Undercover was installed by dealer. Rain collects on it and when I lift it up the water run down and into the bed of the truck. Has anyone else experienced this issue... any other solutions? Thanks.
I had the same rain problem on my new truck/new cover, which was dealer installed. My truck is not a Tacoma (boo hiss), and I know I'm not supposed to be here, but I may have an answer for you. I drive a new F150 and my new Undercover did exactly the same thing. Problem is Undercover has redesigned the hinges to supposedly prevent the front rubber gasket from rolling under itself at the bulkhead. My new cover shipped with the wrong (older) hinges. Not sure why, because I bought my 2009 in May so unless I'm the first 2009 F150 buyer who ever installed an Undercover....
Anyway, it took a lot of calls to the dealer (turned out to be useless once they had my money) and Undercover before I finally got my free correct hinges. Had to drill off the old ones and rivet on the new ones myself (hence the useless dealer comment above). But since it took so long to get to this point, now the rubber is formed poorly and still rolls under the cover. So now Undercover has sent me free replacement rubber and glue, so when it warms up here in Canada again I'll scrape off the old rubber and put on this new stuff. It's too cold to do that now, the rubber may not form correctly again, and it only leaks a little when I lift the hood wet, so it's not a huge deal for the winter anyway.
So, sorry for intruding on your Toyota forum, but maybe this is a cross-platform problem you have. You can always call Undercover toll free at 866-900-8800 and see what they say. They're pretty helpful, although they don't always follow through on what they say they're going to do unless you remind them a few times. But they're pretty accessible. I've spoken to their customer service people, CS Manager, their engineer, and their president, and they all seem to want to help.
Good luck with this.
