Hi guys please i need help i went i have a 2009 Jeep Liberty i cant even enjoy cause of this problem, So everytime i drive for a good amount about 10-20 minutes and once i shut the car off and go to get out get gas or school the store market ANYWHERE come back it does not start back up until 10-15 minutes it cools down i guess. i went to jeep spent almost 800$ they told me it was needed a tune up, update the computer software, change spark plugs so there i am spending money i need for school. i drove home from Jeep Mopar happy its all fixed once i go to get gas come back same problem went back next day they said they cant figure out the problem cause theres no engine light so they took my money for no reason and very rude. Today i went to a local mechanic he said its the crank sensor and ofcourse i fell for it again paid 180$ and same problem less than an hour Please im begging help me guys find the problem. just a student trying to get to school and work this sucks. I posted a video please watch see what i mean. i cant be waiting 10-15 minutes in the cold to start back up.
