Pre collision assist issues

i bought a brand new 2019 tundra in February (2.5 months ago). I didnt even have it a for 2 weeks and before it hit 1000 miles I started to get the intermittent pre collision assist warning on my dash. At that time I still had the stock tires and rims. About a week later I got after market rims and tires put on it. I stayed with 18” wheels and the tires are the same height but a bit wider. Originals were P255/70R 18 and went to P275/70R 18. Toyota won’t fix it because I have aftermarket rims and tires. They said it the height is altered. Now I have to put on my old rims and tires before they will correct the recall. Both sets of tires were 70R 18s. I even measured them and they are the same. Sounds like a big pain over nothing. From what I read that tss system is more of a pain than its worth. Toyota should have planned that add on a lot better than they did. Other than that I love my truck.

 

Yeah what Toyota is doing is bullshit! Replacing a sensor that leaks has nothing to do with bigger tires or a lift. I don’t understand why they are not sealing the sensor. What’s next? Toyota not fixing the cam leak because of tires and lifts? It’s starting a bad precedent

 

I would document to the dealership, and copy Mama Toyota, that you came in for the SAFETY SYSTEM RECALL FIX and they refused to perform the service.

At the bottom of your notice/letter put the following "cc: Smith, Harrison, Iverson and Tremble, P.C."

 

Agree with everything above but 255/70/18 are not the same diameter as 275/70/18. They are over an inch taller and why Toyota won't do the recall. Again, also think it's BS so I agree

 

Just saw that the new 2020 Highlander is going to have "TSS 2.0"

-- Whether they’re young families or empty nesters exploring a new chapter in life, safety remains the top priority for Highlander customers. Toyota Safety Sense 2.0 comes standard in all models in the 2020 Highlander. This comprehensive active safety system includes:

• Pre-Collision System with Pedestrian Detection (PCS w/PD)
• Full-Speed Range Dynamic Radar Cruise Control (DRCC)
• Lane Departure Alert with Steering Assist (LDA w/SA)
• Automatic High Beam (AHB)
• (New) Lane Tracing Assist (LTA)
• (New) Road Sign Assist (RSA)

Will likely fix a lot of the isssues. Oh well... hope my 19 I'm picking up next week does ok

 

The recall involves applying a piece of foam over the vent holes on the sensor and updating the software in the sensor. If there are codes present, the sensor gets replaced and the new sensor can't be installed and calibrated properly with the tools provided since it isn't at a stock height.

This is Toyota's official statement:

 

Well, that rules out the possibility of 75% of Tundra owners getting the recall performed.

 

How many threads are there on this now?

 

Haha I already sold my stock wheels and tires. Went an inch taller and planning on FOX 2.0s in a couple of months. If this ever happens on my truck I guess I’m SOL.

 

I’ve seen dealers selling new lifted truck trucks. do they just tell the person that buys them. I
Know it’s a New truck and all, but your TSS system may malfunction and their is nothing we can do!

Thinking about selling my 18 and buying a 17! Love the truck but I don’t want to have these issues all the time!
