Radio/tape Cd Player problems of the 2000 Dodge Grand Caravan

My infinity radio system started losing its time and when I shut the car off it shut the radio and the next thing I knew the radio/cd/cassette player was dead with a cd still in it. I brought it to my mechanic who said with this make/model and year van this was very common for the radio to die. He said they had numorous people complain and have to buy new radios. This is a 3 yr old van I should not have to be replacing the radio in it. Of course I cannot even get a comparable system without spending at least $350. 00 I think if this is happening to Dodge Grand Caravans a lot then there should be a recall and the manufacturer should replace the system.
