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.

[UPDATE] Cadillac Blackwing gets ticket to Italy, to go to work in a supercar

UPDATE: It seems MAT's belief it had secured a supply of Cadillac's 4.2-liter Blackwing V8 was premature, and based on a handshake deal before GM sold its Turin engine center to Italy's Punch Group. Shortly after Hagerty ran the story, GM sent a statement to the outlet reading, in part, "We do not have an agreement in place with Manifattura Automobili Torino (MAT) to provide or sell the Blackwing engine. ... Our team is following up with MAT president Paolo Garella to discuss the misunderstanding." MAT also submitted a statement to Hagerty, saying, in part, "We thank GM for the clarification. Although a signed agreement was not finalized between the parties, we were under the impression that our counterpart was committing to making this engine available to MAT at conditions yet to be defined. ... We hope that this misunderstanding will not compromise our relations with GM and possible future collaborations." The original article follows: Some necessary cost-cutting at Cadillac led to switching the new CT4, CT5, and Escalade to older platforms. The revised architecture plan meant Cadillac's newest top-tier products couldn't fit Cadillac's newest top-tier engine, the 4.2-liter twin-turbo DOHC V8 known as Blackwing. That engine would serve limited duty at full power in the now-dead CT6-V, and at reduced output in the CT6 Platinum V8 trim before ending its bright, brief domestic life. But the story isn't over, the rebirth of Blackwing coming from a most surprising locale: Turin, Italy. Before the canceled Geneva Motor Show, Hagerty spoke to Paolo Garella, CEO of Manifattura Automobili Torino; that's the company better known as MAT, makers of the New Stratos and contract engineering house for boutique screamers like the Aspark Owl electric hypercar, Apollo Intensa Emozione, and SCG003C. Garella told the outlet, "We have an agreement with General Motors" for a supply of Blackwings, which would be developed and built at the General Motors Propulsion Engineering Center (PEC) in Turin. Since 2005, the PEC has been used to develop GM's global diesel engines and electronics. MAT's plan is to put the V8 into a new limited-run car MAT is creating from its own design. Then another surprising turn: Belgium-based global auto supplier Punch Group bought the PEC, with plans to work with GM on projects in progress until at least the end of 2021. Nothing changes as far as MAT is concerned, except perhaps a chance for an even closer collaboration with Punch Turin.

2024 Porsche Panamera; Rivian's surprise; Cadillac electrifies V | Autoblog Podcast #823

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Associate Editor Byron Hurd. They start off discussing a couple of vehicles they've both driven — the 2024 Ford Maverick Tremor and the 2024 Volvo C40 Recharge 2WD. From there, they pivot to Byron's first drive of the 2024 Porsche Panamera, and then from there it's on to more electrified luxury in the form of the new Cadillac Lyriq. After that, it's on to news. Rivian made a big splash last week. Not to be upstaged, Cadillac decided to get in on the action by teasing an electric V model, the Opulent Velocity Concept. After that, it's time for a future classic; this week, it's the Dodge Magnum. They end the episode by spending listener Isaiah's money on some used stick-shift transportation.  Send us your questions for the Mailbag and Spend My Money at: Podcast@Autoblog.com.
