Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering visibility on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
TSB: Some 2020 ? 2022 model year Highlander and RAV4 vehicles, and 2022 model year Tundra vehicles equipped with a start/stop switch may exhibit water entry to the vehicle from the HVAC drain hose being disconnected from the air conditioning radiator assembly and/or a grease/oil odor emitting from the vents. This condition may be caused by paraffin wax leaking from the evaporator. Follow the repair procedure in this bulletin to address this condition.

The failure pattern owners describe
Owners of 2021 RAV4s describe four distinct visibility and glass failures. Rear-view mirror vibration is the most common complaint—external mirrors shake severely at highway speeds (50–70 mph), distorting the reflection and making it hard to judge other vehicles' positions when changing lanes. Toyota has TSB T-SB-0079-20 that addresses inadequate factory mounting studs and brackets, but repair is limited to vehicles under 36,000 miles or 3 years. Owners outside this window report being denied coverage despite Toyota's documented acknowledgment of the defect. Repair costs exceed $1,000, and one owner's dealership couldn't locate a repair kit.
Sunroof spontaneous shattering has occurred at various mileages (1,500 to 56,413 miles) while driving at highway speeds with no external impact. Glass breaks outward, creating shrapnel that has struck occupants and posed hazards to other vehicles. No warning precedes these failures.
Windshield defects appear in two forms: distortion visible upon delivery or early ownership that causes severe eye strain and blurred vision, and spontaneous cracking from the bottom edge with no external cause. One dealer acknowledged all RAV4s on its lot had defective windshields but refused replacement due to risk of receiving equally defective replacement glass.
One owner reported a front driver-side power window regulator failure at 32,804 miles, rendering the window inoperable.

Failure modes owners describe
Rear-view mirror vibration and distortion
Exterior rear-view mirrors vibrate at highway speeds (50–70 mph), producing distorted images that compromise blind-spot monitoring and safe lane changes. Owners report the vibration worsens over time and persists across normal driving conditions. The defect stems from inadequate factory mirror mounting studs and reinforcement brackets.
When: Begins shortly after purchase; worsens at 30+ mph, severe at 50–70 mph. One owner at 127,000 miles still reports active vibration.
Symptoms owners cite: Visible vibration of mirror glass at highway speeds; Shaky, distorted image of surrounding vehicles; Difficulty judging position and speed of adjacent vehicles; Mirror glass vibrates internally, making mirrors difficult to use safely
Repairs/costs cited: Toyota TSB T-SB-0079-20 calls for installation of longer mounting studs, reinforcement brackets, and bonding adhesive. One owner reports dealership unable to locate repair kit. Another owner reports repair cost exceeds $1,000.
Recalls/TSBs owners mention: Toyota acknowledges defect via TSB T-SB-0079-20 but limits warranty coverage to 3 years/36,000 miles. Owners outside this window are denied warranty coverage despite known manufacturing defect. No public recall issued; many owners discover the TSB only through online forums and social media.
Panoramic sunroof spontaneous shattering
Panoramic sunroof glass spontaneously shatters while vehicle is in motion on highways, with no external impact or collision. Glass breaks outward and creates dangerous shards that pose injury risk to occupants and potential hazard to surrounding traffic. Occurs without warning or prior symptoms.
When: Occurs at various mileages: 1,500 miles, 50,000 miles, 56,413 miles. One incident at approximately 5 weeks after purchase.
Symptoms owners cite: Loud bang or booming sound preceding shattering; Sudden wind noise entering cabin; Complete sunroof glass failure while driving at highway speeds (65–75 mph)
Repairs/costs cited: Owners paid out-of-pocket for replacement glass and repairs; dealer repair costs not specified in narratives.
Recalls/TSBs owners mention: Manufacturer denied warranty claims, citing insufficient evidence of factory defect or outstanding recall. Dealers deny involvement and claim no reoccurrence data. No recall issued.
Windshield spontaneous cracking and distortion
Windshields develop cracks radiating from bottom edge or exhibit visible waves and distortion in the glass without external impact. One new vehicle had visible distortion upon delivery; another cracked while parked. Distortion causes severe eye strain and blurred vision, rendering vehicle unsafe to drive.
When: Issues appear early: one new vehicle had distortion within 20 minutes of delivery; one cracked at 5 weeks old; one at 8,500 miles; one while parked at 64 degrees with no impact.
Symptoms owners cite: Visible distortion and waves in glass; Blurred vision through windshield; Eye fatigue and strain from prolonged focus; Spontaneous cracks radiating from bottom edge near wiper toward center; Cracks with no external cause (rocks, chips, impact)
Repairs/costs cited: Dealer confirmed distortion but refused repair, noting all RAV4s on lot had defective windshields with varying severity and risk of worse replacement.
Recalls/TSBs owners mention: Dealers acknowledge defect but do not honor warranty repairs. One dealer stated this was not the first complaint and expressed concern that replacement glass may be equally defective.
Front driver-side power window regulator failure
Power window regulator on front driver-side window failed, rendering the window inoperable. Window became stuck off-track and power button did not function.
When: Approximately 32,804 miles
Symptoms owners cite: Power button does not function properly; Window off track and inoperable
Repairs/costs cited: Dealership diagnosed window regulator failure requiring replacement; vehicle was not repaired per narrative.
Recalls/TSBs owners mention: Manufacturer was made aware of failure; no warranty resolution mentioned in narrative.
