Service bulletin 21TC03_DL_Toyota

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.

NHTSA's summary

DL: The subject vehicles are equipped with a low-pressure fuel pump which may stop operating. If this were to occur, warning lights and messages may be displayed on the instrument panel, and the engine may run rough. This will lead to the vehicle entering a failsafe driving mode in which the vehicle can still be driven for certain distances.

20TE04_Dealer Pa	2021-09-13. Service bulletin. 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.
