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 the recommended service performed. The service report says that I requested replacing the ABS sensor, which is totally false, because I had no idea what the problem was, I just wanted it fixed. The part was ordered and replaced the next morning. All the lights were back on the next day when I drove back from Savannah to Hilton Head. I did not have time to go back to the dealer, but did notify the service manager of the situation. I drove the vehicle back to NY with the warning lights on (most of the time). I now have a service appt with my local dealer on 7/9/24 to determine the next step.

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.

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.

The pre-collision system failed to assist in avoiding an accident when the car in front of me stopped suddenly in traffic on a highway. Since the repair, the brake warning indicator light on the speedometer side of the instrument cluster intermittently illuminates and the brake pedal pulses as if the ABS system is engaging. Once it stopped me suddenly while driving down a busy city street. Went from 35 to 0 very suddenly. I have taken this to 2 dealers and they say there is nothing wrong. The system does not indicate an error even though the light is on and they tested while it was on. I can recreate the issue by accelerating quickly while turning left. Sometimes it happens when going straight, but the only way to guarantee it will happen is to turn and accelerate quickly. Neither of the 2 dealers I have taken it to have found the issue and toyota customer care stopped calling me back.
