“When I signed a purchase order on 5/10/08, the odometer disclosure statement was 6225 miles. Jackson Volvo service at hilo did not give me the copy of odometer disclosure statement. It was delivered on 5/12/2008. Then the odometer disclosure statement showed 106,225 miles. The A/C also became very polluted.”
NHTSA complaint #10242107, filed 2008-09, 6,225 miles“My 1 1/2 years old Volvo S40 did this twice, shortly after starting it and moving it for a couple of miles. It displayed the message brake failure stop car safely , anti-skid system failure , reduced engine performance . The car could not go more than 15 MPH. After parking it, I could not restart the engine and the messages kept repeating in random order. The first time that I took it to the dealer they said that they changed the computer message module (the mechanic carried a box with many plugs in it, just to show me what it looked like). But just after 500 miles, the problem re-appeared. …”

NHTSA complaint #10676796, filed 2015-01, 89,000 miles“The contact owns a 2006 Volvo S40. While driving at any speed, the air condition emits hot air. The failure occurs while the air conditioner is set at 65 degrees. The outside temperature gauge was replaced, but that did not remedy the failure. The vehicle has been taken to two dealers on approximately twelve occasions. The vehicle still has not been properly repaired. The current mileage was 3,100 and failure mileage was 500.”
