GM recalls select Tahoes, Yukons, Escalades for rear driveshaft issue

GM is recalling a number of its full-size SUVs due to an issue with the rear driveshaft assembly that could ultimately result in driveshaft failure. The actual number of total vehicles involved in the recall is small at just 1,789, but it’s spread out across the entire 2021 model year full-size GM vehicle lineup. That means a small number of every model is being recalled, including the Chevrolet Tahoe, Suburban, GMC Yukon, Yukon XL and the Cadillac Escalade and Escalade ESV. GM traced the issue back to certain driveshaft assemblies with ball bearings that were not properly heat treated. If theyÂ’re not properly heat treated, GM says that the balls may deform over time, causing noise and vibration. Continue to drive in this condition, and GM says the affected joint in the driveshaft assembly could seize, causing loss of drive power. However, the problem wonÂ’t present itself all at once, as GM says there will be a gradual increase of noises and vibrations before total failure. For those few owners with affected vehicles, GM says that it will replace the left and right rear driveshaft assemblies with properly-built units. Per usual with recalls, this will be done at your local dealership at no cost to the owner. If you have one of the recalled SUVs, expect to be notified mid-March. Related video:

GM Ultium tech can scavenge heat from everywhere, even you

GM likes to give us tidbits about its Ultium platform from time to time, and today it’s telling us about the platformÂ’s ability to capture waste heat from the propulsion system. In addition to capturing from the propulsion system, it can also capture humidity from both inside and outside the vehicle and even from passengersÂ’ body heat. Yes, you, your family and/or your friends are a usable heat source as far as GM EVs are concerned. It then deploys the heat in an advantageous way. If at this point, youÂ’re screaming, "Heat pump!" youÂ’d be right. WeÂ’re talking about an elaborate heat pump system that GM is using for its Ultium-based vehicles. Every Ultium-based GM vehicle gets this system that is covered by 11 patents and four publications. The waste heat it collects is used in a number of ways, but its primary use is to heat the cabin quickly and efficiently. GM claims it can heat the cabin of its Ultium-based vehicles quicker than vehicles with traditional internal combustion engines. Plus, when put to use, GM claims that using the heat pump provides its EVs with up to 10% more range than theyÂ’d have without. Beyond heating the cabin, the heat pump is capable of putting waste heat to use by preheating the battery prior to charging so that you can charge quicker. The system can even cool the propulsion system in preparation for Watts to Freedom (WTF) launch control starts. GM says this was vital in helping the Hummer EV achieve its bonkers 0-60 mph time of about 3 seconds. “Having a ground-up EV architecture gives us the freedom to build in standard features like UltiumÂ’s energy recovery capabilities,” said Doug Parks, GM executive VP of global product development, purchasing and supply chain. “This helps us squeeze more efficiency, performance and overall customer benefit out of our EVs.” GM says itÂ’s been developing heat pump technology since the EV1 and its heat pump. This is the modern evolution of that technology, and GM says itÂ’s going to be implemented in every Ultium-based vehicle as a standard feature.

Autoblog Minute: Ford Ranger, UK Mustang, Hyundai Hybrid

Ford may bring the Ranger back to the US, the UK goes nuts over the Mustang, and the battle of hybrids heats up with spy shots of the Toyota Prius and a new Hyundai. Autoblog's senior editor Greg Migliore reports on the weekly recap edition of Autoblog Minute. Show full video transcript text [00:00:00] Ford may bring the Ranger back to the US, the UK goes nuts over Mustang, and the battle of hybrids heats up with spy shots of Prius and a new Hyundai. I'm Autoblog senior editor Greg Migliore and this is your Autoblog Minute weekly recap. 2011 was the last time we saw Ford's midsize pickup in the US but according to a report from the Detroit News we could see production of the Ranger at the [00:00:30] Dearborn automaker's Michigan Assembly Plant as early as 2018. Ranger could compete with the Chevy Colorado and perhaps revive the compact and midsize pickup market for Ford, but the future of Ranger in the US depends a lot on Ford's ongoing negotiations with the UAW. About 2,000 orders for the 2015 Mustang were placed in the UK, tying up production of the pony car until July 2016. According to details in a press release from Ford UK, [00:01:00] it looks like Brits are a lot like their American cousins, opting for the 5.0 liter V8, with Race Red as the popular color of choice. Photos of the 2016 Toyota Prius leaked generating a lot of buzz over the styling. This fourth generation Prius will have some new competition as spy shots of a new Hyundai also surfaced this week. The car is said to be a hybrid and a bonafide "Prius fighter." Those are the highlights from the week that was. Be sure to check out my full recap this Saturday, [00:01:30] including the latest in FCA rumors for 2016. For Autoblog, I'm Greg Migliore.
