battery died replaced it worked great for a few days so tried another one then it died again. looks like it might not be charging. soon as i put the new battery in the second time the check engine light came on the abs and others cant remember all the lights. anyone ever have this problem. the rx only has 86k miles

 

Might be the alternator. Have the electric system tested to be sure.

 

The Check Engine Light (CEL) indication is those three lights appearing. Do you have a voltmeter?

 

i dont have one but yes them three lights come on
