2022 Toyota Highlander

Component or system that malfunctioned: The braking system on my 2022 Toyota Highlander Hybrid, specifically the transition between regenerative braking and hydraulic friction braking, appears to malfunction intermittently. During braking, the vehicle sometimes lurches or surges forward instead of slowing smoothly, especially at low speeds or when braking downhill. The vehicle is available for inspection upon request. How safety was put at risk: The unexpected forward surge while braking increases stopping distance and creates uncertainty about braking performance, particularly in traffic or parking situations. This creates a risk of rear-end or low-speed collisions and reduces my confidence in the braking system. Problem reproduced or confirmed by dealer or service center: The vehicle was inspected by a Toyota dealership, and a Technical Service Bulletin (TSB) software update intended to address braking behavior was performed at approximately 50,000 miles. However, the braking problem continues unchanged after the repair. I had to pay the dealer to perform this TSB update. The dealer was initially reluctant to apply the TSB and did not associate my braking complaint with the known issue. I had to research the TSB myself and request that it be applied. The invoice notes that the dealer reproduced the issue. Vehicle or component inspected by manufacturer or others: The vehicle has been inspected by a Toyota dealership service department. It has not been inspected by police or insurance representatives, as no accident has occurred. Warning lamps or prior symptoms: No warning lights or messages appear when the problem occurs. The issue happens intermittently without warning and has occurred since the vehicle was new. The condition appears to be getting progressively worse. The issue seems more likely to occur when braking while the hybrid battery is near or at full charge, suggesting a possible problem in the transition between regenerative and friction braking.

The contact owns a 2022 Toyota Highland. The contact stated that while at a traffic light, and depressing the brake pedal, the vehicle experienced unintended acceleration. The contact stated that the failure had occurred on several occasions. The cause of the failure was not yet determined. The local dealer and manufacturer was notified of the failure. The failure mileage was 13,000. The contact stated the vehicle had a similar incident while in park, lurching forward as if trying to drive.

The breaking system doesn’t take effect in speed and turn and when you leave the acceleration and the speed increase and loose control . Also the electrical system is damage not with seven month of brand new highlander hybrid . The rear cross traffic control and blind spot warning are coming . These is a serious electrical problem under 11,000 miles brand new vechile

According to Toyota, the wire harness needs to be replaced due to damages caused by animals (rodents). My main concern is, this vehicle is not safe to drive. Because if a midsize animal could find its way inside the engine compartment and caused so much damages to a car I drive every day, what would happen if a snake or a rat shows up inside the cabin while driving at 65 or 70 mph. Secondly, what types of materials are used to make these wires and other components in the vehicle? Why are these animals attracted to them in the first place? As much as the news was chocking to me because it was the first time that I have heard of that kind of stuff, when I went online in some Toyota owners forums, that issue is prevalent in Toyotas. Even the rep. from Toyota whom I spoke to earlier stated that her cousin who owns a Toyota had to deal with the same issue. Why nothing has been done to fix the problem?

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.

The contact owns a 2022 Toyota Highlander. The contact stated that while her partner was reversing out of a driveway, the vehicle independently surged backward up a hill as her partner applied the brake pedal. Her partner was able to place the vehicle into drive which sent the vehicle forward. The vehicle hit a tree which stopped the acceleration. The contact heard screaming from inside her home and called 911 for assistance. The air bags did not deploy. Her partner was taken to the hospital for an examination and suffered no injuries. A police report was not filed. No property damage was reported. The dealer and the manufacturer were both notified about the failure, the vehicle was towed to the dealer for an impending investigation. The vehicle had yet to be repaired. The failure mileage was unknown.

The contact owns a 2022 Toyota Highlander. The contact stated while driving 35-40 MPH and attempting to accelerate to enter the highway, the accelerator pedal was depressed; however, the vehicle responded sluggishly. The vehicle emitted abnormal sounds as though the transmission was in neutral. The contact depressed the accelerator pedal all the way to the floorboard and the vehicle responded as intended. There were no warning lights illuminated. The contact was able to continue driving. Additionally, the contact stated that while driving 40 MPH, the brake pedal was depressed but hesitated to respond, causing 20 feet stopping distance delay. The contact stated that the failure mainly occurred in wet conditions, snowy conditions while driving approximately 60 MPH. The vehicle was taken to the dealer and test driven. The dealer informed the contact that though the vehicle was sluggish, it was not concerning. However, the failure reoccurred increasingly. The vehicle was taken to the dealer for a second and third time. The dealer test drove the vehicle and informed the contact that they could not duplicate the failure. Additionally, the contact stated that there was a strong burning wire coating smell coming from grill radiator while driving approximately 60 MPH. The contact stated that there was a metallic rotating sound coming from the air conditioning vent while using the heat. The contact stated that the sound persisted after turning off the vehicle. The contact also stated that there was an abnormal sound coming from the rear passenger’s side subframe while reversing. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and a case was opened. The contact was awaiting a call back. The failure mileage was approximately 1,800.
