2009 Audi Q5

I am reporting a potentially serious safety defect involving the rear subframe/crossmember of my 2009 Audi Q5. I discovered significant corrosion on the vehicle's rear subframe, which is a structural component supporting the rear suspension and rear axle assembly. The corrosion is substantially more than normal superficial surface rust. There is visible rust scaling and loss of material in areas of the rear subframe. The affected area was partially concealed by the factory-installed plastic stone guards/shields. Because these plastic covers obscure the subframe, the extent of the corrosion is difficult to identify during a normal visual inspection unless the covers are removed. I am concerned that continued corrosion could reduce the structural integrity of the rear subframe and potentially compromise the mounting points for the rear suspension or rear axle components. A structural failure of the rear subframe could result in unexpected changes in wheel alignment, suspension movement, loss of vehicle control, or other serious safety consequences. This issue is particularly concerning because the corrosion can develop underneath the plastic protective covers and may not be visible to the vehicle owner during normal operation. Safety Concern The rear subframe is not merely a cosmetic body panel. It is a structural component associated with the rear suspension and axle assembly. If corrosion continues to remove structural material, a suspension mounting point or section of the subframe could potentially weaken or fail under normal driving loads. A failure while the vehicle is being driven, particularly at highway speed, could potentially result in loss of vehicle control. There were no dashboard warning lights or electronic warnings indicating this condition. The problem was discovered through physical inspection of the underside of the vehicle. Possible Design/Corrosion Mechanism The factory-installed plastic stone guards appear to cover portions of the rea

Cybex Sirona S is marketed as a 360 car seat that rotates and swivels, but when in forward-facing mode for functionality it does not tether. The guidance is to use the load leg to keep the swivel and rotation but then not use the tether. The tether strap is critical for safety and part of CPST guidance. People purchasing this seat are being made to compromise safety for functionality.

The contact owns a 2009 Audi Q5. The contact stated that the vehicle was smoking. There was antifreeze and oil leaking from the vehicle. While driving, the accelerator pedal and brake pedal became stuck, and the vehicle stalled. There was an abnormal oil burning odor, fuel, and antifreeze. The vehicle was also consuming an excessive amount of fuel. The gear shifter button was also stuck. The gear box malfunctioned, and a message to restart vehicle was displayed. Additionally, the tailgate seized while going up and down. The vehicle was taken to an independent mechanic where additional oil was added several days. The vehicle was taken to an unknown local dealer where the antifreeze was changed. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was approximately 140,000.

ON 7/02/09 MY AUDI Q5 (VIN# [XXX]) WAS PURCHASED FROM, AND SERVICED BY BARRIER AUDI BELLEVUE, WASHINGTON; NOW DOING BUSINESS AS AUDI BELLEVUE A DEALERSHIP OWNED AND OPERATED BY AUTO NATION. TECHNICAL SERVICE BULLETINS [TSB] WERE SENT TO SOME AUDI OWNERS ON 12/6/2013 CONCERNING REPAIR AND CLEANING OF THE SECONDARY AIR CONTROL VALVE WITH A WARRANTY EXTENDING THROUGH 07/02/2019. THIS PROBLEM WAS INITIALLY CORRECTED ON 12/27/2013 @44,445 MILES, MY LAST SERVICE WITH BARRIER WAS 09/13/2018 AND AT NO TIME HAD I RECEIVED NOTICE THAT THE PROBLEM COULD RESURFACE. THE TSB PROVIDES : "THE SECONDARY AIR SYSTEM ON THESE VEHICLES IS USED TO HEAT UP THE CATALYTIC CONVERTERS QUICKLY DURING COLD-START CONDITIONS?. OVER TIME, AND DEPENDING ON DRIVING STYLES, CARBON WILL BUILD UP IN THESE SMALL 10MM PORTS AND CAUSE FAULTS IN THE ENGINE CONTROL MODULE FOR SECONDARY AIR, BANK1/BANK2 INSUFFICIENT FLOW? SOME MODELS DO HAVE A WARRANTY EXTENSION, WHICH COVERS THE SECONDARY AIR PORT CLEANING UP TO 10 YEAR/110,000 MILES. PLEASE CHECK WITH YOUR LOCAL DEALER FOR DETAILS. KEEP IN MIND, IF ANY OF THE CONTROL VALVES, COMBI VALVES, OR SUPPLY LINES ARE DAMAGED, OR FAULTY, THOSE ITEMS ARE NOT COVERED UNDER THE WARRANTY EXTENSION, AND WOULD HAVE TO BE REPLACED BEFORE THE PORT CLEANING CAN BE PERFORMED." ON 10/01/ 2019, AN ENGINE WARNING LIGHT WAS DETECTED ON THE Q5 WITH APPROXIMATELY 106,000 MILES ON THE ODOMETER. ON 10/28/2019 A CLAIM [#190822437]` WAS FILED WITH AUDI USA AND DENIED AS UNTIMELY FILED. AUDI BELLEVUE CARRIED OUT REPAIRS AT MY EXPENSE FOR $ 2045.75. GIVEN THE FACT THAT THERE WAS NO NOTICE, THE CONTINUED WARRANTY PERIOD SHOULD BE EXTENDED BY AUDI USA AND THE COSTS OF REPAIR REIMBURSED.
