I have had the traction control go on while driving on the highway even when I turn it off. Sometimes the VSC and TRAC OFF lights go on while driving. The roads are dry. Whenever I take it in to the mechanic, all the lights are off. They pulled a zero calibration code and recalibrated. It still kept happening. Then I was driving around a curve on highway speeds when the traction control light went on and the van suddenly braked on its own and I almost lost control. The tires are new and the roads were dry.

The head gasket that was repaired failed and the radiator system also failed. Im not sure if these issues are dealer related or manufacture related as i spoke to the previous owner and they stated they had the vehicle serviced at a manufacturer prior to doing a trade in with the dealer

The material used by Toyota to manufacture the dash is breaking down. Toyota is aware of this issue due to cracking and offered a limited extended warranty which I never received any notification (and many others did not per Toyota's chat forum). Cracking I can deal with. But now the material is continuing to break down and a thick sticky liquid is separating and rising to the surface creating a terrible sheen. When exposed to direct sunlight the visibility through the front windshield is dangerously low. The road basically disappears. I brought this to the attention of Toyota Brand Engagement Center on Nov. 10. 2023 (File #231110000552). I requested Toyota do the right thing, update their response policy, and authorize a dash replacement at a local Toyota dealership, but they refused based on the response policy they had established many years ago even after I explained the situation is not just cosmetic any longer. I explained the sudden loss of visibility and how incredibly dangerous and frightening it was, but they still refused to address the issue, so I am forced to bring this to your attention. Based on the Toyota's forum this is a widespread issue through several model years. Based on my experience I am confident there will be many accidents due to this manufacturing defect. Please investigate and request Toyota do the right thing to protect their customers.

The contact owns a 2008 Toyota Sienna. The contact stated while driving 60 MPH, the vehicle unintendedly accelerated at a high rate of speed. There was no warning light illuminated. The contact desperately pressed on the brake pedal, but the vehicle would not slow down. The contact shifted the gear lever into neutral and the vehicle slowed down. The contact was able to pull over on the side of the road and shutoff the vehicle. The vehicle was restarted and operated normally. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was 178,000.

Issues with VSC. The sensor alarm goes off when driving at more than 50 mph and slightly turning the steering wheel. The car brakes itself and this is DANGEROUS. It happens all the time, it has been more than 5-6 years and we are to the point of not using the car on the freeway to prevent a potential fatal accident. I found posts describing the same issue with this model of Toyota. Car should be recalled to get this fixed.

Manufacturer communications
A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.
Some 2005 – 2026 Toyota vehicles that have undergone water intrusion may exhibit a condition in which a musty odor is present. Follow the procedures in this bulletin to remediate the odor and address this condition. The purpose of this Service Bulletin is to provide general guidelines and procedures for odor remediation. This Service Bulletin provides a guide on how to prepare and treat the interior of the vehicle for odor remediation. Refer to the applicable model and model year Repair Manual and the EPA (Environmental Protection Agency) website for the most up-to-date safety and precautionary guidelines.
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
The condition known as acid rain is caused by airborne chemicals or particles in the atmosphere, which mix with rainwater, nighttime dew, or high humidity to form acidic compounds. If these contaminants settle and remain on a painted vehicle surface, especially the horizonal areas of the hood, roof, and decklid, significant damage can occur. This damage is the result of actual etching of the paint and appears as pitting or water spots. As acid rain droplets on the vehicle surface evaporate, the concentration strength of the acid increases, causing deeper and more rapid damage. This evaporation and corrosive action also occur more rapidly on dark colored cars as direct sun heat increases. 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. In areas known for high frequency and/or concentration of acid rain, frequent vehicle washing during high heat or humidity periods will minimize the potential for paint damage caused by acid rain. It is further recommended that either reverse osmosis or deionized water be used to prevent water spotting.

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.
STRUCTURE:BODY
Toyota vehicles are currently protected with RapgardTM protective film designed to protect the horizontal painted surfaces. This material protects from acid rain, environmental fallout, and rail contamination. Follow the Removal Procedure in this bulletin to remove the RapgardTM protective film within 90 days from initial application.
STRUCTURE:BODY
Vehicles may occasionally be subjected to contamination by airborne iron particles shed from railroad tracks, train wheels, exposure to heavy machinery facilities, grinding, welding, etc. This type of contamination can be identified by the presence of small, red or brown particles on the paint surface. These particles are often difficult to see on dark color paints but can be easily felt when brushing a hand across horizontal body surfaces such as the hood, roof, or deck lid. Follow the Repair Procedure in this bulletin to clean vehicles that may have been subjected to contamination by airborne iron particles such as rail dust during rail transportation or extended storage near industrial areas.
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.
