The failure pattern owners describe
The 2005 Tucson has a severe electrical problem that manifests in multiple ways. Most serious: engine dies without warning at any speed, from idle to 70 mph on freeways. Owners have been forced onto highway shoulders without power steering, stalled in traffic during rush hour, and had near-miss incidents with trucks. Dealers replace ignition components, EVAP valves, coil packs, and spark plugs—sometimes multiple times—but the stalling returns. No diagnostic codes appear in many cases, and one dealer claimed they couldn't hook up a computer without replacing it first.
Door locks malfunction independently, locking and unlocking randomly whether the engine runs or not. One owner got trapped inside; another had to crawl through the passenger side. Dealerships have reprogrammed affected vehicles seven or more times without fixing it.
A chronic no-start condition affects some owners weekly, requiring jump-starts each time, despite normal battery, starter, and alternator tests. One owner jump-started the vehicle 35+ times over ownership.
Other electrical failures reported: horn doesn't sound despite six dealer visits and replacement of the horn, conjunction box, and modulator; power windows in three doors quit within a week of each other; door handles break off; and one owner reported an electrical fire in a parked vehicle. One car also accelerated on its own while in park, reaching 25 mph without throttle input.
