Error message “High coolant temperature”
21 - 40 of 44 Posts
I'm having the same issue with my Jeep Compass 2019. Engine stalled 3 times already this month after a quick error message "coolant temperature too high" was displayed and immediately disappeared. But enough for the engine to stop completely. It happened at freeway exit ramp, driveway ramp, traffic light. Someone will get killed. I called three dealers. No one has appt available before March 11th. I can't keep driving like this. I called my old mechanic and he said that only a dealer can do a software update since it seems it is a glitch. I tried Jeep customer service number that the dealer gave me and the message says: Do not leave a message here. Somebody needs to take this seriously before it is too late. I need somebody to help me.

I found this thread back in May 2021 when I started experiencing the same issue with my 2019 Compass Trailhawk. I contacted Jeep Customer Care (Jeep Wave) and had it brought in to the dealership, now multiple times with no resolution. Bought a code recorder that was suggested by the dealership, brought it in and the code was something weird and no help. The issue has now risen to interstate speeds and luckily we were not hurt. Currently waiting on a call back for the buyback program. We have had 10 months of issues and none of the techs can replicate while in the shop. We have video proof and images, so I will be fighting this. Customer Care has given us an extended warranty since they had to close out my case. I have had 3 separate cases now for the same issue. I do wonder if the heat is a factor or maybe just a coincidence?

So I've been driving myself crazy with this same issue. My 2019 Compass Altitude begain shutting down last year with the high coolant temperature warning; it happened at highway speeds and shut down on the Tappan Zee bridge when I was bringing my 1 year old to the ER at 2am.
I began taking it in to the dealership every time it happened and had a dashcam installed on the instrument panel to record the lights and proof the car shut down with all the lights and loss of RPM since the delaer kept telling me they couldn't "replicate the issue" and the car never stored a code.
I had my PCR, PCM, battery terminals, auxillary batteries replaced, and coolant flushed/replaced over the course of a year. My Jeep has 20k miles on it right now.
I am currently going through the FCA Repurchase/Buyback program right now after filing a Consumer Complaint with my State since JeepCares/FCA refused to help and my case manager told me I was crazy. After submitting my dash cam videos and pictures to Jeep and the State; I was told it would be Lemon'd and bought back.
I was told by FCA they would refund my loan minus the mandated usage and any interest paid within 30-90 days. That was 5 months ago and they've stopped communicating. I've submitted all of the paperwork to FCA as requested and I'm left with a lawn ornament. I won't drive the Jeep since it keeps shutting down and I have 2 small children. I purchased a new vehicle with the expectation this one would be repurchased.
This is a model specific issue FCA refuses to recall and until someone dies, we're all left in this weird limbo

It looks like you've exhausted the reasonable routes to satisfaction. Did you get the buy-back agreement in writing? If so, maybe a lawyer can take that and run with it. If someone told you something, that can easily be denied so your best bet is to go back to the state and tell them where you're at. If your state consumer affairs department is good, they should get action. Remember to document everything. Even keep a diary of oral contact -- date, time, person's name and title, and a summary of the conversation. If you contact a lawyer they can give you far better advice than I can. I'm just a vehicle owner like you.

Having the same issue. It started very rarely, just thinking it was an anomaly, then increased in all seasons. When the gauge goes high and at a stop light, engine shuts down and will not start for a few minutes. During driving, the engine becomes rough sounding and slows up. I took it to a mechanic who ran the codes and replaced the coolant tank cap. It didn't solve the problem. A few days later it continued. Reading these posts, I don't see a solution.

Hey! I just had all of this happen and more. Turns out that when the batteries (yes 2, got to love the auto off feature... Nope!) are low the system starts throwing weird codes like the coolant temp too hot, air bags deployed, rear blinkers aren't working, auto off malfunction. All these codes with in a 10 minute period while trying to start our Compass. Also, I talked with a mechanic friend about what happened to us and everything you guys commented, he said that the alternator might be going out if it's shutting off while you're driving. The alternator keeps the battery charged but if it's not working properly and your batteries are low then it's going to shut your vehicle off. A lot of auto part stores or tire shops can do the check for your starter, alternator, and batteries if you just take it to them. I would call a head and see if they offer it. I really hope this helps you all! I appreciated reading all your comments and to the person that suggested reporting to the NHTSA thank you! We did that too. What the car is doing is so unsafe and they need to come up with a fix for it. Good luck you guys!

Here we are in November 2022 and our 2020 Jeep Compass Limited has experienced the same issue multiple times lately with the high temp light coming on and shutting the vehicle down. It is extremely unsafe and was wondering if there has been any resolution to any of the issues documented on this forum yet?

Hi Guys I recently had the same problem, the dealership checked it for a few days under warranty and they changed the pcm module, it's been several days now that it doesn't fail, it seems that the problem was solved
Presuming you've checked your coolant level, then as @MaggieA suggested, it could be a bad aux battery. A bad battery (or any other electrical problems) can make strange warnings appear. The aux battery is barely good for 3 years, even less if operated in a harsh climate. Two winters in northern NH killed mine in 2 years, but I was well past the warranty mileage so it was on my dime. When the aux wears down, it starts sapping the life out of the service battery. Do you get any auto/start/stop warnings? I ignored the warning and just figured it was the cold weather cuz my start/stop was working fine -- only later I realized it was killing my service battery.

The change of the pcm module did not solve the problem, yesterday it failed again. I don't know what else to do, because the dealer assured that it was a fault in the PCM
Check the aux battery! That's what my post was about.The change of the pcm module did not solve the problem, yesterday it failed again. I don't know what else to do, because the dealer assured that it was a fault in the PCM

Thanks, How can I check it myself?
Honestly I've never checked mine, or any battery for that matter. In conventional set-ups either the car started or it didn't, so it was obvious. The Compass is the first vehicle I've had with an aux battery.
Many parts stores will check for free because, of course, they want to sell you the parts you need.

Hi
Yesterday the agency changed the auxiliary battery for warranty, today my compass failed again
I see that the voltage on the instrument panel is around 12.8v and sometimes it goes up to 13.5v or 14.0v a few times. that's right?

I have not confirmed it, but it has not failed for days, the last thing we did was change the ibs sensor
