The Cadillac CTS, an executive car produced by General Motors (GM) from 2003 to 2019, spanned three generations. Priced similarly to compact luxury cars, it aligned more with mid-size competitors in size. Replacing the Catera and indirectly preceding the CT5, the CTS was designed by Wayne Cherry and Kip Wasenko for the first model and by Bob Boniface and Robin Krieg for the third. The original model, introduced in 2003, was a rear-wheel-drive GM brand built on the Sigma platform and equipped with a fully independent suspension. Originally powered by a 3.2-liter V6 engine producing 220 hp, it evolved over time, with a 3.6-liter DOHC V6 introduced in 2004, and a 2.8-liter variant replacing the 3.2-liter version in 2005. The second generation CTS, unveiled in 2006, took design cues from the 2003 Cadillac Sixteen concept car, offering expanded dimensions, a revamped exterior, advanced tech features, and superior brake components. The third generation, introduced in 2013, offered the same engines as the ATS, with a new twin-turbo direct-injection V6 engine delivering 420 hp reserved for the CTS-V. The 2014 CTS was named Car of the Year by Motor Trend, lauded for its handling, reliability, and construction, despite criticisms of its CUE multimedia system.

Cadillac CTS vehicle owners commonly report two significant issues. The first is early engine failure, indicated by issues like misfiring or difficult starting, accompanied by a whining noise. In these cases, a faulty fuel pump is often the culprit. The second common issue pertains to the braking system. Drivers have noted strange noises, pulsating and vibrating brake pedals, and slow brake response. Visible score marks on the brake rotors often accompany these symptoms, indicating the need for immediate replacement of either the brake disc or brake pad to ensure the safety of both driver and passengers. Apart from these, there are other minor yet significant problems to attend to. The headlight, for instance, can become dim over time, impairing the driver's vision. Similarly, the windshield wiper or wiper blade can wear out, affecting visibility during adverse weather. Additionally, a wheel cover that helps reduce the accumulation of dirt and moisture to maintain wheel function can also wear out over time. Therefore, these components need timely attention and replacement for the vehicle's safe operation.
