JLU Rubicon Issues

[cdgeorge79]

Ok, so I wasn’t going to unload here but I am looking for help/advice. I leased a 2018 JL Rubicon on May 22nd. I brought the Jeep back to the dealer on May 28th with 350 miles due to the following issues:
- driver seat coming unstitched
- Jeep died twice with a series of dash lights and dinging noises. One time it started right back up and the other time I had to push it off the road.
- paint defect on rear fender
- front metal bumper had a large scratch

I asked to have the paperwork cancelled and to return the Jeep. Too many issues for me to be dealing with on a $50,000 vehicle. I’m mostly concerned about the stalling and how they tell me they did a software update that supposedly fixed it. It’s been two weeks and I’ve been driving their loan car that they gave me on the 28th. It’s a new grand Cherokee that they took out of inventory that I’ve put 800 miles on. They were very nice to let me drive it. Anyway, I haven’t heard much of anything from the dealer even though I’ve left several messages for the GM to call me. Even the service advisor won’t return calls. I happened to drive by on Sunday and the Jeep is sitting in the same spot with nothing fixed. I called US Bank today and they don’t even have record of the account. So my question to you all is, what would you do?

The poor electronic unreliability and dying is the biggest issue . I would write down Everything , to document Everything , including their unresponsiveness and the length of time they have it without fixing anything , and tell Jeep it is a Lemon . Tell the bank to Not process any lease paperwork , since they have not done so . Better be prepared to play hardball . There are a number of threads on this Forum with similar experiences . It seems their common resolution is a buy back or an exchange , after FCA gets involved . They have the Jeep , so it is completely their responsibility .

Thanks- I’d love to have a Jeep, just not THAT one. So, a buyback or exchange would be okay with me. The problem is that I ordered this one and waited six weeks for it.

Check out the lemon laws for Texas , like how long it inoperative at dealer without being fixed , etc. Regardless if it was ordered and you waited , the dates start when you picked it up , and when you returned it to dealer as inoperable .

Check out the other threads , as I suggested . They are all the same , so you are not alone .

Also, check the fuses or get them to. There are a lot of reports of the fuses not being seated like they should be. I'd hazard a guess that they may be causing some of your problems.

Yep , just push them all in . (Don't take them out , however . )

I just bought a new JLUR, I checked my fuses because of I've read on this forum. a bunch were not in all the way. I just happened to cycle the gauge so I could see the voltage the first night out, it stayed what I think is low (12.6 to 12.7) even after a few hours driving, lights and other electrical load removed, made no difference. today I was noticing the voltage was now jumping around from 13.7 down to high 12's with no change in engine speed or electrical load. I tried turning on the lights, radio, A/C and it made no difference. I have a bad feeling I am going to experience electrical issues...

First time Jeep owner and already thinking I made a $50k mistake.

The same thing is happening to me. Any other info u can share?

 

[W1ck3d]

So you think you made a 50k mistake because of a battery charge gauge on the cluster?... That sounds a bit much

 

[WranglerMan]

@bikenutty and @DickZip the charging system on the Wranglers is different and I to was concerned when I saw the voltage jumping around but found out it’s normal, the alternator only charges the battery when necessary, normal resting voltage is 12.6-12.7 and the alternator will charge the battery when it’s needed.

Sometimes my voltage shows 13.5 or 12.7 while idle and other times it’s a pretty solid 12.7-12.8 and as I slow down in speed the voltage jumps up as high as 14.0 but once stopped it usually drops down to the 12+ range

Yes, it is normal behavior for a JL/JLU.

How did you find out about this, did you speak to a dealer, jeep is there a thread regarding this?
Thx

Here is a thread I started awhile back and it still kinda bugged me so I stopped at the dealer and talked to one of the techs and he to advised it’s normal, what I was told was the control logic of the onboard control module monitors the voltage and he believes there is some type of ECM either built into the alternator or control board
and as the battery needs charging the alternator then directs that voltage to the batteries and they both get charged so what I gathered was it’s some type of battery management as far as charging, I suppose it may make the batteries last longer if they are not constantly being charged

He also said that the it varies the most on deceleration so I can only assume that’s when it’s best to charge the battery if it’s needed but he did not know why it did that as he was still trying to grasp all the engineering design changes.

Life can be considered a comedy or a tragedy ; it's up to us . That said , document everything and start a paper file of letters to FCA and NHTSA IF anything Serious happens . So far , you are merely looking at numbers , and expressing an omen . The original OP , on the other hand , must act immediately to protect his investment .
