Two problems related to radiator have been reported for the 2015 Dodge Challenger. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2015 Dodge Challenger based on all problems reported for the 2015 Challenger.
I purchased a used 2015 Dodge Challenger scat pack with 6800 miles. The radiator started leaking at 7100 miles. I found the leak after highway driving. A puddle formed under the passenger front corner of the car. The dealer will not replace it since the oem warranty is expired. There are quite a few other owners with the same issue. I believe a recall is necessary and a possible revamping of the radiator so this does not happen to future owners.
My 2015 Dodge Challenger scat pack has developed a radiator leak that seems to lose coolant when driving. I had first noticed the coolant level dropping back in December, 2017 while my car was in storage. It was brought into fields Dodge who diagnosed the leak but could not tell me where exactly the leak was coming from. I called Dodge customer service and they refused to offer anything on resolving this issue even though my warranty expired 3 days ago on March 12th, 2018. They do have a technical service bulletin regarding radiator leak problems but they are not doing anything about it, even for customers who have low mileage but expired warranty. The dealership service manager mentioned the leak may be coming from a seam between the plastic and aluminum. The radiator is of inferior quality and there are numerous others on Challenger forums who have mentioned radiator problems on their Challengers.
