FRONT mechanical LSDs are pretty rare except for really serious off-road vehicles such as the Hummer. "Virtual" rear LSDs using the brakes individually, a form of TC, have become fairly common. So you may find vehicles with "virtual" front LSDs but even those are unlikely to provide a seriously limited locking level due to the feedback to the steering wheel.
With a "base" FWD such as the MDX the most likely reaction to even the slightest level of front wheelslip/spin would be INSTANT engine dethrottling accompanied by moderate braking of BOTH front wheels.
Unless it has a TC disable PB as do most F/awd vehicles.
Just so you know...
'10 & '11 Toyota RAV4 FWD is equipped with an LSD. Acura TL Type S Sedan -'07 & '08 - yep... LSD. There are more, but you get the point.
Couple of rare cars there alright.
Front Mechanical LSDs are far too dangerous to thumbs and fingers to put in the hands of the general automotive buying public, UNWARY public. "Virtual" LSDs, maybe, but their "firmness" can be firmware limited.
TC, obviously, could be referred to as a form of LSD.
My guess is that someone in marketing is being a bit too liberal with terms. I'd bet that what these cars really have, as do most FWD vehicles, is a hyperactive TC system. Instant engine dethrottling along with moderate (ABS "rate") braking of BOTH front wheels when even the slightest level of wheelspin/slip is detected.
I'll put money on that if you wish.
"Virtual" LSD as a "Subset" of TC.

Anyone have any info on the FWD diff type?
Toyota RAV4 FWD has an LSD, want to know if a RDX FWD does as well.
Thanks
Loss of traction on the driven wheels, or wheel, of a FWD vehicle is considered a VERY serious matter.
I suspect you will find the RDX, or any modern day FWD or F/awd vehicle, has the very same "LSD" implementation.
I found the part #'s for both...

Fully open diff.
No lsd for you.
No MECHANICAL lsd, but a "virtual" one.
