Service bulletins for the 2023 Toyota Sequoia
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.

| T-SB-0026-24 Rev1 | 2024-09-07. Service bulletin. ELECTRICAL SYSTEM. Some 2022 – 2024 model year Tundra and Tundra Hybrid, and 2023 – 2024 model year Sequoia Hybrid vehicles, equipped with a JBL® premium sound system, may exhibit a rattle or buzz noise when listening to music coming from the subwoofer located in the rear left luggage area of the vehicle. This can be caused by exposure to certain operating environments with high humidity levels. To improve the subwoofer's performance in humid environments, Toyota has revised the speaker cone material and shape. The condition can be resolved by replacing the subwoofer assembly with box. |

| T-SB-0055-24 Rev1 | 2024-08-08. Service bulletin. STRUCTURE:BODY. Some 2005 – 2024 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. This Service Bulletin is to provide a general overview and direction for the odor remediation process. |
| T-SB-0039-24 Rev1 | 2024-08-08. Service bulletin. 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 (see Figure 1), 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 Rev1 | 2024-08-08. Service bulletin. 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. |
| T-SB-0035-24 Rev1 | 2024-08-08. Service bulletin. 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. |
| T-SB-0043-24 Rev1 | 2024-08-08. Service bulletin. SERVICE BRAKES. Some 2023 – 2024 model year Sequoia Hybrid, and 2022 – 2024 model year Tundra and Tundra Hybrid vehicles may exhibit a condition where the front brakes produce a squealing noise when driving forward or in reverse. |
| T-SB-0026-24 Rev1 | 2024-08-08. Service bulletin. ELECTRICAL SYSTEM. Some 2022 – 2024 model year Tundra and Tundra Hybrid, and 2023 – 2024 model year Sequoia Hybrid vehicles, equipped with a JBL® premium sound system, may exhibit a rattle or buzz noise when listening to music coming from the subwoofer located in the rear left luggage area of the vehicle.

| T-SB-0030-23 Rev2 | 2024-07-23. Service bulletin. STRUCTURE:BODY. Some 2023 – 2024 model year Sequoia Hybrid and 2022 – 2024 model year Tundra and Tundra Hybrid vehicles may exhibit lack of power during acceleration and/or a MIL ON condition with one or more of the following Diagnostic Trouble Codes (DTCs): •P017400 – System Too Lean Bank 2 •P117B00 – Fuel Performance/Direct Injector •P043000 – Catalyst System Efficiency Below Threshold Bank 2 |
| T-SB-0061-23 Rev1 | 2024-07-23. Service bulletin. 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. |
| T-SB-0062-23 Rev1 | 2024-07-23. Service bulletin. 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. |
| T-SB-0055-24 | 2024-07-23. Service bulletin. STRUCTURE:BODY. Some 2005 – 2024 Toyota vehicles that have undergone water intrusion may exhibit a condition in which a musty odor is present.
