Build my inspection planFrequently asked questions
Is the Hyundai Elantra reliable?
It's good value with a strong warranty; confirm any engine recall/software work and check oil use.
Do Elantras have engine problems?
Some engines have failure/stalling complaints — verify recall completion and history.
Is the Elantra a good used buy?
Yes, with recall history confirmed and clean oil-consumption records.
Does the 2017-2020 Hyundai Elantra use a timing belt or a timing chain?
The 2.0-litre Nu and the turbocharged engines fitted to this generation of Elantra all utilise a timing chain rather than a rubber timing belt. This chain is designed to last the lifetime of the vehicle, provided previous owners adhered to strict oil change intervals to prevent tensioner wear.
What should dealers look out for on Elantras equipped with the dual-clutch transmission?
The 7-speed dual-clutch gearbox, found primarily on Eco and Sport variants, requires careful assessment. It uses a dry clutch system prone to overheating and premature wear in heavy stop-start traffic. Dealers must check for software updates and ensure there is no excessive juddering or hesitation when pulling away.
What are the recommended service intervals for the 2017-2020 Hyundai Elantra?
For standard driving conditions, Hyundai recommends a minor service including an oil and filter change every 7,500 miles or 12 months. However, vehicles subjected to short urban journeys or heavy traffic fall under the severe usage schedule, requiring oil changes every 3,750 miles or six months to prevent premature wear.
