passenger safety restraint system light came on, Tesla says to fix needs to install OCS filter module and replace existing OCS sensor because its not compatible with existing OCS sensor…cost is $806….there are no broken parts in my car. according to Teslas service bulletin Sep 21, 2020 this problem is caused by electrical interference in the seat harness causing the airbag restrain system message on screen due to faulty design…..Tesla says i need to pay for it because car is out of warranty, i say its a faulty design and they have to fix free. this should be a recall because Tesla is aware of many of same problems that make the airbag inoperable. from the bulletin ‘On some Model 3 and Model Y vehicles, the Occupant Classification System (OCS) signal might be affected by electrical interference in the seat harness, causing the airbag indicator to display on the touchscreen.’ Tesla has been aware of the problem for 4 years at least.
