Recently helped @mr_hyde to setup toolbox 3 to diag a 2014 MS with the most economical 1 day subscription. Seems like most first timers spend quite awhile dealing with computer IT/connection issues. 1 day subscription could even expires before even getting proper connection to the car working...

Sharing some failure mode analysis with others who has been inside the battery pack (NOTE : HV can be deadly dangerous so absolutely need to be familiar with all HV protection precautions) This is @mr_hyde car with his original post here and here. Car is 2014 MS P85D 67k miles. In Seattle...

Many people struggle with this and it is challenging. Because HV bus is basically shared by all HV devices, 1 device failure disables HV battery output. Some devices are likely not smart enough? (for example the coolant and cabin heater) to report any info to aid car's own diagnostics alerts...

Been checking service mode for [Service-Fix] alerts and sees this one. Alerts time stamps compared to google maps navigation log shows occurring during my drive. Google shows nothing on this alert code. 2013 MS85 75k miles. Original battery pack (RevB) No issues (yet haha). Sounds like there is...

This is the electric motor pump that generates the vacuum pressure for hydraulic brakes. ICE gets vacuum from engine compression cycle suction. Hybrids and EVs need to used electric motor pump. Price from Tesla is $500 as of now (Starting to be more challenging to get parts AND price quotes...

Sorting out coolant heater behavior with a fellow 2013 MS owner with gen1 DCDC in these winter months. Used scanmytesla to record 3 trips. Here is the conclusion and data Car is no hurry to warm up the cell. Regen is limited for quite while until avg cell temp reach ~18.4C which takes more than...

One of failures that can disable drivability is some failure modes from the DCDC HV clients (AC comp, coolant heater, cabin heater) These failures don't have much to do with drivability other than coolant heater to enable faster driving+charging. Tesla is being ultra safety conservative @ the...

73k miles. Won't go into drive with a bunch of error codes (looks like HV loop disabled). LDU rebuild completed ~ 2weeks ago and driven 350 miles before this problem. Error codes shows repeated attempts to connect HV (presumably to charge 12V and heat battery?) until 12V got too drained and...

I know Tesla says no need to change coolant. And the coolant doesn't see any kind of high temps like ICE. But coolant will degrade over time and become acidic and attack seals. So seem best to change it after say 10 years as my 13 MS is coming up on this and never had a full coolant flush. Drive...

13 MS 85 60k miles. Had driver front window problem starting last couple of years. Sometimes would struggle to go up, sometimes doesn't go up at all. Seems to occur more with wet weather. Since the closed window retracts and returns each time the door open/closes, driver's window motor gets the...

Understanding the Tesla Model S Performance Motor - YouTube 45min long. EV auto repair school teacher's teardown. Talks about the "ceramic" bearings, lubrication and coolant compartments/channels. Quite amazing we don't see common cross contamination issue between coolant and oil given the...

Mobile tech did steering motor bolt recall in 12/18 and random steering popping noises started after. It seems to randomly reproduce starting from standing still such as backing up and turning from parked position and doesn't necessarily depend on tight turns. Some times it would occur at the...

Every manufacturer gets this incentive regardless when they enter the market. So early entrant can't gain all the benefit of taking early risk. Once early entrant's credit runs out. It's incredibly hard to compete with a new entrant armed with $7500 credit. This affect the lower priced segment...

Just an FYI for other Model S owners. Had intermittent rotor rubbing/squealing sounds from the front passenger side at lower speeds and coming to a stop without foot on the brake. Sometimes not even regen and just cruising along. My brakes also squeal whenever applying them (Tesla says normal...

Wife is a bit freaked out but I assure her the following - Plenty of well placed superchargers along the way (I count 7) and she has the 85 - Bring home charger in case road is blocked off somewhere. Just need 110 to keep the car alive + heat - Check weather reports + road conditions the night...

Model S Proclip vent mount with Garmin attachment Proclip vent mount perfect fit over Model S vent to the left of the center display with Garmin GPS ball mount attached. Brand new condition and never used. I think was like $70 originally for both. Freeshipping in lower 48 US. List...

Wife drives the Model S to shuttle kids around and the hatch/liftgate gets used quite a bit. Don't have tech. Anyone retrofit it afterwards? Cost?

Got caught out in the snow on the eastside going from Kirkland to Sammamish. Have some big hills but fairly long so grade is not too steep and well traveled... Didn't need to stop. Car did well. Felt the rear end slip with a rhythmic pattern a few times. Feel and sound like in accordance to the...

Went to a local detailer today to inquire about paint correction (for swirls) and sealant. Below is what I learned. This location wrapped 43 Teslas last year and hundreds of cheaper detail efforts on Teslas so seems rather experienced. - I asked why my 13 year old Volvo shows no scratch at all...

Have been wondering what the Model S is costing us to operate in terms of energy consumption. Got the latest electric bill and here is a rough breakdown Average 20.4kWhr per day extra electricity use compared to last year's bill. Model S is showing about 340Whr/mile so just about 60 miles for...

Don't have tech package so using a 1+ year old Garmin (Nuvi 1450T). The Garmin frequently says it can't locate the satellite. Presumably due to the coating I've heard about on MS's windshield? iPhone/Waze doesn't report can't find satellite but would go through short periods of losing your...

Just a short trip from Redmond WA to Beaverton OR to visit the inlaws and some college campus visits for our son. Wife was stressed out about our first EV car out of town trip. I planned out things in advance and it turned out much much easier than I thought. Original Plan Redmond (Actually...

Its probably a bit early for us Model S owners to think about the worn out batteries. But there are various quotes of how battery is even worse for the environment than fossil fuel (I know its a natural scare tactic and scientifically quite hard to believe given the consequences of burning...
