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.

The GM bulletin N19227110 indicates that they are aware of over 10% of Chevrolet Spark models from the years 2014-2015 experiencing transmission problems. Although this bulletin expired last year, it is important to note that they do not provide coverage for vehicles purchased used with fewer than 120,000 miles. This situation poses a significant danger, as the transmission may potentially be contaminated with dirt and debris, leading to unexpected jerking or complete failure, and in some cases, vehicles have caught fire. Furthermore, unless the vehicle is taken to a GM service center, the issue may remain undetected. According to my research, this problem is similar to the one that Nissan faced with their CVT transmissions, which were subject to a recall for the same reason.
