Gear shift selector sticks in drive or reverse. A few years ago, the only symptom was clicking noise when lever was actuated, but now it does not return to a neutral position when you let go. Happens every time. Consequentially, unless you consciously return the lever to central position, pressing park does not take the car out of gear. If inattentive or a unfamiliar driver operates car, it will continue to move. I have been trying since November 2 to convince Toyota customer experience that this is something they should repair, is not a normal wear item, and began even before my vehicle was out of warranty. No luck. Dealer has offered a 15% discount from a $575 repair and has already charged me $45 to "diagnose".
