NHTSA Complaint #10597087 — 2010 HONDA CIVIC

DAY1: I HAVE A 2010 HONDA CIVIC EX-L SEDAN WITH MILEAGE OF 95-100K. I WAS TRAVELING AT APPROXIMATELY 40-MPH (BEST GUESS-TIMATE), THE VEHICLE CHECK ENGINE LIGHT CAME ON, GREEN LIGHT NEXT TO DRIVE (D) BEGAN FLASHING AND VSA INDICATOR WAS LIT TOO; VEHICLE SEEMED TO BE A BIT JERKY SHIFTING. TOOK IT INTO HONDA AND THEY CHANGED TRANSMISSION FLUID, AS WELL AS REPLACED THE 3RD GEAR PRESSURE SWITCH. DAY 3: I EXPERIENCED A SIMILAR PROBLEM, WITH THE ADDITIONAL SYMPTOM OF THE SPEEDOMETER DISPLAY FLUCTUATING WILDLY / READING TOO LOW OR ZERO VALUES. THE LOCAL HONDA DEALERSHIP PERFORMED A COMPUTER UPDATE, CLEARED ERROR CODES, AND A 10-MIN TEST DRIVE DID NOT RECREATE THE ISSUE. DAY4: WHILE GENTLY ACCELERATING TO 45-MPH, MY CHECK ENGINE LIGHT APPEARED AND THE SPEEDOMETER ABRUPTLY DROPPED TO NEAR "ZERO". IT WAS AT THIS POINT THAT THE TRANSMISSION ABRUPTLY DOWN-SHIFTED TO EITHER 1ST OR 2ND GEAR AND CAUSED THE TIRES TO SCREECH (AS IF I HAD JAMMED ON THE BRAKES, BUT I HAD NOT). THE ABRUPT DECELERATION OF MY VEHICLE NEARLY CAUSED AN ACCIDENT WITH THE CAR BEHIND ME, WHO WAS ALSO ACCELERATING AND NARROWLY AVOIDED REAR-ENDING MY VEHICLE (I IMAGINE BECAUSE OF THE SUDDEN DECELERATION WITHOUT WARNING OF BRAKE LIGHTS). THIS TIME, BEFORE RETURNING TO DEALERSHIP, I PERFORMED ONLINE RESEARCH AND WHEN I DID RETURN TO THAT DEALERSHIP, I SUGGESTED THEY CHECK THE ENGINE'S SPEED SENSOR. SURE ENOUGH, THEY ENDED UP REPLACING THE SPEED SENSOR AND HAVEN'T HAD THE PROBLEM SINCE (3 WEEKS NOW). I'M REPORTING NOW BECAUSE OF MY CONCERN THIS MALFUNCTION COULD OCCUR TO SOMEONE ELSE AND CAUSE THEIR VEHICLE TO BE REAR-ENDED. *TR
