Tesla has escalated my case to engineering after the service center was unable to account for my drastically reduced supercharging speeds. Below is the e-mail I sent to them and asked them to share with engineering. I also included pictures to prove the data I provided and for reference. Figured I would post this here in case anyone else can relate or has had similar issues. And please, spare me the basic braindead troubleshooting steps for supercharging. I've tried them all and it's insulting at this point. And obviously Tesla is finally taking this seriously as it has been escalated to engineering. "I am currently charging at the Centralia supercharger. I arrived at 2:34pm with 10% SoC, outside temperatures in the mid 80s, driving a car that was well warmed up (3.5 hour drive to the service center this morning, several short charging spurts at the service center, then 2.5 hour drive [heavy traffic on I-5] to the supercharger here in Centralia), and I picked a stall that wasn’t being shared with another Tesla (I plugged in at 1A – no Tesla on 1B). After allowing a few minutes for the charge to ramp up, my charge rate was only 50 kW at 13% SoC. At 20% SoC, I was charging at 52 kW. At 31% SoC, I was charging at 52 kW. These slow charge rates prompted me to move to stall 3A. There was no Tesla at 3B. My car suddenly jumped up to 84 kW at 33% SoC. At 41% SoC, I was charging at 86 kW. For reference, 87 kW is the fastest I have been able to supercharge since last summer. Last summer, shortly after taking delivery of the car, I was able to supercharge much faster than that. At 42% SoC, A model X entered and hooked up to stall 3B. From what I have read, the newly arriving Tesla’s charge rate should be throttled since I was here first. However, after the X hooked up, my charge rate plummeted to the 40 kW range. By 49% SoC, I was maxing out at 56 kW. By 59% SoC, My max rate was 49 kW. At 60% SoC, it was now 3:14pm. I started charging at 2:34pm. That means it took 40 minutes to get a 50% charge. Regardless of the throttling, I know that these speeds, even my max speed, is not normal. There must be some explanation as to why my charge speeds are so slow now. I have used many superchargers in 3 different states since last fall and, no matter the conditions, I cannot charge faster than 87 kW. Most of the time I am charging MUCH slower than that (as demonstrated by the case above). Here are the pictures for reference to corroborate the above:"
