FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

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.

LANE DEPARTURE: WARNING

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.

England, AR

LANE DEPARTURE: ASSIST

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.

St George, SC Crash

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

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.

Burnsville, MN

FORWARD COLLISION AVOIDANCE: WARNINGS

Problems: 1) Check Engine Light lit up. 2) "Hybrid System Malfunction" warning on heads-up display. 3) "Pre-Collision System Failure" warning on Heads-Up Display. 4) Gasoline engine stalls after an intentional deceleration and is unable to come back up to speed. First Event: On July 4th, my wife and I were driving on an interstate highway. We entered an exit ramp interchange to merge onto another highway and when trying to accelerate the car suddenly became sluggish, and gave messages for problems 1), 2), and 4) stated above. Problem 3) did not occur during this event. Messages stated to pull over in a safe location. We parked on the shoulder and immediately shut the car off, waited 5 minutes and then started the car again. We were able to drive to the next off-ramp to a city street (about 100 yards) before the engine started becoming sluggish again and lurching, error messages remained throughout the event. OBD codes stated simply "faulty engine" on a car with 16,000 miles. Dealership was unable to find a cause, but did find a code for ignition failure. They checked some things but did not do any repairs, and were unable to replicate the issue as it seemed to have cleared. Diagnosis was "vapor-lock" and no explanation for why. Second Event: On August 6th, my wife was driving the vehicle to visit family, when pulling onto an exit ramp, was unable to accelerate again afterwards. All the same warnings popped up, but this time also had problem 3). Engine stalled when warnings appeared and did the same sluggish lurching. After pulling off in a safe area, Shut the car off and tried to restart 4 times, warning did not clear. Gasoline Engine does not operate when pedal is pressed. Shut the car down for 2 hours and tried to restart afterwards, warnings still present, engine now runs when pedal is pressed, but stalls when idle. Shutdown for another hour while waiting for a tow, warnings still present, still stalls when idle. Waiting on callback from dealership.

Riesel, TX Crash

FORWARD COLLISION AVOIDANCE: WARNINGS

While driving onto an exit ramp I applied my brakes to my 2019 Toyota Highlander but the engine just roared up, took my foot off the brake and applied both feet to the brakes and the engine roared up again, I then came up right behind a car at the intersection and the front end collision did not stop me so I survived to the left lane but then I was headed into the highway and was T-boned by another Toyota Highlander and came to a stop on the right side of the highway. All the air bags deployed in the other SUV but none deployed in mine. The fireman had to use the jaws of life to get me out of the SUV. My wife and I were very shook up but had no serious injuries. But my brakes, the front-end collision, and the airbags all failed in the Toyota. My Highlander was totaled by my insurance company but they will not investigate the failures.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

A MONTH AGO, WE WERE DRIVING ON THE HIGHWAY THROUGH SNOW SHOWERS UP TO NH TO GO SKIING, WITH OUR NIFTY ADAPTIVE CRUISE CONTROL ON, WHEN I REALIZED THAT WE WERE ACCELERATING INTO THE CAR IN FRONT OF US. I ASSUMED THAT THE FRONT SENSOR WAS COVERED IN SLUSH, TOOK OFF THE CRUISE CONTROL AND DROVE MANUALLY. ONLY ABOUT 5 MINUTES LATER DID THE DASHBOARD ALERT NOTIFY ME THAT THE FRONT SENSOR WASN'T WORKING. BROUGHT IT INTO THE DEALER. THEY COULDN'T FIND ANYTHING WRONG. HERE'S THE PROBLEM: THE CAR SAYS "TRUST ME. IF YOU USE MY COOL SAFETY SYSTEMS, I'LL KEEP YOU FROM HITTING THE CAR IN FRONT OF YOU...AND SHOULD SOMETHING DISABLE THE SENSOR THAT CARRIES OUT THIS FUNCTION, I'LL LET YOU KNOW, SO THAT YOU WON'T DEPEND ON ME." BUT THAT'S NOT TRUE. AND, A DRIVER WHO ASSUMED THAT THE CAR WAS KEEPING ITS PROMISE, AS IT DOES MOST ALL THE TIME--MIGHT NOT HAVE REALIZED THAT IT WASN'T UNTIL THEY HIT THE CAR IN FRONT OF THEM.
