Ford Fusion vs Hyundai Sonata: Reliability Compared

Ford Fusion

Hyundai Sonata
Reliability is effectively tied between the Hyundai Sonata and Ford Fusion. Fusion owners file far more complaints per car sold; Sonata has more recalls. The deciding factor is the type of failure: Fusion engines can need replacement, while Sonata problems are scattered across injectors, power loss and batteries.
How Do the Ford Fusion and Hyundai Sonata Generations Compare?
Verdict
The Ford Fusion is more reliable than the Hyundai Sonata, scoring 69/100 vs 68/100.
Reliability is effectively tied. Both cars hold a good standing, and each has a different weak spot. The Fusion draws far more owner complaints for every car sold, and its cracked flex plates and coolant-in-cylinder failures often end in a new engine. The Sonata has more recalls and a wider spread of complaints, from injectors to lost drive power. Neither car pulls clearly ahead, so the model year and the engine matter more than the badge.

What Are the Common Problems With the Ford Fusion and Hyundai Sonata?
Engine damage with a costly fix defines the Fusion, while the Sonata's trouble is scattered. A cracked flex plate rattles at idle with no warning light, and coolant leaking into the cylinders can mean a full engine replacement. Sonata owners report injectors that fail and return, sudden loss of drive power, and dead 12-volt batteries on the hybrid. Crash-linked reports are heavier on the Sonata's power train. Only the Fusion has crash-linked steering complaints, where front lower control arms snapped and two cars hit a utility pole. Only the Sonata has crash-linked engine and lighting complaints.

Who Should Buy the Ford Fusion vs the Hyundai Sonata?
Ford Fusion vs Hyundai Sonata: Common Questions
- Is the Hyundai Sonata more reliable than the Ford Fusion?
- No clear winner. Both hold a good standing and the comparison comes out effectively tied. The Sonata has fewer complaints per car sold, but it carries more recalls and a broader mix of problems. The Fusion's complaints are concentrated in engine and flex plate failures that can be expensive.
- Which has more recalls, the Sonata or the Fusion?
- The Sonata has more. Federal recall records show 20 recalls across 9 Sonata model years. The Fusion has 8 across 3 model years. The Fusion's data covers only 2018 to 2020, so the two counts span different lengths of time.
- Which Fusion model years should I avoid?
- Avoid 2018, which is listed among the weakest years. The 2019 year appears in both the strongest and weakest lists, so inspect any 2019 closely. The 2020 car ranks strongest, but check for flex plate noise and coolant loss on any Fusion with the 1.5L EcoBoost.
- What is the cracked flex plate problem on the Ford Fusion?
- It is the most common Fusion power train failure in owner complaints. It shows up as rattling or knocking at idle that gets louder with the air conditioning on, often with no warning light. Reports run from about 40,000 to 91,000 miles, and dealers often replace the torque converter and transmission pump too.
- What goes wrong most often on the Hyundai Sonata?
- Engine complaints lead, with fuel injectors that fail and come back, causing jerking, power loss and poor fuel economy. Electrical problems follow, mainly dead 12-volt batteries on the hybrid. Power train reports describe sudden loss of drive power, and that area has the most crash-linked complaints.
