Miguel Moncada
It took a few weeks to sort my issues out. But Chuck came through and I am still driving ing my 2019 Chevy Crew Cab. Thanks again Chuck!
Robert Curtis
Great team dynamic, very easy going and friendly staff. And quick turn around time as well, I got my vehicle back within a week which is fast in my opinion.
G Kai
Brought in my VW Golf TDI in twice and was happily surprised with their service and honesty with the work. Chuck is very knowledgeable and takes the time to explain the cause not the symptom of the issue. I was also impressed with how well run and organized the shop is, behind great shops theres a Tammy.

We are so grateful to have found Chuck and Tammy. We have San original Chevy that needed some adjustments for a coast to coast trip and they came through. They were able to find the parts and completed the job on a crazy timeframe but also work with our budget. We are foverver grateful, especially with everything personal that happened, they still came through. It is a blessing to find good people that will keep it straight and honest. If you need your car service look no further.

Evelyn Aguilar
Amazing service and great communication. Highly recommend!
Daniel Shimoda
Everything works great on my vehicle now! They do a thorough job diagnosing the problem and get you back on the road in no time! All of the employees are very friendly and considerate, Tammy even gave me a ride home so I could leave my car there and on another visit, so did Melissa. They kept in touch with me and let me know what was going on with all the repairs. AG has a holistic approach to checking on and maintaining your car! Thank you!
Angela Guida
Been doing the "happy dance" in my mind cos my truck works again! After "Muffler Nayarit" & his little cronie did a number on ma vehicle, Mr Chuck (to me) bent backwards to get it fixed! Tammy was great cos she made me feel like a friend & not just a customer. I am grateful! Praise God ma truck runs and sounds great!

Chuck did a great job and he really knows his stuff. There is a difference with someone tinkering with your vehicle and a true mechanic and Chuck is a true mechanic, and Tammy is just the best!!! I definitely recommend A.G. to anyone!!!
Dave Smullen
Chuck and Tammy were excellent during this entire process. Long story short, came in thinking my catalytic converter was stolen from my car and they diagnosed that my car’s exhaust pipe broke off. Chuck managed to fix my exhaust pipe and it’s been running amazing since I visited AGAD. They also gave me a great price and I would absolutely recommend them to anyone. The old saying “A good mechanic is super valuable” comes to mind with Chuck and Tammy!
Gene Arnold
I brought in My Scatpack with what I assumed was differential problem, not only did the owner confirm it he showed me the problem first hand. Never felt like I was being scammed for more money just hard working and honest men. Even the owners wife and dog are super cool I definitely ONLY recommend coming here these guys know there stuff and won’t try to get you for more money
Jacob S
Chuck and Tammy are wonderful! As a woman, it’s great to find a mechanic shop who’s honest, reliable, and not looking at you as a quick money grab. It’s rare to find a mechanic you trust, but AG is truly a gem!! Highly recommend. Big bonus that they are believers of Christ!!
Avianna Velez
Melissa, Tammy and Chuck are great! They diagnose my vehicle accurately, it was not an easy diagnose, it involved electrical, computer and mechanical issues! The AG team are accurate, helpful and honest. I recommend anyone to use their services!
Manuel Gallur

CHIBUEZE JBI
Excellent services!! Came here to get my axel replaced they were able to fix it so quick and for such a great price. Tammy and Chuck are soooo incredibly nice. I been having issues with my keys and when I picked up my car Chuck offered to look into the key problem for me, I didn't even ask or bring it up! He stayed after closing time to help look into the issue, sooo kind. I will be a regular here now!
Chani Thammasan
Chuck and Tammy are awesome! Thank you for the wonderful service!
veronica davis
If you're in this area use these guys. Their quote is the price. If anything comes up they are quick to reach out explain situation and price change before moving forward. Excellent service and fair pricing. I recommend this place . They will not try sell you anything that does not need to be repaired. I would recommend this place to car novices and experts. All around Great job. Thank you!
Phillip Pucciarello
Chuck and team are straightforward and trustworthy. They were able to fix a problem with my car within hours that other garages said would take 2 weeks. Plus, Tammy is a joy.
Kristen Franey
This place is one of the best shops I've been to. The owner CHUCK is not only a nice guy but honest. This is the place to bring your car. You always hear about dishonest people who work on your cars or trucks. These guys are one of the most honest I've ever met. This shop is clean, honest and is in a nice area for the family to wait if you need to. So I no a lot of you guys want to be in a safe area. Well this is the spot when you go let Chuck know I sent you and good luck and safe driving.
Henry Hernandez Jr.
Honest, hard-working people! I am happy to have finally found someone I can trust with all my auto needs.
Rocky Andrea
We haven?t had a mechanic in several years, and I am glad we were recommended here. The staff is extremely professional, very understanding of the customers needs and their price is reasonable due to their specialized KNOWLEDGE. Thank you CHUCK for the incredible service and honesty and TAMMY for your 5star customer service. You have earn our business and new customer.
Adan Martinez (2789adanmartinez)
Very nice people. Gave good advice. And taught me some things about the maintenance of my car. I'd go to them for a repair in the future.
Adre Rivera
They were quick and responsive, went the extra mile on the repairs, got everything directly from the dealer, car looks great. Also they're a mom and pop so they have great customer service, are trustworthy and dependable.
Dan Jacobs
Thank you Chuck for your help. Needed a water pump for an F150 Chuck took care of me in 3 days and in this time it is hard to find parts but he was able to. He even took me behind to see what parts were replaced and showed me before he even brought it down the lift. Keep up the great work. Did I mention the competitive prices.
Rodri Topez
This place is fantastic. I'd just purchased a used car, that seemed to be in good condition. But after having the car for only 6 days, I was driving on 118, & suddenly the muffler/exhaust came loose & started dragging underneath the car! I know very little about cars. (I couldn't even name the part that had fallen out until someone else told me!) I'm also a rather petite female, so I'm very aware of what an easy target I appear to be, whenever I walk into a repair shop. Its easy to bs or convince someone like me, who's relatively ignorant about the internal workings of their vehicle, to pay for unnecessary or over priced parts, repairs, etc. So it's always a headache whenever I've had to bring a car in for repairs. However, this time was surprisingly different. I called around to several mechanics & repair shops, & AG Automotive was not only the first to get back to me, but they were very friendly, & able to fit me in same day. When I got to the shop, Tammy greeted me right away, & instantly made me feel comfortable. She got all of my info, & showed me where I could hang out & wait, until the mechanic was able to look at my car. (They have a nice, air conditioned waiting room, with TV, water, etc.) After they lifted my car, Chuck, the mechanic, came & asked me to come look underneath. He explained everything to me in terms that even I could understand. He said the car had likely been in a place with saltwater or snow, as the underside of car was very rusted. Because of how rusted the exhaust was, it had become almost brittle in the area that broke. And since the hanger/bracket, that usually sits underneath the area to hold things in place, was missing, when it broke, it fell & was being dragged underneath the car. Chuck gave me 2 options. He told me I could replace it, or for a lower price, he could weld it back in place & create/attach a new hanger, that would be a temporary fix, but should last long enough, until I am able to do the replacement. I ended up going with the 2nd option for now. I thought I'd probably have to leave the car overnight, as it was late afternoon by then. But Chuck said if I was willing to wait, he may be able to get it done that evening. So I decided to stick around, & I am so happy I did, because he was able to get it done that day. (He even stayed late, until almost 10:00p.m. to finish it for me!) The entire experience was wonderful. From the time I arrived there, until the time I drove away, I was made to feel welcome & comfortable. Every person I interacted with here, was polite, helpful & respectful, & seemed genuinely sympathetic to my situation. They were fast, their pricing was very reasonable, & I never once felt like they were trying to take advantage or capitalize on the fact that I know so little about cars. It was awesome. I've always wanted a regular mechanic, who I can trust, & bring my car to when things like this happen. And I believe I have found that in Chuck. I hope to replace the exhaust in the next couple weeks, & I will most definitely be returning to AG Automotive to have the work done! (**Note: For anyone who is a dog lover, like myself, there was also a super handsome, very sweet German Shepard named Lobos there. Who kept me company in the waiting room, while they took care of my car!)
Bre Lee
I did have a problem with the transmission of my 2013 Nissan Murano and another shop troubleshoot the problem and I was told I needed a new transmission, the price was $4,600 plus tax. I then took the car to A. G. Automotive & Diagnosis at 6824 Aura Ave, Reseda, CA 91335 and Chuck fixed the vehicle at a fraction of the price because the vehicle did not need a new transmission. Chuck thank you very much for all of your help and the way you professionally took care of my car and the great communication. Once again thank you very much.
Arnaldo Sanchez
We brought our Mazda CX-5 in for an AC check, just a week after our Ford Fusion which needed numerous hose replacements. We've been using A.G. for a handful of years now for the Fusion, while the Mazda was serviced by the dealer until the warranty just recently expired. My Fusion was at A.G. for about a week which was a little bit longer than expected. But I realized that parts and shipping can have delays due to all the supply chain issues going on right now. And it helped in finding cheaper parts as they were able to shop around, which lowered my charge from the original quote. So, a week later, we decided to bring our Mazda in, basically without any appointment. The dealer wanted an insane amount of money to refresh the AC. But A.G. checked and repaired our AC issue and got it in and out in the same day. I think they did it so quick as a quiet courtesy for the delay with the Fusion, which, in my opinion, shows great customer service. We will continue using A.G. for all our auto repairs, as well as recommend them to our friends and family. Chuck is a cool, up front guy and the two women who handle the administrative work and the customers, Amber and Tammy, are very friendly and courteous.

Tammy and Amber were very helpful and nice, I think they both took an hour each to explain stuff to me. Not the cheapest shop ,but it's worth it in LA, I'll never take my car to a cheap shop to be lied to again. I would recommend anyone to come here if you care about your car.
Rease Boyd
Amber is such a great addition to the team and is so welcoming! It was also cool hearing how she was a customer and is now a part of the team. She really listened and understood my financial limits during this visit and helped with no judgement.
Alexander Phaphol
My regular mechanic has been really busy lately, and My daughter brings her Prius to A.G. Automotive, so I decided to try them out, and I was not disappointed. Chuck was very professional, and honest. He did fix the problem at hand, but did say he needed a few days to find the actual deep down cause of the problem so we will bring the car back very soon. He got the car back on the road, and I felt very at ease talking to him. He is very down to earth, and to the point. He is a mechanic you can send your kids or wife to and not worry about getting gouged or sold services that are not needed. Now granted they are a bit short handed right now, but they will get the job done. I feel like I have found a new mechanic, Also Thank you to Amber who answered the phone and got me in.
Michael Reynolds
Excellent shop and service. They stayed open late just for me to pick up my car!
WILL Anderson
All around amazing shop!! Some of the nicest and most up front people I've ever met. Aside from excellent customer service, there's no one I would trust more with my car. They got me in quickly and not only fixed my electrical issues, but made sure everything else on the car looked good. They even gave me a heads up on what I will be having to replace next! This shop is a rarity and will forever be my go to.
Trinity Rose
These guys know there cars got a lot done for a very reasonable price I have zero complaints car runs great now!
Ron Arouas
Chuck was great and he's a wealth of knowledge. AG was highly recommended by my local shop for a transmission service on my Ram 3500. He walked me through the things he looks for and the steps that he takes to do the job right. Doesn't hurt that their price was very competitive too.
Jack Sandoz
Awesome. Mechanics and Melissa is awesome too!
Amanda Suechting
Wheel bearing...how could one part cause so much noise, my ears were ringing. A.G Automotive found the issue quickly and charged a fair price. I am happy to have found them. My Focus ST is happy too.
Ray M
Awesome service with great care. I was treated with the utmost respect and care
Richard Watters
Came in to get oil changes for both mine and my wife?s car and had an electrical problem looked at on my wife?s car! They got us in early, got my car out fast and took care of all of the problems on my wife?s car by the next day! All in all they were great at AG auto ! Plus they recommended a great smog check guy !
Belvis DeVille
The shop was very accommodating and got me in for the afternoon wheel alignment as a walk-in customer. Prices were reasonable and no nickle and diming me on service. What they quoted on the verbal estimate was honored and their follow-up after care was very impressive. The owner actually reads the reviews and was very responsive to my minor concern regarding the alignment printout. He immediately replied with apologizing for not having that attached to my receipt and quickly sent me my copy they had on record. He also awarded me a FREE oil change for my concern. I will definitely return for care at this shop.
FRED BICOY
Great guy, great CS and most importantly very reliable.
Ivaan Narvaez
These guys really go out of there way to help you. Only been there twice and they've already gone above and beyond the call on multiple occasions. You can't go wrong. Talk to Chuck
