The distinctiveness of a Mercedes-Benz vehicle begins with the quality of its Mercedes-Benz parts and accessories. Every component is artfully designed and promises superior performance, reliability, and longevity. Aftermarket parts won’t do your Mercedes-Benz justice; they simply aren’t strong enough to accommodate its advanced engine, transmission, brake system, etc. for long periods. They also don’t offer the same level of fit of the genuine parts you can find at our Mercedes-Benz parts center, which have been fabricated to precisely fit your vehicle instead of appeal to mass-market options. That’s why we recommend nothing but OEM parts to our customers for all their services, repairs, and enhancements!
Perhaps best of all, each part in our inventory is backed by a Parts Limited Warranty, doubling the peace of mind you can only get from buying Mercedes-Benz original parts. The Mercedes-Benz Parts Limited Warranty includes the protections of:

Activating Your Key
After we receive the appropriate documentation, we’ll need to synchronize the new key with your car. We can’t program your new key remotely, whether you live nearby in Ontario, or further away in Rancho Cucamonga. Programming a key fob requires that the vehicle be in the same vicinity as the key fob. Contact our Mercedes-Benz Parts Center with questions about Mercedes-Benz key fob replacement cost and more!
Ron Did everything I asked and handled it in perfect timely manner. Every thing I needed was addressed. Blah blah blah blah blah blah blah
Scott Bi and the team at Mercedes Benz of Ontario blew me away! I’m so happy with my new 2021 GLA! Scott was a kind and professional sales person who ensured to answer ALL of questions during the process. He never gave up and did all he could to meet my needs. Scott has been so attentive to follow up and make sure all is going well with my new GLA! Thank you Scott and team for all you do deliver top notch service!!
Tony is great ! Everything is great so far. But But After service my car was washed, its unbelievable car wash is terrible worse ....unhappy on this only
The service was great! Ron was very helpful and helped me with future repairs. Now I can get my car repaired one item at a time. I was disappointed that you were not thinking of your customers enough to lower repair costs for a short time because of the pandemic and help those who were trying to keep their cars serviced and running but may have lost their wages or had to take a pay cut! Just something to think about for future global problems!
Sales Mgmt. was great to work with, didn't take typical time frame and just overall expectations were more than met.
Ibraham, Fadi, and Yogi truly made my first luxury car purchase experience as easy and comfortable as possible. From start to finish, my dad and I were treated respectfully and were tended too throughout the entire process. Everyone was very nice and willing to go over and beyond for a sale that would leave me happy. I cant say enough positive things about this dealership.
Ashin and Addy were amazing and they did all their best to make the deal
Work
I have brought my 2 vehicles to this dealership for service. They are always courteous, professional and friendly. I feel they do a quality job with their repairs and care of my vehicles. With the Covid pandemic they utilize good cleanliness practices.
Tony is an amazing service advisor, very professional!! Thanks for the great service. I would highly recommend anyone who needs service to come here. Thanks
Very friendly staff. Was able to get me into a loaner car when Uber was too expensive. Very detail oriented. They let me know other work that needed to be done but not pressured into doing the work at their establishment.
Eric Anaya was exceptionally helpful with everything and I appreciate everything he did including calling to verify satisfaction after.
Joseph and Vanessa were also very helpful with assistance.
My service was done in a timely manner and the car was cleaned and deliverd perfectly.
Great customer service very helpful and so nice always welcoming and helpful
Exelente service like always I been a customer for the last three years and each time I go for service I have always have a smooth transaction with my previous advisor gerald corona and now with the new advisor Erick
I love this dealership. I’ve owned my Mercedes for over 13 years and just recently started to bring it to Ontario. The workmanship and attention I received at this dealership is most exceptional. Totally appreciate this service department. I tell all my Mercedes friends to go get their service from ontario.
Didnt rate the quality of repair because I really dont know. It was a safety belt issue that I never had a problem with.
Clean facility. Friendly staff. Excellent quality of repair. Overall exceptional service. Id recommend taking your Mercesdes Benz of Ontario for your Mercedes needs.
I was approached within seconds for my appointment
Fantastic experience, perfect and fast every part of the transaction. Very knowledgeable sales agents and finance managers. Personal touch from the GM
I had a great experience at Fletcher Jones Ontario. Ali Mahmoud found me the exact car I wanted with the options package with a fair price. Excellent customer service and attention-to-detail. I highly recommend this dealership.
The service was excellent. I have been getting my car serviced at this dealership since it open. Everything has always been at the highest level of service.
I regularly take my S5 50 into the dealer in request to fill Gibson as my service advisor.
Phil Gibson always provides above and beyond service!
Great experience and very nice employees. I would definitely return. They took great care of my car and offered a relaxing waiting area while the car was in service.
The staff is great, courteous and very attentive from the moment you srrkbe until they return your vehicle freshly washed. I realy like the convenience of the loaner car program, saves me so much time. As for the service while I find it expensive I think that you get what you pay for
Great working with Mike Doehla, he was very helpful and answered all of my questions
I had Great service, it exceeded my expectations. She was very responsive when I reached out for an eta on when my car would be finished.
I was treated the very best !!! You are really caring for us! Thank you very much! Did you get new help? You went from ok to awesome!!!!!!
After a recommendation from a friend we decided to drive from Irvine and give Ontario a shot. I am so happy we did! Jason and team were amazing and I drove away in a car I love! The service, attentiveness, and professionalism were top notch!
Christian Lopez and his supervisor Nichole, were helpful and provided excellent customer service to me. I did not understand how or why I was and am experiencing the car repairs that I am incurring. Nichole took time to explain how, why, and provided helpful solutions to my problems BY identifying repairs that are needed in an order based on severity.
I depend on the service advisors and dealership repair. The few, very few times that I have had my vehicle repaired at a repair shop, I end up at an authorized Mercedes repair shop to have my car repairs CORRECTLY.

On 3/23/21 Kyle was the man. I did not say a word or show any negative body language whatsoever when my S550 was returned to me. Kyle looked at it, and was NOT happy (and that's to say the least). He immediately approached the attendant who was still seated in my vehicle. I don't know what Kyle said to them, but I discerned he discreetly "schooled" the attendant on an obvious problem. A problem which the attendant should have noticed, and should have taken care of before bringing me my vehicle. Kyle apologized to me. He assured ...
Best service, did everything in a timely manner! Excellent service!
The entire service department employees were courteous and efficient. My thanks particularly to Robert Tabor. He was polite, efficient and excellent in communication with my car service needs.
It was a great experience. Jason helped me to find a great car at a great price. Debbra, Derek, and Bernard helped me through the day of purchase, with great support and service. Thank you!
I purchased my 2021 E450 this weekend, and had a great experience. The dealership was very professional, and Jason Cai was a pleasure to work with. They were very prompt and respectful of our time. We reached a great deal without spending hours on negotiations, and were able to focus on the car, versus the numbers. We went in with our own financing, and they never pressured us to use theirs, except as an option contract. However, since the finance manager got us an even better rate, we did go with theirs! We were very torn between this car and another, ...
Eli El Ray and Ali Ferdaous were amazing sales professionals. I bought the GLS from them. It was a pretty fast process. Also the finance manager Bernard Azar was great, professional and quick. Both Ali and Eli called is the second day to make sure all was good. My wife loves her new car
The service representative Ron Broussard was amazing. So kind and genuine he really made me feel comfortable. I was definitely happy with his representation of this Dealership, and their service they provided! Thanks again Ron!
Very pleased with the exceptional service provided by my advisor Mr. Phil Gibson. Every visit has been handled very professionally. Everyone was helpful and polite, right dow to the water.
My experience is always good. My service rep. Is Mike Doehla he is very knowledgeable of my cars. He has great communication skill to help the customer understand the repairs that are needed to keep your cars running at an optimum level.
We were returning home to Oakland driving from Palm Springs when my engine light came on. This never happens on this car. Due to the long road ahead we quickly looked up the nearest Mercedes Benz dealership with a service center. Christian Lopez and all of the staff were super helpful and were able to squeeze us in on a Saturday afternoon. The problem definitely would have impacted the ride home -- so glad we stopped here. They understood our situation and were super nice and helpful. I highly recommend this location. They finished a bit earlier than expected, many ...
This was my first time leasing a car and our sales person was rest at explaining everything.
I was deciding between a Mercedes and a Volvo and I can honestly say it was because of our sales
Person Cameron Zerpoli that made me choose Mercedes.
Service Adviser Phil Gipson, was excellent. He was very friendly and easy to talk to. He listened to what I ahd to say about the problems I was having with my car and told me after the car had been examined by his mechanic he would call me with he recommendations. He was prompt in calling me and explained everything that needed to be repaired.
