  1. Check light came on

    Newbie Check-In
    The light in the picture below came on last night. I’m not very savvy with mechanical work but I read to check the gas cap and caps under the hood and I think those all up and it’s still on. Any ideas on things I can try before taking to mechanic? I also read could be low gas mileage and I...

    I bought this jeep today and I got it for a great price. It has 156,000 miles on it but I had a Jeep in high school and I know that if you take care of them, Jeeps will go forever. My question is what makes both the check engine and four-wheel-drive warning lights simultaneously light up? Both...

    I was driving up a mountain highway yesterday morning and my check engine light came on. I have made sure my gas cap is tight, done the 3x Acc to Run with the key, and it still won't turn off. It's not flashing, it just stays on. No new sounds or odd performance issues. Help? 7100 miles, no...
