My experience:
New Gen 3 wall charger worked well for 7 weeks and then in mid September the blinking reds appeared after about 30 minutes of charging and charge rate dropped by 50% to 20 amps (have a 50 amp breaker). I started following this thread shortly thereafter and last week checked for my current firmware (0.8.58) and called Tesla (510) 249-2490 option 2. After a short wait the tech came on, asked for the last portion of my VIN as well as for the TPN and serial numbers for the wall charger. With those in hand he ran a test on the unit and concluded that the firmware update to 1.3.0 was in order and set up same with the request that I wait a couple of hours before using the unit. He also said that they would monitor the unit and let me know if I needed a replacement. No follow through on that point yet. After the two hours passed I turned off the breaker for a minute and then checked to see if the new firmware was in place. However, before I could do so I had to re-enter the original WPA2 (pin) number for the charger. Fortunately I still had the Quickstart Guide for the charger which shows the pin. The new firmware is in place and performance has improved but the issue is not resolved. My recent charging experience (4 sessions) results as before with the blinking reds after about 30 minutes. However the charge rate only drops by about 10% as it fluctuates between 34 and 37 amps vs 40 normally. The cable and plug are warm but not hot. So it seems that the firmware yields a better experience but that the hardware still harbors a defect. Interested to see if those of you with new WCs experience no blinking reds.
