"06 MDX with 69K miles. Lately going from stop to accelerate either right or left turn the VSA light momentarily flashes and car nearly stalls. Otherwise drives well.

 

VSA flashing means that the car is momentarily losing traction.
which corroborates with what you've stated; "upon acceleration"

might want to rotate tires, or get new tires all together. as tires will play apart in traction, as an old bald tire will lose traction. no grip.

 

Tires are good. No loss of traction when this occurs. It is not everytime I turn. Yesterday drove to end of street, stopped, turned right and the VSA flashed for 5 seconds. Then no problems until later in day. Same thing except after a stop turned left and got that 5 second VSA flash. So it was twice on that trip which included a fair number of stops and turns. I know I will need to get this looked at but was hoping to gain some understanding before mechanic plays trial and error with parts.

 

the flashing of VSA means loss of traction.

 

 

Also, if a mechanic is playing trial and error with parts...that is not a very good mechanic.

 

Just backing up previous replies. Not all tires screech/squeal when losing traction so maybe you don't hear it but if the light is momentarily flashing upon acceleration from a stop it is in fact losing traction, then the VSA modulator sends a command to the PCM to momentarily reduce engine output until traction is regained.

Sounds like you drive like I do lol. If it's an ongoing annoyance you can make habit of turning the VSA off or if you're good with electrical and really ambitious you can permanently disable it without throwing codes or a malfunction light by depinning a couple of things. Something I've done on my old MDX.
