Fisker Automotive is alerting drivers of certain 2012 Fisker Karma vehicles, built between June 15, 2011 to July 9,2012, about an electrical problem in the low temperature cooling fan. According to Fisker, a short in the fan could ignite the fan housing, shroud and surrounding components, causing a vehicle fire. Owners will be asked to bring in their vehicles to the nearest Fisker dealership to replace both low temperature cooling fans with improved fans. Owners wanting more information about the problem can contact Fisker consumer affairs at 1-855-575-7577, option 2.

Ford Invests In Hybrid And Electric Technology
Ford is working hard to become the leader in hybrid and electric vehicles (EV) as they invest over $130 million to build an advanced electrification center in Dearborn, Michigan. The facility will employ approximately 1,000 engineers and will accelerate the companies EV development capabilities. The company hopes to top the market by launching five new electric or hybrid vehicles this year alone. Ford has just recently started developing their own transmission technology which will be built on the same platform as their mainstream gasoline engines. This has allowed them to cut the costs by 30% and will also allow the company to build vehicles according to consumer demand. Amy Machesney, the C-Max marketing manager said Ford feels it now has a product capable of competing with Toyota, and we are confident our EV and hybrid vehicles are comparable to the Prius.
Mitsubishi Airbag Sensor Problem
Mitsubishi is asking owners of certain 2012 i-MEV electric vehicles to bring in their cars to correct a problem that could prevent their airbags from deploying properly. According to Mitsubishi, an incompatibility between the air bag sensor and the self diagnostic software, could deactivate the front and side airbag system. During an accident, the airbags may fail to deploy, increasing the chance of injury. Owners of affected vehicles may notice the Supplemental Restraint System (SRS) warning lamp illuminating to alert the driver of the problem. Owners wanting more information can contact Mitsubishi at 1-800-222-0037.
Toyota Rear Suspension Problem
Toyota has announced a recall for certain 2006-2011 Toyota Rav4 and 2010 Lexus HS250H vehicles because of a problem with the rear suspension. According to the recall report, if the nuts on the rear suspension arm are improperly tightened during a wheel alignment service, the tire rod will develop movement which could lead to rust and damage to the threads. The tire rod could fail causing an abrupt change in the vehicles alignment leading to loss of vehicle control. Drivers who notice a strange noise coming from the rear of their vehicle are asked to contact their nearest dealership as soon as possible. Toyota is working on a repair for the problem and will send out notifications as soon as possible. Owners wanting more information about the problem can contact Toyota at 1-800-331-4331 or Lexus at 1-800-255-3987.
Low Gas Tax Revenue Prompts New System
Counties in the San Francisco Bay area are considering getting rid of gas taxes and switching to a vehicle miles traveled (VMT) system instead. The National Surface Transportation Infrastructure Financing Commission (NSTIFC) recommends the switch because revenue from gas taxes have declined over the years as hybrid, electric, and more fuel efficient vehicles become prevalent on roads. They say that it will “balance the costs and benefits of the surface transportation system to those who are using it”, and could also reduce traffic congestion on the roads. The proposal is one idea in long range planning, updated by the agency every four years. If the idea is accepted, it would likely not be fully imposed until 2020.
Randy Rentschler, a spokesman for the regional commission, admits that the idea could be difficult to introduce. Radical changes like this will always be opposed by certain groups, and privacy issues will be questioned as a GPS based systems would be used to log information on when and where drivers are traveling. Transit advocacy groups are encouraging the transition to a VMT system to be tested first in the Bay area where the idea will be more easily accepted and the revenue could be used to support alternative public transportation options.
Powering EVs With Lithium-Air Batteries
Consumers who are thinking of purchasing an electric car are usually deterred by the range of the lithium-ion battery used as the power source. Concerns about range, life expectancy, and the ability to find a charging station usually results in the consumer purchasing the vehicle with the technology they are familiar with, the combustion engine. Researchers are hoping to change consumers attitude toward electric vehicles with a new electrochemical cell called the lithium-air battery.
Lithium-air batteries are attractive to researchers because they rely on air as the cathode and lithium metal as the anode. This allows the battery to be lighter and can offer up to ten times more energy per density mass unit than conventional lithium-ion batteries. The first lithium-air battery was developed in the mid 1990’s but the technology still requires improvements before we can expect to see it used commercially.
- The battery requires a steady flow of oxygen to operate, so an air compressor and blower will need to be added to the system. This not only negates the weight reduced on the battery, but adds extra parts to the system.
- Lithium metal is highly flammable when exposed to water, so water vapor must be removed from the air and a water tight encasing is required.
Despite recent significant improvements in the technology, researchers say we are still 15 to 20 years from seeing it offered to the public. Once the battery has been approved a long term array of testing is required to make sure the battery can be used safely.
BMW And Toyota Share New Technologies
German automobile manufacturer BMW and Japanese automobile manufacturer Toyota have announced that they will be expanding a 2011 agreement between the two companies to share strategic technologies in four different areas. BMW and Toyota emphasized that they have no intentions of building stakes in each others companies. Both say they share the same strategic vision of sustainable individual future mobility and feel their alliance will only strengthen both companies competitive position in sustainable future technologies. The agreement includes:
- The joint development of a fuel cell system.
- The joint development of architecture and components for a future sports vehicle.
- Collaboration on power train electrification.
- Joint research and development on lightweight technologies.
The agreement will also end any further discussions of BMW working with General Motors and will eventually dissolve a joint venture with France’s PSA Peugeot Citroen to share components for hybrid cars.
Court Decision Reversed In Fuel Economy Case
A Los Angeles County judge has reversed a court decision to award a former attorney almost $10,000 over fuel economy claims for her 2006 Honda Civic. The case received national attention last year, when Heather Peters opted out of a class action settlement that would have paid Civic hybrid owners up to $200 or $1000 off the purchase of a new car. Honda appealed the court decision, and Los Angeles County Superior Court Judge Dudley W. Gray reversed the small-claims judgment last Thursday.
According to Gray, the automaker was within its rights to advertise the Environmental Protection Agency (EPA) fuel economy ratings for the vehicle and rejects the idea that it was misleading. He added that Federal regulations control the fuel economy ratings posted on vehicles, but they are only there for comparison among vehicles and don’t take into account conditions that could affect fuel economy such as how people drive and the condition of their vehicle.
Peters lawsuit has prompted almost 40 other Civic owners to seek similar recourse. Honda has already won 18 of the suits and has lost one case, in Santa Barbara, involving a 2003 Civic hybrid. Peters said that although she is disappointed with the final ruling, she is glad she raised awareness that Honda is no longer the great brand it used to be.
