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

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.

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.

Engine eats oil way to much around 709 miles it will start to roughly idle and when checking the oil levels it's 2 quarts low. I can also be driving and the vehicle will jerk when trying to get up to speed thrusting me forward like it's having trouble.
