I bought my 2007 LS in feburary and for the last month, four of the buttons on the radio stop working. It is always the same two station preset buttons and the two seek buttons. It is starting to happen daily now where they stop working for 30 min or more. Anyone else having this problem?

 

Does it throw up the "ERR" and "LOCK" messages on the display?

 

No, everything else works like is suppose to, you dont even know the buttons stopped working untill you try to press them and nothing happens!!

 

Sounds like something covered by your warranty. You should go to the dealer.
