Kia Sportage MK4 (2016-2021) Performance
Kia Sportage MK4 Engine Performance
The fourth-generation (2016-2021) Kia Sportage offers a diverse range of engines. The 1.6 T-GDi petrol (174bhp) leads the petrol lineup, delivering sprightly performance and proving particularly capable in urban environments.
For those seeking better economy, the base 1.6 GDi (130bhp) provides adequate performance for daily use, though it can feel stretched when fully loaded.
Kia Sportage MK4 Diesel Performance & Power
The diesel range saw significant improvements during this generation. The initial 1.7 CRDi (114bhp) was replaced in 2018 by the more refined 1.6 CRDi, maintaining the same power output but offering better efficiency.
The 2.0 CRDi, available in both 134bhp and 182bhp variants, provides strong mid-range pulling power. Post-2018 models benefit from mild-hybrid technology, enhancing both performance and economy.
Kia Sportage MK4 Handling & Ride
The Sportage delivers composed and predictable handling for a family SUV. Its light and precise steering makes urban maneuvers straightforward. The optional all-wheel drive system provides additional confidence in challenging conditions.
Both manual and automatic transmissions perform well, with the 8-speed automatic (introduced in 2018) being particularly smooth and responsive.
Is The Kia Sportage MK4 Comfortable To Drive?
Ride quality is a strong point, especially compared to rival SUVs such as the Nissan Qashqai. The Sportage effectively absorbs road imperfections although it’s worth noting that GT-Line models with larger wheels trade some comfort for sharper looks and handling.
Refinement levels are good, with well-suppressed wind and road noise, though diesel engines can be heard when accelerating hard. The cabin remains composed at motorway speeds, making it a capable long-distance cruiser.

Kia Sportage MK4 (2016-2021) Reliability
Kia Sportage MK4 Reliability Ratings
The MK4 Sportage (2016-2021) earns trust through proven reliability data, particularly in post-2018 models which resolved earlier engine issues. It’s backed by a transferable 7-year warranty and strong safety credentials, including a 5-star Euro NCAP rating. High owner satisfaction scores, consistent resale values, and lower maintenance costs compared to premium rivals make it a dependable used SUV choice.
Kia Sportage MK4 Common Minor Issues
The MK4 Sportage boasts exceptional reliability in several core areas. The manual transmission proves virtually bulletproof with proper maintenance, while the basic chassis and suspension components rarely require attention. Interior build quality stands out, with robust seat mechanisms and climate control systems typically lasting the vehicle’s lifetime. Post-2018 models also show strong electrical system dependability, particularly power windows and central locking, a Kia hallmark. Most importantly, the basic engine block (excluding known Theta issues) and fuel system components demonstrate solid durability when properly maintained.

The key to MK4 Sportage longevity is timing – follow the service schedule religiously, particularly oil changes every 10,000 miles for turbocharged models and 20,000 for naturally aspirated engines. Don’t skip the DPF regeneration drives on diesels, and budget for preventative fluid changes rather than waiting for issues. These cars will easily surpass 150,000 miles when maintained properly.

Kia Sportage MK4 Model Reliability Comparison
The MK4 Sportage (2016-2021) sits in the middle of Kia’s reliability evolution. While more polished than the MK3’s simpler mechanics, it initially struggled with Theta engine issues. Post-2018 models showed significant improvement, though not quite matching the refined engineering of the current MK5. Within the Sportage lineage, MK4’s later years (2018-2021) represent peak reliability for the pre-hybrid era.

For optimal reliability in this generation, focus on 2018-2021 models, particularly the 1.7 CRDi diesel or 1.6 T-GDi petrol variants with comprehensive service records.
Kia Sportage MK4 Long-Term Reliability: High Mileage vs Low Mileage
The MK4 Sportage shows distinct reliability patterns across its mileage range. Under 60,000 miles, most examples remain trouble-free with just routine maintenance needed. The real test comes at higher mileages, particularly around the 100,000-mile mark. Pre-2018 models face potential Theta engine concerns at this point, while post-2018 variants demonstrate better durability when properly maintained.
Critical to high-mileage success is religious maintenance adherence, with regular oil changes and inspection of worn items like suspension components and brakes. Post-2018 models with a complete service history consistently show the best long-term durability, making them the preferred choice for buyers, especially hire purchase buyers, seeking high-mileage reliability.

Does The Kia Sportage MK4 Hold Its Value?
The MK4 Sportage shows respectable value retention, particularly in post-2018 models which typically retain 55-60% of their value after three years. Depreciation follows a predictable pattern, with a 20-25% drop in the first year, extending to 40-45% by year three, and reaching 50-55% by year five.
The best performers are 2018+ GT-Line diesel variants with comprehensive service history and reasonable mileage. This strong value retention is supported by Kia’s extensive dealer network (which spans London to Glasgow), transferable warranty coverage, and consistent demand in the used market. Compared to its generations, it holds value better than the MK3 but slightly trails the current MK5’s residuals.

Cheapest Kia Sportage Models To Maintain
The most economical MK4 Sportage models focus on simplicity and proven reliability. The naturally-aspirated 1.6 GDi petrol and post-2018 1.7 CRDi diesel in ‘2’ trim represents the most cost-effective choices, combining reasonable service costs with longer maintenance intervals.
Key Budget-Friendly Models:
- 1.6 GDi in ‘2’ trim (£150-200 annual maintenance).
- 2018+ 1.7 CRDi diesel (better fuel economy offsets service costs).
- Base models with fewer electronic features to maintain.
- Avoid pre-2018 turbocharged variants for lower running and maintenance costs.

Having tested hundreds of used Sportages, the 2018-2021 models stand out for their balance of durability and value. The 1.7 CRDi diesel or 1.6 T-GDi petrol engines prove most reliable, especially with documented maintenance. Just avoid pre-2018 models and ensure full service history.
Kia Sportage (2016-2021) Major Components Lifespan
The MK4 Kia Sportage demonstrates varying component lifespans based on maintenance and model year. Engines in pre-2018 models may experience issues around 100-120k miles, while post-2018 variants can reach 150-200k miles with proper care. Diesel models typically outlast gasoline engines. Transmission reliability ranges from 150-200k miles for manual transmissions to 120-150k miles for automatic versions, with early dual-clutch models being the most vulnerable.
Electrical systems generally prove robust, with infotainment lasting 8-10 years and power components remaining functional throughout the vehicle’s life. Batteries average 5-6 years, and start/stop systems may require attention around 60-80k miles.
The key to maximising the Kia Sportage’s longevity lies in consistent maintenance: regular oil changes, timely transmission fluid replacements, maintaining a full service history, and scheduling professional inspections. These practices can significantly extend the vehicle’s performance and reliability across all critical components.
Kia Sportage MK4 Most Expensive Common Repairs
The Kia Sportage MK4 (2016-2021) is well-regarded for its reliability, but like any used car with significant mileage, some owners have encountered expensive repairs.
One of the more common issues is clutch wear on manual models, sometimes needing replacement as early as 40,000 miles, with costs ranging from £800-1,200. Automatic versions with the DCT gearbox require regular fluid changes, skipping these can lead to faults that cost over £2,000 to fix.
There have also been a few reports of electrical issues which can rack up between £500-800 in repairs, but Kia’s generous warranty tends to negate the need for such an outlay.
Despite these potential costs, the Sportage remains a dependable SUV- similarly reliable to competitor offerings like the Ford Kuga and the VW Tiguan. Keeping up with servicing and driving it as intended can help avoid most major repairs.

My advice? Budget for maintenance and stick to the service schedule religiously. I’ve had my 2019 for over 100k miles with no major issues, but I’ve seen others rack up big bills by skipping services. These aren’t cars that forgive neglect.

Pros Include:
- Robust dashboard construction with minimal rattles.
- Hard-wearing seat materials that resist wear well.
- Good panel fit and finish throughout.
- Reliable electronics with few reported issues.

Kia Sportage MK4 Comfort Features
The Sportage prioritises practical comfort over luxury.
Key Features Include:
- Well-cushioned seats with good support.
- Spacious rear seating with reclining seatbacks.
- Effective climate control system.
- Good noise insulation, particularly in post-2018 models.
Kia Sportage MK4 (2016-2021) Boot Capacity:
- Standard: 491 liters.
- Mild Hybrid: 439 liters.
- Seats Folded: 1,480 liters.
Kia Sportage MK4 Suspension & Ride Quality Over Time
The Sportage’s suspension system shows good longevity with some characteristics:
Kia Sportage MK4 Early Signs Of Wear:
- Front struts typically need attention around 70,000-80,000 miles
- Rear suspension components generally last longer
- Original dampers may soften noticeably after 60,000 miles
Kia Sportage MK4 Long-Term Durability:
- The basic suspension design is robust
- Regular maintenance significantly extends component life
- GT-Line models with larger wheels may show earlier wear
- Most age-related issues are relatively inexpensive to fix

The Sportage’s suspension setup is a clever compromise between comfort and control. While not as sophisticated as some German rivals like Audi and VW, it manages everyday road imperfections admirably. The key is in its progressive damping – small bumps are absorbed well, though larger potholes can sometimes catch it out. GT-Line models with 19-inch wheels trade some comfort for style, so stick to the 17 or 18-inch wheels if ride comfort is a priority.
