2018 Volkswagen Passat

The contact owns a 2018 Volkswagen Passat. The contact stated that while driving at an undisclosed speed, the vehicle stalled. There was no warning light illuminated. The vehicle was unable to restart and was towed to the dealer to be diagnosed. The vehicle was diagnosed with battery failure. The contact was informed that the battery needed to be replaced. The vehicle was repaired; however, the failure recurred. The vehicle was then towed to a different dealer; however, the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 136,000.

I initially brought my vehicle in for service due to a strong gasoline odor and the vehicle failing to start. At that time, I was informed that no gasoline smell was detected and that the issue was instead a faulty starter, which I authorized for repair. Approximately two weeks later, my vehicle again would not start. I was then informed that the issue was a lower fuel injector, which required additional repairs. Just three days after that service, the vehicle once again failed to start, and I was told this time that the upper fuel injector was the cause. As a result of these events, I incurred a total of $3,946.96 in repair costs across two service visits and was forced to have my vehicle towed three separate times. Before the third visit, I was informed that I would need to pay an additional $1,500, on top of the nearly $4,000 I had already paid. I challenged the accuracy and consistency of the diagnoses at that point, and ultimately, the vehicle was repaired without charging me the additional $1,500. While I appreciate that the final repair was completed without further cost, I am deeply concerned about the pattern of repeated breakdowns, inconsistent diagnoses, and the financial burden placed on me as a customer. The original concern of a gasoline smell appears to have been valid from the outset, yet it took multiple failures, repairs, and significant expense before the underlying issue was resolved.

The contact owns a 2018 Volkswagen Passat. The contact stated that while driving approximately 40 MPH, the vehicle made an abnormal sound and failed to accelerate as intended. There was no warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed with a wiring harness failure. The vehicle was repaired. The contact had received an unknown notice, which was related to the failure. The manufacturer was contacted for reimbursement, and a case was filed. The contact sent the requested documents to the manufacturer; however, the manufacturer failed to call back as the manufacturer had stated. The failure mileage was approximately 55,000.

Battery drains overnight. Started with a boost all dashboard warning lights on, vehicle runs fine all day with many starts and stops, battery dies again overnight. Diagnosed with a bad fuel pump control module that continues to run and does not shut off until all battery power is drained. Mechanic changed the fuel pump control module, cleared all fault codes, and vehicle fixed. I saw a Carfax report for an identical 2018, SEL Premium Passat to mine with the exact same issue of a bad fuel control module in that vehicle Carfax report and realized it was a much bigger issue. I am aware of a similar recall for vehicles up till 2016 model year, but this issue is wider for higher model years. Besides the other identical problem listed below in the Carfax report, I am aware of many other fuel pump control module problems reported to online VW forums and online.

ABS sensor warning lights are coming on showing there is an issue.

We have been having numerous sensor issues. Sensors showing air bag malfunction and with passenger side seat belt on the front right side. We bought the car in used condition from pat lobb toyota of mckinney less than a year ago. Constantly having sensor issues with it.

The contact owns a 2018 Volkswagen Passat. The contact stated that while driving at an undisclosed speed, the infotainment screen failed to respond to touch commands, preventing the contact from viewing the GPS feature. The contact performed a hard reset on the vehicle, but the failure persisted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 70,000.

The catalytic converter on my 2018 Volkswagen Passat failed and the vehicle has been at an authorized Volkswagen dealership since May 16, 2025. The dealership confirmed that the catalytic converter is defective and must be replaced, but the part has been on national backorder with no estimated delivery date for several months. The vehicle cannot be safely driven in its current condition and has been unavailable for all normal use. The issue has been confirmed by the dealership and the vehicle is available for inspection. There were warning lights related to emissions prior to the failure. Volkswagen has not been able to provide a timeline for repair, which has created an ongoing safety and reliability concern.

Car Fuel Pump Leaking. Fuel pump Module failure. There was a recall for this issue on other Volkswagens, but not on the Passat. There are hundreds of cars online with the same issue.

Fuel pump Leak. Strong order of gasoline has been coming from the car. I had a check and the fuel pump is leaking. Other vehicles have been recalled due to this, but the Passat has not been included. This problem has been reported out in several cars including a fire….

EPC light came on & check engine light Car shakes

My oil sensor started blinking while I am driving. I stoped and added oil to the car because the level was in low level. Went to the dealership to check my car in if I do have leakage or if my engine did start to burn oil. They did suggest to come visit them after 600 miles which I did. And after check up they did end up saying yes your car did burn oil around 0.25 quart. And I suggest you to come after 600 miles again. I need that issue to be fixed and they are wasting my time in this unnecessary procedure. It was confirmed that my engine burn oil and I have got extended warranty plus my car was always been serviced by the vw dealership.

I received a check engine light and my mechanic diagnosed the problem and attributed it to an the air pump control valve which was connected to primary engine water pump. A slight leak in the air system was noticed since the check valve failed. The primary engine water pump began to lose pressure over time causing increased tail pipe emissions. I tried to report this issue to VW but fell on deaf years. Since the primary engine water pump was part of a recall i was explaining that the air pump control valve also had to be replaced because the open/close relay stopped working. I spent 820 $ parts + labor to get this fixed and VW does not even want to accept it as a problem. I have been constantly encountering these problems with my VW car. This is a safety issue and hence wanted to report this to NHTSA.

Collision around 45 to 50 mph. Airbags frontal and side airbags didnt deployed Two vehicles invaded my lane and I ran into the second vehicle .

First/only owner of a 2018 VW Passat GP r-line, scheduled maintenance intervals followed religiously and performed by VW; only filled with top tier fuel (mid/premium), no prev. indicator lights ever illuminated until ECM light (no accompanying warning lights) came on while driving at highway speed with Adaptive Cruise Control engaged. Immediate loss of power and shaking vibration upon any attempt to accelerate/change lanes to safely get off of roadway. Once off roadway, all systems shut down and engine turned off for several minutes. Restarted car w/o difficulty, remained parked for 5 more minutes to monitor ECM light which did not return after shut down/restart. Returned to highway while safely merging into lane with conservative acceleration. ECM warning light did not return and vibration/shutterring had ceased. No unusual or abnormal gas mileage readings found upon close monitoring. Vehicle was driven x3 (relatively short distances) with speeds no greater than 65 mph; no return of ECM or any other warning lights. On the 4th drive, while attempting to evade an idiot, accelerator was applied more aggressively so as to avoid a near-catastrophic collision (nowhere to slow down or go to shoulder safely within 0.75/sec) which triggered the ECM light accompanied with loss of power/shuttering/vibration when pressure applied to accelerator. Pulled over, shut down, waited, panicked a little, then restarted engine. ECM light did not reappear after shut down/restart. Vehicle operated flawlessly once more. Injector/fuel system cleaner added to fuel tank and driven 40 mins in Sport mode to burn corrosive buildup effectively. Fuel tank refilled at new fueling station (thinking bad gas was a differential) and no issues since. Codes not showing up when diagnostics are ran. VW won’t fix something that isn’t presenting itself as a problem, at that very moment. 93k miles w/ NO prev. engine/emissions/transmission probs.

Intake Manifold Runner is failing. This could suddenly put the vehicle in limp mode on the open highways, resulting in a hazardous situation due to sudden slowing. MIL light is illuminating and diagnostics from Meineke Car Care Center confirms failure of the Intake Manifold Runner. Similar issues have been noted with past VW models, with Intake Manifold warranty extension to 10 years, 120,000 miles for 2006-2008, 2008-2012, and 2013-2017 model years. It seems the problem continues through 2018 as I reached 90,000 miles with a failure. Volkswagen service specialists was quoted as "that sounds about right" so the problem clearly lingers for the 2018 model years and beyond.

The contact owns a 2018 Volkswagen Passat. The contact stated while driving approximately 30 MPH or at various speeds, there was a delay while depressing the brake pedal. The contact stated that the vehicle was also pulling to the left and the right while depressing the brake pedal. Additionally, the contact stated that the suspension was loose while driving over bumps in the roadway causing the vehicle to bounce. The contact stated no warning lights were illuminated. The contact had the vehicle towed to a local dealer, where it was diagnosed and determined that the front wheel bearings needed to be replaced. The vehicle had not been repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 25,000.

Airbag error notice and cracking sound when turning steering wheel. Error light for cruise control, front end assistance. This is the second time this has occured. It was previously fixed in 2018.

Clockspring. Failed 1st time under recall and was replaced by dealer. Failed 2nd time and replaced outside of recall by indepenent. Failed 3rd time and has not been replaced. This has affected the adaptive cruise control, the electronic stability control, and now it engages the brake system when not called for.

I was driving down the road and the wheel locked up and I lost control of the car. I thought it was just a flat tire. I noticed the tire was flat and brake caliber was lying on the inside of the rim. There was extensive damage to the vehicle, tire, rim, suspension components and brake components. There was no warning and it just happened suddenly. My family and other drivers safety were at risk. The dealership said it was due to impact but their estimate didn't mention or included any of the brake components. The brake caliber bracket is broken and the holes were the caliber bolts attached are elongated. The brake caliber and bracket are protected inside the rim and brakes just don't fall off. It is a VW certified car. I put 4,000 miles since I purchased and the accident happened on November 17, 2021. I have all the components and pictures.
