2018 Volkswagen Tiguan Fuel system Problems

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.

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.

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).

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.

Incident

Dec 15, 2023

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.

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.

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.

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.

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

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.

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.

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.
