Guatemala is nearing the launch of ethanol-blended gasoline sales, but authorities haven’t established a clear process for handling consumer complaints. Currently, no specific protocol exists to address potential vehicle damage linked to the new fuel blend. DIACCO, the consumer protection agency, intends to utilize existing procedures, but requires a technical assessment from the Ministry of Energy and Mines (MEM) to resolve any complaints. This lack of a defined responsibility framework raises concerns about accountability and consumer recourse. The absence of a streamlined process could lead to delays and difficulties for vehicle owners experiencing issues. Officials are working to clarify the protocol before the fuel becomes widely available. This situation highlights potential regulatory gaps in the implementation of the ethanol blend.
