After helping 1,300,000 drivers across the U.S. manage repairs and maintenance, we’ve learned that the top Hyundai issues are engine bearing knock, excessive oil consumption, 7‑speed Dual‑Clutch Transmission (DCT) shudder, Anti-Lock Braking System module short/battery drain and hard-starts caused by evaporative emissions (EVAP) purge valve faults.
Hyundai addressed many engine knock concerns under extended coverage, so check before paying out of pocket. Track oil consumption and keep maintenance records, as Hyundai sometimes offers help when service history is well-documented.

Pro tip: If you’re shopping, Jerry customers have learned that documented diagnosis or quotes for these items can be fair negotiation leverage.
Quick checks for the top issues above (no special tools)
Engine develops a rhythmic knocking that rises with RPM:
With engine cold, start and listen near wheel wells. A deep, steady knock that increases with revs is a red flag—shut it down.
Car shudders and hesitates from a stop with a DCT:
On a flat surface, gentle launch; feel for repeated shudder or delayed engagement without wheel spin.
ABS and brake lights come on and battery drains when parked:
Note warning lights, warm ABS module area after sitting or a weak battery after overnight parking.
Long crank or rough start immediately after refueling:
After a fuel stop, if cranking is long or stumbles, try starting with the pedal slightly pressed—then suspect the purge valve.
Steering wheel clicks or feels loose on-center at low speed:
In a parking lot, turn the wheel slowly left/right; feel for a soft click or notchiness around center.
Maintenance that reduces risk for these issues
Change oil and filter every 5,000–6,000 miles on GDI/turbo engines; use the correct spec and replace the PCV valve around 60,000 miles to help curb consumption and deposits.
Refresh coolant every 5 years/100,000 miles to maintain proper chemistry and protect the water pump.
Install spark plugs every 60,000–90,000 miles (turbo toward the low end); a smooth idle reduces DCT lugging.
Flush brake fluid every three years to keep ABS valving healthy and keep corrosion down.
Don’t top off the tank after the first click; it protects the EVAP system.
If your car’s maintenance history is unknown, baseline at 60k/90k checkpoints and bundle labor where possible (e.g., plugs with coil inspection, A/C service with belt inspection). You can set these benchmarks by keeping your maintenance records current in the Jerry app.
When to stop driving to avoid bigger bills
If you’re unsure whether it’s safe, pull over and call a mechanic or tow. New warning lights, severe new noises or smells, or fluids pouring out are all ‘stop now’ signals. Here are common situations where stopping immediately is the right move:
Temperature warning or clear signs of overheating.
Flashing Check Engine Light with power loss or heavy misfire.
Brake warning lights or a suddenly soft/long pedal.
Sudden rhythmic knocking even with the oil light off–stop immediately.
If you’re using the Jerry app, you can run a quick triage in Diagnose before you tow, then compare price ranges at a local shop for the likely repair.
When I disassembled the column and removed the motor, there it was—the rubberized steering coupler insert, which absorbs the harsh movements of the powerful electronic motor, had disintegrated.
The fix included a $10 part and about 2 hours of labor. The total bill was just under $250 and the customer was relieved the problem wasn’t something like the steering rack or loose suspension part. Don’t panic when you hear a clicking or clunking noise behind the steering wheel of your Hyundai—it may just be a simple coupler replacement.

My oil level drops between changes—should I use a thicker oil?

Will an EVAP code make me fail emissions?
-
Am I overpaying for a Sonata engine replacement?
-
Do I need OEM Hyundai parts or can I use aftermarket?
-
Can software updates really fix DCT shudder?
