Have a used 2010 S I purchased in January. Car now has 56,000 miles. US model. I think it has every option minus stripes and satellite radio. It does have the navigation system.
Starting to have a electrical issue. I thought I would check here before proceeding. I suspect I have a battery that is on its last legs..
Car starts no problem. No hint of a failing battery.
Car does have the original battery. It does have a dark eye.
Car does have the IBS ground cable sensor.
So...here is what the car is doing...
Have gotten the 'increased battery discharge' message a couple of times.
Navigation system seems to be slow to boot up.
HVAC system will often go thru a door cycle at start up.
A couple of times the max speed HVAC blower reduces one speed down.
The navigation unit will shut down about 2 minutes after engine shut down. Used to be 7-8 minutes after shut down.
As mentioned..I suspect the original battery is showing it's age. That said...I thought I would check here in case there is a body ground or maybe the IBS is going bad before replacing the battery.
Anybody seen this? I would hate to buy a $150 battery and find out there is a common engine ground kind of issue..
