Hello,
I want to share my experience for folks here who may be having similar issue for better troubleshooting.
Started with slow cranking when you press engine start button it cranks 2 or 3 times and stops press button again all lights dim like as if battery is dying and cranks slow slow and then starts maybe have to try third time as well.
I checked online and most of people mentioned same problem in different vehicles being starter going out.
I checked battery with multimeter, after about 4 to 5 hours of turning off engine it was showing around 12.4 volts. I cranked motor and the voltage reading was 13.5v while engine running.
other signs i experienced was that the courtesy and interior lights turn off and i had to manually put them back on auto every time. Another related issue was that the navigation was taking some time to boot and show progress bar with text saying system booting which never happened before and take 10 to 15 seconds everytime i start. One more issue was that as soon as vehicle turns on the lexus link calls itself and had to turn off.
So i took it to autozone and had them load test battery which revealed that battery apparently has a bad cell so its not a starter.
Next thing i called lexus since it has lexus battery, they told me that warranty works like this: first 2 years free replacement, year 3 and 4 50% proration and year 5 6 and 7 25% proration. My battery is 3 years and 2 months old so they will charge me $104.65 to replace battery which i believe better than buying $100 walmart battery.
