The 2017CHEVROLETIMPALA carries 134 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 6 crashes, 0 fires, 10 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 5/5 rating, with 5/5 front crash, 5/5 side crash, and 4/5 rollover scores derived from standardized barrier and dynamic tests.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2017 IMPALA is unknown or other with 29 filings, followed by engine (21) and air bags (17). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 57 investigation files overlapping the 2017 IMPALA, and 2 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

Power steering assist drive with care warning popped up on dash. Took the vehicle to the dealership and they said the power steering gear failed.
I am writing to formally express my deep dissatisfaction regarding a recurring issue with my vehicleâs catalytic converter pipe. At 37,000 miles, the left-hand (front bank) catalytic converter pipe near the cylinder head mounting flange weld failed and was replaced under warranty by GM. Now, at just 88,000 miles, the same pipe has cracked againâat the identical locationâand is not being covered by GM, forcing us to pay for repairs out of pocket. This is not simply a case of wear and tear. The failure not only resulted in significant performance issues, but also caused the housing of the fan to melt due to excessive heat exposure, posing a serious safety hazard. This repeated failure clearly indicates a design or manufacturing defect, and Iâm appalled that GM has not acknowledged this as a broader issueâdespite evidence suggesting this is a known and frequent problem with this vehicle model. In my view, the failure of the same part in the same location twice, within a relative
I've only had my car for about 2 1/2 months, when I started to notice my car moving to the right without me moving it. I figured it needed a front-end alignment. So, I took it to a mechanic. Once he got it up on the stand, he noticed something wrong with the front suspension. He didn't do the alignment, but he told me that my "Rack and pinion" was going out. I then made and appointment with the dealership. They looked at it and told me it was my steering and that it wasn't cover under my warranty and that the part to fix it was "Nowhere in the country to be found", and if I brought the part to them. They wouldn't put it on. So now I have a car note and insurance bill on a car that I'm afraid to drive. What are people supposed to do about these cars? It would seem that It's not just a me problem.

Catalytic converter cracked and is a huge problem with these cars
I have had this car for a few years and the evaporator core has failed, the car will blow air but it is very VERY hot air. The faulty evaporator core is a direct result of GM using cheaply made parts not inspected to the standard prior to installation into the vehicle. having previously owned this car in Hawaii and still owning it in a hot climate, the interior temperature exceeds well over 150 degrees Fahrenheit. This presents a serious safety hazard due to the potential for heat stroke, heat exhaustion and heat cramps which can effect the ability of the driver to control the vehicle appropriately. Children in the back seat, the elderly and even competent adults ARE AT RISK. NO ONE should be expected to pay to repair a safety hazard that GM has known about and ignored other than a bulletin the left many owners without a repair. This issue is clearly a serious safety concern and should be handled appropriately by GM.

I continuously have water leaking into the trunk of my 2017 Chevrolet Impala, specifically the spare tire compartment. I noticed through research that the issue has been recalled for select years, but not my vehicle year. If the issue is a known defect, this should be covered by the vehicle manufacturer. I am constantly having large amounts of water after rain and it is causing a moldy smell. I try to scoop water and then dry the area, however this is a repeat issue.
