  • Catastrophic engine failure (Theta II 2.4L/2.0T) — Connecting rod bearing failure leading to seized engine, often around 100,000-150,000 miles; also severe oil consumption. Covered under a manufacturer settlement with extended warranty, but process is often lengthy. Frequency: very frequent.
  • Excessive oil consumption — Engine burns oil at a high rate, potentially leading to damage if not monitored closely. Frequency: recurrent.
  • Engine replacement process hardships — Long repair times (weeks to months), difficulties with dealer service departments, out-of-pocket costs for rental cars and misdiagnoses despite warranty coverage. Frequency: recurrent.
  • Stiff ride quality — Notably in 2020 models, described as firm and transmitting too much road feedback, a change from older, softer-riding sedans. Frequency: isolated.
  • Specific component failures — Power-folding mirrors and window motors failing. Frequency: isolated.
