It's nothing the mechanic did. Same thing happened when I had the car towed on a flat bed. The wheels we're ratcheted down and pulled out of alignment enough for the car's stability control to go in limp mode. The steering wheel was at the 11 o'clock position.
Alignment made everything go away.
Old thread, had to ask about the LR4 having all the faults mentioned after being towed, rather rachet strap tied down.
Rachet strapped down on a full off the road tow this placing the suspension out of the sensor's normal operating range causing alignment issue warnings to appear?
Does rachet strapping down a LR4 end up bending up the suspension linkage now all out of alignment after released from the rachet straps causing the issue?
Reason asking a block away neighbor last weekend with a LR4 returned home from the snow packed mountains and went through several deep snow drifts and now has suspension fault warning issues. I asked "did you hit anything?" No just driving in snow their reply.
They drove it home slowly without issues. What ya gonna do 10:30 PM on a sunday night in stormy weather anyway?
It's not a daily driver vehicle. I told him to park it and find more about these issues before spending money wildly at alignment or dealership shops.
