[QUOTE="Danarch, post: 449992, member: 21093"] First, welcome to the Jeep family. Jeeps can certainly have their issues. From the picture looks like you have the JK as opposed to the newer JL model (nothing against JL’s). I think being a 2018 I think you are fairly safe with the “kinks” being worked out. I know the 2012-2014ish when they switched to the 3.6L there were some issues I believe with the heads and cams. I think every model has its issues, especially in the first few years of a model production. While in my opinion the Jeep is an amazing vehicle and capable of a lot of things. I think the Jeep has an imagine of the go anywhere do anything you want by some, but then at the same time people don‘t maintain them or push them beyond their limits, they modify them at whim with lift kits, spacers, lights, tires etc. not knowing the full effects of their “upgrades”. For instance putting 35”, 37” tires on a dana 30 axle and then pushing the jeep to its limit off road is asking for trouble. Installing a 3“ or 4” lift then not taking the time to install adjustable control arms, change out the driveshafts etc. is asking for trouble. We have four JK’s in the family, one mine and one my wife’s which we have the capability of monitoring some of the systems live. The temp on the JK in my opinion runs hot. Each of them get up to 226 on regular basis and then the fan kicks on and it come back down. To me i’d be more comfortable around 212 but seems to be common. Second it seems common for the oil filter housing to leak (fail), from my understanding this is from over tightening the filter cover and causing the plastic housing to crack. When you replace any electrical components / sensors make sure to use OEM as somehow the “jeep” knows they are not OEM and the new part only seems to temporarily fix the issue or not fix it at all. I am not sure how the jeep knows, but it does. At 35,000 miles you should be fairly safe, but I usually change all the fluids when I buy a used Jeep. I bought a 2015 HR JKU with only 15K miles and have had all the fluids changed except for the coolant and brake at this point. There is always a risk with a used car and one reason we have did purchase extended warranties with each of them. I assume you crawled underneath and to see if it looked like it had been abused or not. 10-15 minutes underneath a Jeep can tell a lot about it. Enjoy and have fun exploring. [/QUOTE]
