The center lock bolts to the wheels increase in tightness when driven even a short distance. All four of my bolts have consistently tightened to over 800 ft/lbs of torque after being installed at Porsche dealerships.  The car was delivered new in Sept 2023. The first attempt to remove the bolts were nearly impossible being over tight. The car was sent to the dealership to address this issue, to no resolve; Jan 8, 2024. Porsche - South Austin stated âCHECKED AND CORRECTED WHEEL TORQUE TO FACTORY SPEC OF 444 FT. LBS. INSPECTED CENTER WHEEL LOCKS FOR DAMAGE, NONE FOUND.â  The wheel bolts went untouched by me or anyone else until the 2 year service at the dealership (Nov 25, 2025). They found the bolts were nearly 1000 ft/lbs!! And NOW they claim the bolts are damaged; they have been untouched since the last visit. Iâm lucky they didnât break apart from the stress.  I bought 2 new center locks to replace the âdamagedâ ones, and all four bolts on the car have again self-tightened beyond 800 ft/lbs in the ~15 mile drive to my home! This is not only dangerous. Itâs been seen and identified as such before, and should be corrected as soon as possible.  Porsche told me they think a âthird partyâ damaged the bolts. Besides saying they were damaged when I first pointed out the issue to them, only Porsche -South has touched those bolts between inspections. I do not have the strength or lever long enough to apply 1000 ft/lbs. I never used a power gun to install the bolts. This car has never been on a race track or auto cross event. At only 4348 miles since new, most anything that fails at this point is probably defective. Center lock bolts that are mimicking already recalled locks, are clearly defective.
