The modern car interface can do everything from making a dinner reservation to reading your text messages. In order to do this, an array of knobs and buttons are needed on the dashboard making the use of the system much more confusing. Sam Grobart, the Times’ personal technology editor, shows us three different interface systems that are trying to solve this problem. He test drives the Acura ZDX, Ford Focus, and the Audi A8 and finds that making our lives easier can often be frustrating.

Toyota has announced a recall on over 300,000 sport utility vehicles (SUV’s) for issues with the airbag sensors that could lead to an unexpected airbag deployment. The problem is being blamed on the two airbag sensors that detect a vehicles roll angle. If both airbags fail after an airbag system check, the airbags and seat belt pretensioners could be triggered. A Toyota spokesman said that there have been reports of injury when the airbag deployed unexpectedly.

The recall involves about 200,000 2007-2008 RAV4 and almost 100,000 2008 Highlander and Highlander HV SUV’s sold in the United States. Owners will receive a recall notice starting in May, where Toyota dealers will replace the sensors free of charge.

Italian motorcycle manufacturer MV Agusta (MVA) is recalling over two hundred 2010 F4 Motorcycles. According to a report filed with the National Highway Traffic Safety Administration (NHTSA), the upper fixture points of the sub frame may not be strong enough and could lead to frame cracks and instability of the vehicle. A reinforcement support kit will be installed by dealers free of charge.

This is the second recall for this motorcycle in the past year. Last June MVA recalled almost seventy 2010 MV Agusta F4 super bikes for a faulty air filter frame that may become loose, allowing material to enter the system. This debris could damage the assembly causing the motor to seize.

Owners wanting more information on either recall can contact MV Agusta at 1-215-830-3300, or the NHTSA’s vehicle safety hot line at 1-888-327-4236 (TTY 1-800-424-9153).

Disruption in the auto industry because of the earthquake and tsunami in Japan last month have been minimal so far, but the continued aftershocks and impending nuclear meltdown causing roaming power shortages is starting to take it’s toll. Shortages of vehicles built in Japan are starting to be noticed around the world, and the lack of parts is making it difficult for other auto manufacturers to run their assembly lines. Auto analysts predict that Japans auto industry may not hit it’s full manufacturing potential until late this summer. This uncertainly has suppliers, automakers and dealers scrambling.

Car buyers are already having difficulty finding models they want in certain colors, and auto plant workers are expecting they will soon be told to stay home. The complexity of the auto supply chain shows just how vulnerable the industry can be. With over 3,000 parts going into a single car or truck, one missing part means the vehicle cannot be built. Customers not only notice auto shortages, but rising prices, especially on fuel efficient hybrids as gas prices rise.

IHS Automotive predicts that one-third of daily global automotive production will be cut because of supply chain disruptions. That means about 5 million vehicles worldwide won’t be built, out of the 72 million vehicles planned for production in 2011. In the U.S., some car manufacturers are considering shifting part manufacturing operations to local companies, but stringent safety requirements and exacting high tech specifications will limit a company’s flexibility. For now car executives are allocating certain parts to build the more popular and profitable vehicles.

Scheduled to take effect in December, California lawmakers will no longer be provided with a state purchased car, but instead will be given a monthly transportation allowance of $300 a month. According to the California Citizens Compensation Commission, the group responsible for setting state officials’ salaries and benefits, this change will cut the lawmakers’ transportation costs in half, saving the state of California over $2.3 million over the next five years.

The salary for California legislators is one of the highest in the nation even after salaries and benefits were cut in 2009. The panel decided not to cut lawmakers’ salaries again but said it may revisit the issue if Governor Jerry Brown cuts paychecks for other state workers to help reduce the budget deficit.

Senate leader Darrell Steinberg (D-Sacramento) said the move makes it harder for lawmakers to travel to and in their districts to connect with constituents. He feels the arguments for cutting legislative salaries and benefits have gone from being balanced, rational and a reflection of our economic times to simply trying to make a political point.

ford f150 airbag recallThe National Highway Traffic Safety Administration (NHTSA) began an investigation into Ford’s 2004-2006 F-150 trucks last September, which ended in a recall of about 140,000 trucks. The problem was being blamed on an improperly installed wire in the steering column that could chaff and short out. The result was an illuminated seat belt lamp and the potential that the airbag could deploy without warning.

Under pressure from the NHTSA, Ford will be expanding the recall to include almost 1.2 million 2004-2006 Ford F-150 trucks and some 2006 Lincoln Mark LT vehicles. Owners wanting more information can contact the Ford Motor Company customer relationship center at 1-866-436-7332.

Mercedes Benz has announced a recall that could affect the safety of passengers riding in the second row seating of their 2008-2011 Dodge Sprinter 2500 and 3500 vehicles. According to the recall, the safety belts in these vehicles may not lock as required and the assembly loop may not perform to minimum force requirements. During an accident, the passengers could be left unrestrained resulting in injury or death.

Mercedes Benz will inspect and replace any seat belts that have been found to be unsafe. Owners wanting more information on this recall can contact Mercedes Benz at 843-695-5000.

With rising fuel costs, many consumers are turning to diesel vehicles for their better fuel economy. Most people who operate and maintain diesel engines are familiar with a black material seen in fuel filters or at the bottom of the tank, but many don’t realize that it is a growing “algae”. This organism inside the tank will lead to poor combustion, carbon buildup, and could end up costing the owner of the vehicle large amounts of money.

The algae is the result old fuel, and while the problem is often found in boat engines, automobiles are not immune. So what can be done to prevent the problem? There are additives you can use, but if it is not caught soon enough, it can still end up being costly to the consumer. Your best line of defense is being educated about the problem, and keeping up with regular maintenance.
