Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical 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.

Any previous printed versions of this bulletin should be discarded. In the event that a Toyota vehicle becomes submerged in water, many components may be physically damaged. Electrical and electronic components, including wiring harnesses, are particularly susceptible to corrosion and subsequent malfunction. Although any flooding can be damaging, salt water flooding elevates the potential for abnormal conditions and may increase risks due to its highly corrosive and conductive nature. Salt residue also continues to corrode and remain conductive even after a vehicle dries.

The failure pattern owners describe
This 2010 RAV4 electrical cluster shows three persistent problem patterns. First, water exposure—rain or deep puddles—triggers check engine, slip indicator, and 4WD lights simultaneously; dealers tell owners either there's no fix or Toyota is investigating. Second, alternator failures occur around 130k–160k miles, sometimes causing steering lockup and power loss mid-drive; both owners faced out-of-warranty repair costs of several hundred dollars. Third, intermittent starting failures persist even after replacing battery, starter, and starter safety switch, pointing to deeper electrical gremlins.
Scattered one-off issues include engine surge at low speed (blamed on ECU chip, not pedal), power window switches sticking or failing, AC compressor internal sensor failure, radio display glitches, and one catastrophic vehicle fire at 98.5k miles that fire department couldn't diagnose. One complaint mentions unintended idle revving at a traffic light.
The water-related warning light pattern appears systemic—multiple owners report it, and dealers admit to either no solution or ongoing investigation. Out-of-warranty status is common here; at 130k–160k miles, Toyota won't assist.
