Volkswagen defends safety record following complaints of power loss

Volkswagen Australia says it has no plans to recall vehicles, despite recent complaints about some models suddenly decelerating.

A coronial investigation was held this week into the death Melissa Ryan, who was killed when her Volkswagen Golf was hit from behind by a truck on the Monash Freeway in 2011.

According to media reports, the truck driver and Ms Ryan's family said the car dramatically slowed before the crash.

The investigation sparked complaints by other owners.

But Volkswagen Australia has defended the safety of its cars, saying there is no evidence to suggest "vehicle fault was involved in [Melissa Ryan's] crash".

"At this time we do not plan to announce a recall. Any recalls are conducted in accordance with the Consumer Product Safety Recall Guidelines issued by the Australian Competition and Consumer Commission," Volkswagen said in a statement.

It also says while rapid deceleration is not a common issue with its cars, the 'limp mode' function is not unique to Volkswagen vehicles.

The 'limp mode' function partially cuts power to the engine in the event of a problem to prevent further damage to the engine.

The case has led to a raft of Volkswagen owners coming forward to complain about problems with their cars.

"I was coming home on the Great Ocean Road and it just stopped in the middle of the road. Luckily I was going up a hill and there was a bit of a shoulder and I could pull off," one caller told the ABC.

Others Volkswagen drivers had similar experiences.

"It is not news to me, it used to be particularly bad when stationary and a couple of times my wife had it cut out on her while she was driving along," another caller said.

The Department of Infrastructure and Transport, which advises the ACCC on recalls, has begun an investigation into the matter.

"The department... is liaising closely with Volkswagen Australia," a spokesman said.

"Consumers suspecting a fault with their vehicle should report this to their manufacturer or dealer. Consumers can also report concerns to the department."
