Hyundai Service Questions, Answered
What paperwork do I need for a Hyundai warranty repair?+
Keep a digital or physical copy of your Sonny's invoice, which is your repair order. Show it when you bring your Hyundai back for warranty service, and it shows what was repaired and when. Beyond 25 miles from our shop, call the warranty administrator before any repair begins. See our warranty terms and conditions for full details.
Should I check the oil in my Hyundai between changes?+
Yes. Direct-injection four-cylinders like the 2.0L and 2.4L in the Sonata, Tucson and Santa Fe often use some oil between changes, and running low is a common cause of a knock from the bottom of the engine and the oil pressure light. Check the dipstick monthly and top off before long drives.
Will you tell me what my Hyundai needs before any work starts?+
Yes. We diagnose first, then send a written quote, and work begins only after you approve it in writing. Anything extra we find along the way is reported to you first, never fixed without your approval. Booking online takes about 60 seconds.
Do you accept extended warranties on Hyundai repairs?+
Have an extended warranty or service contract? We work with most major providers. Tell us about your contract when you book your Hyundai, and we get written authorization from your provider before repairs begin. See how extended warranty claims work.
