Electrical System and Sensor Failures
The 2022 Compass is plagued by electrical malfunctions including backup camera going black, automatic headlight warnings, false forward collision warnings, unexpected chiming, and dashboard warning lights activating without cause. The auto start-stop system frequently malfunctions with warning indicators. Some vehicles experience complete electrical system shutdowns.
Reprogram the Body Control Module and sensor modules with updated software. TSB 08-032-22 covers electrical system diagnostic procedures. Replace faulty sensors as identified during diagnostic scan.
Est. Cost: $100 - $800Uconnect and Infotainment Glitches
Owners report continuous Bluetooth disconnections, remote keyless entry intermittently failing, the alarm system triggering randomly, and the speedometer display resetting to zero while driving. The Uconnect touchscreen becomes unresponsive or displays incorrect information. Door locks may operate erratically.
Update Uconnect software and reprogram the Remote Keyless Entry module. TSB 19-002-23 addresses RKE function failures and key programming issues. Replace the radio module if software updates do not resolve the freezing.
Est. Cost: $0 - $1,000Transmission Shudder and Premature Failure
The 9-speed automatic transmission exhibits shudder during acceleration, rough shifting between gears, and delayed engagement. Some owners report complete transmission failure requiring replacement as early as 15,000 miles. The transmission may slip into neutral or fail to shift out of park.
Reflash the TCM with updated calibration. If shudder persists, replace the torque converter. TSB 21-015-22 addresses transmission shift quality. Full transmission replacement is required for internal failures.
Est. Cost: $0 - $5,000Outer Tie Rod Noise and Steering Issues
A clunking or popping noise from the front end during turning is caused by dry outer tie rod ball joints. The noise worsens over time and can be felt through the steering wheel. Some owners also report loose steering feel and uneven tire wear related to tie rod deterioration.
Remove, grease, and reinstall both outer tie rod ball joints per TSB 19-001-23. If the ball joints show excessive play, full tie rod replacement and wheel alignment are required.
Est. Cost: $100 - $500False Park Assist Warnings
The front park assist system triggers false warnings when no obstacle is present, causing the vehicle to beep and flash alerts while driving normally. The system may also fail to detect actual obstacles, giving drivers a false sense of security. This issue is linked to faulty Park Assist Module software calibration.
Reprogram the Park Assist Module (PAM) with the latest software version per TSB 18-020-22. Clean the ultrasonic sensors. If the issue persists after reprogramming, replace the PAM module.
