While the Cadillac CTS may be one of the sportiest midsize luxury sedans out there, it has a very low-reliability rating from JD power, with only two out of five stars.

Overall, the Cadillac CTS has some of the poorest reliability ratings across the board, as well as one of the lowest within its class.

According to, older Cadillacs are prone to engine problems. The worst models for engine problems were 2007, 2006, and 2004.

The worst model year overall was in 2009, where there were over 33 reported issues, ranging from the engine, transmission, to even electrical problems.

If you are thinking of getting a Cadillac CTS, consider newer models beyond the 2014 range. 2015, 2016, 2017, 2018 models all received three complaints or fewer on, a strong improvement to the previous models.

If you’re looking for a similar car within the same class, you should look to the BMW 5 Series instead. Although the BMW may more expensive, it’s significantly more reliable and overall a better car.

The Tesla Model X is one of the top ten least reliable cars as reported by the consumer reports. While the electric-powered Model X costs close to six figures, it’s said to be more showy than practical.

When it comes to reliability, there have been many reports regarding the car’s body hardware, paint and trim, in-car electronics, and noises and leaks. There have been cases where owners sued the Tesla carmaker, citing many problems regarding the doors and software in the Model X, demanding the company issue a refund.

3. Jaguar F-Pace

Jaguar’s best-selling vehicle, the F-Pace lands itself on top of Consumer Reports’ least reliable cars.

The majority of complaints were related to the car’s infotainment software and noises and leaks, rather than any mechanical breakdowns. Overall, it’s not a major surprise that a Jaguar vehicle is on this list, as the brand has never been a leader when it comes to quality and reliability.

While it’s common to see problems with the infotainment system with other brands, there have also been hardware issues like reports of the engine overheating.

It looks like there have been many frustrated and upset customers on the fpace forums, drivers who not only need to bring their cars to mechanics regularly, but upon selling their vehicle, discovered that the Jaguar F-Pace also depreciates quickly. Yikes! Best to avoid the Jaguar F-Pace if you can.


Factory recalls are issued when a vehicle fails to meet safety or quality standards. If you’re shopping for a used car, see if any factory recalls have been issued before buying.
