Open the full vehicle complaint log (all categories)The contact owns a 2009 Acura TSX. The contact stated while driving at an undisclosed speed, the check engine warning light illuminated, after which the vehicle entered LIMP Mode and the throttle failed to respond. The contact was able to pull to the shoulder of the roadway to restart the vehicle. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a persistent failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 143,000.
VEHICLE HAS THROWN AN ENGINE CODE DUE TO EXCESS OIL CONSUMPTION DUE TO STICKY PISTON RINGS, ADVANCEMENT IN TIMING AND VVT ADVANCEMENTS. DUE TO THIS ENGINE CODE BEING THROWN, THE CAR DEACTIVATES VSA AND ALSO THROWS AN EMISSION CONTROL LIGHT. THIS CAUSES THE CAR TO ENTER A STATE WHERE IT ADVANCES THE RPM'S AT IDLE BY A SIGNIFICANT AMOUNT AND BURNS MORE FUEL. WHEN LEAVING THE CAR IN DRIVE BUT AT A STOP, THE CAR WILL QUICKLY ACCELERATE NEARLY TO 30 MPH ON A FLAT SURFACE. IN ORDER TO STOP THE CAR, THE DRIVER MUST EXCESSIVELY ENGAGE THE BRAKES. ACURA TECHNICIANS HAVE INFORMED ME THAT THIS IS A KNOWN ISSUE AND IS DUE TO THE PISTON SEALS BEING FAULTY, CAUSING EXCESSIVE OIL CONSUMPTION AND LOOSING THE TIMING CHAIN TO BECOME OUT OF SYNC. ENGINE WILL THEN ENTER A "LIMP" MODE WHERE CAR WILL IDLE HIGHER, BURN MORE FUEL.
MY 09 ACURA TSX PINGS WHENEVER YOU MODERATELY OR HEAVILY STEP ON THE GAS. ACURA/HONDA KNOWS THIS IS A WIDESPREAD ISSUE AND NEEDS TO FIX IT. THIS IS PREMATURELY WEARING ENGINE COMPONENTS OUT. MY CAR CURRENTLY HAS 78,000 MILES ON IT. NOT ACCEPTABLE! *TR
