Re: Brakes Fail upon Powering On

Mon Oct 12, 2015 2:54 pm

My brakes started acting up today. Went to a store and returned to the Leaf and backed up. Pressure on the brake pedal didn't stop the car, scary. More pressure caused the brakes to slow down my motion and stopped it. A lot of pressure. Made and still makes a loud squawk at this point but stops the car.
Checked the brake fluid, appeared to be lower than the minimum line so went to NAPA and got a the $4 bottle of DOT brake fluid and put about 2-3 oz in the reservoir. Still makes that noise and would be considered unsafe to drive. Seemed like a lot of fluid and don't see any leaks on the ground. As the car comes to a stop after the squawks I can hear what sounds like something continuing to rotate another ten turns.
Yellow and Red caution lights are on, BRAKE light is on, Emergency brake works and releases. ABS, Traction Control light are on as is the one to the right of the ABS light.

Anyone have any ideas. My nearest Nissan dealer is 90 miles and I probably can make that without rear-ending someone, but it would help if there were a simple fix. I've tried the dealers service before but it is sparse and don't always return calls.

LSP DTC readout shows 4-5 charging related errors that have been there for 6 months. The following read Ok None: ABS,AIR BAG,BCM,BRAKE,EPS,EV/EHEV,HVAC,HV BATTERY,IPDM/E/R,METER,MOTOR CONTROL,SHIFT.

Previous comments contain excellent description of the sounds made. I use Leaf Spy Pro on an Android phone via BT.

I had exactly the same symptoms and problem went away after 3-4 days. Using LSP I also saw CAN bus errors as well as ABS and Brake controller related DTC'S. Did change 20 amp fuse related to VCM?

I think I have a similar problem.

Yesterday I trickle charged my 2015 Leaf S for about 8 hours with Leaf Spy Pro running on my phone and a bluetooth transmitter connected to the OBD port. When the car was about 70% charged, I attempted to back it out of my garage and down an inclined driveway.

It was a fast, scary blur, but I think that the brakes did nothing--I do recall a clicking or grinding sound--and I stopped the car with the parking/emergency brake. I sat there, dazed, and assumed that I hadn't actually put the car into drive mode, so I tried it again--with the same result. I was able to stop the car from rolling backwards by putting into D, but then the car continued to creep forward, and the brake pedal seemed to be ineffective. I quickly applied the parking brake and shut the car off.

At about 5AM the next day (today), I checked the car again. The following warning lights ARE on: brake warning (both "BRAKE" and the drum brake symbol with the exclamation point in the middle), ABS and the master warning lights (both red and yellow). However, Leaf Spy Pro indicates NO Diagnostic Trouble Codes.

Regardless of the outcome, I HAVE already filed a report with NHTSA at https://www-odi.nhtsa.dot.gov/VehicleComplaint/ (This could be a SERIOUS problem.)

Perhaps coincidently, my local Nissan dealer "reprogram[med the] electrically-driven intelligent brake control unit" about 5 days ago. This was per a Nissan recall, I think. (My invoice indicates "PERFORM CAMPAIGN P5327.") There is another thread for P5327: http://www.mynissanleaf.com/viewtopic.php?f=27&t=20785

This happened about 7PM on a Sunday night, so I'm waiting to call my local Nissan dealer and/or the Nissan 800 number at the start of the business day on Monday.

I just purchased one of these:

I keep it in the car should the 12V battery fail in my LEAF. Probably overkill but reading other threads about 12V battery problems, and living in a part of the country where 12V batteries last only about 3 years, I thought it was prudent.

Maybe link this new problem to this thread: http://www.mynissanleaf.com/viewtopic.php?f=27&t=20785 . I know I won't be getting this done ( until further review) :x

Exact same thing happened to me today. Started my 2013 Nissan Leaf and put it in reverse and almost immediately the car started moving back. Since my drive way has a considerable slope, the car moved fast. Brakes felt soft and no resistance. Had to slam the brakes pretty hard to the floor to get the car to stop. Turned the car off and started it back on after few mins. Still the same issue. Moved the car to Drive and it did the same thing. Slammed the brakes again hard to stop the car. Left the car there for a while and started it after an hour and everything seems normal now. Took the car to the dealer (Corona Nissan) and explained the problem. Was told the car is out warranty (39500 miles) and estimated diagnostic cost is $127. I still need to look at the warranty guide to see if this falls under Powertrain/EV system coverage.

Just the thought of my kids or someone else present around the car sent shivers. Extremely fortunate that no one else was close by.

I also noticed many owners with the same issue, but only saw 10 complaints so far for this on http://www.safercar.gov. I filed my complaint.
Anyone who had or will have an issue, please take few minutes to post your complaint on http://www.safercar.gov/ or https://www-odi.nhtsa.dot.gov/VehicleComplaint/

Did you have the 12V battery checked?
Free testing at most automotive stores.

When my 12V had a bad cell the braking was very bad once while parking.

Multiple web posts and safety post will not eliminate your risk.
Get it fixed.

My 2015 S just had the same problems as mentioned above in numerous other posts. I would not expect it to be a battery problem since the vehicle is only 2 months old. Just last Friday I had the recall performed on the vehicle the same as the person above. It is not that cold here, in fact warmer than it has been in the mornings.

Read the DTC codes

U100D 0109 ABS CAN Comm circuit
U110D 0109 ABS E-driven intelligent brake comm BRC-130
Ok None ---> AIR BAG
Ok None ---> BCM
Ok None ---> EPS
P3195 000B EV/HEV CAN Error EVC-272
U1000 000B EV/HEV Can Comm Circuit
Ok None ---> HVAC
Ok None ---> HV BATTERY
Ok None ---> IPDM E/R
Ok None ---> METER
Ok None ---> MOTOR CONTROL
Ok None ---> SHIFT

I am going to take a voltage reading of the battery after it sits for a bit because I had it running for a couple minutes. I did take a reading when it was running and found 14.5 VDC. After I shut the car off it dropped very quickly to 13.0 VDC and was still dropping when I left it. It seems maybe something is still loading it down after turning of the car. Once the dealer is open they can come pick it up and give me a loaner while they fix it. It's kinda sucky because this is the second problem I have had on this car and it only 2 months old. This one is quite dangerous as well.

I checked the car aux battery again, this time I left the meter on "min" setting and booted the vehicle up. I ran it through some forward and reversing operations with the original problem still existing. Turned the vehicle off and had a look at the meter and found the min voltage to be 12.15 VDC with average at 13.85 VDC. I would assume 12.15VDC should be adequate to operate the brake system.

Last night I gave the vehicle a good run out to pick my mother up at the ferry terminal and back to my place, it was a good 60 km round trip and used 50% battery life. I would assume a good run like that would get the battery nicely charged, but from reading another thread, apparently the battery charge is brought down to 13.1 VDC for whatever reason.

Spoke to the dealer we are having it towed to nissan
