Mishimoto Radiator

So, it's been over a month since Mishimoto has had their test vehicle and I've been dealing with their customer service.
Any resolution?
How is the test vehicle going?
I've been working with their customer service and they want their defective product back to study. I agreed but only if they give me a refund. They seemed to be complying. They sent me the prepaid shipping label to send back the defective rad., and are pretending to be working on the credit (don't know of any company that takes 4 weeks to process a credit). I still haven't gotten a credit.
They alluded to "possible chassis flex" as the problem, and according to Steve at Mishimoto they now have a test vehicle (had for weeks now) and we haven't heard anything. I'm guessing this isn't the case or we would have heard.
Not getting an update is telling, at least for me.
Now the question is, will they come through with their promise? Will they credit me the purchase price under the stipulation that I return the defective unit? Stay tuned, I'll let you all know where this goes, and don't hold your breath.
Oh, and here is the pulled radiator, first pic is next to the Griffin, the second is where the leak is, in the exact same place as the first (Mishimoto) one I replaced the Mishimoto "lifetime (which was 2 weeks)" warranty.
Any resolution?

Brian,
Sorry the refund process has been taking so long, I too don't know what's holding up the process. I'm going to try to reach out to 4-Wheel-Parts myself today and work with Justin to get this resolved, there's no reason this process should take this long. You will get your refund.
As per what I talked to you about on the phone, we initially thought that chassis flex may have been an issue but that was a working theory and we still aren't ruling anything out. The test vehicles that we had in were personal vehicles and have since been returned to their owners, after the engineer took any necessary measurements and 3D-scans. Unfortunately, these fixes take a lot of time and data; two vehicles for a few days is just not enough to begin making design changes. This is why we requested you send in your failed radiator, as we have with others. We would much rather take a lot of time and provide a new design that actually fixes the issues than make assumptions based on limited data that only serve to band-aid the issue. As soon as we have a definitive way forward I will post here with an update. I have also passed on the clearance issue that you mentioned to the lead engineer on the project to investigate further.
I apologize again for the frustration this has caused you and I will be doing everything in my power to get this issue resolved,
-Steve

Big thanks to Steve for taking care of me. I was able to get a full refund (radiator only, not time/coolant/and misc. hardware) for my faulty radiator(s). I have sent back my last failed unit for them to evaluate.
On another note, the Griffin fit, looks, and works great.

Haha, unfortunately we don't quite have the budget to buy a JK. However, if you want to take a road trip to Delaware and let us borrow it, I won't say no 
To reiterate, we do not know for sure if chassis flex is causing the issue or not, that is just a possibility to check once we do get a test vehicle in. Not all of the JK radiators we've sold have had this issue. In fact, only a small percentage have filed warranty claims; however, that small percentage is more than we'd like to see.
The factory mounting system does incorporate rubber upper and lower mounting bushings that seem to isolate the factory radiator enough and did not cause an issue during our testing. However, we may need to reevaluate the effectiveness of those mounts once we have a vehicle to test on. But again, all of this is theory until we can test on a vehicle
Feel free to let me know if you have any more questions,
Thanks!

instead of blaming body flex at ANY POINT do you ever think that MAYBE your quality control is shit? stop blaming the chassis, it sounds ridiculous. i dont understand why Mishimoto doesnt believe that failures can be related to the manufacturing and NOT the vehicle its going in. you do realize that bad welds will eventually lose integrity with enough heat cycles right? doesnt matter how sturdy the front end is. maybe you should take one of your radiators and heat cycle it with pressure in a lab, the exact same way it operates in a vehicle and eliminate the "body flex" and environmental influences. hopefully you will notice that shitty welds dont hold up, and vibrations from the road and engine do not help.
by the way, i've only put maybe 2K miles on the radiator even though it was installed at the end of 2015.
im heavily leaning towards going back to OEM since there was actually nothing wrong with my original.
this is on a 2010 wrangler.
here is my case number if you're curious; #ODV-207-25558

Landoawd,
Thanks for the feedback! We do like to adopt a spirit of continual improvement at Mishimoto. This is, of course, only possible through feedback from our customers on how we can improve.
Could you point me to exactly which products you're referring to and the experiences you've had with them? There are a lot of factors that go into efficiency and, as you said, all manufacturing processes will have errors; but that's why we offer our lifetime warranty, to try and minimize the impact any manufacturing errors may have on our customers. That's also why we respond to threads like these, in order to identify recurring issues and to bring the highest possible value to our customers. Test conditions seldom cover the entire scope of real world use for any product, but we really are constantly looking for ways to improve our products. That improvement often takes time and the input of many customers and professionals.
We appreciate the discussion!
Thanks again,
-Steve

Hi Rednroll,
I completely understand your trepidation after reading the Amazon reviews for this radiator. What I can say, however, is that we have sold a pretty large number of these radiators and the majority of customers have not reported issues with them. Nevertheless, we're determined to come up with a solution for those who are having issues. As I said in my last post, we have a 2008 JK in right now to test on and hope to have a 2016 JK in within the next few weeks. We certainly aim to have a path forward on this issue before spring and I will keep this thread updated with developments.
As always, our warranty will ensure that, if you do have an issue with one of our products, you will receive the most up to date version as a replacement.
We always appreciate the feedback and I hope to bring you good news about this product in the near future.
Thanks!
-Steve

Steve, according to Phomma in your customer service, and I quote,
"Mishimoto is not having any issues with these radiators nor are we aware of any quality issues involving our radiators and the Jeep JK".
So, assuming that this is the stance of Mishimoto's customer service, can you tell us all how many "lifetime warranty" replacements Mishimoto has sent out for P/N - MMRAD-WRA-07 over the past 12 months.
I think your customers would be happy to know this figure. I know I have now had two warranty claims in 4 months, and from this thread there are probably at least a dozen more.
I'd be happy to send my radiator back, tell me where you'd like it sent and pay me $30 (warranty replacement shipping cost) and I'll send it as soon as I remove it.
I'm not looking to get into a whole debate whether or not Mishimoto is producing a quality product, the proof is in the pudding (2 radiator failures in a combined 6000 miles). My time and the reliability of my vehicle is far more important than the $390 price that this product is selling for. I do not and will not accept a replacement for a third time. At this point if Mishimoto wants to save face, they should offer a refund for the receipt (proof necessary) amount should your customers deem that necessary.
To have to call your customer service have a debate about "if there is an issue" is piss poor.

first one never even made it into my vehicle because the brackets were all jacked up. second one started leaking few days ago (2,000 miles later)
absolute junk. chassis flex my ****in ass.
i should start using that business idea, next time i wire up a house and it catches on fire i'll just blame the homes foundation.

Of course! I hope this radiator meets your expectations; feel free to let me know if you have any more issues. I've also sent you a PM about possibly using your vehicle for testing, but if anybody else would like to volunteer their JK for testing please PM me!
Thanks again,
-Steve

but considering this is one of the largest JK forums, i would have expected them to try to defend their product a little more.
or maybe they are just hoping the thread dies so no one would see it
