The failure pattern owners describe
Owners report a wide range of electrical failures in 2017 Tucson models. The most serious allegations involve engine fires—several owners describe flames under the hood, burning smells from the engine bay, and scorched wiring harnesses, often following recall repairs or during normal driving. Multiple owners report their vehicles stalling or losing power on highways without warning lights, sometimes at highway speeds, and some describe the car refusing to turn off or restarting unexpectedly.
Dashboard electrical anomalies are common: all warning lights illuminating simultaneously, speedometer failing to work, instrument cluster going dark mid-drive, and false or random sensor warnings. Owners describe hesitation on acceleration, rough idle, and RPM issues tied to electrical system failures or knock sensor updates that allegedly trap vehicles in limp mode at 45 mph.
Door latches malfunction frequently—rear doors locking owners inside or refusing to open from either side, and front doors requiring extreme force or becoming inoperable from external handles. Window controls fail, sometimes operating one direction only. Push-button start systems occasionally fail to turn engines off.
Backup camera blackouts, radio resets, and Bluetooth/infotainment glitches appear regularly. One owner alleges cyber hacking of the vehicle's systems. Brake light wiring scorches repeatedly; headlights fail frequently. Some owners report multiple bulb burnouts in short timeframes.
Anti-theft concerns emerge: vehicles lacking immobilizers are stolen easily by targeting the steering column, and some describe remote-start or smart-key button failures. One owner reports extreme oil consumption requiring checks every 1,000–3,000 miles despite no visible leaks.
