This 2018 Jeep Grand Cherokee Trailhawk Diesel was purchased from Joe Vogel and Tim McGaha at Lake Keowee Jeep.
Professional, easy, and quick transaction- THANKS!
Bittersweet day trading in the JK that I had put a good bit of work and $$$$$ into but the new Jeep should fit our current needs a bit better.
Our new Grand Cherokee uses the VM Motori 3.0-liter V6 Diesel engine, More info HERE.
Dealer Ad is HERE (CarGurus), window sticker is HERE, build sheet is HERE.

First two pics below were taken at dealer, remaining pics were taken about a month later when the rain finally stopped. At this point we had transferred the old tag over, hard wired the V1, bought the WeatherTech Black Cargo Liner (P/N 40469) / Envelope Trunk Cargo Net / Genuine Jeep Accessories Portable Cargo Tote (P/N 82208566) for the back, installed the rock rails, installed the BOLT 5/8" Receiver Lock (P/N 7018448) and Jeep Hitch Receiver Plug (P/N 82208453AB), and had the entire front end (front bumper/hood/fenders) covered in Xpel Ultimate Plus Paint Protection Film (VIDEO) by Sun&Shield Automotive Films- AWESOME work. Note, this will make the flat black hood decal shiny, but we were OK with that.

SO the dealer sales dept was great but service did not top off the DEF (Diesel Exhaust Fluid) when they did the PDI.
I initially thought I would do what most do, buy the Peak BlueDEF sold by WalMart and other hardware stores and top off myself, but when I received it via FedEx the date was almost a year old. The fluid expiration date was less than 3 months away so that was GAME OVER, back to WalMart it went. The Peak BlueDEF might be OK if you check the date code prior as outlined HERE.
Peak BlueDEF: Flyer, Brochure, Safety Data Sheet.

You can also buy DEF at the pump where big trucks go to get Diesel, but some DEF pumps have a magnetic lockout. I sourced the Five Star DEF Magnevator 2 from Amazon to keep in the Jeep, now we can get the same cheap and fresh DEF trucks use even where the magnetic lockout is in play. That said, the local QuikTrip with DEF does not have magnetic lockout but better to be prepared.

Also, if you ever let the DEF fluid get low enough your Jeep will lock you out from starting the Jeep....not super safe but this is what the Eco Nazis have done for us. In case of low DEF AND starter lockout, you can follow these instructions courtesy of GDE and Davemd: LOW DEF EMERGENCY START

Valentine V1 radar detector installed beside rearview mirror and direct wired (hard-wired)- V1 Manual HERE.
Rearview mirror top plastic trim piece removed first, and then lower piece. Taps used in mirror plug to get -/+ for V1 adapter, short cord routed up/over to V1 and tucked in. Bottom plastic piece snapped on to mirror base and then upper piece snapped on to lower piece. 15 minutes and done, more details in pics below.
[EDIT] NEW V1 Gen2 replaced prior V1 (Owners Manual, Quick Start Guide, Programming Guide, Troubleshooting, How To Upgrade)


Mod#1- Mopar Rock Rails (P/N 82213525AD, old P/N 82212157AB with tube) sourced from Group1 Auto Parts.
I found they had these for the cheapest shipped price, a new-to-me wholesale online parts dealer AND they could get them. I had many canceled orders from dealers that couldn't get them or wanted $$$ to ship.
MANY dealers said they would not fit a 2018......but they come from the factory on 2018 models.....not sure why they did not include them with the skid plates that the Trailhawk comes with?

Good idea to check hardware that ships with rock rails on delivery, my bag had no holes and I was short ONE bolt and had to wait for the selling dealer to rectify, what a way to screw up a planned installation weekend because Mopar QA was out late partying and couldn't count to 24 when they packed my hardware.....McMaster Carr was my backup plan if the dealer didn't deliver but still a few days out on delivery and additional $$.
Mopar will refund me the cost of the bolts I had to order but we're almost at 1k miles and I am just now getting ready to install these after receiving the missing bolt. Group1 staff was great after I reported the missing bolt, but Mopar couldn't get it together.

Overall, the installation was not difficult but just required a bit of time. Having helpers is better than flying solo, we were able to get this done in about 6 hours spread out over 2 days with me doing most of the work- it can be done and it can be done on a 2018 Trailhawk

I assembled some pics and notes to supplement the factory instructions here:

BOLT 5/8" Receiver Lock (P/N 7018448) and Jeep Hitch Receiver Plug (P/N 82208453AB) installed. Bolt locks are coded to your key.

WeatherTech Black Cargo Liner (P/N 40469) installed.

GJ forum's antsjeep found that an ECU cover from a Durango fits our JGCs, P/N 68334597A. Sourced from Mopar Wholesale Parts, this piece easily clips to the ECU bracket for a cleaner looking engine compartment.

10k miles, time for oil/filter change and since I get two years for free under the Jeep Wave program (limited to 4 oil changes/tire rotations within 2 year time frame, summary HERE), off to Akins Jeep I go. Fuel and any residual water were drained from the fuel pump/filter assembly at 10K miles, and again at 20K miles when both fuel filters were changed (27mm or 1 1/16 socket, I used the 1 1/16 since it was a 6 point and less apt to round off the plastic hex nut on the filter).

After the Jeep Wave Program has been used up:
OE Mopar Oil Filter [P/N 68229402AA] and 8 qts/2 gals Shell Rotella T6 Full Synthetic Heavy Duty Engine Oil 5W-40 sourced from Amazon for oil/filter service every 10k miles.....also plan to install a NoSpillSystems drain valve (P/N 10-14150-01 (Standard Design Drain Valve and 1001 (Small Straight Drainer)).
(2) OE Mopar Fuel Filters/Water Separators [P/N 4726067AA] sourced from Amazon for fuel filter service/replacement every 20k miles.

(NOTE: ECOGARD X10232 Engine Oil Filter and ECOGARD XF10307 Diesel Fuel Filter are great value alternatives and offer their own warranty.)

The Shell website, technical data sheet, and data sheet all list API CJ4 on the specifications/approval list but not MS-10902. However, Shell Rotella T6 5w40 is the OE Mopar oil and can be seen on TSB 18-078-16 when FCA changed the oil spec in 2016 for the Jeep/Dodge EcoDiesel motors.

I found an EcoDiesel Oil/Filter change DIY video HERE, EcoDiesel Fuel Filter change video HERE.
Some helpful forum threads: Diesel Oil Change DIY - A Few Lessons Learned (disregard OLD oil spec in this writeup).

BEM-Auto OBD2 Port Lock (aka "Tune Saver", SKU: BTS-U1A) installed. Peace of mind that I will know when my ECU OBD2 port requires access at the dealer and we can discuss whether they really need to flash my ECU, some of the "improvements" they install make things worse.
The principal is that the lower piece that goes over the tab is not clamped tight until the bolt is tightened with a proprietary key, this is a much better solution than the other items that clamp into the plug itself and risk damage.....and MADE IN THE USA I asked that the unit they shipped me not include any verbiage/logos and they obliged, great customer service and very responsive to my email queries.
Installation and operating instructions HERE.


Block Heater Wiring Harness (P/N 68186526AB) purchased from Group1 Auto Parts.....block heater already installed in the block from the factory so all you need is the wiring harness.
Some helpful information/pics/diagrams can be found on WK2 Jeeps. Also JeepGarage Forum threads HERE and HERE, Jeep Forum thread HERE, YouTube Videos HERE and HERE.

Front windows and windshield top strip tinted by Mr. Tint. We have been going to Barry Wood for years and he never fails to impress, great work and reasonable price.

At around 30k miles, the OE Goodyear Wrangler AT Adventure with Kevlar (265/60R18) tires were almost at the treadwear/replacement indicators (at these indicators there is about ~2/32 tread remaining). We had been pretty satisfied with the Cooper tires we had on the old JK AND Cooper tires are still MADE IN the USA so I started looking to see what would work for the current WK2. Cooper now has three different Discoverer AT3 tires, video HERE.

Cooper Discoverer AT3 4S (265/65R18) were selected and with the larger than OE size, 65k mile warranty. I also replaced the spare with a Cooper Discoverer SRX (265/65R18) to match, the SRX was a little better styled/sized to fit in the spare tire well......I guess that is why the non-matching Kumho Solus 245/65R18 was selected as the spare for the OE tires. Per this forum post I reduced the air pressure in the spare to ~30PSI, still above the TPMS threshold. And although it might not seem like much, I did trim the noise dampening/felt from the base of the tire well to allow the tire to fit with the cover latched (tight but latched) and the plastic storage bins were removed to accomodate the larger spare too. Some additional forum discussion on full size spare tires HERE and HERE.
To correct the speedometer and odometer with larger diameter tires AlfaOBD and maybe a KAOdTECh security bypass will be required. KAOdTECh forum thread HERE, Generic RAM bypass harness installation instructions HERE- to see where the two CAN terminal blocks in the Jeep can be accessed this guide, although not specifically for the bypass, shows location/access points. There are some other security bypass methods and harnesses out there but the KAOdTECh seems to be the least complex to install. Chris Briggs assembled some excellent instructions HERE for the AlfaOBD process required to update tire circumference. I used a level and tape measure to measure the tire diameter on the Jeep and plugged that number into this calculator to derive the circumference (which was 780mm diameter=2451mm circumference). It is recommended that the bypass module only be installed when needed to use AlfaOBD and then removed to maintain security from hackers. More on AlfaOBD features can be found HERE and HERE.

Since Kauffman Tire sold out to a lesser brand, I had been driving all the way to Butler Tire. My son had an awesome experience at University Tire-Loganville so I thought I would try them. I submitted a quote request at 6:30AM and had a response back shortly after they opened, QUICK. Prices were competitive with TireRack so no need to haggle. They ordered the tires that morning and received/installed them that afternoon- Installation was perfect. Crystal Sands went above and beyond, University Tire really puts customer service first- THANKS Crystal and UT staff
