NHTSA Complaint #11704575 — 2020 DODGE DURANGO

Under heavy load or high RPM the engine starts shaking badly and the engine loses power and is very unresponsive to throttle. After 30 seconds of light use the problem goes away but comes back immediately upon heavy load or high rpms. There is a technical service bulletin about this, TSB: 09-011-25. The computer indicates a severe misfire on cylinder #1. I first took the Durango to my mechanic since it is out of warranty. The replaced the coil on cylinder #1 and all spark plugs, but the problem continued since the issue is a manufacturer's defect inside the engine. When this occurred the engine light came on the dashboard but nothing prior to the shaking, only after the shaking started.
