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.

Fernando Alonso just misses qualifying for Indy 500 on first day

Former Formula One world champion Fernando Alonso will need a clutch run on Sunday to qualify for the Indianapolis 500 on May 26 after he failed to seal a guaranteed spot on Saturday. The Spaniard tried fives times to put his McLaren Racing Chevrolet in the top 30, but wound up one spot short. He can make the 33-car field only through a six-car shootout on Sunday that will determine the race's final three drivers. "We have another chance to be in the race," Alonso, who is seeking to make his second Indy 500 field, told IndyCar TV. The Spaniard twice got inside the top 30 but both times was bumped outside the mark, with JR Hildebrand and Graham Rahal the final two drivers to seal qualifying spots. Britain's Pippa Mann will be the only woman in the race, qualifying 30th in 227.244 mph. Race positions 10-30 were determined during the day-long qualifying with Saturday's nine fastest drivers set to return on Sunday to decide pole. Spencer Pigot, driving the Ed Carpenter Racing Chevrolet, led qualifying with a four-lap average of 230.083 mph. He was followed by 2018 winner Will Power of Australia (230.081) and Simon Pagenaud of France (229.854). The troubles for Alonso, whose top four-lap average was 227.224 mph, were exacerbated by a punctured tire in his first qualifying run. "That didn't help," Alonso told reporters. "But, obviously, our performance has been quite bad all week. Quite poor." The Spaniard crashed his Chevrolet in practice on Wednesday and missed nearly two full days of practice while a backup car was prepared. He returned on Friday. Alonso said he was worried the McLaren team was "not ready for the challenge." "We've been slow. You see Juncos Racing crashing yesterday and being ready at 6 o'clock. That's impressive," he said. "For us, we've been a little bit slow on everything." Alonso is bidding to join Graham Hill as the only drivers to achieve the 'Triple Crown of Motorsport' with an Indy 500 victory. He previously won the Monaco Grand Prix and Le Mans 24 Hours race. He also won two Formula One drivers' titles.

GM recalls nearly 340,000 large SUVs to fix daytime running lights

General Motors has initiated a recall campaign for more than 338,000 of its large SUVs to address a potential defect in the onboard computer software that controls the daytime running lights. In some cases, the DRLs may remain on even when the headlights are enabled, which creates additional glare for oncoming drivers at night and fails to comply with federal regulations for headlight performance.  "GM determined that the body control module (BCM) software in these vehicles, under a combination of certain pre-conditions, may fail to deactivate the DRLs when the headlamps are on," GM's recall report said. "A regulatory assessment was conducted to evaluate whether the condition presented a potential noncompliance with the DRL activation requirements in S7.10.5, Table I-a. of FMVSS 108. On October 27, 2022, GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a recall for potential noncompliance with this standard." GM says the recall covers the 2021 model year GMC Yukon and Yukon XL, 2021 Chevrolet Tahoe and Suburban, and 2021 Cadillac Escalade and Escalade ESV. The company says all models produced within that operating window include the improperly programmed body control module, meaning all vehicles within the recall population may exhibit the problem. The issue was discovered by a GM engineer during validation testing in August, prompting a deeper investigation and eventually leading to the recall itself.   The module's software can be updated by GM dealers, so it should be a quick fix for customers. Notifications will be mailed to owners in December.  Related video: Recalls Cadillac Chevrolet GMC Ownership Safety SUV Luxury
