What are the common problems in a 2017 Chevy Sonic?
The most frequently reported issues for the 2017 Sonic involve the drivetrain and electronics: transmission hesitation or shifting problems, engine misfires or rough idle, and electrical or power steering faults, with typical wear items like brakes and suspension showing up as mileage climbs.
Drivetrain and transmission
Below are the issues owners most commonly report related to the Sonic’s drivetrain and transmission, based on consumer feedback and service histories.
- Transmission shifting problems: Some drivers report harsh, delayed, or slipping shifts with the available 6‑speed automatic or manual transmissions, sometimes requiring software updates or transmission service.
- Harsh or intermittent shifting/torque converter concerns: Occasional shuddering or feel of the transmission not engaging smoothly, which can lead to further wear if left unaddressed.
- Engine performance affecting transmission response: Misfires or reduced power can make shifts feel less smooth, especially on turbocharged variants.
- Oil consumption questions: A number of owners report higher than expected oil use, necessitating more frequent top-offs and, in some cases, repairs to seals or related components.
Maintenance and timely inspection are commonly advised to address drivetrain notes before they progress into more expensive repairs.
Notes on fixes and maintenance
Dealership software updates, torque converter servicing, and ignition/fuel system checks are typical first steps when facing these symptoms. A qualified technician can diagnose transmission fault codes and inspect related sensors to determine whether a repair or replacement is needed.
Engine and performance
Engine-related concerns are frequently cited by Sonic owners, particularly around misfires and idle quality, as well as turbo-related power delivery in turbocharged models.
- Engine misfires and rough idle: Misfires or rough idling can occur, often linked to ignition coils, spark plugs, or fuel injectors in some engines.
- Turbo-related power or boost irregularities: In the turbocharged 1.4L variant, some drivers report inconsistent boost or power delivery, sometimes tied to sensor or wastegate issues.
- Stalling or hard starting (sporadic): In a subset of vehicles, the engine may stall or fail to start, sometimes associated with sensor faults or fuel delivery concerns.
- Oil consumption and gasket concerns: A subset of owners notes faster oil loss or minor leakage that requires monitoring and potential gasket-related repairs.
Owners and technicians emphasize the importance of using the correct oil specification and performing timely spark/fuel system maintenance to preserve engine reliability.
What to watch for
Pay attention to engine warning lights, rough running, or unusual sounds, as these can indicate ignition, fuel, or sensor issues. Regular maintenance and prompt diagnosis can prevent more serious failures down the line.
Electrical systems and infotainment
Electronic components and dashboards are a common source of complaints, spanning infotainment to steering and charging systems.
- Infotainment and electronics glitches: Touchscreen freezes, Bluetooth disconnects, or system resets are among the most reported electronic issues.
- Power steering/electric assist faults: Some Sonic owners experience sudden loss of power steering assist or warning messages, requiring module software updates or component replacement.
- Battery, charging, and alternator concerns: Early battery failures or charging inconsistencies can appear, especially with aged units or vehicles with high electrical load from accessories.
Electronic systems can be sensitive to temperature and wear, making preventative software updates and connector inspections worthwhile as part of routine maintenance.
Infotainment and electrical reliability tips
Check for software updates at a GM dealer, inspect fuses and connectors for corrosion or looseness, and monitor battery health. If warning lights appear, a diagnostic scan can prevent ambiguous repairs and guide proper fixes.
Brakes, suspension, and handling
Suspension wear and braking quality are commonly reported as mileage increases, affecting comfort and safety.
- Brake wear and rotor issues: Owners may notice noise, vibrations, or reduced stopping power due to wear; pads, rotors, and occasionally caliper components may need service.
- Wheel bearings and CV joints: Some cars exhibit rumbling noises or play in the front wheels, often traced to wheel bearings or CV joints.
- Steering and alignment concerns: While less common, there are reports of steering feel changes or alignment drift over time requiring service.
Routine inspections of brakes, tires, and suspension components can help ensure safety and ride quality as mileage climbs.
Maintenance and prevention considerations
Regular brake inspections, tire rotation, and proactive suspension checks are recommended. Addressing issues early can prevent more costly repairs and keep handling predictable.
Recalls, service history, and verification tips
With the Sonic, as with most vehicles from a major manufacturer, certain units are subject to recalls or service campaigns. Always verify your specific VIN against official recall databases and GM’s service advisories.
- Recall checks: There have been recalls affecting some 2017 Sonic models, including items related to power steering and airbags in some regions.
- VIN-specific history: Use the VIN to review recall status, open campaigns, and prior repairs. A complete service history helps assess current reliability and future risk.
For peace of mind, consult a dealer or a trusted service provider to review recall statuses and necessary repairs tied to your vehicle’s history.
Summary
The 2017 Chevy Sonic shows a pattern of common problems centered on the drivetrain, engine performance, and electrical systems, with brakes and suspension wear appearing as miles accrue. While not every vehicle experiences these issues, owners who keep up with routine maintenance, act on recalls, and pursue timely diagnostics tend to report better reliability. If you’re considering a used 2017 Sonic, obtain a full service history, check for open recalls, and have a trusted technician perform a pre-purchase inspection to assess the condition of the transmission, engine, electrical systems, and safety components.
