Rough running

I need help bad I bought a used 2007 limited 53000 miles. It starts and runs on like 5 cylinders and the lightning bolt lights up and its in limp mode. shut the truck off start it up again it runs fine but the light is still lite on the dash. Dealer blamed the detailer power washing the motor now 4 trips later sensors and a computer replaced it still doing it. Lemon law lawyer said to call the BB !! I'm hoping somebody had the same problem and can help THANKS

Change lawyers. Ur lawyer that specializes in lemon laws said to write the Better Business bureau??? Makes no sense at all.
Talk to ur service mgr about possibly exercising ur lemon law rights. Be nice, and u will be amazed how much they will help. They did me.
As for ur issue. Try drying each individual fuse in the fuse panel in the engine compartment first. Then i would check all plugs/leads. What code is it throwing?Good luck.

My understanding is that the lemon law applies to class A titles (first owner).. That may just be in PA but I wouldn't think a used vehicle would be protected as you don't know how it was cared for prior to purchasing it

Yeah, you have to be careful of wires.. I had a coolant temp sensor throwing errors on my tj .. Replaced it- same thing.. Stared at it a bit and realized the wire harness came out of the bracket on the firewall and was laying on the manifold.. The additional heat on the wires was causing my issue. Put the wires back on the firewall and it was fixed.

Yeah the trucks is stock looking it's in great shape and the Carfax didn't show any previous issues that all. Hopefully this is the fix and I'll be good to go.

Jeep is running on Battery. That's why you're getting Lightning bolt. The only time I get that symbol is when I turn key to the on position.

I never power wash an engine. Never. Ever. Ever. NO No No . Don't do it. BAd Bad Bad. Not even the engine compartment. No No No
What I will do is take a Acid Brush and clean it then hit with air.
I'll bet most problems on this forum are Car Power Wash related.
I'm curious as to how you got it off the Cuban Car Lot with this problem.

I'm an electronics tech. Keep looking. And get a bright light. If you can disconnect the connectors and blow dry with compressed air. Disconnect battery First. And then the connectors in the engine compartment. Do them. The last time I washed a engine with a water hose was 18 years ago. And I got water on a connector and had problems. But I got the water out. Lucky me.

I think Chrysler needs to send out a warning to everyone. A lot of problems in this FORUM I've noticed are related to going to the local Car Wash. And theres a lot of Electronics that's in the Engine Compartment. Especially that Module in the Front left Engine Compartment. I believe that is the Power Module. And it controls everything. It really scares me the problems people are having with new Jeeps. And again, I think its those power Car Washes.
And if you have Freedom Top, I can give advice and warning about that too.

Meh. I have crossed many a stream that is over the hood/base of windshield. No problems yet. I pressure wash engine compartment monthly...as well as the complete interior...yes, dash too!
Troy
U said the dealer blames their contracted detailer. Hold them to it and have them fix it. Period. Call chrysler if need be. Might need a new ecm, alt, (?). Good luck.
Have u tried checking the most obvious...battery connections?

It sounds like the only 'Lemon' involved is the mechanical help you are receiving.

Although your Jeep has an issue, it is not the vehicles fault that the mechanics are not competent enough to repair the problem. Don't lose faith in Jeep's, they are actually built quite well today.

'Lighting Bolt' symbols universally represent a problem in the electrical system, specifically the battery/charging system/circuit, which is not very complicated at all.

Many dealers are in the habit of hiring shop staff that are speedy at changing parts but mostly rely on 'scanners' to diagnose issues, most are much better parts changers than they are actual mechanics/technicians. (Sensors & scanners won't indicate/diagnose all problems-especially basic ones). Much cheaper to hire parts changers than actual techs, 3 to 1 was the last figure I heard. But that's the nature of business today, do more with less.

Anyone changing parts not fixing the problem at your expense, is literally training themselves on your dime. That's misrepresentation & fraud in most States.. They cannot advertise (hanging any sign is advertising) to provide a service they cannot perform, get a better lawyer..

Mechanically speaking, check charging system first - then test for faulty coil pack, spark plug, bad injector - all these things can cause misfire and are easily tested, then identified or eliminated as an issue.
There is a process that is clearly defined in repair manuals, they should crack one open for your truck..

Do you know how to use a volt meter. Has the dealer checked for foul plugs. And what have they said about the water in the cab driver side. Keep your head up, at least its American.

IT runs on like five cylinder's in limp mod then you shut it off start it again and usually runs fine but the lightning bolt stays on and a couple times going around a turn I would hit the gas peddle and the tach would drop for a second then pick up and go. It hasn't done that since the computer was replaced. Its going to rain tomorrow so the mechanic that took it home tonight will have some fun driving it in tommrow

If the vehicle is dropping into 'limp mode', trouble codes should be set, what are they?

The PCM (Power Control Module) regulates alternator voltage via the dashboard 'lighting bolt' circuit in most vehicles. Several other PCM 'functions' may run thru the dash also, so a faulty dashboard &/or bad dash connection could create havoc.

We see this on occasion from the Ford F-series trucks in our fleet.

Absent any real tech info tho I'm just reaching here, but trying to help out..

BTW, engine systems are designed to run awful in 'limp mode', including intentional misfiring, which is used to prevent overheating..

The strategy being - "better to 'limp' home, than 'die' in the field"

I've never had luck with used cars. Bought two in a role. First was a Fiero and then a Camaro. What does your Purchase Agreement say about this. It should be at the very end. Most people don't read down there.
