2018 Volkswagen Passat problems

“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.”

“A major engineering and material design failure occurred involving internal fluid containment seals, resulting in a severe electrical safety hazard. Pressurized engine coolant breached an internal component seal and began migrating internally directly through the vehicle's engine wiring harness via capillary/siphoning action. The fluid used the sealed wiring loom as a literal pipeline, traveling inside the wire insulation to bypass all outer weather seals and completely flood the Engine Control Module (ECM) pin connectors. The vehicle's dealership service department documented extensive galvanic corrosion and shorting inside the primary vehicle computer pins due to this blue-green fluid pooling. Because the dealership has not yet completed the full repair, the exact originating component source of the leak (e.g., the engine coolant temperature sensor or the coolant expansion tank housing barrier) remains unconfirmed. However, the physical mechanism of the coolant migration through the sealed harness into the primary electrical architecture is fully verified. This defect presents a critical safety risk. The sudden flooding and short-circuiting of the Engine…”

“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.”

“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…”

“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.”

“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…”
