2022 Toyota Highlander Powertrain & Transmission Problems

Noticed a sound coming from the car. I took it to the dealership which they said I would need my transmission replaced. They could only get me a refurbished one, which after parts and labor, it would cost 10,000 dollars. Upon talking with the technician, the transmission my car uses has been known to be faulty and having issues, usually after the warranty. So much so that Toyota did a recall on previous car years to extend the warranty for the transmission. The technician said they are replacing them often, which is why the supply is so low. These transmissions are the ones Toyota has been using since 2016, which have had many defects and causing issues. If this was known for years, why did Toyota continue to use them?

To Whom It May Concern, I am submitting this complaint to report a serious mechanical issue involving the transfer case on my 2022 Toyota Highlander. This problem raises concerns regarding the safety, reliability, and overall performance of the vehicle. While driving, I began hearing a grinding noise coming from the vehicle. Concerned, I brought the vehicle to an authorized dealership for a diagnostic inspection. I was informed that there is a transmission-related issue and that the vehicle requires a transfer case replacement. At the time of diagnosis, the vehicle had approximately 77,000 miles and has been primarily driven locally under normal conditions. This type of major drivetrain failure at such mileage is unexpected and concerning, especially given that the vehicle has been properly maintained. The failure of a critical component such as the transfer case can significantly affect vehicle control and drivability, posing a potential safety risk. This raises concerns about a possible defect in the drivetrain system or a broader issue affecting similar vehicles. I respectfully request that this matter be investigated to determine whether this is an isolated incident or part of a wider pattern. If necessary, appropriate corrective actions should be taken to ensure consumer safety. Thank you for your attention to this matter. I am available to provide any additional documentation, including service records and diagnostic reports, upon request.

I am reporting a premature transmission failure on a 2022 Toyota Highlander LE at approximately 85,000 miles. The vehicle began exhibiting a whining noise. When brought into the Toyota Dealership, I was notified that it needs a full transmission replacement. The vehicle was inspected by an authorized Toyota dealership, which determined that the transmission has failed and requires full replacement at an estimated cost of approximately $9,400. There were no warning lamps or messages of the problem prior to the failure. A transmission failing at this mileage creates a significant safety risk, especially when merging into traffic, accelerating from a stop, or maintaining highway speeds. This vehicle has been regularly maintained, with service performed through authorized Toyota dealerships. Despite this, Toyota has declined to provide assistance for the repair. This has caused a massive financial stress and strain. There is a documented pattern of similar transmission failures involving Toyota Highlander vehicles equipped with the 8-speed automatic transmission (UA80 platform) across multiple model years.This appears to be part of a broader pattern of premature transmission failures that may indicate a defect affecting vehicle safety. The consistency of complaints across multiple vehicles and model years suggests this is not an isolated incident. I am requesting that NHTSA investigate this issue for potential safety defects and determine whether further action, including recall or manufacturer accountability, is warranted.

My 2022 Toyota Highlander experienced transmission-related issues that affected the vehicle’s performance, reliability, and overall value. These problems caused inconvenience, safety concerns, and additional stress, and in some cases required diagnostic visits, repairs, or time without use of the vehicle. As a consumer who purchased the vehicle with the reasonable expectation of dependable operation, I believe compensation is warranted for the diminished value, disruption, and potential repair costs resulting from this defect.

early transmission failure and whining at 40,000 miles

AUTOMATIC TRANSAXLE WHINING FROM 35MPH-45MPH ACCELERATION. Needs to be replaced this is the third vehicle this week the dealership said had the same issue.

Transmission failed at 63,000 miles, new transmission was installed.

Transmission failed at 75K with no warning lights or prior evidence.

I had been driving my 2022 Toyota Highlander XLE with 46k miles that I just got for about two weeks, so about 10 days out of the 14 i actually drove it from home to work and back home. Within those 10 days driving the SUV, 8 mornings and one afternoon the highlander engine had issues accelerating and shifting gears. Basically when pulling out on to a highway from a side street coming down a hill when pressing the gas to enter the highway and flow of traffic the engine stuttered from zero to 20mph causing the entire SUV to jerk repeatedly and the gears would have issues shifting from first to second. I had to let my foot off the gas pedal then press again repeatedly as the SUV kept jerking trying to accelerate forward stuck no more than 20 mph for 30 seconds then started to even out and climb up after a minute. I have caught this on video twice. This has caused me to hold up traffic on the highway behind me with no where to pull off because my particular side street comes out from a gulch cliff side. No check engine lights came on each time. I took it to an auto shop that did a minor test drive and suggested it go directly to Servco Toyota as it should have powertrain warranty on it still and they believed it was a fuel pump issue. The issue did not happen with this auto shop but I showed them the video. I scheduled an appt at Toyota and it is with them now. They did 2 test drive but could not replicate the issue and could not see any codes coming up. I opted to leave the vehicle with them to do more test drives where the issue has happened as I do not feel safe driving it and the manager also said they did not feel safe having their techs drive it so the manager will do it. Without check engine light/code they are saying they cannot check the fuel pump or do anything else but will try to do more test drives to replicate the issue. I have seen numerous Reddit, facebook group posts, and a petition about this same issue but no official recall or word from Toyota.

Four days ago, engine started making a whining noise when accelerating, especially in lower gears. No warning signs. 2022 Highlander Platinum is 3 years old, 80K miles, out of warranty; no extended warranty purchased due to historical, stellar Toyota reliability. Toyota service department at Toyota dealership today said whining is due to a bearing issue within the transmission (my personal mechanic inspected and said that is also likely) and cannot be repaired. Transmission could last another 10K-20K miles they said, before it becomes undrivable or just drops, causing a potential safety issue. Net, the entire transmission needs to be replaced to the tune of $9186. Just shocking.

The transmission began making a whining noise at about 70,000 miles. It gradually became more noticeable. We had recently completed a thorough service, including transmission fluid exchange at 68,538 miles at a Toyota dealer. In March 2026 we took it to a Toyota dealer at 75,196 miles to report the noise and the dealer said the noise was coming from the transaxle and advised replacing the transaxle, which will require replacing the transmission. This was confirmed by a second Toyota dealer a few weeks later. Upon further research, it is clear that this is a significant safety issue and I will need to expend between $6k - $8k for repair from an independent shop and at a much higher expense if done through a Toyota dealer.

Car developed a whining noise coming from transmission at 63,000 miles. Known manufacturing defect that will lead to transmission failure. No recall issued and Toyota would not extend warranty. I do not feel safe driving the car pending a transmission failure. Toyota’s solution is to replace the transmission at a cost of $9000.

About 4 weeks a go i started hearing a whining noise from my Highlander. Thinking it was a belt we replaced. Whining continued to get worse only on acceleration. We are at 88,000 miles and it is now at Toyota getting a new transmission. Is there not something that can be done about this? I have read thousands of articles that show the UA 80E/F transmissions that are in the 2021-2022 models are junk. Luckily we bought a Toyota VSA and it is covering it. What about after 100,000 miles. Whats to say after another 80,000 it won't go out again which will cost me the $10,000. When the dealers put new transmissions in these vehicles are they using the same parts for the UA 80 E/F or the upgrade parts that fixed the 2023? If we have a VSA it should extended a year past the 100,000 mile mark because of the issue or they should have to replace them completely to match the 2023 models.
