2017 Toyota Highlander Power Train

I had problems in gear shift the car when start moving it’s go very slow it’s need about 1 minute to change the shift. The Toyota dealership recommended me to change the transmission with the cost $11,000

Transmission failed in May 2025, around 95,000 miles. Had to have entire transmission replaced. Shop said metal filings were found in the fluids, leading to the breakdown and need for full replacement. No other warning lights or lamps indicated a problem. A high pitched whining noise was the indicator, which then led to several visits to the shop, monitored the issue, changed fluids, but the transmission eventually failed. Transmission failed in May of 2025, it took 3 months for a new transmission to be built and shipped to the midwest for install in Aug 2025.

I own a 2017 Toyota Highlander with 6 cylinders (engine model 2GR-FKS). It has 107,000 miles. I brought it to my dealer for inspection and service, and noted that it was making a whirring/whining sound upon acceleration. There were no warning messages on the dashboard to alert me of any issues. The dealer reported back to me that the transmission was failing and quoted $11k to fix it. Upon researching this issue, I learned that this is a known problem with 2017 model Highlanders.

Purchased my 2017 Highlander in June of 2017. At 4912 miles noticed the transmission was slipping. Contacted the dealership and was told from an employee that in his 20 plus years he had never had a transmission do that. Took it to the dealership and it was the transmission. It was replaced under warranty. In January of 2026 took it to the dealership after noticing a weird whinnying sound when running. After running a diagnostic test I was informed that my transmission needed replaced again. It only has 72,426 miles. Was told that the transmission was on back order and when asked if safe to drive, told yes.

After less than a year of usage on a Highlander with 70k miles, the transmission began malfunctioning. The reverse function would work sporadically. The gears would shift only when using the power stick function and manually switching gears. The transmission would go into overdrive and once after an oil change the car came to an abrupt stop after traveling 25 mph hour.

Vehicle shurtter cause toque converter issue with all Toyota Highlander

Transmission when the car first starts up is slipping. No dipstick for checking Transmission fluid.

The transmission is experiencing harsh and sometimes delayed shifting and sometimes reduction of power. This can result in unpredictability when going from a stop and then crossing traffic. If the transmission fails while I am making an unprotected left turn it pups leave me vulnerable to side impact from on coming traffic. The dealer was able to reproduce the issue when I took it in and quoted me $11k for repair. Toyota is an aware of issues with this specific transmission (UA80) and issued a Service Bulletin for it. My transmission fell within the serial number range for replacement but didn’t pass the third gate for coverage related to a speed sensor issue. That said, there is massive back order on this transmission highlighting a much broader problem with the part. To answer the final question, I never saw a warning light.

Was on drive from work in 2017 toyota highlander XLE. Noticed low whining sound coming from transmission. Made appointment with toyota dealership. They identified transmission whine as requiring full replacement and projected to fail soon. Vehicle mileage was at 116k miles. There are no ua80 trans available in US and none coming in. Was told my VIN didn't qualify for CRP CJZ and TSB bulletin. The UA80 trans has known failure of this type. Replacement cost is 10K, use is dangerous, and failure is unacceptable.

TRANSMISSION ON THIS VEHICLE FAILED AND CAUSES SUDDEN DECELERATION CAUSING A SAFETY ISSUE. SUDDEN DECELERATION. YES, TOYOTA OF VERO BEACH HAS CONFIRMED FAILURE OF THE TRANSMISSION. NO, WARNING JUST FAILED THEN GOT ALL THE WARNINGS AND LIGHTS IMMEDIATELY THEREAFTER.

2017 Toyota Highlander XLE Why hasn’t Toyota issued a recall?! My transmission failed at 2AM on the Florida turnpike 140 miles from home, after a physically and emotionally exhausting day moving my daughter to college. I slept in my car 7 hours, scared, waiting to get towed. The closest shop that was open early on a Saturday was an hour away in the other direction and when I got there, they told me they wouldn’t be able to look at it until Monday. Pointless to pay 2 nights at a hotel, so I got an Uber to get a rental to get home. It wasn’t bad enough when I found out the cost to replace the transmission on a car with 96k miles (my Camry had 300k when I sold it), but even if I agreed to pay, the transmission is backordered, and it could be months. Months! I had to pay the diagnostic fee - completely understandable - and I needed it moved to avoid a $75 per day storage fee. AAA would tow it 100 miles, then $7.00 per mile. When I asked to speak with someone because I had the upgraded membership that provided 200 miles, I was told they wouldn’t cover any part of the tow because it was already at an auto shop. The least expensive option was to get a transport company ($300) to pickup and deliver the car to the local Toyota dealership. They’re anticipating at least 3 months, but they’ll pay for a rental if I agree to have them do the repair. Has Toyota fixed the issue, or will the new transmission likely to have the same problem?

Transmission whining, harsh shifting, delayed acceleration

Transmission intermittently allows the RPMs to double from 2,000 to 4,000 RPMs. It occasionally displays trouble codes, and exhibits a grinding, whirring noise. An Independent transmission shop confirms that it needs to be replaced. Toyota has issued a recall referred to as Customer Support Program ZJC, but their representatives claim that our vehicle does not qualify, even though the date and model of the transmission clearly Falla under their parameters.

Car suddenly began to slip out of gear and have difficulty shifting smoothly. After having car examined by 2 repair shops it was determined the UA80 Transmission needed replaced. Repair shop advised car was not safe to drive with this condition. Warning lights for Check Engine and Check AWD system and traction control came on at the same time as the slipping and rough shifting.

The transmission on my Highlander is making a whining noise. I took it to Blackstone Toyota Service for inspection, in Fresno, CA, after my own mechanic inspected it and told me that it was a transmission problem. Toyota told me that the transmission is going out and the car can quit on me at any time and is no longer safe to drive. But since it is out of warranty now they will not do anything to help me with this problem. There has been no warning lamp, message or other symptoms yet. After my service in Nov. 2023 i noticed a slight whine when i accelerated. I had a friend mechanic look at it and he said it could be just because the tires had been rotated. A couple of months ago the whine started on deceleration. I took it to Johnson Auto in Clovis, CA and they were the first ones to tell me it was in fact a transmission problem. I then called Toyota call center and was told that the vehicle needed to be inspected by one of their dealers, and then they could help me. I explained that I didn’t want to go spend more money on the inspection if Toyota would not do anything to help me, I already knew it had transmission problems. I took it to Blackstone Toyota Service Center and they confirmed that the transmission is going out, at only 7800 miles. I called the Toyota call center and was told that since it is out of warranty they will do nothing to help me with this problem. I told them the prior agent I had spoken to said that Toyota would help me. I was told they will do nothing else to help and there was no one else I could talk to about the transmission problems. I was told that they didn’t know of any problems with the 2017 Toyota Highlander and that there were no recalls. I told them that there were lots of complaints about the Toyota Highlander online and I was surprised that they didn’t seem to know anything about the Highlanders having transmission problems. Many people in my same circumstances with expensive repairs way too soon on their Highlanders.

My 2017 Highlander XLE AWD had complete transmission failure at 106,000 miles. Toyota has an extended coverage warranty for this but according to them my VIN number was not included even though it failed for the same reason as the recalled transmissions. Loud whining started around 100,000 miles on acceleration around 30mph and continued to get louder. From a dead stop it is very slow to accelerate and misses 3rd gear and jerks. There is a TSB out on this and the extended customer satisfaction extended warranty ZJC but they refuse to cover. I was also told by Toyota corporate that even if my VIN was affected they would not cover due to all maintenance not being done at a toyota dealership. I am the 4th owner and should not be penalized for this. My case number with Toyota is Toyota Brand Engagement Center Case 250416002071

Transmission failure causes vehicle to not accelerate in low gears. Toyota has a CSP for this issue on the same model year but this "Vin" Is not a part of it. This is a major safety issue.

Transmission failure requiring replacement. Known pattern failure from Toyota. Customer support program from Toyota does not cover all affected vehicles.

Known issue with the transmission assembly that results in a whining noise and eventually hard shifting and transmission failure. Known issue acknowledged by Toyota across this model and date, but they seemingly are only addressing some vehicles - and not others - with said known issue.

There is a toyota service bulletin for known transmission issues with this vehicle. I had noticed that my gears weren't shifting properly. The dealer checked vehicle and said transmission was bad, and that toyota would replace it, for free. However, the part would take one month to arrive. This all occurred on 1/9/2024. I was told by the dealer that Toyota would not cover a rental car while the part was on order, but only for the repair itself. The dealer told me the Toyota recommendation was to not drive the vehicle -- but other customers had done so until they received their parts for repair. I picked up my vehicle after work at approximately 7:15pm. While driving, the vehicle completely shutdown on me in a major highway miles from downtown Philadelphia, in a flooding rainstorm that produced nearly 4 inches of rain. If Toyota knows there is a problem with this vehicle and its transmission, then why is there no recall? And if I'm being told the I should not drive the vehicle, then why isn't it mandated or required for them to provide me a rental - especially since this is the fault of Toyota?

The contact owns a 2017 Toyota Highlander. The contact stated that the vehicle was parked but still running in a driveway on an incline. After exiting the vehicle, there were abnormal beeping and ticking noises detected, and the vehicle began to roll down the street. The contact and daughter were pinned between the door and the vehicle. The contact's daughter sustained injuries to her chin and teeth. The driver has lumps and bruises on her leg and back pain, but medical attention was not provided. The rear wheels were on the curb and hit a trash can, and the vehicle stopped rolling. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 70,000.

In city driving, vehicle began exhibiting slightly delayed shifting from 1-2 and 2-3. Downshifts from 3-2 seemed slightly rough. Approximately 5 minutes later when accelerating from a stop on an uphill grade, the shift from 2-3 was delayed (2nd gear disengaged, engine speed increase ~1000RPM, then shifted to 3 abruptly). At next stop, lower gears where not available. Vehicle seemed be in 4th(?) gear when accelerating from a stop. Very little power available. Had to engage hazard flashers and other vehicles navigated around our vehicle. Managed to limp car ~ 1 mile to home. Approaching driveway, Master Warning Light, Check Engine Light and 4WD Warnign light all illuminated. This issue created a loss of power that impaired the drivers ability to maintain a safe speed relevative to traffic. Had this issue occurred during high-speed operation, the vehicle may have been disabled in a high-risk area. Transmission appears to be unreliable.

2017 Toyota Highlander experienced delayed and rough shifting in 3rd gear. Safety of acceleration is affected, especially merging onto highways. Diagnosed with bad transmission on 12/26/2023 by Toyota service. There was no warning lamps or messages prior to failure. Unknown cause, car is regularly serviced per manufacturer recommendations by Toyota. Part on backorder for approximately 3 months.

Transmission lost power while driving and began to slip. Had to pull over immediately. Check engine light illuminated. Happened again several more times before I was able to take to dealer. Dealer was able to reproduce and diagnosed as transmission failure requiring replacement for $10k. Due to the low miles and age (6 years, 3 months) I requested that Toyota help cover costs which they declined to do. This is a dangerous situation and I believe Toyota should have fixed as goodwill.

Highlander shift issue 11/14/2023 On 11/14/2023, our 2017 Toyota Highlander, vin# [XXX] , upon driving the transmission decided on its own to disengage. Our Highlander stopped propelling itself in either direction. We had to manually push our vehicle into a parking spot and await the tow truck. Our Highlander is in mint condition with 71,400 miles on it. This was scary because the vehicle would shift on the shifter, but for some reason the transmission would not engage. The engine worked perfectly fine. We had the Highlander towed to the nearest Toyota dealer who pushed the vehicle into their garage and placed on a lift. The Highlander had no idiot lights on, no cable issues, fluid was fine per the Toyota Technician. The Toyota Tech placed the vehicle on their main computer and there were no error codes. The Tech reset the computer on the vehicle with a Toyota Master computer, and the vehicle started to work as normal. I consider this a huge issue and I thank God that my wife was not on the interstate highway when this happened.
