FWIW I have been deeply discharging and then fully charging my LEAFs and have had good battery life (considering my hot desert climate). You can see the results of my quarterly full discharge tests on my 2019 SL Plus in the 62 kWh battery thread. I try to have the battery between 40% and 70%...

DTC's would be helpful for offering insight. A high-voltage system ground fault could be the cause--if so, the ground fault could be in any of the high-voltage systems and wiring so the problem on the previous LEAF that the shop worked on could have been a fault in the A/C compressor wiring...

I had to use DCQC frequently when capacities of the smaller batteries in my 2011 (same as 2012) and 2015 dropped below my daily driving needs. As long as battery temperatures don't get excessively high (say 8 temperature bars or above), I would not worry about frequent DCQC. Cost may be high...

The compressor that is included with the Nissan flat repair kit is a good compressor that works well without using the bottle of sealant. I never use the sealant because it would make a mess of the tire and probably damage the TPMS sensor. It would also make a mess and require cleaning or...

I looked at the photo--the compressor failed and the debris from the compressor has probably migrated throughout the refrigerant system. The proper repair would be to replace everything that contains (or should contain) refrigerant since any debris left in reused parts would cause premature...

The heat pump system has a hermetically sealed compressor much like a home heat pump so it should not leak refrigerant unless some seal, hose, or other component fails. I have had zero A/C or heat pump problems and have been driving LEAF's since 2011. I presently have over 75,000 miles on my...

The 12V battery is being charged when the traction battery is actually charging or when driving the car. You should unplug the charger after the car is fully charged because there is higher residual current draw from the 12V battery when the car is plugged in but not charging than when it is...

The LEAF will only charge the 12V battery when in READY mode or when traction battery is actually being charged. Therefore, you need to plug the car in to charge or drive it for it to actively charge the 12V battery. It will not charge the 12V battery when parked and OFF. That is probably why...

I don't know what warranty coverage you have there, but the Nissan factory warranty in the USA covers the entire EV system for 5 years or 60,000 miles so you may want to check to see if you have warranty coverage before going further. Failing or failed 12V battery can cause many CAN Bus...

I saw that type of activity with my 2015 toward the end (battery was at 8 capacity bars when traded for 2019). The cells were fairly well balanced, but internal resistance was increasing. The increased internal resistance of the battery causes lower voltage at the motor terminals which causes...

Also, you may (most likely must) clear a bunch of diagnostic trouble codes (DTC's) associated with the brake controller and CAN Bus communication issues. This is discussed in other threads. You will need a suitable Bluetooth OBDII adapter and the LEAF Spy Pro application (either Android or...

This is a first post resurrecting my post from 2016. I can say for certain that there was absolutely nothing wrong with the 12V battery or system in my car at the time. The communication errors between the car and the DCQC unit were the sole cause of failure to charge on L2. Clearing the...

Accuracy is suspect when using dash displays to determine efficiency. A fair comparison would be to measure L2 charging energy from the wall after equal drives.

The article is a bit misleading. Since Tesla is a dominant manufacturer that does not go out of its way to supply replacement parts to independent shops, a lot of the excessive cost and long repair time is related to their monopoly. The Rivian repair cost was high due to being so new that...

You can download the owner manual (and many other publications) from the Nissan Publications web site: https://www.nissan-techinfo.com/Home.aspx I am not aware of anything with the car that will beep at a low volume and get louder. I suggest that you check throughout the car to make sure...
