2019 Toyota Highlander

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.

The engine can be turned off while the shift (automatic) lever is not in Park. If the driver does not realize the failure to put the lever in Park, the car can roll freely. My car is available for inspection, but I was given to believe by Toyota service that this is a standard feature on all 2019 Highlanders. Safety is continually at risk because the car can roll and cause injury to an exiting passenger, another car, or a pedestrian. The car has not been inspected for this since Toyota does not believe this is a problem. There is a warning lamp triangle ! but no sound. The message says "Shift to P before exiting vehicle" . While proper parking is my responsibility, I have not seen the in any other type of vehicle in which I have ridden or driven, Honda, GMC, Chevrolet, Dodge Aspen--all owned and driven by me. This is an ongoing "condition", not an "incident".

Poser steering failed momentarily. I was at the drive-thru window of CVS and was afraid my mirror would hit the pole when I pulled forward. I tried to turn while backing up slowly from a full stop. The car momentarily resisted my attempt to turn the wheel. There was no safety risk at the time. I have not had the problem investigated. The problem quickly corrected (within 2 seconds(?), o I did not notice or look for any warning lamp or message. I have read of steering failure on highways in the 2019 Highlander and am concerned that this is a harbinger.

Took the vehicle twice to Toyota to check on console vibration originating from possible drivetrain (normally in cold weather). This was done under extended warranty. Also had transmission fluid replaced. Service department noticed fluid low even though there was no transmission leak. Service department couldn't duplicate issue but failed to attempt start of vehicle in early mornings as requested. About 10K miles after last attempt to get issue fixed, the transmission failed with no caution, no warning and no error codes. Symptoms included little to zero acceleration from a dead stop and inability to accelerate to higher speeds when necessary (main safety issue). Eventually, vehicle was not able to accelerate. This vehicle does have the 8-speed AT Transmission that lawsuits are being filed against.

The SOS system is malfunctioning and causing an earsplitting screech on the 2019 Toyota Highlander Platinum. This occurs around every third time when the car starts and is damaging my hearing and my kids' hearing. This is well documented on the Toyota Nation forum and Reddit. Toyotanation: [XXX] : [XXX] Here is a video of it occurring on someone else's vehicle: [XXX] "Toyota service technician at our local dealership heard the loud sound when servicing the vehicle. They talked to Toyota and they said: "TAS agent stated there has been multiple cases of the DCM causing this concern, and the repair is to replace the DCM or disable it." Toyota is charging consumers for this factory defect. Please make Toyota address this problem. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

We believe the problem is in the SOS system. This is an intermittent problem that occurs about every 5 to 15 starts. At start-up, an ear piercing scream/screech comes from somewhere in the front speakers and lasts about 2 to 5 seconds. At times the scream is so loud that it leaves a ringing in your ears. We are very concerned about our grandkids riding in this vehicle. This problem needs to be addressed, it’s not going away and it’s making it different to drive.

When I start my 2019 Highlander there is a loud screech that startles you and makes you jump out of your seat. It’s a very loud feedback noise through the speakers, and the red and green lights near the SOS button flash multiple times. This happens very often but intermittently, and when it doesn't happen the SOS button only flashes red/green once. This happened after the SOS trial service had expired. I called the SOS service and they told us to talk to the dealership. There needs to be a recall of the SOS module or whatever is causing this.
