VEHICLE SPEED CONTROL
Description:WAS DRIVING MY INFINITI Q50 ON A NORMAL DRY DAY WHEN ALL OF A SUDDEN IT DOWN SHIFTED OR FELT LIKE I WAS DRIVING A STANDARD MODEL VS AUTOMATIC... I PULL OVER MY ENGINE LIGHT COMES ON.. I TURNED OFF ALL SENSORS ASSOCIATED WITH THE INTELLITOUCH SYSTEM THINKING IT WAS NOT JUDGING THE DISTANCE CORRECTLY BETWEEN CARS BECAUSE IT WILL AUTOMATICALLY SLOW YOUR CAR DOWN... CONTINUED DRIVING AND I'M NOTICING AS I TRY TO ACCELERATE MY CAR IS NOT SHIFTING INTO 3RD GEAR... SO I GET TO ABOUT 35-40 MPH AND NOW I CAN TELL IT'S REVVING IN THE SAME GEAR..GET HOME GOOGLE THE ISSUE AND IT SEEMS THE VALVE BODY ON THE 2015 Q50 HAS A THREAD... GO TO YOUTUBE THIS GUY HAS A VIDEO ABOUT HIM BEING TOLD IT'S THE SPEED SENSORS... BUT WHEN HE WENT FOR REPAIR INFINITI INFORMS HIM THE VALVE BODY NEEDS REPLACING. I TOOK MY CAR INTO AN INFINITI DEALER , SPENT $180 TO HAVE A DIAGNOSTIC RUN AND WAS TOLD THEIR IS A SERVICE BULLETIN FOR THE SPEED SENSORS THAT THEY SHOULD JUST REPLACE THE VALVE BODY. THE VALVE BODY IS $1635 A
