I recently purchased my beautiful 2012 Saraha about a month ago.
Yesterday I ran my kid to school with no problems. About an hour later I started the Jeep but had difficulty as it had a very low unstable RPM idol of about 500 RPM which lasted a few seconds--then the engine died. I attempted to start it again...this time the starter would only crank, but no engine fire. After several attempts, I gave up and called Jeep.
Their recommendation was to start it in neutral and see how it went. I did and the same story happened (on a cold engine), but this time I think there was a faint smell of gas. The engine briefly cranked over and then quit.
By the time the tow truck arrived to tow the Jeep to the dealer the engine was fairly cold again. The tow truck driver attempted to start the engine. This time the engine turned over and continued running fine, however, we both smelled gas. Off to the dealer the Jeep went.
Today I received a call from Jeep. They cannot identify what is wrong at all. The engine starts fine, they smell no gas, diagnostics are fine....I asked them to keep the car and see if anything pops up, perhaps on cold start. Fortunately they agreed.
Could this be vapor lock? I have taken the Jeep off road twice, however, I haven't done any of the crazy stuff like my 19 year old son does! Any thoughts from anyone? The obvious thought was the fuel pump, but they are denying there is a problem.
I failed to say I only have 2800 miles on it!
