Tesla's Model S has been recently surrounded with controversies but still the car has topped Consumer Reports' owner satisfaction survey.

The Model S, which is the company's fully electric luxury car, is still the center of debate after three cars caught fire in separate incidents within a span of two months. Tesla is said to be investigating the fire cases.

The U.S. National Highway Traffic Safety Administration (NHTSA) also confirmed that it will investigate the fire risks from the undercarriage of the Model S striking objects.

One of the Model S caught fire on October 1 in Washington state and the other in Tennessee on November 6. Both the cars caught fire after hitting metallic road debris that damaged the battery-casing of the car.

Another Model S fire was caused in Mexico after the driver hit a concrete wall. Drivers of all the accidents escaped unhurt.

However, it seems that Model S owners are the most satisfied customers. The luxury car, which has a starting price tag of $70,000 and can also go beyond $100,000, has received an owner satisfaction score of 99 out of 100. The score is the highest the magazine has seen in many years.

"We typically find the cars that inspire the strongest consumer loyalty are those that are either fun to drive, deliver great fuel economy, are fashionably green, or envelop owners in a high-tech, luxurious driving environment. This year, the Tesla Model S all-electric luxury sports sedan, which provides all of those attributes, tops the ratings. Owners of the Tesla Model S gave it the highest owner-satisfaction score Consumer Reports has seen in years: 99 out of 100. Coincidentally, the owner-satisfaction score matches the near-perfect 99 overall test score for the Model S," notes Consumer Reports.

Even though the Model S has received high scores in the customer satisfaction survey, Tesla will want to make sure to carry on full investigations regarding its cars catching fire and hopefully, make changes to its cars to avoid any future accidents.
