Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The mounting bracket welded to the front exhaust pipe (near the flex section) broke off due to weak factory welds. As a result tearing a hole in my exhaust pipe and potentially leading to exhaust fumes leaking into the cabin of the vehicle.

NHTSA complaint #11754749, filed 2026-08“We bought our car in 2021 and shortly after our car started pouring water into the driver seat from the ceiling. At that time we thought it may have been a cracked window window. Actually we weren’t really sure because we don’t use the sunroof or anything really.

NHTSA complaint #11567276, filed 2024-01“My car starting making a loud noise upon start up and continued while driving, sounded like a GoCart exhaust system and was not normal.

The dealer (Elco Chevrolet) confirmed the problem upon hearing and looking under the car, there is a bracket broken on the exhaust system and the catalytic converter has a hole/crack in the molding. …”

NHTSA complaint #11558170, filed 2023-12“While driving my car in normal weather/temperature conditions, the driver side sunroof literally exploded. There was a very loud bang, like someone fired a gun next to my head, and initially I thought someone had shot out one of my car windows with a gun. Upon seeing it was the sunroof I then thought an object had falled through the sunroof window. However, upon inspection, the sunroof window glass was actually blown from the inside out. See attached photographs. There was no prior apparent damage/crack/chip to the sunroof glass or mechanism. …”
