One problem related to engine noise has been reported for the 2018 Jeep Compass. The most recently reported issues are listed below.
I started my car like normal and reversed and drove forward down street. I noticed the car kept making jolting motions. I came to a stop sign and as I began to take off and was in the roadway the parking brake engaged and the brake and gas pedals locked up and the car slowly came to a stop. I put the car in park and tried to disengage the parking brake. It turned off but the brake and gas pedals were still jammed. I turned the car off and let it sit for a minute and pressed the power button to try and restart the car. It started making a noise as if the battery was dead and shut back off. I let it sit for a bit longer and tried again. This time it did the same thing but eventually turned on. I then put the car in drive and proceeded to press on the gas to see if it would move forward. It did but happened again at the next intersection I had to stop at. Every time this would occur it would nudge forward just enough for me to be in the intersection and it would take a couple tries to get the car to restart in order to move. This problem continued and finally a light popped up that said "oil pressure low" so I checked the oil and it was just about empty. I had just had the oil the oil changed a couple weeks before so the oil should not have been anywhere near empty. I replaced the oil and the problem stopped. I have been making sure to check oil daily and replace as needed but now the car is jittery at times.
