How to fix a $4,000 hybrid battery problem with vinegar and baking soda

This is one of those 'Don't try this at home if you don't know what you're doing' DIY tales. Two weeks after imgur user "scoodidabop" bought a used Toyota Camry Hybrid with no warranty, he got the Christmas Tree dash display with warnings like "Check VSC System," "Check Hybrid System," and the Check Engine light. After some Internet sleuthing he figured it could be a faulty brake actuator, assuming the hybrid system warning was a false alarm. But it wasn't the actuator, it was the battery, a Toyota dealer telling him that his battery had "gone bad," and he'd need $4,457 to replace it. Then he had a brainstorm: it could be one of the cells that's gone bad, not the whole battery. Scoodidabop has some experience as an electrician, so he figured he could test it and replace any bad cells for about $45 apiece. He removed the battery unit from the trunk and over the course of two hours tested all 68 cells four times. He found nothing wrong. So he devised another type of test and checked every cell again. He couldn't find a problem with any of them. Turns out the problem wasn't in the cells, but with the dirty and corroded copper connectors at the ends of the high-voltage cables. He pulled the 34 connectors and their steel nuts, soaked them in vinegar, gave them a light steel wool scrub, soaked them in baking soda and water to counteract the vinegar, applied an anticorrosive and reinstalled them. That took an hour. When he replaced the battery, the warning lights had all gone out and the battery worked perfectly. Skill level: experience. Cost: less than $10. Perhaps it's time for hybrids to be able to test their own cells individually. Dealers, too.

Hydrogen stations that don't work putting a dent in H2 lifestyle

Hydrogen is the most plentiful element in the universe, but it's not abundant enough for some hydrogen fuel-cell vehicle drivers. Southern California lessees of models such as the Hyundai Tucson Fuel Cell SUV are taking to Facebook to voice their complaints about out-of-order fuel cell stations, Green Car Reports says. In many cases, the lack of hydrogen supply has made the cars effectively undriveable. For Tucson Fuel Cell owners, the hydrogen is supposed to be free and unlimited, but Hyundai doesn't manage the stations. One Orange County lessee of a Tucson fuel-cell vehicle hasn't driven the car for over a month because the trio of nearby stations are out of commission. Additionally, some of the stations that do work can only provide about a half-tank worth of hydrogen, once again putting a crimp the driving range of the hydrogen car. California is home to 10 of the dozen public hydrogen refueling stations in the country (there's one each in Connecticut and South Carolina), according to US Department of Energy figures. These sorts of challenges can't help Hyundai's hydrogen efforts. Last month, it was reported that Hyundai has sold fewer than 300 fuel cell vehicles worldwide during the past three years, including about 70 through the first five months of this year. The South Korea-based automaker has said it wants to sell 1,000 fuel-cell vehicles globally by the end of 2015. Fuel-cell drivers and advocates alike are hoping that Toyota will change the game when its Mirai hydrogen vehicles start hitting California roads later this year. Toyota confirmed in May that Mirai US sales would start in October in eight California dealerships. The Northeast is on tap for 2016. Related Video:

IIHS: Drivers safer than passengers in frontal crash test

The Insurance Institute for Highway Safety introduced a small overlap frontal crash test in 2012 that replicates what happens when the front corner of a car impacts another object. In the test, vehicles travel at a speed of 40 mph toward a five-foot-tall barrier with 25 percent of the total width of the car striking the barrier on the driver side. One would assume that vehicles with good small overlap front ratings would protect the driver and the passenger equally. But a recent study from the IIHS proves that passengers aren't as protected as drivers. The IIHS conducted the test on seven small SUVs with good driver-side small overlap ratings and only one of the vehicles, the 2016 Hyundai Tucson, performed well enough to be given a good rating. The other SUVs performance ranged from poor to acceptable. After reviewing the results of the test, the IIHS is deliberating whether it should institute a passenger-side rating as part of its Top Safety Pick criteria. "This is an important aspect of occupant protection that needs more attention," states Becky Mueller, lead author of the study and an IIHS senior research engineer. "More than 1,600 right-front passengers died in frontal crashes in 2014." Since the small overlap front test was introduced, 13 automakers have made structural changes to 97 vehicles with roughly three-quarters earning a good rating after the adjustments. The IIHS' test for frontal ratings is completed with a dummy in the driver's seat and with a barrier overlapping the driver's side. Which makes sense, as passengers aren't always riding in a vehicle. "It's not surprising that automakers would focus their initial efforts to improve small overlap protection on the side of the vehicle that we conduct the tests on," states David Zuby, IIHS executive vice president and chief research officer. "In fact, we encouraged them to do that in the short term if it mean they could quickly make driver-side improvements to more vehicles. As time goes by, though, we would hope they ensure similar levels of protection on both sides." As the IIHS' test revealed, there's a massive difference in safety between the two front seats. Increase passenger safety, according to Mueller, would require automakers to strengthen the occupant compartment by using a different type of material or by making it thicker.
