2018 Volkswagen Tiguan: what breaks, and when
A free preview from Milo. A history report shows one car's past — Milo shows the whole model: which one to buy, what breaks, and what to knock off the price.
5/10
A practical, well-packaged crossover let down by the 2.0T EA888 engine's premature timing chain/cylinder head failures — great to drive for the segment, risky to own past 80k without a paper trail.

🎯 Negotiation ammo — walk in knowing this
Free. The seller won’t volunteer any of it.
- 💸 Budget for this: Cylinder head/valve failure from timing chain stretch, sometimes catastrophic internal engine failure (rod through oil pan reported) — $6,000–$10,000 if it goes. Check it on the test drive; if it’s near due, negotiate it down.
- 🧾 Your opening line: “2018 Volkswagen Tiguans have known issues around this mileage — here’s my number.” Milo’s full report hands you the market price and a line-by-line offer script.

Which one to get — and which to avoid
✅ The one to get
A 2018 SEL Premium or SEL Premium 4Motion with full documented dealer service history and proof of every oil change on time — the extra features are a bonus, but the paper trail is what actually matters on this generation.
🚫 Avoid
Any high-mileage (80k+) Tiguan with spotty service records, especially one that's had 'occasional' quick-lube oil changes instead of VW-spec 502.00 oil — sludge and tensioner failures cluster around neglected maintenance.
