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.

Primo Garcia offered absolutely exceptional, concierge-level service (and patience) throughout my lengthy search for the perfect CPO Taycan. More

Porsche Ontario responded

Thank you for sharing your feedback. I want to address the concerns you've raised regarding your recent experience with our dealership. As I explained during our lengthy phone conversation, we made it clear to you on multiple occasions that the vehicle remained available for sale while you continued to negotiate pricing. Our policy, which was communicated to you repeatedly, is that a vehicle is not considered sold until all required documents and agreements are finalized. Unfortunately, the completed paperwork did not arrive until after the vehicle had already been sold the day before. While I understand your disappointment with this outcome, I must address the manner in which you have communicated with our team. The threats of violence and profane language directed at our staff are completely unacceptable and created an unsafe environment for our employees. Given these circumstances, we believe it is in everyone's best interest to part ways. We wish you the best of luck in your search for a vehicle, but we will not be able to work with you moving forward or engage in further communication that subjects our staff to this type of behavior.
