Nissan Leaf battery cells put through torture test, live to charge again

One minor chink in the armor of the Tesla Model S is that a small number have caught fire, once their battery packs were penetrated. Nissan Leaf drivers, however, might just be able to weather such an event without an ensuing CarBQ. Our evidence for such a claim? A video that has surfaced of cells from a Leaf pack undergoing a battery of torture tests (pun somewhat-ashamedly intended). Shared by folks at the Hybrid Auto Center in Las Vegas – who offer for sale, among other things, used Leaf lithium battery modules – the footage shows salvaged cells being brutally assaulted with a screwdriver, and later, a propane torch. Granted, these tests are not the same thing as flinging a piece of metal into a working pack at 70 miles per hour, but they do claim to show that a puncture does not always equal a fire. Oh, and don't try this at home. When pierced through by the flat head tool, there is no explosion or eruption of flame. Instead, a rather modest wisp of smoke shyly emerges as the electrolyte next to the shorted area of the fully-charged foil pouch reacts with the influx of oxygen. Again and again, the blade descends, until the cell is riddled with holes. No fire. Amazingly, when connected with a voltmeter afterward there are still plenty of signs of life, and when it is charged and discharged (off-camera), it reportedly suffers only a slight loss of charge capacity. The video goes on to show another cell attacked with open flame with similar results. While the demonstration is, perhaps, somewhat crude, the message it sends is loud and clear: lithium batteries can be safe and rather robust, despite some freak accidents.

About 20k Nissan Pathfinder, Infiniti JX models recalled for potentially faulty brakes

The National Highway Traffic Safety Administration has issued a recall for the 2013 Nissan Pathfinder and 2013 Infiniti JX due to a problem with the front brakes. The problem is a result of the brake torque member (a part that attaches the brake caliper to the front suspension), which was cast improperly with a structural weakness that could possibly lead to "reduced braking, increasing the risk of a crash," according to NHTSA. How, you ask? If the part breaks, the brake caliper could move position and possibly make contact with the wheel.
Around 20,000 of these sister crossovers are being recalled, but it doesn't sound like all were equipped with the faulty component. Dealers will inspect vehicles built between December 3, 2012 and January 29, 2013, and replace components from the defective batch. The recall goes into effect next month, but until then, the official recall notice is posted below with information for how owners can contact Nissan.

2014 Nissan Leaf EVs recalled for missing welds

The Nissan Leaf has been recalled before, for problems with the passenger-side airbags. Early models of the car has also had start-up issues, but those did not lead to a recall. Today, we're learning about another problem with the world's most popular electric vehicle. In April, the National Highway Traffic Safety Administration issued a recall of a small number of 2014 model year Leaf EVs - just 211 units that were made between February 28 and March 12 of this year – and reminded the world about it this morning with a Tweet. The problem, NHTSA says, is that, "the front structural member assembly may be missing welds," and that means that the car's structural integrity could be compromised in a crash. You don't say. Starting in the middle of June, Nissan will look at the vehicles that could be missing welds and offer replacements for free. If you have a potentially affected vehicle, Nissan should be contacting you soon, or you can call the automaker at the number listed below. Report Receipt Date: APR 16, 2014 NHTSA Campaign Number: 14V192000 Component(s): Potential Number of Units Affected: 211 Manufacturer: Nissan North America, Inc. SUMMARY: Nissan North America, Inc. (Nissan) is recalling certain model year 2014 LEAF vehicles manufactured February 28, 2014, through March 12, 2014. The front structural member assembly may be missing welds, which could reduce the structural integrity of the vehicle if the vehicle is involved in a crash. As such, these vehicles fail to meet the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection," and 305, "Electric-Powered Vehicles: Electrolyte Spillage and Electrical Shock Protection." CONSEQUENCE: Missing welds may effect the vehicle's integrity in the event of a crash, increasing the risk of injury to the vehicle's occupants. REMEDY: Nissan will notify owners, and dealers will inspect to see if any of the welds are missing. Any vehicle missing welds will be replaced, free of charge. The recall is expected to begin by mid-June 2014. Owners may contact Nissan at 1-800-647-7261. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
