•Run a full NHTSA VIN recall check and confirm all five recalls have been completed at a GM dealer before purchase
•Start cold and listen for AFM lifter tick or tapping, any metallic ticking is a serious red flag requiring immediate investigation
•Demand full service records proving oil changes every 8,000 km or less with Dexos1-spec full synthetic oil
•Ask whether an AFM disable module or range AFM disabler is already installed, if not budget €150-300 to add one immediately after purchase
•Connect an OBD2 scanner and check for any stored or pending misfire codes, especially on cylinders 1, 4, 6, or 7
•Inspect transmission cooler lines under the vehicle for any signs of fluid seepage or recall non-completion

AFM lifters (all 16 AFM-specific lifters)
Install an AFM range disable module shortly after purchase, budget for full lifter replacement or conversion to non-AFM solid lifters on a high-mileage example without documented AFM disable
80,000-150,000 km
Camshaft (lobes worn by failed AFM lifters)
Inspect camshaft condition whenever lifter noise appears, replace cam during lifter job if any lobe wear is found
100,000-180,000 km
Intake valves (carbon deposits from direct injection)
Walnut blast intake valves or perform a chemical decarbonization service
100,000-160,000 km
Transmission cooler lines
Inspect and verify recall completion, replace lines if any seepage is found
60,000-120,000 km
