#1 of 17 2012 Buick LaCrosse E-Assist
Nov 25, 2011 (6:45 pm)
Considering the purchase of a 2012 Buick LaCrosse with E-Assist. Every option available for a V6 is available for this car except the push button start and EZ Access! Why would Buick leave out such a basic convenience? Nicely configured E-Assist vehicles seem to be in short supply!

My first 2,359 miles were suburban driving, and I average 23.8 mpg. Yesterday I took a 755 mile trip speed limit + 10 mph and average 29.4 mpg. I'm curious as to what my mileage would be at 70 mph.
#5 of 17 does eAssist offer enough power?

Don't mean to be rude but am just wondering if 4 cylinders plus eAssist has what it takes to move a car as heavy as the LaCrosse. I mean accelerating from a stop, going up long hills, getting it done in cut & thrust thruway passing.

I drive a 2011 Lacrosse with the 4-cyl (No e-assist) that is the same engine used in the 2012 e-assist minus the electric motor. It has plenty of power for me. I do not drive at higher elevations or fully loaded though. My typical driving is at 400 to 1000 feet above sea level (Iowa, Illinois, Wisconsin) with a 400lb payload.
An owner who regularly drives at higher elevations and/or carries 3-4 people + cargo would be better served by the V6. The 2.4L DI engine in my car is a quick revver that will spin past 4,000rpm very quickly and makes good power while doing it. It has never felt under-powered to me. It does generate 182HP at 6,000rpm and has a 7,000rpm redline, delivers 23-24mpg in mixed driving, and is installed in very nice car with a smooth shifting 6-speed automatic transmission.

I have discovered that I miscalculated my mileage on the 755 mile trip. It was actually 32.2 mpg... and then 33.3 mpg on my return trip. Not too shabby for 10 mph over the posted speed limit.
#9 of 17 Charging System Drain after 100 miles new purchase

Hello, after 100 miles on a new Eassist the vehicles charging system drained, resulting in a service engine soon light as well as a battery charging light. Vehicle made it back to dealer but shut down its eassist functionality. Dealer claims a full battery recharge should do the trick. we'll see....

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.
