Railway
31wheelsets showed outward wheel movement before a Washington Metro derailment.
The problems accumulated from 2017 through October 2021. The NTSB found that the operator had not conducted the trend analysis needed to evaluate whether its mitigations were effective. Findings published in 2024.
Automotive
About 4.8 millionvehicles were recalled because cruise control might not disengage.
NHTSA advised owners of affected Fiat Chrysler vehicles to stop using cruise control until repairs were completed. U.S., May 2018.
Automotive
362,758vehicles were recalled over driver-assistance behavior that could violate traffic rules.
Tesla’s FSD Beta could mishandle certain intersections, speed limits and lane changes, increasing collision risk without driver intervention. The remedy was a software update. U.S., February 2023.
Nuclear
€1.5 billionwas added to a reactor’s construction estimate following weld-repair requirements.
EDF revised the Flamanville EPR budget after France’s nuclear regulator required repairs to eight noncompliant containment-penetration welds. October 2019 estimate, expressed in 2015 euros and excluding interim interest.
Nuclear
2nuclear reactors were permanently retired after replacement steam generators developed premature wear.
San Onofre Units 2 and 3 closed in 2013. According to the operator’s account of NRC findings, flawed computer modeling had underestimated conditions that caused tube vibration, wear and leakage.
Nuclear
2reactor-safety reports were rejected as too incomplete for detailed technical review.
Oklo’s accident-analysis and licensing-methodology reports left unresolved gaps involving uncertainty, design margins and safety analysis. The NRC rejected the reports without prejudice, allowing future submissions. U.S., January 2022.
Batteries and energy storage
About 1.9 millionsmartphones were recalled, including replacement phones issued after an earlier recall.
The Samsung Galaxy Note7 recall expanded after additional incidents involving replacement devices. The batteries could overheat and catch fire. U.S., October 2016.
Batteries and energy storage
6model years of Chevrolet Bolt EVs were covered by a battery-fire recall.
GM identified two manufacturing defects that could coexist in one battery cell: a torn anode tab and a folded separator. The recall covered 2017–2022 Bolt EVs and 2022 Bolt EUVs.
Batteries and energy storage
About 34,460battery-expansion modules and cables were recalled over overheating connections.
Connections between Goal Zero Yeti Link modules and EC8 cables could melt, creating fire and burn hazards. U.S., June 2024.
Batteries and energy storage
About 5,740portable power stations were recalled because their batteries could overheat.
The HALO 1000 recall addressed fire and burn hazards associated with its lithium-ion batteries. U.S., August 2024.
Energy systems and power electronics
Approximately 1,200 megawattsof solar generation were lost during a grid disturbance.
NERC attributed the largest share of the loss to inverters calculating grid frequency incorrectly and shutting off their output. The findings prompted an industry alert in June 2017.
Energy systems and power electronics
About 1.4 millionelectrical panels were recalled over overheating and fire risks.
The affected Schneider Electric Square D breaker boxes were installed in homes and commercial premises. U.S., June 2022.
Energy systems and power electronics
About 2,600solar inverters were recalled because component failures could eject their covers.
Failing capacitors could cause heat buildup and force the enclosure cover off, creating fire and impact hazards. Eltek solar inverters, U.S., February 2019.
Energy systems and power electronics
About 6,500power stations were recalled because emergency-power mode created a shock hazard.
The Predator 2000-Watt units had reversed AC outlet wiring when operating in emergency-power-supply mode. Harbor Freight Tools, U.S., July 2025.
