Re: Leaking master brake cylinder, 2011 Nissan LEAF

Wed Jan 13, 2016 11:12 am

Five years is probably stretching it but I feel that every three years is just fine... I've done mine once in the five years I have owned it and no problems... You can always use a voltmeter test and/or test strip if unsure...

I'm thinking I will this time (for the first time in 5 years), but maybe I shouldn't since I wouldn't want them to mess up something that's been working perfectly.

I had EXACTLY this problem on my 2011 Leaf. It was detected a couple of months back when the car was around 48 months and 35,000 miles (so over the 36 month warranty, but under the 36,000 mile warranty).

I'll be keeping an eye out to see if this eventually becomes widespread and Nissan has to fix it (and reimburse me since I already paid).

There is one very important thing for you to do: Call Nissan USA (not your local dealership) and request "assistance". Basically you're saying "come on guys, be nice about this". In my case Nissan USA covered half the cost of the part, saving me $800-900. I still didn't appreciate the $1500 expense, but it was better than $2400. Also, I found out after the fact that the local dealer has some say in how much assistance you get, so if you can go thru the dealer you purchased the car from, they might feel more inclined to help you out since they've made a nice profit from you already.

Ask your dealer for the phone number for Nissan USA.

If you run into trouble or don't get assistance similar to what I did, contact me and I'll give you details from my case you can cite to them.

Good luck!

Yes, sometimes Nissan is willing to help cover part of the total repair cost via goodwill.

Nissan used to list some of their warranty extensions on specific systems of specific cars at http://nissanassist.com/web/, but it seems that site is quite bare now, for whatever reason. For a flavor, see https://web.archive.org/web/20130503003 ... php?menu=1 or https://web.archive.org/web/20150912013 ... t.com/web/ (you may need to use Chrome and/or disable Javascript in your browser).

In the case of my mother's Altima Hybrid which unfortunately has a known problem of getting carboned up in certain cases (there's a TSB on it), When she was out of powertrain warranty, she hit the symptoms (CEL). Supposedly, the DTCs and diagnosis meant that she needed a new cylinder head. :shock: (TSB mentions that too.) Dealer (i don't like their service dept much, I'd have rather gone to one I like better) was able to get Nissan to cover the part but not the labor cost.

Unfortunately, the repair bill was still pretty high. IIRC, it was on the order of $2K.

'19 Bolt Premier
'13 Leaf SV w/premium package (owned)
'13 Leaf SV w/QC + LED & premium packages (lease over, car returned)

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

Now, if we could get them help those who need a new battery pack outside of capacity warranty.

I bought a used 2012 leaf a couple of months ago. It ended up having a leaking master brake cylinder also. In hindsight, I think that's why the previous owner sold the car.

Once the brake fluid got low enough, the red and yellow warning lights went on along with another brake light on the dashboard. Refilling the brake fluid temporarily made the problem go away. When the fluid was low, leafspy pro reported 2 DTCs: C1155 (brake fluid low) and C1A70 (brake control system).

I took it to the dealer, and they diagnosed that the master brake cylinder was leaking. They wanted $2800 to fix it. That price is ridiculous for a leaking master cylinder. It cost about $700 to fix in my old honda accord.

I was determined to avoid the dealership as much as possible. I called about 8 different mechanics. About flat out wouldn't work on a Leaf. Some of them said they wouldn't replace it because they didn't have the software to bleed the abs system. Two of them said they could try, but the only place they could get the part from was the dealership, they wouldn't accept customer supplied parts, and the dealership suggested price for the part was $1900.

I ended up taking it to Eschen Automotive in Bellevue, WA. He accepted customer supplied parts, and I got lucky and found a new one on ebay for $230.

After installing it he said the brakes kept acting like the were not bled, even though he followed the procedure in the leaf service manual. After numerous calls to Nissan he found out that the intelligent brake controller has to be reprogrammed after it is installed. In the service manual, the reprogramming is called stroke sensor "0" point relearning. Without that, the brakes have similar symptoms to a bubble in the air line:
* pulsating feedback in the peddle
* antilock brake buzzing
* the peddle would easily go all the way to the floor, then push back

He ended up towing the car to the dealership and had them reprogram it.

The overall price, including the part from ebay, the towing fee, and the dealership reprogramming fee, was $1200. So I still managed to save money compared to the dealership quote.

I'm in a similar situation my 2014 has 27K miles on it in good shape otherwise, but now they tell me the master cylinder is leaking even though no check engine or warning lights are showing in the dash and no malfunctions as far as I can tell. They want 2,700 (about 1/3 the value of the car) to replace it. I applied for assistance but was denied. Not happy. There's so many better electric options coming in the near future. SELL YOUR OLDER LEAFS ASAP!!!

No symptoms whatsoever, the mechanic at the dealership reported the issue after an inspection. I've been back and forth with Nissan Leaf "customer service" for about 6 weeks now and they have been very vague and unhelpful about the entire process. They offered me no financial assistance unfortunately so weighing my options.
