2020-2026 CUPRA Formentor Problems: 13 Known Issues

Owners of 1.4 TSI e-Hybrid Formentors have reported a high-voltage battery-management fault in which the car shows a 'drivetrain error, take to workshop' warning and the dealer's diagnosis finds that the battery is not reporting its state of charge or temperature, values the original poster described as safety critical. In the SEATCUPRA.NET thread, the original poster's car developed the fault at about a month old in 2021 and spent seven weeks at the dealer before the owner was offered termination of the finance agreement; another member reported the same issue on a week-old car in March 2022. This is an owner-reported pattern, not a published manufacturer bulletin.

Owners of the Formentor e-Hybrid report the charging-socket flap on the left front wing refusing to pop open, which stops them plugging in, or no longer staying shut. Some describe it only in frost, when the release pin freezes; one owner had a warranty repair of the flap actuator authorised and another had a broken plastic part in the flap replaced under warranty. It affects only the Formentor e-Hybrid (1.4 TSI plug-in hybrid, 204 or 245 PS); petrol-only cars have no charging flap. Owner reports cover model-year 2022 cars and a VZ e-Hybrid 245 at its third service.

Owners report the keyless (touch) door handles working only some of the time or showing a keyless error, and an SOS emergency-call fault warning appearing on the dash, sometimes with loss of connectivity. It affects Formentor models with keyless entry and the SOS emergency-call system; owner reports cover 2020-2023 cars. The reports describe fault warnings, not calls placed by the car.

Owners of the Formentor e-Hybrid report the 12V battery running down after the car stands for a few days, leaving it dead or showing low-battery, SOS and Travel Assist warnings, even with the high-voltage battery charged. Causes owners were given vary: a standby function not switching off, a door not fully shut, and a charging fault. It affects the Formentor e-Hybrid (1.4 TSI plug-in hybrid, 204 or 245 PS). The linked owner reports involve 2021-2022 cars; none of them cover 2023-2024 cars or petrol-only Formentors.

Owners report "Manoeuvre braking currently unavailable" and "Park Distance Control: please clear sensors" warnings at start-up, with front or rear sensors disabled even when clean. One owner sees it on hot, sunny days and another in winter; causes owners were given include a single faulty sensor, a stone-chipped sensor and software. It affects Formentor models with parking sensors and Manoeuvre Braking; owner reports cover 2021-2023 cars. The cause varies from car to car. Mileage when it happened, as stated in the linked owner reports: 380 miles.

The rear left wheel bearing housing (wheel carrier) on affected cars may fail early and break. CUPRA's recall notice says these parts were made with air cavities; a break could impair the car's stability and increase the risk of an accident. It affects CUPRA Formentor (type KM) cars built between 31 March and 20 April 2023, covered by CUPRA recall 42M7 (EU Safety Gate alert A12/01881/23, notified by Germany). The notice does not limit it to one engine or trim. Only a CUPRA dealer can confirm whether a specific VIN is included and whether the work has been done.

Owners of Formentors with Dynamic Chassis Control (DCC) adaptive dampers report a clunk or rattle from the front suspension over speed bumps and broken surfaces; owners disagree on whether Comfort or Cupra mode makes it worse. In a SEATCUPRA.NET thread, owners attribute the noise to the Monroe DCC front dampers, whose internal electrically controlled valves are thought to make the noise; cars built in April 2022 and May 2023 are reported, and members report the same clunk on the Leon ST, Golf 8 R and Audi Q3 with DCC. Dealers greasing suspension components gave only temporary relief. This is an owner-reported pattern, not a manufacturer bulletin.

An official recall (EU/UK) covers Formentors built October 2020 to March 2022 fitted with the electromechanical brake servo and DSG gearbox. A heat-protection mat was incorrectly fitted at the factory, allowing engine-bay heat to melt the brake fluid reservoir and cause brake fluid to leak into the engine compartment. This is a safety-critical defect because loss of brake fluid degrades braking performance, and leaked fluid in a hot engine bay is a fire/contamination risk. Roughly 2,499 vehicles were cited in the UK action.

Owners report a "parking brake fault" message, sometimes followed by hill-start assist or Travel Assist warnings, shortly after the ignition is switched on. In one linked report the message cleared once the engine was running; in the other, Auto Hold and hill-start assist also stopped working, and the owner's garage fixed it by replacing the parking brake button. One owner was told by another member that it is logged as a stored fault when a gear is selected very quickly at start-up. It affects Formentor models with the electronic parking brake; owner reports cover a 2020 petrol car and a car whose year is not stated. Whether a warning reflects a real brake fault has to be confirmed by diagnosis.

Owners report "Gearbox error" warnings with the DSG automatic dropping into an emergency mode that holds low gears at high revs, jerking when a gear is selected from rest, or noise on every gear change. Repairs owners describe include a replaced mechatronic control unit after fault P175E00 (clutch 1) and, on an e-Hybrid, a replaced dual clutch. It affects Formentor models with a DSG automatic. Owner reports cover a 2.0 TSI 190 4Drive that was about six weeks old in August 2022, a 2021 1.5 TSI FWD and the e-Hybrid with its six-speed DSG, including a model-year 23/24 VZ e-Hybrid 245. These reports do not involve manual-gearbox cars. Mileage when it happened, as stated in the linked owner reports: 1,300 miles and 28,000 km (about 17,400 miles).

The engine mounts on affected cars can break. The recall notice says this affects driving stability and creates a risk of an accident. It affects CUPRA Formentor (type KM) cars built between 26 July and 7 August 2023, covered by CUPRA recall 10J3 (EU Safety Gate alert A12/02690/23, notified by Germany; the same alert covers the CUPRA Leon). The notice does not limit it to one engine or trim. Only a CUPRA dealer can confirm whether a specific VIN is included and whether the work has been done.

Australian recall REC-006608, reported by CarExpert on 13 May 2026, covers specified VINs among 2024–2026 Ateca, Leon, Formentor and Terramar vehicles. The report lists 920 affected vehicles across those models. Under certain driving conditions a software issue can temporarily disable power assistance. Steering remains functional, but increased effort, especially when cornering, increases crash risk. Check the individual Formentor VIN; the model-year range alone does not establish inclusion.

Owners report the central touchscreen lagging, freezing, going black while driving and rebooting, or failing to wake until the next restart. Some report the problems continuing after updates. It affects pre-facelift Formentor models with the original central touchscreen (built before the April 2024 facelift); owner reports cover cars from 2020-2023, including early-VIN cars that needed a dealer-only update. These reports do not cover the facelift.
