When owners complained

A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

Recalls on the 2009 Porsche Cayenne

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2022487 58,856 units in Canada

Lights And Instruments

Issue: On certain vehicles, covers were not installed over the horizontal headlamp adjusters. As a result, the headlamps may be adjusted horizontally. Canadian regulations do not allow for horizontal headlamp adjustment unless the vehicle is equipped with a built-in aiming device. Safety Risk: Headlamps that are not properly adjusted could cause reduced visibility or glare for oncoming drivers, and increase the risk of a crash. Corrective Actions: Porsche will notify owners by mail and instruct you to take your vehicle to a dealership to install caps over the headlamp adjustment screws.

Recall 2019290 8,742 units in Canada

Powertrain

Issue: On certain vehicles, the transmission shifter could detach from the transmission. This could cause the transmission not to shift gears when the shifter is moved. As a result, the transmission could be in a different gear than the gear shifter indicates. If a driver attempts to exit the vehicle while the transmission is not in Park, and the parking brake is not applied, the vehicle could move suddenly. Safety Risk: Sudden and unexpected movement of the vehicle could increase the risk of a crash. Corrective Actions: Porsche will notify owners by mail and instruct them to take their vehicle to a dealer to replace the shifter cable bushing. Owners are reminded to use the parking brake anytime the vehicle is parked.

Recall 2019192 33,832 units in Canada

Label

Issue: Certain wheels were made without a marking that is required by Canadian regulations. Safety Risk: This small error does not affect safety. Corrective Actions: This is not a recall. The company has made changes to include the required marking on all new parts.

Recalls cover specific build ranges, so check your own vehicle by VIN at nhtsa.gov/recalls or, in Canada, Transport Canada.

EQUIPMENT

UNABLE TO LISTEN TO RADIO STATIONS ON RADIO DUE TO STATIC NOISE AND HEAVY SOUND INTERFERENCES EVEN ON LOCAL NJ FM RADIO STATIONS. THIS DEFECT SUBSTANTIALLY IMPAIRS THE USE, VALUE OR SAFETY OF THE VEHICLE, AS THIS IS CAUSING DRIVER FRUSTRATION AND REDUCED DRIVER FOCUS WHICH I AM AFRAID WILL LEAD TO A POTENTIAL ACCIDENT DUE TO NOT BEING ABLE TO LISTEN OR LISTEN WITH STATIC AND HEAVY SOUND INTERFERENCES TO THE RADIO FOR NEWS, MUSIC AND RADIO TALK. THIS HAS BEEN CONFIRMED AND TESTED BY AN INDEPENDENT AUDIO PROFESSIONAL IN WRITING AND REPORT CONCLUSION IS "RADIO STATIONS NOT WORKING CORRECTLY, HEAVY INTERFERENCES. TESTED ON LOCAL NJ STATIONS 94.3FM AND 101.5FM",
