2017 Chevrolet Impala
Vehicle Specs & Maintenance Data
The 2017 Chevrolet Impala maintenance specs on this page cover the key fluids, torque values, and wear items you need for routine service. Use these numbers as a quick reference when performing oil changes, tire rotations, brake jobs, and other scheduled maintenance on your Chevrolet Impala.
For oil changes, the 2017 Chevrolet Impala takes 5W-30 Full Synthetic motor oil with a capacity of 5 quarts. Brake fluid type is DOT 3, the recommended coolant is Dex-Cool (OAT), and transmission fluid is Dexron VI. Always use the manufacturer-recommended fluids to maintain warranty coverage and engine longevity.
When mounting wheels on the Chevrolet Impala, torque the lug nuts to 110 ft-lbs using a calibrated torque wrench. Over- or under-torquing can lead to warped brake rotors or loose wheels. Re-torque after 50 to 100 miles on newly installed wheels.

6-Speed Transmission Harsh Shifting and Torque Converter Shudder
The 6T70/6T75 six-speed automatic transmission in the 2018 Impala develops harsh shifting, delayed engagement, and a shudder during light acceleration at 30-50 mph. The shudder originates from the torque converter clutch and feels like driving over a washboard road. This is a well-documented issue across multiple GM models using this transmission family.
Perform a transmission fluid flush using Dexron HP ATF as a first step. If the shudder persists, the torque converter must be replaced. Reference GM TSB 18-NA-355 for shudder diagnosis. In severe cases, the valve body or complete transmission may need replacement.
Est. Cost: $150 (fluid flush) - $3,000 (torque converter or transmission replacement)Electrical System Voltage Drops and Battery Drain
The 2018 Impala is prone to parasitic battery drains that kill the battery overnight or within a few days of sitting. Owners report the car failing to start, dimming headlights, flickering dash lights, and infotainment system resets. The issue is often traced to the body control module (BCM) not properly entering sleep mode after the vehicle is turned off.
Dealer performs a BCM software update to correct the sleep mode timing. If the drain persists, a parasitic draw test should be performed to identify the offending module. Battery replacement with a proper AGM battery and terminal cleaning may also be needed. Reference GM TSB 16-NA-049 for parasitic drain diagnosis.
Est. Cost: $0 (software update) - $500 (BCM reprogramming and battery replacement)Power Steering Fluid Leak from Rack and Pinion
The hydraulic power steering rack develops leaks at the input shaft seal and internal seals, causing a gradual loss of power steering fluid. Owners notice a whining noise from the power steering pump, increased steering effort, and fluid puddles under the front of the vehicle. Low fluid levels can damage the power steering pump if not addressed promptly.
Replace the power steering rack and pinion assembly. Top off or replace the power steering fluid and inspect the pump for damage from running dry. Some owners add power steering stop-leak as a temporary measure, but the seals typically continue to degrade.
Est. Cost: $600 - $1,500Air Conditioning Compressor Failure
The A/C compressor can fail prematurely, resulting in warm air from the vents. Owners report the A/C blowing cold intermittently before failing completely. A loud grinding or clicking noise from the compressor clutch may precede total failure. Metal debris from the failed compressor can contaminate the entire A/C system.
Replace the A/C compressor, receiver/drier, and expansion valve. If the compressor has shed metal debris, the condenser and all A/C lines must be flushed or replaced to prevent contaminating the new compressor. Evacuate and recharge the system with the correct amount of R-134a refrigerant.
Est. Cost: $800 - $2,000MyLink Infotainment Screen Delamination and Freezing
The 8-inch MyLink touchscreen display develops delamination where the screen layers separate, creating bubbles, discolored areas, and unresponsive touch zones. The system also freezes, reboots randomly, and loses Bluetooth connectivity. The delamination is caused by heat exposure and adhesive breakdown and worsens over time.
Replace the infotainment display unit. GM released updated display units with improved adhesive and thermal management. A software update may resolve freezing and Bluetooth issues but will not fix physical delamination. Aftermarket replacement screens are available at lower cost.
Est. Cost: $400 - $1,200
