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.

Toyota and Lexus recalling 235,000 hybrid CUVs and sedans over separate issues

When it rains, it pours. Toyota has announced a pair of separate but voluntary North America recalls covering approximately 235,000 vehicles built between 2006 and 2011. The larger of the two recalls targets Toyota's hybridized crossovers, the Lexus RX400h and Toyota Highlander Hybrid. 133,000 units, including 2006-2010 Highlander and 2006-2008 RX crossovers are covered in the campaign. The other recall affects 102,000 IS350 sedans, IS350C convertibles and GS350 sedans built between 2006 and 2011.
With the CUVs, the faults in the parallel circuits of the transistors can cause heat damage in the inverter assembly, triggering an abundance of warning lamps and sending the vehicle into limp mode. The Lexus sedans are being recalled due to loose bolts on the variable valve timing controller. Detected by unusual underhood sounds on startup, the issue can cause the engine to stop while driving. The inverter issue is also triggering similar recalls in Japan and Europe.
At the moment, it's unclear if any of these issues have caused any crashes or injuries. Toyota says it plans to notify owners of the recall via snail mail. Additional information for owners can be found on the recall sites for Toyota and Lexus or by calling Toyota's customer service line, at 1-800-331-4331.

Toyota Recalling 1.67 Million Vehicles Worldwide

UPDATE: Toyota is now announcing specifically which models are covered under its fuel pipe recall in the US. The company is repairing about 423,000 Lexus models that include the 2007-2010 LS, 2006-2011 GS, 2006-2011 IS, 2010 IS C and 2008-2010 IS-F. The automaker says that it isn't aware of any fires, crashes, injuries or fatalities caused by this problem. According to Toyota, the recall is because it's possible for the fuel delivery pipes and the fuel pressure sensor to form a bad seal with the gasket between them because of a protective coating protecting against corrosion on the pipes. It's possible for this to eventually cause a fuel leak, and obviously in a hot engine bay that's a potential fire risk. To fix the problem, dealers will replace the gasket and repair the gasket seating surface between the fuel delivery pipe and the fuel pressure sensor. The company will begin notifying owners soon. You can find the official press release, below. Toyota is issuing three separate recalls covering 1.67 million vehicles worldwide with most of those models in Japan. It looks like the campaigns' impact on the US may be smaller, though. According to Reuters, Toyota isn't aware of any accidents, injuries or fatalities affecting the models. Some yet-unnamed Lexus models might also be affected. The largest of the campaigns does not currently affect any US-market vehicles. About 802,000 units of the Toyota Crown Majesta, Crown, Noah and Voxy in Japan are being repaired to replace a seal that could leak in the brake master cylinder. Those already leaking get a new brake booster, as well, according to Reuters. The only recall currently believed to affect the US is due to a problem covering approximately 759,000 vehicles with 423,000 of them here. The repair is to fix a faulty fuel delivery pipe that could cause a fire if the fuel leaks out. Unfortunately, we don't know which models it covers. Autoblog spoke to Toyota spokesperson Mona Richard and was told the information was still "under embargo." When exactly that embargo will lift isn't yet known, but we're on the case. Finally, Toyota is recalling 190,000 Corolla Rumion and Auris models in Japan for a faulty evaporative emission control unit. Autoblog is in contact with Toyota, and we'll update this story as soon as we know more about its affect on the US market.
