Was not able to resolve an ongoing issue that has led to a breach of contract with Mercedes of Beverton, OR. Leased a 2018 MB c350e from them on April 22, 2018, failed to provide me or the DMV with the appropriate documentation so that I can register and drive this car LEGALLY in my home state of California. State of California requires vehicles out of state to be legally registered within 90 days of my lease contract. They did not do this for 5 months and therefore the car had no plates the entire time. • Statement of facts completed and signed by myself or the dealer acknowledging that the CA sales tax is included in the lease payment. • A signed power of attorney from MB lessor trustee Upon receipt of this vehicle, I took the necessary steps required by CA such as paying for smog test. On May 16th during my initial visit to the DMV, I was informed that I needed the above-mentioned documents before the car could be registered. After numerous calls to the dealership, the salesman Ion assured me on June 20th that they sent the documents to my local DMV. However, after yet another visit to the DMV on July 22nd, the agent told me that they didn’t receive the necessary documents from the dealership. They did however, attempt to contact the MB dealership on July 23rd but no one returned their call. In recent weeks I have reached out to the MB GM’s office, MB USA customer care MB USA executive office, and several others, they have noted my complaints and ask me to get Dealer upper management involved. My temporary permit, which had been extended several times, expired on July 13, 2018. Needless-to-say, I had rent a car since legally I could not drive my leased car Benz. In all my years of car ownership 60+ cars, I’ve never experienced such poor customer service. This has been a nightmare to say the least. If this doesn’t get resolved within the next 2 weeks. This vehicle was turned back to Mercedes Benz at another dealership after only 5 months ownership and a $6k loss. It was worth it to get rid of this Benz from buying experience to Corporate Managers that don't help and don't care what the customer experience is! Even my pre-paid maintenance that I paid for has not been returned even after 2 months with no end in site. Worse company ever period!
