What stands out
No new NHTSA engine complaint has been filed on this vehicle in over 4 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Owners of the 2018 RAV4 describe a range of critical engine and electrical failures starting as early as 6,900 miles through 107,000 miles. Battery failures are recurring: one owner went through three replacements before 55,000 miles and faced premature alternator failure, typically seen on much higher-mileage vehicles.
Engine fires are the most severe complaints. Three owners reported vehicles catching fire at 48,000, 68,000, and 107,000 miles, with smoke visible from under the hood before flames. Two fires broke out while driving; one occurred in a garage. Fire departments responded in multiple cases, and vehicles were totaled.
Unintended acceleration emerges in at least two incidents where the engine revved unexpectedly while the vehicle was stopped, continuing despite brake pressure and resulting in a rear-end collision.
Loss of power while driving—complete shutdowns on the highway—puts owners and other drivers at risk. One stall event at 35 mph preceded an engine fire.
Additional issues include transmission malfunctions showing AWD and TRAC warnings appearing within three months of ownership, excessive heat and odor radiating from the engine compartment, rapid fuel depletion with emission warnings, and crankshaft sprocket failure breaking the timing chain guide around 60,000 miles.
