2016 GS 350 AWD. Located in Toronto Canada. All warnings and dash light listed above triggered altogether upon starting the engine earlier today in -6 degrees Celsius, none of them were present on my last drive.

I’m thinking Speed sensors, ABS sensor, or wheel bearing.

I drove the car around the block, The car drives fine, no unusual sounds or driving dynamics. A failed bearing using makes a grinding sound.

would it best to have it towed to my independent mechanic?

 

Other details to add:

2016 Lexus GS 350, AWD, ~173,000 KMs.

the car is new to me. To date I have done oil change, cabin and air filter, spark plugs (for peace of mind).

I plan on doing the following:

- Transmission fluid drain and fill or perhaps drop pan and replace filter (has never been done)
​​​​​​- Front and Rear Differential fluid replacement
- Brake Fluid Flush
- Coolant flush with new water pump

Thoughts on my planned maintenance route?

 

Likely it's a wheel speed sensor. You should have the car Scanned to get the codes. That would help some.

Also try disconnecting the battery for 10mins, reconnecting then drive to see if they are still there.

 

I have a basic scan tool from Amazon that I will try to pull the code from.

was planning on doing the battery disconnect and reconnect trick, hopefully that does it.

Given it is a wheel speed sensor, I reckon the issue will resurface? The warnings make it seem something catastrophic has happened

 

Disconnected the battery, left it disconnected overnight. Warnings went away then came back on after a short drive.

I am scheduled to make a visit to my mechanic in January. Anyway for me to diagnose it absent scan tool? Not sure if the car is safe to drive or cause further damage. I’d prefer having a diagnosis and order parts accordingly
