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.

Scion's would-be savior C-HR spied before its Toyota rebadging

Scion is dead, but one of its future products, the C-HR concept, is still in development for launch as a Toyota. Toyota does a thorough job of hiding the C-HR's rakish shape on these test cars, but we can spot the concept's design cues. For example, the pointed nose and narrow headlights are present, and the giant box on the roof can't hide the downward arch for the coupe-like rear. The back doors on these examples look larger than before, which suggests a switch to a traditional five-door body rather than the hidden rear openings on the concept. The change would offer easier access to the backseat and make the C-HR a better competitor in the segment against vehicles like the Honda HR-V, Mazda CX-3, and Jeep Renegade. The C-HR debuted as a boldly styled three-door crossover at the 2014 Paris Motor Show. Toyota later restyled the CUV with a more angular shape and extra doors. We most recently saw the compact crossover with Scion branding at the 2015 Los Angeles Auto Show. Rumors suggest the production model's debut at the Geneva Motor Show in March, and it could arrive at dealers in the latter half of 2016. The powertrain lineup likely consists of a four-cylinder engine with a CVT and possibly a hybrid version, too. You'll also get to see the C-HR on the track because Toyota will race the crossover in the 2016 Nurburgring 24 Hours. Related Video:

Porsche takes 2016 Le Mans win on last lap, Ford grabs class victory

So far, only one Japanese manufacturer has won the 24 Hours of Le Mans endurance race. That carmaker was Mazda exactly 25 years ago with the legendary, rotary-engined 787B. This year, Toyota was amazingly close to winning with their TS 050 car, piloted by Kazuki Nakajima, and it all ended in tears on the last lap. The Toyota ran smoothly for almost 24 hours, but to lose power and stall on the pit straight with five minutes to go is nothing short of catastrophic. Still, the #5 car was able to be restarted and limped across the finish line for 45th place. Toyota's #6 car had its own set of issues, as the car gained bodywork damage and also veered off track in the hands of Kamui Kobayashi. Driven to second place, the Toyota #6 passed the finish line driven by Stephane Sarrazin. For Porsche, the win with the #2 919 Hybrid was the 18th constructor title at Le Mans 24 Hours. The car was driven by Romain Dumas, Neel Jani and Marc Lieb, and it proved to be more reliable than the #1 919 with Timo Bernhard, Mark Webber and Brendon Hartley behind the wheel. The #2 Porsche and the #5 Toyota battled for the lead throughout the day. Had the Toyota not broken down, Audi would have missed a podium finish for the first time in 18 years - a great run was ruined this year by turbo trouble in the #7 R18 e-tron Quattro driven by Lotterer-Treluyer-Fassler, and the third place was taken by the #8 Audi with Lucas Di Grassi driving.
