Federal regulators have launched an inquiry into older Toyota Corolla models that can reportedly accelerate suddenly while at low speeds and cause collisions.

Not yet a formal investigation, the National Highway Traffic Safety Administration inquiry includes around 1.69 million Corollas from the 2006-'10 model years, the Associated Press reported.

Safety regulators have discovered 141 consumer complaints about the issue, including a case where an owner said a Corolla surged unexpectedly at low speeds several times, the brakes failing to stop the car and causing it to collide with a parked vehicle on June 8.

Other than that petition, which was filed on Sept. 11, no accidents or injuries have been reported in connection with the problem.

The reported low-speed acceleration issue is similar to a problem related to a Toyota recall from around five years ago, Bloomberg News reported. The Japanese automaker recalled 10 million vehicles in 2009 and 2010 for unintended acceleration problems.

Toyota agreed to pay a $1.2 billion penalty in March following a criminal probe from the Justice Department that found that Toyota executives had been covering information related to the unexpected-acceleration cases. The penalty marked the largest such settlement ever paid by an automaker in the U.S.
