I have difficulty when locking/unlocking my vehicle with my remote key fob and main look system from all doors of the vehicle. When the lock/unlock button is pushed on the vehicle's two front doors the driver's side door does not lock with the other doors on the vehicle. The driver side door is the only door that malfunctions all other doors operate efficiently. This locking malfunction occurs…

What stands out
Owners have filed 47 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA electrical complaint has been filed on this vehicle in over 7 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2014 Corolla has serious infotainment system failures around 70,000 miles (after warranty expires) that cost $1,000–$3,600 to fix, and power door locks fail prematurely on multiple doors; safety concerns include unresponsive touchscreens preventing hands-free calling, fires in electrical wiring, brake failure paired with unintended acceleration, and airbag non-deployment during frontal collision.
Owners report three main electrical failures on 2014 Corollas: infotainment system crashes, door lock actuator failures, and miscellaneous electrical fires or faults.
Infotainment System Reboot Loops: The premium Entune navigation/radio unit enters endless reboot cycles, showing a loading bar that never completes. The screen flashes on and off while driving, creating dangerous distraction, especially at night. All functions fail—navigation, Bluetooth hands-free calling, radio, USB, and auxiliary input stop working. This typically occurs around 70,000 miles, right when the three-year warranty expires. Owners cite a Fujitsu component defect; Toyota later switched to Panasonic units. Replacement costs range $1,000–$3,600. Hard resets and battery disconnects don't help. Owners report this as widespread across 2014–2016 models and reference TSB 0172.16, though Toyota claims warranty expiration voids coverage.
Door Lock Actuator Failures: Multiple door lock actuators fail within short timeframes and low mileages (28,000–51,000 miles). Locks don't respond to key fob or door buttons, requiring manual locking. Some doors intermittently fail; others fail completely. Repair costs exceed $1,400 for multiple actuators. Owners cite online reports of widespread failures across Toyota models and mention law firms investigating the defect.
Electrical Fires and Wiring Faults: One owner reported fire originating in the dashboard; another saw smoking from the fog light when activated. A rear window defroster wiring harness burned near the tail light. A wiring harness fire also occurred during parking. One owner experienced brake failure paired with sudden unintended acceleration after shifting to Drive in a parking garage, resulting in a collision.
Other Electrical Issues: Touchscreen unresponsiveness in lower corners, headlight low-beam failures, a faulty eco boost light fixture, loss of power to stereo/clock/dome lights/keyless entry/power locks, seatbelt locking issues, and airbag non-deployment during a frontal collision despite an active recall (20TA03).

I have a 2014 corolla and out of the blue with in the last few days my entire screen for my audio and navigation went blank on my car. It goes between running a process and then back to a black screen. It's a safety issue because it's very distracting for one, and for two I got the upgraded navigation so I had hands free. I'm very dissatisfied and when looking it up have seen several complaints…

My car was parked in my driveway when an electrical fire ignited. I was unaware and a neighbor knocked to let me know the car was smoking. The fire department responded swiftly and determined the fire was electrical and originated in the dash and had burned the entire dash, the fire was limited to this area and did not extend to the engine of the vehicle.
