I preordered my 4xe (my 3rd wrangler) and was so excited to pick it up this past Saturday (4/24). We drove it home - about 150 miles - and got up the next day to find a pink fluid on our garage floor. We took it to a friend who also drives a Jeep, and he told us to take it in as it looked like transmission fluid. So my husband took off work Monday (4/26) to drive back to Houston for repairs. The dealership got to it quickly but didn’t have parts in stock, so he had to leave with a rental. It’s now Wednesday, and after calling several times, we were told they couldn’t find the part, and they will update us when there is new information. We’ve now had the car in the shop longer than we’ve had it in our possession.

(Also, we were reading about 14.5-16 mpg... which seems a bit off but possibly unrelated.)

I know people say you’re buying problems when you buy a jeep, but this is a bit ridiculous. I’m very frustrated and upset, but we have no idea what to do but wait on them. Does anyone have any advice, or have you heard of similar problems with a vehicle straight off the lot?

Unfortunately buying the first wave of a brand new model that's very different than what wrangler has had before you run the risk of early adopter issues, and given current production issues worldwide most people are running into longer-than-expected times to get parts that are normally more readily available.

You should reach out to @JeepCares on here and see if they can offer any guidance!

It absolutely sucks to have a brand new vehicle experience issues right off the lot. Jeep says they have tested it 1.4 million miles prior to release but any first year vehicle is going to have some issues. A first ever hybrid from Jeep may have more growing pains than usual. This coupled with shutdowns, part shortages, a crazy hot buyer's market, etc. is giving me bad vibes about ordering one. I always tell people to buy the 2nd year model of anything new but I really like the concept and am willing to take a chance (though I will be leasing it to hedge my bet).

In any case, I hope your issue is minor and that you are back on the road soon. Jeep can make solid products - my v8 Grand has 158k on the odo and has never had an issue, just normal maintenance . It still runs like a scalded ape. I've had older Cherokees go 200k without issue. Of course, they are simpler vehicles but the heritage is still there. You may be the victim of a freak issue or something more widespread with the model. Only time will tell. Keep us posted.

After picking up my factory ordered 2020 JLUR from the dealership, I noticed a coolant leak the day after I got it home. I ended up having to take it back three separate times before they finally found and fixed the issue.

I was also very disappointed to have a brand new vehicle with such a glaring problem, on top of other things. But since the initial issues were resolved, I haven't had any more problems.

Hi @WreckEm711,

Parts issues are a nightmare for all car manufacturers.. We had to wait 2 months to get an issue fixed on our Honda late last year.

I would just pressure the service folks for a date when you will get the part. It is good your in a rental because that is costing Jeep everyday you don't have your vehicle back.

I am super happy to have my 4xe, but it being a new vehicle this is the first time I sprung for the 8 year extended warranty. Peace of mind in the future.

14.5-16 mpg seems way off to me, unless you were going uphill into a strong headwind. The worst I've seen in hybrid mode is 21 MPG with 23 to 24 being typical.

Did you have e-save with battery recharge on?

We were driving in hybrid mode. We were in the low 14s, but we got in some stop-and-go traffic. It only got to above 16 after we got off the freeway and onto the less crowded highway.

Did they accidentally give you a 392? That is just so way off. When I was doing 70+ MPH, the worst I saw was 21/22. Speed really kills the hybrid MPG in this vehicle but that's more than understandable.

Keep us posted, this is interesting.

Update: We contacted our dealership Tuesday they still have no ETA on parts. We do have a jeep cares ticket number, so we will see if that helps.

What is the part that failed? I've noticed the battery cooling pump and possibly the charging system wiring harness coming up a few times.

These issues seem to happen right away. So it could be a good sign for everyone that made it home from the dealer.

I've been beating on mine out of some caution as I have a road trip in June.

Unfortunately this is a very common thing that almost all manufacturers experience when they start producing plug in vehicles. If the pink fluid is coolant then the most common cause of the leak is overflow expansion due to an improper fill at the factory. Very easy to do considering how complicated the cooling systems are with these types of vehicles.

The next most common issue is a leaking connection or pipe. There are a couple dozen connections and plumbing everywhere....especially this vehicle. Jeep put the battery inside the cabin and the electronics under the cab between the frame rails and then one motor in the transmission and the other motor on the engine itself. All this stuff needs some cooling so there is plumbing all over the place.

So, the bad news is the parts are not common and are specific to the 4xe. The good news is most all those connections are very low pressure so they should last a very long time and not need service for 100k miles or longer.

I hope you get your Jeep back soon.
