2022 Toyota Highlander Cruise Control Problems

Your Highlander Hybrid's braking system sometimes lurches or surges forward instead of braking smoothly, especially at low speeds or downhill, creating longer stopping distances and unpredictable braking behavior. This problem happens intermittently without warning lights and appears to worsen over time, particularly when the hybrid battery is fully charged. A Toyota dealership performed a software update (TSB) to address this issue, but the problem persists even after the repair. Fixing this will likely require further software diagnostics or hardware inspection of the regenerative and friction braking system components.

Your 2022 Highlander unexpectedly accelerated on its own while you were stopped at a traffic light with your foot on the brake pedal. This has happened multiple times, and it also lurched forward once while parked. You've reported the issue to your Toyota dealer and the manufacturer, but the cause hasn't been identified yet.

Your vehicle is suddenly skidding sideways and veering to the right while driving at constant speed on snowy roads, even at speeds as low as 15 mph, with no warning lights or traction control alerts. This happens randomly multiple times over several miles, causing you to nearly hit guardrails and parked cars, and the dealer found no diagnostic codes or active recalls despite a previous VSC recall repair. The problem suggests a sensor or control module may not be calibrated correctly, affecting your braking and acceleration stability.

Your vehicle unexpectedly surged backward while reversing out of a driveway, even though the brake pedal was pressed. When shifted into drive, the vehicle accelerated forward uncontrollably until hitting a tree. The airbags did not deploy during the incident. This suggests a potential issue with the vehicle's speed control or brake system that needs immediate investigation.

Your vehicle's wire harness was damaged by rodents in the engine compartment, and Toyota says it needs to be replaced. You're concerned that if animals can access and damage wiring under the hood, they could potentially enter the cabin while you're driving at highway speeds, creating a safety hazard. The fix will involve replacing the damaged wire harness and potentially adding protective measures to prevent future animal intrusion.
