Recall: Pre-Collision System (PCS)

We have had our Tundra for 6 weeks. Its never flashed any warnings or applied brake automatically. We have not had any incidents that would have warranted such action so I guess its working. The dynamic cruise works and it uses the same radar I assume.

 

Have had my ‘19 for only 500 miles, but I also haven’t had it engage yet.

 

No, the big orange brake light comes on and then the truck brakes dramatically on its own, just shy of slamming on the brakes....that is a safety issue. it happened to me once before the recall. Scared the !@$%*! out of me.

 

You and me both. I’m not going back to stock. That’s the whole point of owning the truck is to do what you want. Lol.

 

Yeah never made sense to me. Clear Toyota of all liability because your truck is lifted due to water getting in a sensor.

 

I hope my replacement truck is trouble free.

 

This makes no sense. If PCS deactivates the truck does not brake.

 

I'm getting ready to install an older style PRO grille on my 2018 Off-Road. What would happen if I just leave the sensor off the truck all together? I'm assuming a dash light, but is there any way to clear that?

 

Don’t know but curious also?????

I someday want to do a lighted emblem

 

Doesn't matter if it makes sense, it happens.

 

I had the recall completed. They made me sign a form saying I acknowledge that I shouldn't rely it and it may malfunction since I have a lift and bigger tires.

Got in my truck to leave, and found this stick to my steering column.



Kinda pissed me off. I heard your speech, I signed your form. F off

 

During my first year of ownership with my 2018, I had maybe 4 or 5 phantom "BRAKE!" alerts. Nothing in front of me. A couple times, the PCS system would go offline during heavy rain.

So I get the recall done about a week and a half ago. I haven't had the PCS go offline, but I've had about 7 or 8 phantom "BRAKE!" alerts. So whatever they did during the recall made things much, much worse. I just made an appointment with the dealer. Presumably they'll have to order parts. I'll be damned if I'm walking out of there without a satisfactory resolution, though.

Technology is so, so stupid, and it boggles my mind to see people complain to Toyota about how the Tundra "is light years behind" the other manufacturers. Yeah, great, let's pack our trucks full of useless nanny garbage that doesn't work. Great idea. Ok, end rant.

 

Yep. Mine is worse. See my post above.

 

Did it ever actually apply the brakes for you without you expecting it or it just screams and flashes at you? I've never had it actually apply the brake in error when it fails.

 

We have not had the PCS activate on our 2019 Tundra and we have had it for about 3 months. I couldn't tell you if its on/off working or not. Glad I have not had phantom braking that would not fly. I'd take the dang thing off the truck.

My Honda accord has a similar system but it is a passive system. Only flashes a dash light and then a heads up display in the windshield when it really thinks you should brake. It does not brake on its own thought. I am glad it does not. I would rather just have the passive system. I don't like the thought of my car braking or driving for me.

 

Mine never engaged brakes on its own. It simply beeps and flashed on the dash -- this in turn disabled the Adaptive Cruise Control. If you have adaptive cruise control and it's working, you aren't having the problem others are describing.

 

I got a 2019 a few months ago and its beeped a couple times to brake, but never applied brakes.. One day in heavy rain it disabled itself, which ticked me off because I couldn't use cruise any more.. Now I am waiting on parts to do the recall and I'm concerned it will be more sensitive, I hope it is not. Thinking about adding the TRD Pro grill at the same time as the recall work..

 

My question on this entire ordeal:

If there is an issue with the height, how is it that the sensor is in 2 different spots on a pro grill vs. normal grill. If the sensor was height specific, then doesn't it make sense that if you had the normal grill, change to a pro grill and raise your vehicle 1-3", you will essentially have the sensor in the same spot as where it was before you lifted the truck??? In my case, thats essentially what has happened...

With that being said, I think the whole height issue is nonsense, since toyota has multiple versions of the sensor mounted on the same model at different stock heights...

 

So far, it has not applied the brakes on it's own. I admit I am nervous though, with the increase in false alarms I'm getting, can I trust it to never apply the brakes? I checked the owner's manual, beginning on page 238, there 4 pages of reasons why the thing might give false alarms or not function properly. It looks like Toyota threw every reason they could think of in there just to say "See? Your problems are just part of the feature." The very first reason - "Conditions under which the system may operate even if there is no possibility of a collision - When passing a vehicle or pedestrian." Are you kidding me?

 

You can still use cruise control if the radar system is off line. Engage cruise control like you normally would - the only difference is you hold the cruise control start button, and after a few seconds of holding, it bypasses the adaptive cruise control and you can use regular old fashioned cruise control.

 

I just bought a 2019 and had the dealer turn the ignition cycle off for the PCS. If I turn the PCS off, it stays off no matter how many times I turn the truck on or off. They didn’t charge me a dime for it or make me sign any waivers or put any stickers on my steering wheel.

I plan to lift the truck myself sometime in the future once warranty is up. If the sensor gives me issues, I’ll just turn it off and leave it off.

 

By the way if you didn’t see my post above, the 2019s can definitely be set this way too, they did it on mine. Don’t let the dealer tell you otherwise they’re full of shit and just don’t know how to or are lazy.

If you didn’t see my post above, the 2019s can definitely be set this way, they did it on mine the day I bought it. Don’t let the dealer tell you otherwise... they’re either full of shit or just don’t know how. The treatment some people get from dealerships is amazing. This is not how to treat a customer.

 

The sensor on the pro grill is a few inches lower than the standard grill because the pro is a few inches taller. The are basically the same height off the ground because one is lifted the other is not.

 

Does the offset in height account for the difference or is it an arbitrary height on the vehicle due to things like settling, extra weight, etc? Is it really an exact difference, does the need for a change in height +/- 3” really need to be a concern for Toyota to not perform the tsb, or to state the mods will cause it to not work correctly?

 

I purposely waited for these recalls before doing any mods to wheels or lift. The result? I didn't have to sign a waiver, or listen to a speech, when I took my truck in... AND, my sensors will function properly with a lift. Patience is a virtue. The dealer told me the waiver comes into play with people that already added larger tires and lifts; they can't guarantee the calibrations.

 

So, they calibrated them before any lift? And they are going to work perfectly after a lift?

I'm glad they did it, so now they are calibrated with my lift and tires.

 

I took my truck in yesterday for my 5k mile maintenance and they addressed the recall while it was in. I have a 2017 Pro grille on my 2018, with the Jomax sensor relocation kit. They gave me the "you've made non-approved modifications" form and said they have filed a report to Toyota to void my pre-collision system warranty. They also stated they would be placing a "non-removable" sticker on the dash and two dash lights would remain on indicating that the PCS was deactivated. I pushed back pretty hard against all of that, and said I didn't give them permission to add anything to my truck, it was here for a multi point inspection and tire rotation.

After about 20 minutes of arguing with the service rep, and him telling me that I had a "blocking plate" over the wave sensor so it wasn't working properly anyway (which was the shield provided by Jomax to protect the sensor), a service tech came out and said all I needed to do was put the factory grille back on and bring the truck back so they could clear the warranty, then I could do "whatever I want" after that. Just an absolute joke by Toyota that they're making this out to be a much bigger deal than it is. I understand I modified the truck, just say you're not going to do the recall and move on.

I'm putting my TRD-Pro suspension on Friday, can't wait to hear the parental lecture from the dealer when it goes in for the 10k oil change.

 

I don’t understand that. They can’t touch people trucks without permission. Especially if they are attaching permanent stickers and making annoying lights stay on.

 

The service technician was actually a cool guy, and was lucky enough to be part of the argument between me and the service rep / manager. The service manager said they had never dealt with someone doing such "advanced" modification to the PCS, and were just following what Toyota had advised them to do in this situation. The service tech laughed and said, "he just put a bracket in here to hold the wave sensor because the Pro grille doesn't have a place". All said and done, the tech helped me out, he "placed" the sticker on my center console, which I promptly threw away. Still ended up with a PCS check light on, but I guess I'll have to put my old grille on for 30 minutes and run it back down there if I want that to go away.

 

It would be useful to keep a list of dealerships from this thread that were helpful in regards to recalibarating PCS for folks with lifts, grill mods, etc. I have both and I'm not looking forward to calling the nearest 10 dealerships to ask if they can recalibrate PCS on a lifted truck!
