“Estimados, Mi nombre es [XXX] , residente de Toa Baja, Puerto Rico. Soy propietario de un Lexus IS250 2010, VIN [XXX] . Recientemente acudí a un concesionario Lexus para solicitar evaluación del deterioro del tablero y paneles interiores (superficies pegajosas y agrietadas). El concesionario negó la asistencia indicando que la lectura actual del odómetro no coincide con la última registrada en su sistema. Deseo aclarar que el problema del tablero y paneles es un defecto de material ampliamente documentado y no guarda relación con el millaje del vehículo. Por tal razón, solicito respetuosamente que mi caso sea evaluado por Lexus Corporate bajo criterios de asistencia voluntaria o buena voluntad, independientemente de la discrepancia del odómetro. Agradeceré la revisión de este caso y orientación sobre los próximos pasos. Att [XXX] Toa Baja, Puerto Rico Tel. [XXX]”

“WHEN THE BRAKES ARE APPLIED WHILE IN DRIVE THE RPMS RANDOMLY INCREASE FROM 500 TO 1000 AND THE CAR INCHES UP UNLESS I APPLY MORE PRESSURE ON THE BRAKES. THIS IS USUALLY NOTICEABLE WHILE I AM IN THE DRIVE-THRU AT FAST FOOD RESTAURANTS WHILE WAITING IN LINE. WHILE WAITING FOR 5 OR SO MINUTES IT USUALLY OCCURS 2-3 TIMES. I RARELY NOTICE IT HAPPEN AT TRAFFIC LIGHTS AS THEY USUALLY DON'T LAST THAT LONG. IT HAPPENS AT LEAST A FEW TIMES A WEEK.”
