2014 Audi Q5

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.

Under Recall 19N4, the electric coolant pump was replaced in July 2019 at 73,496 miles. That replacement pump failed prematurely in March 2025 at 109,628 miles — lasting only 36,132 miles. This was a safety-related recall part intended to fix a known defect with the original pump. Audi refused to provide goodwill reimbursement for this premature failure. I am reporting this to request further investigation and possible expanded remedy.

I have noticed 2 times that my engine burn out oil very quick before the next predicted oil change and lead to safety risk of boosting engine while driving long distance if there is no auto one near. After speaking with one of the maintenance guy the last time I went for oil change at Jiffy live, He told me that there was a recall for the same problem with some other Audi models. How could we expect your help to address this safety concern with the manufacturer. This is very dangerous situation that you can’t neglect. Best regards,

The contact owns a 2014 Audi Q5. The contact stated that while driving 60 MPH, the vehicle briefly lost motive power and the vehicle stalled. The contact was able to coast to the side of the road. No warning light was illuminated. The vehicle was towed to the daughter's residence. The contact stated that weeks before the failure, while the vehicle was being serviced at the dealer, it was determined that the engine was consuming an excessive amount of engine oil. The vehicle was not repaired. The manufacturer was made aware of the first failure. The failure mileage was 72,919.

Vehicle stopped while driving!!! Middle of the driving. Very dangerous. And it happened twice. With that as the headline, another known problem with this vehicle has been the engine oil needing to be filled literally every month. And time to time it resulted in “engine light” to come. So we kind of ended up in a “wolf cry” and really didn’t act. However, we did take care to Audi service for oil refill and they IGNORED to do the inspection on engine light well under 100,000 miles and 10yrs on warranty. So our recent car stopped when we were just about 2 months over 10yrs and 3,000 miles over 100,000 mile warranty Audi has for the problem needs repaired. Please help. Now Audi is saying we needed to pay almost $6,000 to get that repaired. Which they have seen for months prior to the 10yrs and 100,000. It’s really a unfair business practice.

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.
