I have a qx56 with 44k. On Saturday, I notice when I went to start it, it was a slow start. Didn't think anything else about it. Went to the store and when I went to start the truck it would not start. Battery was dead. Had my husband jump me which it took about 10 mins. to start. Went directly to test battery and was told that the battery was fine. Has anyone else experienced this problem? If so, have you found out what is wrong with truck?

Do you know how old is your battery? If you are on your original or if the battery is around 3 years old, it may be time to start looking for a new one. This vehicle uses a lot of juice so if you experience a slow crank and/or needing a jump start, the battery will most likely be the culprit.

yes check the battery first. the battery on the 2011+ qx is under powered for this car. it may last you 2 years at the most.

next check for DTCs at the obd port

worse case you may have a faulty IPDM but thats worse case.
