•Inspect the coolant reservoir closely for any oily brown or grey sludge that would indicate EGR cooler failure
•Check the oil level and condition — milky or frothy oil signals coolant contamination; ask if oil consumption has been noticed between changes
•Scan for all stored and pending fault codes, paying specific attention to EGR, PCV, and oil pressure related codes
•Test drive at highway speeds (90+ km/h) over uneven road surfaces to check for steering death wobble symptoms
•Verify all open recalls have been completed — specifically track bar bracket weld, door latch, and transmission recalls
•Inspect the engine bay for any oil residue around the valve covers, PCV hoses, and intake manifold indicating PCV or oil separator failure

Inspect and replace as a maintenance item to prevent oil consumption and EGR fouling
80,000 km
EGR Valve
Inspect for carbon buildup and oil contamination; clean or replace as needed
80,000 km
Front Track Bar and Suspension Bushings
Inspect all front suspension components for wear, especially if highway wobble is noticed
50,000 km
Cylinder Heads
Monitor coolant level and quality; address any EGR cooler leak immediately to avoid head damage

Front Track Bar Bracket Weld
Improperly welded front track bar brackets may cause the track bar to detach, resulting in loss of steering control
Rear Underbody Ladder Rail Corrosion
Rear underbody ladder rail may corrode, potentially reducing structural strength of the vehicle
Right Rear Passenger Door Latch
Door latch may not be in the correct position, increasing risk of door opening while driving
Automatic Transmission (PowerShift)
Transmission output shaft snap ring may not be fully seated, potentially causing loss of drive or freewheeling condition
Driver Seat Belt Buckle Mounting Strap
Seat belt buckle mounting strap may fracture, reducing occupant protection in a crash on right-hand-drive vehicles
