Feds investigating 2010-11 Mazda CX-9 CUVs over braking issues

The National Highway Traffic Safety Administration is investigating 62,000, 2010-2011 Mazda CX-9 models over brake problems. The government safety watchdog says it has received seven complaints of an observed loss of power braking power to stop the crossover, according to the The Detroit News.
The NHTSA complaints say that the problem causes a hard pedal, increased braking effort and reduced braking effectiveness. Some complaints allege that they hear a hissing noise during braking similar to the sound of air leaving the tires. No injuries or crashes have been reported.
"As always, we are fully cooperating with NHTSA on their investigation. We cannot comment further at this time," said Mazda spokesperson Tamara Mlynarczyk to The Detroit News.

Crash test videos show how rust compromises safety

These recently released Swedish videos serve as a reminder that rust isn't just a cosmetic flaw, when it comes to cars. The insurance company Folksam and the homeowner organization Villaagarnas Riksforbund gathered examples of two relatively popular, but by now rusty cars, and then performed crash tests with them at the Thatcham Research facility in Britain. The results are sobering. The rustier cars chosen for the tests were first-generation Mazda6s, cars that have a reputation for early-onset rust in salty surroundings, such as the Nordic countries in Europe or the Salt Belt in the U.S. The cars in the other end of the spectrum were fifth-generation Volkswagen Golfs, which thanks to their body treatment only really start to show rust at over ten years old. But rust isn't just on the surface, it goes bone deep. While the Mazda did decently well in Euro NCAP testing as a new car, there's now a 20 percent higher risk of death in the 2003-2008 Mazda due to the degradation of its bodyshell. In the rusty car, the chassis rail separates from the floor, the footwell ruptures, the sill gives way, the seat mountings move and the dummy's head hits the B-pillar; all important failures, despite Thatcham saying the cars actually performed better in the crashes than they expected with all the rust. But still, the corroded structure isn't able to transmit loads in the way it was originally designed to do. This content is hosted by a third party.

The Golf does significantly better — despite rust flakes flying when the Golf hits the wall — as the years have only caused it to lose a single point. An important thing to remember is that the cars aren't tested in comparison to corresponding new, 2018 cars: the tests are in reference to the crashworthiness standards in place when they were new. The cars' airbags inflate like they were supposed to, but on the Mazda the dummy's head bottoms out the airbag due to the car's structure failing, meaning the airbag cannot perform as designed. Driven cautiously, an older car is still mostly fine for driving around. But tests like these remind us that it's not enough that a car runs and drives, if the body has turned into Swedish knackebrod. And if you repair the visible rust and the structure underneath remains as compromised as ever, there's an ugly truth under all the bondo. Perhaps it isn't such a bad idea to have yearly roadworthiness inspections.

2020 Mazda CX-30 small crossover lands an IIHS Top Safety Pick rating

The 2020 Mazda CX-30 has come out of the gate swinging on the safety front, earning the Insurance Institute for Highway Safety (IIHS) Top Safety Pick award in its first year on the market.  Mazda's new baby crossover earned a "Good" rating in all six of the Institute's crashworthiness categories (driver-side small overlap front, passenger-side small overlap front, moderate overlap front, side, roof strength and head restraint) and its accident avoidance system was rated "Superior." Sadly, only one set of available headlights was rated "Acceptable" or better, which kept the CX-30 out of the running for the coveted Top Safety Pick+ award. The best-rated lamps available on the CX-30 are actually those that come standard. The curve-adaptive units offered as an optional upgrade were rated "Poor" due to excessive glare. For 2020, IIHS made the guidelines for earning Top Safety Pick and Top Safety Pick+ awards even more stringent. Up until 2019, cars needed only to earn an "Acceptable" rating in the passenger-side small overlap test to qualify for a Top Safety Pick. For 2020, that has been raised to "Good."   The bigger challenge for many OEMs will be headlights. To earn Top Safety Pick+, a vehicle cannot be sold with any headlight configuration that does not earn at least an "Acceptable" rating.    So far, fewer than two dozen 2020-model-year vehicles for sale in the U.S. have met the criteria for Top Safety Pick+; roughly half again as many qualify for the lesser award. In coming years, the Institute is expected to add even more conditions, especially in the realms of accident avoidance and pedestrian safety.
