2018 TOYOTA HIGHLANDER Complaints

I have a power steering warning light. Steering is harder than normal. I believe this vehicle is having the same power steering problem that Toyota Tundra and sequoias are having. I want it to be recalled and paid for by the manafacturer. This is ridiculous a well maintained vehicle.

Vehicle will not start. "brake pressure low" message appears on instrument panel. The truck will be sent to the dealer. Brakes worked fine previously and brake fluid is at maximum level.

The contact owns a 2018 Toyota Highlander. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power after coming to a full stop at a traffic light. The vehicle was taken to an independent mechanic and the dealer; however, the mechanic and the dealer were unable to duplicate the failure. The contact related the failure to a faulty Auto Start/Stop feature. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 50,000.

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 to park and the brake light disappeared. The car was then sent to a service station for analysis. Service Station advised that there was a hissing sound coming from the front of my engine when the brake was applied. They recommended that I send vehicle back to dealership as they concluded that the car has a brake assist issue. The car was towed to the Toyota dealership where they mentioned that there was a recall for this exact issue however, my specific VIN is not included. I travel everyday with my kids and this is a real safety issue that needs to be addressed. No car should be on the road with faulty breaking systems. This can cause unnecessary loss of life. These vehicles should be included in this recall, especially mine. I filed a case with Toyota and am waiting to hear back from them. Please help make the roadways safe. Consumer stated diagnosis was completed and relayed that there was a brake booster failure. The brake master cylinder and brake booster system will need to be replaced.

Low brake fluid pull over immediately warning ??,vehicle engine shut off would not restart was on highway going 55 mph .Had to get vehicle towed . There was a recall on brake booster but my Vin was not included same model year 2018

The car Low Pressure Break pop up and lock the break because of "Low Pressure Vacuum pump" unable to Break crashing into the curve when back up. after stop the car the car wouldn't start up again.

Transmission case is porous. Toyota calls transmission oil moving through housing, weeping, not leaking and is not a warranty. Toyota dealers hide the porous condition with a coating. Regular underbody car wash removes the coating. Catastrophic failure possible.

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.

Car wouldnt start in garage, it shows error in the dash "Braking Power Low, STOP in a safe place". It looks like several people are having same issue around same time outside of warranty, and on cars not in the original recall.

MY 2018 Toyota Highlander XLE had a break malfunction April 15, 2022. The Brake light illuminated, "low brake power" flashed briefly and the pedal became stiff and unable to press for braking. I swerved to avoid rear ending the car in front of me. Brought it in to Toyota and they want $2000 to fix the break booster vacuum, and said it is not covered by warranty. My car only has 46k miles! This part is clearly faulty and Toyota should replace it. Accordingly to Toyota vehicle Maintenance Schedule, the vacuum pump for the brake booster needs to be replaced as a regular maintenance or "wear" item every 120,000 miles. This is a very expensive maintenance item (>$600 in parts, ~$2000 including labor and shop materials), that needs to be performed by a Toyota certified technician. In addition to being very expensive, what will discourage many vehicle owners from performing this service, one may expect that many owners who perform their own vehicle maintenance or use independent mechanic shops will simply miss this service altogether. Being a safety critical item, the vacuum pump should be designed to last the entire lifespan of the vehicle (just like other brake system components: ABS pump, vacuum booster, master cylinder, etc.). The short lifespan of the vacuum pump and the requirement to replace it on a regular basis is indicative of a defective or deficient design. Making the replacement of the vacuum pump a scheduled maintenance item is a just way for Toyota to avoid liability due to premature failures of a substandard safety component, especially in light that other brake system components are designed to last for the entire life of the vehicle, and are not considered wear items in the maintenance schedule (except for brake pads, of course). Toyota should redesign the vacuum pump to increase its lifespan in-line with the rest of the brake system components, and perform the replacement under a safety recall or service campaign, at no cost to vehicle owners.
