I have a voltage drop problem on my car. It is the ECO plus model. When the temperature (I am in Pennsylvania) got above 40-45 degrees the voltage on the electrical system has dropped to 12.6 to 12.8 volts. It is a very perplexing problem. Only when the temp is above 40-45 degrees does it do this. If the car is in park the voltage is normal about 14.2 to 14.3. As soon as I take it out of park the voltage starts to tick down. It takes about 1 minute or so till it bottoms out between 12.6 and 12.8. I have seen it get as low as 12.3 for a few seconds.
I have had it in for this problem twice. The first time the temperature was in the 30's and the problem did not present itself to the dealer. So they found nothing. Today it was about 50 and the problem was seen by them. They are now telling me that all Corolla's do this.
So I have a request from my fellow Corolla owners. Please check your Corolla's voltage after it is warmed up and in forward, reverse or neutral and reply to the thread with the results. I am very hesitant to use the car much because I am not sure if I am going to get stuck.
This is my third Corolla in a row. 2002, 2007 (still have this one) and now 2014. I really like the car but I am worried about this problem.
Any help would be greatly appreciated.
