The National Highway Traffic Safety Administration has closed an investigation into 100,491 2007-'11 Toyota Camry Hybrid vehicles for power braking concerns.

The investigation was closed after Toyota said it would offer extended warranty coverage to consumers, according to the NHTSA.

Federal safety regulators said they reviewed at least 734 complaints and 864 warranty claims for braking issues in the affected hybrid vehicles.

The automaker will extend warranty coverage for the brake actuator assembly and skid control unit/brake pedal stroke sensor in 2007-'11 Camry Hybrid cars, NHTSA confirmed.

Toyota's warranty enhancement program covers repairs related to two separate conditions. The conditions include internal malfunctions of the brake actuator assembly, and overly sensitive monitoring logic for the brake pedal stroke sensor.

Once the primary coverage period ends, secondary coverage is provided for 150,000 miles, or 10 years from the date of first use, whichever takes place first, according to the NHTSA.

Toyota issued a service campaign back on July 10 to replace the brake reservoir tank in the 2007-'11 Camry Hybrid.

The new tank will be available until June 30, 2017 at authorized Toyota dealerships.

"Analysis of the failure data indicate that each condition provides warning prior to any reduction in power-assisted braking, with less than 10 percent of all reports and claims involving diagnostic codes or complaint narratives indicating increased braking effort or reduced brake effectiveness," NHTSA said in its summary. "In addition, most of the incidents in which reduced braking assist appears to have occurred involved operation in a reduced assist mode and not a sudden, complete loss of power-assisted braking."

Just one crash was linked to the probe, though the owner had not handled the problem for eight months, the report said.

Less than 1 percent of reports claimed a "complete loss of power-assisted braking" and "this mode requires operation for a significant period of time with multiple audible and visual warnings," NHTSA added.

Repair costs exceeded $3,000 in some cases.

If you're an owner of a 2007-'11 Toyota Camry Hybrid you should check with your local dealer regarding extended warranty coverage if you have any braking concerns.
