What 473 owners told NHTSA about the 2021 Toyota Highlander

Four days after I took delivery of this used vehicle (April 25, 2026), multiple warning lights appeared at once: BRAKE, ABS, PARK, Check Engine, Blind Spot Monitor Unavailable, and RCTA OFF. An independent Toyota dealership diagnosed the vehicle April 27-28, 2026 (approx. 109,000 miles) and found (1) water leaking into the rear hybrid battery area through a sunroof drain "installed incorrectly," causing a Brake System Control Module low-voltage code, starting issues, a headlight only partially functioning on one side, possible air in the brake system, and a musty HVAC odor; and (2) blind spot monitor fault code C1AC2 (Slave Module Horizontal Axis Misalignment) - the blind spot and rear cross-traffic monitoring systems do not function reliably. At a second visit on May 4, 2026, recalibration was unsuccessful; per Toyota procedure the only remaining option is replacing the right-rear blind spot sensor. The technician wrote the cause is a mystery, "whether it be body damage related or electrical short." Toyota service records show the same C1AC2 code was documented during the selling dealer's own pre-sale inspection, and that in December 2024 another Toyota dealership pulled the rear bumper and found the RR blind spot sensor bracket bent, causing incorrect readings - a recurring safety defect that prior calibrations and repairs have not resolved. Separately, federal safety recall 23V865 (occupant classification sensors; the passenger airbag may not deploy as designed) was open and incomplete when I purchased the vehicle and remains incomplete, and Toyota service campaign 25TD01 (rear traction motor cable corrosion) is also outstanding. The defect has been reproduced and confirmed by two Toyota dealerships, reported to the selling dealer in writing, and reported to Toyota's customer-care center. The vehicle is available for inspection upon request. No crash, fire, or injury.

The contact owned a 2021 Toyota Highlander. The contact stated that while his wife was driving at an undisclosed low speed and in the process of merging into the highway, the vehicle was suddenly rear-ended in the rear quarter panel area, near the rear tire, causing the vehicle to face oncoming traffic. The driver-side and passenger-side air bags did not deploy. The message "Park Brake Malfunction" was displayed. The contact transported his wife to an urgent care clinic the evening of the incident for a medical check-up because the contact's wife was pregnant and was starting to feel pain. The contact's wife sustained neck injuries. A police report was filed. The vehicle was towed to a tow yard. The insurance company was notified of the incident and towed the vehicle to Copart to be inspected. The vehicle was totaled. The manufacturer was not made aware of the failure. The failure mileage was approximately 51,000.

The airbags did not deploy when I was involved in an accident on the freeway July 2025. During the collision, there was a message on the driver dashboard that read "SRS Airbag System Malfunction Visit Your Dealer". When I took my Highlander into the collision autobody shop, they notified me that my car had an open recall and that I needed to get in touch with manufacturer or schedule an appointment with a local Toyota dealership to see if they could remedy the recall as soon as possible. When I called Toyota, they confirmed that there was a recall on the Highlander's that opened in 2023 and that there was supposed to be a remedy in 2024, but unfortunately there is still no remedy available. They let me know that I would not be able to bring the vehicle in for service and that the collision center would not be able to remedy the situation on Toyota's behalf. This safety issue put myself and my family that includes multiple children that were in the vehicle at the time of the accident, in a very unsettling situation. We were afraid to drive the car any further than 5 miles or on the freeway, wondering if the airbags would deploy at any minute. There was little to no information provided whether the airbags were in fact supposed to deploy upon impact compared to if it was just a sensor mishap. There were no prior warnings, message, symptoms or mailers sent out notifying us that there were any recalls on the car.

The component that has failed is the passenger airbag system under Toyota Recall 23TA15 (Interim Notice 23TB15). The recall notice states that the passenger airbag may not deploy in the event of a crash. My vehicle is a 2021 Toyota Highlander (VIN: [XXX] ). This safety defect has been outstanding and unresolved for over 21 months with no available repair or remedy. The vehicle is available for inspection upon request. The safety of my family is directly at risk. I am a mother of three young children, and we frequently travel with passengers in the front seat. If the passenger airbag does not deploy during an accident, it could result in catastrophic injury or death to anyone sitting in that seat. This ongoing recall forces me to make a difficult choice between risking my family’s safety or not using the vehicle as intended. The problem has been acknowledged by Toyota and confirmed by their recall notice. I contacted Toyota and opened a case with their Brand Engagement Center, but they denied my request for assistance and informed me there is no current remedy. I was told my case has been taken to the highest level within Toyota and that the only option left is to pursue lemon law. The vehicle has been inspected and serviced at Toyota authorized facilities in the past, and Toyota has my warranty and repair history. However, since the recall remedy does not yet exist, no inspection has resolved the issue. There have been no warning lamps, dashboard messages, or other visible symptoms prior to or during this recall; the only notice is Toyota’s acknowledgment that the defect exists and has not been fixed. In summary, I have been forced to drive an unsafe vehicle with a known airbag defect for nearly two years. This delay in remedy is unacceptable and puts my family and the public at risk every day. I am requesting NHTSA’s assistance in holding Toyota accountable for this unresolved safety recall. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am reporting that the fix for NHTSA recall #23V-865, Toyota recall #23TA15 has not been done in a timely manner & I am concerned for the safety of my passengers. The recall info came out December 2023 & Toyota was supposed to have a fix 3rd quarter 2024. We are now in 2nd quarter 2025 & there is still no fix. This is unacceptable. Again, I am concerned for the safety of my passengers, one of which is my elderly mother-in-law who has difficulty getting in & out of the back seat.

Toyota continues to knowingly not remedy an airbag sensor issue. My vehicle has the light on indicating it is suffering from the same recall. I bought this car from them in 2024 and they sold it to me with the knowledge that there was a safety issue. I’ve tried to find a solution as this is a major safety issue. Toyota took my money in full for the car, yet can only offer me a loaner for 25 days. They said in CA, it most likely won’t get fixed until the end of 2026. I don’t have money. I have one car and I need a vehicle to transport to work and kids to school. This is not right and this is not safe. A remedy for people in CA that won’t be fixed for two more years that is an ACTUAL SAFETY issue , is not right. This is to document the safety complaint as the dealership continues to ignore the issue, and the 1-800 Toyota line continues to ignore it. All BBB complaints shows I’m not the only one. I can’t take a rental because they won’t pay me back, it’s not guaranteed, and I’m out another $40,000. They put people in impossible situations. The manager at the service center it’s your fault if you walk out of here without taking a loaner. You’re choosing to put your family at risk. And I said no, you’re offering me a loaner and you can’t guarantee a vehicle that will fit my family. I don’t know what to do.

This vehicles airbags have been under recall for over one year!! Toyota should’ve had a remedy for this issue by now. They also stated that they would have a fix for this by the third quarter of 2024. It is 2025! This issue needs fixed now!! We have young children that ride in this car every single day! This is completely unacceptable and needs reported and fixed now!

The recall on the passenger airbags for Toyota cars has not been resolved for a few years now. We owned a 2013 Rav4 for a few years and that airbag was never fixed. Now we own a 2021 Toyota Highlander with the same problem. What's Toyota going to do about it? My husband drives the car so I'm the passenger and I don't feel like dying. ?"???

If the important safety recall on 2021 highlander is that important, why is it taking years to fix , I feel toyota is dragging their feet and no one from the Nhtsa is doing anything about it, I think social media will be informed about your inaction of letting them slide for so long !

NHTSA ODI 11625567

My Toyota Dealer, Toyota Corporate Customer Service, Toyota Recall Web site, and NHTSA web site have no remedy, no scheduled remedy, and have sent no status reports since recall 23TA15 was issued 12/20/2023. The only data that I can find states an estimated fix by October 2024. Almost 1M vehicles are impacted by OCS defective part that may cause the passenger air bag to fail causing serious injury or death. Toyota an NHTSA should take immediate action to make sure that there is a sense of urgency (after almost a year), an action plan is in place, and owners are kept informed on a timely basis.
