What owners describe

Powertrain

Many owners of this 4Runner describe the transmission hesitating and revving before suddenly engaging when accelerating out of a turn or slow traffic. This can feel like a lurch forward after a delay, which some owners found unsettling in traffic situations.

Warning signs:
Owners notice the engine revving high while the vehicle hesitates or fails to accelerate, followed by a sudden lurch forward once gear engages.
What shops did:
Dealers ran diagnostics or reflashed the ECM, but many owners report the problem persisted or could not be diagnosed.
Mileage:
most between 5,000 and 25,000 miles, among 10 complaints that give it

“The engine revs to a high RPM as if searching for a gear and does not accelerate as commanded”

  • NHTSA 13V014000January 20133,235 vehicles

    Seats · Air bags: frontal: sensor/control module-inactive

    Southeast Toyota Distributors, LLC (SET) is recalling certain models interspersed through model years 2009 through 2013 as follows: model year 2009-2012 Tacoma, 4Runner, Camry, Camry Hybrid, Prius, and RAV4; model year 2009-2010 Avalon, FJ Cruiser, and Highlander Hybrid; model year 2010-2013 model year Corolla, Sienna and Tundra; model year 2009-2013 Highlander and Venza; model year 2012 Prius V; and model year 2010-2012 Sequoia.

This could increase the risk of personal injury during the event of a vehicle crash necessitating airbag deployment.
