Cadillac XT5 Problems by year

StabiliTrak A General Motors authorized Cadillac dealership has diagnosed the problem as a failure of the brake control module. Of particular concern, the GM dealership informed me that it has been unable to locate a replacement part, even after conducting a nationwide search of GM parts as well as after-market parts sources. This seems very unacceptable. This situation raises two significant concerns: 1.A malfunction involving an essential electronic braking and vehicle stability-control component may compromise vehicle safety. 2.An owner of a relatively low-mileage vehicle (approximately 70,000 miles) may be unable to obtain a necessary safety-related repair because the manufacturer cannot locate the replacement component. I am concerned about the safety implications for myself and other owners of 2017 Cadillac XT5 vehicles who may experience the same failure. I respectfully request that NHTSA: •Review reported failures involving the electronic brake control module in 2017 Cadillac XT5 vehicles. •Determine whether similar failures have been reported by other owners. •Investigate whether this condition represents a potential safety-related defect. •Examine the availability of replacement brake control modules and the impact on owners who cannot obtain necessary repairs. •Determine whether further manufacturer action, including a safety recall or other corrective action, is warranted.

evasive maneuver, especially at low speeds where pedestrian and parking-lot conflicts occur. Suspected root cause per owner reports and GM service documentation: engine coolant thermostat failure triggers a false engine temperature signal, and the electric power steering system reduces assist as a thermal protection response. Companion symptoms reported: inoperative/incorrect temperature gauge, cooling fans running at high speed continuously, A/C performance loss, DTC P0128. Manufacturer documents: Cadillac Service Bulletin 20NA215 (corrects "Steering Assist is Reduced Drive with Care" on 2021 XT5); GM Service Bulletin 17-NA-284 (2017-2018 XT5/GMC Acadia, reduced steering assist message with DTC C0460 Sym 5A, steering angle sensor trim error); GM Special Coverage N252508350 for the engine coolant thermostat (15 years/150,635 miles, expiring March 1, 2036). The vehicle carries a rebuilt title, so GM's warranty block applies and the owner may be denied the special-coverage remedy that a safety recall would guarantee to all owners regardless of title status.

"Steering Assist Is Reduced - Drive With Care" warning and a check-engine light. The steering felt normal despite the warning; I am not claiming an actual loss of steering. The temperature gauge has remained on cold, and the air conditioning has malfunctioned. The exact date the steering warning first appeared is UNKNOWN. On October 21, 2026, another Chevrolet dealership documented diagnostic code P0128 and recommended thermostat/coolant-temperature-related repairs. Those repairs have not been performed. The manufacturer was contacted and declined repair assistance. Dealerships have inspected the vehicle; I am not aware of a separate inspection by the manufacturer. I am concerned about the persistent shuddering at highway speeds and the warning of potentially reduced steering assistance. The cause of the shuddering and its relationship, if any, to the other symptoms remain unconfirmed. I still have the vehicle. Repair records, diagnostic information, and photographs of warning messages are available.

damage or failed LEDs. My primary concern is vehicle safety. An intermittent malfunction of a rear turn signal may prevent motorists behind me from receiving a reliable indication of my intention to turn or change lanes, creating a potential collision hazard. There is also a significant secondary safety concern involving the vehicle's Driver Information Center (DIC). When the "Left Rear Turn Indicator Failure" warning appears, an unusually large notification occupies most of the central instrument display, obscuring the digital vehicle speed readout and other driver information normally displayed in that area. This creates an additional safety concern because the driver cannot readily see the digital speed reading while the warning is displayed. The notification may also distract the driver when it appears unexpectedly during operation. I have included a photograph documenting the warning and its obstruction of the instrument display. The repair is not covered under GM's factory warranty. Additionally, the third-party extended service contract purchased and provided by the selling Cadillac dealership denied coverage, classifying the problem as a bulb-related failure despite the vehicle using an integrated LED lamp assembly. The substantial replacement cost may discourage owners from promptly repairing a malfunction involving an important vehicle safety component.
