2018 TOYOTA HIGHLANDER Forward Collision Avoidance Automatic Emergency Braking Problems

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The issue involves the Dynamic Radar Cruise Control system (vehicle-to-vehicle distance control mode) in my 2018 Toyota Highlander. This system automatically cancels when the vehicle’s speed drops to approximately 25 mph (40 km/h) or below. The system disengages without driver input during normal driving conditions such as heavy traffic or congestion. The component remains functional but poses a safety concern due to its operational design. The vehicle and system are available for inspection upon request. 2. How was your safety or the safety of others put at risk? This malfunction creates a significant safety risk when driving in stop-and-go or congested traffic. The sudden loss of adaptive speed control forces the driver to quickly resume manual braking and acceleration, which can cause delayed reactions and potential rear-end collisions. The unexpected disengagement may also confuse...

On a trip to NC on June 27 2024, then on to Hilton Head SC on 6/29, multiple system warning lights suddenly appeared on the dash including ABS, Lane Departure Warning, BSM, notifying me that those safety features were not available on the vehicle. Sometimes the the lights would disappear, especially if the vehicle was stopped and the engine was turned off at a rest area. Because the check engine light was not lit, I continued to our NC destination. We continued our trip on 6/29 to Hilton Head, and the lights continued to appear, sometimes staying on for an hour or more. I called my Binghamton NY Toyota dealer who advised me to have the problem looked. I was able to have the car seen at Savannah Toyota (GA) where they diagnosed the problem as an issue with rust and debris on the left front speed sensor. I had...

About6 months ago I started getting the messege "Breaking power low" when i try to start my vehicle. So I took it to Star Toyota Service paid $175 to diagnose the problem. The found DTC 1241 and told me to change the qhole skid control unit. Eventhough on the paper it said skid control ecu battery. So I took it to another dealer named Penn Toyota and they found the same code but they said the voltage is coming low because I may leave my ignition on before I start my vehicle. That sounds funny because I do not do this and on top if i do this my battery would be dead. As of right now I spoke with toyota and since my extended warrenty has finished so they offered my 25% coupon if i fixe the problem. Now I do not know what is the problem and which...

I am having an issue with my brake assist in my 2018 Toyota Highlander. This car was purchased new and has had regular service/ maintenance with the dealership since purchased. 1st incident was minor in nature. My brake was gently applied and the ABS feature turned on and brake system engaged without any need. 2nd incident brake was applied and at the halfway point the brake stopped working. It felt like it locked. I could not stop my car as I was approaching another car. Car stopped at the last possible moment before impact. The situation was extremely dangerous for myself, my kids and the other driver. Later on during my drive I gently applied my brake and the brake would not release to it original position until a few seconds later. This time the brake light came on. Once the car came to a stop, I shifted my gear...

Approaching a stop light brakes didn’t work. The automatic system activated and the car stopped right before I rear-ended the car in front of me. I took it to a Toyota dealership and they diagnosed a faulty brake booster pump with a price of $2500 to replace. I see this isn’t a unique problem for the 2018 Highlander but after talking with Toyota they denied any coverage since my vehicle has 48,000 miles and is out of warranty.

Where the incident happened? The incident happened at the following google coordinates (39.21707240377137, -77.6491829535095) on an unpaved, but well-maintained road. When this incident took place? 09/11/2021 – around 10.30am Who is travelling with you? I was travelling with my wife (Vijaya) and Pet Dog (Leo). Both my wife and I have the seat belts on. How are the driving conditions? A bright and sunny morning with clear visibility, minimal wind and no rain. The road is totally dry. In a way perfect driving condition. How the incident happened? A white truck came in the opposite direction and since the road is narrow I pulled my highlander to the right, where there is some loose gravel on the side of the road. When I pulled to the side I am almost at a standstill and after the truck had passed started moving the car towards the middle of the road. At...
