The 2016 Impala’s most frequently reported issues involve the transmission and driveline, electrical/electronic components, and engine performance, with some safety-related recalls affecting a portion of cars.
These concerns span several systems and can vary by mileage and maintenance history. This article summarizes the most commonly cited problem areas, describes typical symptoms, and offers guidance on diagnosis and recall checks using a vehicle’s VIN.
Transmission and driveline concerns
Owners have reported a range of transmission and driveline symptoms in the 2016 Impala, from shifting behavior to the feel of the powertrain during everyday driving.
- Harsh, delayed, or rough shifting in the six-speed automatic transmission
- Transmission shudder or vibration during deceleration or at low speeds
- Slipping gears or hard shifts, particularly when the engine is cold
- Intermittent engagement problems when shifting from park to drive or into reverse
If these symptoms occur, a skilled technician should inspect the transmission control module, fluid condition and level, and any related wiring or sensors. Some issues may be resolved with software updates or fluid service, but persistent problems can lead to more expensive repairs.
Engine performance and fuel system
Several common engine-related complaints focus on the 3.6-liter V6 and its supporting fuel/spark components.
- Misfires or rough running, especially under load or during acceleration
- Higher-than-expected oil consumption requiring more frequent top-offs
- Occasional stalling or hesitation, with the check engine light coming on in some cases
- Illumination of the service engine/maintenance required light due to ignition coils, fuel injectors, or sensor issues
These problems often involve ignition coils, spark plugs, fuel injectors, or sensors such as MAF/MAP. A thorough diagnosis (including a diagnostic scan, compression check if warranted, and inspection of ignition components) can determine whether the fix is simple maintenance, a component replacement, or a more involved repair.
Electrical and interior systems
Electrical glitches and infotainment reliability are among the more commonly reported interior concerns on the 2016 Impala.
- Infotainment system freezing, unresponsive touchscreens, or Bluetooth connectivity drops
- Instrument cluster flickering, dimming gauges, or intermittent display failure
- Power window regulator or motor failures causing slow or stuck windows
- HVAC blower motor or resistor failures affecting heating and cooling performance
- Keyless entry/remote start issues or weak battery in key fobs
Electrical problems may stem from wiring harness wear, body control module software, or common wear items like regulators and relays. Firmware updates or targeted component replacements are typical remedies.
Safety recalls and maintenance considerations
Safety-related recalls and service campaigns have affected some 2016 Impalas, so checking for open recalls by VIN is essential.
- Airbag inflator recalls (Takata and related safety campaigns) that cover many GM models, including the Impala
- Other safety recalls or service bulletins addressing transmission behavior, electrical glitches, or sensor reliability
- GM-issued software updates or service campaigns that address known driveline or electrical issues
If a recall applies to your vehicle, contact a Chevrolet dealer to schedule service and have recalls repaired at no cost. Use your VIN to verify current recall status on official sites or through GM customer service.
Buying and maintenance tips for a 2016 Impala
When evaluating a used 2016 Impala or maintaining one you own, consider these practical steps to minimize risk and prolong reliability.
- Check the vehicle’s VIN for open recalls on the NHTSA site or GM’s recall lookup tool
- Request a full service history, especially transmission service, oil changes, and any electrical work
- Have a qualified mechanic perform a pre-purchase inspection that focuses on the transmission, engine performance, and electrical system
- Test drive to reproduce any shifting, stalling, or infotainment issues and have the dealer or seller address them
Proactive maintenance, including timely transmission service, oil changes with the correct viscosity, and software updates when recommended, can help reduce the impact of these common problems.
Summary
The 2016 Chevrolet Impala has a few recurring trouble spots, most notably transmission behavior, engine performance with the V6, and electrical/infotainment reliability. Safety recalls are an important consideration, so verifying recall status by VIN is a wise first step in any purchase or ownership plan. With a thorough diagnostic approach and timely maintenance, many owners report satisfactory long-term reliability from the 2016 Impala.
