WASHINGTON — The National Highway Traffic Safety Administration opened an investigation into an estimated 134,989 2001-'02 Toyota Sequoia SUVs after 135 consumer complaints of steering and braking problems.
"Consumers allege incidents of unexpected vehicle stability control activations while driving at various speeds, resulting in automatic application of braking force to the left or right front wheel and unexpected steering pull in the direction of the brake application," NHTSA said in its problem description.
About half of the complaints indicate that a faulty yaw sensor was diagnosed as the cause of the problem.
"Approximately 60 percent reported a vehicle pull to the right at highway speeds," NHTSA said. "Many of the complaints allege experiencing multiple incidents, with some involving little to no pull lasting several seconds and others involving greater pull for short duration, frequently described as feeling like a 'jerk' to the steering wheel."
There are two crashes and five injuries linked to the probe.
A Toyota spokeswoman did not respond immediately to a query from Edmunds regarding the investigation.
Federal safety regulators opened a "preliminary evaluation" into yaw rate sensor malfunction in the 2001-'02 Sequoia. Such an action sometimes precedes a vehicle recall.
Edmunds says: Owners of these vehicles will have to wait for federal safety regulators to finish their work before taking any action. But if you have an immediate concern, it's best to contact your Toyota dealer now.
