2006 Buick Lucerne Engine Problems

The car cuts off whwn you're driving it without warning. I have had the crankshaft position sensor replaced two times and it continues to fail. There are even reports in the internet that list this as a problem with this vehicle. I am afraid that someone will hit me from the rear and cause me injury or death. I am about to have this sensor replaced for a third time. It's absolutely ridiculous that I have to keep spending money out of my pocket for the same thing over and over again. This incident is a continual problem. It doesn't matter if you're stopped or driving it just happens out of the blue with no warning.

THIS 2006 LUCERNE ENGINE SHUTS OFF WHILE IN MOTION WITHOUT WARNING. IT HAS SHUT OFF FOUR TIMES THIS YEAR AND TWO TIMES LAST YEAR. THE LAST TIME IT SHUT OFF, WAS APRIL 11, 2017 5:00 PM CENTRAL STANDARD TIME ON A BUSY CITY STREET. MY WIFE IS NOT STRONG ENOUGH TO STEER THIS CAR WHEN THE ENGINE SHUTS DOWN. WHEN SHE HAD RESTARTED THE ENGINE SHE WAS SO NERVOUS UNTIL SHE ACCIDENTALLY TURNED THE WRONG WAY ONTO A BUSY BY-PASS.

4.6L NORTHSTAR ENGINE LEAKS OIL, AND WHEN DRIVING YOU CAN SMELL HOT/BURNING OIL, EVEN FROM INSIDE THE CAR. REALLY WORRIED THAT IT WILL CAUSE AN ENGINE FIRE.

ALUMINUM V8 ENGINE LEAKING OIL PROFUSELY. NOW GETTING SMOKE AND ODOR WHILE DRIVING. MY CONCERN IS THAT OIL IS LEAKING ON TO THE HOT EXHAUST MANIFOLD AND COULD POSSIBLY IGNITE. I SUSPECT ENGINE BOLTS NEED TO BE RETORQUED WHICH WOULD NECESSITATE ENGINE REMOVAL TO ACCOMPLISH. THIS IS A MAJOR DESIGN FLAW WHICH NEEDS CORRECTING. LEAKS OCCUR DURING ALL PHASES OF OPERATION. THE LEAKS FIRST BECAME EVIDENT SEVERAL YEARS AGO AND HAVE PROGRESSIVELY WORSENED SINCE.

MY 2006 BUICK LUCERNE ENGINES STOPS RANDOMLY. AS I AM TRAVELING DOWN THE ROAD THE ENGINE SUDDENLY CUT OFF AND THERE IS A LOSS OF ALL POWER STEERING AND BRAKES. ALL ELECTRICAL COMPONENTS BLACKS OUT AND WHEN IT STOPS YOU CAN NOT CRANK IT. AFTER WAITING DIFFERENT AMOUNTS OF TIME YOU CAN CRANK IT UP AND CONTINUES UNTIL THE NEXT MYSTERIOUS OUTAGE . THIS IS MY WIFE CAR AND I DO NOT ALLOW HER TO DRIVE IT. I DO NOT TAKE IT ON ANY WINDING ROADS. I WENT TO THE DEALERSHIP WHERE I PURCHASED AND WAS TOLD IF THERE IS NO CHECK ENGINE LIGHT THEN NO CODES WILL BE SET TO FIND THE PROBLEM. I HAVE CARRIED IT TO THREE OTHER SHOPS TO NO AVAIL. ONE MECHANICAL WAS DRIVING IT AROUND TOWN AND IT HAPPEN ON A ROUNDABOUT. HE SAID HE HAD TO STRUGGLE WITH ALL HIS MIGHT TO GET THOUGH IT BEFORE HE COULD STOP. I DO NOT KNOW WHAT TO DO AND HOPEFULLY NOTHING DREADFUL WILL HAPPEN, LIKE GM CARES. *TR

TOOK MY CAR INTO FIRESTONE AND FOUND OUT THAT THE MOTOR MOUNTS ARE SAGGING. MOST CARS ONLY NEED THE BOLTS ON THE MOUNTS REPLACE - THE LUCERNE IS THE ONLY ONE WHERE YOU NEED TO REPLACE ALL THE MOTOR MOUNTS BECAUSE THEY DON'T HAVE BOLTS IN THEM. ANOTHER FEW MILES AND I WILL HAVE AN ENGINE SITTING ON THE HIGHWAY. I AM EXTREMELY UPSET BECAUSE MY HUSBAND IS ALREADY HANDICAPPED AND WE BOUGHT THIS VEHICLE TO LAST FOR MORE THAN 150,00 MILES BEFORE WE HAD TO SINK THAT KIND OF MONEY IN IT. I HAVE HAD A SECOND OPINION AND IT IS INDEED A PROBLEM. *TR

I OWN AN '06 BUICK LUCERNE CXS WITH DEFECTIVE MOTOR MOUNTS. THESE MOTOR MOUNTS ARE KNOWN TO BE DEFECTIVE AND MANY BULLETINS HAVE BEEN POSTED, ALONG WITH MANY KNOWN CUSTOMERS GETTING THEM REPLACED. I HOWEVER HAVE HAD BAD LUCK GETTING MY LOCAL BUICK DEALERSHIP TO REPLACE THEM. THE PROBLEM HAPPENS WHILE TAKING OFF FROM A STOP. THE DEFECTIVE MOUNTS CAUSE THE ENGINE TO VIBRATE AND SHAKE THE CAR. THIS TO ME SEEMS LIKE A VERY DANGEROUS ISSUE TO HAVE TO DEAL WITH AND WOULD LIKE TO GET THESE MOUNTS REPLACED AS SOON AS POSSIBLE. *TR
