GM recalling 250,000 SUVs over door electronics

After a door-fire investigation that dates back to February, the National Highway Traffic Safety Administration has officially announced a recall today that affects around 250,000 General Motors SUVs for a faulty driver's door module. The recall applies to the Buick Rainier, Chevrolet Trailblazer, GMC Envoy, Isuzu Ascender and Saab 9-7X from the 2006 and 2007 model years, as well as the 2006 Chevrolet Trailblazer EXT and GMC Envoy XL for vehicles sold and/or registered in the Snow Belt.
Road salt use in these midwestern and northern states can lead to corrosion of the driver's door module on these GMT360 and GMT370 vehicles, which allows water to come in contact with the circuit board. If shorted out, the vehicle's power door locks and power windows will not work, and could possibly lead to overheating and, in some circumstances, a fire. No official word on how many total vehicles caught on fire, but back in June, 28 fires had been reported to the government agency. A fix for the problem is still being worked out, but all affected vehicle owners will be notified by GM.

Smaller Cars Endure Big Problems On Crash Test

In a crash test of 11 of the smallest cars on the market, only one vehicle received an acceptable rating. The rest received marginal or poor ratings in the study, providing evidence that supports a widely held notion that smaller cars are among the least safe on the road. No other vehicle group has performed as poorly on a new crash test than these mini cars, says the Insurance Institute for Highway Safety, the nonprofit group that conducted the testing. The latest results of which were released Wednesday. The Chevrolet Spark was the only car earning an overall "acceptable" rating on the small-front overlap test, and even that vehicle had its shortcomings, IIHS said. "Small lightweight vehicles have an inherent safety disadvantage," said Joe Nolan, the senior vice president for vehicle research at IIHS. "That's why it's even more important to choose one with the best occupant protection. Unfortunately, as a group, minicars aren't performing as well as other vehicle categories." The Mazda2, Kia Rio, Toyota Yaris and certain Ford Fiesta models all received "marginal" overall grades on the test, while the Mitsubishi Mirage, Nissan Versa, Toyota Prius C, Hyundai Accent, Fiat 500 and Honda Fit all earned "poor" ratings. Results from these sub-compact cars fare much worse than vehicles sized just a little bit bigger, IIHS said. Among 17 cars evaluated in the small category, five earned "good" ratings and five more earned "acceptable." Only introduced a year ago, the small-front overlap test has quickly become a key indicator of differences in automotive safety. IIHS introduced it as a way to replicate what happens when the front corner of a vehicle collides with a tree or utility pole at 40 miles per hour. In the real world, these sorts of accidents are more dangerous than others, in part because they bypass the front-end crush zones on most cars.

Without a grade of acceptable or better, they cannot qualify for the IIHS' overall Top Safety Pick+ honor, given annually to the safest models on the market.

GM applies for LT5, LTX trademarks... are new small block variants coming?

Recently discovered General Motors trademark applications for LT4, LT5, LT88 and LTX have observers wondering what kind of high-performance offerings could be on their way. A new LT4 would mark a return of the engine designation first used on the Corvette Grand Sport, SLP Pontiac Firehawk and SLP Chevrolet Camaro SS from 1996 and 1997. Supposition at Corvette Forum - which provided advance intel on the C7 like these leaked images - believes a new LT4 could go into the high-performance trim of the next-gen, 2015 Camaro that would be more powerful than the 580-horsepower Camaro ZL1.
Seeing an LT5 again would also be déjà vu - in its former life it was a 5.7-liter V8 for the C4 Corvette ZR-1 from 1990-1994 designed by Lotus, producing from 370 hp to 405 hp. A mix of rumor and hope is that the new LT5 will be a supercharged evolution of the 6.2-liter LT1 (pictured) placed in the new C7 Corvette, and that it will go into the C7 version of the ZR1 pumping out something like 700 hp.
The LTX trademark is, as with that last letter, a complete mystery. If the "X" isn't a generic way to denote the whole LT family, it's wondered if it LTX could refer to a crate motor offering like the LSX.
