2011 Chevrolet HHR

The 2011 Chevrolet HHR (High Heritage Roof) is a retro-styled, compact wagon known for its spacious cargo area and distinctive design. Engine options included a 2.2L Ecotec inline-4 producing 155 horsepower and 150 lb-ft of torque, and a 2.4L Ecotec inline-4 generating 172 horsepower and 167 lb-ft of torque. Both engines could be paired with either a 5-speed manual or a 4-speed automatic transmission. Owners appreciate the HHR’s fuel efficiency, cargo capacity, and unique styling. However, common complaints include a somewhat cheap interior, road noise, and some reliability issues, especially in earlier model years.

Engine

2.2L Ecotec Inline-4

• Excessive Oil Consumption
  • Description/Symptoms: Some owners report higher-than-normal oil consumption, requiring frequent top-offs between oil changes. This can be due to worn piston rings or valve seals.
  • Solution: A compression test can help diagnose the cause. If rings are worn, an engine rebuild or replacement may be necessary. If valve seals are the culprit, they can be replaced.
  • Estimated Cost to Fix: $500 - $3000+ depending on the solution.
  • Recalls: None Found
• Timing Chain Issues
  • Description/Symptoms: Rattling noise upon startup, especially in colder weather. This may indicate a stretched timing chain or worn timing chain guides. If left unaddressed, it can lead to engine damage.
  • Solution: Replacement of the timing chain, sprockets, and guides.
  • Estimated Cost to Fix: $800 - $1500
  • Recalls: None Found

2.4L Ecotec Inline-4

• Excessive Oil Consumption
  • Description/Symptoms: Similar to the 2.2L, some 2.4L engines experience excessive oil consumption due to piston ring or valve seal wear.
  • Solution: Same as 2.2L, compression test, engine rebuild or replacement, or valve seal replacement.
  • Estimated Cost to Fix: $500 - $3000+ depending on the solution.
  • Recalls: None Found
• Timing Chain Issues
  • Description/Symptoms: Rattling noise upon startup, especially in colder weather. This may indicate a stretched timing chain or worn timing chain guides. If left unaddressed, it can lead to engine damage.
  • Solution: Replacement of the timing chain, sprockets, and guides.
  • Estimated Cost to Fix: $800 - $1500
  • Recalls: None Found

Transmission

4-Speed Automatic

• Harsh Shifting/Slipping
  • Description/Symptoms: Rough or delayed shifts, slipping between gears, or failure to shift properly. Can be caused by worn internal components, low fluid level, or a malfunctioning valve body.
  • Solution: Check fluid level and condition. If the fluid is dark or smells burnt, a transmission fluid flush and filter change may help. If the problem persists, a valve body replacement or transmission rebuild may be necessary.
  • Estimated Cost to Fix: $150 (fluid flush) - $3000+ (rebuild)
  • Recalls: None Found

Suspension

• Rear Suspension Sag
  • Description/Symptoms: The rear of the vehicle sits lower than normal, especially when loaded. This can be caused by worn-out rear coil springs.
  • Solution: Replacement of the rear coil springs.
  • Estimated Cost to Fix: $300 - $600
  • Recalls: None Found
• Clunking Noises
  • Description/Symptoms: Clunking sounds from the front or rear suspension, particularly when going over bumps. This can be caused by worn sway bar links, ball joints, or control arm bushings.
  • Solution: Inspection of suspension components and replacement of worn parts.
  • Estimated Cost to Fix: $100 - $500+ depending on the parts needing replacement.
  • Recalls: None Found

Electrical

• Power Window/Door Lock Issues
  • Description/Symptoms: Intermittent or complete failure of power windows or door locks. This can be caused by faulty window/door lock switches, wiring problems, or a failing door lock actuator.
  • Solution: Diagnose the specific problem and replace the faulty component.
  • Estimated Cost to Fix: $50 - $300+ depending on the component.
  • Recalls: None Found
• Instrument Panel Issues
  • Description/Symptoms: Gauges not working properly, dim display, or intermittent power loss to the instrument panel. This can be caused by a faulty instrument cluster or wiring issues.
  • Solution: Replacement of the instrument cluster or repair of damaged wiring.
  • Estimated Cost to Fix: $200 - $800+ depending on the solution.
  • Recalls: None Found

Exterior

• Door Hinge Issues
  • Description/Symptoms: Doors that sag, creak, or are difficult to close properly. This is often caused by worn door hinge pins and bushings.
  • Solution: Replacement of the door hinge pins and bushings.
  • Estimated Cost to Fix: $100 - $300 per door
  • Recalls: None Found

Interior

• Headliner Sagging
  • Description/Symptoms: The headliner detaches from the roof of the vehicle and begins to sag. This is more common in warmer climates.
  • Solution: Replacement of the headliner.
  • Estimated Cost to Fix: $200 - $500
  • Recalls: None Found
