Buick Electra E4 and E4 GS Ultium-based EVs introduced in China

China leads the way with Buick's revival, this month seeing the Trishield brand introduce another Ultium-based EV in two flavors for the Asian market. First comes the Electra E4, the crossover-coupe version of the Electra E5 that emerged from hiding in March. We know the formula — a little lower, a little shorter, a littler wider than the traditional sibling, with a steeper slope in the roof and a much faster backlight. The E4 wears a different front fascia design and touts subtle shifts like a single DRL instead of the dual DRLs on the E5. It goes a bit further with dual spoilers out back, a design trend found on decadent crossovers like the Aston Martin DBX and Genesis GV70 Coupe Concept.  The E4 is touch larger than our Buick Envision, the Chinese Electra about 7 inches longer, an inch wider, and 2.4 inches lower than the Envision, on a wheelbase 4 inches longer. The interiors hew to the design shown in the E5, with a bit more flash added. The same EYEMAX 30-inch, 6K curved screen forms the heart of the Buick Virtual Cockpit. The carmaker says front passengers get 39.9 inches of headroom in the E4, and there is "customer-pleasing headroom and knee space for second-row passengers," everyone bathed in light from the 12.9-square-foot low-radiation panoramic roof. It has 28 bins and cubbies for storage and 15.6 cubic feet of cargo room.  Underneath the skin, the entry-level powertrain has a 65-kWh lithium iron phosphate (LFP) battery powering a motor on the front axle making 241 horsepower and 243 pound-feet of torque. Based on China's test cycle, range is estimated at up to 329 miles. For now, the Electra E4 is only available with front-wheel drive.   Then there's the E4 GS, the first EV to merit Buick's Gran Sport designation. It's distinguished from the regular E4 with tweaks like a black diamond grille, black mirror caps, Night Bronze accents outside and in, 20-inch wheels hiding six-piston Brembo brakes on the front rotors, and illuminated sills. The GS starts with the same FWD drivetrain as the plain E4, but adds an AWD trim as well that's powered by a larger 79.7-kWh battery and makes 283 hp and 343 lb-ft. The front-driver can hit 62 miles per hour in 7.6 seconds. The AWD model cuts that sprint time to 6.2 seconds and increases range to an estimated 385 miles. Top speed for both drivetrains is 112 miles per hour.

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.

GM recalling 2013 Buick LaCrosse, Cadillac SRX over transmission software

The National Highway Traffic Safety Administration has issued recalls for the 2013 Buick LaCrosse and 2013 Cadillac SRX due to a problem with the software for the transmission controller. On about 27,000 SRX and LaCrosse models, the transmission could accidentally be shifted to Sport mode, which would reduce the amount of engine braking drivers experience.
NHTSA says this could increase the risk of a crash, but, fortunately, the required fix is simply an update to the software.
While we're on the subject of General Motors vehicle recalls, a small number (48) of compressed natural gas versions of the 2011 Chevrolet Express are also being recalled for a potential risk of fire or explosion. Yikes. Both official recall notices are posted below.
