Cadillac XT4 Common Problems

ELECTRICAL SYSTEM

Owners report multiple electrical system issues with the 2024 Cadillac XT4, including unexpected activation of the Automatic Emergency Braking system and sudden vehicle shutdowns while driving. Complaints frequently mention that the vehicle's infotainment and dashboard screens go black, and drivers experience a loss of braking and steering control. These issues often occur at various speeds, including highway driving, and in some cases, the vehicle stalls or decelerates rapidly. Several complaints note that these problems have persisted despite attempts at dealership repairs, with some vehicles affected as early as 3,000 miles. Safety implications are significant, with owners describing near-miss accidents and situations where the vehicle's behavior could lead to collisions or loss of control.

POWER TRAIN

Owners of the 2019 Cadillac XT4 frequently report issues related to the powertrain, with common symptoms including check engine lights, loss of engine power, and transmission problems. Complaints often mention engine overheating, reduced engine power, and transmission failures, with some owners experiencing these issues shortly after warranty expiration or around 31,000 miles. Multiple reports describe vehicles not starting, requiring towing, or experiencing severe jerking during acceleration, potentially indicating throttle or transmission defects. Safety implications include concerns about stalling in traffic and the potential for rear-end collisions due to jerky acceleration. These patterns suggest that prospective buyers should be aware of potential powertrain issues, especially with vehicles approaching or exceeding 30,000 miles.

ELECTRICAL SYSTEM

Owners report several issues with the 2025 Cadillac XT4's electrical system, particularly related to the OnStar service and telematics module. Complaints frequently mention that the OnStar system fails to operate correctly, leading to battery drainage and rendering the car inoperable. Additionally, multiple owners describe problems with emergency calling features and built-in navigation, with systems unable to provide accurate location data or function reliably, posing potential safety risks. Symptoms include spontaneous vehicle starting and dashboard warnings like “Service Emergency Calling.” These issues are noted at various mileage points, such as around 17,000 miles, and parts necessary for repairs are often unavailable or backordered, leaving some vehicles unrepaired.

FUEL/PROPULSION SYSTEM

Owners report that the 2024 Cadillac XT4 experiences issues with the fuel pump driver control module, leading to vehicle stalling. Complaints frequently mention the vehicle shutting off suddenly, both while driving and when stationary, with no prior warning signs. Affected vehicles often cannot be shifted into neutral, complicating towing and creating potential traffic hazards. These incidents typically occur without any dashboard alerts, and multiple owners describe needing to have the vehicle towed to a dealership for module replacement. The stalling problem poses a safety risk, particularly if it occurs in traffic, as it may obstruct traffic flow and increase the risk of accidents.

SERVICE BRAKES

Owners of the 2024 Cadillac XT4 frequently report issues with the vehicle's automatic braking systems. Complaints often describe unexpected engagement of the Automatic Emergency Braking (AEB) system, leading to sudden stops without obstructions, sometimes referred to as "phantom braking." One incident involved a crash when the AEB engaged at an intersection, resulting in a rear-end collision. Additionally, there are reports of high-pitched squealing noises under light braking at low speeds, particularly during initial stops of the day. These issues have been noted from the time of vehicle purchase, with some owners indicating that dealers have acknowledged the problems but have not provided permanent solutions. Safety implications are significant, especially with the potential for rear-end collisions due to unexpected braking.

Severity signals: 1 crash, 0 fire, 0 injury reports

POWER TRAIN

Owners of the 2023 Cadillac XT4 frequently report issues with the vehicle's 9-speed automatic transmission not engaging 9th gear automatically, requiring manual intervention to shift properly. Complaints also describe a lack of smooth shifting in the lower gears (1-3) during deceleration, with a jerking sensation as if a clutch is popping. These transmission issues are reported to occur consistently from the time of purchase, with one vehicle having fewer than 5,000 miles. One owner also reports a separate incident where the vehicle unexpectedly powers off while driving, citing a potential battery or alternator issue. No crashes or fires are reported in these complaints, but the sudden loss of power while driving may pose a safety risk.

FUEL/PROPULSION SYSTEM

Owners report recurring issues with the fuel pump control module in the 2021 Cadillac XT4, leading to vehicle stalling and failure to start. Complaints frequently mention that the vehicle either stalls while driving or fails to start, with some owners noting a clicking noise or the illumination of the check engine light. Problems have been reported at various mileages, with specific instances at approximately 13,765 miles and 29,342 miles, and another case at 15,063 miles and 34,611 miles. In terms of safety, multiple owners describe the vehicle stalling on the road, which could pose a risk in traffic situations. Buyers considering a used 2021 XT4 should be aware of these potential issues, particularly in vehicles not covered by the existing recall.

ENGINE

Owners report several engine-related issues with the 2019 Cadillac XT4, primarily involving oil leaks and timing chain tensioner problems. Complaints frequently mention oil leaks from the camshaft oil seal and camshaft carrier, often identified during routine service without prior symptoms, at mileages ranging from 22,000 to 51,534. Another issue involves the timing chain tensioner failing around 17,000 miles, with symptoms including noise at cold start until oil pressure builds. Multiple owners describe costly repairs, with some noting the need for repeated attempts to resolve oil leak issues. There are no reports of crashes, fires, or loss of control related to these engine problems. This information may be useful for prospective buyers considering the potential for early engine repairs.
