Why do my battery keep draining.....even after I put
in a new battery and starter and alternator.....
Check what accessories are plugged in while parked. Some will drain the battery to such an extent it won't start.
I am having the same problem with my 2010 Buick LaCrosse CXS 44,000 miles. I had this problem 4 years ago and they replaced the battery that was still under warrranty. Now I'm having a problem again and nothing is under warranty I just recently bought it another battery and I can tell that it is weakening with every start. don't know what to do.
I have replaced the battery 3 times in my 2014 Lacrosse. Please tell me why. The last one only lasted 13 months. The phone notice comes up saying that it is on and I have disconnected it on the steering wheel. I believe this is a defect in the system. Please help. Janet
