🔧 Top 10 Common Mechanical Issues — Root Cause ✅ + Fix 🔩

1. AFM/DoD lifter tick or misfire (V8)
   🧠 Root cause: lifter collapse, oiling issues, AFM operation wear.
   🔧 Fix: scan misfires, inspect valvetrain, replace lifters/cam if needed; strict oil maintenance; some owners use AFM management solutions (where legal).
2. 8-speed shudder (some trims)
   🧠 Root cause: torque converter clutch behavior and/or fluid condition.
   🔧 Fix: service with updated fluid procedure, reprogram/relearn; replace torque converter if persistent.
3. Transmission harsh shifts (6-speed/8-speed)
   🧠 Root cause: adaptive learn drift, valve body wear, fluid deterioration.
   🔧 Fix: scan TCM, service fluid, update calibration, repair valve body if required.
4. Brake vibration / uneven wear
   🧠 Root cause: pad deposits, heat cycling, caliper slide pin issues.
   🔧 Fix: clean/grease slide pins, replace rotors/pads, proper bedding.
5. Steering clunk / loose feel
   🧠 Root cause: steering intermediate shaft wear or front suspension play.
   🔧 Fix: inspect shaft/ball joints/tie rods; replace worn components, align.
6. Cooling system leaks
   🧠 Root cause: hose fittings, water pump seepage, radiator end tank leaks.
   🔧 Fix: pressure test, replace leaking parts, refill/bleed properly.
7. Exhaust manifold bolt break / tick (V8)
   🧠 Root cause: heat cycles causing bolt fatigue/warpage.
   🔧 Fix: replace bolts/manifold, check gasket sealing; use updated hardware.
8. Front hub bearing noise
   🧠 Root cause: bearing wear, water ingress, heavy loads.
   🔧 Fix: replace hub assembly; verify ABS sensor function.
9. Transfer case or front diff seep (4WD)
   🧠 Root cause: seal wear, venting issues, fluid neglect.
   🔧 Fix: reseal, service fluid, check vents.
10. Fuel system rough run
    🧠 Root cause: injector deposits, low fuel pressure, vacuum leaks.
    🔧 Fix: fuel pressure test, injector cleaning/replacement, smoke test for leaks.

💡 Top 10 Common Electrical Issues — Root Cause ✅ + Fix 🔌

1. Battery drain / intermittent no-start
   🧠 Root cause: weak battery, module staying awake, poor grounds.
   🔧 Fix: battery/charging test, clean grounds, parasitic draw diagnosis.
2. Infotainment glitches (screen freeze/reboot)
   🧠 Root cause: head unit software/low voltage events.
   🔧 Fix: update software, verify power/ground, replace unit if faulty.
3. TPMS warnings
   🧠 Root cause: sensor battery aging or wheel-related damage.
   🔧 Fix: replace TPMS sensor(s), relearn procedure.
4. ABS/traction warnings
   🧠 Root cause: wheel speed sensor wiring at hubs, bearing play, low voltage.
   🔧 Fix: scan ABS codes, repair harness, replace hub/sensor, verify battery.
5. HVAC blower intermittent
   🧠 Root cause: blower resistor/module or connector overheating.
   🔧 Fix: replace resistor/module, repair connector if heat-damaged.
6. Power window/lock issues
   🧠 Root cause: door harness breaks, switch failure, BCM logic.
   🔧 Fix: inspect harness in door boot, replace switch/actuator, BCM scan.
7. Rear camera not working
   🧠 Root cause: camera moisture intrusion or tailgate harness wear.
   🔧 Fix: replace camera, repair harness, verify signal at head unit.
8. Trailer wiring faults
   🧠 Root cause: connector corrosion, ground faults, blown fuses.
   🔧 Fix: clean/replace connector, repair grounds, verify trailer module.
9. Airbag/SRS light
   🧠 Root cause: seat connector issues, clock spring, sensor faults.
   🔧 Fix: read SRS codes, repair connectors, replace clock spring/sensors.
10. CAN communication codes
    🧠 Root cause: low voltage, module fault, connector corrosion.
    🔧 Fix: battery/ground first, network scan, isolate failing module per service flow.
