Toyota Grand Highlander

2023 Toyota Highlander Hybrid Regenerative Brake Transition loss of brake pad pressure resulting in acceleration of the vehicle under downhill conditions. Have momentarily experienced the loss of braking frequently during braking when going downhill. This results in the vehicle gaining speed during this 1 or 2 second period before braking returns. In one case it allowed our car to get dangerously close to the vehicle ahead of us but fortunately I was able to push the brakes harder to prevent…

I have a 2024 Toyota Grand Highlander (FWD Gas) with about 37,000 miles and had 2 wheel bearings fail - front right and rear right. I noticed a constant humming noise starting around 20-25 mph that increased with vehicle speed. Thinking it was tire noise, I replaced all 4 tires, and the sound was still present. The dealership first replaced the right front bearing, and when they drove it after the repair, they noticed the sound decreased but did not eliminate the noise, and they further…

ABS actuator/accumulator issue on 2006 Toyota Highlander hybrid limited. Internal component failure there are recalls on others but not this particular year. Was driving along hit the brakes and got hard pedal. Yes there were other indicator lights on including the VSC system and traction control I came to an intersection and I couldn't stop I couldn't even kind of stop it was all hard pedal were before it was normal as if there wasn't an issue. I've done a lot of research and I've seen a lot…

The factory paint on my 2015 Toyota Highlander, Blizzard Pearl (Toyota code 070), is delaminating from the primer. The base coat lifts and peels in sheets, starting on the roof, fender, and pillars — the panels with the greatest UV exposure. There has been no collision, repaint, or chemical damage; this is spontaneous adhesion loss between the factory base coat and primer. First noticed 5/5/2026 at ~137,193 miles, it has spread across the roof and pillars, with the largest piece so far (~4x2)…

Rodent damage to plant based wiring to Engine Harness A and valve vacuum hose. Cost $1700 and 2 repairs.

Vehicle is experiencing a distinct, high-pitched mechanical whine or grind sound from the transmission during acceleration that increases in pitch with vehicle speed. The noise does not happen while cruising or coasting. This symptom aligns directly with Toyota Technical Service Bulletin T-SB-0008-21 ('Whine or Grind Noise From Transmission'). I am concerned about a premature, catastrophic internal bearing or gear assembly failure of the UA80 8-speed transmission while driving at highway…

My transmission started to have a noticeable whine at 53k miles. It became noticeably louder during acceleration. It was diagnosed at the Toyota dealership as a failing transmission. My vehicle was a few months out of warranty. I was told to contact Toyota corporate to ask for assistance. I was told since I did not have a service record at the dealership, they would deny my claim. I advised them the transmission was a sealed unit with no dipstick. My vehicle has been meticulously…

My vehicle has a recurrent issue with failing front axle assemblies. The vehicle experienced rotational clicking and had both from axle assemblies replaced around 20,000 miles. Around 40,000 miles the clicking returned and toyota has refused to replace the failing axles again. I currently am at 63,000 miles and I won an arbitration case regarding the axles. The arbitration decision ordered toyota to replace the axles and determined that the parts were defective and covered under warranty. …

While conducting independent research, the contact identified Technical Service Bulletin: T-SB-0028-25, which was associated with the…

My 2019 Toyota Highlander has the same UA80 transmission that Toyota was required to fix under CUSTOMER SUPPORT PROGRAM ZJC, which covers 2017-2018, the transmission has the same whining noise and shifting issues. Toyota must accept responsibility for their manufacturing error where the washer tab was not bent properly, allowing a nut to loosen leading to the whining noise. I expect the NHTS to require them to cover their 2019's as well, as a consumer we are getting screwed here.
