2019 Toyota Sienna Reliability Score & Common Problems

Owners report issues with the power sliding door on the 2019 Toyota Sienna, specifically noting that it malfunctions by detecting resistance and closing with excessive force, leading to potential injury. One complaint mentions an injury to a child and an adult due to this malfunction, highlighting a safety risk. Another complaint involves concerns about the frontal impact sensor not providing any alerts, despite being set to high sensitivity, which raises questions about its functionality. Mileage and timelines are not consistently mentioned, but issues with the power sliding door are noted after three years of ownership. These reports suggest potential safety implications, particularly with the sliding door's forceful closure.

Owners of the 2019 Toyota Sienna report issues related to the fuel/propulsion system, with common complaints involving fuel pump problems and fuel vapor smells. Multiple reports indicate hesitation and jerky acceleration, particularly at lower speeds, despite fuel pump replacements. Some owners also describe strong fuel odors both inside and outside the vehicle, which persist even after dealer inspections fail to identify a source. These issues often occur at various mileage levels, with some problems noted immediately after purchase. Safety implications are highlighted by concerns about potential fire hazards and the risk of sudden vehicle lurching leading to possible injury.

Owners of the 2019 Toyota Sienna report issues with the electrical system that include malfunctioning microphones linked to the SOS call button, inoperable liftgates and back-up cameras, and electrical shocks from the steering wheel and seatbelt. Complaints frequently mention symptoms such as a burning odor inside the vehicle, illuminated airbag warning lights, and discomfort from electrical shocks, particularly affecting the steering wheel and seatbelt. These issues are reported at various mileage points, with one complaint noting problems at approximately 72,000 miles. Safety implications are evident in the reports of inoperable safety features and electrical shocks causing physical discomfort. Potential buyers should be aware of these issues, especially concerning the functionality of emergency and safety systems.

Owners of the 2019 Toyota Sienna report issues with airbag deployment. Complaints frequently mention airbags failing to deploy during a side impact crash, as well as instances of spontaneous deployment without collision, leading to injuries and damage. In one case, airbags did not activate during a collision at approximately 30 mph, resulting in a severe jarring of occupants and shattered glass. Another owner describes all airbags deploying unexpectedly while driving at low speed, causing injury and broken windows. These reports involve vehicles with mileage around 52,200 km and within a few years of purchase, highlighting potential safety concerns for prospective buyers.

Owners of the 2019 Toyota Sienna report issues with unintended acceleration when the vehicle is in reverse, with one incident leading to a crash and resulting in an injury. Complaints frequently mention the vehicle accelerating independently despite the brake pedal being depressed, and in one case, the vehicle lunged downward when braking. These incidents occur at varying mileages, with reports at approximately 6,800 and 45,750 miles. Safety implications are significant, as the unintended acceleration has led to a loss of control and a collision, which may be a concern for potential buyers.

Owners of the 2019 Toyota Sienna report issues with the vehicle's exterior lighting, specifically the LED daytime running lights on the passenger side, where several LEDs either fail to illuminate or flicker. This problem is noted by an owner despite the vehicle being relatively new, purchased in late August 2019. While the primary focus is on lighting, another complaint describes a separate incident involving a stall and acceleration hesitation, though it is not directly related to the exterior lighting category. These issues may have safety implications, particularly the non-functioning daytime running lights, which could affect visibility. Potential buyers should consider checking the functionality of the LED lights and be aware of these reported concerns.
