2017 Toyota Sequoia — Known Issues & Recalls

Your vehicle suddenly accelerated while parked with the engine running and three children inside, causing it to crash through trees and fences before stopping in the woods. When you reached the vehicle, you found the gear shift had moved out of Park to a position between Park and Drive, and the engine was still revving at high speed. You also reported two earlier incidents where the vehicle experienced unexplained power loss and surge issues, followed by sudden deceleration and reacceleration on cruise control, which Toyota was unable to diagnose or repair. The repair will likely require a full diagnostic of the transmission shifter mechanism, electronic throttle control system, and cruise control electronics to identify why the vehicle is shifting out of Park and experiencing unintended acceleration.

Your sunroof spontaneously shattered while you were driving. This is a sudden failure with no known cause at the time of the incident. The repair will likely require replacement of the entire sunroof glass panel and associated hardware.

Your fuel pump may fail when driving at high speeds or in cold weather conditions. This can cause your engine to lose power or stall while you're driving. Toyota service identified this as a fuel pump issue that may require replacement of the fuel pump assembly.

Your car shakes when driving at 50 mph and above, and your check engine and 4LO warning lights flash on. A mechanic diagnosed that your fuel pump needs to be replaced. Toyota confirmed your vehicle isn't included in their current recall for this issue. Replacing the fuel pump typically involves accessing the fuel tank and installing a new pump assembly.

Your engine continues running even after you turn off the ignition, with no warning light to alert you. A Toyota dealer suggested a low battery was the cause, but the problem keeps happening even after you've charged the battery. This suggests an underlying electrical issue is preventing the engine from shutting down properly. The fix will likely involve diagnosing the ignition system or engine control module to identify why the shutdown signal isn't working.

Your vehicle lost engine power when you pressed the accelerator pedal. A dealership diagnosed the problem as rodent damage—animals chewed through wires that were coated with peanut oil, preventing the engine from responding to throttle input. The repair would likely involve replacing the damaged wiring harness and possibly adding rodent deterrent measures to prevent future damage.

When driving on the freeway at 65-70 mph, you hear a whistling or metal-on-metal sound coming from the left side of your car, though it's unclear whether it's from the windshield or frame area. You also notice a constant squeaking noise at the right corner where the windshield meets the dashboard. These noises likely involve loose or improperly sealed windshield trim, weatherstripping, or frame components that may need adjustment or replacement.
