| Engine And Engine Cooling problems |
The vehicle has developed a persistent, severe rattling noise coming from the engine bay and front chassis area. The noise becomes significantly worse and amplifies at highway speeds, raising severe concerns about high-speed mechanical instability. The vehicle has undergone multiple repair attempts at an authorized dealership, but mechanics have been unable to identify or resolve the root cause of the noise. The vehicle is currently considered unfit for road use and has remained restricted to the dealership repair facility for 29 consecutive days since October 2, 2026. Because the source of this heavy mechanical rattle cannot be identified by factory technicians and worsens at speed, it presents an immediate safety risk. An unresolved, unknown mechanical defect in the front end or engine compartment raises serious concerns regarding potential sudden component failure, steering/suspension compromise, or structural detachment while operating at high speeds, which could result in a catastrophic loss of vehicle control.
