One problem related to cruise control has been reported for the 2018 Lexus ES350. The most recently reported issues are listed below.
Cruise control with distance following. This system when active and by design stops slowing the vehicle at an estimated 25 miles an hour. The operator is expecting the vehicle to come to a complete stop and it does not. This is a very serious safety issue and needs to be addressed immediately before rear end collisions become prominent regardless if documented in manuals. Since there are two types of this system the owner may not know with which one they have. So if you're coming up on stopped traffic and relying on the car to stop itself from say 65 70 miles an hour, the car slows to 25 mph or so and suddenly and unexpectedly brakes release you're on your own with only 50 feet or so to bring the car to a complete panic stop. Incredibally dangerous. It should bring the car to a complete stop if necessary. Dates of occurance are various.
