2021 Jeep Compass Powertrain & Transmission Problems

Every single time I seen the climb McDonald pass in Helena, Montana the car freaks out says service transmission now no matter if I do it at 55 miles an hour or 75 miles an hour, which is about as fast as it’ll go up the pass, it goes in the limp mode, shuts off the fuel pump says service transmission now every single light on the dash that could come on comes on. I don’t know what’s going on with it. I’ve taken it to the dealership. They can’t seem to figure it out.

For 6months I have a low oil pressure light come on before my oil change is due. Dealer has ran 3 oil consumption test pass/fail/pass the next one will fail as I had to add 2 quarts or oil this week and my oil change isn’t due for 2k more miles. There is no leak visible so it must be within the motor. As well as I have already replaced start/stop battery as well as main battery bc if the start/stop and it hasn’t been a year and the lights are back on and I can’t engage it. The oil issue start before the warranty went out the first time. Now I have no warranty and have to feed the car oil. It is ridiculous. This needs to be a recall. 2018 had a recall for this same oil issue. Now we need it for newer models.

Several times a year since having my 2021 Compass, as I'm driving my car shuts off out of no where and a message on my dashboard lights up in regards to the coolant system. The car is never overheated when this happens and both of my batteries have been changed. It has happened to me in the middle of going through intersections, at stoplights, and while driving. It is NOT SAFE to have your car shut down without warning!! I have to put the car in park and restart and it starts up right away each time. There are SO MANY threads of this same complaint and customers having their Jeep dealer look at it with no resolve from any comment I've read. Please help fix this unsafe issue!!

Was backing out of parking spot this morning and got error message saying “coolant temp high” and vehicle locked up. i shut off and turned back on and it was fine. checked everything out that needed to be. read online that this has happened to other people with the same vehicle. this is a safety risk and i do not feel safe driving on a highway. or in the snow this winter.

When I was driving all a sudden it started having a weird chugging feeling. I was going 40 MPH. Then when I got to a stop sign, my vehicle completely shut off. I have to hit the button to turn back on as it was not the Auto Start and stop feature. I made it home and as I pulled into my driveway it shut off again. When I start it, just it warming up it shuts off. When I come to a stop sign or traffic light it shuts up in the middle of the intersection. All while this is happening the emergency brake flips on without me turning it on. I have to wait 2 weeks to have it looked at by the Jeep Dealership. My safety and daughters safety was put at Risk because anyone behind us could hit right into the back of us while it malfunctions or oncoming traffic could hit us while it stalls while turning in a turning lane. I did take it to a repair shop and they couldn’t pull any codes as it was locked out but it was reproduced and shown to them the malfunction. There have been no warning lamps, messages, or other symptoms of problem prior to the failure besides 2 months ago, I was reversing slowly out of a parking spot at Maverick and it felt like something hit the back of my jeep. But no one had. Not sure if this has anything to do with the problem occurring now. Both very concerning. Miles at that time was 34056 and miles as this issue happening is 37000.

A common problem, which mine has, is a growl in the rear end at around 30mph. In forums I have seen people get a software update to fix, but it just changes the problem to around 50mph. If I drive with the traction control button off, or put it into manual mode, the sound goes away. On the forums the only fix is to replace the entire rear end. It's done this since I got it at about 20,000 miles. There are also clunks in the front end. The steering rack is designed to not be serviced by the consumer and you cannot replace inner tie rod ends. I don't believe there's any other vehicle designed this way. You have to replace the whole rack. One way for the dealer to make sure you come back for service. The plastic sway bar links go out under 40,000 miles and result in sloppy steering that could be dangerous. Again, on the forum boards, people have been replacing with MOOG that are a quality product and not plastic. The parking brake engages for no reason while the vehicle is moving. The auto start/stop feature is dangerous and nearly got me into an accident, twice.

I have a 2021 Jeep Compass and have been experiencing transmission bucking ever since purchasing out my lease. It is a known issue to Chrysler but they refuse to issue a recall. I have gone to the dealer twice so far. Once, they did a software update for the transmission per a bulletin that Chrysler posted for hard shifting complaints. That did nothing to fix the problem and it only got worse. The second time I took it to the dealer, they said they found nothing wrong and did a "re-learn" on the transmission. Again, it didn't fix anything. Why can't they figure this out? I have 79,000 miles and it sounds and feels like this transmission won't last 100,000. The transmission bucking causes the vehicle to shake and jerk forward when accelerating and braking.

I PURCHASED THIS VEHICLE IN JULY 2021. I DRIVE IT 2-3 TIMES PER WEEK. EACH WEEK I PUT IN BETWEEN $15-$20 IN GAS TO BRING THE FUEL LEVEL BACK UP TO THE FULL MARK. THE JEEPS DOES NOT HAVE GOOD FUEL ECONOMY. IT DEFINITELY DOES NOT REACH 22-25MPG. I DRIVE IT ABOUT 30MINUTES EACH WAY; WITH A FEW STOPS IN BETWEEN AT ABOUT 40MPH. ALSO, THE JEEP MAKES A LOT OF NOISE TO CLIMB STEEP HILLS. THE NOISE ALMOST SOUNDS LIKE WHEN YOU PUT THE CAR IN A LOWER GEAR AND THE CAR IS TRYING TO REV UP TO THE NEXT GEAR.
