Consumer Description

Started having misfire issues. Replaced spark plugs. problem continued. started having to add antifreeze regurlarly. 1 quart per 300 miles. multiple P0302 error codes. Dealer 1st tried to tell me was a loose coil pack. looked at it again and said needs a new head gasket possibly a whole new engine. 117,000 miles and this seems rediculous for a 60,000 dollar vehecle. Especially since Jeep already issued an extended 150,000 mile warranty for 2011-2013. with 100's of these same issues still happening on 2018's and latter they clearly did not correct the defect.
