2007 with 185k. No engine problems. Burns some oil (about a quart per 3000). Replaced water pump at 170k.

 

54,000 and change here. The engine began chirping at startup in cold temperatures/winter, which I think is something I've seen others mention. Otherwise, no problems.

 

09 X. Coming up on 97k. Holding strong.

 

120k + and running strong

 

101k on my 08. It uses about 3/4 quart of oil per 1k miles, which bugs me, but it runs perfectly and I've had no issues. I did have a cat go bad somewhere around 70 or 80k. I'm not sure if it was oil burning, or not, that caused it. The mechanic that works on my other vehicles says he replaces LOTS of Chrysler cats and wasn't convinced that was it, so I don't know. It was under warranty.

Bottom line: My Jeep has been great and I enjoy it far more than any vehicle I've ever had, even my 93 YJ, which I dearly loved. I'm going to run this thing until it caves in on itself.

 

07 Sahara 4d

150,000

Replaced water pump at 110k.

10-30 GTX, uses anywhere from 3/4 to 2 qt between 4K mile changes and has since I bought it at 23k.

 

2010 with 88,000 miles on it
I am hard on the pig & have had zero problems. I do maintain it but it does see redline on a daily basis. Running regular 5W20 oil.

 

2007 Sahara cream puff here - only 53K original miles!

Was guzzling Mobil 1 10W30 so I switched to dino oil. Now uses a quart every 2500-3000 miles.
Intake manifold leak was stopped in December by 1/2 bottle of Bars Leaks Liquid Copper Block Seal.
Rear brakes replaced a while back too.

Does have a funky blend door on driver's side HVAC, but that's not drivetrain.

No other problems to report.

 

185,000 on my 2011, NO ISSUES.....did swap to 5w40 oil and made a huge difference....Lovin it still!

 

2010 with 50K. No significant issues. Just curious....what differences did you see after switching to 5w40?
