The Most Problematic HHR Model Years
While the Chevrolet HHR had a relatively short production run from 2006 to 2011, certain model years proved especially troublesome for owners. The 2006 complaints focused heavily on door handle failures and suspension problems, while the 2008 models experienced significant power steering shutdowns. Similar to BMW’s 2016 X1 issues, mechanical failures and safety warnings plagued certain HHR years. The vehicle ranked 63rd out of 80 in its class for reliability. RepairPal reports show the HHR generally has 0.3 unscheduled repairs annually.
The 2010 issues were particularly concerning, with widespread electrical system failures, faulty ignition lock cylinders, and problematic security systems. This model year also suffered from battery charging problems and multiple door handle breakages. A major safety recall in 2014 revealed that GM knew about dangerous ignition switch defects for years, affecting 1.6 million vehicles including the HHR and linking to multiple fatalities.
Common Mechanical Issues to Watch For
Beyond the model-specific issues, the HHR exhibits several mechanical problems that owners should monitor carefully. Engine performance issues commonly arise from clogged air filters, damaged intake hoses, and faulty fuel injectors, leading to rough running and power loss. The VVT solenoid valves can fail, causing rough engine operation and potential stalling when oil pressure isn’t properly regulated. The electronic power steering system frequently fails, particularly after incorrect jump-starts that blow the 60-amp fuse, resulting in heavy steering and reduced assist.
Watch for throttle body failures, which cause rough idle and engine hesitation. These issues often require professional cleaning or complete replacement. Additionally, loose or worn gas caps trigger check engine lights and emissions problems. The vehicle’s security system can also malfunction, causing unexpected door locking and requiring module replacement or software updates to resolve.
Transmission Problems and Warning Signs
Throughout the HHR’s production run, transmission issues have plagued specific model years, with the 2008 redesign showing particularly concerning problems. Watch for transmission slipping, hollow noises, and burnt fluid incidents that often indicate impending failure. Warning signs include erratic “Traction Control off” lights and abnormally high engine revving while in gear. Service centers often struggle to diagnose these transmission-related symptoms correctly. Like the continuous variable transmission system in Nissan Rogues, HHR transmissions are prone to early failure and costly repairs.
Similar to the transmission failures reported in Chevy Malibu models between 2008-2013, the control module system presents additional complications, as electrical glitches can trigger transmission faults and warning lights. You’ll need to monitor both mechanical and electronic systems closely. Repair costs average $3,000 for major transmission work, typically occurring around 47,100 miles in 2008 models. Common failure points include transmission solenoids, torque converters, and shift interlock mechanisms. If you notice irregular shifting patterns or fluid leaks, have your vehicle inspected immediately.
Electrical System Defects by Year
The electrical system defects in Chevrolet HHR models represent some of the vehicle’s most problematic issues, particularly in model years 2006-2011. You’ll find the 2006 model plagued by wiring problems and fuse issues that cause no-start conditions. The 2007 model shows increased instances of “run then no start” behavior due to relay overheating, while the 2008 model was significantly affected by the infamous ignition switch recall. Many owners report cruise control malfunctions when tail lights burn out.
Electrical failures become more frequent as these vehicles age, especially after 100,000 miles. You’ll need to watch for symptoms like headlight outages, air conditioning failures, and blown fuses. Diagnosis often requires specialized tools and manufacturer software, with repair costs averaging between $122 and $179 for electrical system diagnostics.
Safety Concerns and Recall History
Safety concerns plagued Chevrolet HHR models from 2006-2011, with multiple major recalls affecting over 500,000 vehicles. The most severe issue was the defective ignition switch that could shut off while driving, disabling critical systems including airbags and power steering. GM’s recall impact extended to establishing a $400 million compensation fund for victims. The issue was particularly dangerous as heavy key chains could trigger unexpected shutdowns. Much like the engine troubles seen in early Buick Encores, these defects posed serious safety risks.
You’ll want to be particularly cautious of 2006-2008 models, which faced additional recalls for interior impact protection issues involving faulty storage bin latches. Similar to the first-generation Vue issues, electrical problems were a common complaint. The 2009-2010 non-turbo models experienced electric power steering failures, requiring complete motor replacements. These safety ratings were further compromised by the risk of airbag non-deployment due to the ignition switch defect, making affected models potentially dangerous in crash scenarios.
Long-Term Ownership Experiences
While many HHR owners have achieved impressive mileage counts exceeding 200,000 miles, long-term reliability proves inconsistent across model years. Similar to the engine problems plaguing the 2013 Elantra, mechanical issues can surface unexpectedly. You’ll find annual maintenance costs averaging $540, which is relatively moderate, but persistent minor issues often escalate into major repairs as these vehicles age. Professional mechanics strongly recommend maintaining a prayer card holder given the vehicle’s reputation for unpredictable breakdowns. Like the Impala’s passlock system failures, electrical problems can lead to frustrating starting issues and battery drain.
Owner satisfaction varies greatly, with long-term durability depending heavily on maintenance practices. While some report minimal unscheduled repairs, others face recurring problems with electrical systems, transmission failures, and suspension wear requiring replacement around 60,000 miles. The 2010 model year particularly stands out for its numerous issues, including cam sensor failures, broken door handles, and persistent dashboard malfunctions. Despite practical features like fold-flat seating and ample cargo space, mechanical reliability concerns ultimately impact the HHR’s viability as a long-term investment.
Maintenance Costs and Reliability Ratings
Looking beyond long-term ownership experiences, maintenance costs and reliability ratings paint a clearer picture of the HHR’s value proposition. You’ll find the HHR scores a solid 4.0/5 on RepairPal’s reliability scale, ranking 13th among 36 compact cars. Maintenance trends show annual costs averaging $540, which falls below the industry standard of $650.
When examining reliability comparisons, the HHR demonstrates fewer unscheduled repairs at 0.3 per year versus the 0.4 industry average. The vehicle also shows a 10% probability of severe issues, performing better than both subcompact and overall vehicle averages. However, you’ll need to budget for specific maintenance items like front suspension replacements at 60,000 miles and factor in potentially complex repairs, such as headlight bulb replacements that require partial vehicle disassembly. Some owners have reported achieving perfect performance at 200,000 miles with proper maintenance routines.
Design Flaws and Known Weaknesses
Despite its attractive retro styling, the Chevrolet HHR exhibits several notable design flaws that you’ll want to contemplate. User complaints highlight serious security door lock system vulnerabilities, with doors unexpectedly locking while driving and warning lights activating without cause. The electronic power steering system‘s susceptibility to jump-start damage poses significant concerns, while throttle body design vulnerabilities lead to performance issues and frequent replacements.
