Battery contact flutters?!?

[IolaniRWD]

Over the past week my 2014 model S developed an odd noise under heavy acceleration that sounds like a balloon losing its air. I took it to my local SC and they said it was battery contact flutters and that the sound was “normal” unless a warning sign is prompts me otherwise. After a bit of protest they finally decided to fix it under warranty. I have since scoured the web and can not find anything on this issue.

Has anyone experienced this and or had their car serviced for battery contact replacement?

Early S 85 packs were known for bad contactors.. my sub 18k VIN had them replaced at ~30k miles ..since that early period up to late 2013 I have not read about these anymore

I have a late 14 S60.

How involved was the repair?

Battery pack has to be disassembled to replace so they give u a loaner pack ..my pack was with Tesla for over three months lol

Yup, had the contactors replaced after a warning message showed up on my 100D. The balloon noise showed up a few weeks after the message but only intermittently. If you’re already hearing the noise I’d speculate the system is either not sensing the fault or the older cars cannot detect it prior to failure.

Ok so this seems like it is a known thing then. Thanks for all the feedback. They said they would get me the contacts in a couple of days.

my wifes 85 has a loud squeal under hard acceleration. SC said it was normal and will not do anything.

It just can’t be considered a normal sound when it appears out of the blue. I would take it to another SC.

If the car is not operating as it did when it was when it left the factory it has a fault..period.

i gave up on arguing with them on it to be honest. Noise is the only issue.

If my 2016 Lexus GS350 has an odd squeak Lexus drops everything to make sure it is right. I honestly wish Toyota was focused on ev’s instead of this hydrogen excursion. I love tesla as a brand and the mission that they are on, but with the cost of these cars passing the price of a house in some parts of the country it is unacceptable for them to not offer Toyota levels of service. I can accept that the car will not be perfect, but it should be serviced in a way that is befitting of its cost.
