Cable Internet Issues -- bad cable modem?

I've been having a lot of problems with my Comcast cable internet (both performance, and with their service, but this question focuses on performance) over the past few weeks. Is this really caused by a bad cable modem? Many details inside.

Downloads are bouncing between very slow (~1.5Mbps per comcast's speedtest site) and very very slow (small bits of text will load on pages, and that's it). Interestingly, upload speed on their test site was ~5Mbps. Following 7 support calls, 1 chat, 1 hangup on me by management, 0 responses on twitter (other than from AT&T) and 2 no-shows by comcast for scheduled tech appointments, someone finally showed up. He looked at the modem, listened to me explain the problem, and immediately said that the modem is bad.
I currently have a Motorola SB6141; I purchased it March 31, 2013. My question is: before I go out and buy a new modem, is this logical? Does it make sense that a bad modem will cause bad download speeds, but not upload? Do these things really die within 14 months? Wouldn't it show up as bad in their diagnostic tests (that all show the modem as working perfectly, according to multiple support people)? Any other suggestions for me to try, before replacing this stupid thing?
They refused to plug in a test modem to see if that would get different results, unless I agreed to rent one from them.
Thanks for your help.
