   The dealer and Corporate Partner are refusing to perform the federally mandated Z46 safety recall (NHTSA 22V406) on my 2014 Jeep Grand Cherokee until they replace the supply line for a $1000, because they said it rotted/rusted. This factory supply line is made of nylon plastic and cannot rust. I suggest it blew out as part of a failing HPFP covered under the recall, and they misdiagnosed it. Furthermore, the technician and service advisor stated that they had not checked for…

   My 2014 Jeep Grand Cherokee suddenly developed a no-start condition after previously operating normally. The vehicle would crank but would not start. The battery and fuel injectors were checked and replaced as needed, but the problem persisted.

This defect has been the subject of previous safety recalls because it can cause engine stalling or a…
