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.

Nearly half of Buick dealers choose buyout over investing to sell EVs

In 2022, General Motors gave Buick dealers across the nation a simple choice: invest a significant amount of money to prepare for EVs or opt for a buyout. Over a year later, the brand has reportedly lost nearly half of its dealerships as it prepares to roll out its first electric cars. Trade journal Automotive News reported that the number of Buick dealers in the United States dropped by about 47% during 2023. At the beginning of the year, the network included 1,958 stores; fast-forward to December and that figure stands at approximately 1,000. More dealers could throw in the towel in the coming weeks, as the publication adds that the buyout program remains open and will continue. Dollar figures haven't been released, so we don't know precisely how much money a dealer who opts out can claim from General Motors or how much money a dealer needs to spend to stick with the brand. However, the latter figure falls somewhere between $300,000 and $400,000, Automotive News learned. Dealers notably need to invest in equipment (such as charging stations) and training. Buick doesn't seem fazed by the exodus. "I'm really pleased with where we are. The network, where we are now, is a good size. It's with dealers who are focused on the business, who've shown that they can recover the volume that the dealers who transitioned away were doing," company boss Duncan Aldred said. According to Automotive News, the dealers who chose to stop selling Buick models accounted for about 20% of the brand's sales in the United States. Buick told the publication that around 89% of the American population still lives within 25 miles of one of its dealerships. General Motors extended the same offer to Cadillac dealerships in 2020, and about 150 stores allegedly chose to leave. For context, the dealer network consisted of 880 locations in the United States before executives floated the buyout offer. The dealers who left received between $300,000 to $500,000, the report adds, while preparing to sell electric cars would have set them back by around $200,000. Related video:

Audi tops Consumer Reports' brand rankings while Tesla leads domestics at eighth

Tesla supplanted General Motors' Buick division as the top-ranked US automaker in Consumer Reports annual brand rankings, though the electric-vehicle maker finished eighth among global automakers. Buick had finished atop CR's domestic car-brand list for three years before Tesla leapfrogged it. Scores were calculated from a combination of performance, owner satisfaction, and reliability. CR noted that Buick scored big on reliability but not so high on performance, while Tesla appeared to present the opposite case. Volkswagen's Audi division repeated as the best overall brand for the second straight year, beating out VW's Porsche unit, BMW, Toyota's Lexus division, and Subaru. Kia and Mazda followed those brands, while Honda finished ninth, between Tesla and Buick. Consumer Reports took results from 31 brands. Reliability issues related to the Toyota Tacoma helped drop that Japanese automaker out of the top 10. Take a look at CR's results for its Annual Brand Report Card here. That Tesla, Audi, and Porsche placed so high is topical, given some of the issues plaguing those automakers. Audi, Porsche, and their parent VW have been coping with the effects of the diesel-emissions scandal that broke back in 2015. The scandal has cost Europe's largest automaker billions of dollars, and forced VW to put a stop-sale on diesel-powered cars in the US in late 2015. And while the Tesla Model S improved from the "worse-than-average" label CR gave it in its 2015 Annual Auto Reliability Survey, the problematic falcon-wing doors on the Tesla Model X SUV pulled that model's reliability scores lower last year. Additionally, the Model X's climate-control system and door locks have also caused issues. Toyota and Lexus finished atop CR's reliability rankings last year. Related Video:
