general problems of the 2018 Volkswagen Tiguan - part 1

2018 vw Tiguan. The fuel injector harness failed. There is a NHTSA letter stating 2018-2019 Tiguans had this issue and there’s an extended warranty up to 120,000 miles. My Tiguan is at 91,000 miles, but vw is saying the warranty isn’t assigned to my VIN. So there’s a warranty for this exact issue and year, but my vehicle isn’t covered. This warranty obviously needs to be extended by build date as it’s a pretty costly repair.

1)my sunroof/window is leaking. This has caused internal damage. My car had 2-2. 5 inches of water that has damaged by carpeting and pads the 60e5 was performed. ~72,500 miles 2018 Tiguan. 2) dealer service has advised of service:replace set of (4) fuel injector o-rings due to fuel leak at fuel rail-include intake manifold gaket and throttle body gasket.

Coolant burst and started leaking. Unable to drive car. Radiator problem may be related to bad water pump. I see there was a recall.

Seat belt light on. Car went into limp mode while on the highway. Seat belt acted like it was loose. Went for scan and it pulled up diagnostic code p0203 which is replace fuel injector wiring harness. Saying cylinder 3 circuit malfunction. Also threw code p050b.

First purchased this car from a dealership in 2023, used at128,051 miles. Did not have any problems with it in the first year I would say. Then suddenly while driving down the road the epc light would come on limiting my speed to 4,000 rpm. It would come on and off also causing my check engine light to come on and off. It has now become more frequent, the epc and check engine lights will come on and off creating a major hazard while driving. Got it scanned while the check engine light was on and it ran a code for a cylinder 4 engine misfire from my fuel injector wiring rail harness. It looks to be a common problem with this model but it’s showing my VIN is not attached to a recall.

I bought my 2018 Tiguan in 2021 with 20k miles on it from york Volkswagen in york, PA. I'm at 83k miles. My vehicle sporadically stops accelerating, sputters and goes into "limp" mode. Ecp light comes on, engine error warning max rpm. Car stalls in heavy commuter highway traffic, with no shoulder to safely pull off the highway, which is terrifying and deadly. Also stalls/ hesitates in slower city traffic. Dealer initially suggested an early oil change ($130. 00) thinking this might resolve this issue. This is a well known and well documented, extremely dangerous issue. I wonder how many have been killed that we don't know about with the unexpected decelerating and unable to accelerate in speeding traffic. The dealer does not acknowledge this known issue. This has been happening for months. I glad I did some research.

I was on the freeway and my vehicle stopped accelerating and went into limp mode (almost died). I took it to the dealer and they said the codes for fuel injector harness were on and so I need a new fuel injector harness. Vw released an extended warranty for that but the dealer is saying the warranty is VIN specific and my vehicle does not qualify. How can it not qualify if its the exact problem listed on the extended warranty? number: vwp-23-03 (number for the warranty).

Car is hesitating on acceleration.

2018 vw Tiguan, 65,109 miles. Unable to add fuel to the vehicle. The filler neck would back up with fuel and even on the lowest setting, the pump would click off on back pressure. Fuel would often splash out. Gas smell or odor in and around the car. When parked in the garage, the fuel odor was strong. No warning lights or check engine lights were on. Dealer replaced b evapcanist, a c ldpump, af valve. Dealer charged full cost for repairs. After multiple calls to vw consumers assistance, the repair charge was covered under warranty and refunded my payment. Vw should cover or repair faulty emissions controls that cause serious safety issues with gas vapors inside or around the vehicle, and/or contribute to inability to properly and safely fill the vehicle with fuel.

My car has been having issues since I hit 40k in 2022. Each time I took it in to ontario volkswagon for a diagnosis and repair they could find anything because the check engine light was not on. So they would tell me "based on milage this is the service we recommend" the dealer kept telling me its the gas your using bad gas but I only ever pump is mobil, or shell and always use 91. So by them saying that at every visit they knew what it was but failed to properly diagnose it. Fast forward to current date my car at 83k my car has stalled out several time going into limp mode on the fwy. It throws an error warning "max 4000 rpm" the cars check engine light turn on I am unable to accelerate and my speed starts to decelerate you can only imagine how scary this can be with your kids in the car and your car starts decelerating while the cars around you are going highway speed. Before it started with the error message the car would sputter while accelerating onto the highway then what felt like a hiccups when hitting 2000rpm and keeping it at a steady speed. After spending thousands of dollars fixing recommended services and pleading with ontario volkswagon the service advisor finally said volkswagon exteded the warranty on the fuel injector wiring harness but the only way to get it repaired was if the check engine light was on and the error code for that was present at the time of service. My car obviously is experiencing the symptoms but the dealer fails to honor the warranty. This should be a standard recall on this car. My experience was a frightening one and could of gone differently if it happened at a different time of day.

Same issue as reported with NHTSA campaign number 24v110000 fuel has flowed into evaporative emissions and has leaked out of the charcoal canister. The dealership is replacing the following parts- fuel tank evap canister leak detection pump purge value.

Received max rpm 4,000 warning while on long drive. Happened and had to restart car several times. Lost ability to accelerate. Also, when car was on cruise, started shaking.

At 48k miles, fuel efficiency began to significantly drop. At next start up, engine would not turn over and epc light came on. I waited 30 minutes, unlocked the steering wheel and was able to start the vehicle and epc light turned off. I took it into Volkswagen dealership to have it looked over and they could not duplicate the issue nor find cause for lower fuel efficiency. The issue with fuel persisted intermittently. Then at 57k, while driving long distance, I noticed what seemed like misfiring when accelerating above 65 mph. There were no noises, no warning lights, and fuel efficiency seemed about the same. I continued driving and about 6 hours into my drive, epc light came on, rpm's shot up to 4,000 and car began violently shaking while losing significant power and dropped down to 30 mph. I was in the left lane when it occurred and had to quickly move over to the right lane. The car then could not exceed 40 mph with the pedal held to the floor. I turned on my hazards while I continued driving an additional 30 miles to the nearest Volkswagen dealership. Because of how heavy the traffic was and the high speeds of the travelers, it put myself and my passengers at risk from not being able to accelerate, along with the other drivers having to either brake hard or quickly change lanes to avoid my car. At the Volkswagen dealership, diagnosis found code p0204 cylinder 4 injector. They confirmed 4th cylinder misfiring and replaced the fuel injector harness. Since that repair, my car has been shaking at idol, when initially taking off, and if I turn of the start/stop function.

Like many other people who have complained, the same epc engine light turning on after the engine stalls while driving. This has happened multiple times while driving on the highway while going 65mph+. The max speed 4000 rpm message comes on the dashboard. The car does not accelerate and pulling over is necessary in order to shut off the car and restart the engine. This is incredibly dangerous and the car’s speed cannot be controlled.

Epc light came on and engine started to stall.

Like many other complaints, for the second time now an error appeared having to do with 40000 rpm. Acceleration is impossible and the car shakes. We had this replaced for the first time in 2019 on our model year 2018 Tiguan and now need it replaced again. The car is undriveable, unsafe for its passengers and others on the roadway when it suddenly decelerates and won't resume speed. Both times this happened on the highway. There was no advance warning lamp or messages prior to the failure.

While driving on the highway, at highway speed (70mph), an error appeared saying the engine had exceeded 4000rpm, which it hadn't, and then it shut off for "safety". We lost the power steering and brakes at 70mph. We were able to get off the road, stop and restart the car and proceed home. This happened three times. The car is now at the dealer. The car is 18 months old with 20k miles.

Like many other complaints I have read, an error appears saying the engine had exceeded 4000rpm, when it does not. Then the car drops down to 10 mph and will not exceed. The car shakes uncontrollably. The car is 28 months old and has been having these issues since 6 months in. The car has been at volkwagen dealerships for 3-4 weeks at a time 4 times already for the same issues. I have filed multiple complaints with Volkswagen and they have done nothing to rectify this dangerous situation.

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.

�the vehicle significantly hesitates when accelerating from a stop or occasingly surges under heavier throttle pressure while trying to accelerate onto the highway. You have to push the gas all the way to floor to get a response from the vehicle from a dead stop. The vehicle will start to go then act like it is going to stall then start to move. It is very concerning when trying to pull into traffic. This has been an issue since the vehicle was purchased in 2018, but the issue seems to be getting worse as the vehicle gets more mileage. I began researching the issue online and this seems to be a common issue. Please see link: https://m. Carcomplaints. Com/Volkswagen/tiguan/2018/fuel_system/fuel_propulsion_system. Shtml.

This vehicle has significant, but intermittent issues with acceleration; it seems mostly when the ac is on or it is cold out (below 40). Vehicle will hesitate, or entirely not respond, to the gas pedal. When this occurs, acceleration is even less predictable (and slower) than a diesel truck. When it does not occur, the acceleration was zippy and fast. Unfortunately, this erratic lag is extremely dangerous - especially when attempting to merge on the highway. I can step on the gas repeatedly and nothing happens, but then the car will accelerate in a manner which feels out of control. Driving in "sport" mode seems to prevent this, so I am inclined to think there is an issue with how the vehicle has been programmed - versus a mechanical issue with the engine. I know some "eco" modes tend to make cars less responsive to acceleration (in order to save fuel) but this is extreme.

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.

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.

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.

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.

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. . . .
