NHTSA Owner Complaint Log
This page lists owner-reported complaints filed with NHTSA for the 2018 Lexus GS. Complaints are unverified consumer reports submitted to NHTSA and do not by themselves prove a defect or defect rate.
The contact owns a 2018 Lexus GS350. The contact stated while the vehicle was parked, the windshield cracked without impact. The vehicle was taken to an independent mechanic and the contact was informed that the failure was due to a defect in the windshield being glued on one side. The windshield had been repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 79,000.
While A/C is on, passenger side AC vent is blowing warm air while driver side and back seat AC vents are blowing cold air. Lowering the cabin air temperature controls do not correct the issue. It makes the car temperature get hot and uncomfortable, which becomes distracting when driving.
