I made an appointment to have my 2024 911 serviced for its 10K service. I live in Altadena and driving to Ontario is a challenge at any time of day or night. I arrived at 9:30 (12/19) and was given a cour More

Elliot, Thank you for taking the time to share your feedback, and I sincerely apologize for the frustrating experience you had during your visit. You're absolutely right that we needed to handle this better. First, we should have communicated much more clearly about the expected turnaround time for your 10K service, especially given your request to go on a road-test with our technician to diagnose the secondary rattle concern you had. This diagnostic step would add time to the process, but that's no excuse for not keeping you informed throughout the day. Secondly, I understand why you drew the conclusion you did, and I'm truly sorry we gave you reason to question our priorities. I can assure you the order in which we complete cars has nothing to with how we are incentivized. Regardless, that's not the standard we should be holding ourselves to, especially for a Porsche owner who chose to trust us with their 2024 911. I would welcome the opportunity to make this right. Please contact me directly so we can reschedule your service at a time that's convenient for you, and I'll personally ensure your vehicle receives the attention it deserves. Again, my sincerest apologies for falling short of your expectations. Mark Marchant General Manager Porsche Ontario (909) 292-1800

Good morning Mr. Marchant, I appreciate the response. I would like to clarify a few things: I did not request to go on a road test. Even though it was appropriate, it was initiated by the Service Adviser. That said, I made it clear to the technician and the Service Adviser not to spend too much time looking for the rattle. I have been hearing it over the last 12-months and it has become a part of the car. Even though the technician heard the noise, I was sensitive to the fact that finding the actual cause can be very time consuming. With respect to the work schedule, the most problematic thing said to me by the Service Adviser was that if I would have waited for the car, vs. taking a loaner, the car could have been serviced in about 2 1/2 hours. Keeping in mind I had scheduled this service for a 9:30 AM drop off, the service was for 10K or 12-month on a car that only has 4,400 miles on it, and after I had already spent over 3-hours commuting to and from your dealership, I think you can see how I have come to the conclusion that my no-charge scheduled service dropped in priority because I chose to take a loaner. If not, please tell me how you having my car close to seven-hours by the time I was told that the car had not been serviced that it could have been done in 2 1/2 hours if I waited? Something appears to have moved my car down the list. The service manager said to me that they (Ontario Porsche) failed me. The reality is, you failed the brand. Porsche is legendary, and an experience that I have worked over 44-years as a civil servant to enjoy. What I expected was an all encompassing premier experience from the sale- to service- to getting a replacement when this lease ends. As I told the service advisor, I could have just as easily gone to Rusnak Porsche in Pasadena, which is literally 15-minutes from my home. However, I chose to take the car to Ontario Porsche out of loyalty to the dealership that sold me the car. I hope you understand the level of frustration this experience has caused me. Time is precious, and when it was all said and done I spent over fours hours commuting on a fools errand.

Mark, I want to personally extend my sincere appreciation for the extraordinary level of service I received during my recent purchase experience. From start to finish, despite minor incident, every detail reflected the excellence, precision, and dedication that I think define your team’s personal commitment. . Your leadership was evident throughout—from the professionalism and honesty, the seamless coordination and genuine enthusiasm that made this more than a transaction; it was a true Porsche moment for me. The overall experience was impeccable, and every interaction affirmed that I was in the hands of individuals who not only understand performance but take pride in delivering it. Thank you for making this a memorable and gratifying journey after waiting nearly 30 years from 911 poster to my garage. You’ve raised the bar for what a premium automotive experience should be. Warm regards,- King
