2018 Volkswagen Tiguan Fuel System Problems

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.

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

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.

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.

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
