  1. Someday the Takata Recalls will end. Today is not that day.

    Toyota has recalled the passenger-side inflators in 1.7 million vehicles across North America.

    The airbags currently in the vehicles have metal inflators that contain ammonium nitrate without a drying agent added to protect the chemical from moisture. The moisture can destabilize the ammonium nitrate and turn the metal inflator into a grenade full of shrapnel.

    The affected vehicles include the 2010-2016 4Runner, 2010-2013 Corolla, 2010-2013 Matrix, and 2011-2014 Sienna. Toyota plans on sending out recall notices towards the end of January.

  2. Toyota is recalling 65,000 vehicles to replace the front passenger airbag inflators … again.

    Although the previous recall used new replacement Takata airbag inflators, this latest recall will use inflators supplied by a company other than Takata. Those previous replacements were still using ammonium nitrate, a propellant that breaks down and explodes unpredictably when exposed to humidity and moisture.

    Takata's inflators has been a long-running nightmare for millions of owners, hopefully this is the last time you'll have to bring your car in for service related to these exploding chunks of metal.

  3. Toyota has blamed a musty A/C smell on microbes [i.e., mold] growing o the evaporator surface and now a lawsuit wants them to do something about it.

    The plaintiffs claim the vehicles have defective heating, ventilation and air conditioning (HVAC) systems that cause smells and health problems from mold that collects on the evaporators. Numerous complaints have allegedly been filed with the government, Toyota and Lexus dealerships nationwide since at least 1999.

    This isn't the first time Toyota has been sued for musty A/C units.

  8. When Toyota switched away from using plastic or glass-based inulation in favor of soy, it invited in some very unwelcome Toyota loyalisits.

    According to the plaintiff, she learned the hard way about the soy wiring when her Avalon wouldn't start and a look under the hood showed wires chewed, so she had the car towed to a dealer. Toyota told her rodents had caused the damage and it would be no problem to repair the problems as long as she could cough up $6,000 to cover the bill.

    The soy-based wiring is allegedly attracting in rodents, who love to chew it up and use it for nesting material. The lawsuit, Heidi Browder vs. Toyota Motor Corporation, et al. follows a similar lawsuit filed against Honda earlier this year.
