2026 Toyota Corolla Cross

The vehicle has experienced intermittent loss of power/acceleration when taking off from a stop. When the accelerator pedal is pressed, the vehicle sometimes does not accelerate normally or has substantially reduced power. This creates a safety concern because the vehicle may not accelerate as expected when entering or crossing traffic or in other situations where predictable acceleration is necessary. This has been happening off and on for several month. Around the same time, the vehicle's fuel economy decreased significantly. The vehicle had previously averaged approximately 37 MPG and is now averaging approximately 22–25 MPG under generally similar driving conditions. The vehicle was taken to an authorized Toyota dealership for inspection. The dealership was unable to identify a mechanical problem and reset the vehicle's computers. I was told the reduced fuel economy could be related to the computers relearning my driving habits. After the vehicle was returned to me, the loss-of-power/acceleration condition occurred again, so the issue remains unresolved. There have been no warning lights or dashboard messages associated with the loss of power. The specific component or cause of the malfunction is UNKNOWN. The vehicle is available for further inspection. Toyota corporate has also been notified and has opened a case regarding the unresolved condition.

My vehicle is subject to Toyota Safety Recall 25TA15 (NHTSA Recall 25V869) involving a loose inverter bolt. Toyota dealership has retained possession of my vehicle since February 23, 2026. As of June 22, 2026, the vehicle has been out of service for more than 120 days. Toyota has failed to provide a repair date, repair timeline, or meaningful resolution despite multiple contacts, a certified mail notice, and attorney involvement. Toyota Case Number: 260323003356.

The contact owns a 2026 Toyota Corolla Cross. The contact stated that while driving at various speeds, the vehicle failed to immediately accelerate while depressing the accelerator pedal. The contact stated that the failure had occurred while driving up an incline and while driving on a flat road surface. The vehicle was taken to the local dealer who was unable to determine the cause of the failure. The manufacturer was not yet contacted. The failure mileage was 4,100.

on the freeway after around 10 miles a vibration starts at 70mph and up to 80mph, it gets worse, its from the rear, you can feel it in the steering, through the floor, and seat, over 80 the whole car is one constant resonating vibration, tires have been replaced and conformed ok. Toyota are not doing anything to resolve the issue, and will not drive it as I request, and will not invite me to drive along with them.

The component that has malfunctioned is the hybrid inverter assembly, a loose internal bolt within the hybrid propulsion system. This vehicle is currently held at Fred Haas Toyota Country (Houston, TX) and is available for inspection upon request. My safety and the safety of the public are at risk because, as stated by the recall notice given on December 16 2025, this defect involves a bolt in the hybrid powertrain that "can become loose and could lead to a loss of motive power or could lead to a fire when the vehicle is on." The safety risk was confirmed by Fred Haas Toyota on March 6, 2026 and while there is no formal "Stop Drive" order, the dealership agreed to ground the vehicle and lend me a rental. As of today, March 28, 2026 there is still no remedy despite Toyota saying they "estimate the remedy can be available in the 1st quarter of 2026." Since my vehicle is currently in possession of the dealership, I am not sure if they have inspected it. Before I gave my car to Fred Haas Toyota Country I did not see any warning lights or messages, but the risk was still there (NHTSA 25V869000). My vehicle has been out of service for 22 days with no estimate repair date or remedy announced and the manufacturer has failed to provide a comparable loaner and has been unresponsive to my calls and messages. I am reporting a failure to remedy a known safety defect in a reasonable timeframe and am requesting an investigation into this delay and assistance with an appropriate rental or vehicle repurchase.
