2020 Dodge Durango Engine

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.

When accelerating to pass another car in front of us on a 2 lane highway we experienced a loss of power and all instrumentation flashed on/off/on, then it posted a check engine light and stated that auto start stop wasn't working. Power came back and we finished the pass but it could have resulted in a head on collision.

When accelerating, the vehicle tends to lose all power and starts to decelerate and check engine lights comes on, also states the start stop function is disable. Really tough trying to drive on highways because of this happening quite often.

Leaking transmission oil cooler, due to clamp installation by factory. Known issue which dodge created service bulletin for but does not correct sending bill to consumer, for manufacturer defect
