2023 Volkswagen Tiguan Fuel system Problems

“From a cold start, the vehicle seems to have an issue with fuel/acceleration. When pressing the gas through an intersection, the vehicle seems starved for gas and does not accelerate and almost stalls. This is very dangerous in a city environment, as the gaps between cars is sometimes small. There are no warning signs, just reports from several of my drivers experiencing the same issue with the same vehicle. We just purchased 13 of the same vehicle.”

“I am filing a safety complaint regarding my 2023 Volkswagen Tiguan SE R-Line with approximately 54,000 miles. The vehicle experienced a significant engine-related failure involving the oil separator/PCV system. Volkswagen diagnosed a failed oil separator/breather that caused excessive crankcase pressure, resulting in substantial oil expulsion and damage/leaks involving the plastic/composite oil pan and timing-chain cover. Volkswagen also identified oil contamination around engine sensors and a P0341 camshaft-position fault. …”

“Malfunction with power delivery/transmission: I often experience inconsistent acceleration/power while driving at low speeds, the loss of power and jerks feel very similar to an engine misfire. Safety Risk: This behavior is very dangerous as we instinctively push down gas pedal to overcome lack of power and it causes the car to rocket forward as too high throttle has been opened and one can easily lose control and crash. Occurance: I feel this loss/inconsistent power situation happens at cold start and once the car is warmed up it doesn't occur anymore. …”

“Acceleration fails or hesitates on acceleration from zero mph. This has occurred every day since new (June 2023) and only happens for 5 minutes after start up. It feels like it is going to stall out, but so far it has not. Each time I accelerate for the first time, my car makes a jerky start. It usually goes away after I've been driving a bit. I've tried letting it warm up a couple minutes, but that does not seem to matter. I took it to the dealer at 3,000 miles and they said they could not duplicate the problem (but the car had warmed up by then) and that I should use B&G gas additive. …”

“The contact owns a 2023 Volkswagen Tiguan. The contact stated that while the vehicle was parked in the driveway, the odor of fuel was present. Upon inspection, the contact discovered a fuel leak underneath the vehicle. The vehicle was taken to the local dealer who discovered a small hole in the seam of the fuel tank. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 10,000.”
