CX-7 Starting Issue

[Jim3hoyt]

Hi all. Looking for some help. My 2007 CX-7 (75k miles) recently would not start. I turn the key and the lights and dash work but the car won't even turn over at all. The next morning its starts fine. I bring it to the dealer and they replace the battery. Two days later it happens again. I bring it back to the dealer and they can't find anything wrong. It now starts fine. It doesn't seem to be a battery issue. I am waiting for this to happen again. Does anyone have any advice or similar issues? Thank you for the help!

Could be several things but, first I would check the grounds (battery to starter and to chassy). Could also be a starter solenoid or even the ignition switch. I assume that the shop that replaced the battery did check the charging voltage and found it to be~ 14 volts?

Also, check the battery terminals are clean and securely in place. At one point I had a problem with starting the car on a new battery because one of the terminal clamps kept coming off.
