General Motors has recalled 2.7 million vehicles for safety issues like faulty brake lights. GM recorded the most number of recalled vehicles from January to mid-May this year compared to the previous six years.

The latest addition of 2.7 million recalled vehicles in the U.S. pushed GM's total numbers to 11.2 million. It is the highest number of recalls made by the automaker to date. Mid-sized cars from models 2004 to 2012 are reported to have brake lights and failing ignition switches.

GM knew about the brake light problems early in 2008. In the same year, GM also issued a technical service bulletin that only required dealers to fix the problem when the car owners became aware of it. The public said GM's service bulletin posed dangers and problems for the drivers' safety. It might cause drivers to unknowingly drive a car with defective functions, leading to more potentially road-related accidents.

Since the announcement of the recalls, there had been reported 13 deaths linked to defective ignition switches. Chief Executive Officer Mary Barra communicated with the engineering department to investigate the problem.

Jeff Boyer, GM vice president for global vehicle safety, said the recent recall has made GM to evaluate every part of its business. As a part of the company's goals to provide safety and concern for their customers, Boyer pointed out to the largest number of recalls they made recently for the first half of the year.

Senator Clare McCaskill, who oversees a Senate subcommittee about GM's handling of the ignition switch problem, cited the recent recalls are vital on pressuring GM to be transparent in fixing its vehicles issues.

"Documents filed with the National Highway Traffic Safety Administration show that neither the company nor the government sought a recall to fix the brake light issue despite 1,300 consumer complaints and more than 14,000 warranty claims as of February of last year," Huffington Post reported.

The investigations initiated recently on the ignition and brake light problems influenced GM's decision to recall its cars.

As regards to the recent recalls, GM said it will also fix potential issues with the headlamps, power brakes and windshield wipers. Boyer said the company will expedite solutions to any new issues that may arise in their vehicles.
