I was using the adaptive cruise control on I-68 in Western Maryland. I was in the fast lane (on the far left of three uphill lanes). A dump truck was in the center lane going well below the speed limit. The road curved to the left at the point where I got up to the dump truck. There was no one in front of me in my outside lane. My car sensed the presence and speed of the dump truck and slowed me abruptly. There was considerable risk to me and to the driver of a white pick-up truck that was behind me, and who was also driving at passing speed. We were both going approximately 75 mph when my car slowed--a slowing that does not display brake lights. The cruise control has not been inspected. It is the default setting on ignition. I routinely disable it, opting for regular cruise, each time I use it, but the potential is always there for me and for other owners. If there was any sort of warning (I don't remember) it would have been inadequate to prevent an accident. The alertness of the pick-up truck driver saved us both a collision.

Originally, 2019 Toyota Highlander lost engine power, steering, and braking on U.S. Route 30, a very busy highway. Managed to pull off side of road AND WAITED. AFTER A FEW MOMENTS CAR STARTED AND RAN AS EXPECTED.Took to local dealer who had the car for several days, but couldn't identify the problem. This instance was 2020/2021. Fast forward to this past September 26th. Pulling out of a private parking lot the car stalled exactly as it had previously.This complete failure of engine is going to get me killed. Further I now notice my dash lights are dimming for no reason then coming back to bright. Now I read where other Highlander are doing the exact thing. I have a car, I'm afraid to drive.

The door locks will not unlock or lock. Had to replace two so far and now the other side is doing the same. Pre collision, Lane departure, cruise control and traction have malfunction. Unknown as to why at this moment.

Vehicle constantly drift to the left which make it very unsafe because the driver is in a continuous correction mode to remain in one lane - can inspect anytime, alignment and tire rotation has been complied with at least 8 times within the last 3 months by Toyota Dealer and Firestone conclusion alignment is OK sometimes with minor correction. I'm constantly holding pressure on the steering to the right and left to remain in my lane doesn't matter about the road. The problem is worst on multi - lanes in the same direction with tractor trailers passing due to air current.

While driving threw a construction zone the car upfront of me stopped. Upon applying the brakes nothing happened. There was a tractor trailer beside us and I was at the reR and another car was at the front plenty of time to stop. Brakes didn't activate until right before impact and the nose dove down. ABS never activated and the collision avoidance never activated. I was traveling with my wife and two young kids lucky no one was hurt and I had no avenue of escape due to cement barriers and 18 wheeler.
