On the 2019 Toyota Avalon, certain 2019 Avalon and Avalon Hybrid vehicles carry an airbag electronic control unit that can erroneously register a fault during the power-up self-check that runs every time the car is started. When the ECU latches that false fault, it disables deployment, so in a crash the front and/or side airbags and pretensioners may not fire. Because the fault is intermittent and self-generated, the SRS warning light is the only outward sign and it may not be present on every start. Toyota reported these vehicles as non-compliant with FMVSS 208 (Occupant Crash Protection) and FMVSS 214 (Side Impact Protection). A separate, later Toyota action covers a short circuit in the Occupant Classification System sensor that can keep the front passenger airbag from deploying - a different defect that owners often confuse with this one.

Common Symptoms

  • SRS / airbag warning light on, sometimes intermittently after a cold start
  • Airbag system disabled with no stored crash event
  • Passenger airbag OFF indicator behaving inconsistently

How to Fix

Have the dealer perform the recall: the remedy is a reflash of the airbag ECU software, free of charge, and it is a short appointment. Do not treat a lit SRS light on one of these cars as a bad clockspring or seat sensor until the recall status has been checked - a reflash costs nothing and rules the ECU out. If the SRS light persists after the software update, scan the SRS module for stored B-codes rather than clearing the light.

On the 2019-2020 Toyota Avalon, the in-tank low-pressure fuel pump supplied by Denso uses a resin impeller that was molded with too low a density. The impeller absorbs gasoline, swells and deforms, then cracks and contacts the pump housing, which stops the pump. On the XX50 Avalon this produces a rough-running engine, warning lights, and eventually a stall at speed with a no-restart condition. NHTSA campaign 20V-012 (Toyota campaign 20TA02) covered the 2019 Avalon and was later expanded to additional model years and models; the overall Denso pump action grew to cover roughly 696,000 Toyota and Lexus vehicles at first and millions across successive expansions. Owners report the failure comes on suddenly rather than after a long warning period.

Common Symptoms

  • Engine stalls while driving, sometimes at highway speed
  • Engine will not restart after a stall
  • Rough running, misfire, hesitation on acceleration
  • Check engine light and multiple instrument-panel warning messages
  • Long crank or hard start

How to Fix

Check the VIN on the NHTSA recall lookup - if the vehicle is covered, the dealer replaces the entire fuel pump assembly with a revised, higher-density impeller pump at no charge. If the vehicle is out of the campaign scope or the recall was already performed and the symptom returned, the fix is the same: replace the in-tank low-pressure fuel pump assembly with the current revised part number, not a rebuilt original. Do not simply clear the codes - a swelled impeller does not repair itself.

On the 2005-2022 Toyota Avalon, the front strut mount bearings on the Avalon wear out and develop a popping, creaking, or clunking noise when turning the steering wheel, particularly at low speeds and when turning while stationary (like parking maneuvers). The bearing allows the strut to rotate as the wheels turn — when it wears, metal-on-metal contact creates the noise. The noise is most noticeable in cold weather and first thing in the morning. The issue affects all generations of the Avalon but is most common after 60,000-80,000 miles.

Common Symptoms

  • Popping or clunking noise when turning steering wheel
  • Creaking sound during slow-speed turns
  • Noise from front of vehicle when parking
  • Steering feels rough or catches during turns
  • Noise worse in cold weather or first drive of the day

How to Fix

Replace the front strut mounts and bearings ($80-$150 per side for parts). The strut must be removed and disassembled using a spring compressor to access the mount bearing — this is a job for a shop unless you have spring compressor experience ($300-$500 labor for both sides). Most shops recommend replacing the struts at the same time if they have over 80,000 miles, since the labor overlaps. A complete strut assembly with pre-assembled mount and spring ($200-$350 per side) eliminates the need for a spring compressor and simplifies the repair. A wheel alignment ($100-$150) is required after strut work.

Owner tips & cautions

  • TipBuy complete strut assemblies (Monroe Quick-Strut or KYB Strut-Plus) with the mount, bearing, and spring pre-assembled. They bolt right in without a spring compressor and cost only slightly more than mount-only replacement. Much safer for DIY.

AIR BAGS:FRONTAL

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2020-2021 Toyota Avalon and 2020 Avalon Hybrid, RAV4, and RAV4 Hybrid vehicles. Breakaway pins within the steering column, designed to absorb energy and reduce injury during a crash, could have been damaged during production, possibly affecting the performance of the driver's air bag in the event of a crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "Occupant Crash Protection."
