2021 Cadillac Escalade, GMC Yukon, Chevy Suburban/Tahoe recalled for stall risk

General Motors is recalling just shy of 15,000 2021 Cadillac Escalade & Escalade ESVs, Chevrolet Suburbans and Tahoes, GMC Yukons and Yukon XLs that were shipped with fuel pumps that were built with a batch of what may be faulty electronic control modules. A pump with a bad module can result in intermittent function, resulting in drivability issues and potential stalls. No serious incidents or injuries have been associated with the issue.  GM says it discovered the issue after analyzing early recall data for the 2021 model SUVs and discovering an unusually high failure rate for fuel pumps manufactured by a single supplier – Vitesco. The company was able to identify the batch and initiate a recall campaign targeting just those vehicles.  "After reviewing the field data, GM determined there were 617 potentially relevant complaints, which were received between April 15, 2020 and August 24, 2021," the company's recall report said. "229 of these complaints reported a stall while standing or moving. No accidents or injuries associated with this condition were found." Any SUVs built with pumps from that batch but not yet sold are being held at dealers for replacement parts. It may take some time for GM to source replacements due to the ongoing electronic parts shortages.  "We are working with the supplier to obtain the required parts as quickly as possible," GM said in its notice to dealers. "When sufficient quantity of parts are available, the recall bulletin will be released and dealers can begin repairing vehicles."

GMC explains why the Hummer EV SUV has only 830 horsepower

GMC's 2022 Hummer EV pickup made its debut in late 2020 with a headline-grabbing 1,000-horsepower rating. Its SUV sibling broke cover yesterday with 170 fewer horses, so GMC executives had some explaining to do. Al Oppenheiser, the EV's chief engineer, pointed out that the SUV's wheelbase is about nine inches shorter than the truck's, which is called an "SUT" in GMC-speak. It's also about 20 inches shorter overall. Size matters in the electric car world; GMC can't stuff the SUT's big battery pack in the more compact SUV, and this directly influences power. He added that it would have been possible to build a 1,000-horsepower SUV by making changes to the battery pack's layout. His team would have needed to reduce cargo capacity and get rid of the flat loading floor, which were compromises that engineers were not prepared to make. Ultimately, 830 horses should be plenty for most drivers. "Frankly, we are not sorry that it's only 830 horsepower. There aren't many internal combustion engines that can say that. Will we be able to grow horsepower in the future? We are going to push that capability, and as the technology gets to the point where our batteries are smaller and more efficient, we will improve performance with any chance we get," Oppenheiser said. It helps that the Ultium battery technology GMC uses is extremely modular. Less powerful versions of the Hummer SUV are in the cards, too. At launch in early 2023, the model will exclusively be offered with the aforementioned 830-horsepower drivetrain, which offers around 300 miles of driving range. Pricing will start at $105,595 before options are factored in. Several months later, GMC will release an EV2X variant with up to 625 horsepower, about the same amount of driving range, and an $89,995 price tag before incentives.

GMC Terrain's first generation could get recalled for headlights

According to Car Sales Base, GMC sold 745,454 Terrain crossovers from the end of 2009 to the end of 2017, all but a few of them representing the first-generation model years of 2010 to 2017. According to the National Highway Traffic Safety Administration, the carmaker will need to recall almost all, due to a problem with excessively bright headlight reflections. NHTSA takes issue with the fact that federal motor vehicle regulations stipulate how bright headlight reflections are allowed to be within a certain arc of the headlight beam axis. In a certain area of the arc, the Terrain throws two small spots of light that are about 450 to 470 candela strong where the legal maximum at that point is 125 candela — one candela being equivalent to the light from one candle. The NHTSA wants the headlights replaced for being close to four times over this reflective limit, alleging this can cause "glare to other motorists driving in proximity." GM discovered the noncompliance in 2019, then filed a notice of noncompliance that requested an exemption from having to recall the crossover. GM's counterpoint to NHTSA was that the two areas of illegality were 80 degrees outboard of the headlight and 45 degrees up. You'd have to be Slenderman or a giraffe standing on the side of the road — our words, not GM's — to be blinded by the light. The automaker hadn't heard of any incidents nor complaints over the issue. The only customer feedback GM received was a Terrain driver saying the "left headlamp seems to have a portion of the light that shines up in the trees at near a 45-degree angle." Note, that's the left headlight, so the tree in question would likely be on the other side of the road. GM said oncoming traffic wasn't impaired by the excessive brightness. Due to these these mitigating factors, GM asked for an exemption from recalling the Terrains.    This week, NHTSA denied GM's petition.
