Hyundai Repair & Service in Cedar Rapids
Theta II engine experts — from routine maintenance to complex repairs.
Expert Hyundai Repair in Cedar Rapids
Hyundai vehicles have earned a reputation for value and reliability, but like any brand, they have their weak spots. Whether you drive an Elantra, Tucson, Santa Fe, Sonata, Kona, or Palisade, Cedar Automotive has the experience and equipment to keep your Hyundai running at its best. We handle routine maintenance, complex engine work, and everything in between.
Hyundai's Theta II engine family — the 2.0L and 2.4L found in Sonata, Santa Fe, and Tucson — has well-documented issues with engine bearing failure and excessive oil consumption. Our technicians are experienced in diagnosing these problems early, before a minor knock turns into a seized engine. We also understand the nuances of Hyundai's dual-clutch transmission (DCT), which requires specialized service procedures that many general shops overlook.
From the compact Kona to the full-size Palisade, every Hyundai model gets the same thorough attention. We use professional-grade diagnostic equipment to access Hyundai-specific fault codes and live data — giving you accurate diagnoses without the dealership price tag. Located in Cedar Rapids near the regional airport, we offer same-day service for most appointments.

Common Hyundai Issues We Diagnose and Repair
Theta II 2.0T / 2.4 Rod Bearing
2011–2019 Hyundai Sonata, Santa Fe, and Tucson with the 2.0T and 2.4L Theta II engine are subject to rod bearing failure that often triggers the Hyundai engine recall. A knock under load is the warning. We perform the factory knock sensor test, document results, and help owners pursue Hyundai warranty coverage when the test qualifies.
Crankshaft Position Sensor Stall
Hyundai Sonata, Elantra, and Santa Fe develop crankshaft position sensor failures that cause intermittent stalls and no-start conditions after the engine is warm. We confirm with live-data scanning during the stall event, replace the sensor with a Hyundai OE unit, and verify no subsequent fault codes before returning the vehicle.
GDI Carbon Buildup
Hyundai GDI engines build carbon on the intake valves because fuel never washes over them. Rough idle, misfires, and reduced fuel economy are the symptoms. We walnut-blast the intake valves, replace the intake manifold gaskets, and reset long-term fuel trims so the engine breathes like it did new. Carbon cleaning is recommended every 80,000–100,000 miles.
Oil Consumption (Theta II)
Theta II 2.4L engines commonly consume oil at over a quart per thousand miles. Hyundai's Knock Sensor Detection System can pre-emptively flag engines at risk. We run the factory oil consumption test, document results, and help owners pursue Hyundai extended warranty coverage when eligible. Cases that fall outside coverage get an honest repair quote.
Steering Coupler Clunk (Sonata / Elantra)
Hyundai Sonata, Elantra, and Elantra GT steering couplers develop a clunk over bumps or from lock to lock. We replace the intermediate shaft coupler with the updated Hyundai revision part and verify smooth, quiet steering on the road test. Left unrepaired, it wears other front-end components prematurely.
ABS / HECU Module Failure
Some 2006–2011 Hyundai Sonata and Santa Fe HECU (ABS) modules fail internally, throwing ABS, TCS, and airbag lights simultaneously. We diagnose with Hyundai GDS scan data, repair or replace the HECU with a compatible programmed unit, and perform the required brake bleed and sensor calibration afterward.

Frequently Asked Questions
Can Cedar Automotive evaluate my Hyundai for the Theta II engine recall?
Yes. The 2.0T and 2.4L Theta II engine recall affects 2011–2019 Sonata, Santa Fe, and Tucson. We perform the factory knock sensor test, document the results in writing, and help you pursue Hyundai warranty coverage when the test qualifies. Having documented diagnostic evidence from an independent shop strengthens the claim. Call Cedar Automotive at (319) 450-7584 to schedule.
Do you diagnose Hyundai crankshaft position sensor stalls?
Absolutely. Hyundai Sonata, Elantra, and Santa Fe crank sensor failures cause intermittent hot-engine stalls that disappear by the time the tow truck arrives. We confirm the failure with live data during a stall event, replace the sensor with a Hyundai OE part, and verify no subsequent fault codes before handing the car back.
Can you clean carbon off Hyundai GDI engine intake valves?
Yes. Hyundai GDI engines develop carbon on the intake valves because fuel never touches them. Symptoms are rough idle, misfires, and reduced fuel economy. We walnut-blast the intake ports, replace the intake manifold gaskets, and reset long-term fuel trims. Recommended every 80,000–100,000 miles to keep the engine running smoothly.
Do you program Hyundai keys and fobs?
Yes — we cut and program Hyundai keys, smart keys, and proximity fobs for Sonata, Elantra, Santa Fe, Tucson, and Palisade at independent-shop pricing. Cedar Automotive carries dealer-level Hyundai GDS access in-house. Call (319) 450-7584 so we can verify your Hyundai model year and security type before making the trip in.
