As Toyota faced a third congressional hearing on its massive safety recall Tuesday, the Japanese automaker promised free maintenance to owners in an effort to win back consumer confidence.

Current Toyota, Lexus or Scion owners will receive two years of free car service under the offer. Toyota is also offering zero percent financing on nearly 80 percent of its models.

Meanwhile, the Transportation Department released a new report connecting 52 deaths with Toyota's acceleration problems stemming from sticky gas pedals.

Many lawmakers want to find a legislative fix to ensure the safety lapses don't happen again.

"As a part of our investigation and review, we are looking at the possibility of recommending the brake override system in all manufactured automobiles," said Transportation Secretary Ray LaHood.

Toyota says it will install the brake override systems in most of its new vehicles. The system would override the accelerator if the gas and brake pedals are pushed at the same time.

Some 8.5 million cars and trucks worldwide have been recalled as a result of the safety issue.
