Well, the dealer provided me w/ a diagnosis (sort of) today.
They did not provide me with the list of codes, but I will ask for them.
They claim these 11 issues need to be addressed:
1- Diagnostic for CEL: 5V sensor shorts when hot.
They literally don't know WHICH sensor, so their recommendation is:
"Need to swap out sensors one at a time from a known good Jeep to eliminate possible causes of short. Vehicle has 6+ sensors that can cause this issue along w/ wiring harness & PCM."
Cost of #1: $1,350 - POSSIBLE, but how much could it possibly cost to simply replace all of the suspect sensors instead of diagnosing them one-by one through substitution? BTW, I replaced the crankshaft position sensor in October. It was a Duralast sensor (lifetime warranty), and it resolved the code and rough idle, but it could have failed.
2- Cabin air filter: HORSE SHIT. I replaced it less than 1 year ago and I won't pay the dealer to do this.
Cost of #2: $79.95 - DENIED
3- Engine Air Filter: HORSE SHIT. Also replaced less than 1 year ago and I won't pay the dealer to do this.
Cost of #3: $99.95 - DENIED
4- Brake Flush: Meh... It has a lot of miles and it has probably never been flushed.
Cost of #4: $279.95 - POSSIBLE, but definitely over-priced at the dealership, ESPECIALLY if done in conjunction w/ #5 & #6.
BTW, I wouldn't do this UNLESS I was also doing pads & rotors at the same time.
5- Brake job (front): Pads found to be at or under 3mm. Recommend replacing or resurfacing the rotors.
Cost of #5: $639.95 - DENIED (Not a service to have done at the dealership)
6- Brake Job (rear): Pads found to be at or under 3mm. Recommend replacing or resurfacing the rotors.
Cost of #6: $660.70 - DENIED (Not a service to have done at the dealership)
7- Complete Fuel System Service:
"Appears overdue". HTF can they say a service like this "APPEARS OVERDUE"... what can they
SEE?
Cost of #7: $370 - DENIED; What does this even entail (besides a new fuel filter) unless they are replacing failed parts?
8- Right Rear Axle Seal:
"Leaking and requires replacement and reseal to resolve concern."
Cost of #8: $865.86 - Wait for it...
9- Differential Flush (front):
"Appears overdue"
Cost of #9: $269.95 - I expected this expense this year, but my local oil change place can do it for about half.
10- Differential Flush (rear):
"Appears overdue"
Cost of #10: $269.95 - See #8. I didn't see any leaks, but if it is leaking, why is this not MUCH cheaper IF done while repairing the axle seal? If the axle seal isn't really leaking, my local oil change place can do this for about half.
11- Transfer Case Service:
"Appears overdue"
Cost of #11: $209.95 - I expected this expense this year, but my local oil change place can do it for about half.
In short, I don't see us having anything other than possibly #1 done at the dealership, but I feel like this is
WAY too much $$ to swap out parts until they find the problem.
Any insight or criticism of the above is appreciated.
