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.

Common Nissan Maxima vs. Subaru Legacy breakdowns

The Nissan Maxima and Subaru Legacy are both popular sedans. Similarities can be seen in price, styling, and performance. What are some common repair problems seen in each model? When do they occur and how much do they cost to fix? What about how to pay for car repairs? Let's find out. Check Engine Light Both Maxima and Legacy owners dread the appearance of this little light. In the Nissan, it's most likely a failed ignition coil. This part transforms the car battery voltage into a higher voltage required for starting. This problem appears more often in Maximas with over 140,000 miles. The cost to replace the ignition coil runs around $400, parts and labor. The check engine light on the Subaru Legacy is more often due to a failed oxygen sensor. The O2 sensor measures the oxygen level in the exhaust and can affect fuel consumption. This part fails more frequently in models with over 110,000 miles. The repair costs around $200. Legacy Sound System Problems It's not uncommon for the Legacy to have sound system failures at 140,000 miles or more. The speakers might not work or only function intermittently. Hitting a bump might also cause the radio to shut off. Repair costs here can vary, but the typical charge is around $600. Nissan Check Engine Light Part 2 The Nissan check engine light also may appear due to oil leaking from the camshaft position sensor. Difficulty with stalling and acceleration might occur as well. The repair costs around $250 and is more frequent in models with over 104,000 miles. Big-Ticket Items Some repairs are especially costly. In Maximas with over 120,000 miles, the power steering pump may begin to malfunction. This produces a clunking or knocking sound when driving over uneven terrain. Steering might be affected with abnormal noises heard when turning the steering wheel. A Nissan Maxima power steering pump replacement costs around $1,250, parts and labor. Now, if you begin to feel your Legacy vibrating or shuddering at around 116,000 miles, it may be a transmission problem. It's more noticeable when the car shifts gears. Legacy transmission repair can be expensive, costing up to $2,000 or more. Even more costly is a Subaru Legacy head gasket failure, seen more often at 110,000 miles or more. AC malfunction, fluid leaks, and engine overheating can occur when the head gasket fails. The repair costs are around $3,000.

2015 Nissan Murano could have been a lot more boring to look at

When it debuted at the 2014 New York Auto Show, the third-generation Nissan Murano wowed us more than just about any other car on hand (that's sort of why we handed it an Editors' Choice for the NYIAS). It's sharp, aggressive design was a dramatic departure from the smoother styling of the second-gen CUV, although it wasn't too polarizing. Most importantly, though, it was a vehicle with actual design presence - you want to see it from every angle, all of which draw your eye with something new.
Of course, settling on the design for a new vehicle is far from a straightforward process. While a design might take shape on a designer's drafting table, there are a huge number of steps it needs to get through before making it to an auto show stage or to your local dealer. According to Nissan engineer Chris Reed, those steps very nearly curtailed the Murano's design before the first die was even cast.
Reed has a full account of this sharp design's trials and tribulations in a must-read story from Ward's.
