Gilly , sorry for the slow reply but I have been off line for awhile.
Dealer did find a code 065 & found an intermittent failure in the trans control unit signal to transmission. They had to order one , which took one day. Could not get it to work , order another. This unit worked . Performed B service , on rode test BAS light turned on. Found codes C1140 & C1504. They identified slight play in steering column causing steering angle sensor to loose memory. Replaced steering coloumn with steering angle sensor . Cleared all codes & roadtested. Found all functions OK.
Also replaced right front filler panel (plastic). All parts & labor at no charge. A loaner car was offered but not needed. Was satisfied with dealer.
