Now, here's an interesting blurb about what really went on with the "jeeps rolling problem"...

"Rolling Jeeps

SUVs have had their share of public relations problems. Nowadays they’re chided for their gas mileage. But a public scare about SUVs rolling over started back in 1980.

“I’m only going 8 to 10 miles an hour,” Morley Safer said from behind the wheel of a Jeep in a Dec. 21, 1980, CBS “60 Minutes” broadcast. “But this is what can happen when

the Jeep makes a J-turn at 22 miles an hour,” he added, as a video showed the vehicle flipping and rolling on top of dummy passengers.

In 1980 the Insurance Institute for Highway Safety, a group funded by auto insurers, released statistics on the Jeep CJ-5 suggesting it was prone to roll over under “normal” driving circumstances.

The Wall Street Journal and Washington Post ran the story, but the visual aids in Safer’s “60 Minutes” report were perhaps the most stunning – showing Jeeps turning over and tossing dummy passengers to the pavement, in what was implied to be normal driving circumstances.

The IIHS report, obtained from the group’s archives by the Business & Media Institute, shows that the group’s researchers ran a total of 435 tests to obtain eight rollovers. One of the Jeeps was tested at least 87 times before it rolled over. It was then reconfigured and tested another 72 times before it rolled over again.

More than a year later, American Motors Corp. was still suffering from image problems due to the reports. The Wall Street Journal reported in February 1982 that Jeep sales were “already 50 percent below” 1979 numbers when the report aired, and they “sank to about 65 percent below that rate” in 1981.

The Journal also reported AMC’s side of the story, noting the manufacturer was questioning the validity of the IIHS study as well as other studies suggesting Jeeps were more likely than other SUVs to roll over. “The automaker contends that the driving patterns were unrealistic because the steering was extreme, speed was prolonged, and brakes weren’t applied,” it reported.

The National Highway Transportation Safety Administration agreed. In a 1981 internal memo, the NHTSA critiqued Dynamic Science Incorporated, which conducted the IIHS tests, for using “abnormal test conditions and unrealistic maneuvers ... generated by an automatic control device which ... was programmed to provide input not entirely representative of driver input,” according to the book “The Liability Maze” by Peter Huber, a lawyer who is currently a senior fellow at the Manhattan Institute.

Unfortunately for auto manufacturers, stories like these can create stereotypes that live on even after the stories are debunked. The “60 Minutes” report and the IIHS report are highlighted, though discredited, are still being used to tarnish Jeep’s reputation.

A 2002 PBS “Frontline” special on the dangers of SUVs cited the reports. After outlining the rollover risk without bothering to mention the tests were discredited, the narrator noted, “Despite the rollover risk, Americans flocked to the Jeep.” Maybe it was because Americans realized Jeeps weren’t as dangerous as the media made them out to be.

A 2004 book, “High and Mighty: SUVs – The World’s Most Dangerous Vehicles and How They Got That Way,” cited the CBS report, also without mentioning that the study had been criticized by vehicle safety experts.

A 2005 University of California-Berkeley Traffic Safety Center newsletter cited the IIHS study and the CBS report in an article about SUV safety. That article didn’t mention the debunking of the IIHS’s findings."

Now you know the facts!

I am reminded of the Ford Exploder and Firestone Flip-A-Stone.
The Exploder/Firestone debacle was due to Ford specifying too low of air pressures. Firestone unfortunately was the tire supplier at the time and was wrongly made out to be the scapegoat.

Not wrongly. There will never be a firestone tire on any vehicle I ride in and certainly not own. From way back when the "721" was exploding about every third rotation. they have been explosive since the 70s. The Exploder debacle was just one of many.. if I ever want to destroy a car; maybe. ?

I had a early set of radials that started poping steel threads out of the sides near the tread. Also had a set of A/T that had tread seperation on 3 out of 4. I have not purchased Firestones since the seventies. Never had those issues with any other brand and I've done well over a million miles of driving.

That reminds me of the dangerous square body GM trucks with the fuel tanks mounted outboard of the frame rails, one of the amazing safety idiots did a demo that involved a vehicle t-boning the truck which resulted in the trucks fuel tank exploding, scary stuff for sure.
Except..... when reviewing the video frame by frame, the trucks fuel tank exploded just BEFORE impact.

Zach...a good lesson here for journalists who need to not only be objective about their own findings, but the findings they cite of reporters/investigators who came before them reporting similar things.

My sister owned a 1980 CJ-7 that flipped while she was driving it on the highway. Fortunately the roll bar pretty much saved everyones life inside.

Every vehicle is capable of flipping if not driven properly or certain conditions are met. Grade, surface, stationary obstructions, speed, turning angle, etc, all can affect a roll or not roll.

Glad no one died. I gotta ask though, the CJ-7 just randomly flipped? Or is there more to the story (e.g., someone hit her or she tried an evasive maneuver to avoid an accident)?
