NHTSA Complaint #11615208 — 2019 DODGE GRAND CARAVAN

I had the check engine light on for an unknown amount of time, as the initially lookover of the vehicle with the dealership advised it was a gascap sensor. However, they did attempt to fix by changing the sparkplugs when it was inspected June 2024 which didn't correct the issue. Since then, it has been looked at by 2 mechanic shops due to the following problem. When I drive at 40+ mph, the car starts shaking violently. When ran with diagnostic/ testing the engine, it was found that Cylinder 2 keeps misfiring/ has a pressure issue, even after replacing the spark plugs and the fuel injector. Even after replacing those components, the cylinder misfire , lowered compression, and the shaking while driving all still persisted. They suggested fixing the issue with replacing the entire engine and avoiding driving until then, as driving it could potentially cause the engine to stop working while driving/ cause an accident. The dealership advised the engine issue would fall under the powertrain. It is available for review, as I have avoided driving it since, due to worries that the car will either stop working while I drive it, or the engine could result in an accident.
