NHTSA Complaint #11639153 — 2021 CHEVROLET TAHOE

2021 Chevrolet Tahoe Engine began misfiring and check engine light and ESC warning indicators displayed as I was driving. I pulled over and shut off vehicle, read manual and restarted engine. Same problems occurred, so I drove to Chevrolet dealer which was a mile away. The advisors said I shouldn’t drive it on the expressway or any further since engine had known problems that GM was aware of and it would blow up. Scans showed P0300 & P0305 for Cylinder 5 misfire. Major Repair included replacement of all lifters and push rods on both banks and the camshaft taking 17 days. This engine should have a GM Recall due to its severity. I was told the engine usually blows up before the warranty period is over and GM would just fix it. Unfortunately for me, my engine failed after full warranty and while I was traveling out of state to a family wedding, costly me directly. GM did pay half of the cost of repair which indicates admitting fault. The major safety concern is when an engine blows up and the driver cannot control the vehicle causing accidents or fire (and being stranded). There were No previous indications or symptoms of engine failure prior to date the problem occurred. Police departments in Illinois have had the same problem with this engine and their entire Tahoe fleet needed a new / repaired engine. This is an unacceptable action by GM to just wait for the problem to occur instead of proactively recalling the engine for repair.
