When driving I had to brake hard to avoid a collision. My daughter was riding in the front passenger seat. Both my daughter and myself were buckled in our seat belts. When I had to brake, her seat moved all the way to the front position and she was thrown forward towards the front windshield. There is an active recall for my car where the recliner assemblies in the second-row seats may not fully lock after seat back adjustment. This seems to be the exact same issue but we experienced this with the front passenger seat. I reported the issue to Toyota but my vehicle has not been inspected yet. I am having the rear recall fix completed in late November. The issue put my daughters safety at risk and was very alarming for both of us. There were no warning messages or symptoms of a problem with the seat.

My 2021 Toyota Highlander XLE began making a high-pitched whining noise when accelerating. When researching this noise, associated with the make, model, and year of my vehicle, it became apparent that the noise is associated with a manufacturer's defect in the [XXX]‑speed transmission (Toyota [XXX]). The cited notification states that the correction for this defect is a transmission replacement that is only covered by the 60,000 mile/5 Year warranty. There are three class-action lawsuits associated with this issue, and I wanted to document my incident in the event that my service appointment with [XXX] Toyota in [XXX], on 11/23/2026 indicates that my transmission is affected by the defect so many have experienced.

I recently purchased a 2021 Toyota Highlander Platinum. Within a few weeks from purchase, the transmission started making a whining noise. Upon further research, it was discovered that Toyota has been installing the UA80=F transmission in their vehicles, knowing full well that there are serious issues with this particular transmission. But yet they continued using this transmission. Someone needs to address this issue and hold their feet to the fire.

On November 19, 2025, the 12.3-inch infotainment display in my 2021 Toyota Highlander Limited went black and never recovered. That screen is the only display for the rear-view backup camera. With it dead, there is no backup camera image when reversing. The failure started as an intermittent blank screen with the reverse camera still working, then progressed to a fully dead screen including the backup camera display. A replacement display unit did not fix it. Toyota has acknowledged this defect in Technical Service Bulletin T-SB-0055-22, which identifies the integration control sub-assembly (part 840C2-48010) as the cause, but has not issued a recall. Toyota service repeatedly diagnosed the problem as a failed head unit. I replaced the head unit at my own expense and the screen still did not work. When I returned to the dealer, they refused to perform further diagnostics, stating the diagnostic cost would be as much as the head unit replacement.

The contact owns a 2021 Toyota Highlander. The contact stated that while driving at an undisclosed speed, there was a loud high-pitched whining sound coming from the vehicle. The contact stated that the vehicle hesitated while accelerating and the transmission was shifting rough. The contact stated that the vehicle had experienced an internal transmission failure. The manufacturer was notified of the failure. A local dealer was contacted and associated the failure with Toyota Technical Service Bulletin: 0008-21. The contact stated that a diagnostic test was scheduled. The failure mileage was 70,100.

Noticed a whine noise slowly progressing over a couple of weeks. Researched the sound and took it for diagnostic eval. with Holman Toyota in Mt. Laurel, NJ on 10/3/2026. As suspected, the transmission is failing. Mechanic documented via video the fluid sample containing suspended metallic particles with discoloration and burnt odor. They also verified the whining sound coming from the transmission. This is a known failure for the 2021 highlander with a TSB bulletin. Although they have yet to place a recall. There were no warning messages. The complete failure of a transmission while driving could cause sudden immobilization and most certainly result in an a motor vehicle accident. The vehicle has under 54,000 miles and is about 10 weeks outside the warranty.

When traveling at slower speeds and applying the brakes on a slight decline, my 2021 Toyota Highlander HYBRID lurches forward with alarming force. On probably 5 separate occasions, this has nearly resulted in me lurching into traffic running perpendicular to me. I have come within 2-3 feet of lunging into oncoming traffic and I am probably the poster child for defensive driving. I had to push the brake petal forcefully to stop. I have not allowed my daughter to drive my car because of this. I first noticed this maybe 2-3 years ago? That's a guess. Why have i waited? b/c i'm a fool and poor at executive function. I looked it up, and apparently Toyota is aware of this problem (T-SB-0059-23) but apparently has NOT ISSUED A SAFETY RECALL. This is truly shocking to me, considering the recalls i've seen so far with this vehicle have been for things that do not appear as alarming or potentially dangerous as this. According to Toyota, they will only cover this defect up to 36K miles or 36 months (whichever 1st). I called 2 of my local dealerships and neither "service mgr" knew anything about it. Unacceptable. One of them, AFTER they said this, refused to even look up the TSB#, stating 'that's not the way we do it. You have to make an appt.' Absolutely ridiculous. Toyota should be forced to ISSUE A SAFETY RECALL. I've read it's a software fix. CHEAP and EASY for a multi-national corp. Perhaps NHTSA was unaware of the seriousness of this problem before and I know that happens, but I'm here to tell you IT IS NOT SAFE. And i am famous for annoying people (especially my kids) for reminding them how many collisions could be avoided if EVERYONE JUST DROVE DEFENSIVELY! I have literally annoyed people by repeating it. PLEASE issue a safety recall and make them pay for it. I don't have unlimited $ to pay for such things in this economy. Thank you. - A concerned driver.

65K miles on the vehicle and have started to get a whining noise from the transmission during acceleration. UA80F transmission installed with multiple class action lawsuits against Toyota for this issue as it leads to catastrophic failure with high replacement cost. Stopped driving the vehicle and looking into transmission replacement options. Toyota needs to be held liable for mechanical defects.

We bought a 2021 Toyota Tacoma Platinum in November 2020. In February 2021, Toyota issued a Technical Service Bulletin T-SB-0008-21. The bulletin say transmissions may exhibit a whine or grind noise from the transmission. This condition may be caused by an issue with the front carrier assembly pinion shafts. This bulletin says repair is covered under the Toyota Powertrain Warranty. This warranty is in effect for 60 months or 60,000 miles, whichever occurs first, from the vehicle’s in-service date. Our transmission began making this noise around 75k miles, outside the warrant. Toyota knew about this problem over 5 years ago and did not take action to recall it. Now this repair is going to cost between $9,000 to $12,000 out of pocket. I cannot afford this repair. I have uploaded the bulletin from Toyota.

My 2021 Toyota Highlander is experiencing the exact bumper/under-cover detachment detailed in NHTSA Recall 23V720. In August 2025, an authorized dealer performed the interim 23TA12 clip remedy. That remedy has completely failed. The lower bumper and engine splash shields are unzipping and actively dragging on the ground, creating a severe road hazard. Fred Haas Toyota World on I-45N and Toyota Brand Engagement are both refusing to inspect this failed safety remedy unless I pay an out-of-pocket diagnostic fee. This is a direct violation of the National Traffic and Motor Vehicle Safety Act, which mandates all recall diagnostics and remedies be free.

I own a 2021 Toyota Highlander Platinum AWD equipped with the 3\.5L V6 and approximately 77,000 miles\. The vehicle developed a humming/whining, airplane\-like noise from the front drivetrain while accelerating\. The noise increases with vehicle speed and stops when the accelerator is released\. There is no vibration, and the vehicle makes the same noise while traveling straight\. I took the vehicle to an authorized Toyota dealer, Kerry Toyota, and the dealer diagnosed the transmission as the source of the noise and recommended replacement of the transmission\. The quoted replacement cost is approximately $7,600 plus tax\. Toyota previously issued Technical Service Bulletin T\-SB\-0008\-21 concerning a whine or grind from certain 2021 Highlander UA80 transmissions and identifying the front carrier assembly pinion shafts as a potential cause\. My vehicle is approximately 17,000 miles beyond Toyota’s 60,000\-mile powertrain warranty\. I contacted Toyota requesting goodwill assistance with the transmission replacement, and Toyota declined assistance\. I believe there may be many similar cases involving 2021 Toyota Highlanders equipped with the UA80 transmission, including vehicles experiencing comparable whining or grinding noises and premature transmission\-related failures\. I am reporting this because an internal transmission problem that develops shortly beyond the powertrain warranty may worsen and could potentially result in loss of vehicle propulsion\. I believe NHTSA should review this issue along with similar complaints involving 2021 Toyota Highlanders equipped with the UA80 transmission\.

Parked the car for three days after the 3 days when starting the car the beep notification was still there on dash board still same notification. Then my neighbor came looked at it and said the all Toyota have same issue with the AC. He advised me not to turn the AC on just use fan. He said that when AC is on part of the car where the air blow is freezing. Now it is concerning when winter comes to turn on the heater.

Toyota refuses to issue a recall for a well known issue with the UA80 transmission that fails around 5 years on many Highlanders. I follow [XXX] and there are countless posts about this issue. Mine failed at one month before my warranty was up and replacement was covered but it was replaced with the same transmission which I assume will also fail after 5 years or another 50,000 miles. There is a service bulletin for repair from Toyota so they're half admitting the issue but there needs to be a recall and a revision to the UA80 transmission to make them safer.

- 11007455Some 2005 2024 Toyota vehicles that have undergone water intrusion may exhibit a condition in which a musty odor is present. Follow the procedures in this bulletin to remediate the odor and address this condition. The purpose of this Service Bulletin is to provide general guidelines and procedures for odor remediation. This Service Bulletin provides a guide on how to prepare and treat the interior of the vehicle for odor remediation. Refer to the applicable model and model year Repair Manual and the EPA (Environmental Protection Agency) website for the most up-to-date safety and precautionary guidelines. This Service Bulletin is to provide a general overview and direction for the odor remediation process.
- 11007445The condition known as acid rain is caused by airborne chemicals or particles in the atmosphere, which mix with rainwater, nighttime dew, or high humidity to form acidic compounds. If these contaminants settle and remain on a painted vehicle surface, especially the horizonal areas of the hood, roof, and decklid, significant damage can occur. This damage is the result of actual etching of the paint and appears as pitting or water spots. As acid rain droplets on the vehicle surface evaporate, the concentration strength of the acid increases, causing deeper and more rapid damage. This evaporation and corrosive action also occur more rapidly on dark colored cars as direct sun heat increases. It is the dealers responsibility to protect and maintain the quality of the vehicles paint finish after receipt at the dealership prior to the first sale. In areas known for high frequency and/or concentration of acid rain (see Figure 1), frequent vehicle washing during high heat or humidity periods will minimize the potential for paint damage caused by acid rain. It is further recommended that either reverse osmosis or deionized water be used to prevent water spotting.
- 11007444To prevent brake rotor rust from forming during transportation and storage, wheel film will be used instead of a cardboard type of anti-rust cover. The purpose of the wheel film is to shield the disc brake rotor from weather elements and initial rust before the vehicle is delivered to the customer. Consequently, the film should remain on the wheel for as long as possible.
- 11007443Acid rain results from rainwater or other airborne moisture that become acidic due to industrial chemical impurities in the atmosphere. If these acidic compounds settle on an exposed vehicle, especially the horizontal areas such as the hood, roof, and decklid, significant damage to the painted surfaces can occur. Acid rain damage can typically be identified on vehicles by the presence of stains on the paint surface that resemble hard water spots. Unlike water spots however, acid rain damage cannot be removed by regular washing procedures. Also, because acid rain can etch and soften the paint, normal buffing or polishing repair procedures should not be attempted. This can cause further damage and result in visible depressions in the paint surface. The following are the three major categories of acid rain damage: Minor damage: requires only buffing to repair. Moderate damage: usually requires neutralizing, color sanding, and buffing. Severe damage: extending beyond 1/2 mil of clearcoat on a pearl, metallic, or solid color, requires neutralization, sanding, and repainting. In cases where acid rain damage is minor, neutralization and buffing with a liquid-type paint finessing product may provide an adequate repair. Only specially formulated products outlined in this bulletin should be used for that purpose. Unfortunately, other than minor damage, there is no simple method of determining the actual extent (depth) of acid penetration other than color sanding a representative affected area until there is no visible etching or depressions, followed by measuring the amount of paint removed with either a magnetic or digital-type film thickness gauge. The procedures in this bulletin are intended for use by qualified body/paint technicians and should not be attempted by inexperienced personnel. It is the dealers responsibility to protect and maintain the quality of the vehicles paint finish after receipt at the dealership prior to the first sale. Perform frequent vehicle washing, as often as daily, during high heat and humidity periods to minimize the potential for paint damage due to acid rain exposure. This is especially important in geographical areas known for high frequency and concentration of acid rain and industrial fallout.

- 11005153Toyota vehicles are currently protected with RapgardTM protective film designed to protect the horizontal painted surfaces. This material protects from acid rain, environmental fallout, and rail contamination.
- 11005149Vehicles may occasionally be subjected to contamination by airborne iron particles shed from railroad tracks, train wheels, exposure to heavy machinery facilities, grinding, welding, etc. This type of contamination can be identified by the presence of small, red or brown particles on the paint surface.

- 11003647To prevent brake rotor rust from forming during transportation and storage, wheel film will be used instead of a cardboard type of anti-rust cover. The purpose of the wheel film is to shield the disc brake rotor from weather elements and initial rust before the vehicle is delivered to the customer. Consequently, the film should remain on the wheel for as long as possible. SUPERSESSION NOTICE The information contained in this bulletin supersedes Service Bulletin No. PD017-04. The entire bulletin has been updated.
- 11003644Acid rain results from rainwater or other airborne moisture that become acidic due to industrial chemical impurities in the atmosphere. If these acidic compounds settle on an exposed vehicle, especially the horizontal areas such as the hood, roof, and decklid, significant damage to the painted surfaces can occur. Acid rain damage can typically be identified on vehicles by the presence of stains on the paint surface that resemble hard water spots. Unlike water spots however, acid rain damage cannot be removed by regular washing procedures. Also, because acid rain can etch and soften the paint, normal buffing or polishing repair procedures should not be attempted. This can cause further damage and result in visible depressions in the paint surface. The following are the three major categories of acid rain damage: Minor damage: requires only buffing to repair. Moderate damage: usually requires neutralizing, color sanding, and buffing. Severe damage: extending beyond 1/2 mil of clearcoat on a pearl, metallic, or solid color, requires neutralization, sanding, and repainting. In cases where acid rain damage is minor, neutralization and buffing with a liquid-type paint finessing product may provide an adequate repair. Only specially formulated products outlined in this bulletin should be used for that purpose. Unfortunately, other than minor damage, there is no simple method of determining the actual extent (depth) of acid penetration other than color sanding a representative affected area until there is no visible etching or depressions, followed by measuring the amount of paint removed with either a magnetic or digital-type film thickness gauge. The procedures in this bulletin are intended for use by qualified body/paint technicians and should not be attempted by inexperienced personnel. While the quality and durability of paint on Toyota vehicles is continuously being improved, it remains the dealers responsibility to protect and maintain the quality of the vehicles paint finish after receipt at the dealership prior to the first sale. To read, While the quality and durability of paint on Toyota vehicles is continuously being improved, it remains the dealers responsibility to protect and maintain the quality of the vehicles paint finish after receipt at the dealership prior to first sale. Perform frequent vehicle washing, as often as daily, during high heat and humidity periods to minimize the potential for paint damage due to acid rain exposure. This is especially important in geographical areas known for high frequency and concentration of acid rain and industrial fallout.

- 10252259TSB: Some 2018 ? 2022 model year Toyota vehicles equipped with a Premium Audio with Dynamic Navigation System require a Special Service Tool (SST) USB flash drive to update the map, points of interest, and system software. The SST is used with applicable vehicles to deliver the update, however, the process for generating license keys differs from previous generations. Before attempting to perform a map update, the expiration date of the dynamic subscription (stored in the head unit), must be checked. If the expiration date has not passed, a license key may be generated without the purchase of an Activation Card Number (ACN). Updating the map without the use of an ACN is considered an Embedded Navigation Update (refer to pg. 10) and performing this update does not extend the subscription to dynamic map services. If the subscription period has expired, or is expiring within the next 90 days, it should be recommended to the customer to purchase an ACN. Utilizing an ACN, will initiate the Dynamic Navigation Update (refer to pg. 4). This Dynamic Navigation Update will perform the embedded navigation update and provide dynamic map services for a period of two years from the date that the Dynamic Navigation Update is performed. ACNs are provided in a pamphlet available through the normal parts ordering system. Follow the process in this bulletin to perform the update.
