My experience at 4800 miles is 18 to 20 mpg in mixed city and and highway driving and 24 to 28 on the highway. Experience is about 5 to 7 mpg less than window sticker if drive in econ mode and staying in green zone. Difference in DIC and actual is DIC overstates actual by .5 to 1.5 MPG. This is less than the Lexus and Camry V6 mileage. Lexus and Camry yield sticker mpg plus.
 
Buick could put in Toyota's 4 cyl conventional engines and increase mileage and not have to have loss of trunk room and hard downshifts.
 
Most people I have talked to with the eAssist are disappointed in fuel economy. Buick field engineers had my car for two days and said everything checked out OK. Over $1000 warranty and roadside assistance so far. None of my Lexus or Camrys ever had any warranty.

I thought they had a minimal warranty of 36000 miles since they are perfect.
 
May I suggest you go buy a toyota camry or lexus model, whatever floats your boat. And if you name means you actually worked for GM, I suggest respectfully you ask toyota for retirement checks and your social security and medicare.
 
All you have to do is trade your Buick and you're done. End of file.

Odd, my 2012 w/V6 is around those numbers.
 
There was mention on another forum of a poster who was getting lower than normal E-assist mileage, but then also many reports of upper 30s on the highway.

We have a 2010 CXL with the 3.0L V-6 initially offered in Lacrosse, but only for 2010, after the I-4 was programmed to allow for e-assist with the 3.6L V-6 being an exta option. The 3.0L was used in some Cadillac models and achieved very good MPG. We get 18-20 in city and 29-30 max at 65-70 MPH with two adults luggage and full loads of crap for the grandkids on regular fuel - not premium like many riceburners. For a VERY heavy car that is great on the road we are not unhappy with the MPG at all. We opted to avoid the nav, sunroof, 19" wheels and AWD that added $ and complexity. The midpriced CXL had the leather electric seats that we wanted and the other options are very friendly. Great car so far.

Good afternoon td77,
 
Were you and your dealership able to work out a resolution on your LaCrosse since your last post?
 
Best,

There is something wrong with your eAssist unless you drive VERY aggressively. I have a 2011 Lacrosse with the 2.4 DI engine (no eAssist) and average 24mpg (tracked at 23.9 over 11,000 miles on fuelly.com). I drive pretty hard. These engines need to rev to make power and I spend a great deal of time between 2,500 and 3,500 rpms in city driving and drive 70 to 74 mph on the highway.
 
I get 20mpg city and 29 hwy with ease.
