Brake servo and vacuum pump Fiat: problems by model and engine

Documented faults, from most to least important

Severity × frequency. Below each one, the Fiat models it appears in.

- Critical severityFrequency: OccasionalFiat Doblò IIBrake servo vacuum hose connector that can break (2012 Doblò)Fiat recalled Doblòs (and other models from the brand, such as the Qubo) built between June and September 2012 because a connector on the brake servo hose could fail and cause the vacuum assistance to be lost, forcing you to press the pedal harder. It is corrected by fitting a new hose.
- Critical severityFrequency: OccasionalFiat QuboBrake servo vacuum pipe connector that may break (2012 Qubo)Fiat recalled Qubos built between June and September 2012 because a brake servo pipe connector could fail and cause a loss of vacuum assistance, meaning more effort on the pedal. The campaign (DVSA R/2012/139) is resolved by fitting a new pipe.
- High severityFrequency: OccasionalFiat CinquecentoLoss of brake servo assistance after prolonged high-speed drivingYes: in 1997 Fiat recalled the Cinquecento built between November 1996 and April 1997 because, after long periods at high speed, the brake servo could lose assistance due to contamination of the diaphragm with petrol. The vacuum hose is replaced and the brake servo's effectiveness is checked.
- High severityFrequency: OccasionalFiat Doblò IIBrake servo vacuum pump that may not work properly (late 2019 Doblò)In January 2020 Fiat recalled (UK) Doblòs built between 24 October and 5 December 2019 because the brake vacuum pump might not work properly. The remedy is to replace the pump; the register consulted does not detail the specific risk or the cause.
- High severityFrequency: RareFiat Punto IIIBrake recall campaigns: brake servo connectors and handbrake (2013)In 2013, Fiat recalled Punto cars over the brake servo connectors (February) and over a handbrake fault on around 1,000 cars (4 December), in two independent campaigns.
