The transmission failed, shifting is no longer smooth. It hesitates and shakes the entire car, and the car slows down to almost a crawl uphill. I understand this is an issue with Chevrolet Impalas. So now I have an $8200 bill for a problem I was never told about, and that GM knew that it existed. So, yes, the issue has been identified, reproduced and confirmed by the dealer. The warning light came on when the issue happened, so it was already too late. The issue began with just over 65,000 miles. So I have a 2018 Impala in almost perfect condition in need of an $8200 before taxes, transmission replacement. I would like some help from the NHTSA, like requiring GM to pay for the repairs. Thank You very much.

The electronic power steering intermittently fails while driving, especially during or after wet conditions. Without warning, the steering wheel becomes extremely stiff and difficult to turn, and a “Service Power Steering” message appears. The failure occurs at any speed and lasts about 1–3 minutes before returning to normal. This has happened multiple times under similar conditions. This creates a serious safety risk because it occurs at highway or city speeds without warning, making the vehicle difficult to control and increasing the risk of a crash. No prior warning is given before the failure other than the dashboard message at the time of the incident. Cause is UNKNOWN. There are numerous reports from other drivers describing similar symptoms, suggesting a potential widespread defect in the electronic power steering system or related components.

The component is the Evaporative Emission Control System (EVAP) Vapor Canister Purge Valve.The internal diaphragm or solenoid of the factory-installed purge valve has worn out prematurely or became contaminated, locking it permanently into a stuck-open position.The Manifestation or (Symptoms): The stuck-open valve continuously drafts raw fuel vapor and unmetered air into the engine intake manifold. This causes an improper air-fuel mixture, resulting in:Stumbling / Failure to Start Immediately After Refueling (the engine is flooded by gas tank vapors forced in during fill-up).Rough Idling (due to a continuous vacuum leak).Illuminated Check Engine Light tracking Diagnostic Trouble Codes (DTCs) P0496 (High Purge Flow) or P0442. Yes, it is available for inspection. The vehicle stumbles, hesitates, and fails to restart at busy gas pumps and intersections which places drivers, passengers, and other motorists at an immediate risk of a collision. Yes, the problem has been validated by an professional auto mechanic shop. No, it has not been inspected by anyone else other than the mechanicshop to diagnose the problem, issue. The check engine light came on as I cranked the vehicle up and it started idling. No known symptoms until check engine came on prior to failing.

I am filing this complaint regarding a widespread design defect affecting 2016-2018 Chevrolet Impala vehicles with 3.6L V-6 engines, and General Motors' systematic denial of legitimate warranty claims under Special Coverage Adjustment N182186881-01 through arbitrary VIN-based exclusions. My 2017 Chevrolet Impala Premier (VIN: [XXX], in service August 5, 2017) developed an evaporator core failure in summer 2020, prior to reaching 72,000 miles -- within GM's published coverage window. Despite meeting every published criterion, GM denied coverage, claimed my VIN was excluded, and has refused to provide any substantive explanation of the exclusion criteria. GM's Special Coverage bulletin explicitly committed to notifying affected customers. I never received notification, despite GM demonstrably having my contact information (I received airbag recall notices for the same vehicle). This failure caused me to lose the benefit of both the Special Coverage and a separately purchased $1,766.00 extended warranty -- a documented double loss. My vehicle has been without air conditioning for over four and a half years. Documented expenses: $671.02 in diagnostics, $206.00 unreturned deposit to Criswell Chevrolet (Gaithersburg, MD). Repair estimate: $1,700-$2,680. Other 2017 Impala owners report identical VIN-based denials despite meeting all published criteria. I have filed complaints with the Maryland AG, BBB, and Montgomery County OCP (Case No. XXX active mediation). GM's Executive Resolution Team failed to meet my written response deadline of December 11, 2025. Complete documentation (100+ pages) available upon request.

AIR BAGS
For the last 2 years, the car willl come up saying airbag system issues. There airbag sensor under the passenger side seat will randomly throw a code for the erorr and then turn off. It does not have to be a bump, move the seat, Just goes off. We have had it professionally scanned and it is always the same sensor with the issue. We noticed certian models had recalls but our was not on the list for some reason even though it fits all the other models with same issue. The cost to get it repaired and a chevy dealer is astromical. There are too many dates to count of the light and sesnor error.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING
I have always kept my Impala in my garage until recently I started keeping my grandson a few days a week. When I am at that home my car is parked in a driveway open to the elements. About a month after starting I notice that my car started having what I would describe as an electronic issue. The seat belt alarm would go off without me ever touching my seat belt. I have also had to replace my tail lights in my vehicle twice since this started. Then when I packed for a trip yesterday I noticed an awful smell in my trunk. I could not find the source, so I took everything out of my trunk and opened the spare tire compartment which was completely filled with water! I found a Product Bulletin on this. Chevrolet #14047. But it is NOT A RECALL. WHY IS THAT? IT IS CLEARLY AN ERROR ON THEIR PART! CAN YOU EXPLAIN PLEASE?

I brought my vehicle into Chevrolet due to my vehicle locking down and thinking the vehicle is being stolen. They told me that the side module malfunctions due to rain and weather conditions. He then says the part is on back order for possibly 12 months or greater! I drive for my job and blinkers and everything safety shuts down to make It unsafe to sell or be driven. I am at a loss to know how to proceed. I will be contacting the minnesota Attorney General as well. Help please
