Suspension
14 reports1 crash
“My issues are related to the SAFETY RECALL CAMPAIGN 1997-2003 QX4 IN SALT STATES FRONT STRUT HOUSING CORROSION. I brought my car in for the recall at Infiniti of Bloomington, Minnesota and they only fixed the Driver’s side strut housing using a brace but only painted the Passenger’s side. Now the Passenger’s side strut housing shows corrosion and some perforation but repairable still under the recall. As of today 01/23/2023 The dealer and Infiniti refused to do recall on passenger’s side despite the car is not safe to drive. They knowingly know the passenger’s side will corrode but still let me drive the car with the defective which they refuse to fix.”
