I bought a rebuilt alternator from M & M Alternators for only 55 bucks and it came with a 2 year warranty! The customer service is great and the prices are low. Stop over paying for car parts and check them out today!

Junk Battery

I bought a battery from these guys on March 5th for my VW Passat and it went completely dead in 20 days! I was so mad when this happened and when i called them about it I was told that would happen if I didn't run or use the car but yet I was using every day since I bought the darn thing. The nerve of that smartass! Every other expensive mechanic I called told me that if the battery died out in less than 30days then these people sold me the wrong battery for my vehicle or they just never fully charged it! Everyone look out for deception and make sure what your paying for is the actual product/item you need and will work for more than 30days because its a hassle to go back and forth so much and can get irritating.


i would like to say this is one of the best alternator places i been too thats not expensive like the autozone n napa ..had my alternator rebuild for $50 with a 2 year warranty when autozone offer it at $139.99 and 1 warranty ..thanks guys




definetly never coming back EVER!!!!! got my RV alternator rebuilt here it lasted less than a month WTF!! for trying to save money it costed me a lot more!!! i had to take it to the dealer. next time I'm going to pay attention to the reviews instead of risking it!!! the cheapest cost more.




this place really sucks bad service,bad quality and they dont give the warranty they say ,have my alternator rebuild twice they told me it was an electrical problem took it to another place in Fontana got it fix IT WAS THE ALTERNATOR , I would NOT recomend this place EVER!!!!.

Hi ,

Im the owner of M&M Alternators and i apologize to any customer that was treated bad at our shop . M&M has been around the Inland Empire for more than 30+ years we strive to have the best customer service and best price in the area. We deal with more than 50+ customers day and as any business we have weakness and we have work in improve over time and our sales numbers have shown that . Like any business we have our good loyal customers and our bad but they get treat the same respect as everyone that walk in but at the same time theres policy in place that my workers must respect an that case customers get mad and make a bad review .

i apologize for the way you say you were treat at our shop and i assure thats not the way we treat our customers and I'm sorry if you were. You also mention that you got a alternator for $100 at M&M but i can guarantee that we have no such price for any alternator even for 2007 ford edge alternator that we repair for only $75 with a 2 year warranty and our parts (alternators,starters,axles) price range is $40-60 . But if your mis treated please contact me at the shop # (909)888-0907

*ASEMASTER TECH you mention that you waste 30 mins creating a account( ON AUTOMD.COM) for the website to post a review but you had plenty of time to post a similar review for about 5 different website all this sounds like a personal or business competion review. (

*Our batteries are Semi-New and no we do not clean and put them on the shelf we have our company that supplies us with the batteries new/semi-new

* Our work is guarantee for 2 years (batteries 6 months ) . When your local Auto Parts store don't have what you need guess who they call.

Any customer that feels that was treated bad please let us know and we will take care of the problem



Bad business

Called for starter they said they had it on stock ,I get their and they said they would rebuild it . I waited 3 hours came back still not done . They have been in business cause once they have your part you are at their mercy. Anyone can get a customer when you advertise but they will not get a return visit. These people are crooks they are not going to get my business again . Now I'm still at their mercy going on 4 hours can't get my starter back or my money.



I bought a starter from them a...

I bought a starter from them a few days ago, it caught fire!!! So I go back and they said Oh its your car, then they said it was my install error. Theres 2 wires and they cant be switched because one is a 16G and the other a 4G! So they told me they would replace it once, I put it back on my car, and it started to smoke after cranking it twice! I Went to autozone, bought a cheap reman one, and it fit and worked PERFECT! Screw you guys!



DO NOT come here. They sell b...

DO NOT come here. They sell bad alternates and then blame you for alternates not working. I'm ASE master tech and these idiots kept saying its my car which it was not. Do NOT honor their warranty. Got a bad alternator 3 times. I had to unistall and install 3 times! What a waste of 10 hours. Alternate is JUNK. Tested at Napa and output is 11 volts when it should be 13-15volts. Finally I got one from Napa. Guess what? Car was fixed. I wasted 10 hrs of my time NOT Including driving time and gas money! Also lost 100$ on the alternator I bought ONLY 2 weeks ago! Stay away from these.

DONT GIVE YOUR MONEY TO THESE CROOKS! they DONT rebuild ANYTHING, just clean it up, swap out bad part with OLD USED garbage and sell it to you again. THAT IS NOT CALL REBUILDING!!! ITS CALLED A SCAM, LIE, FRAUD!
