2023 Toyota Highlander problems

“Rear Power Lift Gate Struts continue to malfunction. Sometimes works, Sometimes Partially Works. My vehicle currently has 40,000 miles and according to Social Media and AI this has become a large Problem for a large number of People.”

“Ongoing severe engine surge after coasting while braking lightly during moderate downhill drives on pavement. It happens consistently with different drivers at speeds between 25 to 45 mph. The surge can cause the vehicle to lurch forward enough to move the vehicle forward suddenly, and rapidly to other cars ahead. This is an unpredictable issue, but occurs multiple times daily. Very concerning for everyone at risk in the vehicle. This issue was presented to several Toyota dealers in the San Diego (Carlbad, CA) and Temecula, CA areas during routine servicing during new car regular servicing up to 36k mi. It was documented at those dealers 4 times. They could not reproduce it until the 4th service appt at Temecula, CA Toyota. Toyota has a remedy for previous years' models of Highlander Hybrid, which was a software upgrade to the hybrid braking/engine system. But not the 2023 year. Yet.”

The contact stated the manufacturer exceeded a reasonable amount of time to provide a remedy for the recall. The manufacturer was notified of the issue.”

The concern was reported to Toyota/dealer multiple times. At first, the odor was intermittent and difficult to duplicate, but the problem continued after repeated dealer visits. The fuel smell was later duplicated/confirmed while the dealer was open, before approximately 60,000 miles, but the vehicle was still not properly repaired. The odor has continued and recently occurred multiple days in a row. The smell has been noticed around/inside the vehicle and creates a safety concern because gasoline odor may indicate fuel vapor leakage or a fuel-system problem. Possible sources could include the fuel tank, fuel pump module or seal, filler neck, fuel lines, EVAP system, charcoal canister, purge valve, injectors, fuel rail, or another related fuel-system component. The vehicle has been inspected by a Toyota dealer multiple times, but the cause has not been identified or corrected. No warning light has clearly identified the source of the problem.
