# Honda Struggles to Identify Root Cause of Lance Stroll's Battery Failures Aston Martin faces a critical reliability crisis as Lance Stroll records his 13th retirement. - **Source:** [Motorsport.com – F1](https://www.motorsport.com/f1) - **Published:** 2026-11-10 - **Topic:** [sports](https://brifing.si/c/sports) - **Original article:** - **On Brifing:** https://brifing.si/s/b9307037-c61e-4069-94fc-2da6b610bd2c ## Recurring Battery Failures Lance Stroll suffered his 13th retirement of the 2026 Formula 1 season during the Brazilian Grand Prix at Interlagos. The Canadian driver was forced to retire after 30 laps due to a persistent battery issue. This latest failure highlights a troubling trend for the Aston Martin team throughout the current campaign. ## Honda Seeks Root Cause Honda trackside general manager Shintaro Orihara confirmed that the team understands the technical symptoms but lacks the root cause. Engineers are currently analyzing data and the physical battery unit to diagnose the error. Orihara noted that identifying the underlying trigger could take several weeks of intensive investigation and testing. ## Historical Reliability Context Stroll is now only one retirement away from matching the all-time Formula 1 record of 14 DNFs in a single season. This unwanted milestone was previously set by Andrea de Cesaris in 1986 and 1987, and later matched by Rubens Barrichello in 1997. The frequency of these failures remains a major concern. ## Management Frustration Mounts Reports indicate that team owner Lawrence Stroll is increasingly frustrated by the team's endless reliability problems. Discussions regarding the future direction of the project have intensified, with questions raised about potential personnel changes or new strategic ideas. The team faces significant pressure to resolve these systemic issues before next season. ## Performance Deficits Persist Beyond the battery failures, the AMR26 continues to struggle with power output and energy recovery system efficiency. While rain at Interlagos temporarily masked some performance weaknesses, Fernando Alonso finished 12th, outside the points. The team must address these fundamental drivability issues to remain competitive against the rest of the field. ## Vibration and Wear Factors Earlier this season, engine vibrations caused significant damage to battery packs, preventing the car from completing full race distances. While recent issues appear distinct from those early mechanical failures, engineers are struggling to determine if current problems relate to total mileage or specific operational points during high-intensity race conditions. ## Urgent Need for Countermeasures Honda emphasizes that finding a definitive solution is critical for the 2027 season. Without identifying the root cause, the team risks repeating these failures next year. The engineering team is prioritizing the development of robust countermeasures based on the data collected from recent race weekends to ensure future operational stability. ## Future Development Outlook The team must now balance immediate race-to-race fixes with long-term design improvements for the upcoming car. With the season nearing its conclusion, the focus shifts entirely toward rectifying these technical gremlins. The ability to stabilize the power unit will determine whether Aston Martin can recover its competitive standing next year. ## Sources covering this story - [Motorsport.com – F1 — Honda Struggles to Identify Root Cause of Lance Stroll's Battery Failures](https://www.motorsport.com/f1/news/honda-struggling-to-explain-lance-strolls-13th-dnf-of-the-season/10873412/?utm_source=RSS&utm_medium=referral&utm_campaign=RSS-F1&utm_term=News&utm_content=www) - [Source — Aston Martin F1 Team Faces Critical Reliability Crisis](https://www.crash.net/f1/news/1110073/1/martin-brundle-reveals-f1-team-boss-wits-end-over-reliability-issues) - [The Race — Honda Faces Persistent Reliability Crisis in Formula 1](https://www.the-race.com/formula-1/honda-f1-new-reliability-problem-might-not-cure-before-2026-end/) --- _Summary written by Brifing from the original reporting.
