1999 Hyundai Elantra recalls

VEHICLE DESCRIPTION: SOME SONATA VEHICLES EQUIPPED WITH 2.5 LITER V-6 ENGINES AND ALL ELANTRA MODEL VEHICLES MAY HAVE EXPERIENCED INTERMITTENT LOW-SPEED ENGINE STALLING, WHICH COULD OCCUR IF THE MAF (MASS AIR FLOW) SENSOR ELECTRICAL SIGNAL IS INTERRUPTED AS A RESULT OF ENGINE VIBRATION TRANSMITTED TO THE MAF SENSOR CONNECTOR WIRING HARNESS.

Risk: THIS CONDITION CAN CAUSE THE ENGINE TO STALL, INCREASING THE RISK OF A CRASH.

Remedy: DEALERS WILL RE-ROUTE THE MAF SENSOR CONNECTOR WIRING HARNESS.

VEHICLE DESCRIPTION: PASSENGER VEHICLES EQUIPPED WITH AUTOMATIC TRANSMISSIONS. THE AUTOMATIC TRANSMISSION PRESSURE CONTROL SOLENOID VALVE SEALS DO NOT REMAIN SUFFICIENTLY ELASTIC, RESULTING IN TRANSMISSION FLUID LEAKAGE. THIS LEAKAGE CAN RESULT IN REDUCED PRESSURE APPLICATION TO THE CLUTCHES, BRAKE, AND KICKDOWN SERVO, ALLOWING THEM TO SLIP.

Risk: SUCH SLIPPAGE CAN CAUSE PREMATURE DETERIORATION OF THE FRICTION ELEMENT SURFACES AND COULD CAUSE THE VEHICLE NOT TO ACCELERATE, OR NOT ACCELERATE AS EXPECTED, WHEN THE DRIVER PRESSES THE ACCELERATOR PEDAL.

Remedy: DEALERS WILL REPLACE THE PRESSURE CONTROL SOLENOID VALVE.
