On the 2020-2023 Cadillac XT6, xT6 owners report a "Steering Assist is Reduced — Drive with Care" or "Service Power Steering" message in the driver information center, usually with a noticeable increase in steering effort. GM bulletin 20-NA-215 covers this condition on the XT5 and XT6 and ties it to DTCs C0460 and/or C0545 stored in the power steering module. The XT6 uses a belt-drive electric rack with the motor and control module integrated into the steering gear, so an internal fault or a torque-sensor signal fault sets the code and the module deliberately cuts or reduces assist rather than allowing erratic assist. Steering is still mechanically connected — the car remains steerable — but effort rises sharply, which is most alarming at parking-lot speeds or in an evasive maneuver. Owners also describe a separate, milder version where assist fades after sustained low-speed maneuvering and returns once the system cools; that thermal derate is normal protection, not a failed rack, and it clears itself.

This issue also affects: Chevrolet HHR, Chevrolet Malibu, Chevrolet Silverado 1500

Common Symptoms

  • "Steering Assist is Reduced — Drive with Care" message in the DIC
  • "Service Power Steering" warning
  • Steering suddenly becomes very heavy, especially at parking speeds
  • Assist cuts out intermittently and returns after a restart
  • Sometimes accompanied by other electrical warnings on the same drive

How to Fix

Have the power steering module scanned first. A stored C0460 or C0545 per bulletin 20-NA-215 calls for replacement of the complete steering gear assembly — the module is not serviced separately. After the rack is replaced the steering angle sensor must be recalibrated with a capable scan tool or the system will not function and the message will return. Out of warranty a rack and calibration typically runs roughly $1,500-$2,600 at a dealer. Before replacing anything, rule out the thermal derate (assist returns after cooling, no stored code) and a weak battery or poor ground, either of which can trigger a false assist-reduced message on this platform. The XT6's powertrain warranty does not cover this, but the 4-year/50,000-mile bumper-to-bumper coverage does.

Typical repair cost:$1,500 - $2,600

On the 2022 Cadillac XT6, if you drive a 2022 Cadillac XT6, check this one. General Motors recalled a group of these SUVs after finding that the left-rear suspension toe link may not have been tightened properly. An under-tightened fastener can allow the toe link to go loose over time, and a loose toe link can separate outright. GM's stated consequence is blunt: separation can cause a loss of vehicle control and increases the risk of a crash. NHTSA logged the campaign as 22V427000 in the SUSPENSION:REAR component group; GM's own number for it is N222364330. The 2022 Cadillac XT5 and 2022 GMC Acadia are covered by the same campaign. NHTSA's record does not state how many vehicles were affected campaign-wide.

Common Symptoms

  • Loose left-rear suspension toe link
  • Toe link separation
  • Loss of vehicle control

How to Fix

The fix costs the owner nothing. A Cadillac dealer inspects the left-rear suspension and replaces the fastener if it turns out to be loose or missing. Notification letters went out to owners on July 11, 2022, so if you bought the vehicle used you may never have seen one — enter your VIN at nhtsa.gov/recalls to see whether your XT6 is on the list and whether the repair is still open. Cadillac customer service is 1-800-458-8006, recall N222364330.

On the 2022 Cadillac XT6, certain 2022 Cadillac XT6 crossovers were recalled by General Motors for a fuel tank rollover valve that may not seal properly in a rollover crash. NHTSA files the defect against the gasoline storage tank assembly. The rollover valve's whole purpose is to shut the tank's vent path when the XT6 is no longer upright, keeping gasoline inside the tank rather than letting it run out through the vent. On the recalled vehicles the valve can be dislodged from its position or absent altogether, which leaves nothing to close that path. GM's stated consequence is direct: fuel can leak during a rollover crash, and that raises the risk of a fire. This is not a drivability problem — the XT6 runs and refuels normally with the defect present, which is exactly why it is worth confirming by VIN rather than waiting to notice something wrong.

How to Fix

Correction is free of charge at a Cadillac dealer under NHTSA campaign 22V446000, GM number N222366070. The dealer inspects the fuel tank and replaces the fuel tank shell if the rollover valve turns out to be dislodged or missing; if the valve is properly in place, no replacement is needed. Owner letters went out July 27, 2022. Check your VIN at nhtsa.gov/recalls to see whether the remedy has been performed, and call Cadillac customer service at 1-800-458-8006 with questions.

On the 2020-2023 Cadillac XT6, the XT6's GM 9T65 9-speed automatic transmission exhibits shuddering during light throttle acceleration between 25-50 mph, similar to driving over rumble strips. The torque converter clutch wears prematurely, contaminating the transmission fluid.

This issue also affects: Buick Encore GX, Buick Regal, Cadillac DeVille

Common Symptoms

  • Shuddering at 25-50 mph
  • Vibration during light acceleration
  • Harsh 1-2 shift
  • Transmission hesitation
  • Feels like driving over rumble strips
  • Shudder worse when transmission is warm

How to Fix

A transmission fluid flush with the updated Mobil 1 Blue Label fluid resolves mild cases. Severe cases require torque converter replacement. A GM TSB authorizes fluid flush as the first repair attempt.

Typical repair cost:$150 - $2,500

On the 2020-2025 Cadillac XT6, the Power Transfer Unit (PTU) on AWD-equipped XT6 models develops seal leaks that allow fluid to seep out. Low PTU fluid causes the internal gears and bearings to wear prematurely, eventually producing a whining noise. The PTU is not included in routine maintenance schedules, so leaks often go unnoticed.

This issue also affects: Cadillac SRX

Common Symptoms

  • Fluid leak near front of transmission
  • Whining noise from front drivetrain
  • AWD malfunction warning
  • Oil spots on driveway

How to Fix

Inspect the PTU seals and replace if leaking. Top off with the GM-specified PTU fluid. If the PTU is already noisy from running low on fluid, replacement is required as the unit is not rebuildable. Add PTU fluid level check to your routine maintenance schedule every 15,000 miles.

Typical repair cost:$200 - $2,000

On the 2020-2025 Cadillac XT6, the XT6 uses the GM 3.6L V6 (LGX) which has a documented history of timing chain stretch across the GM lineup. While the LGX generation is improved over earlier 3.6L variants, the three-chain design with plastic guides remains a long-term reliability concern. Most XT6s are still too new for widespread timing chain failures, but owners should monitor for early signs and plan for preventive replacement around 100,000-120,000 miles based on the engine's history in other models.

This issue also affects: Buick Cascada, Buick Enclave, Buick Encore

Common Symptoms

  • Rattling on cold start that goes away when warm
  • Check engine light with timing correlation codes at higher mileage
  • Rough idle developing gradually

How to Fix

Monitor for timing chain rattle on cold starts. If codes or rattle develop, complete timing chain replacement is needed. Preventive replacement at 100,000-120,000 miles is wise based on the 3.6L's track record. Same Cloyes 9-0753S kit as other 3.6L applications.

Typical repair cost:$2,500 - $4,500

On the 2020-2025 Cadillac XT6, the auto start-stop system engages and disengages harshly, causing the vehicle to shudder on restart. The AGM battery required for the system degrades quickly, and when it weakens, the start-stop system becomes erratic or disables itself. Many owners find the system intrusive.

This issue also affects: Buick LaCrosse, Buick Regal, Chevrolet Cruze

Common Symptoms

  • Harsh restart vibration
  • Start-stop not functioning
  • Battery warning message
  • Multiple systems acting erratic
  • Slow cranking on restart

How to Fix

Replace the AGM battery with a fresh ACDelco unit if the system is not functioning properly. Have the battery monitor sensor reset after replacement. GM has released recalibrations to improve start-stop smoothness. Aftermarket start-stop eliminator modules are available for owners who want to permanently disable the feature.

On the 2020-2022 Cadillac XT6, gM bulletin 22-NA-094, issued July 2022, addresses a loss of cabin heat on the Cadillac XT6 and XT5. Owners get little or no warm air from the vents even after the engine reaches operating temperature — the complaint typically shows up in cold weather and is easy to misdiagnose as a stuck thermostat, an air pocket in the cooling system, a blend door actuator, or a plugged heater core. GM traced it instead to a software anomaly in the engine control module: the ECM's thermal management strategy does not bring coolant temperature up or route flow to the heater core as intended, so the heater has nothing hot to work with. Because the fault is calibration rather than hardware, no part is actually broken, and owners who let a shop chase it mechanically can spend hundreds of dollars replacing a perfectly good thermostat or heater core before the real fix is applied.

Common Symptoms

  • Little or no heat from the vents in cold weather
  • Cabin takes an unusually long time to warm up, or never does
  • Engine coolant temperature gauge reads normal while the vents blow cool
  • Heat is intermittent — works on some drives and not others

How to Fix

The fix is a reprogram, not a part. Per bulletin 22-NA-094, the correction is to reprogram the engine control module with the updated calibration; this is a dealer or capable-shop operation using GM's programming tools and takes about an hour. Ask specifically for bulletin 22-NA-094 by number. Before authorizing a thermostat or heater core replacement for a no-heat complaint on an XT6, confirm the ECM calibration is current — under the 4-year/50,000-mile bumper-to-bumper warranty the reprogram is free, and even out of warranty it typically runs $100-$200 against $600-$1,400 for a heater core job that would not have fixed it.

Typical repair cost:$0 - $200
