The vehicle taken to an independent mechanic where it was diagnosed that the transmission failed and needed to be replaced. The vehicle was not repaired. The vehicle was then taken to the residence.

“The vehicle experiences intermittent loss of power and unstable acceleration while driving at normal speeds (approximately 45–55 mph). The vehicle will surge, hesitate, and fail to maintain consistent speed, creating an unsafe condition in traffic. While driving, the vehicle does not consistently respond to throttle input and may unexpectedly lose acceleration. This creates a risk of being rear-ended or being unable to safely merge into traffic. The condition occurs during normal driving and has progressively worsened over time. Diagnostic testing indicates transmission-related faults involving pressure control and internal speed monitoring. This issue affects the safe operation of the vehicle and appears consistent with known transmission problems reported for this vehicle model. Supporting documentation has been provided, including manufacturer service program records indicating this vehicle was previously subject to a known transmission-related defect condition.”

“Without warning, car began to drop out of 5th gear while driving, entering Neutral at high speeds. This is a manual transmission and you can see the shifter physical move itself into 5th gear. Driver almost lost control of the vehicle out of surprise to what had just happened. When searching in Reddit, this appears to be a widespread issue for this year/make/model. Took to local Chevy for diagnostic, was told it would be a $7,500 repair to replace the transmission.”

“The contact owns a 2014 Chevrolet Spark. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. Additionally, the transmission was shifting hard. The diagnostic trouble codes: P0700 and P0841 were retrieved after the failure. The vehicle was taken to an independent mechanic, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The contact referenced an unknown recall repair that was performed in May 2016, where the transmission pulley was replaced. The contact stated that the recall repair had failed to prevent a failure.

At Maher Chevy St. Petersburg Florida, they said there was nothing they could do. problem has been throughout vehicles life. And they made us believe they were changing the transmission.”
