Jeep Liberty misfire problems

Filed Aug 31, 2026 · Airbags, Brakes · MO

I have owned this vehicle since 2011 and began having issues with passenger airbag light coming on intermittently or sometimes staying on during trip whether a passenger was in the seat or not. Had to install a new motor in 2025 due to antifreeze overflowing into engine components apparently after overheating even though gauge on dash never indicated issue. Squeeking sound when putting vehicle into reverse, cert mechanic installed front pads and rotors and rear brake pads and left rear brake caliper for a total cost of $620. Traveled to kc (appx 100 miles) one day later and vehicle began losing acceleration, stuttered and seeemed to surge intermitently then rear brake began locking up and smoking excessively before illuminating a check engine light. Draggin/locking rear brake broke loose on drive back home but still had check engine light. Took back to mechanic who diagnosed rapid misfire on cylinder no. 1 but was not able to trace cause. Recommended taking to dealership for diagnostic at a cost of $150 per hour. All 3 issues I am reporting are apparently pervasive with this vehicle as I have read numerous documented complaints from customers having the same or similar issues. However, the federal safety agency website indicates that there are no recalls associated with my vehicle. This is unacceptable!!

The check engine light flashes (critical error - cylinder misfire) and my car vibrates/shakes whenever I accelerate or go up any incline on a highway. I went to see a certified mechanic today (in michigan) and the mechanic said that the 3.7l engine has a design flaw that allows a large amount of carbon buildup in the cylinders, which leads to misfire issues. It will cost over $2,000 to repair this issue (12 hours worth of work - they have to take apart the cylinders and whole ignition/intake system, clean the parts, and replace gaskets). The mechanic says that my car is no longer safe for highway driving and can break down at any time. This car only has 104,000 miles. Jeep should not get away with such a horrible design flaw that will cause my car to break down.

While driving would run rough, stall out while stopped, stepping on gas bogs down the engine making the vehicle not move on highway, street driving, turning left or right. Replaced all fuel injectors fuel pump, charcoal canister, plugs and coils, still a problem took to garage stated a recall on cylinder heads.

I have had light sensors on my dash, electronic stability, slippery road. Service 4wd, and misfire #2 cylinder, and service ABS. I took it in for diagnostics they say the head gasket is blown, or it has a cracked head allowing antifreeze in the #2 cylinder. The lights come on a couple at a time, when driving, and then go ff either when I turn the car off, or a day or two later.

Check engine light is on, rough idle, no power on acceleration, vibrates, burns gas, smokes.. Had a compression test done and at the 3rd cylinder has a compression of 65.. Did some research on this after wasting hundreds of dollars and it needs new valves and rocker arm. Upon doing research I found put that jeeps from the year 2001 on up to 2012 are known for this problem! Why has this not been recalled? This is a serious safety issue not to mention very costly!!

I was driving my vehicle on the street when my check engine light came on and the car started to run rough and then the engine light started flashing. I parked it on a side street and had it towed to mechanic. I was told that the 3 & 5 cylinder was misfiring. Code p0303 & p0305 had to have spark plugs replaced along with boots & wires. My vehicle only has a little over 46,000 miles.
