Issue: This recall is for aftermarket replacement rear window glass produced by Vitro Automotriz. Certain rear window glass may not have been properly tempered. If the window breaks, the glass may separate into large pieces instead of very small ones. Note: This is a voluntary recall that is not being conducted under the requirements of the Motor Vehicle Safety Act. Safety Risk: Glass that breaks in to large pieces could create a risk of injury. Corrective Actions: The company will notify consumers by mail and instruct them to inspect the designation code marked on the rear window glass. Products affected by this recall have the designation “DOT 287” along with the lettering “VMR” (Replacement Market) and a date code that is before July 2019. This information is printed on the bottom corner of the glass. Consumers should contact Vitro's customer service at 1-412-995-6457 or argbacklites@vitro.com to arrange for replacement of the glass.

On certain vehicles, the directional/hazard signals may not operate as designed. Actuation of the turn signal or hazard lights will cause them to illuminate and remain illuminated (not flash as intended). Drivers may not be able to clearly signal their intentions to turn, change travel lanes or potentially warn others of an impaired vehicle operating condition. Correction: Dealers will replace the turn signal/hazard flasher module.

Lights And Instruments 2004390 · 2004-10-29 · Transport Canada
Details

On certain vehicles, vibration and heat may cause the tail lamp/stop lamp bulb to loosen in its socket. If this occurs, the bulb may flicker and eventually become inoperative. The loss of one or both of the tail lamps/stop lamps could reduce the vehicle's visibility to following drivers and fail to warn others that the vehicle is braking and/or is stopped, which could lead to a vehicle crash. Correction: Dealers will inspect the tail lamp/stop lamp assemblies and, if necessary, replace them.

Brakes 2004088 · 2004-03-09 · Transport Canada
Details

On certain vehicles, the brake hoses are not labelled with a designation that identifies the manufacturer of the assembly as required by CMVSS 106. This non-compliance has no effect on the performance of the involved brake hose assemblies. Correction: Since this does not pose a safety risk, no corrective action is required.
