2018 Volkswagen Atlas: engine overheating

Filed Jul 16, 2026 · Engine, Transmission · CA

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.

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.

Water pump was replaced a few months ago after VW dealer discovering cracked pump housing during routine maintenance. A few days ago a "CHECK COOLANT LEVEL" message was displayed. Immediate check underneath vehicle found no evidence of external coolant leak. However, reservoir coolant tank found to be almost empty. Visual inspection of engine compartment showed all coolant hoses to be intact, cap secure on ball style reservoir tank without evidence of leakage. No odor of coolant in or around vehicle. Research on this problem found hundreds of 2018-2019 VW Atlas owners with identical symptom description, most ended up finding evidence of coolant in engine oil (crankcase). A sample of crankcase engine oil has been sent to an independent laboratory for analysis. The General Manager and Service Manager at VW dealer have been notified of the issue and that it is a known serious problem to VW Atlas owners despite not having risen to the level of a recall. Once VW has completed diagnosis and repair, the plan is to resubmit another sample for post-repair analysis. This vehicle was purchased new from VW and we are the first and only owners. With the exception of tire service and replacement of the battery, ALL other maintenance has been performed at VW. All recommended routine services have been completed on time, by VW per manufacturer recommendations. Let me be very clear on this point: WE DO NOT PLACE ANY BLAME ON THE VW DEALER(S) THAT HAVE SERVICED THIS VEHICLE SINCE WE TOOK DELIVERY. WE BELIEVE THAT THIS IS A MANUFACTURER ISSUE THAT HAS YET TO BE ADDRESSED AND JUST WANTED TO DO OUR PART IN REPORTING FOR THE GREATER GOOD OF ALL ATLAS OWNERS.

My car displayed a warning that my engine was overheating and to pull over immediately. My temperature gauge was at max HIGH and check engine light came on. Towed to dealer. Was told by VW that the secondary coolant pump had failed. It was replaced and then it happened again two days later. My car was towed back to dealer again who cleaned, drained and refilled coolant. Two days later it overheated again and my engine was making a crackling sound. I use this car to transport my three young children and I am afraid to drive it. The car is overheating after driving less than a half mile.

The coolant warning light went on 3 days ago. When I first start the engine in the morning or after hours of parking, the coolant warning light went on. After the engine temperature goes up, I have to turn the engine off and on again to have the coolant warning light disappeared. This is an one year old vehicle which has 10500 miles. I have driven 6 brands of vehicles in my life but this is the very first time to have a coolant problem. I checked that no coolant leaking and shortages.
