Hey all, been a couple years since I’ve posted anything here. Anyway I have some weird stuff going on with my 2009 MDX with 226k miles. Recently finished putting in new tie rods, sway bar bushings and end links. Also did new ac condenser and radiator and bumper and headlights due to my son rear ending a jeep. In my inaugural test drives it will randomly just feel like the front wheels will stop turning for just half a second and then return to normal. No drove it all around the other day and it only did it once, but it’s unlike anything I’ve ever dealt with. It’s like one of the brakes suddenly engages for just half a second but then returns to normal.
To make it weirder, I put it up on jack stands today and ran it with the wheels off the ground. I first noticed the rear brakes must be grabbing a bit because both rear wheels squealed while the car idled in drive. But the issue that I really wasn’t expecting is that the front drivers wheel barely turned at idle while in drive and turned slower when given any throttle. Also, going back to my first problem, the front wheels would occasionally stop turning and the engine bog down for that half a second when I’d press the accelerator— it didn’t do it every time, but it did do several times. ANY ideas on these weird symptoms?
It may be completely unrelated but a couple of things: I haven’t aligned the car yet and now the VSA light comes on after s as bout 10 minutes of driving; I know the intake boot has a small crack; before all of these repairs the car would surge and then almost die when really warmed up and stopped at a light.
I’d be very grateful for any guidance on this. Thanks!

perhaps it's ABS related, was there damage to the ABS or wheel sensors at all?

 

Hmmm, it’s possible I damage the abs sensor while replacing the tie rods and end links. I’ll check that out. Still not sure why front left wheel is turning so much slower than the other 3.

 

You have SH-AWD and car is shifting power around and using VSA system as it thinks you are out of control!

 

Makes some sense, but what causes that and how do I fix it?

 

Check that all wheel speed sensors are working properly. Those are required for VSA, ABS and SH-AWD to function properly. From there you need to start seeing if the steering rack is binding or what is going on. My previous comment was with the car in the air all 4 wheels will not spin like a traditional AWD.

 

Ahhhhh. I will check that. Thanks!
