Recently reported FUEL/PROPULSION SYSTEM problems on 2018 Volkswagen Tiguan

The car gets filled with strong odor of gasoline inside the cabin and i was loosing gas at a rapid rate in addition the car was loosing speed. there is also the problem with the sto-start system, once the car was at a stop, the car would not turn over and start again. it would get stucktrying to turn on and at the same time i was loosing gasoline. i had to remove all passengers from the vehicle including my one month grand son due to the strong odor of gasoline. this incidents occured several times during the weekend of november 1 through november 4th when i dropped off the vehicle at the dealership.

As starting the vehicle, the fuel line came off and fuel sprayed all over, the fire department had to come, to make sure it was safe enough to tow. the vehicle had been parked for 2 to 3 hours before attempting to start

Intermittent loss of power (not stalling) during normal driving, entering roundabouts, changing lanes, etc.problem is momentary and requires feathering the accelerator to regain power.problem occurs during normal driving, turning either left or right , in city traffic speeds or on divided highway with speeds of 70+ mph. brought vehicle back to dealer within weeks after purchase and was told they could find no problem. now at about 8000 miles and problem persists. cause of problem is unknown to me. a check of owners forum on internet revealed numerous similar complaints. problem is very dangerous when entering roundabouts or changing lanes on high speed interstate highways.

The vehicle hesitates when accelerating from a stop or occasingly surges under heavier throttle pressure. this is very dangerous and the dealers are telling us this is 'normal' behavior. i see that many drivers have reported this issue. does someone have to get injured before we get taken seriously? volkswagen needs to fix the problem with the engine now.

Since brand new there is a rattle coming from the driver's side pillar. taken twice to volkswagen service and the rattle still there. also the vehicle has shut off completely on two different occasions forcing me to restart my vehicle completely. cold starts vehicle does not accelerate well, feels like when someone is learning how to drive a manual car for the first time and misses the clutch and the vehicle jumps. taken twice to volkswagen service and they said they adjusted the transmission and everything is well. as soon as i drove off the lot it began to do the same thing. worried that the vehicle may shut off completely at an intersection or that there may not be enough power due to lag when necessary.

When starting vehicle (either cold or warm), vehicle has a several seconds hesitation when pushing down accelerator. vehicle does not move, hesitates then lurches forward as if the vehicle is not getting sufficient power to move. vehicle has been to the volkswagen dealer several times and they have been unable to repair. this is dangerous when you are entering a highway or crossing a multi lane road and have to move quickly and the vehicle does not respond.

Tiguan 2018 hesitates to accelerate with a lapse of a few (3 or 4) second before the car finally accelerates after a full stop or from slow speeds. this issue tends to be constant and can be extremely dangerous as it happens when trying to pull from a busy intersection or from any other situation where you need to move quick , its a matter of time before someone gets seriously hurt if vw doesn't come up with a resolution. im now on my second service apointment within a month. seems to be a known issue with this model very frustrating!!!!!

The tiguan experiences severe and dangerous acceleration hesitation when accelerating from a stop or from very slow speeds. there is a significant delay between the accelerator being depressed and the car actually accelerating, which causes an extremely dangerous situation when attempting to merge with other traffic or enter a roadway from a side street. this issue is very consistent, and occurs in all operating conditions (engine warmed, engine cold, automatic gear selection or manual gear selection, in 'sport' mode and in regular driving mode). the issue is present in all driving situations where acceleration from a stationary or slow speed is required.

My vehicle has 2 serious issues. the 1st is the gas/exhaust smell that is inside the cabin. this happens when i am driving for more than a few hours consistently. this tends to happen more when the outside temperatures are over 108 degrees. the 2nd issue is the vehicle does not always accelerate from a complete stop when the gas pedal is stepped on. the vehicle will roll into traffic a little bit and then 2-4 seconds pass and then it will go. it is very touch and go after it does this and it takes about 10 minutes for it to fully be "normal" i have had it at the dealership 2 times for these issues. they keep telling me nothing is wrong with the vehicle. i do not feel safe in this vehicle. both issues happen without reason. it happens on city streets and highways. it happens with or without the "start/stop" system activated. it happens in hot and cold. i use premium gas like they told me i had to do. i do not top off when i get gas. it still continues to happen.

Vehicles hesitates to start from a slow or dead stop. will not accelerate as it should. noticeable lag when shifting and accelerating. engine misfiring at only 3000 miles. very dangerous when turning into traffic or merging on to highways. vehicle gives a false sense of accelerating then stops. this happens reliably over and over.

Guess i'm having the same issue a lot of others are having. sitting at a red light and hit the gas and nothing happens. smells like gas inside the cabin. it's been in service at the dealership for 15 days and they have no idea what the problem is and no eta on the fix. i purchased the car in december 2017.

I purchased my tiguan se 4motion in july 2018 and since i have owned the vehicle i have had issues with the acceleration and noise coming from the passenger side b pillar. the acceleration feels like a turbo lag from the start where the gas pedal is pressed but the vehicle hesitates to respond causing a small "stall". this happens in both drive and sport modes. when accelerating up-hill the vehicle has issues with finding the proper gear and constantly searches for a gear to settle on. the b pillar noise sounds like loud clicking when going over bumps and ruts in the road and even makes a noise when opening the door to its fullest.

Engine on this vehicle is very slow to respond. when i give gas, it struggles to start moving, feels like it is carrying 10k lbs of load behind. i push gas peddle to the floor at a signal light to get away from traffic. car won't respond for about 1 or 2 seconds, then starts to move, but very slow, crawling, then starts to speed up. turbo lag is very bad. i don't feel safe. this appears to be a recurring issue that is being reported from customers. to be frank, the size of the vehicle (larger than other models) does not seem to match the engine size. nhtsa needs to investigate for the safety of other drivers, particularly those who share the same fears.

In the first month of owning the vehicle, the fuel pump and fuel tank had to be replaced. since then the vehicle has displayed intermittent loss of response to the accelerator pedal. this occurs when first shifting into drive, the vehicle will not respond to any input into the accelerator pedal. the engine rpms will hold at 1000 or drop to almost stalling the car. after about 10-20 seconds of this, the car will suddenly recognize the throttle input and will lurch forward. there is no indication of when the vehicle will decide to respond to the throttle input. the b-pillar on both sides of the car started to rattle when the ambient temperature was over ~55 f. this has been serviced once, per a technical service bulletin from volkswagen. the service simply made the problem intermittent. the tsb states that the problem is caused by the air bag modules rubbing on the metal of the frame and body. additionally the tsb procedure instructs the service technician to slide a screw driver between two pieces of body or frame metal, and use a hammer to bend the panels apart from each other. has this be proven to not compromise the structure of the vehicle? the transmission consistently fails to find the correct gear to be in at low speeds or from a stop. when starting from a stop the transmission has a harsh shift in the first 3 gears. the transmission at time will start off in the 3rd gear, with the throttle fully engaged, and will take several seconds to determine that it needs to be in the first gear. by the time it finally shifts into first, it is at the peak rpm's for first gear and will harshly shift into second gear. this is then quickly followed by another jerky shift into third gear. starting the car off in third gear has caused issues for making a turn in a break in traffic to the point where i can no longer reliably deem that to be a safe maneuver.

When the auto start/stop feature is disabled by toggling the button on the center console, the car drives very rough, especially at slow speeds. it feels like the transmission is having trouble shifting gears.

Purchased a 2018 vw tiguan sel in febuary 2018. brought to dealer twice (so far) and bringing it backi tomorrow. has stayed in shop for 5 weeks since purchase. serious hesitation when accerlating. my wife refuses to drive the vehicle in fear of her life !! (and so am i) these cars must be stopped being sold...will not be long before someone is killed....

We purchased our 2018 tiguan in january of this year from momentum volkswagen of clear lake. our car has been in 3 times for service and each time (at 5k, 10k, and 15 miles), i have explained to the service writers that my car has a lag, a stop in the throttle and turbo, where it fails to accelerate immediately upon pushing the gas pedal. this delay / hesitation / and all out stalling is placing me in very dangerous situations while driving.twice in the last week, it has completely stalled (engine does not shut off but car will not go) where i was almost rear-ended on the freeway in one occasion and almost t-boned in an intersection in the other. the folks at the dealership explained this is a 'known characteristic of this vehicle'. not one time, when i was purchasing this vehicle was it explained to me that the tiguan would fail to accelerate and put me in such a dangerous position. i have reported this to vw and my local news media. i find it absurd that this is a known characteristic of the vehicle and not once was this mentioned as the reason until my third visit at 15,000 miles where the depreciation of my vehicle makes it a total loss for me to try to even get a safer vehicle. why in world, has this known failure of acceleration not been repaired in anyway?

The car does not get more than 316 miles to a full tank. it also feels like the transmission is jerking you forward which causes the car to be really sluggish. this is also dangerous when trying to pull out on a busy street. i took it to the dealership and they drove it came back and told me i should only fill up at certain gas stations. they gave me a list and said i have to use only premium gas i. the car and only fill up at these stations if i want the expected gas mileage.
