I purchased the ProForm treadmill 2 years ago and also purchased the extended warranty for 4 years. Almost 6 months ago the treadmill started to make loud noises when I went 3.0 mph or faster. I immediately contacted ProForm/iFit to use implement my warranty and have them send a technician to fix the problem. For the past 5 months we have traded emails that keep asking me for the same information. I have even sent a video with the noise clearly apparent. Their latest email now has asked me to dismantle the treadmill tighten all of the bolts, take the motor cover off, etc. Isn't that what the technician should be doing because it is under warranty? If I can't get this issue resolved in the next month, I will request a full refund of my warranty. This is ridiculous!
