Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
TSB: This bulletin includes basic procedures for inspecting and adjusting World Standard (WS) Automatic Transmission Fluid (ATF) level at normal vehicle operating temperature. Note: The following adjustment procedures are for U660E/F and U760E/F transmissions.

The failure pattern owners describe
Owners describe frightening loss-of-control events: vehicles accelerating to full throttle (above 6800 RPM) when entering traffic or merging, with brakes insufficient to slow them down and accelerator pedals stuck high. Some needed to shift into Neutral to stop. Unintended acceleration also occurs in Reverse, even with gentle pedal pressure.
Transmission troubles are widespread. On highways, cars downshift abruptly from 60 MPH to 20 MPH without warning and no trouble codes appear. The display shows "Drive" while the car behaves as if in a lower gear. Manual Sport mode sometimes won't shift, or falsely displays "Drive" while selected in "Sport." Drive engagement sometimes fails entirely—the car won't move forward despite being in Drive, though Reverse works. Vehicle rollback on inclines while in Drive happens about 40 percent of the time on mild slopes, even when transmission is engaged.
Traction control activates unexpectedly during shifting or braking with no loss of actual traction; dealers acknowledge it's common but have no fix. One owner reported brake lock sensation while attempting Reverse, with the car continuing backward regardless of gear selection. Rear differentials fail with grinding and whining noise around 70,000 miles, and some leak oil heavily at the electromagnetic coupler sub-assembly.
Across all these failures, dealers consistently cannot replicate the problems and find no diagnostic codes, leaving owners unable to get repairs despite repeated visits.
Failure modes owners describe
Unintended acceleration (forward)
Engine revs to full throttle (6800+ RPM) and vehicle accelerates without driver input, sometimes triggered during turn entry or lane changes. Brake application does not sufficiently slow the vehicle; accelerator pedal does not return to idle. Some incidents resolved by shifting to neutral; others required extended engine stop button hold. Floor mats ruled out in some cases. Toyota corporate and dealers unable to duplicate or provide remedy.
When: At traffic entry/merging; under 2 minutes of operation in one case; intermittent in others
Symptoms owners cite: Vehicle accelerates to full throttle without driver input; Engine tachometer enters red zone (above 6800 RPM); Brakes inadequate to slow vehicle; Accelerator pedal does not return to idle; Engine stop button requires extended hold to stop motor; Vehicle revs to full throttle upon restart
Repairs/costs cited: Towed to dealer; dealer unable to replicate; no repairs completed
Unintended acceleration (reverse)
Vehicle unexpectedly accelerates while in reverse, even with light pedal pressure or gentle depression of accelerator. Occurs in rainy conditions and during normal backing maneuvers. Driver able to stop vehicle in reported cases, but unpredictability presents safety hazard.
When: While backing up at low speed (5 MPH); intermittent; some instances in rainy weather
Symptoms owners cite: Unexpected acceleration while in reverse; Accelerates with light or gentle accelerator pedal pressure; No warning before acceleration
Repairs/costs cited: Vehicle not repaired; malfunction unresolved
Transmission shift logic failure (rapid downshift/false display)
Transmission exhibits rapid, unwarned downshifts from highway speeds (40–60 MPH) to very low speeds (10–20 MPH), causing sudden deceleration. Display shows 'D' (Drive) but car behaves as though in Sport mode or lower gear. Sport mode manual shifting sometimes non-responsive or displays 'D' while 'S' is selected. No trouble codes found after multiple dealer inspections. Owner resorted to manual Sport mode shifting to regain control.
When: Highway driving; intermittent; multiple occurrences over weeks
Symptoms owners cite: Rapid downshift from 60 MPH to 20 MPH without warning; Rapid downshift from 40 MPH to 10 MPH without warning; Display shows 'D' while vehicle behaves in Sport/lower gear mode; Manual shift non-responsive in Sport mode; Display shows 'D' when Sport mode ('S') selected; No trouble codes generated despite repeated occurrences
Repairs/costs cited: Dealer inspected four times; no trouble codes found; no repairs completed
Drive gear engagement failure
Vehicle will not engage Drive after shifting from Park or Neutral, despite brake applied and normal shifting procedure. Acts as if in Neutral even when selector in Drive. Reverse works normally. Problem resolves after multiple shift attempts or reversing then re-engaging Drive. Dealer unable to duplicate. High risk if occurs in freeway traffic.
When: At low speed (20–25 MPH residential); intermittent; one reported incident
Symptoms owners cite: Drive gear will not engage; car feels as if in Neutral; Brake pedal responsive but car does not move forward; Reverse gear engages and functions normally; Shifting from other gears to Drive unsuccessful on first attempts; Problem resolves after reversing then re-engaging Drive
Repairs/costs cited: Towed to dealer; dealer unable to duplicate or repair
Reverse gear engagement failure / brake lock sensation
Shift into Reverse does not engage; transmission remains unresponsive despite shifting attempts. Brakes feel locked or non-responsive. Shift to Drive does not resolve issue; vehicle continues to back up. In one case, even Neutral shift and external push ineffective. Transmission feels defective.
When: At parking/driveway; low speed; incidents at 40,000 miles and mileage unknown
Symptoms owners cite: Reverse gear does not engage; Shift into Drive does not stop backward motion; Brakes feel locked or non-responsive; Vehicle continues to back up regardless of gear selection; Transmission unresponsive to shift attempts
Reverse idle insufficiency
When backing up, idle speed is sometimes too low to propel vehicle in Reverse without additional accelerator input. Vehicle does not move despite being in Reverse. Inconsistent; does not occur every time.
When: While backing up; intermittent
Symptoms owners cite: Idle speed insufficient to move vehicle in Reverse; Vehicle does not move backward despite being in Reverse
Traction control spurious activation
Traction control light flashes or activates unexpectedly during gear shifting or brake application, regardless of road conditions. Activation lasts approximately 30 seconds before automatically deactivating. Occurs from very low mileage (100 miles). Dealer acknowledges failure is common for model type but has not developed remedy.
When: From low mileage (100 miles); intermittent; during shifting or braking
Repairs/costs cited: Dealer inspected twice; unable to duplicate or repair
Recalls/TSBs owners mention: Dealer acknowledged failure common for model type; no remedy developed
Surge forward during braking
Vehicle surges forward unexpectedly while braking at moderate speed (35–40 MPH). Surge occurs twice in succession. Brakes are applied gradually and lightly; no accelerator pedal pressure. Requires both feet pressed firmly on brake to stop vehicle. Floor mats not involved. Cause unclear—accelerator or computer malfunction suspected.
When: At intersection approach; 35–40 MPH; single incident
Symptoms owners cite: Vehicle surges forward during light braking; Surge occurs twice in quick succession; Requires full brake pressure to stop vehicle; No accelerator pedal input
Hesitation/pause after brake release during acceleration
Vehicle hesitates or momentarily pauses before accelerating after brake is released in Drive or Reverse. Hesitation intermittent and unpredictable. Dealer unable to diagnose despite inspection. Problem persists and occurs repeatedly.
When: After brake release in Drive or Reverse; low mileage (100 miles onset); current mileage 10,813
Symptoms owners cite: Hesitation when accelerating after brakes applied; Momentary pause before acceleration; Intermittent occurrence; Occurs in both Drive and Reverse
Repairs/costs cited: Dealer inspected; unable to diagnose; not repaired
Downshift surge during deceleration
When driver takes foot off accelerator at moderate speed (around 45 MPH), vehicle downshifts multiple times in sequence, causing surge deceleration until reaching 20 MPH, then coasts freely. Garage unable to diagnose or fix.
When: At 45 MPH during deceleration; intermittent
Symptoms owners cite: Rapid sequential downshifting on foot-off accelerator; Surge deceleration from 45 MPH to 20 MPH; Free coasting after downshift sequence completes
Repairs/costs cited: Garage unable to fix
Rollback on incline in Drive
Vehicle rolls backward while in Drive on inclines or hills, even when transmission is engaged. Occurs when driver releases brake at stop sign or during stopped state on slope. Happens approximately 40% of the time on mild slopes. Creates hazard of hitting vehicle behind.
When: On inclines/hills at stops; intermittent (40% of time on mild slopes)
Symptoms owners cite: Vehicle rolls backward while in Drive; Occurs on relatively mild slopes; Occurs at stops when brake is released; No accelerator input
Rear differential failure (grinding/whining noise)
Rear differential develops whining and grinding noise while driving and accelerating, progressively worsening over short time. Differential confirmed 'shot' requiring replacement. Vehicle deemed unsafe for long distances due to overheating risk. Noise emanating from rear axle.
When: At 70,000 miles; noise developed suddenly and worsened rapidly
Symptoms owners cite: Whining noise from rear axle; Grinding noise from rear axle; Noise during acceleration; Progressive worsening over short timeframe; Differential overheating risk noted
Repairs/costs cited: Rear differential replacement required
Rear differential oil leak
Oil leaks from rear differential at electromagnetic coupler sub-assembly and coupler itself. Unit heavily covered in oil. Coupler is non-serviceable; entire unit requires replacement per dealer.
When: Mileage and timing not specified
Symptoms owners cite: Oil leak from rear differential; Oil leak from electromagnetic coupler sub-assembly; Oil leak from coupler; Unit heavily soaked in oil
Repairs/costs cited: Electromagnetic coupler non-serviceable; replacement required

I put my vehicle in reverse and the brakes seemed to lock, when I put it in drive it continued to back up. No matter what gear I put it in it stayed in reverse. I was blocking a lane at the mall ,u my husband tried to push it while in neutral but he couldn't budge it, it was still in reverse. I think it has a defective transmission, and it only has 40,000 miles on it. Scary and very dangerous…
My 2009 Toyota venza with only 70,000 miles suddenly developed a whining, grinding noise while driving and accelerating. The noise was coming from the rear axle. The noise got progressively worse very quickly. After mechanical inspection I was informed that the rear differential was shot. I was also informed that the vehicle shouldn't be driven for long distances because of the potential of the…
I accelerated to make a lane change,vehicle took off to increasing acceleration I attempted to brake car would not respond. Luckily no traffic was ahead of me. Finally car managed to stop. I didn't think it would. I had to practically stand on brake pedal. I was assuming some how the cruise control was inadvertently pressed but no it was not. *tr
