I had the pleasure of working with Sergio and Seiko. Both were very easy to work with, patient, and thorough. They made a list and went through all the details of what services were needed and NOT needed with the car. The entire process was very pleasant and I never once felt like they were pressuring me to do other services that weren't needed like some other shops. They also took the time to address a couple of items that weren't part of my to-do list for free. I work nearby so it was great that they were able to drop me off. Then, when the car was going to be in the shop for longer than a day, they provided me with a loaner car for free. read more

Went in to change my starter on my Honda CRV and they did a phenomenal job in doing it efficiently and cost efficient. They were very friendly and courteous and I would definitely go back to do my maintenance on my CRV and Sienna. The main thing that put it at 5 stars was the transparency and the clarity into what they are doing and the cost. Definitely a happy customer! read more

Seiko and his team are great! I was looking for a new place to get my car routinely serviced and I have definitely found it. Here's what I liked: 1) They provide pick up and drop-off service if you live locally so you don't have to just sit and wait! 2) They provide updates on your car and their work and they are able to send pictures of what they're working on and what they might need to work on. There isn't this back-and-forth phone tag that often happens when you bring your car in where they call and wait for the green light to do the work. You can approve or deny any work on your car via the link they send you. Sergio and Seiko were willing to answer any questions I had. I'm not too knowledgeable about cars but I didn't get the sense that they were ever trying to upsell me on a service I didn't need. This is now my go-to car spot and I'd recommend them to any friends who needed their car serviced. Note: I think he specializes in cars within the Toyota family. read more

Seiko is honestly the best mechanic I ever had. His service was great from the moment I made the appointment. What I loves is that he was very informative and personal. He explained that the shop is a bit hard to find but, but he explained clearly how to find the shop so it was no problem at all. He also offered me a ride to a nearby place to wait since it takes a couple hours for service ( I just hung out at the coffee bean nearby) fast forward.. being a young female car owner I usually feel intimidated by mechanics, but Seiko was so nice and explained everything that needed to be fixed (when all I thought I needed was an oil change) He broke it all down by priority of service and price. He also explained that he caters to each specific car by its need, not just "by the looks of this, it's time to fix it that'll be $354" (exaggerated) but you get the idea. I felt very well taken care of, and being new to the city of Duarte I feel like I found my go to mechanic. Thank you thank you thank you! read more

Seiko, Cody and Sergio are the best. They take care of their customers and take time to understand our needs. For sure they will take care of you. read more

Everyone here is fantastic. They check everything over and let you make informed decisions based on their professional recommendations. You feel absolutely safe and confident when driving knowing Seiko's has taken care of your car!! read more

These guys are awesome. Took my Honda Civic to have it checked out. Was advised to have programming software replaced by Honda. Problem was solved with update (by a Honda dealership) to software. No charge by Seiko. Will recommend to my customers with Hybrids.... Keep up the great service!!! read more

There aren't very many service shops that have people who are as honest and reliable as Seiko's Auto Service. Seiko, Cody and Sergio are good people and do a great job servicing my Pilot. Their knowledge is impressive and up to date with ever-changing technology. They take the time to thoroughly explain things so I would understand, which I appreciate. I've never been disappointed with their work. read more

Got my brakes and oil change. Excellent work and it was done on the same day. Knowledgeable team. Professional and outstanding service.

Prior to making the trek to Monrovia, I had taken my Lexus to Mitch's Auto Repair in Pasadena. It was a simple brake job. Change the rotors. Change the brake pads. The brakes squealed and screeched to no end. "Drive the car it a little longer, they need to be broken in," he said. Two months had gone by and there was little to no improvement. I paid a total of six visits to the shop. Time and money lost... Frustrated and at my wit's end, I took the car to Seiko's at the behest of a friend. I had called ahead. While they were expecting me, I surely did not expect that they would repair the car on the spot. Seiko and Cody worked double time to remove the tires and inspect the brakes. Their expert knowledge regarding Japanese vehicles and their specialty tools led them to an immediate diagnosis of the issue. Problem solved. A lot can be said for expertise, experience, efficiency and expediency. My car will be taken no where else from here on out. read more

These guys are absolutely awesome! Customer service and attention to detail is their expertise. They were able to fix a cracked drive shaft on my 2005 Toyota Tacoma which I use as a work truck. Turnaround time was unbelievable and greatly appreciated since I use that vehicle for work! They are straight forward on pricing for repairs and give you a list of maintenance services they would recommend. These guys are top notch and I would definitely recommend anyone who owns a Toyota to bring you vehicle here. Thanks again Seiko! read more

Seiko and Cory are professional, thorough, and good-natured. They take the mystery out of car ownership and care, and empower me to understand my car and it's needs. I live 400 miles away and bring my car to Seiko's when I visit family. So great to find honest mechanics. I have a 15 year old Prius with 175,000 miles on it and they help me keep it running like new! read more

Apparently I was driving with no headlights for who knows how long, and I didn't want to risk another day of nighttime driving without getting it fixed. I contacted several auto repair stores, but Seiko was the only place that was able to accommodate my hours as they're opened until 6PM. When I arrived, Seiko and the other mechanic were very professional and explained not only about the headlights, but the entire check and process of everything else they did around the car. They even topped off my oil and checked/filled up my tire pressure. Time well spent for me and I may start coming here for my regular car services. Thank you Seiko & Team! read more

If you're looking for a mechanic that is knowledgable and trust worthy, look no further. I've been bringing my vehicle to Seiko many times now. Mechanics you can trust is hard to come by these days. Knowing that my car is taken care of without stressing over madness makes the experience comforting. I used to work at a dealer. Wouldn't recommend taking your car to a place where they only see dollar sign over out of warranty vehicles. read more

Seiko's is great. Cody was polite, knowledgeable and explained everything that was going on with my car. It is good to have craftsmen who know their business working on my car. read more

After having my car serviced at Seiko,s Auto Service, I was amazed at how smooth the ride is. The dealer quoted me $8000+ to fix my car and suggested that I trade it in for a new car. My total cost at Seiko's was $3400 and my Lexus runs beautifully. I will be able to keep my car for a few more years. The customer service was outstanding. Seiko updated me often on the status of my repair and recommended some safety repairs that the dealer should have noticed. I will be a regular client at Seiko's for the life of my Lexus. read more

Seiko is awesome! It's nice to find a local mechanic who is extremely passionate and detail-oriented about his work and who takes care of your car like his own. Seiko is also very responsive and prompt with phone calls. I had a problem with my car battery and he was able to answer my questions right away. Way better service than I would have gotten at a car dealership. Thank you Seiko! read more

Good service. Kept in contact through the while procure. Explained in detail. Didn't try to update services. Even told me not to do stuff that wasn't necessary yet. Will be going back. read more

Seiko is probably the most honest and knowledgeable mechanic I have experienced. He never cuts corners and he is very meticulous with his work. He even took the time out of his busy schedule to take a look at my truck. If you want to get your car done right definitely take it here. Honest and great work. read more

My parents and my sister take all their cars here. They've been telling me to take my car here for years and I just stuck with the dealership because I thought it was "safer". I learned that at the dealership, the service provider that I thought was the mechanic is only a salesman and you never know who is actually working on your car. Seriously, google it :( I took my car in to the dealership for an oil change and "world class inspection" just 3 weeks before it overheated. I couldn't even get through to the dealership and got my car towed to Seiko's instead. Turns out the dealership was taking shortcuts and their inspections were not very thorough. There were things on my inspection that passed that definitely should not have but I was still told to replace some things that probably weren't necessary. Who knows how long that has been going on? Anyways, Seiko is very nice, professional and is not pushy about replacing things. He's honest and will also explain what's going on. My family told me it might be a little bit more expensive sometimes to get things fixed here but once it's fixed you won't have an issue with it because they do a very thorough job and it'll save you money in the long run. (Example- We spent so much money on my mom's Camry and always had to take it back to her old mechanic for the same issue. Once they switched over to Seiko's, he fixed it and they haven't had problems with it since.) I'll definitely be taking my car in here from now on! PS. Seiko speaks fluent Japanese so definitely a plus if you have parents/relatives that only speak Japanese! read more

I was referred to this mechanic by a friend of a friend. He is close to my wife's work so she can drop off the car during the week. Seiko (the owner) is great! He was honest and upfront about everything. That's hard to find in the mechanic industry! He was in constant contact the entire time, sending me pictures of the work in progress! I never had to call and ask about my car as he kept me well informed and explained everything to me. If you want honest and affordable mechanic look no further! read more

Seiko is professional, reliable, and has great customer service. After fixing my car, I still had some questions and they were patient in answering me. The price is not the lowest, but their professionalism and attention to detail makes up for it. Would definitely recommend read more

After going there numerous times with my truck for routine maintenance and other major services I've finally decided to give them the review they deserve! Phenomenal customer service every time, the team they have does great work, and very timely and consistent and always impress me every time I pick up my truck. One of the cleanest shops around as well, very organized and well put together read more

Seiko - one of the only few honest techs left in this world! Coming from the automotive industry myself, I know it is extremely difficult to find a private shop that you can trust to work on your car and not get ripped off. Seiko is an ASE Master Certified tech that knows what he is saying and doing. I had a great experience here and I recommend anyone to give them your business. I watched as Seiko worked on my vehicle and I can tell he takes a lot if pride in his work. Honest, helpful, knowledgeable, and gets the job done right!!! Excellent job!!! read more

Seiko's Auto Service - Auto Repair Near Me - Monrovia, California

Seiko is my family's go to auto mechanic. He honest, quick, and reasonably priced for the top quality work he and Cody do. I trust him 1000% more than any Lexus dealer auto shop. read more

Seiko is the real deal! Mechanics like Seiko are extinct. Seiko is super HONEST, THOROUGH, PROFESSIONAL, and TRUSTWORTHY. Prices here are fair and workmanship is excellent. Thank you Seiko! read more

I've always found it a challenge to find a good mechanic. This comes from my lack of knowledge about cars and the horror stories everyone has heard about being taken advantage by unscrupulous techs. For that reason I was thrilled to have met the owner of this new business who is knowledgeable, understanding and offers competitive pricing. I took my Scion XD into his store today and my experience was outstanding. Yes, the business is new. Less than 6 months according to the owner but I see this as a good thing because this means more personal and honest care. Two points to consider (and the reason why I did not give it a 5 of 5 stars): 1. The location is a bit challenging to find but once you know its there it makes complete sense. 2. Seiko only services cars that are foreign makes. (I would love for him to work on my Ford truck). These are minor concerns overall and they pale in comparison to the great find I feel I've made with this car shop. I'll certainly be returning here again and again (well if the car needs it :D) read more

I was referred to Seiko's Auto Service by a couple of friends after getting the runaround from my local repair shop. Upon arriving Seiko was very attentive and was able to diagnose my mechnical issues fairly quickly. It turned out my car was in need of some major repairs, and Seiko was able to resolve them fairly quickly at a very reasonable price. Honesty, Good Customer service, and a skilled professional at his trade... I will no longer bother to head to anywhere else for my car servicing. Seiko is the man to go to! read more

I was referred to Seiko's Auto Service through a friend and now I won't take my car anywhere else! Since I drive a Honda Accord he was perfect! Seiko specializes in Japanese vehicles - especially hybrid vehicles! I used to take my car to another mechanic but it just seemed like the job was never done. Once one issue was fixed - another problem would arise soon after. I always felt like my car wasn't reliable - and somehow would breakdown on me any minute or wouldn't start etc. After taking my car to Seiko's just for a standard oil change, I was truly impressed! He had great customer service, fast turn around time, and even took the time to educate me on the differences in oil quality and showed me the differences in air filters! He also took the time to run a full diagnostic and showed me what problems were present or could arise in the future. He was honest about his recommendations, never pressured me into extra services, and helped me prioritize which repairs needed to be done first and which ones could wait. It was this type of quality service that I felt confident having my timing belt changed a few months later. That was a major preventative service repair that needed to be done but there's no one else I'd trust to touch my car! My car was ready to be picked up the next day and it has been running great ever since! My boyfriend drives a Honda CRV and he also had his timing belt changed at Seiko's. If you want a truly different type of mechanic, one that is passionate about Japanese vehicles, will educate you in the process and be HONEST? Then look no further! It's a great feeling to feel safe and confident every time I drive my Honda - Thanks Seiko! read more

I don't know much about cars, and I don't trust mechanics and car shops, but Seiko has definitely changed that. I've taken my Subaru Forester into to Seiko 2 times and I've been impressed with their communication and transparency all times. read more

Very honest. Looked at my car, detailed the issues. Told me the issues should be covered by my warranty and let me go to dealership. Absolutely a delight. Will go back to them for sure! read more

I have been going to Seiko's for our two cars for two years now and service has always been stellar. Thorough, honest, accommodating, knowledgeable, Seiko and Cody are exactly what I expect from my local mechanic. It might be slightly pricier than other shops, but you get what you pay for and the difference is definitely worth it! read more

I recently took my Honda Civic to Seiko for the 40,000 mile inspection. Everything went smoothly. He kept me well informed throughout the process of what I needed and didn't need. Unlike other car places, Seiko isn't working off commission so he won't try to sell you anything you don't need. The most important thing about going to a mechanic is trust. He fixed everything promptly and my car was ready in no time. My car is now running super smooth. I have no complaints. I recommend Seiko's Auto Service to anyone/everyone. My friends have also gone to Seiko and all were highly satisfied. Note: Seiko does high quality work and uses factory parts (the parts each car is built with.) They are not cheap but coming here is worth every penny! read more

Seiko is great! Brought my older Prius in last week and he did a very thorough job at diagnosing the problems and getting my car working again! Extremely knowledgable and very personable. Great service and very honest. Definitely recommend and will be back. read more

Thank You Seiko & Cody for helping me keep my wife on the road and off my back!! See you again soon read more

I brought in my Toyota for an oil change and general check up for the first time to Seiko's shop. I was immediately greeted by him. Super nice guy and explained everything. I needed to find a closer, trusty mechanic. This is going to be my new go to spot for my Toyota. He did a wonderful job of explaining everything before authorizing any service. He also helped me resolve with a minor issue with the car. It was a very thorough inspection, and he even went to the trouble of cleaning my dirty windshield! This spot is a hidden gem, really wish I found him sooner. Also, he can read upside-down. Thank you sir! read more

I definitely recommend these guys to anyone with a Japanese auto. They are thorough and I truly trust them with my car. Thus far, they have solved every problem I have brought to them.... they really know what they're doing. They take the time to thoroughly explain what my car needs in terms that I can understand. Yes, only what my car NEEDS because they understand I drive an economy car, not a Tesla. The service is friendly and the report is fantastic for record-keeping read more

Finding an excellent car repair shop -- and by "excellent" I mean courteous, skilled, prompt, honest, reasonably priced -- is like finding a needle in haystack. Well, I found the needle. I won't take my Subaru any place but Seiko's from now on. If you want service done right and on time, Seiko's Auto Service is the only place to go. read more

Decided our faithful Accord deserved to see someone who knows what he's doing, and Seiko sure does. He is helping us figure out the best way to make our car go as far as it can! Appreciate his photos and communication regarding everything that needs to be worked on. read more

am extremely happy to know that this young man has come this far. i met Seiko when he first started out as an apprentice. i remember saying to him strive for the mechanics license. sure enough he did and went on to have his own shop. good on you seiko. heck ,he overhauled my 1948 willy jeep in his off time! i am greatful for that .my wife and i attended his beautiful wedding which was held on the beach. we were introduced to his two lovely kids when they were born. a beautiful family. seiko showed his work ethics long before having a shop . and i am sure he will carry this until retirement. a caring man in his endeavors, should go far. good luck seiko -san and instill in your helper to strive for bigger and better things . such as becoming a master mechanic such as you. two master mechanics in one shop would be awesome . your friends , pam and ramos . read more
