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.

The contact owns a 2017 Toyota Highlander. The contact stated that when the vehicle was taken to a dealer for routine maintenance, the dealer informed the contact that the rear main seal was leaking and needed to be resealed.

-- What component or system failed or malfunctioned, and is it available for inspection upon request? This report is regarding a premature transmission failure in our 2017 Toyota Highlander equipped with the UA80F 8-speed automatic transmission. Our highlander is currently stuck at High Tech Automotive in Wenatchee, WA 150+ miles from home after experiencing a transmission failure on the highway. -- How was your safety or the safety of others put at risk? During the transmission failure while driving on the highway the Check Engine Light came on as well as ABS light and vehicle went into a limp mode. The transmission failure and subsequent limp mode rapidly decreased our speed while traveling on the highway and forced us to limp the vehicle at low speeds across traffic putting ourselves and others traveling on the highway at risk. This vehicle has been well maintained and serviced in accordance with Toyota’s recommended maintenance schedule. Despite this, the transmission failed

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.

I drive a 2017 Toyota Highlander and am having issues with the transmission. The issues and poor craftsmanship on the UA80 8-speed transmissions. Toyota offered Technical Service Bulletins T-SB-0160-18, T-SB-0008-21, and a limited Customer Support Program (CSP ZJC). But very few VINs were included and there are tons of Highlander owners with this transmission facing $10,000+ repair bills for what is supposed to be one of the most reliable cars and car brands on the planet. This is very wrong. Toyota has not stood by its customers and have not done right by owners. Toyota needs to recall the transmissions and offer a remedy at no cost to the customer. This needs to be done now. It's completely unacceptable. Thanks for what you do and for reading! Appreciate you guys very much.

Vehicle shurtter cause toque converter issue with all Toyota Highlander

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.

The contact owns a 2017 Toyota Highlander.

The paint on the hood is flaking off. There is no reason other than the paint being defective for this to happen in this manner. We just noticed it today. 11/14/25

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.

Leaking fuel line due to deterioration of plastic liner in fuel line.

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.

My vehive has 122,000 miles...I recently received an airbag mafuction warning on the dash info system and to contact dealer. The dealer states this driver side airbag is now defective and needs to be replaced at a cost of $1100.00 The airbag has never been deployed. How is this noit covered under safety requirements on current vehicles? How do I know that the part was not defective when initally installed?

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.

Formal Complaint to NHTSA – Summary I am submitting this formal complaint regarding repeated mechanical and electrical failures involving my 2017 Toyota Highlander, purchased as a Toyota Gold-Certified vehicle with an extended Platinum Warranty. Despite strictly following Toyota’s maintenance guidelines and using only certified dealerships for all services, the vehicle has become inoperable multiple times, requiring five separate tows and resulting in repair costs exceeding $10,000. In June 2025, a Toyota dealership replaced the engine after diagnosing a warped head due to water pump failure. Following this, the vehicle began experiencing repeated charging system failures and electrical malfunctions. Multiple components—including the alternator, battery, and sensors—were replaced at another Toyota dealership based on ongoing issues, but the problems persisted. On September 2, 2025, a Toyota technician identified a missing ground wire nut as the likely root cause of these ele
