The most frequently reported issues for the 2016 Chevrolet Impala cluster around the automatic transmission, electrical and infotainment systems, and occasional engine/performance concerns. While not every car experiences these problems, buyers and owners have documented a pattern of symptoms that are worth checking before purchase or during ownership.
Below is a detailed look at the categories of problems, typical symptoms to watch for, and practical steps to diagnose or address them if you’re evaluating a used 2016 Impala or dealing with one on the road today.
Transmission and Driveline
Transmission-related symptoms tend to appear as shifts that feel harsh, inconsistent, or delayed, and in some cases can lead to more serious driveline issues. The following are the commonly reported items under this category.
- Rough or abrupt shifts, especially when moving between gears or during acceleration
- hesitation to engage or slow responsiveness when pulling away from a stop
- Shuddering or surging during acceleration or at cruising speeds
- Occasional transmission slipping or failure in extreme cases
If you notice unusual shifting behavior, a diagnostic check of the transmission control module (TCM) and fluid condition is advised, as some issues can be resolved with software updates or fluid service, while others may require component replacement.
Electrical and Infotainment
Electrical glitches and infotainment problems are a common source of annoyance for 2016 Impala owners. Symptoms typically involve the MyLink system, instrument panels, and related electronics.
- Infotainment screen freezing, rebooting, or unresponsive touch input
- Bluetooth pairing dropouts or repeated connection issues with phones
- Digital gauges or warning lights displaying inconsistently or erratically
- Battery drain or intermittent electrical faults causing intermittent startup issues
These issues often originate from software quirks, wiring faults, or sensor glitches. Software updates, screen recalibration, or, in some cases, component replacement can address the problems. Regularly checking for GM service bulletins and recalls related to infotainment is advisable.
Engine and Performance
Engine and performance concerns vary by engine option and mileage. While many 2016 Impalas run smoothly, some owners report symptoms that affect acceleration, idle quality, or fuel efficiency.
- Occasional hesitation or misfiring affecting smooth acceleration
- Rough idle or fluctuating idle speed under certain conditions
- Lower-than-expected acceleration performance or sluggish response
- Auctioning for more fuel consumption than expected in real-world driving
These problems can stem from ignition and fuel delivery components, sensor inputs, or software calibrations. A thorough diagnostic scan can identify misfire codes, fuel trim anomalies, or sensor faults that can guide targeted fixes.
Brakes, Steering and Handling
Issues in the braking and steering realm can affect confidence on the road. The following problems have been reported by some owners.
- Brake pedal feel or braking performance that seems inconsistent or noisy
- ABS or traction control warning lights illuminating unexpectedly
- Steering assist problems, occasional stiffness, or unusual steering feedback
Investigations typically involve checking brake components (pads, rotors, sensors), brake fluid condition, and the power steering system. Software updates or component replacements may be recommended depending on the root cause.
Recalls, Safety and Warranty Considerations
Safety-related recalls and service campaigns can affect any used 2016 Impala. In addition to routine maintenance, verifying recall status is important for peace of mind.
- Takata airbag inflator recalls and related safety campaigns may affect some vehicles
- Other open recalls or campaigns tied to the transmission, electrical system, or safety components
Always check the vehicle’s VIN against the official recall database and consult a dealer about any outstanding recalls or required service campaigns. A clean recall status does not guarantee the absence of other non-safety reliability issues, but it is a critical baseline check.
What to Check When Buying a Used 2016 Impala
Prospective buyers should prioritize a comprehensive inspection that includes the transmission, electrical systems, and engine performance. Ask for maintenance records, a dealer diagnostic printout if available, and evidence of any software updates. If you already own a 2016 Impala, keep an eye out for the listed symptoms and schedule timely service to prevent potential failures from progressing.
Summary
The 2016 Impala is generally a spacious, comfortable sedan, but used examples can exhibit several recurring issues. Transmission behavior, infotainment and electrical glitches, engine performance variations, and braking/steering concerns are the most commonly reported areas. A diligent pre-purchase inspection, regular maintenance, and staying current with GM service notices can help mitigate surprises. As with any used car, the reliability of a particular vehicle will depend on its history, how well it was maintained, and how it was driven over its life.
