NHTSA is considering a complaint by Tesla owners about a software update that led to the loss of battery capacity earlier this year.
They claim that this is a potential risk of fire.
Earlier this year, we reported several reports from Tesla owners that there were significant falls within a short time span of 12 to 30 miles.
Only Model S and Model X 85 kWh batteries, which were discontinued in 2016, seem to have affected this moment.
For most owners, the fall in the range occurred after the Tesla software update for 2019.16.1 and .2.
Tesla owner David Rasmussen got one of the harshest
At the time he told Electrek:
"My 2014 S 85 model got a nominal range of 247 miles through May 13. Now after the next update, it has continued to go down to 217 miles This is an 11% drop in 5 weeks. "
Rasmussen has been predicting degradation of his Model S's battery capacity over the last 100,000 miles or so, and the latest drop is quite obvious:
He went to its a local Tesla service center with a problem, and like most other owners who reported this problem, he was told that it was "normal degradation" of the battery.
Following our report, Tesla said that the purpose of the upgrade was to "protect the battery and improve battery life", and this resulted in a loss of range only for " a small percentage of owners. "
The automaker said it was working on a solution, but nothing changed in a few months, and Rasmussen
complained about both sustained loss of range and that Tesla didn't understand why they needed to" protect "battery.
He believes this happened because of a series of fires.
After filing a complaint, Tesla told us that they had started releasing software updates to help the loss of range, and stopped referring to the need to "protect" the package.
He now also lodged a complaint with the NHTSA Defective Investigation Directorate (ODI):
"On September 19, 2019, the Defective Investigation Office (ODI) received a defect request dated September 17, 2019 asking NHTSA to initiate a Tesla Model Defect Investigation and Model X Cars that received revised Tesla battery management software in one or more OTAs since May 2019. The applicant alleges that the software updates were in response to a potential defect that could result and not to fire in a battery-related accident and that Tesla should have informed the NHTSA of this potential defect and have a safety recall, and the complainant also alleges that this software update shortens the range of the affected vehicles. the petition will be added to the public file on this defect petition, and the ODI will evaluate the petitioner's claim to determine whether the petition should be filed or denied. "
NHTSA is investigating this question to see if there will be a defect
We have contacted Tesla to comment on the situation and we will update if we receive a response.
As I said last time, we reported this issue when filing a lawsuit. , Tesla could possibly have avoided this whole situation by improving communication with the affected owners.
Tesla had to be clear, first of all, the reason for the upgrade and what they were doing to bring the range back to those people.  But reporting on this issue was still poor, and now some owners are clearly disappointed enough to take legal action and petition NGTSA to consider the issue.
Now it begs the question: Was anyone reporting this issue bad because of the sheer incompetence on this front, or was Tesla really trying to cover up a deeper problem with package damage?
As a rule, I always go nuts for malice, but I have to say that in this case, there are some strange things, such as Tesla first talking about an upgrade that "protects" the battery.
We have been covering this situation for some time, and I often say that Tesla is unfairly targeting state regulators. more than other car makers, I think this issue is really worth considering.
I would like to hear more from the affected owners.
