Service bulletin T-TT-0613-20
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

A recall listed here may apply to some of the same vehicles. Only the manufacturer can say whether it applies to one vehicle.
| T-SB-0040-24 Rev1 | 2026-07-08. Service bulletin. Some 2020 – 2026 model year Highlander and Highlander Hybrid vehicles may exhibit a water leak from the roof rack attachment clips. This may be caused by the sealant in the roof channel obstructing the proper seating position for the clip gasket. |
|---|---|
| T-SB-0097-23 Rev1 | 2026-05-08. Service bulletin. Some 2018 – 2024 model year Camry and 2018 – 2026 model year Camry Hybrid vehicles may exhibit the weatherstrip on the panoramic roof center glass peeling on the edges of the glass. |
| T-TT-0795-25 | 2026-01-09. Service bulletin. Some customers may experience a condition in which the 2021-2025 Sienna HV 2nd row FRAME SUB-ASSY, No.1 does not function even when the stow lever is pulled. Because the cable has come off from the bracket that holds it inside. |
| T-SB-0086-25 | 2025-12-05. Service bulletin. Some 2020 – 2023 model year Highlander and Highlander Hybrid vehicles may exhibit a condition in which the Power Back Door (PBD) will not open or close and/or stops moving while opening or closing. A modified PBD unit assembly is available to address these conditions. |
| T-SB-0082-25 | 2025-12-05. Service bulletin. Some 2021 – 2025 model year Sienna Hybrid vehicles may exhibit a sloshing or splashing noise from inside one or more door panels when driving, opening and/or closing a door, and/or braking. This condition may be caused by cavity wax, debris, or other materials that may block door drain holes and restrict water from draining properly. |
| T-SB-0001-25 | 2025-02-12. Service bulletin. Some 2021 – 2024 model year Sienna Hybrid vehicles may exhibit a condition in which the front passenger carpet is untucked and torn at the center console, as shown in Figure 1. To address this concern, a carpet patch has been developed to reduce the likelihood of this condition from occurring. |
| T-SB-0010-24 Rev1 | 2025-01-09. Service bulletin. Some 2021 – 2022 model year Avalon, 2018 – 2024 Camry, 2019 – 2025 model year Corolla, 2022 – 2025 model year Corolla Cross, and 2019 – 2025 model year RAV4 vehicles with A25A-FKS and M20A-FKS engines may have a MIL ON condition with one or more of the following Diagnostic Trouble Codes (DTCs) upon cold soak start up with engine coolant temperatures between 14°F – 41°F: •P030027 – Random/Multiple Cylinder Misfire Detected (Emission) Signal Rate of Change Above Threshold •P030000 – Random/Multiple Cylinder Misfire Detected •P030100 – Cylinder 1 Misfire Detected •P030200 – Cylinder 2 Misfire Detected •P030300 – Cylinder 3 Misfire Detected •P030400 – Cylinder 4 Misfire Detected |
| T-SB-0039-24 Rev2 | 2025-01-09. Service bulletin. 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. |
| T-SB-0038-24 Rev2 | 2025-01-09. Service bulletin. 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. |
| T-SB-0035-24 Rev2 | 2025-01-09. Service bulletin. 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. |
