TIRES ARE 235/40 R18 REAR TIRES. This is the second set of these tires that have worn out after about 3500 city/highway road miles. No racing, no drifting, no tire spinning on launch. Porsche dealer replaced both sets as part of CPO process; now I need a third set. Current mileage on the car is 63590; I purchased it in Sept of 2021 with 57K miles. Tire wear is even across the tread; no alignment issues observed. Excessive wear was noted both times by the Discount Tire tech who checked the air in the tires at my request-routine for me. Last time, the tech said the tires were so bad he shouldn't put air in and I should get them replace ASAP. The danger arises from unexpectedly low mileage to complete tread loss and cord appearing without warning with the risk of a blowout at highway speeds on out of town trips. The excessive wear is being discussed in Boxster forums with no recognition that this must be a design or manufacturing defect unique to this model of tire. Please investigate.

Vehicle stuck in neutral after few seconds stop at stop sign in cross street. Was able to drive into hotel parking lot a few feet away and vehicle was towed home.

Expecting to replace battery after diagnostic appointment. I don't drive it that often and have never missed a service appt.
Vehicle (manual transmission) stuck in first gear while entering cross street. Very dangerous situation. I managed to avoid an accident, but it was a close call. The 6 speed manual transmission is unable to shift out of first gear.
