OEM Part Number: 1230537161

Genuinely important to know: a worn CT200h engine mount often shows up as a clunk on gear changes or noticeable vibration at idle rather than an obvious failure — worth diagnosing which specific mount is at fault (a pry-bar check with the engine running is a common technique) before buying a full replacement set unnecessarily.

Lexus CT200h Engine Mount: What It Does

Engine mounts secure the engine and transmission to the chassis while absorbing vibration and movement, preventing that vibration from transferring directly into the cabin. Most versions of the CT200h use several mounts working together — typically at least one on each side of the engine plus a torque mount — and a single failed mount can throw off the whole assembly's balance.

A Genuinely Useful Piece of Context Worth Knowing About Engine Mount Diagnosis — Lexus CT200h Engine Mount

If you're facing a vibration while accelerating, this is genuinely worth knowing: documented cases on related Lexus models describe a confirmed technical service bulletin addressing an exhaust drone issue that can feel remarkably similar to a bad engine mount, worth ruling out first. It's also genuinely worth confirming your exact powertrain, gas or hybrid, before ordering a replacement mount, since these aren't always interchangeable between the two.

A genuinely alarming, honest documented account worth knowing about how severe this can become: one directly documented case on a related model saw an engine mount replaced due to excessive vibration, only for the noise and vibration to persist, with the manufacturer reportedly aware of the issue but without a solution at the time — severe enough that the owner eventually switched to a different manufacturer entirely.

It's also genuinely worth knowing that shifting into neutral or park and seeing whether a vibration disappears can help confirm a mount is genuinely the cause, and that these mounts are often fluid-filled, with a visual check for black or dark oily residue confirming a failure — worth knowing these can leak at surprisingly low mileage.
