I had a great experience at M&M Alternators & Batteries! The service was fast, friendly, and affordable, and they had some of the best deals I’ve found. Leo was especially helpful and made the whole process quick and easy. He was professional, knowledgeable, and made sure I was taken care of without trying to pressure me into anything. If you’re looking for a place with great prices, fast service, and good customer service, I definitely recommend M&M. Ask for Leo! He’s awesome

Dree Dree Martinez

Purchased a Groupon for just an oil change. Service was excellent. I called to make an appointment. Was in and out in 40 minutes even though I was quoted 1 hr. Got some great service recommendations and pictures to show me. No pushy sales but great explanation. I’ll for sure be coming back.

Enrique Alcantar

Great service. They were fast, helpful and a good price. It is the cleanest nicest auto shop I have ever seen. I felt very comfortable there.

Sandra Glover

Leo is an angel on earth he helped me so quick and I appreciate him so much I definitely recommend here, they also have great reasonable prices. Thank you again

Domonique Stuckey

“I’m writing a new review because of the fantastic service I received today at M & M Alternators & Batteries. I came in to take advantage of their $39.99 oil change special, and the whole experience was top-notch. Daniel was a huge help; he walked me through everything, went over my vehicle’s current condition, and gave me some great, honest recommendations. It’s hard to find thorough and friendly service like this, but Daniel absolutely delivered. Five stars!”

A Munoz

We brought our vehicles here through the Clean Air Rebate Program, and the experience was excellent from start to finish. The team was professional, honest, and provided outstanding customer service throughout the entire process. Thanks to their quality work, both of our vehicles now have wonderfully working A/C systems, which has made a huge difference in enduring the Redlands heat! We truly appreciate their expertise and dedication to customer satisfaction. Highly recommend M&M Alternators

Jordan Basurto

I came in for an oil change and had a great experience Sophia and Danny were honest, friendly, and incredibly helpful. They took the time to explain everything and never tried to upsell me or take advantage of me, which I really appreciated. As a woman, it can sometimes be intimidating going to an auto shop, but they treated me with respect and made me feel comfortable the entire time. Excellent customer service—I highly recommend them!

Nat

I was there Monday and had a great experience! I had gone in for an oil change and they helped with a few more things they found. Daniel helped me out and made the whole process easy and understandable. It’s good when the place is clean and has a handsome man like Daniel greeting and helping you in the front! Definitely recommend M&M very thankful for the help and services really honest people will be recommending them to everyone!

Michelle Olivas

This was my first time visiting this shop, and I can honestly say it exceeded my expectations. I had heard great things about them from friends and family, so when my car’s AC stopped working, I decided to give them a try. From the moment I arrived, I was impressed by how friendly, professional, and welcoming the entire staff was. Everyone I spoke with was approachable, knowledgeable, and willing to answer all of my questions without making me feel rushed. One thing I really appreciated was that

esmeralda rojas

Five stars all the way! I walked into this shop needing a quick battery replacement for my 2024 Chevy Malibu, and I couldn’t have had a better experience. Alex took care of me right away. He was super friendly, very knowledgeable, and took the time to answer all my questions. It’s hard to find auto shops that offer this level of genuine customer service. I’ll definitely be coming back here for any future battery or alternator needs!

Sean Christian

I appreciate Leo for helping me today he went out his way to help me figure out why I’ve been constantly having to replace my batter twice a year. He also replaced the part that was needed. Helped me save money tbh. Highly recommended this place. Quick service

Shatianna Ragland

Leo is awesome! His shop fixed our AC, and it now works like new. I’ve taken three of our vehicles here—our Nissan Armada, Honda Crosstour, and Dodge Caravan—and the service is always incredibly fast. I have nothing but positive things to say about Leo and his team. I truly appreciate his professionalism and positive personality. It is hard to find a mechanic shop you can trust, but this is definitely the place!

Javier Larios

Awesome service! Leo is great and upfront about cost. Fair price and competitive. Will be coming back for future services and oil changes! Thanks guys!

Jeff Alva

For your A/C needs Go here!! I was quoted over 400 elsewhere. These guys are friendly right off the bat and are totally honest about what needs to be done to your A/C. When other places recommended a flush and over 400 in total. M&M looked at it and said it’s your service valves, cabin filter and a little recharge. I Paid just over $100. Thank you again and you gained a customer for life!

Pedro Zamora

This place is great. Ive had my car serviced by them twice and both times, the car was fixed within the day. The price was below what I had expected to pay and they have great communication, they kept me updated about my car and their recommendations.

justine o.

Shoutout to the team! We came in to get a second opinion on my car A/C and they helped me out with just relaxing my mind and explaining everything that they did. I recently bought my car off the lot and I would take it to the dealership and they would say my car is fine but never explain what they did but still having the same issue. Thank you sooo much! Their prices are affordable and they also allow the price you paid be added to any other service you might get with them!!! So cool! I would to

Priscila Portillo

I would give this place 5 stars because of the work and price. My ac compressor went out and they charged me a great price with a great warranty! I had to drop off my car to get the work done and they promised me I would get it back same day! which is very accommodating. The only thing I wish they would have done better is an update on my car and when it was ready to pick up. I had to call in. Other than that I would recommend getting your car fixed here no doubt and will be coming back for futu

Ashley Perez

I came in as a walk in and leo treated me like I was a 10 year repeat customer. My oil change didn’t take to long. The prices was excellent also. Prices was good compared to others.

Anthony Fowlkes Sr

Repairs done in a timely manner, comfortable waiting area and good pricing. Brandon was helpful and knowledgeable. Would recommend your garage to friends and family.

Isaac Diaz

Brandon helped me today! I made an appointment but he was able to take my car in a little bit early. He was so polite and professional. Everytime I come, the staff is so nice! It is easy to make an appointment on the phone or on the website! They send great deals all the time! I’m so grateful for their care!!

Judy

I came in because I had a flat tire and Jake assessed the repair. Took a picture of it and showed it to me and advised me what I should do and what would be the best solution so I purchased a new tire. They got it up in no time I went out of the go pick it up at another location. Very happy with the service Jacob Rico, and the team.

Jim Gray

This place is awesome. LOU is amazing so sweet, and helpful, great personality and professional. This was my first time going there. I have a Kia Optima and called Kia service in San berdo and they told me to fix my air that was not blower off and on, to drop my car off and they would have it for a minimum of 3 days. My car only has 22,000. Miles on it and this shouldn’t be happening. So I thought I would give these guys a try. They are fair priced and fixed it within a few hours. Great wor

Lisa Smith

I had an outstanding experience at this shop, and I cannot recommend Daniel enough! He did an amazing job helping me with my car. He was incredibly efficient, managed to get so much work done in a timely manner, and provided top-tier service throughout the entire process. It is always a pleasure coming here knowing that my vehicle is in such capable hands. If you need quality work done, ask for Daniel—he’s the best!

Best customer service hands down, they’re efficient and affordable. I’ve been bringing my vehicles here for a few years now and every time they exceed my expectations! Their professional and friendly staff will take care of you. 10/10 recommend!

Jose Morales

I needed a battery asap on a small Budget and M&M Alternators and Batteries was there to save the day!! The service was fast and efficient!! And they replaced it for me (for a small fee). I purchased a used battery and it came with a 3 month warranty! I am so thankful for M&M.

Maggy Salgado

Benjamin Amezcua

My bf came across an ad on Facebook for M&M as he was super happy with his experience. Meanwhile, I had a feeling my current mechanic was NOT being fair on an AC repair for my car. Reached out to Leo at M&M and he had my business that very moment & ofc their waiting room with AC. 🥶 🤣 Not only was his pricing cheaper, I was so impressed with their customer service (Diana), speed, and organization of a text messaging portal I had never heard of! All-around M&M is UNBEATAB

Teresa Silvasomsak

Customer was amazing. Came in for an oil leak and was able to tell me what was wrong. Leo was very helpful and keep me updated and made sure I got the best care. Highly recommend they are fast friends and good customers service

Marlena Artalejo

I went in for the first time today after finding an amazing deal on Groupon. I made an appointment for an oil change for 10:00 and figured I’d wait. It took approximately 2 hours for the oil change, but Emerson gave me a free tire rotation! They have amazing deals for oil changes with a $19.99 a month membership! It includes way more than an oil change, so the price is well worth it, especially if you drive alot! They have amazing prices on used batteries as well. Great service, amazing deals an

Veronica Crafton

I had a great experience. The M&M team was kind amd acknowledged. No extra surprise charges. Definitely, I will use their services again.

1,200 for AC Compressor isn’t bad. Brought my car in and everything was straight forward and to the point. Was recommended to come here by a family member and was worth it, glad to know I’ll be surviving this years California heat with these mechanics backing me up. Here is a picture I took of my car that has been saved by these guys

llonndo

My first time getting my oil changed and they remembered to change the sticker on my car and to break indicator. I have been there several times for my for battery to check my battery they are always awesome

Darlene Taylor

Shoutout to Tyler! I’ve known him for years, and I can honestly say he’s one of the most trustworthy mechanics I’ve ever worked with. He truly puts his customers first, explains what’s going on with your car clearly, and never tries to upsell you or push unnecessary repairs. It’s rare to find someone that honest and dependable these days. I’m really thankful for his service and I highly recommend him to anyone looking for a mechanic they can actually trust.

Filmon Kifle

Tyler, from Redlands was awesome he was very friendly and excellent with customers service. Brought my old 2007 to get my air conditioning fixed and with options they had available made this expenses affordable. Yahoo I’m ready for the summer. Thank you M&M

I’ve had great experiences coming to this battery shop and have never had any issues. The first time I came in, I purchased a used battery that lasted a long time. I recently returned and bought a brand-new battery at a great price. I even got a battery for my mother here, and it’s still running perfectly. The staff is very nice and helpful. Emerson provided excellent customer service and helped me choose the best option for my car with absolutely no pressure. I highly recommend this shop—

Afjal Husein

Fabulous service!! Had my rear brakes serviced. New pads and new rotors installed on a Ford F 150 4wd. They showed me the worn parts and shared with me some other areas of concern, that we agreed could be deferred without causing a safety issue. No pressure to repair immediately The work was performed professionally and In a timely manner. The price was very affordable. It cost approx 25 percent less than a recent brake job on my other car at another shop and that job did not include new rotors

Dennis James

M&M is my go to shop to work on on my vehicles. I’m always skeptical of auto shops, but I have built a relationship with this shop. First my Jeep, then my Honda, I got good prices for the work I had done, and I wrench on my veh7, so I know what it should cost, and how long it should it, I just don’t have the time to wrench, so I bring my cars here, and I recommend them to amyowho asks me if I know a mechanic…..

Elizabeth Dean

M&M Battery and Alternator is absolutely amazing! They were fast, friendly, and professional from start to finish. Their prices can’t be beat — I got a brand-new battery for just $180,and the total came to only $200 including installation. The best part? It comes with a lifetime warranty, so I’ll never have to pay for a battery again! The staff, Tyler specifically, made the whole experience quick and easy, and their customer service was outstanding. I’m so happy to have found this pl

marianne milita

10/10 experience. Jesus was the mechanic I dealt with the whole time which was awesome because he was very communicative and honest. I took in my Chevy truck because my brakes were very stiff and essentially not working but that was just the tip of the iceberg berg. As they got started troubleshooting the problem they came across another issue and let me know right away and what my options were, Jesus explained it in a way I could understand and felt comfortable entrusting him with my truck.

Daniel helped me a few months ago when I wanted my 1973 original equipment, Ford Pinto generator rebuilt, and today Chris helped me when I brought in my 1999 Mercedes-Benz W210 Wagon alternator. I had it back in my hands by the end of the day. The price was fair, and the service with these two gentlemen was nothing less than exceptional. I’ve used the Mt.
