Open the full vehicle complaint log (all categories)The Rear Cross Traffic Warning signal is installed behind rear head rest, which muffles the alert sound to barely audible, even when setting is on high. Vanandergriff Toyota dealership in Arlington, Tx., verified this information to me after bringing my car in four times for service because I was not being warned of persons and vehicles passing behind me. I've called Toyota's home office and told nothing can be done, as it was installed this way, although I am still asking they remove muffling material or change location of warning equipment. It is very dangerous, as persons and cars are not always visible due to parking location or blind spots. This should be a recall item. All other warning signals on front of car work properly. I was told by company representative to just use drive-through parking! Consumer contacted Toyota customer service and the dealership in Arlington, Tx. where it was purchased. Consumer was told nothing can be done to fix the problem.
