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.

Junkyard Gem: 1962 Buick LeSabre 2-Door Sport Coupe

American car shoppers looking for a full-sized hardtop coupe in 1962 couldn't go wrong with the offerings from The General. Chevrolet would sell you a snazzy new Bel Air sport coupe for just $2,561 (about $23,800 today), but those Joneses next door wouldn't have felt properly shamed if you put a new proletariat-grade Chevy in your driveway. No, to really stand tall during the era of Alfred Sloan's Ladder of Success, you had to go higher up on the GM food chain. For the B-platform full-sized cars of 1962, that meant the Pontiac Catalina/Bonneville beat the Chevy, the Oldsmobile 88 was the next step up the ladder, and at the very top was the Buick: the hot-rod Invicta and its swanky LeSabre sibling. To go beyond that, you had to move up to a C-platform Buick Electra or Cadillac. Today's Junkyard Gem is a once-luxurious '62 LeSabre, now much-faded in a northeastern Colorado boneyard. The reason GM shoppers got so bent out of shape about the "Chevymobile" episodes of the late 1970s, in which some GM cars received engines made by "lesser" GM divisions, was that each division had its own family of V8 engines during the 1950s and 1960s and they weren't supposed to be mingled. The '62 LeSabre got a 401-cubic-inch (6.5-liter) Nailhead engine (so called because the valves were unusually small), rated at 265, 280, or 325 (depending on what kind of compression ratio and carburetion you wanted). That's not crazy horses for a big-displacement, two-ton luxury coupe of its era, but the small valves allowed for combustion chambers optimized for one thing: low-rpm torque. This 401 has the two-barrel carburetor, so it made either 412 or 425 pound-feet of torque. That's just a bit less than the mighty Cadillac's engine that year, and definitely sufficient to get this car moving very quickly. You had to pay a fat premium on the Chevrolet, Pontiac, and Oldsmobile B-bodies to get an automatic transmission (a three-speed column-shift manual was base equipment in those cars), but a Turbine-Drive (formerly known as the Dyna-Flow) automatic was standard issue on the 1962 LeSabre. This was an interesting transmission design that traced its origins back to the 1942 M18 Hellcat Tank Destroyer and used torque-converter multiplication to provide a CVT-like experience with no perceptible shifts (the driver could select a separate low gearset manually, so the shifter looks just like the one on the true two-speed Powerglide transmission).

2019 Buick Regal TourX sells better than expected, has brand's wealthiest buyers

Being a wagon fan in America is tough, since it seems everyone prefers the higher ride heights and SUV looks of crossovers. But today we have some good news for wagon fans via Buick. Apparently the 2019 Buick Regal TourX is popular with well-heeled buyers, and it's been selling quite a bit better than Buick expected. A representative from Buick revealed that Regal TourX buyers have the highest average income of any of the brand's products. He even noted that TourX buyers' average income is higher than the Buick Enclave Avenir, the extra-plush variant of the three-row crossover and the most expensive vehicle in Buick's lineup. To put the price difference into perspective, the most expensive Regal TourX starts at $35,995, while the Enclave Avenir starts at $54,695. Besides selling to people of some means, the Regal TourX has proven to be more popular than Buick expected. Buick's representative said that initial estimates were that the wagon would make up about 25% of sales, but it's actually making up about 40% right now. Buick has sold 3,408 Regals in total this year, so that means about 1,400 of them were TourX wagons. That number doesn't quite translate over all of 2018 since the TourX was released a little later and the supply was still ramping up through the year. As such sales were closer to 3,000 out of a little over 14,000 for the whole year, or somewhere above 20%. But the increased percentage from the model's release is still impressive. Granted, sales still favor crossovers. Buick's least popular crossover, the Envision, sold about twice as many units as all Regals last quarter. Yet, we count this as good news on the wagon front. Better still, the TourX's top rival, the Subaru Outback, has moved 76,000 units so far this year. Times may be tough for the wagon fan, but there are still some small wins to celebrate. UPDATE: The estimate of Regal TourX numbers for 2018 was higher than actual sales as the TourX was launched later than all Regal models, and the supply wasn't up to full steam for the whole year. The corrected number is now in the text. Related Video:
