I have a crimson red premium with the 20" wheels and tires. What a mistake. I drove the 18" version prior to getting mine and it was a floater. This one, equipped with RE97s rides like a go kart. And in sport mode it feels like you have no suspension at all. Now true, I'm a sporting sort of guy for an old geezer, but this car rides harder than a Vette or Z/28 that I've owned and its not in the same universe as my Pontiac G8 GT. At 500 miles I replaced the tires (at my expense) with Continental Extreme Contact DWS 06 and that helped a little. It still doesn't cure the issue that the suspension tuning is way off the charts. It's never still, never smooth. Going to the dealer service dept. tomorrow, but I highly doubt there's anything that can be done as it's just the way the car is. True, big wheels, but still a 40 series tire just like the 19s" on my G8. Why can the G8 ride light-years better on far more aggressive tires (RE-11s)? Other than the above, no complaints.
Update: I did take the car to the very helpful dealership because GM wouldn't talk to me unless I did. Checked out 'nothing wrong' and 'to spec'' as expected. I also got a chance to drive another new one with the 20" wheels and tires with the hyper-strut and adaptive damping. It was just as bad if not worse (as it had the OEM RE-97s). I've asked the service manager to run this up the ladder with GM regional service folks to see if we can get engineering to take notice. Hard to believe that they put this car out in the captured test fleet and this wasn't noticed, especially on Detroit streets.
Being retired, I was looking for a quite comfortable roomy car with easy to use controls and lots of safety features for my wife and me to use for travel. The Lacrosse fit the bill. I was impressed with all the safety features (love the heads up display) and the ease of use of the entertainment and navigation systems. Most luxury cars don't have touch screens, which to me was a distraction. The simpler the better. The trunk on the Lacrosse is huge so no problems getting luggage stowed. On the road the Lacrosse is very quiet and comfortable with plenty of power when you need it. I was impressed with the overall mileage on the first fill up at 29.4 mpg with a 200 mile trip to PA and the rest mixed driving. Some things I found troubling was there was no sunglass holder in the overhead (can use the space under the shifter, but still...), the visibility is not as good as I would have liked out the front when making turns and parking, and the transmission hunts a bit at low speed going up twisty hills. People complain about the electronic shifter, but I found it easy to use once I got used to it. Overall I find the Lacrosse to fit my needs just fine and look forward to many miles of comfortable quite travel.
Safety features are great-Automatic Vertical and parallel parking feature needs getting used to. Corrective steering is great when getting near edge of road or other lane. New shifting system is outstanding. Voice recognition features very improved along with Navigation system. Entertainment system/technology improved from my recent 4 Lacrosses. Turned in a 2014 premium Lacrosse and impressed with all the 2017 changes and new styling.
RIDE QUALITY IS HORRIBLE. BAD CONTINUOUS VIBRATIONS IN DRIVERS SEAT. TIRES POUND THE PAVEMENT. NO COMPARISON TO MY 2011 LACROSSE TRADE-IN. COMPLAINED TO DEALER. SHOWED SERVICE BUILLETIN #03-03-10-007J. TIRES GET A FLAT SPOT WHEN NOT BEING DRIVEN, AND SHOULD BE DRIVEN AT LEAST 15 MILES TO GET RID OF FLAT SPOTS. SUGGESTED BUYING NEW MICHELIN TIRES FOR $900.00.
Although the tires can be a bit noisy on some road surfaces, I love driving my LaCrosse. I've had it 8 weeks and still look for reasons to go driving. I got the Premium model because I wanted the safety alert seat among other standard features.
