Integra Type S·DE5·20232025·2,356 cc

"The K20C1 is a proven performance base, but the Integra Type S is young enough that long-term data is still thin — steering recall and amplifier failures are the early red flags to watch."

Known Issues
Sticky Steering Rack / Loss of Control€1,200-3,500 · 0-30,000 kmCRITICAL

Multiple NHTSA complaints report sticky, unpredictable steering that can result in loss of vehicle control. A recall was issued, but some owners report the initial fix (grease application) was insufficient and the problem returned, requiring full steering rack replacement.

Steering feels sticky or notchy at low speed
Unexpected steering resistance during cornering
Vehicle pulls or deviates unexpectedly
Issue recurring after dealer repair
DIY: Hard
ABS/Traction Control Module Recall — Brake Valve Defect€0 (recall covered) · 0-50,000 kmHIGH

Honda recalled certain 2023 Acura Integra vehicles due to a faulty ball valve in the ABS/traction control unit. This can compromise braking performance and stability control, posing a significant safety risk.

Reduced braking effectiveness
Traction control malfunction warning
DIY: Not DIY — dealer only
Phantom Braking — Adaptive Cruise Control False Activation€200-800 · 0-40,000 kmHIGH

NHTSA complaints document the adaptive cruise control system commanding hard braking at freeway speeds with no obstacle present. Dashboard sensors show no vehicles nearby during these events, suggesting a sensor calibration or software fault.

Sudden hard braking at highway speed with no vehicle ahead
ADAS system shows clear road before braking event
Repeated occurrences on same vehicle
DIY: Not DIY — dealer software update required
Audio Amplifier Failure€1,500-2,500 · 10,000-60,000 kmMODERATE

Multiple NHTSA complaints describe the premium audio amplifier failing completely, resulting in total loss of sound. Dealer replacement costs reported around €2,000. The pattern across multiple owners suggests a systemic component weakness rather than isolated incidents.

Complete loss of audio from all speakers
Display and radio controls still function normally
No warning prior to failure
DIY: Moderate

Buying Checklist
Run the VIN on NHTSA's recall database and confirm both the steering rack and ABS module recalls have been completed with full replacement, not temporary fixes
During test drive, perform multiple low-speed steering inputs and full-lock maneuvers to feel for any stickiness or resistance in the steering rack
Test adaptive cruise control on a highway stretch to verify it does not trigger phantom braking events
Activate all audio zones and speaker positions — confirm amplifier is functioning fully with no dropout
Request full documented service history and verify oil changes were performed at or below 8,000 km intervals with correct Honda-spec full synthetic
Inspect engine bay for any turbocharger oil seepage, boost pipe condition, and intercooler integrity, especially on higher-mileage examples

Buying Advice

The Acura Integra Type S carries a well-regarded K20C1 engine with a proven mechanical foundation, but being a 2023-onwards model means long-term reliability data is still limited. The two active recalls — particularly the steering rack issue — are serious and must be verified as fully resolved before any purchase, since a grease-only fix is not acceptable. Budget for potential amplifier replacement outside warranty, and prefer examples with documented, frequent oil changes given the turbocharged application. At this stage, buying a certified pre-owned example with remaining factory warranty is the smartest way to manage early-ownership risk.
