I was driving down the road at roughly 30 mph when my fuel tank dropped. The front fuel tank strap fell off and the bolt was gone. The fuel tank drug on the road, which prompted me to stop driving. There are scrapes on the front of the fuel tank and the strap was bent. This is a huge safety concern because had the fuel tank cracked or fell off completely this could have caused a fire. Had we been traveling at higher speeds, this could have been a very serious accident. The potential for gasoline or diesel to ignite was absolutely present. It could cause a fire or even an explosion, potentially injuring occupants and causing damage to the vehicle. I was travelling with my kids and mom, so the risk of injury to multiple people was present. The manufacturers only response so far is that it was not an open recall issue so it is not covered. No warning lights came on when this happened.
The 2023 Suburban started shuttering on idle and loosing power on drive due to a misfire in bank 4, the fuel injector was changed, but the problem persisted. And now the dealer says that I need to change all 8 injectors. 2900 job on a car with 54000 miles. Crazy.
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.
Wife is rn at a trauma hospital going to work in the morning on a busy highway. While in front of hospital truck started to indicate to hit starter button. Truck was already running! wife stopped at red light. Truck stopped running would not start. Stuck in middle of morning rush hour traffic had to have truck towed to dealership. At the dealership they indicated they found metal parts in the oil pan. They indicated a further look into the engine indicated it was beyond repair and had to be replaced. Truck only had 42k miles on it. They stated they had another one same situation in the shop as well and that it would take several weeks to repair. I have learned that this is a major problem with this make and model and engine. Engine quit with no warning in middle of major highway. Thank god not in an intersection or freeway.
The fitting on the fuel pressure regulator on the engine began to separate from the housing and started spraying fuel all over the firewall and the fuel ran down the firewall onto the exhaust pipes. No check engine light signaled. The only way I knew that it was spraying, was I started to smell raw fuel through the air conditioning vents. Luckily I was able to get it to a dealer before any fuel caught fire. The dealer repaired it but gm stuck me with half of the bill for the repair. I have pictures of the failed part if necessary. This is extremely dangerous to anyone that may not pay attention to car issues unless a check engine light comes on.
Car jerks with initial acceleration.
Def sensor has failed and required placement. Required three visits to the dealer to get them to address it (grayling, mi, white lake, mi and charlottesville va). Transmission throttle body failed and required replacement. Took 2 visits to get it addressed.
