Perez wants answers after bizarre Cadillac suspension collapse

Sergio Perez did not try to hide his concern after Cadillac’s Canadian Grand Prix descended from strategic frustration into outright mechanical embarrassment, with the Mexican driver demanding answers following a shocking suspension failure that abruptly destroyed his race in Montreal.

The incident was as strange as it was alarming.

Running deep in the pack after a risky tyre gamble backfired early on, Perez was approaching the pitlane at reduced speed when the front-right suspension on his Cadillac suddenly folded underneath the car.

As carbon fibre bits scattered across the pit entry road, the car sagged helplessly to one side, and Perez’s afternoon was instantly over.

What made the moment even more unsettling was the absence of any obvious trigger. No wall strike. No aggressive kerb hit. Just a complete structural failure at low speed – precisely the kind of problem Formula 1 teams and drivers fear most.

And Perez made it clear afterward that Cadillac cannot afford to shrug this one off.

“It’s something that we have to understand and get on top of, because it’s not ideal what is happening and has happened,” he said.

“It’s something we need to investigate and hopefully get on top of, because it’s not ideal. I think, operationally, we are still lacking a lot, and we are not making the progress that we are making in terms of performance.

“So we need to be able to maximise the car performance at the moment.”

A race that had already slipped away

Long before the suspension collapsed, Perez’s race had already become a survival exercise.

Cadillac rolled the dice by starting on intermediate tyres while much of the field committed to slicks — a decision that rapidly unravelled as the track conditions improved faster than expected. The intermediates overheated within laps, leaving Perez stranded and forced into recovery mode almost immediately.

“It was honestly 50:50 at that point,” Perez explained. “At that point, I felt like it had stopped raining a bit less, but it became a lot clearer that we were on the wrong tyre very early on.

“Within three laps, we killed them, and that was the biggest issue there. But we managed to recover.”

Despite the strategic setback, Perez had begun clawing his way back into contention. Running 16th, he was locked in battle with Esteban Ocon’s Haas and had started to find a rhythm before the car gave up beneath him.

“We had some good pace out there, some good fights with the Haas. We overtook the Haas, and unfortunately, we had a suspension failure at the end.”

Perez’s comments hinted at something deeper than one unlucky retirement.

The Mexican’s frustration centered not just on the failure itself, but on what he sees as a troubling disconnect inside Cadillac’s operation: gains in outright speed are not being matched by execution and reliability.

That is a dangerous imbalance for any Formula 1 team – especially one still trying to establish credibility in the midfield fight.

Mechanical failures can happen. But suspension collapses without contact are rare, highly scrutinized, and impossible to ignore.

And Perez, a veteran who has seen championship-winning standards up close, sounded very much like a driver losing patience with problems that should not exist at this level.
