Adaptive Cruise Control problems of the 2021 Porsche Cayenne

Vehicle information: 2021 Porsche Cayenne e-hybrid (VIN: [xxx]) description of defect: while operating the vehicle, the steering column bolt physically backed out and detached, causing an immediate, complete loss of steering control. This exact mechanical failure mirrors NHTSA safety recall 21v-493 (Porsche campaign amb4), which addressed loose, under-torqued steering column bolts leaving the factory. My specific VIN was excluded from the narrow initial recall population, proving a factory tracking failure by the manufacturer. The authorized Porsche dealership confirmed the failure stating the bolt backed out due to "vibrations. " a vital steering bolt backing out under normal road vibrations on a 2021 luxury vehicle is a severe manufacturing defect and a life-threatening public safety hazard. Injuries/crash: no fire: no speed at incident: 25 mph information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Much like thousands of Cayenne drivers, I am constantly let down by an ongoing issue with adaptive cruise control failures with an error message that reads, “adaptive cruise control unavailable. ” this may cause serious injury or death if not repaired as vehicular collision rates increase dramatically to no avail. Porsche dealers are notoriously recalcitrant about taking adequate responsibility for these failures. The cost of repairing Porsche’s poor craftsmanship is either prohibitive or they are disinterested in repairing these problems within an acceptable timeframe. It is long past due for the federal government to intervene and compel Porsche to recall and repair their adaptive cruise control failures. I had my cameras recalibrated three (3) times in three (3) weeks and yet the problem persists without meaningful redress. Help!.
