2022 Toyota Highlander

While driving at a constant speed of approximately 45 mph the vehicle suddenly skidded sideways and launched to the right, causing us to nearly hit a guardrail. I dropped speed to 30 mph and this continued to occur at random for the next 10 miles until destination was reached. Road conditions were patchy snow up to fully covered in snow. Other vehicles passed at 50+ mph with no issues. No warning lights/messages or traction control light turned on. Today the same issue occurred while driving 15mph that caused the vehicle to almost run into a parked car. This has occurred at random over the past two days. All instances occurred while driving at a constant speed, no brakes were being applied and while driving in a straight line. This isn’t the first time the vehicle has been driven in these road conditions but first time problem has occurred. This is a safety hazard for my wife and child due to the fact the driver looses control at random and vehicle veers off to the side. Putting them at risk of impacting objects near the road or veering into oncoming traffic, putting other drivers at risk. Car was brought to the Toyota dealer 11/14. They plugged it into their computer and no codes were active. No open recalls either. I went for a drive , was given 5 minutes of their time, with the shop manager and the problem didn’t present itself. They said there was nothing else they could do. There was a recall on the VSC, vehicle stability control, but that was fixed on this vehicle in July 2022. Vehicle acts like a sensor or module isn’t calibrated correctly and causes either/or braking and acceleration to be applied in a manor that will result in a crash. Vehicle is not safe to drive.

Driver side window spontaneously shattered while driving down highway at 65 mph. It sounded like a pressure explosion. My wife was driving and glass flew from f9nrt to passenger side and to the rear of the vehicle. Luckily my wife was wearing sun glasses. My duaghyers were in the rear with my youngest daugthers eyes being protected by a book she was reading. Glass struck me on the passenger side on the left side of my face.

When braking the car will start braking then stop slowing down for 1/2 to 1 second and resume braking. If you have ever braked when hitting an ice patch this is exactly how it feels. The obvious answer was an intermittent braking problem and I was delighted to hear about the recall for the stability control. We had it reprogrammed last week but when driving it home it happened twice again but for the first time when braking the car ACTUALLY ACCELERATED 3-4 MPH. This is clearly not a braking failure but a very brief intermittent acceleration of the electric motor when braking. When it occurs it is almost exclusively when making a moving right hand turn onto another road or entrance ramp. The starting speed is approx 35-45 MPH when applying the brake so when into the turn the speed is 20-25 mph and your foot is still on the brake when the sensation of the car not braking occurs and lasts approx. 1/2 to 1 second before the car starts to slow again. So the sensation is that of an intermittent braking problem but it is actually a very brief acceleration of the electric motor. Not being able to slow the car at 30 MPH for even 1/2 to 1 second the car will travel an additional 22-44 feet before braking resumes. This is dangerous and very difficult to diagnose. This is intermittent but we experience it on average every other day and on that day it can occur 2-3 times. Present since we got it new and now has 2,100 miles.
