Fuel Tank Rollover Valve Seal Failure (AWD Models)
On 2022 XT5 AWD models, the fuel tank rollover valve may not provide a proper seal. In a rollover crash, fuel can leak from the tank, dramatically increasing the risk of fire. The valve may have become dislodged or was missing from the factory. This defect cannot be detected by the owner during normal driving.
NHTSA Recall N222366070. Dealers inspect the fuel tank and replace the fuel tank shell if the rollover valve is dislodged or missing. All repairs performed free of charge.
Est. Cost: $0 (recall repair)Left-Rear Suspension Toe Link Improperly Tightened
The left-rear suspension toe link fastener may not have been properly tightened during assembly. A loose toe link can cause rear wheel misalignment, uneven and rapid tire wear, wandering or pulling during highway driving, and in severe cases if the link separates, a sudden loss of directional control.
NHTSA Recall N222364330. Dealers inspect the left-rear suspension and tighten or replace the fastener if it is loose or missing. Free of charge.
Est. Cost: $0 (recall repair)9-Speed Transmission Shudder and Harsh Shifts
The 9-speed automatic transmission can develop shudder during light throttle acceleration, harsh shifts between gears, and hunting on grades. The condition is often most noticeable between 30-50 mph and can worsen over time as the transmission fluid degrades. Some owners report the transmission entering a limp mode.
Transmission fluid drain and fill with updated GM-specification fluid. TCM software update for improved shift calibration. Torque converter replacement for persistent shudder. Complete transmission replacement for internal failures covered under powertrain warranty.
Est. Cost: $300 (fluid service) - $4,500 (transmission replacement)Side View Mirror and Sunroof Defects
Owners report defective side view mirrors that vibrate excessively at highway speed, making them difficult to use, and auto-dimming mirror failures. Additionally, some owners have experienced the panoramic sunroof glass shattering spontaneously without any external impact, creating a loud bang and showering the cabin with glass fragments.
Replace vibrating or failed side view mirrors. For sunroof shattering, GM replaces the panoramic sunroof glass assembly under warranty. Document the incident with photos for warranty claims. Inspect the sunroof track and drainage system for proper operation.
Est. Cost: $300 (mirror) - $1,500 (sunroof glass replacement)Brake Pressure Modulator Valve Leak
The brake pressure modulator valve (BPMV) can develop an internal leak that reduces brake fluid pressure, resulting in diminished braking performance. The brake pedal may feel soft or travel farther than normal. The ABS warning light may illuminate. This issue affects multiple GM vehicles on the C1XX platform.
Reference NHTSA Recall 22V137000 for brake pressure modulator valve issues. Dealers replace the BPMV assembly and bleed the brake system. In some cases, the brake master cylinder may also need inspection and replacement.
Est. Cost: $0 (recall) - $1,200 (BPMV replacement out of recall)
