 My 2012 Toyota Corolla S lost sound three weeks ago and suddenly. Noting works - radio, CD, or connecting Iphone to the system. The center console is working fine - I can navigate, change FM channels, insert disc - but there is no sound. Took it to the Toyota dealer in Boston (car is being driven in Boston since last November). I was told that that radio has to be replaced at materiel + labor cost of $700. I did ask how can it happen - answer was that it may be due to the heat. Boston has been facing temperature of 92F for the last couple of weeks. I did point out that my other cars in Atlanta - Honda Pilot and VW CC Executive have not faced the same problem though the Atlanta temperature has been 98F and above for the last months. The gentleman did not have any answer. I just walked out without committing to the repair. If that is true, then I will really urge consumers to rethink about buying Toyota Corolla. This problem is widely reported on the internet. One pays lower price compared to the Honda cars with similar engine. But, if the repair cost is going to be like this for Toyota as opposed to Honda, then it is better one buys Honda car. At least it gives you a peace of mind. One does not have to deal with this kind of repair, leave your work and take care of it
