Stalling after filling gas tank

I have had a few times now where right after I fill the gas tank of my 2008 Patriot the engine will stall. Typically if I am stopped at a stop light less than a quarter mile from the gas station where I filled up the engine will just die on me. It will start right back up again and I don't experience any trouble after burning a little fuel. This seemed to start after my CVT was replaced a couple months ago but I am not sure how this could be related.

I am not getting any lights on my dashboard and there aren't any engine codes being thrown. Also for the record I am not overfilling my gas tank, at least the automatic shutoff on the pump seems to stop when it should.

Anyone have any ideas about what might be causing this? It isn't a big deal really since it only happens right after filling my gas tank and I am not experiencing any other problems. Just curious as to what might be going on.

So far I haven't noticed any studdering, the engine just seems to shut off suddenly and I have to restart it again. Good to know I am not the only one experiencing this fizzlefish. I was a little suspicious since this started happening shortly after my CVT was replaced, but most likely this was a coincidence and it is probably due to the EVAP vapor cannister. Not sure I want to bother fixing that since so far I have only stalled when standing still right after fuelling.

I have the exact same issue on my 2007 Patriot. It started doing this about 2 years ago, at approximately 135k miles. I now have 172k.

A mechanic told me that the overflow valve is probably the culprit. He suspects that (somehow) it's not shutting off the nozzle flow in time, and although it isn't spilling gas on the ground it is wetting the canister. He says that throws off the air-gas calculations until the canister dries, ~ 30-60 secs after running. In the meanwhile, it shutters hard and/or stalls. His recommendation was to live with it and just manually fill up a little under full. This is because the valve can't be replaced w/o replacing the entire tank.

Please post if you find something contrary. I'd love to find an inexpensive solution.

I've been having the same problem with my 2008 Patriot for the last ~6 months, and have taken it to multiple mechanics and Jeep experts who haven't been able to figure out what's going on. Just took it in again yesterday and the mechanic thinks a new EVAP canister may fix the problem (although there's no guarantees and it's not a cheap fix). The car only shuts off after filling the tank 100% of the way full (we never top it off); i.e. we've been filling it ~95% of the way full with no problem. I think we are going to have the EVAP can fixed and cross our fingers, so I'll let you all know if that ends up remedying the problem. If anyone else figures out a solution to this, please let us know!

I have the same problem with my 2008 Patriot I bought in November for my 17 year old. After filling the tank the jeep stalled. My mechanic can't find any issues. He said to drop it off at his garage and he will fill the tank to see if it stalls. The previous owner probably got rid of the Jeep because of this problem.

Did anyone get this issue resolved by a mechanic or should I just not fill the tank all the way? I'm just worry about my 17 year old if the Jeep stalls again. It's her first car and she loves the Patriot. I feel like I've been scammed by the dealer but yet again I have no proof they know about this issue. I only bought this car in November.

I don't know your dealer from a load of hay, but I doubt they intentionally tried to scam you. They probably never observed the problem. If you got it from a Jeep dealer, they have every interest in wanting to fix the problem so you'll buy another. My Dad had a bum '66 Chevy and never got another Chevy after that (and he once worked for Chevrolet in the early 1950s). Brand disloyalty is stronger than brand loyalty!

FYI my '08 Patriot is at 170,000 miles and I've never had this problem, nor have I heard of it before on this site, so the problem doesn't seem all that common.

How exactly do you get it started again? Does it just stall once, restart and then no problem till the next fill? Or is it likely to strand your daughter in some god-forsaken place?

Thanks for the response Ignatz. After the car stalled she was able to restart it and manage
to drive a few feet before it stall again. She waited about 10 minute before restarting and was able to drive to the garage. The mechanic couldn't find the problem so we took the car home and so far the jeep is ok. The mechanic said to drop the car off the next time we need gas and he will fill it up for us that way he is there to examine what exactly happened. Hopefully we get an answer. Will keep everyone informed on this forum.

Well, its sounds like the mechanic is trying.

When you said she had to wait 10 minutes it reminded me of a likely unrelated but similar fail-to-start problem with the MIL's Saturn, usually in cold weather. The security system would disable the starter because it thought we were trying to steal it. We'd have to wait 10 minutes before trying to start again. We never actually fixed the problem, but found a way around it: we'd lock the vehicle whenever it was below 20F, even if it was in our garage. Once it was unlocked with the remote it was satisfied we were legitimate operators and it would start.

If you have remote door locks, there may be a security system connected. Cold weather is murder on security systems. Cold weather has given me various problems with 2 other vehicles (92 Jeep and 01 Pontiac).

Long shot, but a nasty way to sabotage a vehicle is to poke a rag down the filler tube and into the fuel tank. It will float around in there causing intermittent stall problems when it finds its way to the fuel line (though this is unlikely when the tank is full). Until the tank is pulled you'll never discover the problem. If you, your daughter, or the previous owner have a clever enemy . . .

Hope you or your mechanic finds a cheap & easy solution.

I picked up a can of Sea Foam today and going to see if that might help clean up things to prevent this from happening again. Will report back after a few refills of the tank on whether I still get any stalling or not. I won't be surprised if it doesn't work, but for $7 it can't hurt to try.

Hey all, I'm having the exact same issue. My 2008 Jeep Patriot stalled tonight for the 2nd time in about as many months. Both times were within a few minutes of filling up at a gas station. One thing to note is that it was at the same station both times but I think that is only a coincidence.

The first time this happened I was stopped at a stoplight and I felt the engine stop in a rough fashion. I looked at the tachometer and sure enough the engine was off. I was able to restart relatively easily after turning the ignition all the way to OFF. The second time, however, I was moving really slowly (not on a main road fortunately) and I noticed something was wrong when all of a sudden it became really hard to steer. I looked at my tachometer and noticed it sputter to 0 and the engine stalled. It was hard to restart but that may be because the engine was flooded as I was trying to move when it was stalling which would explain the sputtering tachometer.

This worries me because if this gets worse and I'm driving on the interstate or some other high speed situation then stall it could be a disaster in the making. I'll be taking this thing into the dealership the next opportunity I get and see what they say. Worst case I will get rid of it and get something else but I hope it doesn't come to that since I love my Jeep and don't want another car payment anytime soon.

Have your evaporation canister checked...it may be full of fuel.

Modern vehicles (2007+ is modern) don't like to be "over filled" at the gas pump because there is a possibility of causing damage to the air pollution stuff associated with the fuel filler system.

Could be that all these '07 and '08 fuel issues are due to something to do with that.

By overfilled I mean that when the gas pump goes click for the first time you should stop....you are full.
A lot of folks do the squeeze, click, squeeze, click thing trying to put as much fuel in as possible...that can lead to expensive repairs/replacements in your fuel components.

I am having the same issue with my Jeep. Every time I fill up the car will stall after driving about 30 seconds. Unfortunately this is just enough time to get into traffic. This could really cause problems because 30 seconds is just enough time to start merging onto the interstate. I don't trust this car anymore. Jeep really needs to do a recall for the 2008 patriot for this issue. I keep reading in various posts on-line that the only way to fix this is to replace the fuel tank. Does anyone else have any better ideas?

I contacted Chrysler a couple of days ago regarding this and pointed them to this thread as well as this one in which other people have reported the same problem:

I haven't heard anything from them yet but hopefully they will take notice since this seems like a pattern, especially for 2008 models, and could be a safety issue.

My 2007 Jeep Patriot does this and has done this for over 2 years. We only fill it to half full.

Add mine to the list. Randomly started doing this several months ago almost always after filling up and occasionally when leaving my driveway which may cause sloshing due to the ditch I have out front. It's mostly just annoying and if all it takes to avoid it is stopping a half gallon short when filling I can live with it.

I too am experiencing this exact same problem for the past year or so. Happens 95% of the time where the engine will stall after filling the gas tank. It can happen while sitting still or while driving. If it stalls while driving, the power steering and power brakes go out making it very difficult to control the Jeep. The obvious concern is that it could lead to a crash. I don't like the idea of just "don't fill it up all the way" - that seems like a cop out. I took it to the dealer after it happened the first time - they kept it for 2 days, driving it all around and were unable to reproduce it (this was before I stumbled across this forum and realized it only happens after a gas tank fill-up). I really hope that more Jeep Patriot owners post to forums like this so that this problems lands on someone's radar for a recall.
