A stuck wheel nut cost Valtteri Bottas his Brazilian Grand Prix before the lights went out. Coming a week after a suspension failure sent him into the barriers in Mexico, it adds to a troubling sequence. Cadillac’s own explanations make this harder to dismiss as bad luck.
Valtteri Bottas never got the chance to make a mistake in Brazil. His race was over before the start because Cadillac couldn’t remove a right-rear wheel nut.
A week earlier, a suspension failure had sent him into the barriers in Mexico. Two different problems, two lost races, and one driver left relying on his team to put things right.
Brazil Brought an Unwelcome Monaco Reminder
Cadillac team principal Marcin Budkowski confirmed that a cross-threaded wheel nut prevented Bottas from starting at Interlagos. The team’s efforts to free it came to nothing.
For Bottas, there was an obvious memory: Monaco 2021. Running second for Mercedes, he stopped for tires and never rejoined. The wheel gun had stripped the gripping surfaces of the front-right nut, leaving the crew unable to remove the wheel.
Different teams, different wheels and different described failures. The familiar part was the helplessness. Once again, Bottas couldn’t drive his way out of the problem.
But the more concerning comparison was with the previous Sunday.
Mexico’s Explanation Raises Bigger Questions
Bottas’s front-left suspension failed approaching Turn 1 in Mexico, sending his Cadillac into the barriers. He avoided serious injury, although his right leg struck the steering wheel during the impact.
Before Brazil, he explained that brake heat had affected the suspension mountings. Cadillac reverted to older components and lowered its operating temperature limits.
“We thought it was safe, but we never tested by running it so long at that temperature,” Bottas told The Race.
That is the detail that gives this story weight. Cadillac identified the cause and acted, but a component’s limits had been exposed through a high-speed failure with a driver aboard.
Brazil’s wheel-nut problem wasn’t a recurrence of that suspension fault. It was another failure arriving immediately after a far more serious one.
The Problems Extend Beyond Bottas
Sergio Pérez also lost time to a slow stop in Brazil, which he believed involved the same issue encountered in Mexico.
“We need to make sure we fix our tools and get everything right,” he said in Cadillac’s postrace comments.
Building an F1 team takes time. Cadillac deserves room to develop its pace. Its drivers also deserve reliable equipment and race operations that give them a chance to compete.
Mexico required a safety fix. Brazil requires an operational answer. Both demand follow-through.
Bottas can fight for positions in a slow car. He cannot compensate for suspension that fails or a wheel that won’t come off. Before Cadillac asks more of its drivers, it needs to give them more reason to trust that their work will count.
