2016 Jeep Wrangler: misfire or rough idle

Filed May 10, 2024 · Electrical, Engine · NH

Vehicle cel for misfire. Replace plugs and coils. Still happens. Dealership says it needs a new engine? My research shows that this is an extremely common problem with Jeep engines. I am aware of a class action suit regarding this issue. I’m not sure of the status. Vehicle has just under 129k miles and is therefore out of warranty. Jeep/FCA knew these engines had problems and continued to sell them without disclosing the highly likely problems ownere would encounter.

Did not fix problem and now are disassembling engine. Read many other customers with same problem, class action law suit in progress. Manufacturer knows about problem but will not tell owners.

2016 Jeep Wrangler intermittently misfires then immediately loses power and dies. Also loses power steering at the same time. It almost caused an accident and is a big safety concern. Now I drive in the right lane in case I have to hurry and pull off the side of road. I turn the key off, but then start it right back up and it drives fine. But then will happen again random. No dash board warning lights ever come on. Been to the dealer twice- 1st time they updated pcm software, this time they changed spark plugs and coil pack. Help. *also, first started happening at 104,500 miles .. took to dealer for the issue, it is still happening and currently at 107,500; happens randomly whether at 25mph or 50 mph

A common number 4 cylinder misfire that seems to common on all jeep forums. The code was found to be a no compression in the cylinder. Although so many people complain of this issue, jeep doesn't do anything about this? My engine is 4 years old and I'm being told I need a new engine and it's no longer under warranty.

After replacing the ignition coils ( twice) and misfiring spark plugs, my engine light continues to go on. After multiple computer readings, that keep saying the same thing, is not turning off. The dealer and other mechanics stated that this has been an issue in other jeeps as well. They tell me to campaign for this to be looked into. I still have 2 years of payments and want to have this resolved.

Auto trans: slight rough idle at stop in gear, engine will shut off when put in reverse resulting in loss of power steering and power brakes. Has happened multiple times when first driving out of my driveway even when vehicle has warmed up.

Within the past 6 months I have had to repair two ABS sensors, one in the front and one in the rear. This last sensor blowout happened while I was stopping at a light. I heard a grinding sound and felt the vibration in the break peddle as I tried to stop. The jeep then wouldn't accelerate properly after I got it stopped as I tried to get to the side of the road. I had a problem moving the vehicle off the road as the ABS kept kicking in and grinding me to a stop. The mechanic said that the sensor was having a issue picking up the speed of the tires. My jeep wrangler sport is a 2016 4 door model, it spent 2017 in a storage and I bought it late 2016. It currently has 68795 miles on it. In the 2 1/2 years I have had this on the road I've replaced two ABS sensors, had it in the shop for misfiring and my AC units blower motor seems to be failing. As a comparison, I have a 2010 dodge challenger that has been in for less repairs.

Misfire on cylinder 2. First time into the dealer stayed 3 days. Light came back on 2 months later. It has now been in the dealers shop for 9 weeks, with no repair to date. Searching indicates this is an ongoing issue from chrysler. Was told by the dealer there at 12k jeeps mario.wide with the same problem. Dealer reports they cannot get the part needed. It displayed no running issues and you never know when the light would be set off. It would come on under any condition, slow or regular driving.

I was driving on the interstate and the engine just died. I pulled over to the side of the road and restarted the vehicle and when I put it in gear it acted as if it were in neutral. I then shut off the vehicle and restarted it and it drove fine. This happens randomly (could occur twice in one day or not for 2 weeks) and at different speeds (city and highway). I also have had random misfire codes and camshaft position sensor codes. Sometimes the codes clear on their own and I have had to reset the codes with a tuner. I spoke to the dealer and it will be around a week before they can look at it, even in light of the danger for an engine just dying.
