To whom this may concern, I have had many problems with the Toyota Rav-4. I had so many problems with my 2017 Rav 4, that I under pressure upgraded to the 2021 LE version. I have had many problems with the breaks. I have brought it in (3) times to be serviced since I purchased it in March of 2021. The breaks are still squeaking. I have also had problems with the electrical system. The dash panel…

What stands out
Owners have filed 37 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA electrical complaint has been filed on this vehicle in over 4 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2021 RAV4 shows a cluster of serious electrical failures affecting braking, engine control, and safety systems—sudden unintended acceleration with brake failure, dash electrical cascades, corrosion in hybrid wiring, and fires from unknown electrical sources. Owners report Toyota dealerships either cannot diagnose these issues or dismiss warnings as normal, with some problems appearing after warranty expires.
Owners describe a sprawling set of electrical and control system problems in 2021 RAV4s. The most dangerous are two incidents of sudden unintended acceleration where brake pedals failed entirely—one sent a vehicle into oncoming traffic, another into a pole. Both times Toyota's post-incident inspections found nothing wrong, despite witnesses and dashboard warnings.
Electrical cascade failures are widespread. Owners report all dashboard warning lights illuminating at once: battery malfunction, charging system failure, steering power loss, brake failure warnings, and hybrid system faults. Batteries drain dead in 3–7 days of sitting. Dealership battery replacement doesn't fix the underlying electrical problem, and owners are charged $500+ in diagnostic fees once warranty expires.
Multiple fires started in parked or recently-driven RAV4s, originating from the undercarriage or engine compartment with no prior warning lights. One fire occurred in a vehicle that had recent front-end repairs.
Door locks fail—power lock actuators stop working, forcing manual operation and defeating the auto-lock feature. One passenger door swung open during a turn. Hybrid-specific issues include corrosion in high-voltage harnesses and rear traction motor cables that disable cruise control, tire pressure monitoring, and collision avoidance. Repairs cost $2000–$7000 with parts on backorder for months.
Engine stalling at traffic lights and water pooling inside doors from weather-strip defects round out the pattern. Owners consistently report Toyota dealerships either cannot replicate issues or declare malfunctions normal operation.

Failure modes owners describe
Sudden unintended acceleration with brake failure
Vehicle accelerates without driver input; brake pedal does not engage or brakes fail entirely. In one case, auto-braking system and parking brake failed to stop the vehicle, forcing it into oncoming traffic. In another, brake malfunction warning appeared on dash during hold-button use.
When: 10/6/2021 and 12/13/2021 for first complainant; 7/26/2023 for second
Symptoms owners cite: Sudden rapid acceleration; Brake pedal unresponsive or depressed with no effect; Brake malfunction warning message on dash; Auto-braking system failed to deploy; Vehicle unable to stop even when placed in park
Codes mentioned: BRAKE MALFUNCTION, CHECK ENGINE (Electronic Control Module malfunction)
Repairs/costs cited: Toyota dealership inspections found no defects both times; one owner noted water drainage pillars were cited as potential short-circuit source after collision
Recalls/TSBs owners mention: Toyota inspection reports stated no issues found; owner was told brakes were never engaged despite witness account and dashboard warning
Electrical fire in vehicle
Vehicle fire initiated from electrical or engine component, often from undercarriage or engine compartment area. Multiple cases report fire with no prior warning lights. Fires spread rapidly and caused total vehicle loss or near-loss in adjacent vehicles.
When: During normal highway driving; one case during 30-minute park; another after recent front-end repairs
Symptoms owners cite: Smoke from front bumper or engine compartment; Burning rubber smell; Flames beneath front left bumper area (fog light region) or from engine compartment; Rapid fire spread; No warning lights or messages prior to fire in most cases
Repairs/costs cited: Vehicles completely destroyed or salvaged; one case had prior front-end repairs (bumper, fog light); insurance claims filed
Recalls/TSBs owners mention: Toyota unable to determine cause in one case; vehicle too damaged for evaluation in another
Door lock actuator failure (power locks inoperable)
Front passenger and/or rear passenger door lock actuators fail to lock or unlock using key fob or interior power lock buttons. Doors must be locked manually. Creates security vulnerability and defeats automatic locking while driving. In one case, passenger door flung open while vehicle was turning at low speed.
When: Progressive failure; started with one door, spread to second door in follow-up complaint
Symptoms owners cite: Door will not lock or unlock via key fob; Door will not lock or unlock via interior power lock button; Manual unlocking required from driver side; Door flung open while vehicle turning at ~20 mph with no prior warnings; Auto-lock feature during motion fails; Warning beep when attempting to lock vehicle
Repairs/costs cited: One owner charged $90 for lock diagnostic with no defect found; issue resolved temporarily then recurred
Recalls/TSBs owners mention: No acknowledgment of defect; dealer diagnostic charged to customer despite safety issue
Electrical system cascade failure (dashboard lights, battery drain, charging malfunction)
Multiple electrical components fail simultaneously or in cascade: dashboard lights all illuminate at once, battery drains completely during short inactivity periods, charging system malfunctions detected, battery replacement does not resolve secondary electrical failures.
When: Around 30k-38k miles; one case after only 3 days of non-use; one case at 53k miles
Symptoms owners cite: All dashboard lights illuminate simultaneously (tire pressure, traction control, check engine, ABS, brake, battery light, etc.); Charging system malfunction warning; Battery completely dead after 2-7 days of non-use; Parking brake malfunction warning; Pre-collision malfunction warning; Brake power low warning; Secondary collision brake system malfunction; Antilock brake system malfunction; Voltage abnormality warning; Steering power low warning; Engine stopped message; Power locks inoperable when car is off; Key fob does not unlock/lock vehicle; Display screen does not turn on; USB ports not drawing power; Headlights and interior lights do not work; Emergency brakes engage on their own

Engine stall while driving (auto stop-start malfunction)
Engine shuts off unexpectedly during driving, at stop lights, or at stop signs. Vehicle may restart automatically, or require multiple restart attempts. In one case, vehicle stalled in middle of road multiple times over 2-mile distance. Start-stop system displays flickering dashboard lights when restarting.

Symptoms owners cite: Engine shuts off at stop lights or stop signs; Engine shuts off in middle of road while driving; Multiple restart attempts required; Climate control display flickers during restart; Headlights dim or flicker when engine restarts; Vehicle stalls after restart while stopped
Repairs/costs cited: Toyota technical specialist could not determine cause and declared it normal behavior; many owners disable auto stop-start system via switch
Recalls/TSBs owners mention: Toyota declared flickering and stalling normal; heavy 605A battery installed to support frequent restarts
Hybrid system malfunction and corrosion (high-voltage harness)
Hybrid system shows malfunction warnings; root cause is corrosion in high-voltage floor harness or rear traction motor cable connection. Corrosion causes multiple sensor failures including tire pressure monitor, adaptive cruise, collision avoidance systems. Repair requires harness replacement; parts often on backorder.

What owners are reporting 2 most recent
Since I bought my brand-new car 1. the engine has stopped 5 times. 2. My windshield cracked. 3. There is low tire air pressure indicator that appears once in a while. A new battery was replaced, and it now cannot start. The message on the screen indicates: "IGNITION ON, Voltage abnormality steering power Low. Visit your Dealer." I took it the Dealer and now they are not able to find out what…
