I have a 2018 JLSU and had no problems, until the other day, 11,500 miles. Driving 70, 8th gr, the engine light started flashing and the motor shook with loss of power. No where to stop, I backed off and the light quit flashing but stayed on, along with the auto/stop light. I'm able to drive it but the power is way off and rough idle at times.I have gotten the impression the new 3.6l is right out of gc, so not new at all? this true, and if it is is there any bad issuessor reliablity probs with gc 3.6l?
I called the dealer and was told a 2 week wait; really?
I checked everything I could, had the code read (P105C) and have to wait to get it into the shop. Discouraging.
