    There are several threads about this, but now that the Model X 5-seaters are hitting the summer heat for the first time since being delivered, many are questioning the decision by Tesla to eliminate the rear HVAC fan.

    Tesla needs to realize if they made the proper decision to remove the 2nd fan for effective 2nd row cooling, possibly consider adding it back.

    Personally, living in Texas and being a fan of not sweating for me or my passengers, I am resigned to adding full thermal-blocking tint and closing the front vents if necessary, pre-cooling when possible, but what bladeless 12 volt fan will match the interior?

    What Say You 5-Seat owners who have hot +/- humid summers???

    Didn't vote as a non-owner (yet), but would be happy to vote and select 'happy to pay part of the 6/7 seat charge for the same HVAC system'.

    Let me explain. We bought our 5 seater BEFORE any were available but were able to test drive a 6 seater which has great A/C. When we received it, we didn't notice the difference until one of our unseasonably hot days in florida during December. I was in the back and started feeling sick because it was hot in the rear seats. Since then, I've taken the vehicle into the service center 3 times. The last time they took the vehicle apart and as always say, "it's working as designed." Well whoever designed it should have left the rear seats out of it and made it into a van. The rear a/c is anemic and even with the front a/c going at full blast, it doesn't shoot much flow. The most airflow comes from the front pushing to the back, not the vents in the back.

    DO NOT BUY A 5-SEATER. $120,000 cars shouldn't have this problem.

    Gotcha. If even the 2nd row is bad, that's a different issue. I believe most of the general conversation was on the 'cargo space' for dogs and the like. Hate to waste space/money on 6 seats, leave two folded down all the time, etc. But if it's really that bad.... <sigh>

    Appreciate the info.

    Remember that Tesla made a statement at the time, much quoted here, that the five-seater A/C was tested sufficient for the back too... much was made of this assurance on TMC too.

    Maybe this quote could help you guys with a remedy?

    Here is the Tesla quote being discussed:

    Flat Fold second row now available.

    Inadequate design if it has to depend on front row passengers enduring an artic blast, in order for second or cargo areas to be comfortable.

    Driving back from San Diego yesterday, and I called SvC on the spot to point out that the outdoor temp registered 73 degrees and the cargo area was 91 degrees. I folded down the second row for my dog to scoot closer to the front and have chilled air. SvC scheduled me for an immediate appt next week. Stay tuned.

    Sorry about your woes and thank you for the data point. Great to have someone post numbers. Do you recall the outside weather?

    Typical San Diego blue sky, a few passing clouds and a light breeze maybe 5 knots.

    If you read this and another TMC thread, plus one on Tesla.com, you will see the concern is all about the 2nd row passengers, and not the rear cargo area.

    Would be great if some enterprising five-seater owners would put temperature meters on first and second rows as well as the trunk and monitor.

    I am really interested to see what they say about the reduced airflow from the B-pillar vents when fan is on max. Others have been told it was working per specs.

    Show them that in order for the airflow to be equal to a 6/7-seater on max, 2 of the 4 front vents need to be closed. I used a wind meter, but just a hand of face will reveal the differences and the inadequacies of the airflow on a seated passenger.

    Although my 4-legged kids prefer to lay down close to the front row, they will still be as impacted as a human passenger.

    In my Cayenne and 6-seater, their hair can be seen "blowing in the wind", but not in a 5-seater.

    Well, as I mentioned, it's not just temperature, but airflow and circulation especially in a hot and humid cabin.
    This the effectiveness of an overhead fan in your home, airflow promotes skin cooling,

    Understood. And your measurements pointed this air moving effect out greatly.

    It would still be interesting to see the relative temperatures front to back.

    I came across this post from the legendary Bonnie, from back in Nov '16.
    Those of us aware of the limited airflow will disagree with this assessment, however, she may be correct given much cooling time and the same A/C compressor... but not accounting for airflow and passenger satisfaction.

    The more I "obsess" over this issue, the less hopeful I am and may decide to change my 5-seat order to a 6-seater, which is really unsatisfying for a vehicle costing over $110K.

    @essmd Well, we have come to know how much we can believe Tesla's statements on controversial topics.

    We simply can not take them at face value.

    The AP publicity vs. reality has been much discussed. P85D HP of course too. And then there is the P85DL, P90DL and P100D power limiters thread where Tesla promised to remove the limits and make things right... and then instead went onto limit all cars. Yes. (Pack Performance and Launch Mode Limits)

    It has gotten to the point that people on TMC actually ridicule other people for "not doing their research" if they have taken Tesla at their word and believed Tesla.

    To clarify, I was only sharing a communication from Tesla that I received.

    To further clarify, my adult son started laughing when he saw me referred to as 'legendary'. He would disagree, it appears. :)

    Hey Fury,
    Can you tell me what they told you? I get pretty anal when it comes to making purchases and especially one that is SOOO expensive. I expect it to be damn near perfect. I haven't received a response yet from the regional manager, but I'd like to have as much ammo as possible.

    I'm pretty upset that i wasn't told that there would only be one A/C unit on the 5 seater. The irony is that I have a 2015 f150 that also only has one A/C unit and it will blast you with the rear vents.
