Multiple times a week in the summer my car will hesitate to go once I have stopped at a stop sign/busy four way intersection. When I push the gas the car doesn’t respond and hesitates for a long while before I can get the car to start moving again. The car will roll into the intersection after I take my foot off the break to go and it won’t do anything. It is terrifying and confuses other driv
... ers around me thinking that I am letting them go. This has happened upwards of 20 times since I have had the car. It happens only on hot days when the external temperature is above 80 or so degrees and happens when car is freshly started. It reliably happens when I go up a pretty small hill by my house about 1 minute after starting the car (even when it is coming from being parked in my garage). Joseph Toyota on Colerain in Cincinnati has not been able to reproduce the issue. I drive with two children in the car and it is so scary when it happens because I have almost been hit with them in the car many times now.Read more

Fog Lights (Rigid Industries Version) significantly shake during normal street driving conditions. Any minor bumps on the road cause a shudder like movement from the fog lights that is distracting while driving and potentially blinding to oncoming drivers as the lights flash up and down. Vehicle was taken to Beaver Toyota and inspected for this concern, the technician inspected the fog lights an
... d stated that there was nothing wrong. The vibration / shake from the fog lights is well documented as a concern in online forums, however, everyone seems to get the same response from Toyota. It seems other Land Cruiser owners with the same fog light package have no issues with shake while others have the same issue described above, making me believe that there is a defect with some models fog lights, the housings, brackets, or bumper assembly. This needs to be solved from Toyota, not only is it distracting while driving, it makes me want to not use the fog lights at all. For a $70k+ vehicle, the movement from the fog lights should not be "normal".Read more

The break pump for my 2013 prius is going out and is a known issue with Toyota. I contacted toyota and they have stated because it is past the extended warranty they can not repair it and aren't liable for it. I bought the car used and was unaware that it has been a known issue for years. The previous owner did not have it replaced as they were probably unaware as well. It is a highly unsafe issue
... and has caused my breaks to suddenly go our while driving recently with my toddler. It is also $3000-$5000 to fix it and is almost more than the cars value. I need help resolving this as it isn't "normal wear and tear" or a mileage issue. It is a known, very public defect that toyota has admitted and I have been able to easily find information on all over Google. The warning lights came on out of no where on the freeway today.Read more

I continuously have issues accelerating from stop in my max hybrid. the issue is particularly worse when it is warm out. I press the gas and the RPMs drop really low and I barely move through the intersection for a few seconds. Once it finally registers after a number of seconds, the RPMs rev up over 4000. It is very dangerous trying to proceed through an intersection and the car basically stalls
... when I press the gas. It especially concerns me that I have my child in the car with me and I worry when it is going to act up. I know others have experienced this issue and there was a TSB for 2024 models that had this issue. I have a 2025 and experience this issue. I have had toyota look at it and they said they cant do the TSB since it's bot for my VIN. A solution needs to be found for the the safety of myself and others.Read more

The car stalled on entering secondary roads from my own neighborhood. When it happens, I have pressed the throttle and the car stops moving forward. It takes 5-10 seconds before the engine picks up and the car moves. The first owner found the same thing and now as the second owner, it has done the same thing.

I have over 30k miles on my car. Over the period that I’ve owned it there have been a few, roughly 6, occasions where I’m trying to change lanes from a stop into quick traffic and my car lags 1-3 seconds in response to me pressing the gas petal. It happens infrequently and is not the normal response. Other times the car responds as one would expect.

Purchased size 265/70R17 tires (Michelin Defender LTX M/S2) exhibiting severe highway vibration immediately post-installation. The vibration persisted continuously for two years across every rotation, posing serious handling and steering risks. For two years, local shop staff gaslit the customer, claiming an "out-of-round" tire or casing defect was impossible to avoid warranty obligations. During
... a visit in front of store management, staff repeated the claim in front of management. The customer then presented real-time technical data from Google on the spot, forcing staff to admit casing defects happen. Despite this, management cleared the driver to leave, assuring the vehicle was safe to operate with an infant inside. To obtain objective proof, an authorized TOYOTA dealership inspected the vehicle. The dealer verified steering, suspension, and alignment were completely sound and documented the root cause in writing: "Found front left tire has casing deformation." When escalated to corporate executives—including Robert Moyer and top management—an internal email chain revealed local shop management and corporate leadership actively placing profit over safety, contradicting logs and technical facts to deny warranty coverage. Confronted with dealer documentation and caught in their deceptive paper trail, the company fully refunded all tire replacement and balancing costs. Internal casing deformation is a critical safety hazard; belt/casing failure at highway speeds creates extreme risk of sudden tread separation or blowout. Dealership diagnostic documentation and the deceitful Executive email chain are available upon request. I also have video of shaking while on the freeway with my infant child in the car moments after Costco management assured me we were safe.Read more

The power door lock actuators on both front doors of my 2021 Toyota 4Runner have failed. The problem developed progressively. The front door locks initially began working intermittently and became less reliable over time. Eventually, both front door lock actuators stopped operating. They have now been inoperative for more than six months. The front doors will not reliably lock or unlock using the
... vehicle's power locking system or key fob, while the rear power door locks continue to operate normally. I discussed the problem with a Toyota dealership and was told by dealership personnel that they have seen this door lock actuator failure happen countless times. Despite the apparent frequency of the problem, I am not aware of a recall covering my vehicle. I am concerned about the safety implications of multiple door lock actuators failing prematurely. The failure prevents the vehicle's power locking system from reliably securing or unlocking the front doors and could cause difficulty quickly unlocking a front door for a passenger or occupant in an emergency. There were no warning lights or dashboard messages before the failures. The primary warning was the progressively intermittent operation of each front door lock before it stopped functioning entirely. Both front doors experienced the same progressive malfunction. I am reporting this because the failure has affected multiple actuators on the same vehicle, has persisted for more than six months, and a Toyota dealership indicated that it has encountered this problem many times.Read more

on 8/13/2026, I was driving alone on West I-80 right before Park City, Ut; I heard a loud pop and my panoramic sunroof exploded which was really scary. I was not using my sunroof at all, so the cover protected everything on the inside. At first I thought it was a flat tire, but no warning messages came onto the control panel. There were not immediate safety issues, so I was able to get to a Toyot
... a Dealership to have it repaired. I did not hear any gravel or road debris flip up onto my sunroof, nor did I hear any under my tires when driving. My vehicle was inspected by a service technician at the Toyota Dealership and he just said it was probably caused by an outside influence.Read more

I purchased a 2013 Toyota Prius from a reputable dealership in Omaha (O'Daniel Honda). 5 days after purchase the ABS, BRAKE, and Traction Control lights came on in the evening. When I took it to the dealership the next day they had cycled off and the dealership couldn't find anything wrong. A few days later it happened again so I got into the dealer right away and they said Toyota had issued a ser
... vice bulletin C1391 in 2019, and that I would have to replace the brake booster, brake cylinder, and brake pump assembly. I'm still fighting with the dealership to make this right, because they should have caught this during their inspection before putting the car for sale on their lot. The indicator lights keep cycling on and off. Something that effects the braking system should be a recall and not a service bulletin.Read more

To Whom It May Concern, I am writing to formally complain about the way Toyota has handled the problems with my 2010 Toyota Prius and my repeated requests for assistance. I have been a loyal Toyota customer and have purchased two new Toyota vehicles because I trusted Toyota's quality and expected good customer service. Unfortunately, after years of contacting Toyota, I have repeatedly been given
... the runaround without receiving a meaningful resolution. I am now facing a serious and expensive brake system problem. The vehicle requires replacement of the brake booster with master cylinder and the brake booster vacuum pump, with an estimated repair cost of approximately $4,000. This is a major safety-related repair, and I believe Toyota should properly investigate the issue and consider warranty coverage or financial assistance. I am also experiencing a serious problem with the paint, which is melting/deteriorating. I have contacted Toyota about these issues before, but the company has not provided the assistance I expected. It is extremely disappointing that after purchasing two new Toyota vehicles, this is the type of customer service I have received. I should not have to repeatedly contact Toyota or file complaints before my concerns are taken seriously. I am requesting that Toyota review my vehicle's history, my previous complaints, the brake system failure, and the paint problem and provide a fair resolution, including consideration of reimbursement or assistance with the approximately $4,000 brake repair. I hope Toyota will take this matter seriously and respond in writing. If Toyota is unwilling to resolve these issues, I will consider escalating my complaint to the appropriate consumer-protection and regulatory agencies.Read more

Incident date: Jul 4, 2026
The component that malfunctioned is the vehicle’s automatic transmission. The transmission developed a progressively worsening humming/whining noise during acceleration. The transmission is no longer available for inspection because the vehicle has been taken to an independent transmission repair shop for diagnosis and repair. The problem creates a safety concern because the transmission develo
... ped significant internal wear or damage and could potentially worsen or fail while the vehicle is being driven. A transmission failure could result in loss of power or unexpected changes in vehicle operation, increasing the risk of an accident, particularly while accelerating or merging into traffic. The problem was reproduced and confirmed by a Toyota dealership. The dealership diagnosed the noise as coming from the transmission and determined that the transmission requires replacement. The dealership recommended replacing the transmission rather than repairing the specific internal component causing the noise. The vehicle was inspected by the Toyota dealership. It is now at an independent transmission repair shop for repair. No police or insurance inspection was involved. There were no warning lights or warning messages on the dashboard before the problem. The first symptom was an unusual whining noise from the transmission area. The noise later changed into a more noticeable humming sound that increases with acceleration and vehicle speed. The vehicle continued to operate, but the abnormal transmission noise persisted and progressively became more concerning.Read more

I own a 2022 Toyota Sienna with approximately 67,680 miles. The vehicle began displaying warnings for **Blind Spot Monitor Malfunction, Rear Cross Traffic Alert Malfunction, and Parking Support Brake Unavailable**. A Toyota dealer diagnosed the problem and found significant corrosion at **both rear blind spot monitor connections**. The wiring harness connector pins had corroded/broken off inside
... the blind spot monitor sensors. The dealer recommends replacing both blind spot monitors and the rear bumper wiring harness and recalibrating the system. The estimated repair cost is **$3,945.84**. I am concerned that both sides of this safety-related system experienced severe corrosion on a vehicle that is less than five years old. These components are not scheduled maintenance or wear items. I have also found reports of other 2021–2022 Toyota Sienna owners experiencing blind spot monitoring failures involving corrosion of the rear sensor/connectors, including another 2022 Sienna at approximately 65,000 miles. Toyota's Brand Engagement Center has documented my complaint but declined to review the repair for goodwill assistance because the vehicle is outside the basic warranty and has not been serviced exclusively at Toyota dealerships. I am filing this complaint because the corrosion simultaneously disables multiple driver-assistance/safety functions and appears unusually premature. I believe NHTSA should investigate whether corrosion or inadequate protection of the rear blind spot monitor connections is affecting other 2021–2024 Toyota Siennas.Read more

A Toyota dealer diagnosed the problem and found significant corrosion at **both rear blind spot monitor connections**. The wiring harness connector pins had corroded/broken off inside
... the blind spot monitor sensors. The dealer recommends replacing both blind spot monitors and the rear bumper wiring harness and recalibrating the system. The estimated repair cost is **$3,945.84**. I am concerned that both sides of this safety-related system experienced severe corrosion on a vehicle that is less than five years old. These components are not scheduled maintenance or wear items. I have also found reports of other 2021–2022 Toyota Sienna owners experiencing blind spot monitoring failures involving corrosion of the rear sensor/connectors, including another 2022 Sienna at approximately 65,000 miles. Toyota's Brand Engagement Center has documented my complaint but declined to review the repair for goodwill assistance because the vehicle is outside the basic warranty and has not been serviced exclusively at Toyota dealerships. I am filing this complaint because the corrosion simultaneously disables multiple driver-assistance/safety functions and appears unusually premature. I believe NHTSA should investigate whether corrosion or inadequate protection of the rear blind spot monitor connections is affecting other 2021–2024 Toyota Siennas.Read more
