Dealers will inspect and replace the front brake modulator valves, as necessary.  Some vehicles will have a software update which will alert driver when a replacement is required.  All repairs will be performed free of charge.  Owner notification letters were mailed beginning October 13, 2023.  Owners may contact DTNA customer service at 1\-800\-547\-0712.
