GM recall 14471 covers certain 2013-2015 XTS vehicles. The electronic parking-brake piston actuation arm may not fully retract, leaving the rear pads partially engaged without reliably illuminating the parking-brake indicator. This can cause poor acceleration, unwanted deceleration, excessive heat, smoke or sparks.
Common Symptoms
Poor acceleration or unwanted deceleration
Rear brake heat, smoke or sparks
Parking-brake indicator may not show the drag condition
How to Fix
Check the VIN for an open NHTSA 14V541 / GM 14471 campaign. If open, arrange dealer reprogramming of the electronic parking-brake control module at no charge. The recall remedy is software, not automatic actuator, switch or pad replacement, so the former parts links were removed.
GM safety recall 14062 covers 2013 and some 2014 XTS vehicles. A displaced cavity plug can let water enter and corrode the brake-booster pump relay connector; a resistive short can melt the connector and increase fire risk.
Common Symptoms
Open recall may exist without symptoms
Brake-booster pump connector corrosion
Melted connector or electrical odor
How to Fix
Check the VIN for an open NHTSA 14V116 / GM 14062 campaign. If open, arrange the dealer recall remedy, which includes sealing the cavity plugs, rerouting the vacuum-pump vent hose and replacing the affected front body harness when required. Do not purchase recall components from the former commerce links.
GM recall 13158B covers certain 2013 XTS vehicles that may intermittently flash the brake lamps without brake application and disengage cruise control, creating a misleading signal to following drivers.
Common Symptoms
Brake lamps flash without brake-pedal application
Cruise control disengages unexpectedly
How to Fix
Check the VIN for an open NHTSA 13V220 / GM 13158 campaign. If open, arrange dealer reprogramming of the body control module at no charge. No parts are required by the recall, so all former switch and module commerce links were removed.
The 2013-2019 XTS has the same CUE touchscreen delamination issue as all Cadillac CUE-equipped vehicles. The capacitive touchscreen develops bubbles, becomes unresponsive, or cracks from internal adhesive failure. The XTS was commonly used as a livery/fleet vehicle, and the CUE screen failure is widespread in the fleet community.
Common Symptoms
Screen appears bubbly or cloudy
Touch inputs not registering
Screen cracks without impact
Screen goes black intermittently
How to Fix
Replace CUE screen with OEM (GM 23106488) or aftermarket unit. Straightforward DIY.
XTS HID/Xenon headlamps suffer ballast (HID control unit) failures and headlight-housing condensation that cause intermittent or total loss of a low beam. Owners report flickering, a headlamp that cuts out then comes back, or a dead side after a new bulb. Moisture entering the housing is a frequent root cause — water reaching the ballast causes rapid failure — and corrosion in the headlight wiring/ground (often shared with the upper LED DRL) can take out both the ballast and DRL together.
Common Symptoms
One low-beam HID out or flickering
Headlight cuts out then comes back
Condensation/water inside headlamp
Upper DRL out on the same side
New bulb still doesn't fix it
Pinkish/dim HID color before failure
How to Fix
Diagnose by swapping the D3S bulb side-to-side; if the fault follows the position, the ballast/igniter is bad, not the bulb. Replace the failed HID ballast/control module and reseal the housing; dry out and re-gasket any housing showing condensation. Inspect the ballast connector and chassis ground for corrosion and repair before installing new parts, or the new ballast will fail again. Use OEM-grade D3S bulbs and a matching ballast to avoid color/flicker issues.
XTS owners frequently report the 12V battery going dead overnight or after a few days of sitting, caused by a control module failing to enter sleep mode and continuing to draw current with the ignition off. Common culprits on this platform include the radio/CUE (infotainment) module and the BCM. Repeated deep discharges then prematurely kill the battery and can trigger low-state-of-charge warnings and start-stop faults. GM issued service information for low-battery-state-of-charge conditions on 2018-2019 XTS/ATS/CTS.
Battery dead after sitting overnight or a few days
Repeated no-start / jump-start needed
Battery Saver Mode message
Low battery / reduced electrical features warnings
Start-stop system inoperative
How to Fix
Perform a parasitic-draw test (normal is under ~50mA once modules sleep, roughly 30-40 seconds after lockup) and pull-fuse isolation to find the circuit that stays awake. Common fixes include replacing/reflashing a faulty CUE/radio module or BCM, repairing a chattering switch/connector that wakes the bus, and removing non-OEM accessories (aftermarket LEDs are a documented trigger). Replace the battery if it has been repeatedly deep-cycled.
GM PI0890A covers 2013 XTS vehicles equipped with illuminated outside door handles RPO HD7 and built from June 18 through August 1, 2012. Water intrusion can corrode the button/light electronics, leaving a lock/unlock button or handle light inoperative.
Verify RPO HD7 and the build date before applying this bulletin. For an affected handle, follow current service information to replace the complete outside handle assembly and the cable for that door; GM specifically warns against replacing only the PCB insert. Use the electronic parts catalog for the exact painted handle rather than the former generic commerce links.
The front passenger seat contains a Passenger Presence System (occupant-classification sensor/module and wiring harness) that tells the airbag controller whether to enable the passenger airbag. On the XTS the sensor mat, the under-seat connector, and the wiring harness are prone to faults, illuminating the SRS/'Service Air Bag' warning and often leaving the PASSENGER AIRBAG OFF indicator stuck on (or incorrectly on with an adult seated). Because a fault can disable passenger airbag deployment, this is a genuine safety concern.
Passenger airbag indicator stuck OFF with adult seated
Passenger airbag status flickers
Airbag light on after seat work
How to Fix
Diagnose with a scan tool for airbag/occupant-classification codes. First inspect, reseat, and clean the under-seat connector and wiring harness (corroded/loose pins are the most common cause). If the sensor/pressure-mat or Passenger Presence Module itself has failed, replace it; in some cases the sensor is integrated into the seat cushion, raising cost. A post-repair occupant-classification recalibration may be required.
What you need to diagnose it
The repair instructions explicitly call for reading stored codes. Use a scanner that can read the named code families before choosing a repair.This issue involves B codes, which a basic engine-code reader cannot see.The recommended scanner supports these code families; confirm your exact year, model and module coverage before buying.

Reading and clearing the code is DIY work. Module replacement or reprogramming is not — most modules are VIN-programmed, so a new one does nothing until a shop codes it to your car. Check for an open recall or service bulletin before buying anything.
The Safety Alert Seat uses haptic (vibration) motors in the left and right seat bolsters to pulse warnings for lane departure, blind spot, and forward collision. One side commonly stops vibrating (left or right only), or the system randomly switches between vibrate and chime. The documented weak point is a wire breaking where it enters the haptic motor assembly. Because GM ties this hardware into the driver-assist suite, a failed seat motor frequently also triggers a 'Service Driver Assist System' message.
Lane-departure/blind-spot light flashes but no buzz
Inconsistent forward-collision haptic
How to Fix
Confirm the dead side by triggering lane-departure to each side; if only one bolster pulses, the opposite motor/wire has failed. Replace the affected seat haptic vibration motor (left or right bumper-alert motor) and repair the broken wire at the motor entry. If the seat hardware checks out, scan the BCM for driver-assist codes and update software, since a glitch can mimic the failure. As a stopgap, owners can switch Alert Type to 'beeps' in the menu to restore audible warnings.
XTS models equipped with the optional rear air-leveling suspension (RPO F38) suffer sudden, total collapse of the rear air springs/struts, often without warning and sometimes at highway speed. NHTSA/CarComplaints reports describe the rear dropping so low the tires nearly contact the wheel wells, causing the rear end to bounce and loss of vehicle control. Root causes include failed rear air springs (perforation/dry-rot), a worn-out air dryer/desiccant that lets moisture accumulate, and air compressor/air-line failures. A 'Service Leveling System' message and the car sitting low or unlevel are the early warning signs. The 2013 model year alone shows ~24 logged suspension complaints, the highest-volume XTS problem after CUE.
Rear end suddenly drops/sags, tires near wheel wells
Service Leveling System warning message
Car sits low or unlevel at rest
Air compressor runs constantly or not at all
Rear bouncing / loss of control over bumps
Hissing air leak from rear
How to Fix
Diagnose with a scan tool for leveling-system codes and a smoke/soap test of the air springs and lines. Replace failed rear air springs/struts and the air supply unit (compressor with integrated dryer). Many owners with repeat failures convert to a passive coil-spring/strut conversion kit (Strutmasters/Arnott) to permanently eliminate the air system. Always replace the air dryer/desiccant when servicing the compressor or moisture will quickly kill the new unit. OEM compressor assembly PN 84355910 (ACDelco 22956965); Arnott aftermarket compressor and spring kits are common cross-references.
What you need to diagnose it
The repair instructions explicitly call for reading stored codes. Use a scanner that can read the named code families before choosing a repair.This issue involves C codes, which a basic engine-code reader cannot see.The recommended scanner supports these code families; confirm your exact year, model and module coverage before buying.

GM PI1285 covers 2013-2015 XTS rear shocks when light oil seepage or a clunk over bumps is reported. A light oil film is not proof of failure; GM directs checking for a substantial leak and inspecting whether the upper mount shifted because its bolts or suspension-control software need correction.
Common Symptoms
Light oil residue on a rear shock
Rear suspension clunk over bumps
How to Fix
Have the rear suspension inspected under current GM procedures. Do not replace a shock for light seepage alone. If the upper mount shifted, check and torque the mounting bolts to the bulletin specification and verify the Electronic Suspension Control Module calibration. Replace a shock only when diagnosis confirms an actual failure.
The engine-mounted high-pressure fuel pump (HPFP) on the GM 3.6L direct-injection V6 is a known wear item that fails on the XTS, causing long crank/no-start (especially warm restart), rough idle, stalling and misfires. The most common codes are P0087 (fuel rail pressure too low), P0089 (fuel pressure regulator performance) and P0191 (rail pressure sensor), often with random misfire P0300. Because the high-pressure pump is cam-driven off the engine, a failing pump can drive adaptive fuel trims that mask early symptoms until it strands the car.
Perform a live high-side fuel-pressure test during acceleration and on a warm restart to confirm the HPFP versus injectors or the low-pressure (in-tank) pump. Replace the high-pressure fuel pump and its sealing/lifter components; many shops also replace the camshaft pump-drive lifter and inspect the lobe. Use fresh GM-spec fuel-system sealant and torque to spec to avoid leaks. OEM HPFP PN 12641740 (supersedes 12622475; aftermarket Delphi HM10007 / GDP106 cross-references). Reset fuel trims after the repair.
The 3.6L V6 water pump develops an internal seal failure that lets coolant seep from the pump's weep hole — a designed indicator that the pump's internal shaft seal has failed. Owners commonly mistake the weep-hole drip for a 'pinhole' and try stop-leak, but it signals the pump is failing internally and will progress to overheating and potential head-gasket/engine damage. Low-coolant warnings, sweet smell, and white residue at the front of the engine are typical. RepairPal lists coolant leaks (pump, hoses, radiator) among the most common XTS cooling complaints.
Confirm the source: clean the area and look for fresh coolant tracking from the weep hole below the water pump pulley (versus hose clamps or the radiator). Replace the water pump with a new OEM/ACDelco unit and gasket, refill with DEX-COOL, and pressure-test. Do NOT use stop-leak — it can clog the heater core and radiator. ACDelco Gold water pump PN 19325605 (aftermarket ACDelco 252-962 cross-reference); inspect the thermostat and upper/lower hoses while the system is open.

GM PIP3423P covers 2013-2019 XTS vehicles with the 3.6L LFX or LF3 engine when two or more of P0008, P0009 and P0016-P0019 are present. GM directs technicians to check for loose chains or tensioners and, if normal SI diagnosis does not find the cause, inspect whether the crankshaft-sensor reluctor moved. The bulletin does not establish automatic chain replacement.
Check-engine light with two or more correlation DTCs
P0008 or P0009
P0016 through P0019
How to Fix
Have a qualified technician confirm that at least two listed correlation DTCs are present, then follow current SI diagnosis for chains and tensioners. If the cause remains unresolved, inspect the crankshaft reluctor as directed by PIP3423P. Do not order the former generic timing kit or water pump from this card; the exact ShowMeTheParts lookup returned no timing-chain candidate.
The 3.6L V6 (LFX naturally-aspirated and LF3 twin-turbo) uses direct fuel injection, so no fuel washes over the backs of the intake valves. Combined with a PCV system that routes oil vapor into the intake tract, carbon coking accumulates on the intake valves over time. By roughly 60,000-100,000 miles this can cause rough idle, misfires, hesitation, and reduced fuel economy/power. This is separate from timing-chain-stretch and high-pressure fuel-pump issues; it is a fueling/airflow deposit problem inherent to GDI engines.
Clean the intake valves by walnut-shell media blasting (the accepted fix for GDI coking); chemical intake cleaners help mildly but do not remove hardened deposits. To slow recurrence, install an oil catch can on the PCV line and/or a reduced-orifice PCV to keep oil vapor out of the intake. Periodic top-end cleaning is preventive maintenance on these DI engines.
GM PI1294B covers 2014-2016 XTS vehicles with belt-drive electronic power steering RPO NJ2 when a Service Power Steering message appears intermittently after a cold start and C056D 3C, C0475 00 or U0131 is current or stored.
Intermittent Service Power Steering message after a cold start
C056D 3C
C0475 00
U0131
How to Fix
Have a qualified technician verify RPO NJ2 and the exact DTC subtypes, inspect the G111 ground and XTS 80A F72UA fuse connections, fully charge and test the battery, then update the power-steering control module under current GM programming procedures. Do not replace the steering gear, module or battery solely from this card.
The XTS dual-panel sunroof is prone to water intrusion that stains the cloth headliner and wets the front/rear passenger footwells. The design uses the same perimeter seal on the fixed glass as the moving panel (doubling leak-off) with undersized drain tubes that clog easily with debris, overwhelming the system in heavy rain. The problem became significant enough that Cadillac faced a class-action lawsuit over leaking sunroofs across several models. Water can also reach electrical modules under the carpet, causing secondary electrical faults.
Common Symptoms
Water dripping onto headliner or A-pillar
Stained/sagging cloth headliner
Wet front or rear floor carpet
Musty/damp smell in cabin
Water sloshing sound in roof/pillars
Fogged windows
How to Fix
Flush all four sunroof drain tubes with low-pressure compressed air or a flexible trimmer line (avoid stiff wire that can pop the hose off at the bottom). Verify water exits at the rocker/A-pillar and rear quarter outlets. Replace cracked/age-hardened sunroof perimeter gaskets and reseat the drain hose grommets; in stubborn cases seal the leaking drain-tube connection. Dry and replace stained headliner/insulation and check for wet carpet over body control modules.
GM bulletin 18-NA-358 covers 2014-2019 XTS vehicles with 6T70, 6T75 or 6T80 transmissions RPO M7U, M7W, M7V or MHM when severe launch or fourth-gear shudder, a 2-3 upshift or 3-2 downshift concern, flare, slip or harsh shift is present. Debris or scoring in the upper or lower valve body may be involved, but GM first requires ruling out engine driveability and torque-converter clutch shudder.
Common Symptoms
Severe shudder during launch in first gear
Shudder in fourth gear
2-3 upshift or 3-2 downshift shudder
Flare, slide/bump, slip or harsh shift
How to Fix
Have a qualified transmission technician verify the transmission RPO, reproduce the exact event and monitor TCC slip. Do not replace the TEHCM for this symptom. If diagnosis confirms the bulletin valve-body condition, follow current SI for both upper and lower valve-body replacement. Do not use a universal fluid or additive; the exact ShowMeTheParts lookup returned no transmission-fluid candidate.
Two related HVAC complaints are common on the XTS: a repetitive clicking/knocking from behind the dash caused by a failing blend-door (temperature) actuator that can't reach its calibration stop, and loss of fan-speed control or no heat from a failed blower motor resistor/module — when the resistor fails the fan often works only on the highest setting. Owners report inconsistent temperature (one side hot/one cold) with the actuator fault and a dead or single-speed blower with the resistor fault.
For the clicking: identify the failing blend-door actuator (listen/feel behind the dash while cycling temperature), replace the actuator and re-run the HVAC calibration/relearn. For no/limited fan: test the blower motor resistor/control module and the blower motor itself; replace the failed resistor module (and motor if it's drawing high current). Clear any HVAC actuator codes after replacement.
