RTV Sealant Clogging Oil Pan Pickup
Excess RTV sealant used during engine assembly clogs the oil pickup tube in the oil pan, causing oil starvation. This is the most critical and commonly reported issue, representing over 87% of NHTSA complaints. Oil starvation can destroy engine bearings, pistons, and the crankshaft.
Oil pan removal and cleaning of the oil pickup screen to remove RTV debris. In advanced cases where engine damage has occurred, a short block or complete engine replacement is necessary. Document oil pressure readings for warranty claims.
Est. Cost: $500 - $8,000+Sunroof Spontaneous Shattering
The panoramic sunroof glass shatters spontaneously without any impact, sending glass fragments into the cabin. Owners report hearing a loud pop followed by the sunroof cracking into thousands of pieces while driving or parked.
Complete sunroof glass assembly replacement. Subaru may cover this under warranty or goodwill if it occurs without an impact event. Document the condition with photos immediately for warranty claims.
Est. Cost: $0 (warranty) / $800 - $1,500 if out of warrantyBrake Pedal Click with Auto Vehicle Hold (AVH)
The brake pedal produces a clicking or popping noise when the Auto Vehicle Hold (AVH) system is activated. The noise occurs each time the system engages or disengages at stops and is audible and tactile through the pedal.
A Subaru TSB addresses the AVH brake pedal click with a software calibration update to the brake system control module. The update adjusts the AVH engagement characteristics to reduce the audible click.
Est. Cost: $0 - $150EyeSight Owner's Manual Error (High Beam Assist)
The owner's manual contains incorrect instructions for adjusting the sensitivity of the High Beam Assist function, failing to comply with FMVSS 108. Following the incorrect instructions could result in improper headlight beam operation.
Subaru issued a recall with updated owner's manual pages. Dealer will provide corrected manual inserts and verify High Beam Assist is functioning correctly. Owner notification letters were mailed February 2023.
Est. Cost: $0 (recall)EVAP Purge Control Valve Malfunction
The EVAP purge control valve may malfunction, causing a check engine light with evaporative emission DTCs. This can also cause rough idle on cold starts, fuel smell in the cabin, and difficulty refueling as the tank does not vent properly.
A Subaru TSB addresses the EVAP purge control valve issue with ECM reprogramming and valve replacement if needed. The repair is typically covered under the federal emissions warranty.
Est. Cost: $0 (warranty) / $200 - $500 if out of warranty
