I also went to AutoZone and the tested the battery alternator and starter, all passed

 

A quick test wouldn't show long term issues with the charging system. You need to monitor the voltage of the battery from starting the car and monitoring it while driving. You find that when the two icons light up the battery voltage has dropped. This usually happens once the engine compartment had been heated up for a while.

Good luck.

Have a good day.

 

All the signs that there is an issue with the charging system.

Have a good day.

 

Like what, because I had the battery, alternator and starter all tested and all passed. I looked up the speed sensor that is on the transmission and it seems like that might be giving those symptoms but I am not really sure.

 

I had the same exact issue. Swapped all the speed sensors. New battery. New ground wires. Nothing worked. Swapped the alternator with a new 130 amp one and poof all gone. Been 3 months now no issues. Even drove to AZ from NY. Test your alternator.

 

I had the battery the starter and the alternator all tested at AutoZone and they all passed. That is why I am confused

 

That's why I stated that a two-minute test will not always show an electrical issue. This is particularly true of the Murano's.

I'll bet a hundred dollars that your alternator has an issue after running for some time, dropping the voltage output.

Have a good day.

 

I just took it for a ride. So before I started it, it read 12.1v I started it and it went to 14.1v. Has I am driving it dropped to 13.1v and then the lights came on and it was having a problem accelerate and it was jumping from 16.1v-17.1v

 

I am driving it dropped to 13.1v and then the lights came on and it was having a problem accelerate and it was jumping from 16.1v-17.1v

The charge warning lamp comes on when the alternator isn't charging the battery when commanded to do so or when it's overcharging. You seem to have the latter problem.

You need to fix whatever is going on with the charging system before addressing any DTCs you're finding when scanning the ECM/TCM because this electrical problem may be causing the DTCs.

 

Any suggestions?

 

What should I look out for

 

Could it be a faulty voltage regulator? If so then I would need a new alternator because it is built in correct?

 

That's correct. Such a common topic here.

 

Ok thank you, so stay away from aftermarket alternators correct?

 

so stay away from aftermarket alternators correct

YES!!!!!

 

Many people here will say oem only. I diy-ed a Bosch reman almost 3 years ago now in my 2nd gen and have been fine. Lots of stories here about failures though. Good luck finding an oem one. Lots of stories here about people going to Nissan and not able to get a Nissan alternator too. Look around and see what options you find. Let us know how you end up making out.
