SEAT Leon ST (2014–)

What's good

Same 5 Star Euro NCAP rating as for Leon hatchback: 94% adult protection, 92% child protection, 70% pedestrian protection, 71% safety assist.

What to watch out for

10-4-2018: Report that 23,000 miles 2013/63 SEAT Leon 1.4TSI ST has a fault code P334B/013131. This is the later design of actuator which does not have the vaccuum control pipes but is driven by the ECU. It appears that the shaft of the actuator has some lateral movement when hot which may be causing it to stick so various warning lights and problems ensue, to the point of loosing the turbo action. Car had been serviced at 8k by a SEAT dealer, at 13k by an independent dealer and at 22k by a local garage. The thing is, it looks as if the actuator has to be changed with the turbo. The way the system is designed, there is no ability to calibrate the actuator to the turbo as far as we can tell at the moment. Owner feels "this is a ridiculous piece of design and for it to have failed so soon and so expensively should not have happened." The question is, this must affect all other VAG cars with the same turbo actuator.

Recalls

4-11-2015: EA288 1.8TFSI and 2.0TFSI engines recalled in USA because the rear camshaft lobe is prone to unexpectedly shear off from the shaft. The failure causes reduced engine power and loss of vacuum pump power, cutting vacuum supply to the brake booster and eventually resulting in increased braking effort."A reduction in engine power and/or increased need for braking effort after vacuum reserve has been depleted while driving can increase the risk of a crash," a statement cautions. The campaign affects approximately 92,000 vehicles including the 2015-2016 Beetle, Beetle Convertible, Golf, Golf GTI, Golf SportWagen, Jetta and Passat. In notifying the National Highway Traffic Safety Administration, VAG stated that the root cause of the camshaft failures has not been fully understood. The company is still continuing an in-depth failure analysis and development of a repair solution, however a fix may not be ready until the end of the first quarter of 2016.
