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 job. 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 DEF Magnevator 2 from Five Star DEF 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.
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 couln'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 I decided to go ahead and change the fuel filters as well.
OE Mopar Oil Filter [P/N 68229402AA], (2) OE Mopar Fuel Filters/Water Separators [P/N 4726067AA], and 8 qts/2 gals Shell Rotella T6 Full Synthetic Heavy Duty Engine Oil 5W-40 sourced from Amazon.
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.
