2016 RX350 suspension squeaks when going over bumps

Is the suspension to be lubricated? Has 50,000 miles.

Thank you.

Possibly, might not completely cure the noise. If it’s in the rear suspension there’s a TSB that calls for a replacement of the rear trailing arms.

Could be dry stabilizer bar bushings. Silicone grease can help that. Could be a spring rubbing on something.

Lexus got best warranty in luxury class. Did you buy a branded title? If not, just take it to a dealer and have them fix it for free

The warranty expires at 50,000 miles.
