– Cost to Fix: $350–$1,200 (axle depending on parts)

10- Rear differential noise / axle issues (important)
– Symptoms: Banging/knocking from rear, sudden lock risk in worst cases
– Root Cause: Known rear axle cross pin defect affected certain GM vehicles (safety recall exists)
– Fix: Check VIN recall status; dealer repair if applicable; inspect diff fluid/metal debris
– Cost to Fix: $0 (recall repair if eligible) / $450–$2,500 (if out of recall + damage)

 Top 10 Common Electrical Issues Reported by Owners

1- Battery drain / parasitic draw
– Symptoms: Dead battery after sitting, random warning messages, slow crank
– Root Cause: Aging modules, infotainment/radio not sleeping, door module issues

2- Stabilitrak / ABS warnings (wheel speed sensor wiring, hub sensors)
– Symptoms: ABS light, traction control off, random chimes
– Root Cause: Wheel hub sensor failure, broken wiring, corrosion at connectors
– Fix: Scan ABS codes; check live speed data; repair wiring or replace hub/sensor
– Cost to Fix: $180–$900

3- HVAC blend door actuator failure
– Symptoms: Clicking behind dash, wrong temp on one side, weak airflow direction control
– Root Cause: Stripped actuator gears; calibration drift with age
