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: 1972 Buick Centurion Four-Door Hardtop

During the mid-to-late 1960s, General Motors made flashy, semi-sporty versions of each of its full-sized B-body cars. Oldsobile had the Delta 88 Royale, for example, while Pontiac offered the Grand Prix. The rakish big Buick of that period was the Wildcat, built through the 1970 model year. Just as the Wildcat shoved aside the Invicta, the Centurion appeared in 1971 to replace the Wildcat. Named after a famous 1956 concept car, production of the Centurion continued just through 1973. Just over 100,000 were built, and here's one of those rarities in a Colorado self-service boneyard. The Centurion was available as a hardtop coupe, a convertible, and a four-door hardtop sedan. It was at heart a LeSabre with a different grille and other cosmetic touches. Instead of the usual triple-shield Buick emblems, the Centurion got Roman-soldier badges. Perhaps the world's best-known Centurion is the '72 convertible driven by Kurt Russel's slimy-car-salesman character in the 1980 film, Used Cars. Kurt ends up selling his Centurion to a customer he "baited" from the rival lot across the street. In 1974, the Centurion was replaced by the LeSabre Luxus, a trim-level designation that Buick swiped from Opel. The only engine available in the 1971 and 1972 Centurion was Buick's 455-cubic-inch (7.5-liter) V8, renowned for its low-rpm torque. Power numbers for 1972 dropped considerably compared to 1971, mostly due to the switch from gross to net measurements that year; the base '72 Centurion 455 was rated at 225 horsepower and 360 pound-feet, while an optional higher-compression version with dual exhaust made 270 hp and 390 pound-feet. All Centurions came off the assembly line with three-speed automatic transmissions. For 1973, a Buick 350 (5.7-liter) V8 became standard Centurion equipment, with the 455 an extra-cost option. The original buyer of this Centurion probably regretted the single-digit fuel economy of the 455 when OPEC shut off the oil taps in October of 1973. Front Range Colorado isn't particularly rusty, but this car looks like it must have spent some time in a road-salty place like Wisconsin or Iowa. There isn't much left of the padded vinyl roof, standard equipment on all Centurion sedans and coupes. It would have been prohibitively expensive to make this car nice again, so here it sits. This radio played AM and 8-track tapes and cost $363 extra on a $4,508 car (that's $2,615 and $32,485 in inflation-adjusted 2022 dollars).

GM announces 3 new recalls affecting 1.7M vehicles in North America [w/video]

Still embroiled in the ongoing ignition switch recall, General Motors announced today three more discrete recalls, affecting a grand total of 1,546,900 vehicles in the US. The Detroit News reports that some 1.7 million vehicles are affected overall in North America. The first and largest of the trio of new recalls concerns some 1.18-million Buick Enclave and GMC Acadia crossovers from the 2008-2013 model years, Chevrolet Traverse from 2009-2013 (pictured above) and Saturn Outlook vehicles from 2008-2010. All of the crossover utilities may have an issue with the wiring harness for their seat-mounted side airbags. Apparently, the vehicles are equipped with a Service Air Bag warning light that, if ignored, "will eventually result in the non-deployment of the side impact restraints." Those restraints include the side airbags, a front-center airbag if the vehicle is so equipped and seatbelt pretensioners. Dealers of affected vehicles will be instructed to remove driver and passenger side airbag wiring harness connectors, and then "splice and solder the wires together." The second recall affects 303,000 Chevrolet Express (pictured right) and GMC Savana vans from model years 2009-2014, and with gross vehicle weights under 10,000 pounds. Said vehicles do not comply with a head impact requirement for unrestrained occupants, and will need a reworking of the instrument panel material to be sent back on the road. It doesn't sound as though there's a quick fix for this one, as the GM press release states: "Unsold vehicles have been placed on a stop delivery until development of the solution has been completed and parts are available." Finally, the third recall affects 63,900 Cadillac XTS luxury sedans from model years 2013 and 2014. A brake booster pump may be susceptible to corrosion by way of the relay, potentially causing and electrical short, overheating, melting of plastic components and even engine fires. GM says it is aware of two engine fires in unsold XTS models and two cases of melted parts. Repairs for the issues affecting the XTS have not not mentioned by GM in the release. The Detroit News is also reporting that along with news of the triple-recall, GM is taking a $300-million credit to help pay for the repair costs, and to deal with the ongoing costs associated with the ignition switch recall. In an attempt to explain just what GM has been doing in the face of these very serious issues, newly minted CEO Mary Barra has addressed the issues in a new video.
