1. 1The 991.2 can weep coolant from the water-pump housing area, most often flagged on 2017–2018 cars — Porsche extended the water-pump and valve-block warranty to 10 years from new in the U.S. and Canada after acknowledging a manufacturing fault; confirm the remedy was done.
2. 2PDK-only and all-wheel drive; the twin-turbo is strong, but budget for tires, brakes and out-of-warranty PDK service, and note the shorter turbo-model service interval.
3. 3Confirm the airbag recalls were completed — a 2016–2017 airbag control-unit capacitor fault (NHTSA 19V533000) and 2018 side-airbag sensor tightening (19V179000) span the 911 range.

• 19V1790002018
  Side-airbag crash-sensor screws may be loose, impairing airbag deployment.
