2021 Jeep Compass Problems

What owners report

Owners of the 2021 Jeep Compass report a mix of electrical, cooling-system and transmission problems, with the most common theme being a sudden engine shutdown that the dashboard attributes to high coolant temperature. Complaints also describe stalling or loss of motive power at speed, a failing infotainment/backup-camera screen, and jerking or delayed transmission behavior. Reports span a wide mileage range, from nearly new vehicles to well over 100,000 miles, and many owners say dealers could not reproduce the fault.

   Electrical system

   Sudden shutdown with "Coolant Temperature High" warning

   • 18 complaints (22%)
   • median 60,000 mi at 4.3 yrs old (2 state mileage, few)
   • filed 2023–2026

   Complaints describe the vehicle cutting power or stopping while driving, with a dashboard message stating the coolant temperature is high or that the vehicle is shutting down, even when the gauge reads normal. Some owners say it restarts after a few seconds or up to half an hour, and several report the fault recurring at random with no stored codes. Owners describe replacement of thermostats, sensors and radiators, and dealers sometimes unable to reproduce or explain the failure. Reported from low mileage up into six figures, at speeds from parking-lot crawling to 75 mph; several mention hot weather.

   2 related service bulletins

   What to check: Ask whether the coolant temperature sensor, thermostat and cooling system have been serviced, and whether any stored codes were found; a test drive should include a stop-and-go stretch and, if possible, a hot day.

   “I am filing a safety complaint regarding my 2021 Jeep Compass Limited due to repeated coolant loss, overheating/high-temperature warnings, and eventual engine failure. The vehicle began losing coolant and required frequent refilling. The problem progressively worsened until coolant would immediately leak out underneath the vehicle when added. I paid approximately $1,400 to have the radiator replaced, but the same problem returned approximately two weeks later. …”

   NHTSA complaint #11762492, filed 2026-09

   “It’s happened 3 times now. I’ll be driving and everything is fine, and suddenly an error will pop up on the dash that will read “coolant temp too high” and the entire car will power down while driving. It’s almost caused me to wreck all 3 times. The coolant had been at a normal temperature all 3 times. 2 of the times it has been able to turn right back on and continue driving, 1 time I had to sit and let the car cool down for 30 minutes before it would turn back on (it was the middle of summer)”

   Electrical system

   Infotainment screen and backup camera failure

   • 16 complaints (20%)
   • median 70,000 mi at 4.6 yrs old (3 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2023–2026

   Complaints describe the center touchscreen flickering, showing colored lines, going black, or displaying text upside down, which also disables the backup camera and phone connectivity. Some owners report the problem worsens in hot weather and returns after dealer software updates or resets. Several note the screen failing after warranty coverage ended. Occurs at a wide range of mileage, often more noticeable in hot weather and after the vehicle has warmed up.

   “After going on and off intermittently for the last year, the rear view camera system stopped working altogether! There is a recall for my Year (21) and model (Jeep compass) but unfortunately my vin number is excluded from this recall and Stellantis says there's nothing they can do on their end to assist me with this issue. This creates a safety issue whenever I'm backing up anywhere. To diagnose the problem, my dealership wants to charge me $210.00 just to look at it. …”

   NHTSA complaint #11675050, filed 2025-07

   “The LCD radio screen goes in and out, mostly out. Can't see information projected on infortainment screen hence can't see for back up camera situations. If it does come on fully meaning seeing all the controls, sometimes all the letters and numbers are projecting upside down. If the car is hugely warm enough from long term driving the screen will be normal. I have read some reviews and it seems like this is a jeep problem. This issue has never been with other cars I owned. …”

   Engine

   Engine stalls or loses power while driving

   • 17 complaints (21%)
   • median 77,000 mi at 4.3 yrs old (3 state mileage, few)
   • filed 2023–2026

   Owners describe the engine quitting at intersections, at stop signs, or while cruising, sometimes with the warning lights flashing and the vehicle going into limp mode. Several say it restarts after shifting to park, others report needing a tow. Complaints mention dealers reprogramming the transmission or servicing the auxiliary battery without fully resolving the problem. Reported across a broad mileage range, often at low speed but also at highway speed.

   1 related service bulletin

   What to check: Ask for any service history involving battery, auxiliary battery or transmission reprogramming, and check that the stop-start system engages and restarts reliably during a test drive.

   “When I turned on my vehicle, I saw about 10 different error messages flash across my dashboard like it was having some sort of exorcism, and then it stopped. No errors were on the dashboard. Everything looked good. I waited a few minutes and my driveway, and then took off for work. As I was making my way out of the neighborhood. …”

   NHTSA complaint #11566686, filed 2024-01

   “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. …”

   • 7 complaints (9%)
   • median 62,000 mi at 4.4 yrs old (2 state mileage, few)
   • filed 2022–2026

   Owners report the vehicle lurching or bucking when accelerating from a stop, sometimes feeling like being hit from behind, and occasionally shifting in the wrong direction. Some describe a "service transmission" message and limp mode when climbing grades or at highway speed. Complaints mention dealer software updates and relearn procedures that did not resolve the behavior. Reported from low mileage to around 86,000 miles, often on inclines or during stop-and-go driving.

   “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.”

   NHTSA complaint #11684207, filed 2025-08

   “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. …”

   Start-stop system fails to restart engine

   • 7 complaints (9%)
   • median 38,000 mi at 3.6 yrs old (1 states mileage, few)
   • filed 2024–2026

   Complaints describe the engine shutting off at a light under the automatic stop-start feature and then failing to restart when the brake is released, leaving the vehicle blocking traffic until it is shifted to park. Some owners say the system displays a service message and that batteries have been replaced more than once. Several report disabling the feature manually before every drive. Reported at varied mileage, typically in stop-and-go traffic at signals and intersections.

   1 related service bulletin

   What to check: During a test drive, stop at a light with the stop-start active and confirm the engine restarts promptly; ask about battery and intelligent battery sensor service history.

   “My Start/Stop feature will bug out and not Start up after releasing the brake at a red light. It has happened multiple times and will display a maintenance required symbol in my dashboard until I restart my vehicle. It happens infrequently. One day it will work fine and the other day it will delay and not turn on immediately.”

   NHTSA complaint #11592329, filed 2024-06

   “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. …”

   NHTSA complaint #11571145, filed 2024-02

Buying note. Check the service records for cooling-system parts, battery and stop-start repairs, and transmission software updates, then test the screen, backup camera and stop-start behavior on a drive. Because several owners report faults that dealers could not reproduce, a pre-purchase inspection and a scan for stored codes are worth the cost.
