general problems of the 2015 Toyota Highlander

Upon being reviewed the rear u joint was loose & needed replaced @ 167,361 miles.

On the freeway off ramp, during the slow down- and down shifting-process the vehicle appeared to block the wheels and to skid for a short time. Also, the vibration feature that indicates loss of traction got activated for that time and the “slip indicator” warning light lit up (I do not know for how long). During the incident I felt not in control of the vehicle. Once the incident passed I retained control of the vehicle , yet the automatic transmission started to act very peculiar and frequently failed to downshift in a normal way which could only be achieved by intentionally taking pressure of the gas pedal, and only after the downshift had happened, more power cold be applied. Another brief and less pronounced perceived jolt happened on the short remainder of the drive home. Once parked at home I realized that the car would not engage when the lever was put in “reverse”, but would engage when put in “drive”. I plan to have the vehicle towed to my Toyota service station and have it inspected/fixed.

Tl- the contact owns a 2015 Toyota Highlander. The contact stated while approaching a parking spot, when the vehicle accelerated independently and ran over a parking sign. The contact stated she was depressing on the brake pedal but failed to stop the vehicle. The contact stated no warning light was illuminated. The contact was able to continued drive the vehicle to her destination. No police report was filed. The vehicle was taken to local dealer downeast Toyota (652 wilson st, brewer, me 04412: (866) 620-9023) and were it's still being serviced. The vehicle had not been diagnosed or repaired as of yet. The manufacturer had been informed of the failure. The failure mileage was approximately 72,000. Dp.

In the freeway running 65 mph , car start juggling and vibration , so I slow down to 60 mph and proceed going home , happened last night 9 pm.

When trying to merge with traffic at an onramp, the vehicle will frequently refuse to downshift to match traffic speed when doing 35-50mph. This has resulted in several close calls under these circumstances and I never know when this will happen. This forces a manual downshift that cannot always be in time. This same problem has been reported on numerous forums and some have reported having to "trick" the transmission into downshifting.

When driving my Highlander the following error messages appeared, error keeping the start button pressed will cause an emergency stop. I dismissed this. Then it popped up a message that car cannot drive while brake and accelerator are pressed simultaneously. I lost ability to accelerate so tried to pull of busy road, pressing the brake pedal restored acceleration. Then when I stopped in traffic or at lights the car shut itself down and had to be restarted. These error messages kept coming on while I drove to the dealer. I switched off the car at the shop and it wouldnt repeat the problem, no codes have been recorded by the vehicles computer because the check engine light never came on. Toyota and the dealership want to wait until it happens again. Since it happened before, also while it was driving I am uncomfortable as it is a safety concern. I don't want it to happen on a busy highway. I believe the intelligent power module of the car is shorting out and causing the car to go into failsafe mode and shut down creating hazardous driving conditions.
