    Range Loss Over Time, What Can Be Expected, Efficiency, How to Maintain Battery Health

    Asked Tesla Service about an undiagnosed rolling resistance problem, and they wrote, "A rolling resistance issue is unlikely. The potential suspects would be alignment (I’ve performed an automated alignment analysis that reviews average steering angles to determine if steering is compensating...

    Final post on this issue. Wish I'd discovered this article before deciding to purchase a Tesla. Posting for the benefit of others for whom range is important in their purchase decision process: Tesla Fails To Meet EPA Range With All Its Cars In Edmunds' Tests Article details how Tesla...

    AlanSubie4Life and MP3Mike: Really appreciate your replies. You guys are informative and kind, the latter being rare online when seeking info on some forums. Tire pressure was 44 psi front, 43 psi rear. Yes to aero wheels. Trees were not showing lots of wind (eg. swaying, leaf movement)...

    Here's a link to the LCD photos showing departure range, %, and at the end of each leg: 2021 M3 LR Austin-Columbus TX - Austin 2-21-21 I'm upset at Tesla. They put 353 miles of range at the forefront of their advertising, and in online chats with Tesla employees pre-sale they wrote 353 miles...

    Range Loss Over Time, What Can Be Expected, Efficiency, How to Maintain Battery Health

    I think overall vehicle performance is fine. But had I known range was so much lower than EPA, I would have waited until the technology improved. The Teslike.com shows a 2019 M3 LR with 310 EPA range achieving 277 miles of range at 75 mph, or 89%. With our 2021 M3 LR, that would be 315 miles...

    Range Loss Over Time, What Can Be Expected, Efficiency, How to Maintain Battery Health

    Drive slower than the posted speed limit? Not a reasonable request of a normal consumer. If Tesla vehicles only achieve 70% of EPA range, this should be knowledge easily available to potential consumers. I spent 2 months researching Tesla M3, and range was a top issue for me just as it is for...

    OK. Here's the range update I promised. Planned a drive from Austin to Columbus (end of Hwy 71 where it meets IH10) and back without stopping except to take photos of display. Vehicle was never in "park", only "hold" and only for a few seconds.. Had to wait until weather improved in Texas...

    When you say miles instead of %, do you mean on the top of the screen the battery display which can toggle between range remaining and percentage of battery left, or the Trip A or B trip meter lower on the screen?

    Range Loss Over Time, What Can Be Expected, Efficiency, How to Maintain Battery Health

    Really appreciate your explanation. What are "stickies" where I would find more info? The big issue for me is how far can I drive on longer trips, and is my battery only capable of 63 kWh of charge? As an experiment, I will drive 100 miles rt in one day after a full charge and report back. My...

    Agreed! BTW, Sentry Mode is off to save power per Tesla's suggestion. Here's the kicker. Went to www.tesla.com and began a Model 3 LR chat with a Tesla rep. Did this before buying, and also talked with local reps at the service location here in Austin. Asked the online rep if 353 miles is a...

    Range Loss Over Time, What Can Be Expected, Efficiency, How to Maintain Battery Health

    Confused. "Since Last Charge" is pretty specific language. Why would idle data be excluded? Even if it is, idle power loss is quite minimal in these vehicle, I believe. I did to a 130 mile r/t on state highways recently (65 mph with some stop lights) in one day to go hiking. The vehicle was...

    353 miles. The Tesla manager told me to ignore the 353 mile display, but later in the conversation stated the fact the vehicle displays 353 miles of range at 100% charge indicates it is fully charged. Crux of problem, I continue to believe, is that at 100% fully charged the vehicle only has 63...

    Posted this to another user. Apologies if it's a mistake to post it here, but would appreciate your opinion. I'm averaging around 240 Wh/mile over time. Using your calculations, the vehicle should easily drive over 300 miles using 99% charge capacity. Again, think the issue is my vehicle...

    So here's my info. I live in Austin, TX. I've reported this issue twice to Tesla service in the past month. They asked me to charge to 100% and discharge to as much as possible. I charged to 100% and over 5 days depleted the car to 1%. Vehicle drove 258.5 miles, used 63 kWh of power, and...

    I have a 2021 Tesla Model 3 Long Range (refresh model) with EPA of 353 miles. After notifying Tesla my range is in the 250-270 mile range on a full charge, they asked me to fully charge and deplete. I still only got 258.5 miles of range when fully charging to 100% and depleting to 1%. Anyone...
