2012 Grand Cherokee, V6, about 64k miles. Just had inspection at dealer 2 months ago. No problems until today.
Check engine light came on this morning.
Drive on highway about 15 miles at around 65mph no issues.
Local street, was going up hill and went to accelerate to pass and make a lane change..... sudden complete loss of acceleration and vehicle started slowing down. Tried again and could not accelerate. It made no loud noises or anything else odd.
Arrived where I was going (around the corner), parked vehicle for about an hour. Went out and drove again.
Engine light still on, but works fine. Drove several miles including up hill and accelerated no problem. Try variety of situations, like starting accelerating mid hill, accelerating from various speeds.... no problem.
Is it possible this was just a random one time misfire? Or cylinder going bad? I filled up with gas last night, maybe got a bad batch?
I am also about to deploy overseas in about 4 weeks so not much time to work with.
