   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.

   The contact owns a 2017 Chevrolet Impala. The contact stated that while driving at an undisclosed speed on the interstate, the hazard light was activated and the trunk spontaneously opened. The contact was unable to securely latch the trunk and used a net to secure it. While continuing the drive, the vehicle lost motive power and was unable to restart. The vehicle was towed to a local dealer, where a diagnostic test determined there was a failure with the body control module(BCM), and a malfunction with the trunk latch assembly. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 66,890.

6. Filed Jul 21, 2025Failure Jul 20, 2025Clearwater, FLEngine

   I am writing to formally express my deep dissatisfaction regarding a recurring issue with my vehicle’s 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 again—at the identical location—and 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 I’m appalled that GM has not acknowledged this as a broader issue—despite 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 relatively low mileage span, reflects an unacceptable lack of quality control. It is deeply disappointing that GM has not issued a recall or offered to cover this repair, which is demonstrably caused by the same flaw as before. This situation feels less like responsible customer support and more like an attempt to profit from known issues, leaving loyal customers to shoulder the financial burden. I am requesting immediate reassessment of this case, full coverage for this second repair, and a formal acknowledgment of this defect. I also encourage GM to investigate this issue further and consider issuing a recall to prevent others from experiencing similar damage and expenses.

   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.

    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.
