2009 Acura RDX Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

What this page shows

Everything below is an owner-reported complaint submitted to NHTSA about the 2009 Acura RDX, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.

Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

report

From owner reports, verbatim

A DRIVER AND ONE PASSENGER WERE TRAVELING DOWN AN INTERSTATE HIGHWAY AT APPROX. 70 MPH. ALL WINDOWS WERE CLOSED, THE SUNROOF AND SUNROOF SHADE WERE CLOSED. APPROX. OUTSIDE TEMPERATURE WAS 45 DEGREES FAHRENHEIT, A SUNNY BUT COLD DAY, AND THE INSIDE VEHICLE TEMPERATURE WAS APPROX. 70 DEGREES FAHRENHEIT. OUT OF NOWHERE, A LOUD POP (LIKE A GUNSHOT) WAS HEARD. IMMEDIATELY FOLLOWING, THERE WAS THE FAINT SOUND OF OUTSIDE AIR COMING FROM THE SUNROOF. THE DRIVER OPENED THE SUNROOF SHADE JUST ENOUGH TO IMMEDIATELY SEE THAT THE ENTIRE SUNROOF GLASS WAS SHATTERED (STILL INTACT, BUT COMPLETELY SHATTERED). WITHIN THREE MINUTES WHEN A SAFE PLACE WAS REACHED, THE VEHICLE WAS PULLED OVER TO EXAMINE FROM OUTSIDE. DRIVER GOT OUT OF THE CAR, AND SAW THAT THE GLASS SUNROOF WAS BUCKLED UPWARDS (AS THOUGH IT HAD POPPED FROM THE INSIDE). THE GLASS WAS NOT BROKEN IN ANY PATTERN WHICH INDICATED AN OBJECT FROM OUTSIDE THE VEHICLE HAD HIT IT. THERE WAS NO EVIDENCE ANYWHERE ELSE ON THE ROOF OF THE VEHICLE OF ANY INCIDENT. IT WAS CLEAR THAT THE GLASS HAD POPPED, POTENTIALLY DUE TO INCORRECT PRESSURE INSIDE THE VEHICLE, FROM THE INSIDE OUT. THESE FACTORS LEAD US TO BELIEVE THE INCIDENT IS A VEHICLE SAFETY ISSUE, AT THE FAULT OF THE MANUFACTURER. *TR
