MAK's ECM RebuildersReviews of ecmrebuilders.com

I was lied to for 3 weeks about my order for a new ECM. I was told that it was in the building phase, then I was told it was in testing and would be shipping the following Monday. On Wednesday I called looking for tracking information and I was told that they don't have any of these ECM's and they don't know when they can fill my order.

Sent them a Jeep BCM with a bad wiper relay, and got it back with a bad wiper relay. I dont believe they did anything to my unit and charged me 200.00. Beware.

This company is a total scam! Their offshore customer service is absolutely useless. Ordered a PCM for a customers car on May 7, was charged instantly but here we are on the 13th with no part, no delivery date and no phone call returns. Disputed charge with bank because trying to get someone on the phone is impossible. I reordered from NPC 2 1-866-326-4227, talked to a person and will have the PCM Friday. Will never use MAKS again and I strongly suggest if you are reading this that you don't either. Order number was E-71499 2014 Ford Focus

This place is a scam do not use - they still have a fraudulent review with my name on their site as a verified customer even though I got a refund due to no services provided. I ordered on 02-25-2026 and was told they had a PCM for me in stock with 2-3 day shipping turn around. A week later they told me it wasn't in stock, but they had a smashed one they were gonna fix to send me. Why would I want a smashed one and how would they expect it to work?! At the time of ordering I left a 4 star review because customer service was easy to reach and the site was easy to navigate and would update to 5 star if everything was received in a timely manner and worked. They edited the second half of my review and posted as a 5 star review - total fraud. When I called them out and let them know I notified my bank they are frauds they immediately refunded my money. Total waste of time - they blame trust pilot for the incorrect review....who knows?.

There isnt a low enough rating to give these guys, im still waiting on directions on how they wanna fix ruining my jeeps ecm..... I spent a year chasing ghost problems and almost 5k later I find out its the e.c.m. they have supposedly rebuilt twice! How do u get it wrong twice. Then they say they will call you back....... the last time it took 5 weeks, this time it has been over three weeks and every time you call they act like they are late for getting off the phone with you. Worst service ever..... now im out the money it took to have them "rebuild" it almost 5 k in diagnostics and the another 2k to fix it right. I would not reccomend to anyone who actually wants ut fixed

After 3 failed attempts trying to buy an ECM, they charged me to return the last one. I tried 3 different ecm's all with different failures. After the 3rd one, they said they didn't have anymore and when I decided to get a refund, they charged me $30 to return the last one that failed. The absolute worst experience I've ever had buying online. You guaranteed it to work then charge me to return it when it don't. This is wrong

These humans are cons you send them the money they send you junk then when you try to get it right they just shine you on. Purchased 6/4/25 it is now 7/24/25 no ecm, no money no HONEST ANSWER JUST LIES AND A PROMISE OF A RETURN CALL THAT NEVER HAPPENS. Proceed at your own risks.

Horrible not plug and play was told I will get a full refund and that was a lie too I’m going to dispute with my bank !!!
