On the 2006-2011 Hyundai Elantra, the anti-lock brake (ABS) hydraulic control module stays electrically energized even after the car is shut off. Over time, moisture can intrude into the module's circuit board and create a slowly developing electrical short. Because the circuit is live with the key off, the short can ignite an engine-compartment fire while the vehicle is parked and unattended. Hyundai opened the investigation after a 2007 Elantra fire showed blown fuses inside the ABS module.
Covered by NHTSA recall 20V061000 (Hyundai recall 188). The remedy installs a new relay in the main junction box that de-energizes the ABS module when the ignition is off, eliminating the key-off short-circuit path. Owners were advised to park outside and away from structures until the relay was installed. Repair is free at any Hyundai dealer.
On the 2007-2020 Hyundai Elantra, on the Elantra's inline-4 (Beta II 2.0L in 2007-2010, Nu 2.0L in 2011+), P0171 means fuel trims have gone too positive because unmetered air is entering the engine. The classic Elantra trigger is a vacuum leak — most often a hardened/cracked PCV hose or a leaking intake-manifold gasket — followed by a contaminated mass-air-flow (MAF) sensor giving low airflow readings, or a stuck-open purge/PCV valve. A weak fuel pump or clogged injectors are less common but possible when fuel pressure drops below the ~49-53 PSI spec. Being an inline-4, the Elantra has only Bank 1, so this is the only lean-bank code it can set.
Perform a smoke test to pinpoint the vacuum/intake leak, then replace the failed PCV hose, intake-manifold gasket, or PCV valve. Clean the MAF sensor with MAF-safe cleaner (or replace if it doesn't recover). Verify fuel pressure holds 49-53 PSI to rule out a weak pump or clogged filter/injectors. Clear codes and re-check long-term fuel trims (should return toward 0%).
