Engine block heater issues force GM to recall 324,226 diesel heavy duty trucks

General Motors has issued a recall on 324,226 diesel heavy duty trucks that could be susceptible to short circuits, and consequently, potential fire. The recall affects several models of heavy duty Chevrolet Silverados and GMC Sierras with optional engine block heaters. GM is recalling seven different truck models spread across three years. The recall affects the 2017-2019 Chevrolet Silverado 2500HD, 2017-2019 Silverado 3500HD, 2019 Silverado 4500HD, 2019 Silverado 5500HD, and 2019 Silverado 6500HD, plus the 2017-2019 GMC Sierra 2500HD and 2017-2019 Sierra 3500HD. Specifically, it includes these models with the 6.6-liter Duramax diesel engines and the optional engine block heater. The recall technically deals not with the engine block heater itself, but the way it is connected. According to NHTSA campaign No. 19V328000, the engine block heater cord or the terminals that link the cord to the heater could short circuit. A short circuit could potentially damage engine components and result in a fire. According to The Detroit News, 19 fires have been reported but nobody has been injured. GM has yet to figure out a fix, and thus has not yet released a notification schedule for affected customers. If you believe your vehicle is part of the recall, contact GM customer service at 1-586-596-1733 and use reference number N182206310.

Opel CEO talks new EV, will likely be fresh face for Chevy, too

The rumored demise of the Opel Ampera has been confirmed, but there's good news, too. Opel CEO Karl-Thomas Neumann has been busy Tweeting information about the brand's next plug-in vehicle, admitting that the Ampera is on the way out but that plug-in vehicles are here to stay. His Tweets, in full, read: After the eventual run-out of the current generation Ampera, we'll introduce a successor product in the electric vehicle segment. Our next electric vehicle will be part of our massive product offensive – with 27 new vehicles in the 2014-2018 time frame. We see eMobility as important part of the mobility of tomorrow and we will continue to drive down costs & deliver affordability. As we learned earlier this week, the Ampera will not be refreshed when the current Chevy Volt is updated, most likely because of slow sales. Opel sold just 332 Amperas in the first five months of 2014. For now, General Motors is still building Amperas in Michigan for export to Europe. So, what might this new EV mean for the General Motors plug-in fleet? Official spokespeople are being quiet, but we think it's safe to say the new EV Neumann is talking about is not simply a rebadged Chevy Spark EV. This is the first official word about an entirely new EV, and we expect it will come to both the Chevrolet and Opel brands.

First 2015 Chevy Corvette Z06 engine blows up at just 891 miles

You've waited and watched and waited some more for the arrival of your 650-horsepower, $78,000 Chevrolet Corvette Z06. Finally, that joyous day arrives and you eagerly, but gingerly, begin to break-in the 6.2-liter supercharged V8 monster under your hood. Then 900-odd miles after delivery, your excitement grinds, quite literally, to a halt. That's what the owner of one 2015 Z06 claimed happened to him when a simple break-in drive resulted in a lunched engine. The owner, known as Lawdogg149 on Corvette Forum, says he was out breaking-in his car ahead of a January track event when it happened. "While making a pull from 35 miles per hour, I accelerated and shifted short of redline, and boom - the car began knocking. I pulled over and popped the hood. I could hear a loud knock coming from the No. 6 cylinder area along with a serious, grinding, metal-on-metal sound coming from the supercharger area," Lawdogg wrote. A subsequent trip to the dealer confirmed his concerns, with the service facility telling Lawdogg that the No. 6 valvetrain had failed. The dealer couldn't research the issue further, though, as General Motors requested the engine be returned for a more thorough evaluation. The good news for the Z06's unlucky owner, at least, is that GM will be covering the engine replacement under warranty, an expense that Corvette Forum estimates is a nearly $24,000 procedure. At this point, the two leading theories behind the engine's detonation involve a manufacturing defect – which could be why GM is so keen to tear the blown powerplant down – or a mistake on the part of Lawdogg. As Motor Authority points out, such an error could be something as simple as the Z06's owner accidentally shifting to first rather than third during his 35-mph pull. If, however, there's a deeper manufacturing problem with the Z06's engine, this might not be the only case we end up hearing about.
