Have 2 questions for everyone. Have a 2013 wrangler 2 door. Engine light keeps coming in seams to be the oil pressure switch. Wanna find it to see if something is loose or other issue. Second have a rattle in the passengers rear end, good clunking when going over bumpy areas. Dealerahip said the tightned the sway bar but still there. Suggestions on what to look at?

 

Re the rattle, is your stock jack secure?

Re the engine light, when is the light coming on? Cold starts, or just randomly? And are you getting a code?
There's a self-test you can do, the instructions to read some basic codes is in your manual.

If I recall, there have been reports of the two-stage oil pump being stuck in low on some pentastars.

 

I had an oil pressure sensor act up on my 2013 Rubi. Dealer replaced it under warranty and was done in an hour and a half. No more CEL.

I just found and fixed an annoying rattle and squeak that was driving me crazy. Turned out to be the left rear console screw had backed out. I checked all of them and the seat mounts while I was there. Squeak and rattle both gone. Sounds almost like new again for 36k miles
