Fernando Alonso reported total loss of sensitivity in his hands and feet during Grande Prêmio of The team abandoned the first two races of the 2026 season without completing the full distance, with Alonso retiring on lap 32 in Xangai after experiencing extreme discomfort. The FIA analyzes telemetry data to assess whether the car poses a risk to the safety of drivers, which could result in restrictions or even exclusion from the next stage in Suzuka.
The problem arises from overload in the MGU-K, an energy recovery component, which generates oscillations transmitted to the chassis, seats and pedals. Essas vibrations affect not only performance, but mainly the physical condition of pilots, with reports of prolonged numbness. The Aston Martin-Honda partnership, which began in 2026, has faced difficulties since pre-season testing, when battery failures were already limiting track time.
Intense vibrations in Xangai
Alonso described that, from lap 20 onwards, he began to lose feeling in his extremities. Ele took his hands off the steering wheel in several straights to ease the discomfort.
The driver only completed part of the race before abandoning, citing that there was no reason to continue in the last positions. Stroll also retired early, due to battery failure.

The regulatory body thoroughly examines the information collected from the two cars. The priority is to ensure that pilots do not suffer permanent damage.
If vibrations are not contained, measures such as limiting engine speed or prohibiting participation may be applied. The investigation takes place before the Japão GP, scheduled for the end of March.
Challenges of technical partnership
The Honda power unit exhibits low-frequency oscillations that damage hybrid components. The team has introduced countermeasures to protect the battery, but rider comfort remains compromised.
Adrian Stroll indicated an even lower limit, around 15 laps.
Expected progress on Suzuka
Honda works to reduce vibrations at the source, focusing on the internal combustion engine and the MGU-K. The Japanese manufacturer confirms advances in the system, but admits that rider comfort requires urgent attention.
The Japão GP represents Honda’s home race, which increases the pressure to resolve the issue. The team plans a meeting with the automaker to discuss definitive solutions.
Previous reports of Alonso
The driver had already criticized Honda power units in 2015, during his time at McLaren, comparing them to engines from lower categories. Agora, in Aston Martin, faces similar difficulties with excessive vibrations.
The situation reinforces the need for quick adjustments to avoid worsening risks. The FIA maintains constant supervision over telemetry data sent by teams.
Health risks for pilots
The oscillations transmit repetitive forces to the hands and feet, which can cause neurological damage in prolonged exposure. The team monitors physical limits to avoid irreversible injuries.
Interim measures include reducing laps in sessions and adjustments to the car’s setup. The focus remains on identifying the root cause for effective fixes.
The problem affects the progress of the season, with zero conclusions in the first stages. Aston Martin seeks to stabilize the operation to compete under safe conditions.
