June 18, 2026 — A recent incident report details a dangerous malfunction involving a 2024 Coolster 110cc ATV-3050C, manufactured by E COOLSTER DBA MAXTRADE LLC. A consumer reported that the ATV spontaneously accelerated to full throttle after being stopped, resulting in the user being dragged and injured. This incident highlights critical safety concerns regarding throttle control and remote kill switch functionality on ATVs.
Product Details
Incident Overview
The incident involved a new 2024 Coolster 110cc ATV-3050C, purchased on May 2, 2026. The ATV was first ridden on May 7, 2026, and had accumulated less than one hour of total use across three separate occasions before the incident.
On Saturday, May 9, 2026, the owner’s son was riding the ATV within a designated boundary. When the son rode past this boundary, the owner activated the remote kill switch to stop the vehicle. The ATV did stop, but the son reported that it “wouldn’t slow down” and “couldn’t stop” before it did.
Upon attempting to restart the ATV, it immediately and unexpectedly surged to full throttle on its own. The uncontrolled acceleration caused the ATV to pull the owner to the ground and drag them, resulting in injuries. The owner managed to regain some control by pulling the ATV onto its back wheels, allowing them to reach and activate the kill switch on the handlebars, finally stopping the runaway vehicle.
Following the incident, on Monday, May 11, 2026, the owner contacted the dealer, Four Seasons Power Sports, to report the serious safety issue and request a refund. The dealer advised that no action could be taken until the ATV was brought in for inspection by a certified mechanic. However, the owner chose not to alter the ATV’s state and has not brought it in, instead pushing it back into the garage and leaving it untouched to preserve its condition for reporting to the CPSC.
Safety Concerns
This incident presents severe safety concerns related to the Coolster Mountopz ATV-3050C’s throttle control system and remote safety features:
- Uncommanded Acceleration: The primary danger is the ATV’s ability to engage full throttle spontaneously, either after being stopped or upon attempting to restart. This unpredictable behavior can lead to a complete loss of control.
- Malfunctioning Kill Switch/Throttle Linkage: The report suggests a potential defect in the ATV’s throttle mechanism or its interaction with the kill switch system. If the remote kill switch stops the engine but the throttle linkage remains engaged or re-engages upon restart, it creates an extremely hazardous situation. The son’s comment about the ATV not slowing down before it stopped also points to potential throttle issues even before the restart attempt.
- Immediate Dangers: Riders can be thrown from the vehicle, dragged, or collide with obstacles at high speeds, leading to severe injuries such as fractures, lacerations, head trauma, and internal injuries. Pedestrians or bystanders in the vicinity are also at extreme risk.
- Long-Term Risks: If not addressed, this defect could lead to repeated incidents of uncontrolled acceleration, resulting in further injuries or even fatalities. The unpredictability makes it impossible for users to anticipate or prevent such events.
- Who Might Be Affected: While the incident involved an adult, 110cc ATVs are often used by children and young riders. The risk to less experienced or younger riders is amplified, as they may lack the strength, reaction time, or judgment to handle an unexpected full-throttle surge.
- Property Damage Potential: An out-of-control ATV can cause significant damage to property, including structures, fences, and other vehicles.
What Consumers Should Do
Consumers who own a Coolster Mountopz ATV-3050C, particularly the 2024 110cc model, should take immediate precautions:
- Stop Using Immediately: If you own this model ATV, especially if you have experienced similar issues, cease all use immediately. Do not attempt to operate or troubleshoot the vehicle.
- Inspect Your Product: While specific visible defects related to this throttle issue might not be obvious without expert inspection, be aware of any unusual engine behavior, throttle stickiness, or inconsistent responses to controls.
- Preserve Evidence: If you have experienced an incident, do not alter the ATV’s condition. Preserve it in its current state, as described in the incident report, for potential inspection by authorities or experts.
- Report Incidents: It is crucial to report any incidents, malfunctions, or safety concerns with consumer products to the U.S. Consumer Product Safety Commission (CPSC) at www.SaferProducts.gov. Detailed reports help authorities identify trends and initiate recalls.
- Contact the Manufacturer/Retailer: Reach out to E COOLSTER DBA MAXTRADE LLC or the retailer where you purchased the ATV to report the safety issue and inquire about potential remedies or returns. Be sure to document all communications.
