Filed Oct 27, 2026 · Electrical, Engine · IL

When trying to start the jeep it says the hood is open and continues to act like the jeep is going to start over and over again! When it does start it runs rough! It’s is stating it needs coil 1 replaced which has been replaced and didn’t fix a thing it can’t be driven appears to be junk. Also the start stop has not been working at all

I am filing a safety complaint regarding my 2021 Jeep Compass Limited due to repeated coolant loss, overheating/high-temperature warnings, and eventual engine failure. The vehicle began losing coolant and required frequent refilling. The problem progressively worsened until coolant would immediately leak out underneath the vehicle when added. I paid approximately $1,400 to have the radiator replaced, but the same problem returned approximately two weeks later. The vehicle subsequently developed additional problems including shaking, a check-engine light, Cylinder 1 misfire, and diagnostic code P0117 related to the coolant temperature sensor/circuit. The vehicle also displayed a warning that the oil temperature was too high and the engine needed to cool down. The vehicle eventually became undrivable, and I believe the engine may have locked up. The progression from severe coolant loss and overheating to misfire, high-temperature warnings, and possible catastrophic engine failure is concerning. This vehicle is used to transport my children, including daily school transportation. I am concerned that a sudden loss of coolant, overheating, loss of power, or engine failure while driving could create a serious safety hazard. The radiator replacement did not resolve the underlying problem, which makes me concerned there may be a larger defect involving the cooling system, temperature control, or related engine components. I am requesting that the federal safety agency investigate whether similar coolant-loss, overheating, temperature-warning, and engine-failure problems are occurring in 2021 Jeep Compass vehicles and whether a safety defect may exist.

My 2018 Jeep Compass, with approximately 107,000 miles, has developed symptoms consistent with the oil pump/oil pressure defects reported in other recalled Jeep Compass vehicles. The vehicle frequently struggles to start, runs rough with noticeable vibration, and has displayed an oil pressure warning light. In addition, the vehicle frequently stalls or suddenly loses power/slows while driving. The stalling and loss of power have created a serious safety concern because they can occur while the vehicle is in motion, increasing the risk of a crash, especially in traffic or at highway speeds. These symptoms have become recurrent and appear to be worsening over time. The vehicle was evaluated by a Jeep dealership. The dealer scanned the vehicle but did not provide a repair for the underlying issue and instead advised us to continue adding coolant as needed. Despite this, the vehicle continues to exhibit the same dangerous symptoms, including the oil pressure warning light and stalling while driving. I am aware that certain 2018 Jeep Compass vehicles were recalled for oil pump-related defects; however, my vehicle was not included in the recall population. Because my vehicle is experiencing similar symptoms, I believe additional 2018 Jeep Compass vehicles outside the current VIN range may be affected. I am submitting this complaint so that the federal safety agency can investigate whether the scope of the recall should be expanded. The vehicle is available for inspection upon request.

At approximately 35,900 miles, vehicle failed a block test indicating combustion gases in the cooling system. Cylinder head gasket was replaced, cylinder head was machined, and exhaust valves were replaced at an independent shop at a cost of over $5,000. Shortly after, at approximately 36,300 miles, vehicle was towed in with sudden loss of power and would not accelerate. Diagnostic codes P1064 (cylinder 4 oil supply solenoid stuck), P0171 (fuel system lean), and P0304 (cylinder misfire) were found. The MultiAir/VVT actuator was confirmed to have an internal failure. Both the independent shop and a Jeep dealership parts department confirmed the component was on indefinite national backorder due to high demand caused by widespread failures of this part. At approximately 37,500 miles, vehicle failed a second block test. The cylinder head was found warped again and required a second full replacement along with motor mount replacement. The vehicle has had its cylinder head replaced twice in under seven months. Total out-of-pocket repair costs exceed $8,000. The sudden loss of power while driving created an unsafe condition. The failure has been confirmed and documented by both an independent repair facility and an authorized Jeep dealership. Check engine light was present prior to each failure event.

2019 jeep compass, 65k miles Car started having misfires while accelerating and decreasing speeds.It stayed pretty consistent at all speeds! Shortly after the car overheated and stated coolant temperature too high. Had it diagnosed and it was confirmed oil is mixing in with the coolant meaning blown head gasket and more than likely engine rebuild/new engine. All regular maintenance has ALWAYS been done. It is absolutely unacceptable that so many people are reporting this same exact issue and nothing is being done. Every other comment is someone stranded or the vehicle has shut off while driving, for the ones whose engine hasn’t failed they are on the verge of doing so. The investigation into this needs to be reopened, how is this not a major safety concern with an obvious engine defect. Is it gonna take several bad accidents, or worse a death ? This needs to be addressed immediately.

Transmission hard shift especially when cold. Makes grinding noise when shifting into 3rd. We have not taken it to a dealer cause we bought it used and it’s 62 thousand miles on the car and 60 thousand is supposedly the limit for the warranty. Car has also stalled while making turns to the left or sometimes when driving straight. At highway speeds when I have gone and tried to accelerate more I push the accelerator down and nothing happens. Then all of a sudden the car takes off with a jerk and I have to hit the brakes cause it was not expected. Auto engine shutoff failure light comes on for no reason. Continually get number 4 cylinder misfire check engine warning which disappears after the car is restarted. Consumes oil like nothing I have ever seen always adding oil. Can’t check the transmission fluid level cause manufacturer did not put a dipstick for the transmission so I have to take it to the dealer to see if that is low. Don’t need the cost just for them to tell me it’s fine.

I purchased the vehicle in dec 2018. The odometer read 40248. I had to replace the alternator 3 times. Last one in 2021. the vehicle would loose power on the road causing a safety hazard. Since I bought the jeep the vehicle would stutter when pressing the gas pedal. 2021 at 100,000 miles Check engine light came on and stalled driving home and had to be pushed out of the lane by police. Diagnosing code said misfiring. Took to a small mechanic and replaced engine. After repair still had the stutter. and a year and a half later stalled on highway. The vehicle code now says misfiring on po302. Parked vehicle for now.

Vehicle randomly overheats then gets back to normal. Variable valve actuator failed. And also causing multiple cylinder misfire. Swishing noise occurs as well.
