What codes are you getting? Please post the actual code numbers.
Are you past your 5/50000 warranty?
Did you replace any tires recently??
If so and this started afterwards then go back and replace the rest so all 4 match…
If not then check the tread depth to make sure all 4 tires are close in tread depth, if you installed them many miles ago and never rotated them, then that could be throwing the AWD off as the fronts are now worn out and the rears are still good…
Of course you could have many other possibility’s…
