OEM Part Number: confirm via VIN — engine mount (aftermarket) Febi 174056 / Febest HYM-D3RH

Accuracy note: Covers the Hyundai Tucson (2015-2020) as listed in the UK aftermarket catalogues. Engine mounts are sold by position (left, right, front, rear, upper, lower), and the right one depends on the engine, the gearbox (manual, automatic or dual-clutch) and the trim. The references below are examples from the UK aftermarket catalogue for the engines checked on this generation, so match your own engine code and gearbox before ordering; the carmaker's own numbers are not quoted in those listings, so check the genuine mount against your VIN if you want a guaranteed match.

Confirmed: A Genuine Technical Bulletin Worth Knowing About on Hybrid Models — Hyundai Tucson Engine Mount

If your Tucson Hybrid has an unusual engine noise or vibration alongside any concerns about oil condition, this is genuinely worth knowing: Hyundai has a confirmed technical bulletin (referenced 23-EE-002H) specifically addressing engine oil dilution on hybrid models, resolved through an ECU software update. If you're experiencing anything unusual alongside oil that seems to be increasing between changes, it's genuinely worth asking a dealer directly whether this specific update has been applied to your car.

A genuinely honest, real account worth knowing about before accepting a "normal" dismissal: one documented case saw a Hyundai technician test drive a Tucson Hybrid, compare it against another vehicle with the identical engine combination, and conclude that vibration felt at a specific RPM range was simply "a normal characteristic of model vehicle with engine combination" — despite the owner remaining genuinely skeptical, having noted the car ran "buttery smooth" for the first 25,000km before this vibration developed. If you're told something is simply "how they all are" despite your own car previously feeling different, it's genuinely worth continuing to document the issue and pursuing it through Hyundai's consumer affairs channels rather than accepting the dismissal outright, particularly if you have a clear before-and-after comparison like this.

It's also worth knowing that a proper diagnosis for vibration or unusual noise should genuinely involve inspecting all engine mounts, the belt tensioner assembly, the drive train, and exhaust mountings together — worth asking specifically whether all of these were checked, rather than accepting a vague "test driven and found normal" conclusion without documented detail on what was actually inspected.

Hyundai Tucson 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 Tucson 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.
