The rear air springs can leak, causing the vehicle to sag and the compressor to overwork and fail. Symptoms include a 'Suspension Fault' warning, continuous compressor cycling, and a noticeably lower rear end. If ignored, the compressor can burn out and the rear axle may bottom out, affecting ride quality and safety. Repair typically involves replacing both rear air springs and possibly the compressor.

The Jatco 7-speed automatic can develop a shudder or harsh shifting due to degraded transmission fluid or valve body wear. Symptoms include vibration during upshifts, hesitation, and clunking. Ignoring it can lead to valve body failure or internal damage. A fluid flush and TCM reflash may fix it early, but a valve body replacement or new transmission might be needed.

The InTouch dual-screen system can freeze, show a black screen, or become unresponsive, sometimes blocking the backup camera. This is often due to software bugs or failing hardware. A hard reboot may temporarily fix it, but the head unit may need replacement. Since the backup camera is affected, this is a safety concern.

A parasitic draw from the telematics or body control module can deplete the battery within days, even when new. Symptoms include needing frequent jump starts and overnight voltage drops. Diagnosis involves testing parasitic draw and may require reprogramming or replacing the faulty module. Expect to pay for battery replacement and diagnostic labor.

The power liftgate motor or actuator can fail, causing the tailgate to stop midway, not respond to buttons, or make clicking noises. This is often due to a stripped gear or leaking strut. Without repair, the liftgate may become stuck, making manual operation very difficult. Replacing the actuator motor costs a few hundred to over a thousand dollars.
