  2. Oil Sludge in Toyota Engines

    Toyota settled a class-action engine-sludge suit in 2007 that covered an estimated 2.5-million Toyota and Lexus vehicles made between 1997 and 2002. In that case, Toyota agreed to repair 'sludged-up' engines for up to eight years from the t…

  3. Rodents Chew Soy-Coated Wires

    Somewhere in the mid-2000's there was an industry-wide push by automakers to replace plastic and glass-based wiring insulation with a more eco-friendly soy-based coating. It's biodegradable, commendable, and a complete disaster for owners. …

  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. 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.

  3. 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.

  4. This just in from the team at Toyota: sensors work much better when they're connected during manufacturing.

    Toyota says federal safety standards require a vehicle to activate a warning light if there is a drop in the brake fluid level. However, the automaker says there is a possibility the wire harness that attaches to the brake fluid reservoir sensor was never connected during manufacturing.

    In other news: the sun is hot, traffic is the worst, and I can't believe this actually went unchecked. There's no word on when the recall will begin.

  5. A minor label issue is about to become a major pain in the butt for 2,500 Toyota and Scion owners.

    Why do automakers bother with recalls about stickers? Because of federal law. Based on federal regulations, a load carrying modification label must be added to a vehicle if weight exceeding the lesser of 1.5 percent of 100 pounds is added to a vehicle between final vehicle certification and the first retail sale of the vehicle. Any corrected values must be accurate to within 1 percent of the actual added weight.

What Owners Say About Their Highlander

Hands-Free Calls Are Unusable Due to Echo Defect

When speaking to someone on the phone using the bluetooth connection in the car, the person you're speaking with hears their own voice echo back to them. I drive often for work and am frequently on the phone. It's extremely annoying for whomever you're speaking with on the phone.

Hands-Free Calls Are Unusable Due to Echo Defect

The Bluetooth in this car for phone calls is unusable. The caller on the other end says it echoes awful and I have to call them using the speaker on my phone. I have read TONS of postings about this online - no one seems to know how to fix it but a lot of people have it. I have tried all the posted suggestions but nothing fixes it.
