2015 Chevy Silverado, GMC Sierra recalled for steering issues

DETROIT — General Motors Co is recalling more than 1 million pickup trucks and sport utility vehicles in the United States due to issues with a temporary loss of power steering, the National Highway Traffic Safety Administration said. The recall is for 2015 models. They are: the Chevy Silverado 1500, Suburban and Tahoe, GMC Sierra 1500, Yukon and Yukon XL and Cadillac Escalade. The problem may cause difficulty steering the vehicle, especially at low speeds, increasing the risk of a crash, the auto safety regulator said in a document dated Sept. 12. The document did not highlight any reports of accidents and injuries, because of the power steering issue. GM dealers will update the power steering module software, free of charge for owners of the affected vehicles. In 2014, the No.1 U.S. automaker had recalled nearly 800,000 pickup trucks worldwide because of the same problem. GM did not immediately respond to a request for comment.Related Video:

Hotter Cadillac CT4-V prototype spied testing at GM's Proving Grounds

Cadillac already teased us once with the hotter CT4-V and CT5-V at the Belle Isle Grand Prix, but these photos are still the best look yet at what's next for the Cadillac V-Series. The car we're looking at in heavy camouflage here is a high-performance CT4, but we don't really have a name to call it at this point. Cadillac hasn't said, so it could be anything. We'll just refer to it as the faster V, as it's certainly looking a bit more racy than the warmed-over CT4-V already revealed. While the styling isn't drastically different from the CT4-V already out there, the front intake and openings look deeper and more aggressive. The middle, raised section of the hood is a little taller and the whole front-end design looks a lot like the one teased in Belle Isle. This vehicle even appears to have the same mirror design as the faster V. The side sills, quad exhaust tips and wide rear tires lend this prototype an aggressive look, but we did note that it doesn't have the big ducktail spoiler we saw teased previously. Maybe Cadillac is trying to keep a low profile while testing. A keen eye will notice a wild apparatus attached to the front, which would serve as a great jousting pole if you were into that kind of thing. We don't know exactly when Cadillac plans to introduce the faster V machines, but we wouldn't doubt if it happened before the year was out. The ATS-V and CTS-V didn't look wholly different than the pedestrian versions of those cars, and this prototype indicates Caddy may follow a similar pattern this time around. All will be explained from GM soon, but for now, we wait.

Cadillac's Blackwing V8 was the best engine at the worst time

It should be clear that GM knows how to innovate and engineer excellent products when it wants to. Cadillac's 4.2-liter twin-turbo Blackwing V8 is recent proof of that. Yet, as related in an extensive Road & Track piece, the Blackwing became victim to some of The General's bugbears, like the reticence to — for whatever reasons — unleash its excellence everywhere, fund that excellence, and be consistent with that excellence over the long term beyond the Corvette and full-sized pickups and SUVs. The R/T story relates tales told by "several people deeply involved with the Blackwing project" about how an engine 18 years in the making was deprived of its reasons for being in less than three. Starting around 2000, GM spent a dozen years building Cadillac up to the point where the American luxury brand could rationally flip to the chapter called, "Taking the Fight to the Germans, but for Real this Time." The first steps in the plan meant an exclusive platform and an exclusive engine. The platform was called Omega. You know the engine's name. They were going to be the aluminum-blocked fist and velvet glove enabling Cadillac to break on through to the other side of luxury — proper luxury to global standards, that is — with a range of beautiful and dynamic crossovers and sedans. An engineer involved in the project estimates GM poured $16 million into the Blackwing's clean-sheet development. Many more seven-figure sums went into creating the first sedan on the Omega platform, the CT6. The automaker dropped millions again poaching ex-Audi and Infiniti chief Johan de Nysschen, and moving Cadillac's headquarters to New York City in 2014. Further pallets of cash funded the development and debut of the Escala concept at Pebble Beach in 2016. In 2018, GM revealed its dramatically named DOHC twin-turbo V8. Considering what came before, the Blackwing clearly wasn't designed for cars. It was designed for world domination. However, against the backdrop of plummeting sedan sales, the CT6 didn't sell like GM had hoped. The automaker hesitated to marshal another fleet of Brinks trucks to fund entries into a cratering bodystyle. Removing sedans from the world domination equation created more difficult math for the crossovers and the Escala.
