As a completely dissatisfied previous customer (sucker)I strongly suggest that if you are purchasing from this company because of their 'Lifetime' warranty, think again.

I had one of their units installed for under a year when it failed while I was on the road in my Travel Camper. It failed in Amarillo Texas (1600 miles from home). I called FS1 and they said that I must ship the failed unit back to them and they could get it shipped back within 3 weeks from when they receive it. I immediately thought that with shipping it would be a month so it was not possible to consider a warranty claim at that time.

I purchased from a different supplier and had a programmed unit installed in my van in three days including shipping.

This company uses this 'Loop hole' to their advantage so make it so inconvenient that you end up giving up. I had to give up their failed unit as a 'Core' so I not longer had the FS1 'Failed' unit.

After returning home I sent them my 'Original' Factory unit which I still had from when it failed and replaced with the FS1 unit while at home. They declined an warranty claim because it was physically not the same one they sold me. I sent them proof of failure (My Amarillo invoice to replace it) however they still would not honor my warranty claim.

You as a prospective buyer have now been warned so take your chances.

They did return the one I sent them as they would not warranty it but claim it the one I sent even though they painted it. I'm not sure that's true. Has anyone that has purchased from FS1 had the ECM painted over and look like a wrecking yard part?

I warned them that I would never give up warning others.

I purchased a ecm on Feb 25th of 2022. March the 20th, all I had gotten was the running around, then I wrote a review, a bad one, all the suddenly, 3 days later got a package with the ecm, doesn't look like that's a good one. And I had gone to my bank to get my money back. Too much hassle, too many lies, let me give a good advice, don't buy from these people, not at all honesty people. They don't respect us the consumers. For what I got from them, they should be shot down. Bad, bad, bad to core, worthless.

Right now, everything comes, I'm just waiting for them to send it to me, but they told me to let me know that they're working on it

2006 Cadillac CTS, I came across these people online, after reviewing on YouTube I knew for sure what I needed to fix my car. I need a module flagship one was the cheapest, I ordered one from them it arrived in great shape. By the time they emailed me and told me my part have been delivered, already had it installed key learning system complete car running fantastic. If I ever never needed one again I highly recommend these people. God bless you and thank you for getting my car running again

They made sure my request was processed in a timely manner and had send me multiple sources for help everytime I requested it definitely would use them again I'm my shop.

Have order from them multiple times in past. This time however the parts was wrong one. Sent back for refund. They keep telling me they are working on the unit, I keep telling them I don't want it I want my refund. This had been going on for three weeks, and multiple phone calls. Today they said they are about to ship the item. What? I can't belive how bad their inhouse communication is. Customer service suffers severely because of this. The person on the phone is either not doing as they say or they simply can't help you out. It is very frustrating.

I ordered a PCM from this company. Once I received the part and installed it, I noticed the part still did not work. I immediately called the company to inform them they had me fill out a form to go over what the vehicle was doing. I have been getting the complete run around with no return calls when asked to speak with management. I still have no working part and now I have to wait to receive a return label to start the process to receive my refund. I would not recommend anyone to use this company ever.

I just installed the ECM plug and play and my car dont turn on. I chat online, call and send email and they only play ping pong with different people. They dont want ear the problem, just send to different employee without ear what is the problem, how they cant help me if they dont want know what is the problem?

I had a problem with my 2007 Chevrolet Silverado. No crank no start and no communication with ECU... they were glad to help and took my vin so they could program a new one. Installed new on and still no communication. Meanwhile found rodents had chewed wires on my neutral safety switch. Fixed wires and still had no communication from ECU... finally had truck towed to shop for repair. Technition called and asked if i had old ECU i say yes. He re-installed old computer and truck works fine... tech said new computer was not programmed... 600 dollars out of my pocket because of lousy work done by Flagship One company offered no re-imbursement

This company's 2 to 7 day delivery times is not accurate. I am on the west coast and I have never received any product in 2 to 7 business days. I have lost sales because of this. I called to make a return because delivery times were not met. I asked them to cover the shipping back to them and I was told if I wanted my money back I would have to pay the shipping. The agent said my situation was buyers remorse. Buyer beware!

I gave these guys another chance. They are worse than before. I ordered a PCM for a 1999 Toyota Camry on 10/12/2022. It is now 11/15/2022 and the excuse I have received 3 times is that the programing department is behind or the programing has failed. I asked if they would cover the expedited shipping since I had to wait so long. I was told no and I would have to pay $85 to get it overnight when it was ready to ship. After 33 days I had to cancel my order. I tried to call this company about my issue and I got hung up on several times and I never got to speak to a human. The only way to contact them is thru the chat. I work for a national parts chain and I buy 10 to 20 PCM's a year but I CANNOT and WILL NOT do anymore business with this company.

I sent a BMW ECU in for repair / replacement. I got all kinds of emails saying all kinds of things, like it was in final testing, it was in shipping, etc, WEEKS BEFORE I got the phone calls - "The techs just started working on your unit. What problem were you having again?" They never fixed it after having it for 6 weeks. I had to send it to another company which fixed it in a few days. Stay away!

I received a Saturn S series PCM from Flagship One that was the wrong part number and not compatible with my 1996 Saturn SL2. I was immediately issued a prepaid return label and received a full refund from Flagship One. I then found a PCM on EBay from Flagship One which had matching part numbers on the OEM sticker to my original and purchased it. These older Saturn S-Series PCMs can not simply be programmed to the Vin# of the car. It must have matching part numbers on the OEM barcode sticker.

I have a delayed order H******* and called more than 7 times with their customer service attendances and nobody wanted to transfer me with my account manager or one of the staff members to review this delay. ONLY LAYS IS WHAT I GET FROM THIS COMPANY FLAGSHIP ONE.
VERY DISSAPOINTED AND DESPERATED. I HAVE CONCLUDE THAT FLAGS SHIP ONE DOES NOT CARE THEIR CUSTOMERS. THIS IS NOT THE FIS TIME I HAVE EXPERIENCED A DELAY WITH THIS COMPANY. VERY FRUSTAED..

The customer reps on the website answer my question promptly and I am a very satisfied customer. I will order very soon. I've heard from a friend that his jeep wasn't working and it was the computer. He ordered it in fs1 and bam! Problem solved!

I have been in business for thirty years and have been working on cars for fifty years. This is by far the worst company i have EVER WORKED WITH. They take your money and if there is a problem the dont give a flying CRAP. They keep asking me to send the unit back before they will send a replacement even though is said bill me again to save time. Supposed to be an American company yet I have not talked to an American yet. DO NOT USE THIS FAKE COMPANY. ----------- TEN STARS

I order an ecm. 4 weeks later I call them looking for it. They say they working on it. So I need a car and side to trade my car in. Call the next day. They say they shipped it. I'm like I don't need it. And for an 07 impala. I told them it had an 06 engine.
They send the 07 witch totally different. Out 170 dollars. These people have know idea what they are doing. Don't waste your money.

Took a month to get ECU for Toyota Prius 2011. Came with 5 permanent codes. Sent it back. Took another month. Said it wouldn't have any codes. Clean plug and play ECU. Came with 4 permanent codes. Sent back for refund. They charged me $85 restocking fee. Junkyard ECU full of codes. They have no software to clean ECU's. Don't waste your time with FS1.

ML 550 from Canada, grest custimer service from reps (especially Shenna)
2 years of car issues solved with a plug n play, key on engine off for 2 minutes then fired up like it should. Very impressed, these guys know their stuff. Highly recommend over the rest. FS1 rocks!

Purchased an ECM in January, Received it February 2nd installed it and had missfire move to different cylinder, diagnosed and found ECM faulty, contacted flagship one for warranty and was told because I was not aware of a TSB for this concern and now ECM is damaged no warranty and no concern for my customer being without a vehicle for 6 weeks already. Customer service does not exist at this company. Both reps I spoke to were rude and basically told me it was not their fault and I would need to purchase a new one. What a waste of money. Do NOT buy from them
