Had the PDM blow in a freak incident at a charging station about two weeks ago: parts of the QC?! circuit was burnt out, and the car had a permanent "EVSE plugged" status which basically disabled the car. It happened when we attempted to plug in to start the charge at public L2 charging station (weird how it affected the QC part....). Eventually had to be towed to the dealer, and got a new PDM replaced under warranty (whew). The replacement part was 292C0 3NF7D. While waiting for the tow I also noticed that the 12V was sitting low at 11.6 when the car was on, and since the battery was the original and *could* be on its last legs, I made a note to replace it ASAP.
It charged fine on the AV charger at Nissan, but during the very next L2 charge at a public station it ended abruptly at around 70% or so. After that, the car disabled itself when we attempted to leave (as we were pulling out of the parking spot, the EVSE plug status suddenly came on and car was suddenly disabled again). This time, re-connecting the 12V eventually cleared the status. I decided to replace the battery just in case. Since then we were able to drive normally, but charges at various stations would suddenly stop, and then for a while we wouldn't be able to charge. Did a close to full charge (97) on the AV charger at Nissan over the Christmas break and left it there.
On the 26 of December we took the car home from the dealer, and we did some short charges over the next few days on public stations (30 minutes each time), as well as a 30 minute quick charge without problem (other than being -25 and charge rates were super slow). We finally got our JuiceBox installed, and was able to do longer charges at home. This afternoon, we did another charge from 20% to about 80, and the charge again stopped abruptly. Trying to pull the car out of our driveway it suddenly disabled again with the EVSE plug light. This time since we were in our back yard, we had time to dig a bit further: the 12V battery was again sitting low at 11.6V according to LeafSpy, signalling that the 14V->13V startup routine didn't run. After we disconnected and reconnected the 12V, the voltage on the 12V went back to normal (starts off at 14.4, then goes down to 13V after a bit), and, as expected, the EVSE plugged status disappeared and the car was drivable again.
Anyone else seen anything like this before? Initially when considering the AV EVSE vs public chargers we thought it may have been the diode issue, but now it looks like something else completely since charging generally starts off fine on other chargers. Our current guestimate is that somehow the charger can randomly malfunction during a charge, and if it does, seem to crash the system in such a way that the 12V program gets messed up, and certain critical features in the car rely on the 12V having enough power (such as clearing/checking for the EVSE plug status). This is pure conjecture of course... also the 12V battery may be a complete red herring as we've left the old battery disconnected for quite a few days out in the cold and it's still reading 12.6V. Haven't load tested it yet, but it's *probably* still OK based on what we're seeing above with the new battery.
Will be bring it back to the dealer when they're open next on the 2nd of January, but at this point they're not really sure whats going on so any external points of reference could be helpful.
Thanks in advance!
