2018 Jeep Compass engine problems

“•Manufacturer: Jeep / Stellantis •Year: 2018 •Model: Jeep Compass •VIN: [XXX] •NHTSA ODI Complaint Number: 11771736 •Date of Formal NHTSA Complaint: October 16, 2026 I am writing to formally escalate a serious and recurring electrical and starting-system malfunction affecting my son's 2018 Jeep Compass, identified above.”

“I have a 2018 Jeep Compass that is experiencing an intermittent engine stall while I am driving. The engine cuts off, particularly when I am sitting in traffic or maintaining the same speed for an extended period of time. There is currently no check-engine light illuminated. This is a serious safety concern because the vehicle is losing power while being operated on the road. I do not consider this a normal drivability issue, and I need the vehicle properly diagnosed for an intermittent stalling/loss-of-power condition. Please check my VIN for all open safety recalls, including any PCM/powertrain-control-module recalls or campaigns, and check whether there are any applicable technical service bulletins or known issues related to this symptom. I would also like the concern documented on my repair order exactly as: “Vehicle intermittently stalls/cuts off while driving, causing loss of motive power.” Because this is a safety-related issue, I would like the service department to advise whether the vehicle should be driven or towed in for diagnosis. Please do not simply tell me there are no codes or that the check-engine light is not on. The vehicle is actually…”

“On August 25, 2026, my 2018 Jeep Compass equipped with the 2.4L engine became inoperable approximately five months after I purchased it. The vehicle had approximately 68,000 miles. An independent repair shop initially found no fuel pressure and replaced the fuel pump and spark plugs. The vehicle remained mechanically compromised, and testing showed only 99 PSI compression in cylinder 3. The shop recommended engine replacement at an estimated cost of $9,221.49. Jeep confirmed that the vehicle was associated with Customer Satisfaction Notification W20 concerning excessive oil consumption and potential engine stalling, as well as XB1, the 2.4L excessive-oil-consumption warranty extension. Jeep stated that XB1 expired on September 20, 2025. I am concerned that abnormal oil consumption or a related engine defect may have caused progressive internal engine damage and created a stalling or loss-of-power safety risk. I request that NHTSA document and investigate this failure. Jeep customer-care reference number: 97940025.”
