Opel Ampera delayed over Chevy Volt battery fears

Automotive News reports Opel is delaying delivery of its Ampera extended-range hybrid to customers. The plug-in gas-electric hatchbacks have already arrived at dealers across Europe, but the automaker wants to ensure the vehicles' batteries are safe even in the event of an accident. The delay comes on the heels of a National Highway Traffic Safety Administration evaluation which saw its Chevrolet Volt twin catch fire three weeks after a series of crash tests. Since the Volt and Ampera are mechanically identical, Opel says that it wants to set up a process to deal with the batteries to make sure they're safe.

Both the Volt and the Ampera are assembled at the General Motors plant in Hamtramck, Michigan, and both make use of lithium-ion batteries to power their electric motors. GM has offered to buy back any Chevrolet Volt models from owners concerned about the safety of their vehicle, but few have taken them up on the offer. The company is currently working on a solution to the fire issue, and the U.S. government is investigating why it took NHTSA so long to bring the battery pack problem to light.

Chevy Volt battery fix may cost $1,000 per car, will hang on to top IIHS rating

Spontaneous combustion concerns weeks after a crash may prompt General Motors to spend about $1,000 per Chevrolet Volt to fix, according to a report from Reuters. The proposed fixes, which would cost a total of $9 million, would likely include reinforcements around vulnerable areas of the car's battery pack, lamination of electric circuitry and better protection for the coolant system to stop leaks.

After a severe crash that causes damage to the Volt's battery pack, coolant can leak out, and if the battery is not discharged, a fire may start. The National Highway Traffic Safety Administration discovered the fire danger this past summer when one of its crashed Volts caught fire three weeks after testing. Two more batteries later caught fire when put through simulated crash testing by NHTSA.

Despite the fire risks, both NHTSA and the Insurance Institute for Highway Safety have said they have no plans to change their safety ratings for the Volt. Both organizations gave Chevy's electric car top marks for safety after initial crash testing.

GM has repeatedly said that the Volt is safe to drive and poses no immediate risk of fire after an accident. Yesterday, Transportation Secretary Ray LaHood echoed that sentiment. Buyers have been offered loaner cars while the automaker investigates a solution and has vowed to buy back Volts from any owners who no longer want the car due to safety concerns. So far, a "couple dozen" Volt owners have taken GM up on the offer.
