What’s my best bet here? Lexus parts online? Dealer? Amazon? eBay? Please let me know if anyone has any suggestions.

 

I would check eBay, Megazip or Amayama first since they will be the least expensive option.

 

ebay if you find new or used oem from a reputable seller, I hear the chinese aftermarket is garbage and doesnt work properly.

 

I ordered a parking sensor and a headlight from eBay seller triplecreations. Both were genuine, and the customer service is excellent. The only downside is you'll pay duties because they come from the UAE.

 

How do you guys get the most out of your parking sensors? When mine is enabled they go off while I’m in the drive thru. That’s annoying.

 

I just leave mine off most of the time now.

 

Pretty much all you can do is keep them clean and working... In fact my sensor is fine (maybe), when removing the bumper, unexpectedly, I discovered the wires are just cut 10 cm away from the sensor. I found a wiring end with the connector that my mechanic will weld, but too late, I've also got the sensor ($200) which will be useless. I don't know what kind of game the former owner played or if a mouse ate the cable but it pissed me off really. I would have preferred a lot having just a failed sensor to replace.

 

The strange thing is that after removing my bumper, and swapping far left (problematic) sensor with the far right, now they all seem to be working fine.
