2017 Chevrolet Impala — Known Issues & Recalls

Your check engine light came on while driving. A mechanic found problems with your catalytic converter, transmission oil cooler hose, and transmission itself. Even after repairs, the same problems returned, and the mechanic said your transmission needs to be replaced. This happened at 129,000 miles.

While driving uphill at 40 mph, your car lost power and wouldn't accelerate even when you pressed the pedal hard. The problem started intermittently but became a regular issue, with the transmission overheating warning light turning on during later failures. Before the main failure, you may have noticed the transmission jerking and hesitating. Your dealer diagnosed that the transmission needs to be replaced.

Your transmission is jerking severely when shifting from first to second gear, causing physical discomfort. The dealership confirmed the issue and found leaking transmission coolant lines. The manufacturer has scheduled an inspection to diagnose the root cause of the jerking and fluid leak.

Your air conditioning stopped working in June 2020 due to a failed evaporator core, which a Chevrolet dealer confirmed. You discovered that Chevrolet issued a special coverage adjustment for 2016-2018 model-year cars with this exact problem, making the repair free under warranty, but you never received the notification letter. The dealer won't perform the free repair without the documentation, even though your car qualifies. You'll need to contact Chevrolet directly or revisit the dealer with the NHTSA case number (N182186881) to get the evaporator core replaced at no charge.

No specific complaint details were provided for this report.

Your car's radio turns on, but no sound comes out of the speakers. This could be caused by a muted audio system, speaker failure, or an issue with the radio itself. A technician would need to check the audio settings, test the speakers, and inspect the radio unit to identify and fix the problem.

Your car pulls to the right on its own without you turning the wheel. A mechanic discovered your rack and pinion (the part that controls steering) is failing. The dealership said this steering component isn't covered under warranty and that the replacement part is unavailable nationwide, making the car unsafe to drive.

A warning message appeared on your dashboard saying to drive with care due to power steering assist issues. When you took the car to the dealership, they diagnosed that the power steering gear has failed. This means your power steering system isn't functioning properly, making the steering wheel harder to turn. The repair will likely involve replacing the power steering gear assembly.

You purchased a 2017 Chevrolet Impala from a dealer, but discovered a serious mileage discrepancy during registration. The odometer showed 117,892 miles at purchase, but the vehicle's registration records indicated only 64,484 miles — a difference of over 53,000 miles. This suggests the odometer may have been rolled back or the vehicle's mileage history is incorrect. You'll need to work with the dealer and your state's registration authority to investigate the true mileage and resolve the odometer fraud claim.

While driving on the interstate, your hazard lights suddenly turned on and your trunk popped open on its own. You couldn't close the trunk securely, so you had to use a net to hold it shut. Shortly after, your car lost all power and wouldn't restart. The dealer found that your body control module (the computer that manages electrical functions) had failed, and your trunk latch was broken. Both components were repaired.

Your catalytic converter pipe on the front left side of the engine cracked and was replaced under warranty at 37,000 miles, but has cracked again at the same location at 88,000 miles. The repeated failure caused excessive heat that melted the fan housing, creating a potential safety hazard. The repair is no longer covered by warranty, and you believe this indicates a design or manufacturing defect rather than normal wear.

Your car's catalytic converter has cracked, which is reportedly a recurring issue with this model. A cracked catalytic converter can reduce engine performance and may cause the check engine light to come on. The converter will need to be replaced to restore proper exhaust function.

You were in a crash at 30 MPH where your Impala's front end hit another vehicle's passenger door. Your airbags did not deploy during the impact, even though the collision caused front-end damage. You experienced neck pain, back pain, and bruises but did not seek medical care. The airbag system was never inspected or repaired after the crash.

Your car suddenly started jerking while you were driving, then completely stalled and had to be towed. OnStar indicated the problem was with the engine control module (ECM) and transmission control module (TCM), which are the computers that manage your engine and transmission. This type of failure can be dangerous when it happens on the road. Fixing this will likely involve diagnosing and possibly replacing one or both of these control modules.

Your 2017 Impala was involved in a serious crash when a tractor-trailer hit the front passenger side at 50 mph, but the airbags failed to deploy. You sustained injuries to your back, spine, torso, arms, knees, and shoulders that required medical treatment. Additionally, the doors locked with the keys still inside, and you needed a locksmith to open them. The airbag failure and door lock issue both need investigation to determine what went wrong.

Your air conditioning system is blowing hot air instead of cool air because the evaporator core has failed. In hot climates, this causes interior temperatures to exceed 150°F, creating a serious safety risk for heat stroke, heat exhaustion, and driver distraction. Replacing the evaporator core will restore your AC to normal operation.

Your air conditioner is blowing hot air instead of cold, and the evaporator core is leaking refrigerant (Freon) into your cabin. The dealer diagnosed failures in both the evaporator core and the A/C compressor. Both components will need to be replaced to restore proper air conditioning function.

Water continuously leaks into your trunk and spare tire compartment after rain, causing mold and odor. You've found that this issue has been recalled for some model years but not yours. You're repeatedly having to remove water and dry the area to prevent damage.

Your air conditioning stopped working properly without any warning light showing up. The dealer found leaks in the A/C evaporator and compressor, which required repairing the instrument panel to access — this has been fixed. You're also experiencing an abnormal noise from the steering wheel when you turn, which hasn't been repaired yet. Fixing the steering noise may involve inspecting the steering column components and lubrication.

Your check engine light is coming on, and it may be related to a malfunctioning active shutter on the front of your vehicle. The active shutter is a component that helps manage airflow to improve fuel efficiency. You'll likely need a diagnostic scan to confirm the issue and determine if the shutter needs repair or replacement.
