Mishimoto Radiator
For those of you considering getting a full aluminum radiator once your OEM fails, I would highly recommend you consider another option. Although Mishimoto customer support has been adequate, I have found the quality control of these radiators to be less than satisfactory. I am now on my second lifetime warranty claim, and I salute them for honoring these claims. However, the fact that I have had two cores fail in under a year is disappointing to say the least. Additionally, the shipping cost of the replacements, and the MOPAR HOAT costs as well, has made this a pricey enterprise. Not to mention the time spent communicating with customer support and the time necessary for installation. If it fails again, I'm just going to have to eat the price of the radiator and likely just get a replacement OEM. Just a heads up for those considering this attractive yet disappointing product. Of course, I cannot speak for other owners and maybe my experience is an anomaly.

I just put a Mishimoto Radiator in my JK in July and it has been leaking from the core as well. After reading multiple complaints about the same thing, just going to straight to OEM to replace it. So frustrating

As someone who's seen Mishi products in a number of circles, this is unsurprising. Their core quality has always been subpar, and my suspicion is that they bulk buy from overseas, weld on tanks (they're horrible welders), and pass their rads and intercoolers off as "performance".

Just an update on it, I'm certainly ignorant when it comes to evaluating the quality of their product and what aluminum can tolerate. However, I have had excellent communication with their customer support, who continues to impress despite my frustrations.
They requested a survey about my vehicle that they are requesting from the Jeep JK customers who have filed for a warranty replacement. I inquired why, and this was the response:
"We have noticed that there is an issue with the construction of the Jeeps more-so than there is with the radiator. The front end of these jeeps do have quite a bit of chassis flex that is causing premature failure of solid aluminum radiators, and we are in the middle of working on a solution for this at the current time; unfortunately we do not have an anticipated completion time-frame for this though. This is why we had sent over that brief survey to gather more information for the vehicle. To help keep this from happening again, our production team has recommended going over the front end of the jeep and updating any worn out bushings or loose components with upgraded bushings if possible to help stiffen the front end of the vehicle."
I would need input from other members to confirm if some of this is true. But regardless, I appreciate the customer service response.

At 185,000 miles I replaced my perfectly good original radiator with another OEM radiator because I had a trip above the Arctic Circle. I ended up with an OEM radiator, after researching aftermarket offerings and hearing many similar complaints to what I'm reading here. And, that is what the mechanic doing the work, a personal friend and highly experienced, recommended. I'm now over 200K miles and will be delighted if I can get 400K miles out of the Jeep. I honestly see no reason to opt for one of the aftermarket ones until such time one can be assured that what they install will work.
