2021 JEEP COMPASS Engine Problems

Multiple times now at random, car will go from normal temp to overheating on the gauge for a moment. Shuts down in doing so regardless of being driven. Then will instantly think its cooling back down to normal. When it reaches normal it resumes normal driving abilities. While the temp is going up and down on the gauge the center of the cluster tells you "high coolant temperature". No codes or pending codes can be found. Thermostat housing and sensor have been replaced and still occurring at random. Researching online forms, lots of complaints of same issues with no resolve, spending thousands of dollars and trips to dealers and shops to not be resolved. This is a huge safety hazard as you can not move out of the way of others when it happens and occurs both when driving and stopped situations.

Purchased Jan 20 2024 Battery issues started in April 2024, battery started melting a particular component, i had to replace the battery, the melting was still happening, I went to another jeep location, to get a fuse component that keeps wires separate, the melting still happened. I told the original Jeep dealership about each thing, they told me to bring it in finally and told me I had to pay for a wire harness to be run throughout the car, 3000, to 1800, and then 0, for a "malfunction they found and fixed" After Wire harness situation and price de-escalation after i told them they shouldjust take the car back because i dont have 3000; the start stop now not cooperating, has been happening since Aug 2024 in daytime with lyft rider in car. Stopped for a few months then repeated in October at night with other guests in car. Today (07/14/2025) Before 2 shift of lyft (before 7:50pm) The car stopped 6 times, 2 times with 2 different lyft riders in car. 4 times by myself, 1 time on the highway 2nd to 1st lane, with 18 wheeler behind me. This time it started back immediately but with 2nd passenger in car and 3rd time on my own it took several minutes before turning back on. Car stopped driving again today 07/15/2025 (recorded video) Now the car has a serv 4wd and the engine light is on, and I dont know whats wrong with the car. Its stressful, and I'm ready to give the car back for trade in value. Car still stops when it wants, its difficult to get a video as its happening, but the car just starts shaking, and stops driving no matter where I am. Everything will be easier to explain over the phone or in person, I am very scared of this car, this is my only source of income and now the Check engine light is on and I don't know whats wrong with the car. I've never had this many issues with a car and its the youngest car I've had. Ive seen many complaints about Jeep compass in particular after 2016. Having more problems and all similar to each other as the years go by.

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.

While driving my vehicle the parking brake engaged itself and my vehicle stopped suddenly without me engaging the brakes. I took the vehicle to the dealership and they stated it was an issue with the emissions system that caused the vehicle to do an “emergency stop”. I paid the amount required by the warranty and they stated they fixed the issue. However, while driving in the freeway (approximately 75 mph), the vehicle began to have the same issue and began to stop while I was driving. My daughter and myself were in the vehicle, during high traffic and we were fortunate not to be hit while driving when this happened. I have contacted the dealership again to have them inspect the vehicle again. I am concerned there is a manufacturing issue that is causing this problem and I am afraid to drive my vehicle especially with my children in the car.

I have replaced both batteries and the alternator. The stop/start light comes on and the red warning to pull over safely the vehicle will shut off soon and the engine light comes on. The vehicle is now telling me to service transmission. The dealer doesn't know what's wrong with it. I want this taken care of.

My 2021 Jeep Compass Trailhawk has been in very good condition until the ac recently just started to blow hot air. When I took my jeep in for a routine oil/filter, my local auto mechanic said that upon visual inspection the a/c clutch (part of the a/c compressor) was melted and that I would need a whole new a/c compressor assembly, possibly replace the drier, and completely flush the system. I can't believe that for a fairly new car in very good condition this type of problem shows up. I called Jeep and they said that there is no recall on the a/c compressor for my jeep. However, my mechanic that is now working on fixing the issue said he has to wait a few days for the compressor kit parts as it was on backorder, so there must be other similar issues ongoing. I would like to know how I can get reimbursed for a problem that should not be happening with a 2021 Jeep in very good condition? I am not sure if this is a jeep class issue.

Repeated High Coolant Temp notice. Has happened three times in 3 weeks. Last two times have happened within two days. Happens when Jeep is at about 40 mph. Jeep shows high temp warning and shuts off causing great concern for my families safety driving in 40 mph traffic. Repair shop can’t explain repeated issue.

In 3 months later that we got the jeep. The seat spring for reclain go off, later 1 year the motor mounts have alot of noise with the change of speed, and the suspension feel horroble, i been driving like that few months like that and we dont know about this page can we report all this issues.

While Auto start stop is active, and when the vehicle comes to a stop the engine stops but then doesn't restart like it's supposed to, the cluster says vehicle needs to be restarted, then after putting shifter into park I can restart the vehicle normally, but this has happened 3 times now at busy intersections causing my vehicle to block traffic when the light turns green. I have to remember to manually turn Auto start stop off everytime I start my vehicle to prevent this from happening or keep my climate turned up since the auto start stop won't engage while cooling or heating the cabin.

When stopped at a stop sign (on a slight incline, if that could be a factor), the Compass suddenly lost power. No reaction from pressing the gas pedal at all. In Drive or in Reverse. The Check Engine light came on and the temperature gauge went all the way up. Putting it in Park and restarting cleared the Check Engine light and the temperature gauge was right back to normal. Almost like nothing had happened. Thankfully it was a small intersection with no other traffic. But could this happen on the freeway?

On multiple occasions my 2021 Jeep Compass will have a "Coolant Temperature to High," and then shut my car off. So far I have been able to turn it off and it comes back on. I have taken it to our local Jeep dealer and they basically said there is nothing they can do. The safety issue is that it has just stopped while I am in motion in the middle of traffic risking a collision from the sudden stop. The dealer had it for 3 days and was unable to recreate the problem or find any issues. My Jeep worked fine with no other issues. It has never missed a maintenance appointment and never caused other problems.

The Jeep's engine decided to shut off at a red light. This jeep has the automatic shutoff for the engine when idling too long. I could not restart the engine. I blocked 2 lanes of traffic, and was unable to push the vehicle out of the way. I Tried restarting the engine several times. The accessories would come on, but the parking brake would NOT disengage and I had several issues trying to get the shifter into neutral to push the car out of an intersection. The fire department lucky was behind me after this happened, and helped me so did local police. 5 different people could not get the car to start or engage into neutral and disengage the parking brake to move the vehicle to a safe location. This was a rental so lucky I am not the owner of a failure of a jeep. This was an emergency situation while it was raining in traffic at an intersection. Police called a tow truck to tow the jeep out of the intersection because it was inoperable at this point. This is the strangest issue I have ever had with a vehicle and I am a automotive mechanic. Jeep had only 50,000 miles and no previous issues. Engine light was illuminated and I didn't have a scan tool with me (out of town). The vehicle was taken to a service shop requested by the rental company. We never knew the root cause. My advice if you have to spring for a jeep go for a bigger and better model. These and the patriots are the worst jeeps in terms of reliability.

My 2021 jeep Compass transmission and front camera has been causing me problems. My car for months has been jumping out of gear and jerking forward. The jerk get to a point where it feels as if someone just hit me from behind. These jerks almost caused me to get into about 3 accidents where I almost hit the person in front of me. In addition one time when I was at a red light and switched from brakes to gas as I was in drive my car did not go forward but reversed instead. My car has been in the shop for over 150 days with 7 different service orders. They tried to fix the jerking but was unsuccessful since it would go away for a short period and then get worse each day. Now for the front camera when I first bought the car about brand new I turned on the lane departure warning and a light popped on saying that it was not working. They replaced the camera and now I had a forward crash collision light and crusie control light turn on which has to do with the front camera and was just switched out again. My car is still in the shop after being there for over 2 months and the jerking still needs to looked at and addressed as well as the car driving in reverse.
