Greetings, we have a 2008 rav4 which has twice exhibited uncontrolled engine acceleration. My wife has contacted Toyota to no avail. Toyota has recalled other models but not the rav4. They have not heard our complaints as a mortal safety concern. It is as if we are trying to con the company. As a lifelong safety professional, this is very disturbing. Please advise as to our possible actions.…

What stands out
No new NHTSA electrical complaint has been filed on this vehicle in over 15 years — the issue may be aging out of the active population.
The failure pattern owners describe
Owners of 2008 RAV4s describe electrical failures that dealers consistently fail to identify or repair. Unintended acceleration occurred at traffic lights and highway speeds with no diagnostic codes found; one owner's RPM approached redline despite foot on brake. Two separate power window fires burned while driving or parked, with flames visible at switch locations and wiring; both required owner intervention to extinguish.
Multiple owners report all dashboard warning lights illuminating repeatedly after rain exposure, with cruise control failing during these episodes. One mechanic found water pooled inside wiring harness connectors with no identifiable entry point; the problem recurred after repair. Battery failures dominate the complaints—some premature at 18,000 miles, others leaking acid three times requiring replacement and leaving corrosion damage across engine components.
Engine stalls without warning while driving; alternators smoke at low speeds without warning lights activating. One vehicle caught fire while parked, with the heaviest damage at the battery location. A dealer-identified soy-based wiring insulation attracts rodent damage. Spiral cable failures affect airbag deployment in collisions. The consistent thread: owners report real, sometimes dangerous symptoms—fires, stalls, acceleration surges—yet dealership diagnostics repeatedly show nothing wrong, making them impossible to address under warranty.

Failure modes owners describe
Unintended acceleration / engine surging
Engine revs unexpectedly or surges forward without driver input, occurring at highway speeds or above 25 mph. In one case, accelerator revved to near-redline while vehicle was stopped at a traffic light despite foot on brake; in another, surging occurred repeatedly at highway speeds. Dealers unable to reproduce or find diagnostic codes.
When: At highway speeds or light acceleration above 25 mph; one incident at traffic light after 30 seconds at stop
Symptoms owners cite: Sudden engine rev and forward surge while foot on brake; RPM approaching redline; All dashboard warning lights illuminating; Unintended surging at highway speeds; Cruise control failure during surging episodes
Repairs/costs cited: Dealership diagnostics reported 'all normal'; one dealership blamed floor mats (owner disputed). No successful repair documented.
Recalls/TSBs owners mention: Dealership testing inconclusive; no TSB or recall issued for unintended acceleration on this model year
Power window circuit fire
Electrical fire igniting at power window master switch or in door wiring while vehicle operating. Two separate incidents: one fire at driver-door power window switches burning with visible flame; another fire in driver-side door wiring. Both fires suppressed by owner action; windows rendered inoperable or partially disabled post-incident.
When: While driving at highway speed (65 mph) and at low speed (25 mph, parked)
Symptoms owners cite: Strong burning odor; Heavy smoke from power window switches; Visible flame at switch location; Fire in driver-side door wiring; Windows becoming inoperable post-fire
Repairs/costs cited: No factory repair documented. Owner extinguished fires with coffee and water. Power windows damaged as consequence; only driver window functional in one case.
Multiple warning lights illumination after rain exposure
All dashboard warning lights illuminate after vehicle driven in light or heavy rain, occurring repeatedly over time. Lights illuminate even after restart or parking and restart. Cruise control fails when lights activate. Vehicle feels unstable ('rolling on marbles'). Diagnostics reveal multiple codes that clear when reset, but lights and cruise failure return with next rain exposure.
When: After light rain, moderate rain, heavy rain; one incident 60 mph highway
Symptoms owners cite: All dashboard warning lights illuminating; Cruise control failure at set speed; Vehicle feels like rolling on marbles (traction issue sensation); Multiple diagnostic codes appearing; Anti-skid control activating randomly when stopped
