Incident Overview

According to a report filed with the CPSC on May 9, 2026, the consumer purchased a new 2024 Coolster 110cc ATV from a dealer on May 2, 2026. The vehicle was first started and ridden on May 7, 2026, and was used only three times for a total of less than one hour before the incident occurred. On the day of the incident, the consumer's son was riding the ATV within a designated boundary while the consumer monitored closely, ready to use the remote kill switch if needed.

When the child rode past the boundary, the consumer activated the remote kill switch, which stopped the ATV. However, the child reported that the ATV would not slow down and he could not stop it. When the consumer attempted to restart the vehicle, it immediately went to full throttle on its own. The ATV pulled the consumer to the ground and dragged them, causing injuries. The consumer was able to regain control by lifting the ATV onto its back wheels and hitting the handlebar kill switch. The consumer contacted the dealer on May 11, 2026, but was told nothing could be done until a certified mechanic inspected the ATV. The consumer has not started or altered the vehicle since the incident, preserving it for investigation.

Safety Concerns

Immediate Dangers: A loss of control hazard like unintended full-throttle acceleration can cause the vehicle to lurch forward unexpectedly, throwing the rider or dragging bystanders. In this case, the consumer was pulled to the ground and dragged, resulting in injuries that required first aid. The inability to stop the vehicle via the remote kill switch compounds the risk, as the operator may be unable to regain control.

Who Might Be Affected: Both riders and nearby individuals are at risk. The primary rider—often a child in the case of youth ATVs—may be thrown or unable to stop. Bystanders, including parents attempting to intervene, can be struck or dragged by the vehicle, as occurred in this incident.

Warning Signs: In this incident, the ATV exhibited a failure of the remote kill switch to function as intended. While the switch initially stopped the vehicle, it could not prevent the subsequent unintended acceleration. Any instance where a kill switch fails to respond, or where the vehicle accelerates without throttle input, should be treated as a critical warning sign.

Environmental Triggers: Although no specific environmental trigger was identified in this report, the failure occurred shortly after the vehicle was first used, suggesting a potential design or manufacturing defect rather than wear-and-tear. The ATV was used as intended on level ground under parental supervision, indicating the hazard can arise under normal operating conditions.

What Our Clients Say

What Consumers Should Do

Stop Using Immediately: If your ATV exhibits any unintended acceleration or kill switch malfunction, cease operation and do not attempt to ride it again until it has been inspected by a qualified mechanic or the manufacturer.

Preserve the Product: Do not alter, repair, or modify the ATV. Keep it in the condition it was in at the time of the incident, as any changes could compromise an investigation. Store it in a safe location away from children.

Document the Incident: Take photographs and videos of the ATV, especially the throttle, kill switch, and remote control. Write down the date, time, and sequence of events. Keep receipts, purchase documents, and any correspondence with the dealer or manufacturer.

Seek Medical Attention: Even if injuries seem minor, have them evaluated by a medical professional. Some injuries, such as soft tissue damage or internal injuries, may not be immediately apparent.

Report to the CPSC: File a report at SaferProducts.gov to alert regulators and other consumers. Include as much detail as possible, including the product model and incident circumstances.

Check for Recalls: Visit CPSC.gov to see if the manufacturer has issued a recall or safety notice for this model. Recalls may provide a remedy such as a free repair or replacement.
