@JeepCares Would this qualify me for a loaner car?

It depends on the dealer. I've only had loaners when it was a warranty repair. Jeep might reimburse for a rental if the dealer won't provide one when they should.

Standard Warranty ends at 36k miles or 36 months from date of purchase, whichever comes first.

What’s work?
That’s a no fuel crank 💯% when fuel is injected rotation slows from higher compression values. Multiple conditions can cause that: air in inlet side to HP pump from fuel filter, restricted fuel filter, fuel transfer or gyro pump failure, fuel control valve failed mechanically open, short to ground in fuel control harness, dump valve mechanically failed open, internal failure of HP pump, face seal failure on HP lines from pump to rail or rail to injectors, open return poppet in injector and also a start inhibit for whatever reason that would disable all injector drivers.
Fuel transfer: high volume/low pressure
Injection pump: low volume/high pressure
If a leak is present on HP side it will start just takes an extended crank time due to pump being low volume.

You’re within the 36 months and 36,000 mile bumper to bumper warranty and really within the 10yr/100k powertrain too. Sounds like it’s Jeep’s problem.

Well they think its from a dirty air cleaner. Its been changed and we shall see if it fixes it. They also think that the taser is what is causing the jeep to not be able to start stop function.

The tazer has the start /stop function disabled. It remembers the last position the button was in and stays there. Push the button to use the function, it will stay there. Push the button to shut of the function, it stays there. It doesn't automatically go back to being functional after every restart.
