    I got the orange BRAKE! Warning with loud beeping last night @ 80mph on the interstate, thought an animal had entered the roadway or something, there was nothing there, false alarm. Sure did get my heart pumping. Truck is a bone stock ‘18 SR 4X4 5.7 DC long bed with 6k miles.

    Happed again to me today. I think it was a true one though as I was coming quick up on someone that was turning left but my plan was to duck a bit right to get around them without stopping on the single lane street. It was wide enough to do so going into the shoulder. The truck did not brake on its own at all.

    I started having these problems with TSS pretty soon after purchasing. Its very random usually happens in foggy weather, rain , or places where trees are close to the road and hanging over the road some. My best friend of 20 years services my truck and they looked into it tested everything and calibration was good. Toyota is having trouble with this system especially on curvy roads. which make sense due to the problems I am having. They are having the same problem with the auto head lights. I use the auto dimming headlights but they are not perfect by far. Both systems are using a camera in the rear view mirror. If the weather is bad enough the pre collision turns itself off. I am waiting on any news this system is rather new. I am also waiting to do a lift kit and new bumpers until they have more experiences with it. The recall will mess with your gas mileage indicator for a little while after about 30 minutes of driving it will clear up. I will keep yall informed with any new info i get. My truck is a stock 2018 SR5 with the XP package.

    So last time it happened to me it was after a snow storm and i had some residual mag-chloride, etc on the truck for about a week. Since washing it i have not had any issues at all with the system. I have got the pre collision warning several times because i came in hot and brake late. The truck does not brake for you.
    I am lifted 3/1 with 35" tires.

    My ‘18 SR intervened with brakes once, I was on a curvy two lane road, the car ahead was turning left onto a country road at the apex of a right curve. I didn’t slow down because I knew he would be out my way by the time I reached his position. The truck freaked out and applied the brakes, hard.

    The manual states that the system may not pick up all objects and that it may only lessen the severity of an accident but it absolutely will brake for you if it thinks an accident is imminent. The sensitivity can also be adjusted by the driver.

    I had 12,000 miles with no TSS issues on my tundra that I just traded in. 3/1 Eibach lift was installed with less than 1000 miles on it. So 11,000 “lifted” miles with no issues.

    Here you go, from the 19 owners manual. I encourage everyone read the owners manual, a lot will find their issues are simply the limitations of the system. No different than other vehicles that use similar systems.

    Read it and would have an easier time accepting their shortcomings if I could just disable it for good and it wouldn't put an amber alert on the dash when you turned it off. Also I believe you have to turn it off every time you start the car as it defaults to on.

    Well it’s meant to save lives, and the insurance premiums reflect that. Won’t be long before every vehicle has a similar system, the pros outweigh the cons, 30%+ reduction in forward collisions. It defaults on due to liability, it is a conscious decision to turn it off, think about that. The average human reaction time is .25 seconds, a professional athlete is .12 seconds, the safety systems react at approximately .005 seconds... Not arguing, don’t care what others think or do.

    I can accept that then why not make it a passive system or have the option to? All these random false alarms going off do is make the operator ignore the system.

    At least in my use over the last year, very very few alarms have been false and even most of the "false" ones I observed an atypical condition that likely caused it

    I came across this forum looking for solutions/reasons to my radar "problems" on my 2018 Tundra SR5 4x4 CrewMax with a cap over the bed. I have owned the truck for 13 months. It has less than 5000 miles on it. Love the power and the ride. About 2 months after my second scheduled maintenance I started noticing little things like the front sensors going off as I passed bushes while backing out of our driveway. Then the drivers side BSM started missing vehicles or going off for no reason. Once the pre-collision braking kicked in at 50 MPH as I was coming up on a truck waiting to make a left in the center lane - caught me totally off guard. Turned off that function first chance I got. We live in the mountains surrounded by forest, gravel roads, steep driveway, etc.
    One day I let the truck gently roll back from the bottom 25 feet of our driveway (something I had done many times with my previous truck and a couple of times with this one when I forgot to get the mail). This time? RIGHT INTO A TREE!!!! Using 3 mirrors, a backup camera and the sensors missed a 10" tree!!!!! I expected to see some scratches and a dent. I couldn't believe the damage done but after the body shop got done I really started to question my choice of vehicle. Did I buy a Lego built truck? Whatever happened to solid bumpers? What kind of protection can I expect in a collision? Was I asleep for the last 14 years since my last truck?
    I paid out-of-pocket for the body work (mistake) before actually seeing the dealership (mistake) which has no body shop. Didn't know that until I called the dealership which is when I told them about my radar issue. Oh yeah, no record of the call. Now they're saying I need another almost 2 grand in sensor and bracket parts. Gotta check and see how they arrived at this diagnosis.
    Maybe I'm getting old school dinosaur but all this beeping, light-flashing, spaceship stuff is taking the joy out of actually DRIVING.

    Update - I took my trunk into the dealer three times to correct and on third time I also called Toyota corp and opened a case. They sent a tech out to the dealership from Toyota and he diagnosed the system being out of calibration and he recalibrated. So far probably about 500 miles on the recalibration and everything is great, no problems so crossing my fingers. I will say Toyota was responsive however this process to get it fixed is time consuming.

    I just got a check engine light, drive select and go malfunction, pre collision, and tow haul malfunction or whatever light. I thought it was my aftermarket tail lights that caused am issue, cause I blew a fuse, and my camera and gear selector highlight don't work. Just gotta replace fuse but I'm worried. Have you guys been having that problem? My appt is next Thursday with Toyota. Apparently they told me my compass is haywire, and they gotta keep it for a day.

    Just got my truck back, the PCS was illuminated as being not available. While it was there I mentioned that the ECU was buzzing between 1800-2K. They replaced the ECU and the buzzing was gone, but the PCS light would not come on for them. I arrived to pick it up, got 10 miles away and the PCS light comes on, back to the dealership I go. They ended up replacing the "Millimeter Wave Radar Sensor Assembly" and re-calibrated the system.

    It is very nice not to hear the buzzing anymore.

    Yes, stock suspension here, and it has only happened once right at 1,000 miles; but I only have 1,200 miles on my 2019 Tundra now. This happened at night while it was raining steadily. A car in front of me was going very slow and as we approached a divided highway and the moved into the left lane, I accelerated and got close to their bumper and passed them on the right-side. Not sure if it was because I got too close to them during passing, or if it was a combination of this and the rain/fog that night. Once I turned the Tundra off and then restarted it a few hours later, the "PCS off" light was gone and I could go into the system and turn it off/on manually and adjust the sensitivity. While it was off, I could not change these settings on my way home.

    So far I have 1000+ miles on my truck since the Toyota Corp Tech came out and recalibrated the system. Actually my PCS system has worked twice as advertised so hopefully it's corrected (fingers crossed). My advice is be relentless taking it back to the dealer (this is a total quality control issue with Toyota - make them document it) no matter how much they tell you nothing is wrong or they cant replicate it. Then call Toyota to open a case and get a regional tech to come out and look at it.

    I voted. My PCS has been unavailable for a week now. Every time I drive the truck the PCS Light will come on after 3~5min of driving. I have an appt scheduled for next week so we will see how it goes with the dealership.

    It happened twice to me today on a 6 hour trip. Clear dry 30 degree weather, both times as I went through a traffic light. Could there be something in the light setting it off maybe???
    Just momentary alarm, cruise works fine.
    2019, bone stock, 1500 miles

    Dealer "reflashed" it. So far no more false alarms - we'll see...

    UPDATE: 6 weeks and 2500 miles later no reoccurrence!

    My radar cruise control quit today twice on my brand new 2018 Tundra TRD Sport with only 540 miles on it. I was driving in dense fog on a wet freeway. It told me the sensor needed cleaning. The sensor is behind the Toyota emblem in the center of the grille. So I wiped it dry, shut the truck off, restarted it and went on my way like normal. Everything worked fine for the next 15 miles and then *bam* happened again. So I pulled over and repeated what I did the first time. Got out out of the fog a little bit later and when I got to my destination I bought some RainX. Applied it to the emblem (The RainX chemicals haven't attacked the plastic as of yet and it's been 12 hours) and drove home. In the last 15 miles of the trip home I was back in dense fog again and the problem never came back.

    Both times the problem happened, I had water droplets all over the emblem (which covers the radar antenna). Radar frequencies are sensitive to moisture and the higher you go in frequency, the larger the effect. The RainX doesn't allow the water to adhere to the surface it's applied on so that's why I reached for it first. So far it's worked! 15 miles might not be much of a test but it's all I've got for now. Hope this helps!

    Thinking that if this also affects the sensors behind the rear view mirror then RainX might also be indicated for application on the windshield as well. Buy some of the concentrated stuff and apply it on the emblem and windshield and then get some windshield washer fluid with the stuff so you constantly apply it to your windshield with every squirt. If this is indeed the solution then this would be the way to maintain it. I'll let you guys know if it ever fails during better testing conditions going forward. Thinking a good steady rain, road spray, fog, etc. would provide the hard answers to this possible solution.

    We had 3 PCS Malfunctioning errors over 3 weeks. I’d shut the truck off, let it sit overnight, and the error would go away.

    However after the last time, we did take it to the dealer. They immediately kept it and gave us a rental while they ordered and replaced the radar sensor.

    Every morning I start my truck there is the precollision warning but just lately I’ve been getting the “brake” message with nothing in front of me.

    All stock, and works as should be. I love the system.

    Currently waiting on the regional Toyota Corp Technician. The original PCSS was replaced in mid December due to frequent radar unavailable warnings. Returned to the dealer last week due to two unintended braking. Both occurred within a week and on clear days. NO modifications to the truck.
    Dealer immediately opened a case with Toyota and provided a rental. Love the truck, happy with the dealer's transparency, but missing my 2002 Tundra (300K+). Will post once I hear from the TOY Tech.
