2014 AUDI Q5 Complaints

I recently discovered that my Q5 tubular rear subframe/crossmember (part # 8R0505235N) has rusted thru near a bushing that supports the rear transaxle. The rust thru area at the transaxle is about a foot long. This subframe supports the rear axle and all the rear suspension components. I brought my Q5 to the local Audi dealer and they took a video showing two areas on the subframe that have rusted thru, the bushing area supporting the transaxle and also an area supporting the left rear suspension. The dealership did not allow me to take the Q5 back and gave me a loaner vehicle to drive until the subframe can be replaced. The dealership contacted Audi North America and Audi agreed to pay 40% of the cost to replace the rear subframe. I think Audi should pay 100% as this is a serious safety issue. My Q5 has no other areas of corrosion except a slight amount of surface rust on the exhaust and is otherwise in excellent condition with only 50,444 miles. It has always been garaged since purchased new and has been in no accidents. The Audi service tech even complimented me on how clean my Q5 was at 10 years old. PS - How can I include an attachment of the video taken by the Audi dealership?

Steering shaft rusted and sized. Water and mag chloride got passed the seal causing the slip joint of the steering shaft to corrode and size. The outer tube of the shaft was almost corroded through with visible holes in the metal. I believe this to be a safety concern do to the possibility of the shaft braking while driving. I am a certified Audi technician and have seen this problem on other similar vehicles. This is my personal vehicle and I have the old steering shaft for inspection if needed.

I bought my 2014 Audi Q5 in September of 2019 with 74, 291 miles from a reputable dealership in Cleveland, OH. After a few months of driving, I began to notice that the vehicle did not retain oil. This caused oil leaks which led to internal spillage, subsequent parts damage and random stalling. As a result, in May of 2022, during rush hour traffic, my car failed to accelerate mid-intersection, leaving myself and my passengers in danger of collision. After dealership and independent inspection, it was determined there was an issue with the piston rings in the 2.0 Turbo engine. After speaking with the mechanic, Audi USA and conducting online research, I found that this has been noted and reported to Audi on several occasions for makes and models dating as far back as 2012. Because this is major engine issue, I fear for what other repercussions may result from the negligence. Upon further research, I also found that several class action lawsuits have been filed country-wide due to concern of this factory malfunction. These vehicles are large and capable of irreparable damage. Whatever steps can be taken to avoid sudden engine failure similar to my own is of highest priority.

Engine oil consumption between every 200miles and 300miles spends a quarter of complete engine oil

I am reporting Audi Side Assist System fault. Audi assist among other things provides blind spot warning and is major safety feature in the car. Basically when I am switching lanes on, I get existance of car in blind spot. When driving in January I received warning message that said Audi Side Assist System fault. I scheduled service for Feb 3 and the car was repaired by Feb 4. Originally they suspected accident or repair work done around the back bumper. Later they realized that none was done and fixed the issue by "alignment". During that work they found out that the two assist modules have different versions which is surprising since all my service was done at Audi San Jose dealership and never repaired that function. This means that my car original parts has version mismatch. The function worked OK for several weeks but failed again on April 1. I still did not repair it but I am scheduled on May 10 (earliest date). The fault is still on!

Timing chain, turbocharger and high pressure fuel pump has to be replaced for the car with 75000 miles on it. Was advised by the shop supervisor that it’s caused by faulty engine. That this type of damage is highly unlikely for the car under 100000 miles. Turbocharger is under extended warranty from the previous Audi recall.

Check engine light on and diagnostic test shows particular matter sensor malfunction. This is apparently under recall, but my VIN is not included

I have a 2014 Audi Q5 Premium Plus with 3.0 liter engine. I was in Wolfeboro NH this past weekend and it was very cold, -15 at night. My vehicle has 123000 miles on it and has run with no issues to this point. Luckily , I parked the car to go into store and when I came out DSC red warning light came on , could not budge the steering wheel. Looked up issue in manual and said do not drive. I am from CT so no car now in NH. I had vehicle towed to closest Audi dealer , 60 miles away for service. It turns out to be I need a whole new steering column due to cold temperatures. If this happened while driving it would have been devastating. My issue is there was a recall on the 2014 SQ5 for the exact same issue. I have found numerous complaints for the same issue for the same vehicle, why has there not been recall? This could have ben a deadly incident in the wrong situation. Vehicle at Audi dealer to the tune of $3600 for repairs.

Seatbelt tensioner and air bags failed to deploy when the vehicles was in a severe frontal collision when another vehicle ran a stop sign exiting the highway.

My 2014 Audi Q5 2.0L Turbo, at 84339 miles, is consuming oil between oil changes. 4300 miles after my last oil change by the Audi dealership, I had to add oil. The dealership, Gwinnett Audi, 3190 Satellite Blvd, Duluth, GA 30090, said that Audi is paying for the oil top off for all customers. Seems odd that if this is normal that Audi would voluntarily reimburse the dealership for this expense. I am concerned, based on internet searches, that this will continue to get worse and I will be adding more and more oil without getting the problem resolved. The dealership told me it would cost $7,000 to fix the engine and there is no longer a warranty. This vehicle should not be burning oil at $80,000 miles. Audi needs to make permanent repairs to fix the problem, not just put a bandaid on it. I am not the only Audi owner with this problem.
