Barnes Auto Service handles Hyundai repair in Louisville, and one of the first questions owners ask us is whether their engine is part of the Theta II settlement. For certain 2011 to 2019 Sonata, Santa Fe Sport, and Tucson models, the answer matters. We also handle dual-clutch hesitation on turbocharged trims and SmartSense calibration after windshield work.
We work on the Elantra, Sonata, Tucson, Santa Fe, Palisade, Kona, and Venue, along with Hyundai hybrid and electric models. Three ASE Master Technicians lead our team.
How Hyundai BalancesPerformance and Efficiency
Hyundai packs a lot of tech into every model. Some of it needs more attention than the rest.
- Theta II 2.0L and 2.4L GDI engines: Certain 2011 to 2019 Sonata, Santa Fe Sport, and Tucson models are covered by a settlement for connecting rod bearing failure. Knocking, low oil, or an oil pressure warning on one of these engines is never something to put off.
- 1.6L turbo with a 7-speed DCT: This pairing shows up in the Elantra Sport and N Line, the 2016 to 2021 Tucson, and the Kona. The turbo needs clean oil, and the dual-clutch transmission can feel hesitant at low speed.
- Intelligent Variable Transmission (IVT): Hyundai’s version of a CVT is used in most non-turbo Elantra, Kona, and Venue models. Smooth and efficient, it depends on the correct fluid.
- SmartSense: Lane keeping, forward collision avoidance, and smart cruise all rely on a camera and radar that need recalibration after windshield replacement or certain suspension repairs.
- Hybrid and electric: The Tucson, Santa Fe, and Sonata come in hybrid or plug-in hybrid versions. The Ioniq 5, Ioniq 6, and Kona Electric are fully electric.
How to Tell Your Hyundai Needs a Visit
Engine and transmission
- A knock or tick that gets louder as the engine warms up
- An oil pressure light, or oil running low between changes
- Jerky, hesitant takeoffs on a DCT model
- A check engine light, flashing or steady
Everything else
- A SmartSense message or lane keeping that stops working
- Brakes that pulse or grind
- A/C that can’t keep up in July
- Drips or puddles where you park

Hyundai Maintenance and Repair, Handled Start to Finish
Engine and transmission concerns top the list for most Hyundai owners, so that’s where we’ll start.
Engine Repair and Replacement
Theta II knock and bearing concerns, turbocharger problems, misfires, and oil leaks all get a careful diagnosis. When an engine needs to be replaced, we use quality parts.
Oil Changes and Preventive Maintenance
Clean oil may be the single best thing you can do for a Theta II or turbocharged engine. Along with oil changes in the grade your Hyundai calls for, we handle DCT and IVT fluid, coolant, spark plugs, filters, and BG fluid services.
Diagnostics and SmartSense Calibration
Our technicians scan for codes, review live data, and perform ADAS calibration on SmartSense cameras and radar after qualifying repairs. Charging faults and module concerns get traced the same way.
Hybrid and EV Service
Battery systems, charging components, and electric motor concerns on Hyundai hybrids, plug-in hybrids, and EVs are all within our scope.
Brakes and the Electronic Parking Brake
Many newer Hyundai models have an electronic parking brake that has to be put in service mode, often with a scan tool, before rear brake work. It’s a small step, and skipping it can damage the caliper.
Suspension and Steering
Struts, mounts, control arm bushings, and sway bar links wear with time and Louisville potholes. Pinpointing the right one keeps the repair bill honest.
Tires and AWD Care
On AWD models like the Tucson, Santa Fe, and Palisade, tread depth should stay matched across all four tires to protect the AWD system. We sell and install tires and handle rotation, balancing, flat repair, and TPMS service.
A/C and Heat Repair
When one side of a dual-zone system stops responding, the cause can be a blend door actuator or the controls rather than the refrigerant. We check those along with the compressor, condenser, evaporator, and charge.
Pre-Purchase Inspections for Used Hyundai Buyers
For a used Sonata or Santa Fe Sport, engine knock and oil pressure history come first. We also road test the transmission and check suspension, brakes, and tires.

FAQs About Hyundai Repair in Louisville
Is my Hyundai covered by the Theta II engine settlement?
Coverage depends on your model, year, and engine, but certain 2011 to 2019 Sonata, Santa Fe Sport, and Tucson models with 2.0L or 2.4L Theta II engines were included in the settlement. Hyundai’s owner resources can confirm coverage using your VIN.
Why does my Hyundai hesitate when accelerating from a stop?
Hesitation from a stop is common on Hyundai models with a dual-clutch transmission, and it usually traces to clutch wear, software calibration, or fluid condition. A road test and scan help narrow down which one it is.
Is the Hyundai Ioniq 5 a hybrid or electric?
The Ioniq 5 is fully electric, with no gas engine, and it charges from a home charger or a public charging station. Hyundai’s hybrid lineup includes the Tucson Hybrid, Santa Fe Hybrid, and Sonata Hybrid.
What does SmartSense calibration fix?
SmartSense calibration realigns the camera and radar so lane keeping, forward collision avoidance, and smart cruise control work correctly. It’s typically needed after windshield replacement or alignment-related repairs that change how the sensors point at the road. A quick check afterward confirms each feature works.
