GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.

Buick really wants us to know the new Cascada convertible won't leak

Quality testing on the factory floor is nothing to joke about. Automakers need to make sure the work being done is up to snuff, and that means some extensive checks. For Buick, that means using a lot of water for each of its Cascada convertibles. Each vehicle that rolls off the floor is subject to a high-pressure, ten-minute soaking that sprays nearly 20 gallons of water from each nozzle during every bath, just to guarantee the fabric roof hasn't sprung any leaks. For some reason, Buick has chosen to show off this testing with the help of what we imagine is the Gorton's Fisherman's baby cousin. Check out the strange testing video, available up top.

Spy photos of the upcoming Buick Regal wagon, via the Opel Insignia

We're pretty sure Buick is working on a Regal wagon. And because the Regal is the Opel Insignia on the other side of the pond, these spy photos show us what's in store when it eventually turns into a Buick. The rakish wagon was lightly camouflaged, giving us our best look at the upcoming vehicle. The wagon shares a lot of the same design cues as the Insignia sedan that we spotted earlier. The bottom of the front end is covered in heavy camouflage, masking the wagon's grille. It's unsure to tell whether the black nostril-like pieces sitting above the grille are vents or just tape. The prototype still shares the same upright nose as the model we spotted earlier, giving the wagon a wider stance than its predecessor. The side profile of the wagon is sleeker, thanks to the extra four inches between the axles, than the current model is, with the design mimicking that of a shooting brake instead of a traditional wagon. The rear end of the wagon is also more upright with the taillights and bottom part of the fender jutting out beyond the glass. The boxy design sitting atop of the rear end doesn't match the rest of the vehicle and appears to be a part of the car's camouflage. With the tunnel-like design at the top gone, the rear end would have a more streamlined design. With the next Regal expected to continue on as a rebadged Insignia, the likelihood of a Regal Wagon in the US look good, but aren't set in stone. Late last year, Buick filed two trademarks for "Tourx" and "Regal Tourx," pointing towards a high-riding wagon with all-wheel drive. Imagine these spy shots with a taller suspension and some crossover-inspired trim pieces and you have a wagon that could take on the likes of the Subaru Outback and Audi Allroad.
