2014 Audi Q5: engine failure

Filed Mar 21, 2026 · Engine · CA

I am filing a safety complaint regarding a progressive engine defect. Beginning as early as 2019 (approximately 84,000 miles), I repeatedly reported excessive oil consumption and related engine concerns to authorized Audi dealerships. These complaints continued over several years. At no point was I informed that these symptoms could be associated with a known defect pattern or progressive engine failure. The condition has now escalated to a severe engine malfunction. The vehicle began exhibiting engine misfires, flashing check engine light, EPC warning, and unstable operation. The dealership confirmed misfire fault codes and oil contamination affecting the ignition system. Engine replacement was initially recommended. Excessive oil consumption leading to internal contamination and misfires presents a significant safety hazard. Loss of engine power or sudden failure while driving can create dangerous conditions, particularly at highway speeds or in traffic. Despite the long history of reported symptoms, Audi of America has declined to provide assistance, citing only warranty status and failing to address the defect progression. The vehicle has now been inoperable at an Audi dealership for approximately 60 days (nearly two months), with no resolution. This situation raises concerns regarding a safety-related defect, failure to disclose a known issue, and a potential broader pattern affecting similar vehicles equipped with this engine. I am requesting that this issue be reviewed for potential defect investigation. The dealer provided diagnostic findings with Failure Codes via a temporary link that is no longer accessible. I am requesting a copy of the full report and will upload this (once received), along with other documentation.

The car has a known "oil consumption issue" that has led to engine failure that Audi has failed to take responsibility for. This is a 2104 Audi Q5. The car is in San Francisco and available for inspection. The car vibrates and can't be safely driven at highway speeds, if the engine suddenly lost power on the highway it could be a major safety issue for the driver and other drivers. The dealer has reproduced the issue and diagnosed it as needing new Pistons and Rings at 99,000 miles (but it has had this issue since in the 60,000 mile range, they just said keep adding oil). It has not been inspected by police or insurance representatives, just the dealers. I'm sure some warning lights came on, but could not say which ones or when.

In 2017 while driving in 10 degree weather, the overheat warning light and message to turn off engine came in. The car was not actually overheating and we took it straight to the dealership. They were not able to get it to replicate and advised it was possibly a faulty sensor. Fast forward to fall of 2023, the same warning light came on as soon as the car was turned on. Still no actual overheating per the dial in the car. We did check the coolant level and it was low. Dealership looked at and stated the didn't see any leaks and suggested replacing thermostat. Took to another shop and they found a small leak in the water pump so we had it replaced. Car has less than 60k miles on it. Engine failure, fire are all concerns. Especially when commuting at high speeds on a highway. We're either dealing with a faulty water pump or thermostat.

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.

While driving the car, car suddenly stopped... A lot of lights came on in the dashboard. There was a burning smell inside the car. Car wouldn't start after that and had to be manually pushed to the side of the road. Audi service inspected the car and said that engine had internal damage and I was asked to replace the engine. Car only had 35,000 miles on it. Warranty had expired just few months earlier. I had gotten service done every year at the same audi service dealership and had gotten a service just a few weeks before this happened! I was asked to replace the engine at my cost!! Later I was offered assistance from audi, but it still cost me $4,500 out of my pocket for a 4 yr old car with 35k miles on it and serviced every year by audi!! Lost faith in the audi brand and the local audi dealership & service.
