Description of the problem | This vehicle's erratic downshifting and upshifting of the automatic transmission causes abrupt changes in acceleration and deceleration that sets up sequences that force the driver to continually press down on, or let up, on the break and or accelerator to attempt to blend in with stop-and-go traffic. In very heavy traffic, present when entering or leaving large cities, the onset and continuance of this vehicle's performance worsens resulting in driver fatigue and extreme stress, brought on by the ever present necessity to be extra watchful and to maneuver to avoid hitting the vehicle in front, or being rear-ended. When driving through mountainous terrain at today's interstate speeds, there is recurring "bumping" that sets up when ascending long grades. It creates the feeling that either the transmission is attempting to downshift but then changes its mind, or the engine's rpm are about to increase but don't. This adds to fear of imminent failure and being left stranded. This behavior was present from the very first time the vehicle was driven. It's getting worse. This driver believes the unsafe operating performance of this vehicle as described above, is exacerbated by the combination of the small, 4 cylinder engine coupled to the 6 speed transmission, that requires the engine to rapidly downshift or upshift to provide the needed performance required in today's driving environments. Further, it is evident the software controlling the transmission's operating behavior was neither fully developed nor tested throughout its anticipated full operating range and as such creates a vehicle that is dangerous to operate on public roads attempts to have these issues addressed with the dealer resulted in being told..." nothing can be done... The problems you are encountering are being are being experienced by many customers. Chevrolet is not providing any solutions". |
