2022 Toyota RAV4 Problems: 6 Known Issues

How to Fix

Check the complete VIN through Toyota's recall lookup or an authorized Toyota dealer. The current 23TA07 remedy replaces the DC-DC converter with an improved part free of charge. The earlier cold-temperature charging restriction was interim guidance and should not replace completion of the available remedy. If heat, smoke or a burning odor is detected, stop safely, switch the vehicle off, move occupants away and contact emergency services as conditions require. Do not diagnose an open recall from generic warning lights, a no-start or a discharged 12V battery alone.

Owner tips & cautions

• TipUse the complete VIN to check 23TA07 eligibility; 43,442 is the total RAV4 Prime/Lexus recall population, while Toyota lists approximately 41,500 covered RAV4 Prime vehicles.
• WarningThe improved-converter remedy is available; do not rely on the old temporary cold-weather charging restriction instead of completing the recall.

How to Fix

First clean the rear-bumper sensor areas and document the exact warning or indicator behavior. If a 2021-2022 RAV4 Prime matches the bulletin condition, a Toyota dealer or qualified technician should confirm it under T-SB-0027-22 and install both specified BSM covers, part numbers 88163-42020 and 88173-42020, while completing any required initialization or calibration. If the condition does not match, continue repair-manual diagnosis. The bulletin listed occurrence-only coverage under the original 36-month/36,000-mile basic warranty; confirm current coverage before authorizing work.

Owner tips & cautions

• TipPhotograph the warning or stuck mirror indicator and note weather, road contamination and any recent bumper contact before cleaning the sensor areas.
• WarningDo not apply the bulletin's cover repair to other RAV4 years or models without vehicle-specific diagnosis.

How to Fix

Check the complete VIN with an authorized Toyota dealer and have the connector inspected under CSP 22TE09. If Toyota's condition and inspection criteria are met, the dealer repairs or replaces the affected floor-under harness and replaces the rear traction-motor cable only when the inspection standard requires it. Program coverage is eight years from first use or 100,000 miles, whichever comes first, and applies only to dealer work under the program terms. Warning messages or a no-start require prompt diagnosis; do not touch or clean a high-voltage connector. Do not order a harness yourself; the floor harness is model-year- and plant-specific.

Owner tips & cautions

• TipBring the complete VIN plus any warning-message photo or scan report; CSP eligibility and the repair path depend on production data, symptoms, DTCs and Toyota's connector inspection.
• WarningThis is a high-voltage circuit. Do not touch, disconnect, probe or clean the underbody connector; use a qualified Toyota hybrid technician.

How to Fix

With the engine cool, verify coolant level and inspect the entire cooling system so another source is not attributed to the pump. Follow T-SB-0103-20 Rev1 and document the condition: dry residue alone is a temporary-leak condition and does not call for pump replacement; fresh wet residue or drips indicate an active leak. A qualified technician should also evaluate abnormal pump noise, pulley/bearing play and rotation under the applicable repair manual. Replace only the confirmed failed component, refill with the specified coolant and verify the repair; do not schedule pump or thermostat replacement from mileage alone.

Owner tips & cautions

• TipPhotograph the pump area before cleaning it and distinguish dry residue from fresh wet coolant or drips; Toyota requires clear active-leak documentation for warranty claims.
• WarningDo not replace the pump from dry residue, mileage or unrelated cam-timing DTCs alone; rule out other coolant sources and confirm the pump condition first.

How to Fix

If fuel odor is present, avoid ignition sources and arrange prompt diagnosis at an authorized Toyota dealer. Ask the dealer to verify VIN, production/engine applicability and the CSP's ten-year-from-date-of-first-use coverage, which has no mileage limit. T-SB-0008-23 requires confirmation that the odor is present in the engine bay and originates at the high-pressure pump; if verified under 23TE01, Toyota replaces the pump free of charge. A nonmatching odor continues through normal diagnosis, and the owner may owe initial diagnostic fees. Do not order a pump by a generic part number; Toyota controls the covered part by VIN/EPC.

Owner tips & cautions

• WarningTreat a persistent fuel odor as a prompt-inspection issue and avoid flames, sparks and smoking near the vehicle until the source is identified.
• TipBefore the appointment, note when the odor occurs, whether HVAC is in fresh-air mode and whether the vehicle was just refueled; do not refuel immediately before the visit if avoidable.

How to Fix

Have a Toyota dealer check it. The bulletin applies only when the oil looks milky or discolored: the technician checks the oil and pressure-tests the cooling system first, because an internal coolant leak can look the same and takes the vehicle outside the bulletin. If the cooling system holds pressure and an Oil Pressure Low warning or code P05202A/P052477 is present, the technician clears codes, warms the engine (maintenance mode on hybrids) and, if the warning returns, replaces the oil and filter and re-checks; if it still returns, the bulletin no longer applies and normal diagnosis continues. If the oil is milky but there is no warning or code, or the warning does not return, the bulletin calls for an oil and filter change and wiping milky residue from the underside of the oil filler cap. Use the oil grade on the under-hood label. Normal warranty rules apply; this is not a recall or a promise of free repair (the bulletin's warranty table reads "Not Applicable to Warranty").
