General Motors is asking its Chevrolet Volt customers to return their vehicles to dealers so they can make repairs that will lower the risk of battery fires. The announcement comes after an investigation into a battery fire that consumed three vehicles at the National Highway Traffic Safety Administration (NHTSA) test facility. Follow-up tests to simulate the incident resulted in two out of three vehicles catching fire. GM and federal safety officials believe that the fires were caused by coolant leaking from damaged plastic casing around the batteries after a side-impact collisions. That coolant caused an electrical short, which sparked battery fires seven days to three weeks after the crashes.

Dealers will add steel plates around the Volt battery that will spread the force of a crash over a larger surface area. Tests carried out by GM and the government have shown that the repairs prevent battery damage and coolant leaks.

Honda has announced that they will be offering extended warranty on some 2006-2011 Honda Civic Hybrid vehicles, due to small cracks that could develop in the gas tanks. According to Honda, the cracks are not a safety problem because the potential fuel leak is very small, and comes from the top area of the tank, by the fuel filler, where there is no ignition source nearby. The driver may smell gas vapors and in rare instances may see a small amount of fuel spilled on the ground. The problem is more likely to occur in states known for very hot weather.

In order to promote consumer confidence, the automaker sent a letter to owners informing them of the extended warranty of 10 years or 120,000 miles from the time the vehicle was new. Honda has also reported the problem to the National Highway Traffic Safety Administration (NHTSA), where it is being reviewed.

Ford has announced a recall for certain 2010-2011 Ford Fusion and 2010-2011 Mercury Milan vehicles equipped with 17 inch steel wheels. The recall comes after a National Highway Traffic Safety Administration (NHTSA) investigation in January, where customers complained of cracking wheel studs on their low mileage vehicles. Ford said drivers could experience vehicle vibration leading to the wheel separating from the vehicle completely. Owners wanting more information on the recall can contact the Ford customer relationship center at 1-866-436-7332.

The National Highway Traffic Safety Administration (NHTSA) has opened an investigation into General Motors electric hybrid vehicle, the Chevrolet Volt. The investigation comes after a battery fire consumed three vehicles at their test facility, two weeks after performing side impact and rollover tests. Follow-up tests to simulate the incident resulted in two out of three vehicles resulting in a thermal reaction within the battery. According to the NHTSA there have been no reports of real world crashes resulting in fire.

GM has assured customers the the Chevy Volt’s fire risk after an accident is lower than any standard gas engine vehicles. The company said that the vehicles OnStar safety system notifies the company of any crashes involving a Chevy Volt and a team is dispatched within 48 hours to drain the battery. GM has offered to buy back vehicles or offer loaner cars at the customers request. If the investigation should lead to a recall, over 6,000 Volts could be affected.

A National Highway Traffic Safety Administration (NHTSA) investigation into GMC’s 2007-2008 Saturn Aura has been extended to include the 2005-2008 Pontiac G6 and the 2004-2008 Chevrolet Malibu. The NHTSA said the protective jacket around cables connecting the floor shifter lever to the transmission can become damaged from regular use. The cables could corrode and eventually weaken giving drivers inaccurate transmission readings. There have been seven reports of crashes caused by the problem, with one involving injuries. According to GM the problem affects mainly models with four-speed transmissions, the Malibu and G6 have similar shift systems as the Saturn Aura, but the problem happens far less frequently on those cars.

The National Highway Traffic Safety Administration’s (NHTSA) has launched an investigation into some 2007-2008 BMW Mini Cooper S vehicles after receiving twelve complaints of engine fires, including five which resulted in a total vehicle loss. Eight of the complaints alleged the the fires started while the vehicles were parked with the ignition off. Because the complaints have significantly increased in the last year, the Office of Defect Investigation (ODI) has decided to open a preliminary evaluation to assess the cause, scope and frequency of the alleged defect.

Owners of some Nissan trucks and sport utility vehicles (SUV) are urging the National Highway Traffic Safety Administration (NHTSA) to open an investigation for transmission problems. Reports filed with the NHTSA alleged that an internal crack on the oil cooler tube in some Pathfinders, Frontiers and Xterras, could force coolant into the transmission causing transmission failure. Last October, Nissan extended the warranty on radiators of 2005-2010 Frontiers, Pathfinders, and Exterras to eight years or 80, 000 miles, but under the extended warranty, Nissan did not have to cover vehicles bought used. Owners feel that Nissan extended the warranty on these vehicles, knowing they would surpass 80,000 miles before having problems with the transmission. They want Nissan to issue a recall to all owners and reimburse those who have already paid for transmission repairs.

The National Highway Traffic Safety Administration (NHTSA) has opened an investigation into some 2009 Mazda CX-9 sport utility vehicles (SUV) after reports of a high number of warranty claims for servicing brakes. Reports found that the high number of warranty claims on brakes was due to an internal brake fluid leak from the master cylinder into the vacuum booster. Drivers reported reduced brake effectiveness and extended stopping distances. A preliminary evaluation has been opened to assess the scope, frequency and safety consequences of the alleged defect. If the investigation should lead to a recall, about 40,000 vehicles could be affected.
