The daytime running lights (DRLs) may not deactivate when the headlights are on. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
SUSPENSION:REAR
General Motors, LLC (GM) is recalling certain 2023 Cadillac Escalade, Escalade ESV, Chevrolet Suburban, Chevrolet Tahoe, GMC Yukon, and Yukon XL vehicles. The rear suspension outer control arm bolts may not have been properly heat-treated, which can cause the bolts to break.
STEERING:STEERING CONTROL MODULE
General Motors, LLC (GM) is recalling certain 2021 Cadillac Escalade, Escalade ESV, Chevrolet Suburban, Chevrolet Tahoe, GMC Yukon, and Yukon XL vehicles. A software issue may cause a loss of power steering assist at startup or while driving.
POWER TRAIN:DRIVELINE:DRIVESHAFT
General Motors, LLC (GM) is recalling certain 2021 GMC Yukon, Yukon XL, Cadillac Escalade, Escalade ESV, Chevrolet Suburban, and Chevrolet Tahoe vehicles. The rear wheel driveshaft assemblies may have internal components that were not heat-treated properly, possibly resulting in driveshaft failure.

The most frequently reported are: Reduced Engine Power / Throttle Body (TAC) Failure, 4L60E Transmission 3-4 Clutch Failure / Loss of 3rd & 4th, Instrument Cluster Gauge Failure (Stepper Motor). Of these, 3 are rated critical and should be addressed promptly.
The 2004 Chevrolet Suburban has 12 known issues compiled from NHTSA recalls, manufacturer TSBs, and owner forum reports. 3 issues are rated critical: Reduced Engine Power / Throttle Body (TAC) Failure and 4L60E Transmission 3-4 Clutch Failure / Loss of 3rd & 4th and Instrument Cluster Gauge Failure (Stepper Motor). Prospective buyers should inspect for these issues and factor potential repair costs into their purchase decision. Regular maintenance following the manufacturer's schedule helps prevent many common problems.
Repair costs for known Chevrolet Suburban issues range from $0 to $3,500, depending on the specific problem and whether you choose DIY or professional repair. The most critical issue, Reduced Engine Power / Throttle Body (TAC) Failure, typically costs $200-$500 to repair. Au7o provides step-by-step DIY maintenance guides that can help reduce repair costs.
The electronic (drive-by-wire) throttle system triggers a 'Reduced Engine Power' / 'Engine Power Is Reduced' limp mode that sharply limits acceleration and speed - dangerous when it strikes in traffic. The cause is usually the throttle actuator control (TAC): worn internal thrott… Repairs typically run $200-$500. Severity: high.
The 4L60E automatic behind the half-ton Suburban is notorious for burning up the 3-4 clutch pack. The 3-4 apply circuit is long and loses pressure as valve-body bores wear, so the clutches overheat and glaze. Symptoms are slipping in 3rd/4th, a jump from 2nd straight to 4th, or a… Repairs typically run $1,500-$3,500. Severity: high.
The 2003-2006 (GMT800) analog cluster uses tiny Switec/Juken X27.168 stepper motors to drive each gauge needle. These motors wear and lose steps, so the speedometer, tachometer, fuel, and temperature gauges stick, read wildly wrong, sweep erratically, or drop to zero while drivin… Repairs typically run $150-$400. Severity: high.
The Gen III/IV LS-based Vortec V8s use a plastic (nylon) intake manifold with molded silicone/rubber gaskets. With heat cycling and age the gaskets harden and crack, creating an unmetered vacuum leak that leans out the mixture and can weep oil at the manifold-to-head sealing surf… Repairs typically run $250-$650. Severity: medium.
The exhaust manifold retaining bolts fatigue and snap from repeated heat-cycling on the Vortec V8s. As clamp load is lost the manifold-to-head seal leaks, producing a ticking/chuffing 'exhaust leak' noise that is loudest on cold start and quiets as the metal expands and warms. Ow… Repairs typically run $200-$700. Severity: medium.
The sealed front wheel bearing/hub assemblies on 4WD Suburbans wear out and are a top high-mileage complaint. Because the ABS wheel-speed sensor is integrated into the hub, a failing bearing (or a failed sensor) commonly triggers the ABS and traction/StabiliTrak warning lights al… Repairs typically run $150-$450. Severity: medium.
The transfer case on the 4WD Suburban develops fluid leaks from the front and rear output shaft seals, the input shaft seal, or the case halves where the case splits. The NP246 (half-ton) and NP261/NP263 (heavy-duty) transfer cases all share this tendency. Low transfer case fluid… Repairs typically run $50-$1,000. Severity: medium.
The in-tank fuel level sending unit reads incorrectly on these Suburbans - the gauge sticks, bounces, reads full or empty regardless of actual level, or drops to E with a low-fuel light on a full tank. The failure is the sensor card/wiper: aggressive sulfur and ethanol in modern… Repairs typically run $150-$450. Severity: medium.
The plastic gears inside the HVAC blend/mode door actuators strip out, so the door can't move. The classic symptom is a repetitive clicking or tapping from behind the dash (near the glovebox/center) when starting the truck or changing temperature, plus one side blowing hot while… Repairs typically run $80-$250. Severity: low.
A widely reported clunk/knock felt in the steering wheel and column, most noticeable turning at low speed over bumps or during small back-and-forth steering inputs. The telescoping upper intermediate steering shaft loses its internal lubrication and the splines take up play with… Repairs typically run $80-$250. Severity: low.
Early GMT800 Vortec V8s are known for cold-start 'piston slap' - a brief knock/rattle for the first several seconds to a minute after a cold start that fades as the engine warms. The early LS-series pistons had short skirts and extra bore clearance, so the piston rocks in the cyl… Repairs typically run $0-$300. Severity: low.
On Gen III/IV Vortec V8s the two knock sensors sit in the lifter valley beneath the intake manifold, under a plastic cover. Water and debris collect in the valley and corrode the sensor connectors and wiring; the factory connectors also embrittle from heat. The result is an inter… Repairs typically run $250-$500. Severity: low.
