| Mar 2026 | FUEL/PROPULSION SYSTEM | Check engine light came on without warning, car started losing power, idling roughly, stalling out, and not wanting to start. Had my battery, alternator, and starter checked and they are all fine. Diagnostic test showed it was to do with how much fuel/air the vehicle is getting. The check engine light goes off and on as I’m still having to try and drive my vehicle to and from work due to not having other transportation. | Crash: No Fire: No | Unknown |

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".

| Mar 2026 | POWER TRAIN | 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. | Crash: No Fire: No | Unknown |
| Mar 2026 | UNKNOWN OR OTHER | Transmission whining sound | Crash: No Fire: No | Unknown |
| Mar 2026 | ELECTRICAL SYSTEM | Sporadically, when starting up the vehicle, from the overhead console, it emanate a loud, ear piercing sound that is painful to one's ears. Apparently, this is a KNOWN issue with 2019 Toyota Highlanders in the Limited Platinum trim level. This issue has been presented to the dealership numerous times (DARCARS Toyota Frederick) with their claim they could not recreate the issue. I have provided video evidence but still no action was taken. Now out of warranty, it occurs more frequently now with this piercing noise. | Crash: No Fire: No | Unknown |
| Mar 2026 | POWER TRAIN | 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. | Crash: No Fire: No | Unknown |
| Mar 2026 | POWER TRAIN | 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. | Crash: No Fire: No | Unknown |
| Mar 2026 | ENGINE | Our 2019 Toyota Highlander currently has 54,605 miles. In August 2025, when the vehicle had 50,236 miles, we brought it to the Toyota dealership to address a whining noise coming from the transmission. At that time, the vehicle was still under the manufacturer’s warranty. The dealership performed a transmission service during that visit. Within the following weeks, however, the whining noise returned, and the vehicle began experiencing hard and delayed shifting. Our children and grandchildren have recently moved to Washington, and we had planned to drive there to visit them. Unfortunately, we are now reluctant to drive the vehicle due to safety concerns, as we have been advised that the transmission may be failing. The dealership has now recommended a full transmission replacement. Because the original concern was reported while the vehicle was still under warranty, we believe the issue should have been properly diagnosed and resolved at that time. However, the problem was not addressed, and the vehicle is now outside the warranty period, with Toyota declining to cover the cost of the replacement transmission. Given that the problem was first reported while the vehicle was under warranty, we are requesting that Toyota reconsider covering the transmission repair or replacement. | Crash: No Fire: No | Unknown |

| Feb 2026 | POWER TRAIN | 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. | Crash: No Fire: No | Unknown |

| Feb 2026 | POWER TRAIN | While driving, my vehicle experienced a sudden transmission failure. The vehicle began to lose power and was unable to shift properly, making it difficult and unsafe to continue driving. I had the vehicle inspected and the transmission is currently being rebuilt. The mechanic performing the rebuild has stated that the failure was caused by a faulty build and a manufacturer defect, not normal wear and tear. I am currently awaiting written documentation from the mechanic confirming this, which will be submitted once received. | Crash: No Fire: No | Unknown |
| Feb 2026 | POWER TRAIN | My Toyota was just in the shop for 100,000 mile service and investigation of whining noise upon acceleration. Was notified that the transmission needs replaced and will cost over $7500 . Transmissions are supposedly on back order. Upon further investigation, discovered there is a known issue with 2017-2019 Highlander transmissions that Toyota failed to issue a recall and failed to notify owners of these models. Repairs have not been made as transmissions are on backorder due to the magnitude of the issue. | Crash: No Fire: No | Unknown |
| Feb 2026 | POWER TRAIN | On Sunday, February 1st 2026 during sub-freezing temperatures The vehicle's 8-speed automatic transmission (UA80) experienced a complete mechanical failure while driving. This resulted in a sudden and total loss of vehicle propulsion, requiring the car to be towed. Prior to the failure, the vehicle's AWD system indicator light was illuminated. The failure was diagnosed by Alexandria Toyota on February 3rd of 2026 as a catastrophic internal transmission failure requiring full replacement of the transmission Assembly with cooler (see attached quote). This defect causes an unreasonable safety risk by potentially stranding the vehicle in moving traffic or causing a crash due to unexpected loss of power. | Crash: No Fire: No | Unknown |
