2015 Audi Q5

2015 Audi Q5 Quattro (all wheel drive). During recent inspection the vehicle was found to have extreme corrosion, cracking, and structural failure of the rear subframe and subframe crossmember. The rear steel subframe is manufactured as an assembly. The rear subframe assembly supports all of the rear suspension components and rear drivetrain and drivetrain components. My vehicle is always garaged and no other corrosion was found during inspection of the entire vehicle. The finding is a manufacturing defect that is only isolated to the rear subframe assembly of the vehicle. Due to the extreme nature of corrosion and cracking found on the subframe assembly this should be considered a high priority warning for Audi Q5 owners. A total failure of all rear suspension and drivetrain components may result.

To Whom It May Concern, I am writing to formally report a serious safety issue involving my 2015 Audi Q5 TDI (VIN # [XXX] ), which has developed severe corrosion on the rear subframe. I am the original owner of this vehicle, which has 92,700 miles and has been garage-kept and exclusively serviced by authorized Audi dealerships since purchase. On [XXX], following a failed Virginia State safety inspection, the vehicle was inspected by Audi of Chantilly, VA. Their service department confirmed that the rear subframe is cracked due to extensive rust and recommended immediate repair. I have attached both the inspection report and supporting photographs. This is not an isolated case. Numerous Audi Q5 owners have documented similar corrosion on the rear subframe, often attributed to a plastic cover that traps moisture and accelerates rusting. This appears to be a design defect with potentially dangerous implications. As it stands, the vehicle is not drivable. The compromised subframe poses a serious risk of structural failure while in motion, increasing the potential for loss of control, a crash, or injury. The dealership has estimated repairs at over $9,000, which I am currently seeking coverage for through Audi Customer Service. However, Audi has indicated that their corrosion warranty covers only body panels—not subframe components—despite the fact that the defect stems from their design.

I've reported multiple times to my dealer about the oil comsumption back in 2022 and work was performed on the vehicle in the prior year to fix leak and brake noise issue since approx 2021 on my 2015 Q5 that currently only has 65,000 miles. No warning indicator presents regarding the brakes. However oil indicator and engine light icons display. I'm constantly checking the oil indicator level to see how much is still in the and then add add once it shows thats its extremly low. I have to do this everytime I am about to use the car. This can be dangerous at times since there's no indication that its very low and its not seen unless you go into the "car" section that shows the level, it has no alert display for the level. All required diagnostic and maintenance services have been performed with the dealer. When inspecting the brake issue they always come back with no findings say that no issue could be found, howeve when I'm driving it, it sqeeks and makes a grinding sound all the time. This has been going on for quite a few years. As for the oil consumption issue, this isssue has been in recent years and both times this has been looked into by the dealer I was informed that its not covered under any manufacturers warranty and would cost me approx. $10,000.00 for them to repair it or I could trade it in. This is a very expensive luxury car and at this low milage shouldn't have these types of issue. I've seen on various car sites that both the oil comsumption and piston issue is a known issue with this model Audi and that issue occurs aournd 60,000 miles but was rectified for the models that came after 2015. I wish I had know this before making this purchase. Now the driver seat adjusting panel is broken, this came out of no where about four weeks ago with no warning. I haven't received any recall notifications since my Audi Care coverage expired, not sure why this would stop because I didn't continue this service.

The Audi Q5 was new in 2015 and I am the original owner. The vehicle has 135,600 miles on it. During an oil change visit to my repair shop, they informed me of significant rust corrosion to the subframe. My Audi dealer in Chantilly acknowledged that subframe rust was a design flaw on model years 2014, 2015, and 2016. Audi will not cover this under their 12 Year Rust Corrosion Perforation warranty. I believe this to be a significant safety hazard to the owners and their families who are still driving their Q5 without knowledge of the impending disaster. Impending disaster could be a subframe collapse at highway speed.

MY 2015 AUDI Q5 HAS 36,000 MILES ON IT, IS GARAGE KEPT AND TAKEN WELL CARE OF. IT JUST NOW HAD BOTH REAR BEARINGS GO OUT AT THE SAME TIME. IT MADE A HORRIBLE NOISE WHILE ON SMOOTH HIGHWAY, AND I HAD IT TOWED TO A MECHANIC WHO DEEMED IT UNSAFE TO DRIVE. THERE IS A RECALL ON THE FRONT BEARINGS BUT AUDI REFUSES TO TAKE RESPONSIBILITY FOR THE ISSUE. UNSAFE AND COULD KILL PEOPLE.
