Some 2012-13 Chevy Volts may not have enough battery coolant

The 2012 and 2013 model year Chevrolet Volt extended-range plug-in vehicle may have a battery glitch caused by low coolant levels. No recall has been issued and General Motors is taking care of the issue at no cost to drivers. Some of the affected Volts may have lower-than-advisable coolant levels because of some pesky air pockets in the car's cooling circuit. When the coolant levels get too low, the charging system for the battery powering the car's onboard generator (i.e. the Rechargeable Energy Storage System, or the RESS) may be shut down, turning one's Volt into a run-of-the-mill gas-powered car, and a pricey one at that. The Car Connection says GM is advising owners of the '12 and '13 Volts to contact their local Chevy dealer for a free fix. GM representatives didn't immediately respond to a request for comment from AutoblogGreen for more details. We believe this is a separate issue than the one that brought 8,000 Volts back to the dealers for a battery coolant fix, what GM called a "voluntary customer satisfaction effort," a few years ago. General Motors sold 23,094 Chevy Volts last year after selling 23,461 Volts in 2012, so that fix-it list may get fairly lengthy. Check out a GM-Volt.com user thread related to this issue here. *UPDATE: Chevrolet spokesman Randy Fox confirmed in an e-mail to AutoblogGreen that the company issued a service bulletin to dealers that they may need to top off coolant levels on certain Volts because of the issue, and that the vehicle will "return to normal charging operation" once that's done.

Jay Leno gets pulled over while roaring in a Corvette Z06 convertible

No one is above the law, even if that person is a certain silver-haired auto enthusiast with a popular weekly video series about the cars in his garage. This week, Jay Leno experiences the 2015 Chevrolet Corvette Stingray Z06, but he also gets to have a meeting with some of California's Finest immediately after a high-speed blast. As opposed to the full-bore Z06 coupe with the seven-speed manual, Leno gets behind the wheel of the slightly heavier convertible version with the eight-speed auto. Being a droptop doesn't bother him too much, but Leno makes it obvious he wishes that he could be shifting for himself. Even if the auto is technically quicker, Leno says that swapping gears gives him something to do while driving. Of course, one of the major advantages of the convertible is the ability to listen to the Z06's thumping V8 unimpeded. With 650 horsepower and 650 pound-feet of torque from 6.2-liters of supercharged muscle, it already puts down impressive numbers, but the sound might just be the best part of all. Around town, the 'Vette is quiet enough to easily blend in with the rest of traffic. However, tip the throttle down and the valves in the exhaust open up to turn the engine into roaring monster. Be careful where you make this thing howl, though, because it's pretty easy for the police to take notice. The host finds that out the hard way in this week's episode of Jay Leno's Garage.

10 of 18 midsize SUVs earn 'good' IIHS side impact safety rating

It's not terribly surprising that midsize SUVs earned better safety ratings than small SUVs in the latest side-impact tests performed by the Insurance Institute for Highway Safety (IIHS). Just how much better they scored, on the other hand, certainly raises an eyebrow. Ten out of 18 midsize SUVs earned the highest rating of 'good' in the stringent new test, altered for vehicles starting with the 2020 model year with a heavier barrier (4,200 pounds) that moves at a higher speed (37 miles per hour) and is fitted with a hard honeycomb frontal structure. By way of contrast, just one out of of 20 small SUVs earned a 'good' score.  SUVs that receiving 'good' scores were the Ford Explorer, Infiniti QX60, Lincoln Aviator, Mazda CX-9, Nissan Pathfinder, Subaru Ascent, Toyota Highlander, Volkswagen Atlas, Volkswagen Atlas Cross Sport and Volkswagen ID.4. For EV fans, it's worth noting the ID.4 was the only electric vehicle included in the test. The Buick Enclave and Chevrolet Traverse scraped away with 'acceptable' ratings while the Honda Passport, Honda Pilot, Hyundai Palisade, Jeep Wrangler 4-door, Kia Telluride and Nissan Murano were deemed merely 'marginal' in the tough new test. Only two models — the Mazda CX-9 and Volkswagen ID.4 — earned a "Good" rating in every test category.  Interestingly, the Jeep Wrangler would have scored a 'good' rating if it were equipped with side airbags for the rear seating positions. It would likely be an engineering challenge to equip its removable top and/or doors with airbags, but the lack of that safety feature allowed the head of the rear passenger dummy to hit the vertical support of the top. Otherwise, the Wrangler scored good ratings across the board. The new Ford Bronco, which makes more allowances for side-impact safety, has not yet been tested.  The popular Hyundai Palisade and Kia Telluride SUVs stand out in the test with 'poor' ratings for driver pelvis injuries. The Nissan Murano, a vehicle last redesigned for the 2015 model year, was the only vehicle tested that received a 'poor' rating for its structure and safety cage. Videos of the tests of 12 of these 18 SUVs can be found on the IIHS' YouTube page.
