NHTSA lists 3 safety recalls and 22 owner complaints for the 2015 Scion TC. Most complaints involve power train (6) and air bags (5). The EPA rates it 26 mpg combined.
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain Toyota Racing Development (TRD) brake kits, part numbers PTR09-21111 and PTR09-52080, sold by Toyota as an optional accessory for model year 2008-2015 Scion xB, and 2011-2016 Scion tC vehicles.

Southeast Toyota Distributors, LLC (SET) is recalling certain model year 2016 Toyota Camry and Highlander, 2015-2016 Toyota Tundra, Scion FR-S, and tC vehicles. The Load Carrying Capacity Modification Label may not reflect the correct added weight of the installed accessories. As a result, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 110, "Tire Selection and Rims for Passenger Cars."
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2015 Toyota Scion tC vehicles manufactured December 3, 2014, to January 30, 2015 and equipped with accessory coil springs as part of an optional Release Series 9 trim package. During installation of these coil springs, the rear suspension components may not have been properly tightened.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“Whining noise is heard when the clutch petal is released. Noise is coming from the input shaft bearing. Common failure on this model. Mechanic confirmed that is the issue. If the bearing completely fails could leave the car stranded and cause more damage to other transmission components. No warning lights but noise is very loud.”
“The contact owns a 2015 Scion TC. The contact stated that the air bag warning light remained continuously illuminated while operating the vehicle. The contact stated that when the air bag warning light was illuminated, the horn was inoperable. The vehicle was not diagnosed or repaired. However, an independent mechanic informed the contact that the failure might be associated with an inoperable clockspring. The manufacturer was not notified of the failure. The approximate failure mileage was 130,000.”
“Over the past 4-5 years, 2015 scion tc has had numerous electrical issues. Both driver and passenger electric door locks do not work. Head and tail lamp lights burn out frequently. Seems like a grounding issue? Car failed to start August 2021 due to electrical problems. 3rd party mechanic fixed the issue. Toyota Dealer-installed automatic start fails multiple times before starting car. Basic electrical mechanisms for a car made in 2015 should not be broken/failing. 2019 Air Conditioner wouldn't drain. Had to investigate and personally drain the tubes behind the passenger and driver side-pannels behind center counsel. The entire draining system for the cars air conditioner had clogged. 2015 Exterior Vinyl Pillars on sides of windshield started to fade. Brought it to Westbury Toyota and they said the sun caused it. I didn't even have the car for 6 months yet....”
