Default Switch, Stop Light - Replace? *CHECK ENGINE LIGHT CAUSE*

Hello,

All the indicators on my dash recently came on (stays on), so I brought my 2007 Lexus IS250 into Lexus for diagnosing (they charged me $180).

They found the problem to be:
# G BE92 Switch, Stop Light - Replace 193.90 *CHECK ENGINE LIGHT CAUSE*
And says it will be about $200.

Does this sound reasonable? What do you recommend?

The brake/stop lights (two side and middle lights) all currently still work fine.

Thank you so much for your input!



Dashlights On


Codes from Lexus

Are your tailights staying on once the car is turned off?

Stop Light Switch is $13.15 on Rock Auto.com Beck/Arnley

It's an easy fix.

​​​​​​You brake pedal arm should make contact with the plunger. You'll have to look up under the dashboard.

Once the car is turned off, my car's front and back lights stay on for a few seconds before both turning off - or if I lock using my remote then all my lights turn off immediately.

Would that be an OEM switch or after market?
I looked at this (not sure if it's the right part): https://www.autozone.com/electrical-...121_0_0?review
But a review said it disabled their cruise control.

As you might be able to tell, I am not the most autoparts savvy person so I really appreciate the help!

The autozone link you posted is correct. It would be considered aftermarket. I assume denso should be OEM. As to why it would disable the cruise control using after market. Is beyond me maybe on that part. A wild assumption would be if it's not it the correct possition. The plunger would activate the brakes when cruise control is engaged.

The lights staying on after shut down is normal. My question was that if just the tail lights stay on by themselves. That's a clear sign of a failing stop switch. They would just stay on while the car it shut off.

In that case no, the lights work perfectly fine, turns on and off at the correct times! So, would you recommend that I buy the part and just replace it myself? Is there a chance that the dash still will not clear? Thanks!

It's up to you if you feel confident to change it. Just try to get a measurement of the plunger position before you remove it. Of how far it sticks out of it's housing. Then once installing the new one try to set it at that same distance.

Probably on YouTube you can find many tutorials. Honda's are notorious for this failure brake swich always going bad.

For what it's worth, Lexus extended the warranty on certain components as part of the class action lawsuit in 2010 including the stop light switch.

This part should be covered under this extended warranty program ELL in the USA.

Hm...I've done some work on my cars using YouTube videos before, but usually easy stuff like changing lights or installing a new battery.

I should probably going to a professional for this in case I manage to somehow blow up my car lol

What is would you say is a reasonable price?

Thank you thank you!

Thanks!

The brake lights were working fine to my knowledge, so...
Oh my, what was your resolution? Interested in knowing, thanks!

The switch looks to be the culprit.
