2011 Jeep Grand Cherokee - Click above for high-res image gallery

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.

      Good job.

      As much as I find CR a waste of time, I don't think they're biased in a pro-domestic, anti-import way. I just find them tedious. Everything they write has the interest and flair of a refrigerator disclaimer tag.

      but now that the handling is "fixed" how about a 2 door Grand Cherokee, lol:

        well, given they rate refrigerators and vacuum cleaners too, I don't think you're too far off :D

        at any rate, CR carries a huge amount of weight with the non-enthusiast car buyer, so the automakers are pretty much compelled to do some butt-smooching.

      Interesting.... They allowed Chrysler to use the CR track to cofirm their findings, but forced Toyota to reconstruct their track from aerial photographs? What's up with that?

      Glad Chrysler was able to recalibrate and make everything happy again.

      It's a Jeep for God sake, not a Camry. CR go review a toaster and let Jeep be Jeep!!!

      You'd think they'd try a double-lane change maneuver on their own before giving it the OK

      "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."
      What about the ones manufactured and sold with the gimpy software? When they are reported to be recalled and fixed, then, and only then, can Chrysler pump its own image.

        Why don't you read the CR article.

        "Chrysler started incorporating the update as of December production. All dealers have been performing that repair free for customers since early January and the fix has been applied to all vehicles in stock. It involves a "reflash" of the vehicle software."

      Consumer reports blows!

      They been in favor of Toyota for years based totally on other peoples perception.

      Some how its not popular to worship Toyota anymore.

      Consumer Reports needs people to buy their rag.

      They can`t rate washing machines right let alone cars.

      I know, I bought their top rated washer. It was total junk!

        Consumer Reports said Toyota set the standard for reliable, comfortable cars for most of the 90s and 00s. In 2007, CR started voicing some concerns about the Tundra's 4WD system and the Camry's 6-speed automatic. They were, in fact, the first publication to report on these serious problems.

        So either you 1) didn't know that, or 2) just think Toyota never made good cars. Either way, you're dead wrong.

        "So either you 1) didn't know that, or 2) just think Toyota never made good cars. Either way, you're dead wrong."

        There`s a difference beween being good or #1 in reliability and being infallible.

        Of course Toyota makes good cars, so does everyone else.
        CR had Toyota on a pedestal.

        I use to subscribe to Consumer Reports. For a domestic car to get a favorable review it had cream Toyota. Guess what, being just as good wasn`t good enough.
        Since Toyota in fact makes good cars no one could blow them away, bias was in Toyota`s favor.
        I wish I could explain it better. The casual reader of Consumer Reports wouldn`t catch the BS. I read alot of CR to the point I lost respect for their findings.
        My loss of respect was partly confirmed by the recomended washer I bought.
        It`s not that simple but thats part of my experience.

        FWIW - as CR uses its own subscribers as the source of information, at some point, a selection bias creeps in. CR readers favor a brand, therefore it rates higher. Then because it rates higher, CR readers buy more of that brand. Hence, self-fulfilling prophecy.

        However, my biggest beef with CR is that they don't publish their metrics in more detail - anywhere. All you get are those little dots - and it's often hard to tell the actual difference between a half-dot and a full dot. Any good statistician can tell you that having a "statistical difference" isn't always a "relevant difference" - but with CR's publications, you can't even tell that.

        And for those that don't understand what I mean, imagine this:

        Two makers have slightly different flaw rates in a CR survey - say Brand X has 2.1% and Brand Y 2.4%.

        But because CR ranks in quartiles, Brand X gets a red dot and Brand Y gets a black one. However, no mention is made as to whether or not Brand Y had a bad sample, and their actual defect rate is something else - what a statistician would list as a probability of error, or "confidence interval".

        Therefore, Brand Y gets derided as "bad", even though 1) we don't know if the number is accurate, and 2) the difference between Brand X and Brand Y only affects 3 out of 1000 products.

        Oh, and as CR doesn't tend to report major vs. minor issues separately, it's hard to know if Brand X's failures are major flaws vs. Brand Y's user annoyances.

        And that's my $0.02.

      Chrysler is probably playing Consumer Reports game and pacifying therm . Consumer Reports like to feel in control and if not, they will try to destroy you. They don't understand software so a software changes will suffice. Chrysler engineers are probably laughing, but the bottom line is, it worked.
        • 4 Years Ago
        Enlighten us, then, on how the stability control's PROGRAMMING has nothing to do with SOFTWARE, if you could be so kind.

        You CR haters really need to get some better material!
      • 4 Years Ago
      It's pretty cool how something like this can be so quickly and easily fixed by a software update on vehicles already on the road.
        • 4 Years Ago
        Kind of amazing how much is controlled by software in today's vehicles.

        That's why there are only a few suppliers in the ABS business. I used to work for one and they figured almost anyone could figure out how to build the hydraulic pump, but it would cost them $2 billion to develop the software to run the thing. Needless to say, they guarded their software closely.
