2010 GTI 6MT (built 11/20/09) original owner, engine mostly stock
56,500 mi
Failures:
Rear O2 sensor @ 15,000
Steering Wheel Electronics Module lost coding @ 30,000 (PITA to troubleshoot&fix)
Right rear brake rotor splash guard bolt holes corrode and comes off @ 53,000
OE battery dies @ 55,000
A bunch of TSBs over the years.
Knock wood, no water pumps, coil paks, but can feel some power loss due to intake valves clogging up.
Bought Platinum 9/90 extended warrantee after coding failure fearing for further electronic breakdowns.
