2018 Volkswagen Atlas Engine Problems

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.

Dealer maintained with oil changes per the schedule. Cylinder head issue requiring engine replacement at 104,xxx miles. 3.6L VR6. This is unacceptable.

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.

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.

ECP light came on and vehicle entered limp mode

Water pump failure of a 2018 VW Atlas with 69000 miles.

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.

The vehicle randomly shuts down when slowing to a halt or after coming to a halt..a prompt to manually restart the vehicle then pops up on he dashboard screen. The most recent event occurred on date below

A dangerous cam shaft failure led to sensors near the cam shaft and a piece of the metal housing being broken off due to the cam shaft failure. The cam shaft failed at normal highway speeds and stopped the engine on the highway. Vehicle is still undergoing repairs at “Automotive Tech, Inc.”

My car engine has cut off a few times all by itself while operating it.

The car started to feel like it had the shivers. Could feel some kind of vibrations of sorts. Some time prior to this the car would stall when it would switch with the engine start stop function. We were told nothing was wrong with it. Prior to the vibrations or around the same time the check engine light went on. We took the car to the dealership and were told we had low pressure in one of the cylinders and near low in some others. They recommended a new engine.

Our 2018 V6 SEL Volkswagen Atlas is the recipient of a defective fuel injection system. Through discussion with VW service and maintenance staff, as well as research in online VW specific forums, there is defective fuel injectors found in various VW Atlas year and differing engine vehicles. Our particular vehicle had a malfunctioning, defective fuel injector (fuel injector for Cylinder 6) which resulted in massive carbon build up. There is no real detection system for a faulty, leaky fuel injector according to VW service. The carbon build up began with misfiring check engine and ECP error codes. Upon taking it to the dealer, we were made aware that the carbon build up also resulted in mechanical failure of components within Cylinder 6. This would affect drivability of the vehicle while on the road, resulting in severe power or ability to drive loss. Other additional factors aside from the faulty fuel injection system, is the valve gasket was also leaking oil through to spark plugs 2-4, which could result in vehicle fire. We are not sure if the faulty gasket is a result of the faulty fuel injector system. The 2018 VW Atlas was a first year model release, and would not be surprised if significant design flaws and defects are a risk with this vehicle.

At approximately 91,500 miles, the "coolant low" warning came on. I pulled over, filled the coolant reservoir (it was only just barely too low). (I keep coolant in the trunk because at 75,000 miles the same thing had happened, with no incident other than needing to be refilled). I was 2.5 miles from the dealership, so I then drove another 1 mile, during which no warnings came on but the vehicle stopped and failed to restart. White smoke came from under the hood and the tail pipe. At the time I was on a road where the speed limit is 45 mph, and I was completely disabled in a middle lane, at high risk of collision with oncoming traffic. It was towed to the dealership, where I was told it would require a complete engine replacement.

My vehicle alerted me that I needed to start my vehicle, while I was driving. I had accelerated to a speed of about 25mph, when I got this alert. My vehicle stalled and I pulled over to restart, but my vehicle would not restart again. I had my vehicle towed to VW of ST AUGUSTINE. I took 2 days for my vehicle to be diagnosed by the dealership. Upon speaking with VW of St AUG, I advised that I had not had any notification of engine lights and/or system failure issues. I advised I was hearing no tapping and/or whining noises at all. This incident was very scary and put my life and other lives in jeopardy. My vehicle was unsafe to operate and I was not aware. I was informed by the dealership that they had no way detecting an issue of this manner without taking the engine apart. I was advised that a pulley inside my engine bent and cause another piece to brake. They are advising I need a brand new engine which will cost $16k to replace. For an issue, no one was aware was going on.

Car turns off while in traffic and the auto start is turned off. Have to put it in park and click the start button. When it stars ABS, park assist, tire pressure and other dashboard lights turn on.

Replaced a failed water pump at 78,831 miles on 11/03/2022 and that replacement part failed again at 98,022 miles on 12/26/2023.The dealer would not cover either replacement. The first was outside vehicle warranty and the second was outside the 12k mile part warranty period. This model/trim was not covered under the class action lawsuit related to water pump failure. I’m reporting this so you are aware that
