On the 2015-2020 Alfa Romeo 4C 1.75L Turbo I4, the Alfa TCT (Twin Clutch Transmission) develops shudder and hesitation at low speeds, particularly during parking maneuvers and stop-and-go traffic. The dry dual-clutch design wears faster under frequent low-speed use.
Common Symptoms
- Low-speed shudder
- Hesitation from standstill
- Jerky parking maneuvers
- Transmission warning light
How to Fix
Perform a TCT clutch adaptation reset using Alfa Romeo diagnostic software (WiTech). If shudder persists after adaptation, the clutch pack assembly requires replacement.
On the 2015-2020 Alfa Romeo 4C 1.75L Turbo I4, the front and rear suspension bushings wear prematurely due to the stiff suspension setup and lightweight construction. Track use accelerates wear significantly, causing clunks and wandering.
Common Symptoms

- Imprecise steering feel
- Uneven tire wear
- Wandering at highway speeds
How to Fix
Replace worn bushings with polyurethane or spherical upgrades for improved longevity. Perform a full alignment after bushing replacement. Track-focused owners should inspect bushings every 10,000 miles.
