From this assembly video, looks like the cooling channels are in the bottom of the battery tray, and look fairly large.
They look fairly large to me as well. If there's a way to monitor the temperatures of the individual modules, that would provide additional assurance that a channel isn't plugged.

The compressor is clearly integral to the i3 drivetrain and IMO, BMW should warranty it as part of the drive train. Also it seems like BMW should have employed better engineering in terms of filters, sensors, etc., to mitigate the metal shavings risk.

Yes - and since the battery cooling channels are in parallel, a system flush may not be adequate, as flow will take always take the path of least resistance. If one or more of the channels is partially blocked, they won't flush out, only the 'most open' channel(s) will get flow through them.

Definitely! Since this seems to be a common thing, when an AC compressor in an i3 fails, and it can basically total the car, really something that should have been addressed in the design of the system.

This makes me so sad! i3 is built to last, at least that is what i believed but this completely changes that.

My car had trouble with compressor and it started making grinding mechanical sound.. Dealership replaced the compressor under warranty but they did not discharge/recharge freon. Not sure how they pulled that off. But i feel fortunate that this happened while car is still under warranty

How do you know that they didn't discharge the system? EPA law requires them to reclaim all refrigerant out of a system before making repairs, so the equipment is mandatory at every repair shop to remove the refrigerant, filter it, and return it to the car once the fix is completed and cooling system holds a vacuum.....

I called the general manager at the dealer last Friday (June 28), Chandler BMW. It was a most cordial call on both ends with Shane expressing disbelief, but a promise to throughly research my car history and whether other i3s have had this issue. I know his shop saw the same issue the week (or two) before mine and told him that. Shane promised to call BMW corporate to see if there was anything they could do to help make this right by me, and he promised to call me back on Monday or Tuesday. No return call (it is Thursday).

I called BMW customer service, which is the i-concierge customer service. I was told that if the regional service manager offered $2000 off on a new BMW, that such an offer is typically the final say from BMW on the matter. He offered to take any counter offer I wanted to make to the higher level committee, and their response would take 3-5 business days. I offered to give them an opportunity to withdraw the highly insulting offer of $2000 and make me a more reasonable offer to get me into another i3. That was rejected, and I was told to give him a dollar figure for a yes or no reply. I asked if BMW would provide me with a loaner while they deliberated. He said no, but that I could ask the dealer for that. Note that I am out $300 for the first service, and $200 for the privilege of getting a $22,300 repair quote, and have already used up the 5 days of loaner cars from the dealer for this effort. I told him no thank you, but that I would be in another manufacturer's electric vehicle within 3-5 business days.

Any recommendations on a class action law firm?

I'd go after the local dealership, since they worked on the AC system before it failed and mis-diagnosed the leak that ultimately led to the compressor failing. Odds are that their insurance will pay for the "malpractice" to settle before a trial, whereas BMW will throw a whole pack of bored corporate lawyers at a class action suit and have it dismissed after 3-5 years of stalling.....

I agree with vreihen. First, to file a class action law suit you need a large group of people who have had the same issue, and second, the only people who get anything but satisfaction out of a class action law suit are the lawyers. I'd sue the Dealer for damages. The dealer either misdiagnosed the issue, and though paid to do so, failed to make timely repairs, resulting in the damage, or they incorrectly overcharged the system or failed to add the correct freon/oil mixture to the system, resulting in the damage, or a combination of both. Check your repair bills. Do they say the repair work is warrantied for any period of time? Even if not stated on the bill, a court will likely rule that is implied. Consult an attorney, and get an idea of what this will cost you (too large an amount for small claims court) in both money and time, and determine if you want to proceed - would seem to be a pretty strong case for negligence. The Dealer may look at the cost to defend against the claim in court, and decide to fold and negotiate a settlement well before it ever gets that far. Also, you should file a complaint with the Better Business Bureau. In some areas they have quite a bit of clout.
All said, if you determine the cost to pursue the Dealer is too much, or won't be effective, if it were my car, I think I'd weigh the chance and cost of taking it to an independent AC shop, along with printouts or links from the BMW service manual for the system, and the specs for pressurizing the system, and the special freon/oil mix it takes, have them flush the system, put in that debris screen that is supposed to protect the compressor, and see if that allows a few more years of life from the car, before just dumping it for salvage.

FWIW, I would give him a dollar figure for what the current value of a similarly optioned i3 and model year (say $15k for a bare 2014) and see what happens with a possible additional condition that you would keep the car. You might also want to update your FB post with the latest; in fact, the compressor issue is currently trending in 2 posts today in the FB group, so your update would make it 3. I would also mention to iCOncierge that many people on the FB group are concerned with how BMW is treating this issue. It's possible BMW is also monitoring that FB group since they recently pointed to it in their notification about closing their iforums, so that might wake them up. Also ask to speak to "the manager" higher and higher up the chain.

I know nothing about a/c systems. Is there a filter on the i3's a/c system just prior to the compressor that can remove contaminants like metal? If not, is there such a thing that can be fitted if/when a new system is installed?
