Service bulletins for the 2020 Toyota RAV4
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.

| 20TE05_Dealer Pa | 2021-09-13. Service bulletin. FUEL SYSTEM, GASOLINE; ELECTRICAL SYSTEM:INSTRUMENT PANEL:FUEL GAUGE. DP: Toyota has received customer reports of certain 2020 model year RAV4 HV vehicle fuel gauges displaying less than full and/or total fuel dispensed is less than expected, when the fuel nozzle automatically clicks off. Some customer reports have also noted the ?Distance to Empty? shown on the multi-information display is less than expected. Based on our investigation, Toyota believes these conditions to be primarily related to the fuel sender gauge design. These conditions can cause the fuel level to be read incorrectly and may cause the low fuel light to illuminate with more fuel in the tank than usual. Although the fuel sender gauge unit is covered by Toyota?s New Vehicle Limited Warranty for normal Basic Warranty coverage period, 3 years or 36,000 miles (whichever comes first), we at Toyota care about the customers? ownership experience. Toyota is providing coverage for repairs related to refueling performance concerns. The following information is provided to inform you and your staff of the program notification schedule and your degree of involvement. |
| 20TE04_Dealer Pa | 2021-09-13. Service bulletin. FUEL SYSTEM, GASOLINE; ELECTRICAL SYSTEM:INSTRUMENT PANEL:FUEL GAUGE. DP: Toyota has received customer reports of certain 2019-2021 model year RAV4 HV vehicle fuel gauges displaying less than full and/or total fuel dispensed is less than expected, when the fuel nozzle automatically clicks off. Some customer reports have also noted the ?Distance to Empty? shown on the multi-information display is less than expected. Based on our investigation, Toyota believes these conditions to be primarily related to a variation of fuel tank shape and the potential for the fuel sender gauge to become inclined. These conditions can cause the fuel level to be read incorrectly and may cause the low fuel light to illuminate with more fuel in the tank than usual. Although the fuel tank and fuel sender gauge unit are covered by Toyota?s New Vehicle Limited Warranty for normal Basic Warranty coverage period, 3 years or 36,000 miles (whichever comes first), we at Toyota care about the customers? ownership experience. Toyota is providing coverage for repairs related to refueling performance concerns. Note: Fuel tanks are covered under the normal California Emissions Control Warranty period, 7 years or 70,000 miles (whichever comes first), for the following states: Connecticut, Delaware, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, and Washington. |

| T-SB-0047-19 Rev | 2020-09-14. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM(GLOBAL POSITIONING SYSTEM). TSB: Some 2018 ? 2020 model year Toyota vehicles equipped with a Premium Audio with Dynamic Navigation System require a Special Service Tool (SST) USB flash drive to update the map, points of interest, and system software. The SST is used with applicable vehicles to deliver the update; however, the process for generating license keys differs from previous generations. Before attempting to perform a map update, the head unit?s expiration date must be checked. If the expiration date is still valid, a license key may be generated without the use of an activation card number. Updating the maps without the use of an activation card number is considered an Embedded Navigation Update (refer to pg. 10) and performing this process does not extend the duration of telematic map services. If the head unit?s expiration date is expired, or is expiring within the next 90 days, it should be recommended to the customer to purchase an activation number. Utilizing an activation number will initiate a Dynamic Navigation Update (refer to pg. 4). This Dynamic Navigation Update will perform the Embedded Navigation Update and provide telematic map services for a period of two years from the day that the Dynamic Navigation Update is performed. Activation card numbers are provided in an activation card number pamphlet available through the normal parts ordering system. |
