That can't be true. I'm sure at least one unit of every safety related part of every vehicle ever made in volume has failed yet no recall was ever issued.No threshold for the issues related to the areas mentioned below:

Of course but that type of wording may give them some legal wiggle room.
@JRP3 Tesla has to report every possible safety issue they investigate to the NHTSA. They released a press statement discussing their investigation, and they took action. But still haven't reported. Not reporting is a crime, fines will have to happen. No possible other outcome.

Tesla wants us all to forget what they promised back then!
51kw from 25% battery up to 55%...was not too cold, 4deg C
That battery was cold. Pack needs to be well into the high 25C to charge at peak rates.
Our 2013 charges at 40kW when cold and 90kW when the pack is warmed up. Driving on the street or highway is nowhere near sufficient to warm a battery. You need to hammer it as Bjørn Nyland says. Many full accelerations for 5 seconds and regen and repeat. Try it and you’ll see much better charge rates.
I see this too! my MX75D, after driving for 75 minutes on the freeway, pack was warmed to about 100*F, plugged in, ramped up to 85kW-ish, after a minute down to 60, and stayed there. Arrived with 1 mile remaining range due to the massive snow storm.I had the exact same rates of charging and I followed Bjorn's rules and was driving for 45mins. 33-75% took 50mins rates. Max 57kw for short time down to 36kw.

You should tell the navigation to navigate to the SuC. Then the car will automatic pre-heat the batteri before you arrive. The icon will also be visible in the App.Just curious about optimal battery charging for my Model S P100D...if I'm headed to a supercharger to plug in and it's cold outside, should I flip the car into "Ludicrous Plus" mode to warm the battery before arrival?
if your battery cooking system wasn’t blowing warm air out of the front of your Model S, then no the battery wasn’t up to temperature.
Our old Model S charges at max rates when I drive. And when supercharging the battery cooling system runs very hard vibrating the car from the fans and compressor motors running.
When my wife drives , she usually sees 40 kW rates when supercharging, no fans running. She doesn’t drive the car hard enough to warm the battery.
This is the same behaviour for the past 4 years. No charge in behaviour over 100000 km, hundreds of supercharges. I have a OBDII device that has recorded every supercharge and trip for that period and posted details upthread a few months ago.
Supercharging speed is almost perfectly correlated with the way the car is driven. Hard diving results in fastest charging.
That should be obvious - the NHTSA doesn't permit theft or warranty violations and discloses drastic modifications made before action is taken with federally mandated public disclosure. It's all part of their own legal requirements. And, of course, I read the documentation from the NHTSA demanding Tesla turn over that data to aid in their investigation into chargegate & batterygate, and I know for fact the NHTSA will never permit downgrades like Tesla has pulled. If they had been included, we would have received physical paper letters informing us of the actions taken on or cars. (informed consent is what they call it in my industry, and the NHTSA has similar requirements). It's a very big deal. Lack of informed consent will probably result in additional punitive actions against Tesla but that's a separate set of fines from the not reporting you had asked about.How do you know they haven't reported an in-process investigation to NHTSA? It isn't like NHTSA publishes every piece of communication they have with Tesla. (As can be seen from Tesla having reviewed many SUA incidents with NHTSA but that wasn't published on the NHTSA site.)
The fines stem from a year-long NHTSA investigation into every Mercedes recall between 2016 and 2018 after the agency, among several federal violations it identified, found the company late in mailing owner letters and omitting critical information in its filings. The automaker must pay $13 million up front, with another $7 million in hanging fines if NHTSA determines that Mercedes is delaying or failing to improve its recall processes. The company will be audited by NHTSA for the next two years.
By law, every automaker must submit quarterly reports to NHTSA that show the progress of ongoing recalls along with all known claims of property damage, death, injury, warranty claims, owner complaints, and internal studies for their past and present models.

When leaving (at the current temp) in the morning, my battery is approx 10C. When arriving at work the temp is approx 26C. The battery heater has not been on. So the warm comes from the drivetrain.
Another observation. When leaving in the morning nothing happens for the first 5-10min with the temp. (battery heater temp, and battery inlet temp.)- temp. is constant. Suddenly the inlet temp raises - my best guess is that heat from the drivetrin is used to heat the battery - a valve is opened.
When navigating to a SuC, I can see that the battery heater is turned on approx 10min before arrival, unless the battery is already warm.
PS temp has not been below 0C here this "winter"
Forgive me as I’m late to this party and haven’t been able to read through all of the posts.
I’ve always been concerned with battery degradation and even researched prior to purchase to try and mitigate this, from the start.
I don’t do much if any supercharging and I maintain the battery between 20-80%. It only became alarming during the summer (I believe) when my 80% charged was not cutting it and I had to bump my charge up to 90% as miles in tank suddenly dropped and my round trip commute was suddenly closing in on 20%. This change in my battery seemed very sudden and I chalked it up as the luck of the draw as I felt I had taken care of my battery.
From one of the posts I used the formula (avg consumption X projected range / % left in tank). I came up with 65,984.84.... on a Tesla S 75D. Mine was purchased in Dec 2017 (face lifted version). I tend to drive more aggressively then most Tesla’s. Not sure if my driving characteristics have created a condition X or Z, which Tesla identified and in turn capped. As I have Supercharged maybe 20 times in 2 years.
thanks for any input!
