2024 Toyota Prius problems

Filed Oct 5, 2026 · Lights · MA

Description of Safety Defect: I am reporting an uncorrected factory design defect in the 5th-generation Toyota Prius (2024 model) that constitutes an immediate and ongoing daytime driving hazard. Under standard operation, whenever the vehicle's headlights are activated during daytime hours—conditions legally mandated by Massachusetts state law, such as during rain, heavy fog, snow, dusk, or dawn—the driver's 7-inch Multi-Information Display (MID) speedometer cluster and the central multimedia touchscreen plunge into an aggressive, low-brightness night profile. When this occurs in daylight ambient environments, heavy glare can completely wash out both digital screens, rendering the speedometer, safety alerts, warning lights, and navigation maps illegible to the driver. Manufacturer Response: The vehicle's digital 'Day Mode' software toggles and the lower-dash manual instrument panel adjustment buttons completely fail to override or un-dim this behavior when headlights are active. System reboots and ambient sensor inspections do not change the state. I have formally presented this vehicle to an authorized Toyota dealership and directly escalated the issue to Toyota Motor Sales Corporate. Both parties have officially stated that the vehicle is 'operating as designed' and refused to issue a technical remedy or calibration update. Safety Risk: By hard-coding an un-overrideable night-dimming profile to the headlight circuit, Toyota has built an active safety hazard. Drivers are forced into an unacceptable compromise: either drive illegally with headlights OFF during a daylight rainstorm to be able to read their speedometer, or turn headlights ON to comply with the law and drive blind to their actual traveling speed, warning lights, and driving telemetry. This extreme driver distraction severely increases the probability of an accident.

My safety and the safety of 6,031 passengers/riders were put at risk when Lyft's Flex Drive rented this vehicle to me as a rideshare driver for one year. They admitted yesterday upon confronting them in person that they were aware of the recall and decided to not inform me. The company deflected responsibility onto me in several ways and even laughed in the back of the building. There was nothing funny about putting my life at risk and the lives of other people. It is a breach of agreement for me to drive an unsafe vehicle. I trusted that I rented a vehicle that was safe. Lyft is a rideshare company that owns FlexDrive. Flex Drive rents cars to Rideshare drivers in [XXX]. There are nearly 4 thousand vehicles rented to Lyft drivers in [XXX] right now. The vehicle just stopped working on XXX due to a Hybrid Malfunction and is located at Toyota Camelback currently.

Since owning this car, there is a mildew odor coming from all 4 doors in the window slot. Clearly, water is collecting in the door insulation and growing mildew presenting a health issue. The dealer cleaned one of 4 doors and returned the car. Whenever the car is washed or in the rain, this issue happens. In checking on line, this is not an isolated incident. Prius models from 2024-2026 are experiencing the same issue. Again, this is not merely an inconvenience, it seems to becoming a health related issue

I am writing to report a serious safety incident involving the rear seatbelt in my 2024 Toyota Prius, and to request that Toyota investigate this condition as a potential safety defect affecting other vehicles. On XXX at approximately 7:08pm , my daughter, age [XXX], was seated in the rear right seat of the vehicle. We were traveling at approximately 35 on city street in FAIRFIELD CA. She was belted in using the vehicle’s factory lap‑shoulder belt. Upon arrival, she adjusted the shoulder strap to gather her belongings and the seatbelt wrapped around her waist and cinched down to the point that it became dangerously tight and she was in severe pain. The belt continued to retract and would not loosen. Attempts to unbuckle the latch and to create slack by feeding the belt back into the retractor were unsuccessful. The belt remained locked tightly around her waist and could not be released. Because of the extreme tension and the location of the belt, we were unable to free her and ultimately had to cut the seatbelt to prevent further injury. This incident left visible marks/redness around her waist, and it presented a real risk of abdominal injury and impaired breathing. I have attached photographs taken immediately before the belt was cut that show how the belt path, seat back, and retractor configuration allowed the belt to wrap around and entrap my child. I am concerned that this may reflect a design defect in the rear seatbelt system and that other children could be similarly trapped and injured.

After the car dealership completed the first tire rotations, at 30,000 miles I rotated the tires to find severe inner tread wear on the tires where the inside of the tire was wore to the sidewall while outside portion was intact. I took the vehicle to an independent shop and the right rear suspension/tire was out of specifications on camber causing said tire wear. Toyota did not manufacture the car so that camber could be adjusted. An aftermarket kit was purchased to be able to compensate for the lack of adjustment. This is a safety concern as if a person does not rotate every 5,000 miles it will lead to tire failure at highway speeds. This is a common problem while researching forums. I have contacted the manufacturer and was given a generic response. There are reports with documentation with tire failure as early as 11,000 miles. Toyota needs to be held accountable and make a remedy for this instead of offering consumers a run around and blame hitting pot holes or on tire manufacturers, when it is clearly a suspension limitation. Thank you.

I was driving my 2024 Toyota Prius and was involved in a front-end collision. The impact was strong enough to cause significant front-end damage, but the front airbag did NOT deploy. I was wearing my seatbelt at the time. This is a serious safety concern because the airbag should have deployed in this type of frontal impact. If the crash had been worse, I could have been seriously injured. I believe this may be a safety defect in the airbag system.

On August 15, 2025, I was backing my vehicle when the rear view camera screen went blank, providing no image of what was behind me. With no warning and no image, I collided with a rock and landscape, causing damage to the rear of my vehicle. At the time of this incident, my vehicle had an open, unrepaired safety defect under Safety Recall 25TA13, which specifically addresses the condition that the rear view camera image may freeze or not display while reversing. I was not aware the recall existed at the time of my accident, and the recall remedy was not completed on my vehicle until February 12, 2026 — nearly six months after the incident. I filed a claim with Toyota Motor North America. They inspected the vehicle on February 11, 2026, found the camera functioning at that time (after the recall had since been remedied), and denied my claim. They cited owner's manual language advising drivers not to rely solely on the backup camera, but did not address the fact that the recall was unrepaired at the time of the accident. Additionally the parking collision warning and automatic braking should have engaged. The rock impacted the car right near one of the car cameras....so the collision warning and braking should have engaged. I am filing this complaint because I believe the unrepaired recall directly caused my inability to see behind my vehicle, and that Toyota's delay in notifying me and completing the remedy contributed to this incident. I am requesting that the federal safety agency review whether Toyota's notification and remedy timeline for Recall 25TA13 was adequate, and that this incident be added to the record of complaints associated with that recall.

The way the accelerator pedal sensor is positioned allows for water infiltration from wet carpet / tracked in snow and water. The component is available for inspection upon request. Once sufficiently saturated the sensor fails, and ceases function DURING VEHICLE MOVEMENT. The problem is reproducible but has not been confirmed as a pattern of failure by the dealership. As far as my recollection, the manufacturer hasn’t inspected the part. P2138 is the associated check engine code and the vehicle enters limp mode DURING TRAVEL. The check engine light (and subsequent problems) first appeared while in traffic on 2/10/2026.
