happens with both primary divers of the vehicle. We took it to the dealership we bought it from but because there is not a current recall and they cannot reproduce the issue since our current temperature is in the 40s, they won’t replace it under warranty. No warning systems go on when this happens while driving.”
NHTSA complaint #11720994, 2026

“The vehicle was purchased brand new from the manufacturer. Because the third-row seating was rarely used, it was not immediately apparent that the car was delivered without one of the required seatbelts. Once the issue was discovered, it was promptly reported to the manufacturer. However, the customer service representative refused to address the problem, stating that the warranty period had expired. This is a serious safety hazard. A missing seatbelt poses a significant risk of severe injury or death in the event of an accident, and it requires immediate corrective action.”
