Yes, my Buick was an early 2010 model. I saw a picture in a magazine and finally replaced our old '97 Riviera, which is still on the road, btw, being driven by our gardner's mom. I read that GM halted production on the new Lacrosses for quality purposes. I didn't read why. The noise on start-up with the new engine is a 30/40 second series of vibration sounds at different tones. My local dealer will look at it next week. Maybe something simple, though nothing about this disappointing turn events has been simple.

My last conversation with GM Customer Assistance did not end well and they did not address my questions or concerns. I probably won't be speaking to GM Customer Assistance again. They had no answers for what to do with my bad Buick other than to become a regular at the local service department. Forgive me if I'm being pessimistic but I no longer trust that car. After the engine blew up on a busy freeway, I can't help but ask myself what's next?

Although you may not know, did the 97 Riviera ride and handle as nice as the Aurora? How would you compare to Lacrosse?
I had 96 Aurora and find that everything else disappoints in the ride and handling catagories. I have to attribute it to the very different design of suspension components. I have often heard the Riviera of that time was the same in 2 door version but with different powertrain.
One unique thing was the power steering rack with tie rods. It was one solid cast steel rod so any movement from center would actually gently tug the lower end of each front strut off center. Very unique.
Do you feel the vibrations or just hear them? Are they high pitched or low? Make sure you note as much as possible and point out to service so they don't miss anything. Mis-diagnosis could result in many trips.

Wow, I'm no expert like you. I just know we loved that Riviera. Had some problems with the transmission, which had to be replaced, but all in all, a joy to drive and ride in. Plus, it was really beautiful. I have to say I would choose the Riv over the Lacrosse, but the CXS we bought is mighty close. And it runs on regular, which my supercharged Riv did not.
I recorded the vibration noise this morning. I'm calling it a vibration noise because it sounds a little like my Samsung washer, but also a buzz saw. I figure something isn't getting oil pumped up to it for a minute or so. Maybe the recording will help the service people, though they shouldn't have a problem hearing it. Just noise so far. Maybe something needs to be tightened.

Dealer ordered ONE new sensor, the other side is apparently OK. I need to go back for a repair in a few days once the part arrives.
The system started to work all by itself yesterday.
Electronics are NOT the dealer's strong suit.

I think with the sudden increase in the number and type of electronic/computer geegaws in most of todays cars, all dealers of all makes are going to be severely challenged in diagnosing and fixing problems. It's like dealing with a corporate IT department when things go wrong with your office computer. Not good.

No surprise, Lacrosse sales down by 12% in May -- but why?
Buick was the strongest of the GM brands, posting a 24% improvement over May 2011 as the “affordable luxury brand” moved 15,579 cars and SUVs.
The three models that returned from last year (Enclave, LaCrosse, Lucerne) all posted negative growth in May but the sporty new Buick Regal helped the brand show the big growth numbers with 4,247 sedans sold.
The LaCrosse was the top seller with 4,774 units sold (although it was a decline in growth of 12%) followed by the Enclave with 4,323 SUVs sold

I hope it is something simple and not detrimental.
I would sample oil and make sure you did not get a bad filter like I did.
There are a lot of recommendations for Blackstone Labratories.

Perhaps it is marketing strategy.
High gas prices and high unemployment certainly effect buying choices.
I suspect many might find the I4 not quite enough for this vehicle, and the upcharge for the 3.6L might be a turnoff.
If prospects are learning that premium is recommended for 3.6L, that could certainly hurt since most will avoid the additional 30+ cents per gallon.
I had an I4 in Malibu and it was peppy enough in it. I did try premium a few times but it did not give the boost I see in 3.6L.
Also, what is on lots? What I've seen is that most that have just a few options always add a pricey sunroof.
And incentives may be poor at this time.

Thx rainman5542 for info. I'm taking mine in tomorrow.
Was your trouble easily located thru electronic diagnosis?
Are the sensors under the the rear side panels? And the electronics accessed thru trunk or are they under front hood squeezed in with other stuff?
I wonder how prevalent this problem is. Beings it's a SAFETY item I'm surprised there's not more notoriety.
