2020 Jeep Compass

When trying to start vehicle it displays a “Service Electrical System” error followed by “Coolant Temperature Too High” my coolant gauge sky rockets red and then returns to a very low level. The vehicle has not overheated and has been parked and cooled off completely before trying to start. It is now causing my vehicle to throw messages saying my back up light, brake light, and blinker lights are out but all lights work as they are intended.

I was making a left turn when the temperature indicator shot up to red, it had been reading right in the middle which is normal. Then "coolant temperature high" lit up on the dashboard display. The car started to sputter (like shaking) as I was going through the intersection and I thought it was going to turn off completely. I hit the gas because there was still oncoming traffic and it seems like the car recovered. The gauge showing the temperature slowly went back to normal and the error light went away. The same situation happened about 3 months ago when my husband was driving. However, he was sitting at a light when the temperature went up and the error occurred. The car completely shut down and had to be restarted.

The contact owns a 2020 Jeep Compass. The contact stated while driving at approximately 30 MPH, a low oil pressure warning light illuminated intermittently, and the gears failed to shift as designed. The contact also stated that the front of the vehicle was shaking, causing an abnormal sound. The vehicle was taken to a dealer the low oil pressure sensor was replaced. After the repair, the failure reoccurred and the vehicle was taken to another dealer, Harr Chrysler Jeep Dodge Ram (110 Gold Star Blvd, Worcester, MA 01606) where the service tech was unable to determine the cause of the failure. The manufacturer was notified of the failure. The failure mileage was approximately 35,000.

While at a stoplight the engine stalled and the instrument cluster displayed a "coolant temperature high" message. After restarting the engine the temperature gauge displayed the normal mid temp. This has happened once before when reversing in the driveway at home. This scenario is identical to the open investigation at NHTSA from December 2022.

Unknown as to exact issue. In August 2021, spark plug blew (according to dealer) in the middle of an intersection after the auto “off” and the engine would not turn back on at approximately 8K miles. The spark plug was replaced under warranty. Starting in April 2023, around 31K miles, on two separate occasions after the auto start/stop is in use. It will turn off unexpectedly and without warning after the vehicle has come to a stop. Both times the vehicle could not be turned completely off and restarted for at least one minute. No messages appear on screen. Both issues appear to be related to the Stop/Start feature. Two different dealers have not been able to identify issue.

Engine temporarily shut itself off by itself in the freeway as I was slowing down pressing my brakes because of the cars in front of me in traffic hour. The car flashed a “coolant temperature too high” message then immediately turned itself off for a minute. The engine/coolant temperature gauge was normal the whole time I was driving (in between the cold and the high sign). But even then it flashed that “coolant temperature too high” message and shut itself off right then for a minute after it flashed me that sign. It was over 100 degrees fahrenheit outside and inside the car without ac it was awful. I immediately turn on my four ways but cars still kept coming up behind me even though I could not move my car. The car would not turn on. I changed gears from drive to neutral and then to park. And after a minute the car turned on again. Even with my four ways on, drivers kept pulling up behind me on the freeway despite my four way lights being on. I prayed I wouldn’t get hit and cause an accident on the freeway because of my disabled vehicle. A few drivers almost rear ended me because they kept coming up behind me. I kept pressing my brakes and tried restarting my vehicle. I was scared and almost got hit by a some cars. This has happened multiple times every year since I bought the car back in 2021. Before it kept happening at a stop light in the middle of the street and now it happend on the freeway. On the freeway I am driving between 65mph to 80mph and it stopping like that randomly made my heart skip a beat. I thought I was going to be involved in several accidents on the freeway with cars going over 65mph. The car shutting itself off messed up my steering and the braking system. It is a safety hazard. I have gone to the dealership multiple times for this issue and it still happens to me every year. I could have died or caused an accident today.

The vehicle was in motion going 40 MPH when the dashboard displayed high coolant temp. The dashboard continued to flash other warnings such as check engine and oil change required. Then, the emergency brake light was on, engine light, and oil light. This caused the vehicle to lose total power in the accelerator and partial power in the brakes. The event led my vehicle to cause a complete stop in the middle of a highway. To the resolve the issue, I powered off the engine and restarted the vehicle. After powering the vehicle back on, all was normal other than the check engine light was still on, but it did run perfectly fine. Coolant level in reservoir is normal. This instance has taken place on multiple occasions.

On 4 occasions, months apart, my 2020 Jeep Compass has given me a dashboard alert stating “coolant temperature too high” and the engine immediately stalls and shuts down. The first 3 times this occurred, the check engine light would come on and the vehicle would not restart and other alerts such as “service 4WD system” and “EBS not available” would display. At no time was the vehicle overheating or the actual coolant temperature above normal operating temperature. After sitting in the middle of an intersection for 5-10 minutes, the vehicle would finally turn on with the check engine light being off and no alerts displayed. The vehicle would then drive like nothing ever happened for a few months. The most recent time this unexpected shutdown occurred, as I slowed to approach a left hand turn the vehicle gave the coolant temperature error and shut down, losing power steering and making the break pedal incredibly hard to depress. I came to a stop in the turn lane and put it in park, only this time the vehicle could not be restarted at all and it had to be towed home and then the next day towed to the dealer for service. The vehicle is still in the dealers possession for servicing. This issue needs to be investigated and reconciled. If this were to happen on the freeway numerous lives would be at risk.
