Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

This complaint is submitted to supplement and clarify a prior NHTSA submission regarding Safety Recall 23TA15 for VIN [XXX] . The prior submission was brief and did not fully capture the timeline and circumstances described below. I purchased a 2021 Toyota Sienna (VIN [XXX] ) from Avondale Toyota on [XXX]. At the time of purchase, I was not informed of any active or pending safety recall affecting the vehicle. After returning from Arizona to San Diego with my family, I attempted to list the vehicle on a rental platform on December 26, 2026. At that time, the platform flagged the VIN as having an active safety recall (Safety Recall 23TA15) and prevented the listing. This was the first time I became aware that the vehicle was subject to a safety recall. Despite multiple attempts to obtain clarification from Toyota Brand Engagement regarding the VIN-specific recall activation date, Toyota declined or failed to provide written confirmation. Whether the recall was active prior to the sale or applied shortly thereafter, the vehicle was placed into use without proper disclosure, warning, remedy, or guidance. As a result, my family and I unknowingly operated the vehicle, including interstate travel from Arizona to San Diego, without awareness of a potential safety risk. Had appropriate disclosure or timely notification been provided, I would not have used the vehicle or exposed my family to potential harm. In addition, the recall rendered the vehicle unavailable for its intended business use, resulting in loss of use and financial impact while the remedy was unavailable. I am submitting this supplemental complaint to ensure the full timeline, safety exposure, and lack of disclosure related to Safety Recall 23TA15 are accurately documented.

I was driving my Toyota Sienna on a busy 6 lane highway in the second to the left lane, on a bridge. Suddenly without any warning AT ALL, my vehicle lost all power and came to an abrupt halt in the middle of high speed traffic. My wife and children were all in the car and we were in imminent danger of getting hit by another vehicle. It took the police approximately 10 minutes to arrive during which we were in life threatening danger. After the vehicle stopped a message on the dashboard read Hybrid System Failure. The police tried to push our vehicle to a safe spot but the wheels wouldn't turn and the car had to be towed. Upon inspection by the mechanic it appears that there is a broken shaft in the transmission that may have caused this problem. I want to emphasize that there was NO WARNING at all and we did not have a chance to move to safety.

I turned on my minivan to drive my kids to school when I heard a sudden loud metal shredding/knocking and shut my van off. All maintenance was performed regularly on the van and no lights were on. I have a hole in my engine block now caused by a thrown rod, and no mechanic can explain why this happened. Oil was in good condition, and nothing indicated this should have happened.

I purchased a 2021 Toyota Sienna from United Access Mobility in Sacramento. The vehicle was sold and delivered with multiple serious pre-existing safety defects. The exhaust system was unsafe. The catalytic converter had been stolen prior to sale and replaced with a non-OEM catalytic converter that was improperly welded and mounted too low. This caused exhaust leaks, loud exhaust noise, poor acceleration, and safety concerns including potential exhaust exposure. Multiple professional repair facilities confirmed the exhaust system defect. The electrical system was defective. The vehicle was sold with the wrong size battery that was not properly secured. This caused electrical instability, warning lights, and vehicle failure. The battery was not adequately supporting the vehicle’s electrical system. The airbag and restraint system showed warnings caused by third-party wiring, indicating potential airbag or seatbelt malfunction. The fuel system was defective. The gas cap was broken and required tools to refuel the vehicle. Structural and body components were unsafe. A bumper bracket was loose and flapped while driving, and the passenger seat was unstable. Accessibility systems were also defective, including lift and door malfunctions affecting safe operation. United Access was notified immediately but did not correct these safety defects. Instead, they attempted to have the vehicle repaired using an extended warranty for pre-existing conditions. The vehicle was not safe to operate at the time of sale.

The driver’s side door mirror shakes when going down the road. The image in the mirror becomes shaky. The passenger side is fine, this is only on the driver side. I have brought this into the dealer, but they said it is normal. In 30+ years of driving cars, I have never had a car mirror do this.

STRUCTURE:BODY

Acid rain results from rainwater or other airborne moisture that become acidic due to industrial chemical impurities in the atmosphere. If these acidic compounds settle on an exposed vehicle, especially the horizontal areas such as the hood, roof, and decklid, significant damage to the painted surfaces can occur. Acid rain damage can typically be identified on vehicles by the presence of stains on the paint surface that resemble hard water spots. Unlike water spots however, acid rain damage cannot be removed by regular washing procedures. Also, because acid rain can etch and soften the paint, normal buffing or polishing repair procedures should not be attempted. This can cause further damage and result in visible depressions in the paint surface. The following are the three major categories of acid rain damage: •Minor damage: requires only buffing to repair. •Moderate damage: usually requires neutralizing, color sanding, and buffing. •Severe damage: extending beyond 1/2 mil of clearcoat on a pearl, metallic, or solid color, requires neutralization, sanding, and repainting. In cases where acid rain damage is minor, neutralization and buffing with a liquid-type paint finessing product may provide an adequate repair. Only specially formulated products outlined in this bulletin should be used for that purpose. Unfortunately, other than minor damage, there is no simple method of determining the actual extent (depth) of acid penetration other than color sanding a representative affected area until there is no visible etching or depressions, followed by measuring the amount of paint removed with either a magnetic or digital-type film thickness gauge. The procedures in this bulletin are intended for use by qualified body/paint technicians and should not be attempted by inexperienced personnel. It is the dealer’s responsibility to protect and maintain the quality of the vehicle’s paint finish after receipt at the dealership prior to the first sale. Perform frequent vehicle washing, as often as daily, during high heat and humidity periods to minimize the potential for paint damage due to acid rain exposure. This is especially important in geographical areas known for high frequency and concentration of acid rain and industrial fallout.

STRUCTURE:BODY

To prevent brake rotor rust from forming during transportation and storage, wheel film will be used instead of a cardboard type of anti-rust cover. The purpose of the wheel film is to shield the disc brake rotor from weather elements and initial rust before the vehicle is delivered to the customer. Consequently, the film should remain on the wheel for as long as possible.

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
