Summary Verdict

The 2011 Chevrolet HHR, while offering a unique style and practicality, shows some common reliability concerns as it ages. The 2.4L engine is more prone to oil consumption and timing chain issues than the smaller 1.8L. The automatic transmission can experience slipping or control module problems. Suspension components like struts and ball joints are typical wear items that may require attention. Electrical issues, particularly with power windows and sensors, are also noted. Exterior rust can be a concern in certain climates, and interior elements like the dashboard may develop cracks. Overall, while not plagued by widespread catastrophic failures, owners should be aware of these potential repair areas and budget accordingly for maintenance and repairs.
