2015 AUDI Q5 Complaints

Audi Dealer inspection report said severe rear sub frame rust is a safety issue and requires replacement

The contact owns a 2015 Audi Q5. The contact stated when the vehicle was driven to the independent mechanic for an inspection for a possible oil leak, the mechanic observed that there was a significant amount of corrosion on the rear sub frame of the vehicle. The contact was advised by the mechanic that the vehicle was unsafe to drive due to the extreme corrosion of the rear sub frame. The vehicle was not taken to a dealer to be diagnosed or repaired. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 110,000.

Cylinder #3 lost compression, down to 30 psi from 170 psi, causing the car to lose power and run extremely rough or not run on occasion. This is a safety hazard, especially risky for highway driving. There were no warning messages, car just start running very rough or wouldn't start. Such loss of compression has been reported by an Audi service manager who says Cylinder #3 is known to have this issue, but there is no recall for it yet. The problems began in May 2021. The car was drinking/consuming oil frequently and occasionally running rough. It was taken to multiple mechanics to identify the issue. Fixes included changing spark plugs, coils, and the PCV valve to provide temporary solutions at best. 5/24/21 increased consumption of oil began 9/9/22 rough idle, spark plugs replaced 10/14/22 rough idle and burning oil, taken to a service shop, replaced the PCV valve 7/12/23 rough idle again, spark plugs replaced again under warranty 2/14/24 - rough shake again, spark plugs replaced again and dead cylinder #3 confirmed

Sub frame is rusted out. Major safety issue. Confirmed by 3 independent auto repair shops. Removing and replacing the rear sub frames. $ 1800.00

I was driving down the road when the steering stop working and I could not control the direction that the tires moved. The direction of steering would not respond to my movements and I was unable to control the car. I was able to break and bring the car to a stop, however, if I were moving at a much faster speed this would have been extremely dangerous. I brought the car to our mechanic and we were informed that the tie rods were broken, the threading on the attachment pieces was completely rusted out and the threads were bare. The piece simply came apart and was malfunctioning. No warning signs or service lights came on in the vehicle before this happened and we had no indication that there would be an issue with the steering when operating the vehicle. Our mechanic told us this was one of the most dangerous things he's ever seen happen in a car and that our life was at risk. We regularly have our car inspected and serviced and there was no indication that this would happen. Our car had a major engine problem in August 2023 and was at the Valenti Audi Dealership in Waterbury, CT, during that time the car was inspected and we were not told the tie-rods had any problems.

We have never had an issue with the vehicle until we recently faced very cold Temps (-10 to -20). Was driving the vehicle, with no issues, and stopped to get gas. Upon restarting the vehicle it displayed a power steering error with a do not drive. The steerling lost all power steering function and was extremely hard to turn. We let the vehicle sit and restarted it 3-4 times and on the fourth try, the error went away and there was no further issues with the power steering on this (first) occasion. This has now happened intermittently since the first occurrence (even with very cold Temps) but with no regularity. Not sure if this is a malfunction or if there is something in need of replacement. It is extremely concerning.

in 2017 Audi repaired a leaky fuel pump in my Q5 due to a recall. My vehicle now has less than 35k miles since that repair and the new-replacement fuel pump flange is failing again. Fuel was coming out and created a significant fire risk to life and property. Audi has refused to deal with the issue and speaking with mechanics at 3 dealerships revealed that the replacement parts are failing at an alarming rate. I would like this looked into.

Complete hydraulic brake failure while on an interstate going 75mph. No warning, just sudden loss of regular and emergency brakes. I was able to cross 4 lanes of traffic to get to the shoulder where I waited absolutely terrified of being rear-ended for the two hours it took for a tow truck to arrive. My repair place was shocked at the problem, considering the car was 8 years old with low mileage. They found the only after-market part in the entire country and repaired it for under $2000 when they initially thought it would be $6000.

The contact owns a 2015 Audi Q5. The contact stated that the vehicle was consuming an excessive amount of engine oil. The vehicle was taken to a dealer where it was discovered that oil had leaked into the engine coolant. Due to the failure, the oil cooler was replaced; however, the failure persisted. The vehicle was taken back to the dealer where an oil consumption test was performed. The test showed that the piston rings were defective and needed to be replaced. The manufacturer was notified of the failure and informed the contact that there were no recalls on the VIN. The vehicle was not repaired. The failure mileage was approximately 75,000.

The car presently has about 92,000 miles on it. Around 80,000 miles (back over the winter) the oil light started to come on indicating I'm down a quart or so. I would find myself putting in a quart of oil every 1,000 miles or so. It has progressed. I understand the vehicle has a problem with the piston ring design such that the ring allows excess oil into the chamber and the ring itself might shatter. The problem, at best, prevents acceleration and deceleration...problematic on or off a highway. At worst, the ring shatters and engine stops. The 2012 - 2017 models and other models were involved in class action lawsuits. The 2015 escaped that litigation somehow. Though I'll be taking it to an Audi dealer for an oil consumption test as recommended. No one has yet to inspect the vehicle.
