It is warranty, so no cost if you can get the dealer to agree that it is the steering box.
“If you can get the dealer” is the issue
Just curious the cost of someone didn’t want to jump through 1,000,000 hoops with the dealers who say practically everything is normal and always discount forums as nothing but misinformation
Update: I got a quote of $695 for the new box plus an extra $75 until they get your old one back for a core exchange. That’s parts only.
