In response to the rankings, Fiat Chrysler said: "We continue to aggressively pursue both product and launch-quality improvements as they are top priorities for the Company and our internal measurements are showing progress."
Ford responded to Lincoln's rating by saying: "In 2012, Lincoln began its journey with four all-new products in four years. Each of those — The MKZ, MKC, MKX and soon, the Continental — continues to reflect our rejuvenation as a brand as witnessed by recent sales and quality awards. The MKS has received positive input from this change for Lincoln and clearly we have learned a great deal in this short time. We will continue to improve as we write the next chapter for Lincoln but feel encouraged about the progress thus far."
General Motors' Cadillac, whose Escalade was named the lowest-rated large luxury SUV, declined comment.
Simply because a model is rated poorly does not mean buyers have steered clear of them.
Take the Mercedes-Benz CLA250, for example. Consumer Reports said it's the worst compact luxury car on the market, with an interior that is "noisy and cramped." But last year, CLA sales in the U.S. increased 8 percent, outpacing the industry growth rate of 5.4 percent.
When asked for comment on the rankings, Mercedes Benz USA said: "Lists like this may make good headlines, [but] they by no means provide a universal perspective. The most accurate measure is when consumers vote with their wallets and CLA250 sales have increased year after year since introduction."
Consumer Reports pointed out that some of the models on its list are near the end of their current production run, so those that are still in dealerships could have sizable incentives that would make them more attractive.
But for drivers tempted by those deals, Consumer Reports said to be careful, as what looks good in a showroom may not feel good out on the road.
Here is Consumer Reports' full list of lowest-rated cars.
