In the cold NE weather my seat warmer takes at least 6 minutes in the low setting until I can start feeling it. After that it does its job nicely but I wonder if it takes that long on other MDXs. In the high position it may take a minute or so less but then it gets to hot.
In my wife's RX even in the lowest settings the warmth is almost instant.

I think mine is the same but hard to say since its garaged most of the time over night. My 2009 TL was the same way but one thing I noticed is that on the high setting after some time has passed, it somewhat cycles off and then back on again.

Lalin your experience on Acura vs Lexus seat heaters are exactly the same as mine. Both my old RL ( sold) and the MDX (current) seat heaters take sometime to warm up. My SC430 seat heaters warm up really fast compared to the Acura heaters. Nothing wrong with your heaters. That is just the way it is unfortunately.

Try using the high setting first and once it warms up, switch over to low.

It is a bummer that it takes that long. The point of the seat heaters is that you don't have to wait until the HVAC system warms up. In Acuras they don't act that way.
