Millimeter wave radar sensor recall denial

You won't catch hell from me as you are correct. If memory serves me correctly it is 49 CFR part 581.

 

I'm not seeing the problem here. You posted the flow chart that clearly directs the dealer what to do. They did what they were directed to do. What is the issue?

 

If you look at the flow chart, it directs them to the modified vehicle job aid, but for grilles and lifts. For aftermarket bumpers, there is nothing they can do as of yet.

 

But that heavy ass bumper is going to affect the braking distance of the truck. The sensor would need to be calibrated for the additional space it would need to stop. Therefore the sensor is just as susceptible to malfunction or at least not acting as designed.

 

Is Toyota worried about the angles? If so what if the TSS malfunctions due to hauling a heavy load or towing a heavy trailer? Within its specs of course.

 

Two 300 pound occupants will cause the front end to dip just as much as that aftermarket bumper and one 150 pound occupant. I get it the rules/flow chart is what it is. I still think in this one case it's silly. But what I think does not matter.

Never mind, I am wrong.

 

I'm sure the system is calibrated for some upward front end movement for towing a trailer. When people start adding lift kits even a 1.5 inch left can turn into feet over a long distance. I tried explaining this in another post, but it went completely over people's head because they can't think any further than the measurement at the sensor.

 

It's all based on numbers of probability.

 

I hope none of you people ballast airplanes or ships for a living. The weight is hanging over the front axle so basically none of it is being shared by the rear axle.

 

I get that. Hence the reason for 600# of people in the front seats to make up for the weight behind the front axle. As a side note, 300# occupants these days are not unusual.

Never mind, I am wrong.

 

Well if thats the case then what about toppers, campers, RTT, loaded toolboxes etc???

Seems Toyota will allow weight in the back which would affect the TSS yet won't allow anything in the front end which is less likely to affect it.

Why can't Toyota calibrate the TSS to allow for lift kits (say under 3") heavy bumpers and non oem grills?

I thought they were worried about moisture getting into the TSS?

 

Do you remember which thread it was? There have been a few on this issue. I would like to see the calibration procedure. I apparently missed it.

 

And? If you had a Sienna minivan and did the same thing would you install an aftermarket bumper?

Times are changing. People want all this crap and they got it. That's fine. If you want to mod eventually you have to go to older vehicles. I have a new Tundra with zero mods and will never mod it. I am looking at a 1978 C10 step aside lol and I will mod the hell out of it. That's just how it is now.

Or, you can buy a new truck and just blow off any warranty and mod it how you want. 10" lift, solid axle, roll cage, bumpers, winches on both ends, whatever you want but don't expect any warranty or recall help.

 

The bed and tow capacities are in the owners manual. I'm sure Toyota calibrated for the max load in the back and in the cab on a stock vehicle. With lift kits, etc there's too many unknown variables that Toyota has no control over like spring rates.

 

Thank you. I'll search for it as well.

 

I read it but don't remember which thread either. It is extremely detailed and every single model with a different grille has a different procedure. It cannot have any metal below or around it. The tolerances are such during calibration that air pressure in tires must be correct.

 

Okay, thank you all for the info. My first visit is in July. Fingers crossed but won't be surprised.

 

Guys.....please stop messaging me about buying my 2017....it is not for sale. I don’t care if you wanna buy it for $125,000.

 

Does Toyota have control over how much weight aftermarket front bumpers weigh?

 

Were snowplows listed? Here is a Toyota dealer peddling 3rd gens with Fisher snow plows (or vice versa).



I would like to see what Toyota says about snowplows since they are a popular combo in snow country.
