Specs side by side
What owners say
Sonata
Overall
Sentiment is sharply divided by generation and powertrain, creating a high-risk, high-reward ownership profile. For models from approximately 2011-2019 equipped with the Theta II engine (particularly 2.0L and 2.4L variants), sentiment is overwhelmingly negative due to catastrophic, well-documented engine failures often occurring between 80,000 and 120,000 miles, leading to significant downtime, repair hassles, and loss of confidence. For the current generation (2020+), particularly hybrid models and those with newer "Smartstream" engines, sentiment shifts to positive, with owners praising superior value, advanced technology, quiet and comfortable highway ride, intuitive infotainment, and generous warranty coverage.
Best version to buy
For the current generation, the Sonata Hybrid Limited trim is frequently highlighted. Owners cite its comprehensive feature set, including a 360-degree camera, cooled seats, advanced highway driving assist (HDA), and a quiet, refined ride.
Known issues
- ⚠Catastrophic engine failure (Theta II engines, 2.0L, 2.4L): engines "grenade" or "blow" with little to no warning, often between 80,000-120,000 miles. Requires complete replacement. Frequency: very frequent for affected generations.
- ⚠Excessive oil consumption: engines "guzzle oil," particularly in models from around 2015, leading to potential engine damage if not monitored closely. Frequency: recurrent.
- ⚠Transmission failure: complete transmission replacement reported around 87,000-95,000 miles on some 2017-2018 models. Frequency: isolated.
Tucson
Overall
Sentiment is mixed and varies significantly by model year and powertrain. For the current generation (2022+), particularly hybrid and plug-in hybrid (PHEV) variants, owner feedback is generally positive, praising the quiet ride, comfortable interior, strong driver assistance features, and good value proposition. However, this is tempered by recurrent reports of significant electrical and powertrain issues, including dashboard/infotainment blackouts, 12-volt battery failures, and transmission problems leading to "limp mode." For the previous generation (approx. 2015-2021), feedback is more negative, citing reliability concerns, engine problems (including a specific mention of fuel injector failure on a 2022 model), and a general perception of lower long-term reliability compared to key Japanese competitors.
Best version to buy
Hybrid or Plug-in Hybrid (PHEV) trims, specifically the higher "Limited" or "Ultimate" trims. These are praised for their efficiency, quiet operation, and comprehensive feature sets.
Known issues
- ⚠**Current Generation (2022-2026):** * **Dashboard/Infotainment Blackouts:** Complete instrument cluster and center screen failures while driving at highway speeds. Dealers often cannot replicate, leaving issue unresolved.
- ⚠**Previous Generation (e.g., 2015-2021):** * **General Engine Reliability Concerns:** Mentions of oil consumption issues and catastrophic engine failure in high-mileage examples (e.g., 2016 model with ~200,000 miles).
- ⚠**Cross-Generation:** * **Dealership Experience:** Negative experiences with sales tactics (bait-and-switch on pricing) and service departments unable to diagnose intermittent issues. Frequency: recurrent.
