According to Consumer Reports, Chrysler has addressed a handling issue with the 2011 Jeep Grand Cherokee that the publication discovered during independent testing. During a double-lane-change emergency maneuver, CR testers noted a considerable amount of skidding and hopping at the very limit of traction. Chrysler engineers then went to the magazine’s test track to review the findings before returning to Auburn Hills to come up with a solution. In December, the automaker released a software update for the vehicle’s stability control, and all Grand Cherokee models manufactured since then have come from the factory with the fix.

Consumer Reports was recently able to put the updated 2011 Grand Cherokee through its paces at the track once again and found that the issue had been corrected. The big SUV managed to maintain an average speed of 50 mph through the course and behaved itself at and beyond the limits of the vehicle’s traction. The fix has helped to improve the vehicle’s Consumer Reports rating for the Grand Cherokee from a 66 to a 71.

Cadillac recalling 50,000 CTS models worldwide over potential handling fault

General Motors and the National Highway Transportation Safety Administration have announced a recall of certain 2009 and 2010 model-year Cadillac CTS models. The notice covers around 50,000 units worldwide, 11,147 of which were sold in the States.

According to NHTSA, jam nuts on the vehicles’ suspension could come loose over time, eventually allowing the toe link to completely separate from the vehicle. If this happens, the rear wheel could turn in or out, making the vehicle difficult to steer. GM says that owners may hear a metallic clanking noise in the rear of the vehicle as a warning before this happens.

So far, no accidents or injuries have been reported as a result of the defect, though NHTSA warns that if left untreated, owners could experience a loss of control.

GM says that it will install new jam nuts free of charge and replace the rear suspension toe link as necessary. A recall schedule hasn’t been established yet, but owners should hear something soon. Hit the jump for the full recall notice.

CamberTire could increase MPGs, improve handling

Filed under: Aftermarket, Safety, Technology

If you have even a passing interest in sportscars, you may have noticed something suspicious about your favorite speed machine’s tires. Typically, manufactures build a certain amount of negative camber (tipping the top of a wheel inward) into the suspensions of their sportscars. This allows the tires’ contact patches to grow larger under hard cornering, thereby giving the vehicle more grip at the same time. Grip is good, but negative camber has plenty of, well, negative side effects as well. For starters, the vehicle’s ride is compromised and the tires are more likely to exhibit uneven wear.

An inventor by the name of John Scott may have come up with a solution that allows most of the benefits of negative camber while maintaining treadwear and safety. Scott designed a tire with a slightly larger circumference on the outer sidewall than the inner sidewall. This allows the suspension to be adjusted with plenty of negative camber while maintaining the contact patch of the tire.

Chances are that the new rubber will be a hit in the aftermarket world where getting a vehicle as low as possible often means building in plenty of camber, but Scott claims that the new tires can benefit nearly every car on the road today by offering up better handling, shorter braking and better grip compared to OE tires.
