Around Halloween 2025 my Toyota’s Transmission started slipping. I called a few places and no one except Toyota would address the issue except a local shop in [XXX] , Ridge Auto Repair who after checking out the vehicle said they can’t repair it because the parts are not available November 6th, 2025, The Shop LAG LLC was recommended to me by a family member, and they came to check out the Toyota, and they were convinced it was the Torque Converter and wanted $1300 to fix it. I paid them and after a few weeks they claimed it was the Transmission and wanted more money which they were paid. Weeks went by and no updates from them and they weren’t responding to my messages. When they finally responded they started saying the starter was bad, the differential, the fly wheel, etc, Again, we paid them more money, and again weeks went by without any updates. We paid a total of $9000.00 Their last attempt to fix the vehicle also failed and I’m left with a vehicle with no transmission, the entire front end taken apart and scattered all over my property and this was their last response. “Oh lord. So the original place we got the transmission from denied the warranty, but at the time it wasnt a problem we have insurance. So we summited a claim and thats why it was going to be shipped from another place. Well they kept telling me that it was coming this day then that day. I got a letter denying the claim Instead. I have tried to fight it, but they ended up dropping us after that. We are willing to install one in for free if your able to get your hands on one, because this whole ordeal has been a nightmare, but we got denied due to mileage with the claim. There was a difference in our timestamped pictures and the adress of where it went once it left. So they said it was driven on with a problem, because it was moved to there with a problem thats what they are denying my claims to fight it. I didn't want to say anything until it was final and we kne INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMA
My car all of a sudden has this sudden humming/high pitch sound. I had mechanic checked and he said coming from the transmission. I checked the Toyota forum and there's a widespread issues with their transmission. The issue started with the year 2017, These vehicles are equipped with the UA80F (AWD) and UA80E (FWD) 8-speed automatic transmissions. My 2019 is equipped with the UA80E. Toyota already recognized that they have problems with the transmission but only issued a recall for vehicles 2017-2018. They need to include Toyota highlander 2019.
This vehicle safety complaint is regarding my 2019 Toyota Highlander XLE, VIN [XXX] . A Toyota-authorized dealership, Sansone Toyota in Avenel, New Jersey, documented that the front driver axle is prone to freezing in the differential. This is a serious safety concern because if the axle seizes while the vehicle is in motion, it could cause sudden loss of control. This vehicle is used regularly as our family vehicle, including to transport our family of 6 with our young children. I am extremely concerned about continued operation of the vehicle while this documented condition remains unresolved. In addition to this safety-related axle issue, this vehicle has a broader history of serious mechanical problems. On May 13, 2022, after a recent service visit at DCH Brunswick Toyota, I reported that when I pressed the gas the vehicle was making an unusual noise like an old car, that the car delayed to speed when I pressed the gas, that I had to press the gas all the way in order for the car to move faster, and that it was not like this prior to service. At approximately 25,000 miles, I also asked that the brakes be checked because when we drove the vehicle and used the brakes, the car made a startling sound. In 2023, I also reported hard/heavy steering and jerking while driving. I reported transmission-related abnormal noises and drivability concerns while the vehicle was still within Toyota’s powertrain warranty period, but the condition was not properly diagnosed at that time. The transmission has since been confirmed by authorized Toyota dealerships to require full replacement. The vehicle also has a documented engine oil leak, leaking shock absorber, and prior recall history involving a stalling condition. I've filed this complaint with the federal safety agency due to the axle-related safety risk. Toyota is now on written notice of that condition. Mileage: approximately 101,000 Documenting safety issue: Sansone Toyota, Avenel, NJ Please review this potential safety defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION
Hi. I have a Toyota 2019 Highlander EXL. My problems is the transmission started to have the small whining noise every time I accelerates and I it's happened over 18 months ago and I didn't know that is the issues until I brought it to the Toyota Dealer for 75k maintenance. The Dealer has told me that the noise was abnormal and it's from the transmission and it's will cost me $13 K to replace with a new one. I believe in Toyota quality but now I will have to really think about it again for the next purchase ?. I don't understand why Toyota has known this issues because of many reported but never intend to fixed it. I'm not so happy with this . Please ask ToyoTa Corp to answer and do take the responsibility before someone is getting hurds Thanks Tom le
Traveling at approximately 60-65 mph on interstate 95 in Wakefield the vehicle suddenly downshifted causing a rapid deceleration to around 40 mph. It would not upshift requiring us to pull into the breakdown lane.
A wining started on my 2019 Toyota highlander. I took to mechanic and they confirmed it was transmission. There was no warning.
Loud whining noises from transmission, repeated unpredictable shifts making pulling out/merging unsafe
I own a 2019 Highlander at just barely over 55,000 miles. I began hearing a humming noise while accelerating and brought it into Toyota. They told me that bearings are worn in the transmission and I need a new transmission replacement, which will cost $11,569.21. I am shocked Toyota has not issued a recall and corrected this well-known issue. I am disappointed in Toyota, being a loyal customer over the years, if they can't guarantee quality or assist in the issue they know about, I will not trust Toyota again.
I am writing to you as a deeply loyal Toyota customer who is facing a distressing and financially significant situation with my 2019 Toyota Highlander. Our family has been committed Toyota owners for several decades. Over the years, we have owned a Toyota Corolla, Camry, and multiple Highlanders — and we currently drive two Toyota vehicles. We have consistently chosen Toyota over other brands because of the trust we place in your engineering, reliability, and the value Toyota stands behind. We even replaced all of our Honda vehicles with Toyotas because of that trust. We purchased our 2019 Toyota Highlander during the COVID-19 pandemic, paying above market value because we believed in the Toyota brand and its long-standing reputation for durability. We have never regretted that decision — until now. At approximately 95,000 miles, our Highlander began exhibiting a high-pitched humming noise and gear slippage. We brought the vehicle to our Toyota dealership, who diagnosed the issue as a complete transmission failure. The repair estimate provided was $17,000. We were also informed that this repair would not be covered under any existing warranty. We are not only shocked by the severity and cost of this failure on a well-maintained, 7-year-old vehicle — we are also deeply concerned by what we discovered in our research. There appear to be hundreds of complaints from other Toyota Highlander owners reporting the exact same transmission issue, across the same model years, suggesting this may be a widespread and systemic defect rather than an isolated incident. Given this context, we respectfully ask Toyota to consider the following: 1. A goodwill warranty exception or partial/full coverage of the transmission repair cost, in recognition of our long-standing loyalty and the apparent prevalence of this issue across multiple vehicles. 2. An acknowledgment of the reported pattern of transmission failures in the 2019 Highlander, and whether Toyota is investigating or plan
The contact owns a 2019 Toyota Highlander. The contact stated that while attempting to start the vehicle, there was an abnormal grinding sound coming from the vehicle. No warning lights were illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed with transmission failure. The independent mechanic replaced the transmission fluid; however, the failure reoccurred. The vehicle was towed back to the independent mechanic, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The contact was informed that parts were on back order. The manufacturer was made aware of the failure, and a case was filed. The contact was advised to contact the federal safety agency Hotline to report the failure. The failure mileage was approximately 128,669.
At 138,000 miles my 2019 Toyota Highlander's transmission failed. I noticed a whining sound when I pushed on the accelerator, so I scheduled a service appointment to have it looked at. The day I brought it into the mechanic it began stalling at stop signs. I was driving my children to school when the vehicle began stalling, fortunately I was able to get it looked at that day. My local mechanic diagnosed it as a failed transmission having to do with something inside the transmission. I called Toyota and they said in order to qualify for support through their service program I needed to have the vehicle diagnosed by at a Toyota dealership. I had the vehicle towed to the dealership, where they too confirmed the transmission had failed due to something inside the transmission, which they diagnosed with a telescope. They quoted me $12K for a new transmission! I had routine maintenance performed throughout the life of the vehicle, primarily at the Toyota Service Center. Just 20 months prior to this happening I had the suggested transmission services completed at the dealership. The only services I had completed outside of the dealership over the last 20 months were regular oil changes and tires. The transmission in my 2019 Highlander is the same failed transmission as the ones in the 2017-2018, which Toyota issued a bulletin on, the same transmission Toyota has received numerous complaints about. The same transmission with hundreds of other customer's have filed incident reports on. The transmission they knew was problematic yet continued to put into new vehicles. I've been a loyal Toyota customer, this is my 5th Toyota. I can't believe that there is nothing Toyota is willing to do to support their customers. I thought Toyota prides itself on being a trusted brand with loyal customers, because they make vehicles that last and take care of them when they don't. I was wrong.
My Wife drove to work yesterday with no issues. After her shift she stops at the local gas station by her job, she puts the car in park but the car continues to roll forward( as if it was in neutral). Applies the brake and puts the E-brake on(car is now stationary). Puts in some gas, turn car back on, puts in drive and the car is makes a grinding like noise. We get the car towed home, jack it up, drain the fluid. The color of the fluid was darkish but still had a reddish tone to it, very slight sparkle look to it..didn’t see or feel any metal shavings to it.. highly confused on what failed for the transmission to be like that. Haven’t gotten it to the shop yet but a lot of research is showing something internal. No leaks, maintenance has always been serviced on time.
Transmission. Taken to dealership immediately. Notified that the transmission was going to have to be replaced. Notified there were no transmissions available or re-manufactured transmissions available, that our warranty was up 3 months prior to this date and we would have to spend in the range of $8500-$12,200 to get it fixed when a transmission was available. Warranty company did decide to cover some of the cost, but we were out of pocket almost $4000. This problem did not gradually appear, it was instant on the date the incident occurred. Filed a complaint with Toyota, they will not take responsibility and reimburse us any money. This should not be a problem with a Toyota with this many miles on it and they should take responsibility.
Rough switching between gears since purchase; Whining noise in transmission when pressing on the gas.
UA80 transmission problems like everyone else. Just paid it off and it’s under 100k and the transmission gave out. It’s $11k to fix it. I have it l the proper maintenance at Toyota.
My 2019 Toyota Highlander started making a whining noise from 0mph to 40mph-- and at times would shift hard. I took it to first mechanic who stated it was definitely a transmission issue. I took it to a transmission shop who also confirmed it was a transmission issue. I had vehicle towed to Toyota Dealer who performed a Multipoint Inspection and vehicle was placed on a scanner. The codes indicated "internal failure" on transmission and quoted me $10,500 to remove and replace. Parts are backordered for 8 weeks+. Current transmission is only at 63,000 miles and I am the 2nd owner.
I heard Whining Noise from Drivetrain side under Engine Room first time about a month ago. There is a possibility sure It was generated early that Noise longer than when I heard it. and I visited Toyota Dealership Vacaville CA about this issue, Requested to Diagnosis my Highlander 2019 XLE Gas type Vehicle. Technician said, "FOUND WHINE COMING FROM TRANSAXLE ASSEMBLY INDICATING INTERNAL FAILURE". Service Advisor recommended to replace "UA80E TRANSAXLE ASSEMBLY + TORQUE CONVERTER AND RECHECK". And I found Issue about There is a Document (TSB 0008-21) about this my Highlander 2019 XLE. I did not receive any information or recall or contact from TOYOTA until When I realized it.
Transmission began making high pitch whining sound with hard shifting to second gear. Within one year the transmission completely went out and was stuck in third gear.
My wife was driving here Highlander at freeway speeds when the vehicle started slowing and would not respond to the throttle. No warnings lights. It would drive but not accelerate to any reasonable speed. She pulled off the freeway and found a parking lot to test, restart car, etc. Again, no warning lights. Once in park, the vehicle would not shift into gear but only revved. The vehicle could not be driven and towed to a Toyota dealer and after a number of tests, it was diagnosed as a blown transmission. It was replaced at great expense. I do not know what the dealer did with the transmission but it was not tested. The safety issue is the sudden and expected loss of power/drive train on a freeway. The vehicle has been well maintained. At 100K, plugs and transmission fluid were replaced. Although the vehicle had around 130K miles, the transmission should not have failed in my opinion.
High pitch wine when accelerating
Transmission began making a whining noise around 70,000 miles. Transmission completely failed at 90,000 while driving on the highway and lost all forward gears and neutral. Only reverse gear works.
Transmission failed at early miles around 90k
Ua80 transmission failed.
I have been hearing a high pitched whirling noise. I took it to my dealership and the diagnostic report said it was an internal transmission problem. They said there was no code identified when they ran the diagnostic test, but they could also hear the noise. There were no other symptoms of an issue other than the noise I heard. I have done all scheduled maintenance for this car since I leased, then purchased it in 2019. When I researched the issue further, I found that vehicles from 2019 are known to have been built with faulty transmissions. I did not know this at the time of purchase.
The contact owns a 2019 Toyota Highlander. The contact stated that while driving at various speeds, there was an abnormal whining sound coming from the transmission. Later, while the contact’s wife was driving approximately 50 MPH, the vehicle went into LIMP Mode and decelerated unexpectedly. The contact diagnosed the vehicle and determined that there was a failure with the torque converter. The local dealer was notified of the failure, but no assistance was provided. The vehicle was not repaired. The manufacturer was not yet notified of the failure. The failure mileage was 128,000.
I’m concerned that my transmission was defective. My vehicle has 94K miles and was told by dealer I needed a new transaxle. We have never used our vehicle to tow or ever been stuck. It just doesn’t make sense why it would be defective. I was able to locate a Toyota bulletin regarding this.
