Smart car model under investigation bursts into flames on Highway 417

A Swiss woman who arrived in Ottawa in August to study English had one of the most terrifying experiences of her life on the road last week.

Aurlie Rossier, 34, was alone and heading west on Highway 417 near Bronsonlast Wednesday whenthe interior of the 2008 Smart Fortwo she was driving suddenly filled with smoke.

"I couldn't see the road anymore. I couldn't breathe," said Rossier, who spoke with CBCin French.

In a panic, Rossierpulled over to the side of the road, opened the door and quickly got out. Another driver stopped to help and urged her to get away from the vehicle.

Moments later the car was engulfed in flames.

"To see a car burned like this, it was really crazy for me," Rossier said. "I was really, really scared."

As the flames shot high into the air, Rossiersaid she saw the smoke change colour from white, to grey, to black, and heard the sound of windows shattering from the heat.

Smart car fires being investigated in the U.S.

Ottawa Fire Services got its first calls about the fire at approximately 12:19 p.m., according to spokesperson Danielle Cardinal, with witnesses reportinga fire at the rear of the vehicle.

The cause of the fire has not been investigated, and why the carburned is a mystery to Rossier. She said she was smoking a cigarette while driving, but hadn't dropped it,and was adamant that dropped cigarette ash could not explain why the car would fill with thick smoke "at a snap of the fingers."

Rossier is not alone in her experience. The U.S. National Highway Traffic Safety Administration is investigating several unexplained fires in Smart cars.

The U.S. investigation involves the 2008 and 2009 Smart Fortwo Coupe and Smart FortwoCabrio. The"preliminary evaluation" began last December with an investigation of eight complaints of allegedengine compartment fires that occurred while driving or shortly after engine shutdown.

In Smart cars, the engine is located at the back of the vehicle.

Analysis has now identified 27 incidents of open flame fires originating in the engine compartments of the vehicles.

Investigators have also examined data on fire-related insurance claims. That analysis revealed that the 2008 Smart Fortwo"had a significantly higher claim frequency than its peers," and also that there was a "sharp increase" in claims in 2015.

Vehicle investigations in the U.S. are complex, and this one is now at a stage called"engineering analysis." After that analysis is complete, and if evidence of a safety-related defect is found, authorities couldrecommend a recall of the vehicles.

Other Smart car fires reported in Canada

Transport Canada told CBC last Friday it was aware of only one fire in a 2008 Smart vehicle, andthe fire was determined not to have been caused bya safety defect.A spokesperson declined to provide details about the cause of the fire or its location "due to privacy issues."

However, CBC found another mysterious Smart car fire in eastern Ontario.

In November 2010, Marion Wyatt was asleep with her husband at their home in Brockville when they were awakened by asound they later surmised was caused by the tires exploding on their 2008 Smart Fortwo.

"The car was completely engulfed," said Wyatt. "Flames shot higher than the house."

Fortunately for the couple, the car was not inside their garage, so damage to the house was minimal.

"The car itself literally melted into the driveway," said Wyatt.

Police investigated the incident, Wyatt said, but did not discover what caused the fire, which occurred about 12 hours after the car had last been driven.The family also reported the fire to Mercedes-Benz, who Wyatt said "were kind of surprised," butdidn't follow up with herafter that initial call.

Wyatt said she's unaware of any investigation by Transport Canada into the fire, or ofanyone referring the incident to the departmentfor investigation.

Ottawa Smart car fire not being investigated

In Canada, potentially dangerous vehicle defects are investigated by Transport Canada, but so far, no one appears to be pursuing what happened to the SmartCar Rossierwas driving.

Rossierhad borrowed the car from her friend Aaron Matharu, who told CBC it belonged to his parents and was bought used about five years ago. After the fire, he said, he called customer service at Mercedes-Benzto inform it of the location of the car so itcould investigate.

"They were in total denial, [saying]that they'd never heard of such [an]occurrence and this was the first time," said Matharu, who discovered for himself the U.S. investigation of the 2008 Smart Fortwo.

The insurance company was similarly disengaged, Matharu said, because the vehicle was not covered for fire damage. The company did not say anything about referring the car fire to Transport Canada, but Matharu said he would make a report himself.

CBC contactedMercedes-Benz Canada requesting an interview about the car fire in Ottawa as well as the investigation in the U.S., but received only a statement.

"The safety of our customers is our primary concern and our colleagues in the U.S. continue to fully co-operate with NHTSA in its inquiry and support all investigations to their full extent."

Potential defects frequently not investigated

A consumer watchdog for drivers said potentially serious defects often go unreported in Canada.

Consumers in the U.S. are well aware of who to call, but people in Canadadon't know where to complainif they suspect a safety defect in their vehicle has caused property damage, said George Iny, director of the Automobile Protection Association.

In some cases, Iny said, insurance companies make settlements with the car manufacturerinstead of reporting incidents to Transport Canada.

"If they can get some money from the car maker, they'll agree to a hush-hush deal," said Iny, who believes that insurers should be required by lawto make a report if they have any reason to suspect a safety defect.

Reports of even one or two fires in Smart cars in Canada are alarming and worthy of investigation, Iny said.

"The Smart is small and it's made of plastic. So when it catches fire, the event is over pretty quickly," Iny said. "A fire spreads very quickly inside a vehicle, and you always havebarely enough time to get out before the vehicle is in flames. But we're wondering if the risk here might be even greater."
