2017 CHEVROLET IMPALA

ENGINE

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.

STEERING

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.
