Can a passenger's weight damage seat heaters?

The max interior load for your car is 850 LBS.. and yes I would say very heavy passengers will damage the heating coils or elements in seats, it just makes sense, wouldn't you say ?

Thank you for your quick response! Yes, I thought so. At what point should I limit a passengers' weight on one seat? (I have a couple of fairly large family members.)

I would say no more then 275 lbs, not its not safe as well...

"No more than 275 pounds"? No disrespect, but I disagree. I have owned many, many cars in the past that have had seat heaters in them and have never had an issue. In fact, I currently have a 2014 Tundra and a 2014 Camry XLE with seat heaters. Both cars have over 50k on them and I use those seats almost every single day due to back pain. I'm a NFL-lineman sized man, 6'7" 350, and I have NEVER had a single problem out of any of my cars. Unless 2009 Accord seats are weaker than 2007 Corvette seats (which I doubt), you should not have a problem. Of course, if they are plopping down into the seats instead of seating themselves in a normal manner, I could see that being an issue.

Seats wear out like everything else. The more weight, the faster the wearing out.

So who do want to tell they are too fat? The mother in law? ;)
