Toyota now admits there are problems with the anti-lock brake system on its new 2010 Prius hybrid. The company is not issuing a recall, nor giving owners of the car guidance on what to do with the vehicle. And they are not offering details on the exact nature of the problem. The story of this new defect began breaking Wednesday with word Japanese officials had demanded an investigation after 14 complaints of partial brake failure on the top-selling hybrid. American safety regulators acknowledged 100 similar complaints in the U.S.
It is the latest blemish to Toyota’s once bullet-proof reputation for quality, and getting ahead of potential safety defects. Consumer Reports Magazine’s Chief of Automotive Testing, David Champion, told NBC’s Today Show, “the brakes don’t actually fail. It”s this momentary (Gasp!) when you don’t think they’ll work and then they do work. Not a big safety (threat) but a bit scary.”
Complaints suggest the braking hesitation could be as long as one second. Yet even a one second delay in braking can make a huge difference in the likelihood and severity of an accident. A car travelling 30 miles per hour covers 45 feet per second. A speed of 70 miles an hour converts to 105 feet per second. Put another way: a once second delay in braking will add 105 feet to the stopping distance you need to avoid an accident in an emergency.
If it’s your car with brake hesitation, it’s more than just “a bit scary.”
Toyota officials say a recall is possible but gave a muddy answer when pressed on the likelihood, telling Bloomberg News, “the possibility of a recall is not zero.” Huh? Perhaps the urgency was lost in translation, but the response sounds not only dismissive, but confusing.
This kind of mushy guidance is not helping Toyota’s image at a time when there are questions from Main St. to Capitol Hill on whether the company responded rapidly enough to issues of unintended acceleration and whether it informed the public in a timely fashion.
A Toyota spokesperson told an impromptu news conference, the Prius brake problem was identified in December, and a fix was supplied at the factory level. The company insists any 2010 Prius produced since late January should be fine.
But once again, the delay in notifying the public is raising questions on whether Toyota is covering up. Here’s the timeline:
August 2009: Japanese safety officials order Toyota to investigate braking issues with its hybrids.
Nov.-Dec. 2009: Braking complaints from Toyota dealers and consumer complaints filed with U.S./Japanese safety agencies spike. The company identifies a software problem with the mini-computer controlling the vehicle’s transition from hydraulic braking to regenerative braking.
Late Jan. 2010: Engineers re-write the software in the braking computer and begin producing Prius models with modified computer programming.
Feb. 4 2010: After 5 months of investigation, testing, identification, and correction, the company publicly admits the problem.
The company could certainly have released a safety advisory in December once the problem was verified and it’s source identified. And yet again, the factories received a warning and fix before consumers. In fact, according to the Wall St. Journal, Toyota still doesn’t know how it will re-program computers in cars already on the road.
Company officials say this potential recall may also affect owners of the Lexus HS250h Hybrid Luxury Sedan.
