Software Updates

Question for those more knowledgeable than me:

Are the various software updates "required" on the 2014 Turbodiesel JGC's performed no cost to the owner if you are under the 36k mile warranty?

I have put a ton of miles, 46,000, on mine in the first year of ownership and of course I had my first check engine light at 36,500 miles. A PCM update ($90) and a Transmission Control Module update ($162) were performed.

My second check engine light appeared at 40,000 mi for incorrect DEF. The injector was cleaned from excessive crystallization and there was no charge.

My third check engine light came on yesterday (46,000 mi) and I got another incorrect DEF message. The dealer put it right in and it turned out there was no problem with the DEF. Four updates were "required" (1) another PCM update (2) BCM update (What is this?), (3) HVAC update and (4) the DEF wiring harness zip tie doo dad.

Since I was already out of warranty when the first update was done I've been paying for these. Are those who've had the updates done during your initial warranty period having to pay for them? Are the charges I'm paying for actually just the dealership technician and computer time and the updates are "free".

Some enlightenment would be appreciated.

Re: Software Updates

They are free during the warranty. I don't know whether they are comp'd without deductible in the extended service contracts, but perhaps someone else can tell us.

I cleared my own MIL for the DEF system when it cropped up at 8k miles rather than taking it to the dealer. You might consider getting a ScanGauge or, if you're more technically inclined, a Bluetooth OBDII adapter plus a smartphone app like Torque Pro. With the specific codes, you can Google for possible root causes and decide whether you want to bother with going to to the dealer.

Some of those updates (like HVAC) really aren't required unless you are upset with how the automatic temperature control works (for example). I suggest monitoring the TSBs for your vehicle to see what has come down the pipe. God knows I am trying to avoid some of the later transmission updates, because it sounds like it may make it worse.

Conversely, I had the patch for the horrible oil life algorithm, the original HVAC patch to fix the horrible heater, and the end-of-August patch to fix the transmission. I definitely needed those; unfortunately, you can't pick and choose which TCM/BCM/PCM patches/fixes you get. They will just install the latest firmware version for whichever module and you get everything that entails: the fixes (or hacks, as the case may be) plus the new bugs.

Bottom line with Jeep firmware updates: if you aren't experiencing a perceptible issue, don't do it. Doubly so if they are charging you for the privilege. I have started bringing TSB printouts with me to the dealer to explain what I want to have patched.

Re: Software Updates

Treeguy,

If your CEL'S are emissions related, they "should" be warrantied beyond the 3/36 period...at least the major components. I wonder if your dealer is charging both Chrysler and you?

Re: Software Updates

A TCM update should be covered under the 100K power train warranty, I'd think.
