2017 Chevrolet Impala other reported problems

UNKNOWN OR OTHER

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.

There is a recall for my vehicle with the evaporator core freezing leaking on certain chevy 2017 impala just like mine and my car has the same issue but they only recalled a certain number of vehicles with this problem. Is there anything I can do to resolve this issue.

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.

Evaporator Core failed. My safety isn't at risk although I get very hot riding in the car without AC. It was confirmed by a dealer. It has not been inspected by police or anyone else other than a dealer. No warning lamps or messages. My 2017 Chevrolet Impala has been without Air Conditioning since approximately June 2020. I took it to a local Chevrolet dealer and they diagnosed it stating the Evaporator core had failed. After doing research online, I found a Special Coverage Adjustment N182186881 on nhtsa.gov stating that on some 2016-2018 model-year cars, the evaporator core may become damaged and the customer is eligible for it to be replaced at no charge. I never received this paper in the mail saying mine was affected but mine was affected. Due to me having no copy of this, no dealer will fix it free of charge. I am not just looking for a free repair, I am looking for it to be repaired for free specifically due to the fact it has been affected. There is less than 72,000 miles on my vehicle.

The exhaust manifold cracked, took to shop to see if can weld and was told it is connected to the Cadillac converter. This was putting MAJOY exhaust fumes into car. making myself and children sick. at the shop they said this is VERY COMMON and he is not sure WHY no recall has been placed on this and why they wont fix. In the process of saving to get this fix the car rode rough, stalled, exhaust fumes and sensor's went. I replaced and I am now HAVING this issue AGAIN. Chevrolet needs to get this fixed and a recall should be done. Had this car just for a year and I SWEAR once warrenty went EVERYTHING this

Mechanic confirmed Evaporator Core leak, which is leaking Freon faster than can be put in. Leaking Freon is a safety concern, as well as the resultant lack of Air Conditioning. The car becomes very hot inside, and the Air Conditioning does not blow any cold air, creating potential for overheating, heat stroke, heat exhaustion, etc. in addition to general discomfort.

Found leaking bright green substance on driveway. AC disabled/blowing air with no cooling affect. After trying to reach Donovan at an 800 number referenced in other complaints that number is now associated with 3M disability program. This is very much a health issue and should be a national recall. The evaporator core must be replaced at no cost to the vehicle owner as this is a known defective part. Freon is dangerous to breathe.

I NOTICED THE CAR'S (2017 CHEVROLET IMPALA) A/C WAS BLOWING HOT AIR WHILE STATIONARY AND IN MOTION. I TOOK IT IN FOR AN A/C CHECK. PER THE CHEVROLET DEALERSHIP'S SERVICE ADVISOR, THERE IS AN EVAPORATOR CORE LEAK INTO DASHBOARD. GM HAS RELEASED TWO SPECIAL OVERAGE BULLETINS (N182186880 & N182186881) IDENTIFYING THE ISSUE AND THE YEAR, MAKE, AND MODEL (2016-2018 IMPALAS 3.6). ALSO, PER THIS BULLETIN, IT STATED IT IDENTIFIED THE VINS THIS IMPACTED, BUT I HAVE THE SAME ISSUE AND CAR. IT DOES NOT STATE WHY SOME IMPALAS WERE NOT SELECTED. BUT DIFFERENT FORUMS ON THE INTERNET, SHOW THERE ARE MORE IMPALAS AND THEIR OWNERS WHO HAVE THIS SAME ISSUE. SEE HTTPS://WWW.IMPALAFORUMS.COM/THREADS/EVAPORATOR-REPLACEMENT.1841471/ . DUE TO VOLUME OF OTHER COMPLAINTS, I BELIEVE THIS SHOULD BE A NATIONAL RECALL. THIS IS A SAFETY ISSUE ESPECIALLY DURING THE SUMMER MONTHS.
