2015 Hyundai Elantra vs 2015 Kia Soul
Two compact cars, compared on what actually matters when you're buying used:
what breaks, when it breaks, and what it costs you.
2015 Hyundai
Elantra
4/10
The 2015 Elantra is a fine-driving, feature-loaded econobox undermined by a well-documented engine failure epidemic; the good ones are great, the bad ones grenade at 70k.
VS
2015 Kia
Soul
6/10
Great personality and value if you get the 2.0L Nu engine checked for the bearing/knock recall — skip it entirely if that recall hasn't been done.
Milo scores the 2015 Kia Soul higher — 6/10 against 4/10.

If you buy one, buy this one
✅ 2015 Hyundai Elantra
A 2015 Elantra GT hatchback with the 2.0L, 6-speed manual, and Style/Tech package — from a dry state, one owner, complete service records, KSDS flash and all three recalls closed. For sedans, target a Limited with the 1.8, under 90k miles, with documented oil-consumption test results and every oil change receipt.
✅ 2015 Kia Soul
A 2.0L '+' or '!' trim automatic with full recall documentation (SC124, SC141, SC160/162, SC200) completed and verified via NHTSA VIN lookup, ideally under 80k miles with maintenance records showing an early transmission fluid service.
