I purchased a MagnaFlow aftermarket catalytic converter system for my 2008 GMC Yukon SLT 5.3L through Walmart’s online marketplace, sold by a third-party vendor called OurDealsRock. The product was advertised as “50-state legal” and compatible with vehicles registered in New York State. However, shortly after installation, my check engine light turned on, and diagnostic codes P0420 and P0430 (Catalyst System Efficiency Below Threshold) appeared. Initially, I thought this was a minor sensor issue, but over time, the vehicle’s performance gradually deteriorated. I noticed reduced acceleration, poor fuel economy, and eventually significant loss of power. The vehicle began shaking under load, misfiring, and overheating. These symptoms worsened steadily—not immediately—but progressively after continued driving with the aftermarket converter installed. I had the vehicle inspected by a certified mechanic, who confirmed that the MagnaFlow converter was not CARB-compliant, was not approved for use in New York, and that it had been illegally marketed as such. He also informed me that prolonged use of a non-compliant, malfunctioning converter caused excessive backpressure, leading to complete engine failure over time. The diagnosis was confirmed by a second mechanic before I committed to the engine replacement. The product was later removed from Walmart’s site, becoming unavailable for sale in my zip code [XXX] ) shortly after my initial complaint. This shows clear acknowledgment that it should never have been sold to a New York consumer in the first place. But by the time it was taken down, the damage had already been done. Component/system that failed: •MagnaFlow aftermarket catalytic converter system •Ultimately caused failure of the vehicle’s engine block Safety concerns: •My family and I were unknowingly driving with a damaged and failing engine •The vehicle’s degraded performance, overheating, and power loss could have compromised our safety during highway d INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When beginning to drive forward after coming to a stop at an intersection. The vehicle will often stall in the middle of the intersection. Requiring me to switch it transmission into natural and restart it as it’s rolling. I almost gotten rear ended many times I always get honked at. It just a matter of time before it causes an accident. It sometime happens after turning as well. I looked at forums on this gmc Yukon hybrid. And it looks like many other owners are asking the same question and nobody is coming up with any answers. Other customers say the dealer told them the hesitation is Normal. I took my truck into a local repair shop and he called me after three weeks saying it was done, but it still had the check engine light on and still is stalling out in intersections. Charge me $2000. This has been happening daily since I got the vehicle

It started shutting off at a light for autostop.but when it would turn green it would intermittently just drop out of autostop without restarting. Then may start back up or maybe not, many time after restarting at the light it would died in the middle of the inspection. A parasitic draw kept killing the accessory 12 V battery replaced the 12 V battery but the problem continued. When the truck was running it would run flawlessly,before stalling. The code said to replace the auxiliary fluid pump. I had it a new auxiliary fluid pump installed. After this the vehicle wouldnt crank. They then worked through a service bulliten fixing a list of areas were the harness was chaffed and shorted. The truck has been out of commission the past 10 months and intermittently started twice during this time, it ran rough for 5 mins and died out at the first stop sign and wont crank again. Some times it will crank but not start.

Driving north on I-94, leaving the city of Chicago, the rear driver side tire (Bridestone Dueler P285/45R22) blew and the outer side wall seem to have a defect (weak side wall). This should never happen in a passenger car and the manufacturer should have better QUALITY CONTROL and prevent these defects from leaving the plants. I have a MS in Mechanical Engineering and have knowledge of the tire designs, as we did research for Firestone in the 1980's at my university, and this is definitely a defect within a weak part of the fabric in the sidewall. If you would like the tire for your investigation, please let me know ASAP. Other industries like the Medical and Pharma areas would not allow this kind of thing to happen and passenger vehicles with defective parts or components should never jeopardize any passenger to be in this kind of situation. Luckily, it was very early in the morning, with very light traffic, and no one in my car or any of the cars around me got hurt, as I was able to maneuver to the right side of the highway.
