2022-2023 Volkswagen Tiguan Oil Consumption Problem

Class Action Investigation

Updated on October 1st, 2024 Author: Sergei Lemberg

Lemberg Law is investigating ongoing consumer complaints about oil leaks and excessive oil usage by the 2022 and 2023 Volkswagen Tiguan models. As if that’s not bad enough, many owners are complaining that they get no help or support from the automaker or VW dealerships. Worse still, some dealers maintain that the oil consumption described is normal.

Introduction to VW Tiguan Oil Issues

Complaints to the National Highway Traffic Safety Administration (NHTSA) and discussions on multiple Reddit threads indicate that Tiguan oil consumption is a major problem. Of course, not all owners have experienced the problem. However, many have, and there is little doubt that many more will do so in the future. Most complaints show that it isn’t usually a problem with new vehicles. Rather, oil problems seem to develop over time, and those who are affected are hugely frustrated.

This comment was made in response to recent posts on Reddit about excessive oil consumption: “I am having the same issue with my 2023 Tiguan. And honestly, it is really frustrating. Haven’t had the issue for the first 20k miles. It started afterward.”

What Are Owners Experiencing

There are more complaints to the NHTSA about the 2022 VW Tiguan than the 2023 model, but the issues are the same. The overall message is that both MY Tiguans use excessive oil. Typical oil consumption problems reported by consumers include:

• Low oil warning lights
• Oil leaks
• Blue-tinted smoke when starting or warming up
• Oil so low the dipstick had no oil on it
• A need to top up oil frequently

What Volkswagen Has Said

The short answer to this question is not very much! We have viewed hundreds of manufacturer communications, which must be filed with the NHTSA by law.

There are multiple technical service bulletins (TSBs) that advise and update dealerships about engine oil quality standards. There are also several that talk about oil pressure priming.

A TSB released on June 20, 2023, attempts to explain a customer complaint that “oil consumption is higher than the Volkswagen oil consumption standard of up to 0.5 quarts per 600 miles, or 0.5 liters per 1000 km.” This document relates to all 2000-2024 VW models except the Routan minivan. It states that “Typically, engines with specified break-in periods consume more oil during the break-in period, and the oil consumption will stabilize after the break-in period.” Additionally, it states that “the rate of oil consumption depends on the quality and viscosity of the oil, the RPM at which the engine is operated, the ambient temperature, and road conditions. Further factors include the amount of oil dilution from water condensation or fuel residue and the oxidation level of the oil.”

VW’s advice to dealerships is to explain the technical background to customers before testing or attempting any form of repair! Then, they should test for leaks and possibly perform an oil consumption test, details of which are provided.

Additionally, there is another TSB released on June 26, 2023, that tells dealerships how to test oil levels during a pre-delivery inspection (PDI). This relates to all gasoline models except the Routan), manufactured between 2014-2024. It is not a bulletin that aims to solve problems.

Complaints

Only one complaint to the NHTSA highlights a dealership that acknowledges there is “an issue with VW Tiguan engines burning oil at a higher rate than the standard.” An owner from Vermont states in a May 2024 complaint that this dealership was in West Lebanon, New Hampshire. The complaint states that the fuel low indicator kept coming on. At first, the dealership’s advice was to add oil. Then they agreed to do a fuel consumption test. “They stated they are seeing a lot more folks like myself coming in with lower mile Tiguan with this issue. Normally they are seeing many with 50K + miles.  While I was there another customer overheard the service adviser talking to me and he said he had the same issue.”

The complaint also reports “blue puffs of smoke coming out of the back” when they start the Tiguan. “It seems like this is a huge issue that is now coming to light. The dealership told me I’m at stage 2 with VW and (the) next step is taking (the) engine apart and warning VW of (the) issue.”

Some dealerships acknowledge there is a problem, but they identify different issues. Others maintain that vehicles are functioning normally or they cannot find a problem.

Dealerships Diagnose Different Issues

A New York owner of a 2022 Tiguan noticed “excessive smoke coming from the exhaust pipes” while driving and the low oil warning light was illuminated. The vehicle, which had 1,000 miles on the clock, was taken to the dealer who diagnosed a failure with the valve steam seals. These are critical components that help to control the amount of oil that enters the engine’s combustion chamber through the valve guides. Symptoms include blue smoke from the exhaust and increased oil consumption.

“The vehicle was repaired, but the failure reoccurred. It was taken back to the dealer, who then diagnosed a failure with the fuel vapor leak detection pump. The vehicle was repaired, but the failure reoccurred. The manufacturer was notified of the failure but provided no assistance.”

Another Vermont owner states that the low oil light came on soon after an oil change when the mileage was less than 2,000. This dealership also said seals (two) needed to be replaced. This was done and the owner was advised to check the oil “every so often.” After driving a further 500 miles, the vehicle needed at least 1 quart of oil. I “took it back to (the) dealership (and) now they say I need a whole new Head and it is a common problem. They have done about 3-4 in 2024! I feel like that’s a safety concern but they don’t.”

Dealers Say High Oil Consumption Is Normal

An owner from Michigan states that a 2022 Tiguan was using excess oil since it had done about 15,000 miles. It also blows blue smoke at start-up at times. “Engine now has 35,000 miles and uses all of its engine oil before its next scheduled maintenance.” An oil consumption test revealed it uses .61 quarts per 1000 miles. But VW maintains this is normal. “VW states to change oil every 10,000 miles. It will be gone and (the) engine will have no oil remaining within the scheduled maintenance (period).” This owner has contacted VW directly and maintains the vehicle will have cost over $1000 per mile to own. However, the “dealer and VW keep telling us to just check oil. It’s normal… This is NOT normal.”

The Nevada owner of a 2023 Tigua states that it consumes a lot of engine oil. “Every 2,000 and 3,000 miles, the oil engine light turns on and it shows that oil level is low.” The second time it happened he took the vehicle in and was told it was normal to have to have to add oil every 3,000 miles.

An owner from Connecticut complained that the oil light went out in May 2023 (at 15,000 miles) and August 2023 (17,500 miles). Both times the oil was down to 1 quart and smoke had been coming out of the exhaust intermittently. The “VW service department did an oil consumption test which resulted in the car burning just under a quart of oil after 600 miles.  They said the car is functioning normally, but if it burned over a 1/2 quart of oil, they would do something.”

Online Discussion

The conversation on several Reddit threads tells the same story. Tiguans get low on oil in between oil changes. Drivers notice blueish smoke. Dealers say it’s normal!

“I have a 2023 Tiguan and it’s burning oil. The first time (the) dealership said it was normal to have to add oil. Then because it was low again and smoking more frequently they decided it was time to check it. Now, they think it’s a valve guide issue and that part is on back order so they had to give me a loaner as they have no idea when I’ll be able to get my car back.”

Another 2023 Tiguan owner states,  I’m at about 7,500 miles on my 23 and just got the low oil light. Checked the dipstick and sure enough I’m right below the hashes. I added a half quart to get me to my service in a month but I’m wondering if I should be asking about this.”

The response was: “I would report it to the dealership the next time it happens. My dealership topped off the oil and I had them track how much oil was being consumed. In my case, it was 1.5 quarts. every 500-600 miles (spec is .5 quarts every 600 miles.) Oil consumption tests came back “Within Limits” but I sat down with them and did the Math. They reached out to technicians at VW of America and found oil leading to the pipe that leads to the intake manifold. Changed the PCV valve but no change in consumption. Check Engine light came on just prior to the oil light coming on again. Error Code P0491. Head gasket and valve seal guides changed. Waiting to see if (the) problem is finally resolved.”

More Examples of Dealerships Stating High Oil Consumption Is Normal

“I got my 2023 Tiguan, new, in October of 2022. To sum it up, I’ve had issues with the car notifying me that my oil is low consistently every 2,500-3,000 miles. I have taken it into the dealer probably 6-7 times to get the oil topped off, and they continue to say this is a normal thing with these newer engines that they consume a lot of oil. But every 2,500-3,000 miles? This is something I wasn’t told before I bought the car in any capacity.”

“I was looking at a 2022 Tiguan SEL R-Line online and once I looked at the Carfax I found out it had been a manufacturer buyback car after many many oil changes, oil consumption tests performed, heads changed, etc… and then had been auctioned to the selling used car dealer. I have since found that many 2022s have this issue and that dealers like to say it’s normal for the engine to consume x amount of oil. Of course, that’s an outright lie. My 2019 didn’t consume any oil. Unfortunately, someone hit me and totaled it.”
