2018 Volkswagen Atlas Engine Problems

The water pump failed catastrophically at 63,100 miles, forcing a complete road-side breakdown and damaging the radiator. This is a known manufacturing defect affecting the 3.6L VR6 composite plastic pumps. Due to the failure of the pump, the radiator tank became hot causing a hole to form in the radiator and needing to be replaced. I still own this car and you may inspect it if needed. My safety was at risk as well as others safely was put at risk because this caused car to over heat leaving me broken down on the side of the road. My mechanic at specialized auto repair confirmed and reported this issue to me and they provided the repair. It was not inspected by police, or insurance because it was a break down, not an accident and that's not coved by insurance. I knew that the car was overheating because waring system showed it to be overheating. It was actually more than over heating because of the water pump failure, the radiator melted causing car to dump all the coolant/water creating an over heating emergency. The warning system first appeared at the same time as the pump failure and the car had already overheated due to radiator hole when the waring system alerted me to the car overheating.

The contact owns a 2018 Volkswagen Atlas. The contact stated that while driving on several occasions at various speeds, "low coolant" and "overheating" messages and the check engine warning light illuminated. On the first two occasions, the low coolant message appeared. The vehicle was pulled to the side of the road and inspected, and she observed a leak under the engine compartment. The vehicle was taken to the same dealer twice, where it was diagnosed that the water pump needed to be replaced. The vehicle was repaired twice, but the failure reoccurred approximately two years later. The contact stated that on the third occasion, an "overheating, turn engine off immediately" message appeared and an alert warning chime went off. The vehicle was pulled over to the side of the road and turned off to cool down. The contact stated that when the vehicle was turned on, it began to overheat again. The vehicle was then towed to the same dealer, where it was diagnosed that the water pump and a possible additional unknown failure were the cause. The vehicle was repaired, but the failure persisted. The dealer advised the contact that they may need to replace the head gasket as well. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 40,000.

Vehicle has heavy leak from water pump. Most vehicles of this model have extended warentee due to class action lawsuit from failing water pump, primarily the 4cylinder models, but it is a well known issue among the V6 models, and some of those are covered as well. Vehicle has 56K miles at this time.

Multiple low coolant alerts. Dealer inspected 3 times and denied problem while vehicle still under warranty. Dealer simply topped off coolant and denied finding leaks or any other issue. Now low coolant again and EPC/ check engine light. Took car to independent owned shop who confirmed 2 water pump failures. Dealer refusing accountability for missing water pump issues that led to possible overheating damage. Big bill but dealer says my vehicle is not part of the ongoing water pump issues with other 2018 Atlas. My vehicle is being repaired by independent shop at my expense. Available for inspection if needed to further this complaint. Help is appreciated and desperately needed. Thanks.

My 2018 Volkswagen Atlas V6 experienced a catastrophic engine failure at approximately 116,000 miles. The vehicle has been at a Volkswagen dealership for approximately six months (since July 2025) while repeated diagnostic attempts and repairs were made. I was ultimately informed that the engine requires full replacement. No clear warning was provided prior to failure, and the prolonged diagnosis resulted in the vehicle being unusable for an unreasonable length of time. Volkswagen of America has declined to offer assistance despite the severity of the failure and extended time out of service. I have reached out to Volkswagon and so has the dealership (Paul Miller Volkswagen of Bernardsville). We each created a case each on my behalf but Volkswagon of America has declined assistance. I am concerned about premature engine failure and the lack of resolution.

While driving, the vehicle suddenly loses engine power and shuts off without warning. This has happened multiple times and creates a serious safety hazard because it happen in traffic multiple times . The problem appears to be related to the fuel pump control module and/or electrical wiring failure. Additionally, the power windows stopped functioning due to a failure in the driver door wiring harness, which is a known issue on this vehicle model year. The electrical malfunction and engine stall appear to be connected. This issue has been repaired because the dealership stated the warranty is expired, but this is a safety defect that can lead to a crash. There is also an open unrepaired recall on this vehicle. The vehicle is available for inspection.

Low engine coolant light came on and began overheating all within a short period of time. Mechanic stated is has a blown/defective head gasket. It is currently being repaired by a mechanic as we need the car to drive our young children. A quick Google search has shown this is an ongoing issue as there is a class action lawsuit with law group, Sauder Schelkopf.

Our 2018 VW, when extremely hot temperatures would make a very loud grinding/squealing sound. Then the AC would intermittently work, sometimes it would blow cold, and sometimes it would not. Eventually, the AC stopped working altogether. There is a strong, hot, burning smell that comes through the vents during these times. These issues have caused extreme visibility as my windows fog up in humid conditions, causing me to not be able to see. I was almost in a car accident from this due to not being able to see and being in a large amount of traffic, trying to pull over to the side. This happened probably because the AC also dehumidifies the air for defogging. We had our VW into the Morris dealership, being sent home each time, stating nothing was wrong. The last time we had it in demanding something was not right. They stated the AC Compressor is not engaging now. Well, this explains why, every time it is hot and humid or raining, my windows are fogging up, causing me to not be able to see anything. This is an extreme safety hazard and has been for me and my children. This also explains the musty smell because this can cause mold and bacteria to grow due to trapped moisture. This is hard when this is our only family car, and many safety hazards.

I have had this vehicle since 2020. Two months after I bought it, the vehicle would turn off at random. I took it to VW and they change the carbon air canister. It stopped for a while but now it back. When stopping the car randomly shits off. Not auto energy saving off. Restart your engine in 5:30PM traffic type of restart your engine. Slowing down, shut off. Backing up, shut off. I have a 2019 Atlas as well and the same thing happens. This is extremely dangerous and unsafe. VW claims either they dont know what the issue is because there is no service engine light and no code produced.

In October 2024, my air conditioning was blowing hot when I had just had it recharged in June 2024. I took it to vw in pasadena, ca. They noted that there was an oil leak being caused by the breather valve aka the pcv valve which was making oil leak into the ac components. It took a few visits to get this resolved as a smell was in my car that was making me feel sick afterward. Eventually it was fixed and my car seemed to be okay. Until a month ago when my husband got into an accident and once we got my car back from the body repairs within 24 hours, my oil light came on. At first I thought it was because of the accident but it turned out it wasn't. It was due to the breather valve again. This was confirmed by vw covina. This is unsafe because it can cause oil to leak into other components of the vehicle and cause them to fail. Your head gasket and oil pan can also be affected and maybe more, I'm not sure what else as I am not a mechanic. But I know this is an issue with many atlases from a simple Google search, there are thousands of people experiencing the same. I do not have the documentation for the current repair as they are working on my car right now so I dont have the paperwork yet. If you all contact me in a few days, I'm sure I should have it by then and would be happy to provide it.

I was driving on the highway with my family in stop and go traffic when my car turned off on its own while still in Drive. The car has an "Auto On/Off" feature that we had disabled so it should not have, for any reason, done this. We had a semi-truck behind us that nearly rearended us. After putting the car in park, in the middle of the highway, and restarting the engine the car turned off again less than 10 minutes later. This car has a brand-new battery and purge control solenoid (after a check engine light) due to this issue, thinking it would fix it.

Purchased Car with 17,000 miles on it. At 35,400 miles I had an electrical issue, cars was driving slow and jerking, sputtering while on the highway. the EMP ? light came on. I brought to the Clear Lake Volkswagen and they had to change our alot of the electronic system. I drove my car for about 9 months and my battery that was brand new died. There was a something with the electronic system. All along since I have owned the car, it would randomly stall when I would come to a stop. Never a big issue and just thought it was something with the stop/start. Last week while driving on the highway, 4-7 times when I would just take my foot off the gas the car would stall. I would have to pull off the the side of the highway, (NOT SAFE) put car in park and start it again. I again brought it to the dealership and they told me it is the Carbon gasket filter along with a clogged fuel line. I am hearing that has happened alot. I AM SELLING THIS CAR AS SOON AS I GET IT BACK. It has had engine issues since 6 months owning. NEVER BUYING VOLKSWAGON AGAIN.

Bought this vehicle new from dealer. Have had all maintenance done at the suggested intervals by VW. Have had ongoing issues with “check coolant” alerts. Coolant has been low on multiple occasions but dealer assures there is no leak. I’m am now out of warranty and car has lost coolant again, well below the minimum level required. Please help with ongoing issues that now dealer will not cover. Being inspected now for water pump failure, radiator core, etc. I feel as though this coolant level problem is being hidden and pushed along until customers are out of warranty. Please help.

Engine stops occasionally while driving and the car is moving. This has occurred even with Start/Stop turned off and while the vehicle is moving on the road. This has occurred several times over the past year. Typically the car can be re-started right away, although on a couple of times it was disabled (would not start) until multiple attempts over 5 minutes.
