Common issues, honestly documented.

Symptoms

• · Car sits low overnight or on one corner
• · "Suspension fault" message on startup
• · Compressor runs excessively

Likely cause

Leaking air struts (usually rear), failing compressor, or a chafed air line.

Repair path

Test each corner with a scan tool that reads ride-height sensors. Replace failing struts in pairs. OEM Continental compressors typically outlast aftermarket units.

Symptoms

• · Cold-start rattle from the front of the engine
• · P0016 / P0017 correlation codes
• · Rough idle after cold soak

Likely cause

Original plastic guide wear on pre-2014 supercharged and NA V8s.

Repair path

Front timing cover job. Budget accordingly — this is the most consequential preventive item on collector-grade V8s.

Symptoms

• · Sweet smell after a hard drive
• · Slow coolant loss with no visible external leak
• · Coolant collecting in the valley

Likely cause

The plastic crossover pipe under the supercharger degrades with heat cycling.

Repair path

Replace with the updated metal/reinforced part while the supercharger is off. Do the thermostat at the same time.

Symptoms

• · Slow boot
• · Bluetooth/CarPlay drops
• · Frozen touchscreen

Likely cause

Aging head unit and connector corrosion.

Repair path

Software reset via secondary menu; disconnect battery for 30 minutes. Persistent faults usually mean a head-unit replacement — 2017+ Touch Pro Duo units are a common upgrade path.

Symptoms

• · "Park brake fault" warning
• · Grinding when engaging

Likely cause

Actuator motor wear at the rear caliper.

Repair path

Replace the parking brake motor (left, right, or both). A 30-minute job per side with the right tool.

Symptoms

• · Water in the front footwell
• · Musty smell

Likely cause

Clogged drain tubes at the A-pillars.

Repair path

Clear drains with compressed air or a soft trimmer line. Preventive on every service.
