2014 Acura MDX: Sensitive Warning System

April 29, 2014

2014 Acura MDX

This will sound strange but I actually like when our L.A. freeways are only moving about 40 mph. They are usually moving much slower and as soon as they open up instant stupidity sets in. Every driver jumps to any lane that is moving fractionally faster. This is when accidents happen. And this is when I appreciate the Blind Spot Information system in our long-term 2014 Acura MDX.

I'm not a frequent lane jumper but I've driven my route home so many times that I know exactly which lane works best as I progress down the freeway. The BSI warning light in the MDX comes on every time a vehicle is detected in my blind spot and it stays on until they are clear. As soon as I apply the turn signal, even before I move an inch, the light blinks and the warning beep fires off.

At first I thought this system was too sensitive but then I realized it's really helpful. It's not always easy to see the action at the side of the MDX and you can be sure that whoever is hanging at your side is not paying attention to you. That's why 40 mph on an overcrowded L.A. freeway is good enough for me.

  • We'll get the standard "if your mirrors are adjusted properly you don't need this" responses but it is still handy and on multi-lane freeways you never know when the car to the other side of the lane you are aiming for won't notice you signaling and moving over

  • The woman who nearly hit me this morning could have used the beeping BSM instead of the 5 second blare of my horn. Also, the BSM only lights up when you turn on the signal or does it only provide an audible beep when the signal is activated. Most systems light the indicator whether the signal is on or not.

    The fact that you need to apply the turn signal makes it useless for the kind of drivers that need it most!

  • It's good to hear the BSI works efficiently. I wish they would add their "lanewatch", because in our Accord I really like it in traffic situations as well. It's cool to actually *see* the right-sided blind spot and anticipate the traffic situation. Sometimes I just leave it on because I feel like it :P It would have been interesting to hear about your experiences with LKAS and CMBS if you guys had an Advance to work with. Thanks for the blog!

    All that [non-permissible content removed] would drive me nuts. The beeping and booping and flashing lights. That's feel-good stuff...if you're not paying attention and looking around, that's not going to make up for it.

    All of the electronic aids can be disabled if you want to purposely never use them. I like having those aids, as even if you're paying attention it's still possible to miss something. And if an alarm from the BSI helps to prevent an accident, that's great.

    allthingshonda & banhugh: BSI just lights up when someone approaches your blind spot. Most times you don't even notice it. But if you use your turn signal, or if you don't use the turn signal but start turning into a lane anyway, the BSI will flash and beep. And, fordson, it's not 'feel-good stuff.' It's useful for the exact reasons Donna stated: the thoughtless and inattentive morons who like to fly past people. It came in handy on my first test drive when I was on an unfamiliar road. It gave me a split-second faster heads up than I would have realized on my own ... and sometimes that's the difference between avoiding an accident.
