Chile’s consumer protection agency has issued a safety alert affecting nearly 1,700 vehicles from two major American automotive brands due to a potential engine control defect that could lead to unexpected stalling while driving.
The National Consumer Service (Sernac) announced the alert on April 21, 2026, covering 1,689 Jeep Grand Cherokee and Ram 1500 models sold in Chile between 2013 and 2020. The issue stems from a possible fault in the powertrain control module (PCM), which may disrupt signals from the engine rotation sensor and result in loss of engine synchronization or sudden shutdowns.
According to Sernac, the defect involves the potential detachment of internal material within the PCM, interfering with the rotation sensor’s signal. This could cause drivers to experience unexpected engine stalling, failure to start, or loss of power while in motion, increasing the risk of accidents, particularly at higher speeds or in heavy traffic.
The agency emphasized that the remedy consists of reprogramming the PCM, a procedure taking approximately one hour and provided free of charge to affected vehicle owners. Sernac urged owners to verify whether their vehicle is included in the alert using the vehicle identification number (VIN) through the agency’s official website.
Both Jeep and Ram have established dedicated customer service channels to assist owners, including call centers and online resources. The Ram support line is available at 800 380 204, while Jeep owners can contact 800 380 216 for guidance on scheduling inspections and repairs.
Sernac noted that the alert applies specifically to vehicles commercialized in Chile during the stated period and does not extend to models sold in other markets unless separately identified by local authorities. The agency continues to monitor the situation and recommends prompt action to mitigate potential safety risks.
As of the announcement date, no accidents or injuries have been publicly linked to this specific defect in Chile. However, Sernac stressed the importance of preventive maintenance to avoid possible hazards associated with sudden vehicle immobilization.
Owners seeking to confirm their vehicle’s status can visit Sernac’s official verification portal, where entering the VIN will determine if the PCM reprogramming is required. The process is designed to be straightforward, with no cost to the consumer and minimal downtime.
The alert reflects broader efforts by Chilean regulatory bodies to monitor vehicle safety standards and ensure timely responses to manufacturer-identified defects affecting consumer protection.
For ongoing updates, consumers are advised to consult Sernac’s website or contact the respective brand’s customer service directly. The agency will provide further information if additional models are found to be affected or if new developments arise regarding the defect’s scope or resolution.
