Owners of 2010 RAV4s report unintended acceleration happening repeatedly, often while braking or stopped at lights. The engine revs loudly to high RPMs—sometimes over 4,000—and the car lurches forward or accelerates despite firm brake pressure. Many incidents occur within the first few thousand miles, with some happening multiple times on the same vehicle.
Owners consistently state their feet were on the brake, not the accelerator. Some say brakes become stiff or less responsive mid-incident. A few describe the vehicle continuing to accelerate even with both feet pressing the brake or after shifting to Neutral.
Critically, many owners report this failure *after* Toyota's recall repair was performed. One owner experienced it three times post-repair; another had the entire accelerator pedal replaced and still experienced the problem. Dealers frequently cannot reproduce the issue during diagnostic testing and find no problem codes. Toyota has not pinpointed a root cause in most cases. Incidents range from low-speed parking lot accelerations (4–5 mph) to highway speeds, resulting in collisions with vehicles, curbs, barriers, signs, and structures. Some owners report a single event; others document 3, 4, or 12+ occurrences. The failure is unpredictable—restarting the engine sometimes stops the surge, sometimes not.
Failure modes owners describe
Unintended acceleration during braking
Engine revs to high RPM and vehicle accelerates forward while driver applies brake pedal with normal or firm pressure. Occurs most often while approaching traffic lights, stop signs, or parked positions at low speed (5–35 mph). Driver's foot confirmed on brake, not accelerator.
When: Primarily low-speed braking scenarios; earliest reported at 6,200 miles; occurs through vehicle lifetime
Symptoms owners cite: Engine revs loudly to high RPM (often 4,000+ RPM); Vehicle lurches or surges forward despite brake application; Brake pedal may feel stiff or unresponsive; Vehicle continues to accelerate even with both feet on brake
Repairs/costs cited: Dealers unable to reproduce failure or identify root cause in most cases. Some replaced accelerator pedal assembly; some performed throttle-return spring repairs (recall 10V017000). Post-repair failures remain common.
Recalls/TSBs owners mention: Recall 10V017000 (Accelerator Pedal) performed; in some cases, floor mat replacement or removal; owners report repairs do not eliminate recurrence
Unintended acceleration when stopped or stationary
Engine surges to high idle or vehicle accelerates forward while stationary at traffic lights or stop signs with foot on brake. Vehicle may move several feet or lunge forward. Engine continues to rev even after shifting to Park or Neutral.
When: While waiting at red lights or stop signs; reported as early as 6,450 miles and continuing
Symptoms owners cite: High RPM rev while vehicle stationary with foot on brake; Vehicle lurches or moves forward against brake; Engine continues to rev even after placing car in Park; RPM spike subsides after several seconds or engine shutdown
Repairs/costs cited: No repair typically available; dealers unable to reproduce during diagnostic visit
Recalls/TSBs owners mention: Recall 10V017000 applied; no further remedy identified
Unintended acceleration while downhill or on incline
Vehicle accelerates suddenly while descending or approaching inclines with foot on brake. Owner reports one incident on freeway exit ramp while turning; another while descending canyon road at slow speed. Engine revs and vehicle accelerates despite brake application.
When: During downhill driving; one case at 5 miles, another on canyon descent
Symptoms owners cite: Sudden uncontrolled acceleration on downgrade; High engine RPM; Brake ineffective; Vehicle continues acceleration into turn or through intersection
Repairs/costs cited: No repair documented
Recalls/TSBs owners mention: Recall 10V017000 performed in at least one case; failure persisted
Unintended acceleration in Reverse
Vehicle accelerates rapidly in Reverse immediately upon shifting into Reverse, without driver applying accelerator. One case: vehicle went from 5 mph to 55 mph in Reverse. Another: vehicle instantly began reversing at high speed when shifted into Reverse.
When: Upon shifting to Reverse; reported at approximately 65,000 miles and during driveway exit at unknown mileage
Symptoms owners cite: Vehicle accelerates rapidly in Reverse without brake or accelerator pedal input; Brake pedal ineffective or unresponsive; Vehicle crashes into stationary objects (stone fixture, parking sign, tree); High speed achieved in short distance
Repairs/costs cited: No repair documented in submitted complaints
High idle or engine rev when accelerator released
Engine enters high idle state or revs loudly when driver releases accelerator pedal or approaches traffic light. Vehicle may try to lunge forward. Distinct from typical engine sound and behavior.
When: Reported early in vehicle ownership; one case at 6,200 miles
Symptoms owners cite: Engine suddenly revs to high RPM without driver input; Vehicle tries to lunge or move forward; High idle persists for several seconds; Engine may sound as if flooring accelerator
Repairs/costs cited: No repair identified; restarting engine sometimes stops condition
Recalls/TSBs owners mention: Recall 10V017000 performed; no root cause identified
Cruise control failure—inability to decelerate or stop
While cruise control is engaged at 70 mph, vehicle does not decelerate when brake pedal applied. Multiple brake applications required to finally stop vehicle.
When: Approximately 74,000 miles
Symptoms owners cite: Cruise control active at highway speed (70 mph); Brake pedal depressed but vehicle does not decelerate; Multiple brake applications required to stop; No warning lights illuminated
Repairs/costs cited: Dealer diagnosed cruise control module as damaged and needing replacement; repair not performed
Recalls/TSBs owners mention: Manufacturer notified; no assistance offered
Brake pedal becomes stiff during unintended acceleration event
During unintended acceleration, brake pedal becomes unusually stiff or harder to press, reducing driver's ability to control vehicle. One owner reported needing to lift foot and reapply brake twice to achieve stop.
When: Coincident with acceleration events; reported at ~6,450 miles and 6,598 miles
Symptoms owners cite: Brake pedal stiffness or resistance during acceleration event; Reduced brake responsiveness; Need to pump or reapply brake multiple times for vehicle to stop
Repairs/costs cited: No repair attempted; condition not reproduced by dealers
