  4. Rodents Chew Soy-Coated Wires

  1. A lawsuit wonders how Toyota can keep calling their bluetooth implementation "hands-free" when owners very much need to use their hands to prevent echos on each and every call.

    For years owners have complained about this issue, but Toyota's only suggestion has been to pickup the phone and turn it's volume all the way up after the call has been initiated. Oh, and also make sure the radio volume is below level 45. Sorta defeats the point, don't you think?…

  2. 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.

  3. A lawsuit says 2005-2011 4Runners weren’t properly treated to protect against corrosion.

    In May 2018, the plaintiff was driving his car on the highway when the steering wheel allegedly started vibrating so violently the 4Runner went off the road. A mechanic said the right front control arm fractured because of excessive corrosion and rust. Toyota may deny knowing about rust problems in court, but that argument should crumble even faster than their frames.

    In 2016 the automaker settled a massive corrosion lawsuit for similar model years of the Tacoma, Tundra, and Sequoia vehicles. That was the same year as a recall for 690,000 trucks with corroding rear suspension leaf springs.

  5. 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.
