The Kia Sorento from the 2017 to 2020 model years delivers a versatile blend of comfort, technology, and practicality, making it a popular choice among midsize SUVs. While the Sorento offers a smooth ride, a spacious interior, and various engine choices, it is not without a few common issues. In this article, we’ll take an in-depth look at the most frequent problems owners encounter, as well as provide essential tips for prospective buyers and a breakdown of ownership costs.
Common Problems with the 2017-2020 Kia Sorento
1. Engine Oil Consumption and Potential Engine Failures
One of the more serious issues with certain Sorento models, especially those with the 2.4L 4-cylinder engine, is excessive oil consumption. Some owners report needing to add oil between regular oil changes, as the engine burns oil at a higher rate. If left unchecked, low oil levels can lead to severe engine damage, overheating, or even total engine failure.
Signs and Prevention: Keep an eye on the oil level regularly, especially between oil changes. Symptoms of low oil include a warning light on the dashboard, increased engine noise, or even smoke from the exhaust. Regularly monitoring oil levels and changing oil at recommended intervals can help, but ultimately, this may require more substantial intervention from a mechanic if consumption becomes severe. Kia has issued a recall on certain models for engine-related issues, so check if your vehicle is affected.
2. Transmission Issues and Harsh Shifting
The 6-speed automatic transmission in certain 2017-2020 Sorento models has been reported to exhibit problems such as delayed or rough shifting, especially as the vehicle ages. Some owners experience transmission jerking, shuddering, or even slipping out of gear, which can impact the vehicle’s overall drivability. These issues are often reported in both 4-cylinder and V6 models.
Signs and Prevention: During a test drive, pay attention to the transmission’s behavior during acceleration, deceleration, and at highway speeds. Look for any hesitation, unusual sounds, or rough shifts. Some owners have had success with transmission software updates or fluid changes, but in severe cases, a transmission rebuild or replacement may be necessary. If you’re purchasing a used Sorento, verify the transmission’s service history and look for any signs of repairs or updates.
3. Electrical System Problems and Malfunctioning Infotainment
Electrical issues, particularly with the infotainment system, are commonly reported in the 2017-2020 Sorento. Problems with the touchscreen freezing, unresponsive buttons, or Bluetooth connectivity issues are frequent frustrations for owners. Additionally, certain models have experienced issues with warning lights on the dash, such as the check engine light, due to minor electrical faults or sensor malfunctions.
Signs and Prevention: Test all electronic features, especially the infotainment system, Bluetooth, and dashboard indicators, to ensure they’re functioning correctly. Regular software updates can resolve some infotainment glitches, but persistent problems may require dealership intervention. If warning lights frequently appear, a thorough diagnostic check at a qualified mechanic is recommended.
4. Premature Brake Wear
Many owners of the 2017-2020 Sorento report that the brakes—particularly the brake pads and rotors—tend to wear out sooner than expected. This is a common issue with midsize SUVs as they carry more weight, putting added strain on the braking system. Premature brake wear can lead to increased stopping distances, vibrations, or grinding noises.
Signs and Prevention: Look for warning signs such as squeaking or grinding sounds when braking, as well as vibrations through the steering wheel or pedal. Regular brake inspections and timely pad replacements can help mitigate this issue. If buying a used Sorento, ask about the brake maintenance history, as frequent pad or rotor replacements may be needed throughout ownership.
5. Fuel Injector and Fuel System Problems
Fuel injectors in some Kia Sorento models, especially those with higher mileage, can become clogged or fail prematurely, leading to poor fuel economy, reduced engine power, and sometimes engine misfires. Fuel system issues can also result in the check engine light appearing on the dashboard.
Signs and Prevention: Symptoms of fuel injector problems include rough idling, difficulty starting, poor acceleration, or an increase in fuel consumption. Regular use of fuel injector cleaner additives can help keep the fuel system clean, and a professional inspection every 30,000 to 40,000 miles can identify any early signs of injector wear.
6. Suspension Wear and Bushing Problems
Suspension components, particularly the bushings, in the Sorento may wear out faster than expected, especially for those who frequently drive on rough roads or carry heavy loads. Worn bushings or suspension parts can result in a rougher ride, clunking noises, and poor handling, especially at higher speeds or on uneven surfaces.
Signs and Prevention: Listen for any rattling or clunking noises from the suspension during a test drive. Check for unusual tire wear patterns, as these can indicate suspension misalignment or bushing issues. Replacing worn suspension components can be costly, so verifying the condition of these parts in a used Sorento is essential.
7. Air Conditioning Compressor Failure
A relatively common problem in the 2017-2020 Sorento is the premature failure of the air conditioning compressor, especially in models used in hotter climates. When the compressor fails, the air conditioning system may blow warm air, reducing comfort in the cabin.
Signs and Prevention: When test-driving a Sorento, test the air conditioning to ensure it cools effectively. Any unusual sounds when the AC is running, like clicking or rattling, could indicate a problem with the compressor. Regular servicing of the AC system can prolong its life, though if the compressor fails entirely, replacement costs can be substantial.
Buying Tips: What to Look for in a 2017-2020 Kia Sorento
Service History: A full service history is essential, especially for engine and transmission maintenance. Look for records of oil changes, transmission fluid replacements, and any warranty or recall work that may have been performed.
Test for Transmission Smoothness: During a test drive, pay attention to how the transmission shifts. Hesitation, rough shifts, or unusual noises can indicate potential transmission issues.
Inspect Electronics and Infotainment: Make sure all electronics, including the infotainment and HVAC systems, are working properly. Testing Bluetooth connectivity and other infotainment features can reveal potential electrical issues.
Check for Signs of Brake and Suspension Wear: Examine the brake and suspension system, particularly if the vehicle has higher mileage. Any clunks, vibrations, or irregular tire wear patterns can suggest worn suspension or brake components.
Cost of Ownership: Is the 2017-2020 Kia Sorento Expensive to Own?
Fuel Economy
The Sorento’s fuel economy varies by engine type and drivetrain. The 4-cylinder engines are generally more fuel-efficient, but they also tend to struggle under heavy loads compared to the V6, which provides better towing and acceleration. While the fuel economy is average for an SUV in its class, owners may notice a decline in efficiency over time if fuel injectors or engine components start to wear.
Maintenance and Repair Costs
Routine maintenance, including oil changes, brake inspections, and transmission fluid changes, is typically manageable. However, some issues—such as premature brake wear, suspension repairs, or fuel injector cleaning—may increase maintenance costs. Transmission and engine repairs, if needed, can also be costly if they occur outside the warranty period. Fortunately, Kia’s warranty coverage (often up to 10 years or 100,000 miles for powertrain components) provides valuable peace of mind.
Insurance and Depreciation
The Kia Sorento has moderate insurance costs for an SUV of its size, and its resale value holds relatively well, especially for lower-mileage models with full-service records. Higher-trim models, which come equipped with features like leather seats and advanced safety technology, may hold their value better over time.
Potential Extra Costs
Replacing an air conditioning compressor, fuel injectors, or dealing with electrical issues could incur additional costs, especially if repairs occur outside the warranty. Regular preventative maintenance and attention to minor issues can help reduce the likelihood of these expensive repairs.
Conclusion
The 2017-2020 Kia Sorento is a solid, family-friendly SUV with a comfortable interior and ample space. However, it’s essential to be aware of common issues such as excessive oil consumption, transmission problems, and electronic glitches. By understanding these potential problems and staying diligent with maintenance, prospective and current owners can enjoy the Sorento’s benefits while minimizing unexpected repair costs.
