I searched several old threads and found many had similiar issues with their 07 and 08 models and a few who had problems with their 09 models as well. My factory JBL system (with that horrible ugly sub box) is giving me fits. I have noticed the panel lights shut off at random, volume controls are sketchy, and the FM reception is horrible most of the time.
The ugly sub box can be turned on and off with a little switch on the box and when it is off it sounds a little better however still is not very good. When the sub is powered on I have to back the bass controls way down to avoid horrible distortion and can not find a sweet spot on the settings to actually enjoy listening to any station.
From what I read in old threads Toyota is well aware of issues and I found many members had to wait months for a replacement due to back orders. I have not seen any recent threads on this and wonder if anyone can tell me the status on repairs currently or maybe even if the actual source of the problem has been found.
I know nothing of stereo components nor how it all works however I do know that for a 28k vehicle the stereo system is simply crap. I am visiting the dealer this week and hope they may be able to resolve this for me.
My question is will simply replacing the stereo solve the issues or is the problem somewhere in the sub or factory amp? I read old threads where some had better results by simply swapping out with a second factory unit however for some this did not help. Others got better results by changing the amp so I am a little confused. I would hate to wait months for a replacement head unit only to find they replaced a defective unit with the same defective unit.
So has anyone here actually resolved the problem on a 2009 model while using factory parts and if so what did they actually replace? Did the dealer give you a hard time or was it a simple process involving a known defect?
