Dear NHTSA, I hope this message finds you well. I am writing to bring to your attention a matter of significant concern regarding water leakage in my vehicle, which I believe has the potential to compromise the safety and functionality of the car's electronic systems. I would like to submit this report to the National Highway Traffic Safety Administration (NHTSA) to ensure that appropriate…

What stands out
Of the 8 model years of Toyota Venza we track for electrical problems, this one carries the most owner complaints on file — 17.
The failure pattern owners describe
Buyer takeaway: The 2009 Venza has documented electrical gremlins affecting safety-critical systems—spontaneous starter cranking, loss of power steering and brakes, faulty seat heater fire risk, and uncontrolled liftgate descent. Get a pre-purchase inspection focusing on starter, computer diagnostics, and seat heater operation; many issues leave no codes for technicians to find.
The 2009 Venza electrical problems span multiple systems with serious safety implications. Water infiltration during rain reaches both front fenders and the panoramic roof, creating risk of computer and wiring damage. Several owners report the vehicle attempting to start on its own while parked, with the starter solenoid engaging and filling the engine compartment with electrical smoke—one incident required neighbor intervention to prevent a fire by disconnecting the battery. A recall for this defect was issued for other 2009-2011 Toyota models but inexplicably excluded the Venza.
Loss of instrument cluster display and gauges mid-drive, accompanied by loss of power steering and power brakes, has left owners without control while moving. The vehicle then refuses to start, with technicians unable to diagnose the problem—no diagnostic codes appear to guide repairs.
VSC, ABS, and brake warning lights fire up multiple times, with cruise control malfunctioning erratically. In wet weather, owners report the vehicle skids dangerously when braking. Driver's side seat heaters produce burning electrical smells and melting ECUs, with some units excluded from recall coverage. Airbag warning lights persist despite multiple sensor replacements costing thousands. Rear liftgates have descended unexpectedly on occupants, and battery drain occurs when the rear hatch is operated.

Failure modes owners describe
Water infiltration damaging electrical components
Water leaking into the vehicle through gaps at the front fenders and panoramic roof seams during rain, with potential to damage the computer system, control units, and electrical wiring.
When: During rainy season
Symptoms owners cite: Water visible leaking on both sides of front section; Water seeping through panoramic roof at rear; Concern about computer system damage
Spontaneous starter engagement and electrical fire risk
Vehicle attempting to start on its own while parked with no one inside. Solenoid mechanism connects battery to starter independently, causing engine compartment to fill with electrical smoke. Three separate incidents reported, some with immobilizer lock-up following the events.
When: While parked, unprompted. Cold weather may be a factor. Incidents January 2019, October 2019, December 2019
Symptoms owners cite: Vehicle attempts to start without key in ignition; Electrical smoke in engine compartment; Starter motor cranking on its own; Engine immobilizer activates and will not recognize keys; Clicking from starter while parked; Headlights and fan blower activate on their own
Repairs/costs cited: $672 starter replacement (one owner)
Recalls/TSBs owners mention: Recall issued for starter/solenoid for 2009-2011 Toyota models, but Venza was not included in that recall
Computer glitches causing loss of critical functions while driving
Vehicle display goes blank and all gauges fail while driving. Loss of power steering and brakes. Computer prevents starting the vehicle even when it is mechanically sound. No diagnostic codes present to help technicians identify the root cause.
When: While driving
Symptoms owners cite: Display goes blank; All gauges fail simultaneously; Loss of power steering; Loss of power brakes; Vehicle will not start after shutting down; Brake pedal not recognized by computer
VSC, ABS, and brake warning lights with unsafe braking behavior
Multiple warning lights illuminate simultaneously (VSC, ABS, brake system warnings). Cruise control malfunctions with erratic acceleration and poor responsiveness. Issue recurs multiple times. In wet conditions, vehicle skids when braking, creating safety hazard.
When: During and after driving
Symptoms owners cite: VSC (vehicle stability control) warning light; ABS warning light; Brake system warning light; Cruise control accelerates on its own without pedal input; Cruise control response is jumpy and delayed; Vehicle skids when braking in rain
Codes mentioned: P.515 (VSC/TRAC malfunction), P.513 (Brake system malfunction)
Recalls/TSBs owners mention: Dealership claimed first time they had seen the issue; customers report it has occurred since 2009 model year in online forums
Seat heater burning smell and fire risk
Driver's side seat heater produces strong burning electrical wire smell when activated. ECU related to seat heater starts to melt. Multiple owners report the same issue. Some units covered under recall 14V743000, others fall outside the recall scope or warranty period.
When: At approximately 80,000 miles and beyond. Issue occurs when seat heater is turned on, whether vehicle is stationary or driving
Symptoms owners cite: Strong burning electrical wire smell from seat; Smell occurs immediately when seat heater is activated; ECU related to seat heater melts; Fear of electrical fire from occupants
Repairs/costs cited: ECU removal and heating element disconnection (Toyota repair approach, not replacement). One owner reported out-of-pocket repair; others denied coverage under warranty
Recalls/TSBs owners mention: Recall 14V743000 issued November 19, 2014 for front seat assembly seat heater/cooler, but some affected VINs excluded; warranty does not cover repairs beyond 3 years
SRS airbag warning light intermittent malfunction
SRS airbag warning light illuminates randomly with no apparent cause, sometimes while driving and sometimes while parked. Airbag sensors replaced multiple times without resolving the issue. Cost owners thousands of dollars in repair attempts that do not hold.
When: Intermittently, unpredictable timing
Symptoms owners cite: SRS airbag warning light comes on randomly; No pattern to when it occurs; Multiple sensor replacements do not fix the issue
Repairs/costs cited: Multiple airbag sensor replacements at cost of thousands of dollars; repairs do not provide lasting fix
Ignition switch noise and vehicle stalling
Loud noise emitted from ignition switch while driving at highway speed. Separate incident: vehicle stalls completely with entire instrument cluster illuminated. Both events at relatively low mileage.
When: At 9,000 miles (stall/cluster) and 73,000 miles (ignition noise)
Symptoms owners cite: Loud noise from ignition switch; Vehicle stalls while driving; Entire instrument cluster illuminates; Spark plug electrical connector found loose
Repairs/costs cited: Spark plug electrical connector tightened
Rear liftgate sudden uncontrolled descent
Rear power liftgate, when opened via key fob, suddenly closes with force while owner is loading groceries. Liftgate strikes owner in the head with enough pressure to knock them to their knees, causing head contusion and concussive symptoms.
When: During operation of rear liftgate
Symptoms owners cite: Liftgate descends without warning after being opened; Excessive closing force
Unintended acceleration and parasitic drain on battery
Vehicle accelerates without driver input on pedal. Rear hatch operation causes repeated battery drain requiring jump starts. Noise present in rear and front of vehicle.
When: During operation and while parked (battery drain with rear hatch open/close)
Symptoms owners cite: Vehicle speeds up without stepping on accelerator pedal; Does not slow down as expected; Battery goes dead when rear hatch is opened and closed; Noise in rear and front of vehicle

What owners are reporting 3 most recent
While driving on the highway I noticed a "rubber burning" smell. I took the vehicle into the dealership the next day. I was told that the ECU related to my driver seat warmer had started to melt. The ECU was removed and the heating element for my driver seat was disconnected. Toyota will not cover replacement of this part stating that it is out of the 3 year warranty period. I pointed out that…
This is the third occurrence in a year. The vehicle will randomly turn on and attempt to start. There is no fuel going to the engine, so it does not ignite, but I have read reports if venzas doing this and catching fire. The other challenge is that when this happens, it also activates the engine immobilizer and will not recognize the keys. The first time, last january, we returned from a trip…
