Cadillac has confirmed that a suspension failure caused Valtteri Bottas’s heavy crash at the 2026 Mexico City Grand Prix and revealed that corrective measures have already been introduced ahead of this weekend’s São Paulo race. Team principal Marcin Budkowski provided the update following the American outfit’s investigation into the accident, which brought Sunday’s race to a halt.
The incident occurred when the front-left suspension of Bottas’s MAC-26 failed as he approached the first corner at the Autódromo Hermanos Rodríguez, leaving the Finnish driver unable to control the car before it struck the barriers.
Cadillac implements measures after investigating Bottas crash
Budkowski confirmed the findings in Cadillac’s preview of the São Paulo Grand Prix, explaining that the team had acted following its investigation.
“Following our post-race investigations, Valtteri suffered a suspension failure and we have implemented mitigations going forward,” the Cadillac team principal said.
The statement confirms the general cause of the accident but does not identify which component failed or explain the measures introduced.
Cadillac has also not disclosed whether the problem was related to a manufacturing defect, component fatigue, structural damage or another technical factor.
The team will return to the track at Interlagos on Friday, when it can evaluate the reliability of its cars under competitive conditions.
Bottas escapes injury after heavy impact in Mexico
Bottas was approaching Turn 1 at high speed when the front-left suspension failed, sending the Cadillac into the barriers.
Race Control initially deployed the Safety Car before stopping the race with a red flag to allow marshals to remove the damaged car and repair the barriers.
The Finnish driver remained in the cockpit briefly after the impact but was able to leave the car without assistance.
He subsequently underwent precautionary examinations at the circuit’s medical centre and was released without injury.
“It was a big impact going into Turn 1, but thankfully I’m okay,” Bottas said in Cadillac’s post-race statement.
The driver thanked the medical personnel and acknowledged the importance of understanding the failure before returning to competition.
The accident interrupted the Mexican Grand Prix and required a red flag.
Cadillac faces reliability questions after difficult debut season
The failure represents another setback for Cadillac during its first Formula 1 campaign.
The American manufacturer has experienced a series of reliability and operational problems throughout 2026, affecting both Bottas and teammate Sergio Pérez.
Pérez also suffered a suspension-related failure at the Canadian Grand Prix earlier in the season, although Cadillac has not established a technical connection between the two incidents.
In Mexico, the team demonstrated improved competitiveness but was unable to convert its pace into championship points.
Pérez reached 13th during the race before pit-stop equipment problems and a subsequent penalty compromised his result.
The Mexican explained how those setbacks affected his 300th Formula 1 start.
Budkowski believes the performance nevertheless demonstrated that Cadillac is making progress relative to its direct competitors.
Bottas prepares for Brazil amid uncertainty over 2027
The São Paulo Grand Prix also arrives at an important moment in Bottas’s career.
Cadillac has extended Pérez’s contract through at least 2029, but the team has not confirmed whether Bottas will remain in its race line-up next season.
Colton Herta is among the drivers being considered for a future opportunity with the American manufacturer.
The former IndyCar driver will replace Pérez during Friday’s opening practice session at Interlagos, seeking the final point required for an FIA Formula 1 super licence.
Herta’s appearance could remove a major obstacle to his Formula 1 ambitions.
For Bottas, the immediate priority is returning to competition after the heavy accident and helping Cadillac capitalise on its improved pace.
Friday’s opening practice begins at 12:30 BRT, followed by the second session at 16:00.
