a couple days so far and the light has not reappeared with the new fuel injector - hopefully solved. they mentioned potential reason may have been the amount of time the vehicle has been sitting........they purchased it jan 2011, and did not sell to me until a few weeks ago.

Engine Light

Just bought our 2008 Patriot about 3 weeks ago - 89000 K. Engine light came on on Monday and hasn't gone off since. Will try the gas cap thing, but we don't get a gas cap message. From what I have been reading - it must be a MS computer - reboot it enough times and it should go away :).

Spirit, try getting the code pulled if you can. Most autoparts stores can do this for free. Re-seating the gas cap is usually the best thing to try first, but it may take a few key on-run-off cycles to turn the light off. You might also want to wipe the filler neck off and the O-ring inside the threaded portion of the cap to insure a good seal.

....at seemingly random times, most noticeably at changes of seasons and weather. Gas cap, bad gas, excessive temp changes, all seem to trigger it. As long as it doesn't blink at me I tune it out.

Thanks, Hubby tightened the gas cap, even though he said it wasn't loose and it finally went off yesterday (about 1.5 weeks after it first came on). Has anyone ever used one of those code reader devices that you can purchase? I live in Canada and I don't know if/which auto stores may read them for free.

You can buy one for $80 or less. I got mine at Advance Auto on sale for $50. IMO on today's vehiucles having a scan tool is a must. Dealers charge upwards of a full hour just to pull a code( takes 5 seconds ). Many times being able to read the code and know what is wrong means you can fix it easily yourself. It also gives you some advance knowledge of what is wrong so the dealer/indy shop can't try and pull a fast one.

we were getting the mil after we had a tune up at dealership. they forgot to put oil filler cap back on. so took it back to check. they then said it was o2 sensors (lucky warrenty we bought covered this). mil off as they cleared it and back on in 50 miles. said cathaletic convertor below standard and needs replaced.

i didn't accept that as my research showed it could be "large vacuum leak". bought new gas cap and it was the problem (took 2 as first one wasn't tight). it takes a little force to now turn cap to remove. no codes in 2k miles

Check engine light

I've had my 2017 patriot for a little over a year; has about 22k miles on it. Drove to work like always, pulled into my parking spot, and the check engine light came one. I turned it off, checked the gas cap (it was tight), turned it back on- light is still there. Any ideas?

Hello jeshort6,

You've got some great advice here. If you decide you'd like to get this checked out by your Jeep dealer, let us know. We can certainly escalate to a Case Specialist once an appointment has been confirmed.
