🎯 Negotiation ammo — walk in knowing this
Free. The seller won’t volunteer any of it.
- ✅ Verify this recall: Electronic Power Steering (MDPS) connector corrosion causing intermittent loss of assist. Make the seller prove it’s been done — an open recall is money off the price.
- 💸 Budget for this: Sudden engine stall/loss of power in traffic, root causes ranging from knock sensor detonation to oil starvation from carbon/sludge buildup — $3,000–$6,500 if it goes. Check it on the test drive; if it’s near due, negotiate it down.
- 🧾 Your opening line: “2017 Hyundai Elantras 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
2017 Elantra Limited or Eco with the 1.4T engine, sunroof, and a documented history of on-time oil changes — the smaller turbo engine sidesteps most of the Nu engine drama and Limited trim adds worthwhile comfort features.
🚫 Avoid
Base SE with the 2.0L Nu engine and spotty service records — this is the exact combination generating the bulk of stalling/knocking complaints, especially if maintenance records are missing.
