The 2021 Venza is Toyota's RAV4-based hybrid crossover built on the TNGA-K platform with a 2.5L hybrid powertrain. Generally reliable as a new model, but we're seeing premature hybrid transmission issues and some fuel system quirks that are atypical for Toyota hybrids.
Hybrid Transmission Oil Cooler Failure
Occasional · high severity
Typical onset: 40,000-70,000 mi
Symptoms: Transmission overheating warning on dash, Reduced power mode or limp mode activation, Visible coolant or ATF leaks under vehicle near transmission bell housing, Milky or contaminated transmission fluid on dipstick check
Fix: Replace transmission oil cooler assembly and flush both cooling system and hybrid transaxle fluid. Requires dropping subframe for access. 6-8 labor hours at indie shops, may need Toyota dealer for hybrid system bleeding procedure.
Estimated cost: $1,800-3,200
Transmission Mount Premature Wear
Common · medium severity
Typical onset: 30,000-60,000 mi
Symptoms: Clunking or thudding when accelerating from stop, Vibration at idle that worsens with A/C on, Excessive drivetrain movement visible when rocking vehicle in park, Transmission shifting feels harsher than normal
Fix: Replace front and/or rear transmission mounts. The hybrid transaxle is heavier than conventional automatics and Toyota may have underspecced the mounts initially. 2-3 hours labor, straightforward job.
Estimated cost: $400-750
Fuel Filter Housing Crack / Fuel System Pressure Loss
Occasional · high severity
Typical onset: 50,000-90,000 mi
Symptoms: Extended cranking before engine starts, especially when hot, Random stalling at idle or low speeds, Check engine light with P0087 (fuel rail pressure too low) codes, Strong fuel smell near fuel tank or under rear seat area, Visible fuel weeping at filter housing seams
Fix: Replace fuel filter assembly and associated O-rings/seals. Some units have cracked housings from thermal cycling. 2-3 hours labor, requires fuel system depressurization and may need fuel tank drop depending on access.
Estimated cost: $600-1,100
Electronic Stability Control Module Software Glitch
Rare · medium severity
Symptoms: Traction control light flashing randomly during normal driving, VSC system warning on dash with no actual traction events, Intermittent loss of stability control intervention, ABS warning light accompanying VSC warnings
Fix: Covered under TSB and recall for ESC module software update. Dealer-only reflash, 1 hour labor typically covered under warranty or recall. No parts replacement needed, just software correction.
Estimated cost: $0-150
Hybrid Battery Cooling Fan Noise / Failure
Occasional · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Loud whirring or grinding noise from rear cargo area during acceleration, Reduced hybrid system performance or frequent ICE running, Hybrid system warning with P0A93 or P3191 codes, Visible dust/debris accumulation on hybrid battery intake vents under rear seat
Fix: Replace hybrid battery cooling fan assembly and clean battery pack intake filters. Fan bearings fail prematurely from dust ingestion. 3-4 hours labor includes removing rear seat and battery service panels. DIY-friendly if comfortable with 12V disconnect procedures.
Estimated cost: $800-1,400
Owner tips
Check transmission fluid level and condition every 30,000 miles despite Toyota's 'lifetime fill' claim — early cooler failures contaminate fluid
Inspect transmission mounts during every oil change; catching wear early prevents secondary damage to CV axles and subframe bushings
Replace cabin air filter every 15,000 miles to protect hybrid battery cooling system from dust ingestion
Keep ESC module software updated at dealer during routine maintenance — the 2021 MY had several revisions
A solid hybrid crossover with typical Toyota reliability, but watch for early transmission issues and budget for mount replacements before 60K — otherwise a safe used buy with proper maintenance records.

Fitment notes: AGM battery required for hybrid system; lower CCA specification due to hybrid starter assistance

Toyota Engineering & Manufacturing (Toyota) is recalling certain 2022 Lexus LX 600, Lexus NX 350h, Lexus NX 450h+, Toytoa RAV4 Hybrid, 2021-2022 Lexus LS 500h, Toyota Mirai, RAV4 PRIME, Sienna, Venza, and 2020-2022 Toyota Highlander Hybrid vehicles. The Skid Control ECU software may not turn on the Vehicle Stability Control (VSC) system when the vehicle is restarted after the driver has disabled the VSC system. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 126, "Electronic Stability Control Systems."
Consequence: Driving with a deactivated stability control system increases the risk of a crash.
Remedy: Dealers will update the Skid Control ECU software, free of charge. Owner notification letters were mailed May 27, 2022. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this recall is 22TA03. Lexus' number for this recall is 22LA01.
