The handles are made of brittle plastic that becomes fragile with age and temperature cy… Repairs typically run $20-$200. Severity: medium.

What is the 2006-2011 Chevrolet HHR Passlock Anti-Theft System No-Start (Security Light)?

What is the 2006-2011 Chevrolet HHR Blower Motor Resistor Failure / Cowl Water Leak (HVAC Only Works on High)?

A very common HHR HVAC fault: the blower fan stops working on low and medium speeds and only runs on High (which bypasses the resistor). The root cause is a failed blower motor resistor, frequently accelerated by a design flaw where the butyl sealant patch under the passenger-sid… Repairs typically run $50-$250. Severity: low.

What is the 2006-2011 Chevrolet HHR Inaccurate / Fluctuating Fuel Gauge (Fuel Level Sensor)?

HHR owners frequently report the fuel gauge reading incorrectly or bouncing around unpredictably while driving, sometimes stuck on empty or full.
