Overview

• Summer assistance calls doubled over the last decade, rising from about 182,000 in 2014 to over 373,000 in 2024.
• Heatwaves boost mechanical and electrical failures by up to 50% and spark a 30% rise in nighttime interventions during ‘tropical nights’.
• Mechanical issues account for nearly 40% of summer callouts, followed by electrical faults (34%), tire problems (16%) and accidents (8%).
• High temperatures can cut electric vehicle range by as much as 20 km per day and increase battery-related assistance requests.
• Facing over 100 million summer journeys, the DGT has issued safety guidance and mandated pre-trip checks to curb heat-related breakdowns.
