What owners reported

Issue summaries by Cadillac XT6 model year

ELECTRICAL SYSTEM

Owners report multiple electrical issues with the 2020 Cadillac XT6, particularly with the body control module, backup cameras, and fuel gauge. Complaints frequently mention the body control module needing replacement, sometimes immediately after purchase. Backup cameras intermittently fail, displaying a warning symbol, and are linked to a service bulletin suggesting a cable replacement. Fuel gauges also malfunction intermittently, not showing fuel levels accurately, which requires dealership intervention but often without error codes. These issues occur across a range of mileages, from as low as 400 miles to over 30,000 miles. Safety implications include potential driving risks due to unreliable fuel readings and non-functional cameras, which could affect vehicle operation in critical situations.

POWER TRAIN

Owners report several power train issues with the 2024 Cadillac XT6, primarily involving transmission malfunctions. Complaints frequently mention transmission slipping, failure to engage reverse gear, and sudden jerking during shifts, particularly between 2nd and 4th gears. Some owners describe a complete loss of power or failure to accelerate, with one noting the vehicle erroneously switching from automatic to manual mode. Mileage at the time of failure varies, with one report at 114 miles. Safety implications are notable, as one owner experienced power loss while driving, though no crashes or injuries are reported. These issues may lead to significant repair needs, with some parts reportedly on backorder.

POWER TRAIN

Owners of the 2020 Cadillac XT6 frequently report transmission-related issues, with symptoms such as transmission jerking, shuddering at low RPMs, and intermittent shifting problems. These issues are noted at various mileage ranges, with some complaints occurring as early as 60,740 miles. Additionally, several owners mention a "Steering Assist is Reduced Drive with Care" message and check engine light illumination, which sometimes coincide with power loss or engine shutdowns. Safety implications include potential vehicle control challenges due to reduced steering assist and transmission performance issues, but no crashes or fires are reported. Buyers should be aware of these patterns and consider the potential need for repairs, especially as some problems persist even after multiple dealership visits.

BACK OVER PREVENTION

Owners report two primary issues with the 2020 Cadillac XT6 in the back over prevention category: problems with the rearview camera and unexpected braking while reversing. Complaints frequently mention the rearview camera failing intermittently, displaying a black screen with warning symbols, and often malfunctioning in cooler temperatures. This issue is noted at varying mileages, with one report at 16,572 miles. Additionally, some owners describe sudden, strong braking while reversing, particularly on downward slopes, without prior warning. These issues raise safety concerns due to the vehicle's blind spots and the potential for unexpected braking, which could lead to accidents.

ELECTRICAL SYSTEM

Owners report several recurring electrical system issues with the 2024 Cadillac XT6. Commonly described symptoms include the vehicle unexpectedly shutting down while driving, dashboard screens going blank, and instrument panels failing to display critical information. These issues often occur around 1,200 to 2,000 miles, with some owners experiencing a reoccurrence after attempted repairs. Safety implications are noted, such as the loss of control when the vehicle shuts down on highways and the potential for accidents due to non-functioning display panels and steering wheel seizure. Additionally, some owners report rearview camera malfunctions when reversing, indicated by error messages on the display.

UNKNOWN OR OTHER

Owners of the 2022 Cadillac XT6 report several mechanical and electrical issues, with a notable pattern involving sudden power loss while driving, which poses a safety risk due to the potential for loss of vehicle control. Complaints frequently mention dashboard lights flashing and the vehicle losing power, often linked to a faulty thermostat sensor, with some owners indicating this is a known issue at dealerships. Additional issues include dashboard panel warping in high temperatures and side mirrors failing to open automatically, requiring manual adjustment. There are also reports of sunroof shattering while driving, emphasizing the importance of keeping the sunscreen closed to prevent injury. These issues are reported at various mileages and can impact both safety and convenience, making them crucial considerations for potential buyers.

POWER TRAIN

Owners of the 2023 Cadillac XT6 report issues primarily related to power train malfunctions. A recurring problem involves delayed recall repairs due to unavailable parts, with multiple owners noting the manufacturer has not provided the necessary components within a reasonable timeframe. Additionally, some owners describe instances where the vehicle unexpectedly loses motive power, with one report noting this occurred at 64,000 miles. Another issue involves the vehicle moving forward when placed in reverse, posing a potential safety risk. These complaints highlight concerns about reliability and safety, particularly when the vehicle's behavior contradicts driver input.

BACK OVER PREVENTION

Owners of the 2021 Cadillac XT6 report recurring issues with the back-over prevention system, particularly with the rear-view camera. Complaints frequently mention the camera intermittently displaying a blank image or failing to show the correct surroundings while reversing. Some owners report messages like "Park Assist Block" appearing on the instrument panel, indicating sensor issues. These problems are noted at mileages ranging from approximately 7,000 to 33,000 miles. Although no accidents are reported, the failure to display accurate rear-view images presents a potential safety risk, especially when pedestrians are present. These issues are sometimes linked to a recall, but repairs are not always completed, as parts may be unavailable.

How to interpret the counts

Complaint totals are not failure rates

A popular or older model can accumulate more complaints simply because more vehicles exist and have spent longer on the road. The categories above aggregate the counts embedded in each model year's leading issues. Use recurrence across years and severity signals to decide what to inspect; use the VIN and a mechanical inspection to judge one car.

Source trail

Where this Cadillac XT6 data comes from

VinExposed combines model-level research with the vehicle-specific history you get from a VIN. Reliability scores and complaint patterns come from Auto Reliability Index's Cadillac XT6 research, which analyzes NHTSA records and independent repair data.

Recall counts describe a model year, not the repair status of one car. Confirm the exact VIN with the official NHTSA recall lookup and a vehicle-history report before buying.
