2006 Buick Lucerne Owner Comments

problem #6

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.

The contact owns a 2006 Buick Lucerne. The contact stated while driving 5 mph, the vehicle stalled. The vehicle successfully restarted within a few hours; however, the failure recurred intermittently. The vehicle was taken to an independent mechanic, but he could not diagnose the failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 85,000. The VIN was unavailable.

Since about 60,000 miles, the car it stalls out. It can stall going 70 mph down the interstate, stall at stop signs, stall pulling out of an intersection. Last occurrence I was trying to cross a major highway when it stalled. I coasted across the highway and it restarted right away. If a car had been coming from either direction, we would have been hit. I have had 4 sensors replaced and nothing seems to fix this problem.

The contact owns 2006 Buick Lucerne. The contact stated that the engine would violently shake. The contact took the vehicle to their mechanic and was informed that three of the four engine mounts needed to be replaced. The manufacturer was made aware of the failure, and the contact was informed that later model year vehicles were being repaired free of charge for the same failure. No reason was provided as to why the failure occurred. The vehicle was not repaired. The failure mileage was 74,000 and the current mileage was 80,000.

While driving the car looses all engine power and will just roll and this continues for up to 2-10 seconds. You do have ps, pb and all electric items the engine just falls to a idle.then the engine races for a few seconds when it recovers. You have no idea this is happen until you fell the car is not powering. We owned the car since new in 06. This happen several time when the car was new now 2.5 years latter it is starting this again. Buick has not been able to fix this issue. Milage on car is 42,000.

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.
