2018 Volkswagen Tiguan Engine Problems

While driving 70mph on the interstate in the middle lane with an 18-Wheeler next to me in the right lane, my can all of the sudden a warning for an over the 4000 max rpm and an EPC light, which caused my car to start loosing speeding no matter how much or hard I pressed the gas peddle, in a matter of a minute my car dropped from 70 mph to 40mph and had to hit my flashers.

I own a 2018 Volkswagen Tiguan with approximately 70,000 miles. The vehicle requires a full cylinder head replacement due to faulty valve seals. I have been having to add engine oil frequently between oil changes. The repair has been confirmed by an authorized Volkswagen dealership. The required cylinder head part is currently on manufacturer backorder with no estimated time of arrival. Dealership told me to check in every 2-3 months, as no additional cylinder heads can be ordered due to excessive backorder. Dealership charges $6,000+ for this repair. Volkswagen has not provided a solution or timeline for repair with this ongoing issue. There were no warning lights prior to the issue, and the vehicle has been routinely maintained. A major engine component failure at this mileage raises concerns about a potential defect rather than normal wear. This situation creates a safety and reliability concern, with no reasonable repair timeframe due to parts unavailability as well as no communication from Volkswagen regarding this ongoing issue.

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.

The contact owns a 2018 Volkswagen Tiguan. The contact stated while driving approximately 55 MPH, the vehicle started to lose motive power, with an abnormal sound coming from the engine compartment. The contact stated there were several unknown warning lights illuminated. The contact was able to exit the highway however, the vehicle failed to accelerate above 20 MPH. The contact drove back to the residence, shifted into park(P) and turned off the vehicle. The contact not driven the vehicle since parking the vehicle. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 44,000.

The contact owns a 2018 Volkswagen Tiguan. The contact stated that after coming to a complete stop at a traffic light, the vehicle lost motive power. The check engine warning light was illuminated. The vehicle was towed to the dealer; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 140,000. The VIN was unavailable.

Engine failure at 72,614 miles. Volkswagen refusing to assist.

I took the vehicle in to the local dealership for an oil change and after the oil change was completed, I drove about 10 miles before the engine seemed to lose power an misfile. The "Check Engine" light started flashing before it turned solid. I called the dealership and they asked me to bring the vehicle back. After scanning the vehicle OBD information, per the dealership invoice, it returned the following codes: 1. P0343001 (Camshaft Pos. Sensor Circ. High Input) 2. P0300001 (Random/Multiple Cylinder Misfire Detected) Eventually, they contacted VW and were asked to drain the oil, in which they found metal particles. VW then requested them to tear down the engine at which they noticed "excessive amounts of metal on bottom of oil pan". Upon reporting back to VW, dealership was asked to replace "long block with turbo assembly due to metal contamination". My understanding is that the entire engine has been replaced along with the turbocharger. Car was at dealership for 59 days total.

I GOT A NEW JOB WITH A SIGNIFICANT RAISE AND WAS SO HAPPY I REWARDED MYSELF WITH A BRAND NEW 2018 VW TIGUAN (SEL PREMIUM R-LINE). BESIDES SOME SEEMINGLY INCONSISTENT HESITATION WHEN TAKING OFF FROM START, THE CAR HAS A GREAT RIDE, THE STEERING IS GERMAN AND LIKE NO OTHER. THE ADAPTIVE CRUISE CONTROL SAVES ME SO MUCH STRESS ON MY 40 MINUTES DRIVE INTO WORK. SOUND GREAT RIGHT? WELL, IT WAS, UNTIL....I GOT MY FIRST OIL CHANGED ON TIME, LIKE I SHOULD, THEN AT ~14,500 MILES IN MAY 2020, MY LOW OIL LEVEL LIGHT CAME ON. I CHECKED THAT THERE WERE NO VISIBLE OIL LEAKS IN THE DRIVEWAY OR UNDER THE CAR, THERE WEREN'T. I CALLED THE DEALER TO CONFIRM I WASN'T NUTS AND THAT MY OIL WAS CHANGED ~4,000 MILES AGO. THEY SAID I SHOULD ADD OIL, THAT IT'S NORMAL FOR VOLKSWAGEN'S TO BURN THROUGH A LOT OF OIL. SO I ASKED WHAT TYPE OF OIL WAS USED IN THE CAR SO I COULD BUY THE SAME TYPE. THIS WAS VERY ALARMING THAT I WAS ADDING OIL TO A CARE WITH ONLY ~14,500 MILES. I THOUGHT, OKAY, MAYBE THEY DIDN'T ACTUALLY CHANGE MY OIL, MAYBE IT'S A FLUKE. SO I ADDED THE OIL AND THE LOW OIL LEVEL LIGHT TURNED OFF, SO I PROCEEDED DRIVING IT AS NORMAL. NOW, I'VE BEEN WORKING FROM HOME DUE TO COVID-19 SO I'VE BEEN DRIVING VERY MINIMALLY. I PUT ~1000 MILES ON THE CAR SINCE ADDED OIL AND THE LOW OIL LIGHT CAME ON AGAIN ON 8/28/2020. I PARKED THE CAR AND CALLED AND MADE A SERVICE APPOINTMENT AT THE DEALERSHIP. I DIDN'T DRIVE IT ALL ALL OVER THE WEEKEND, THEN TOOK IT IN ON 8/31/2020. THE SERVICE GUY CHECKING ME IN TOLD ME "VW CONSIDERS IT ACCEPTABLE FOR THEIR CARS TO BURN THROUGH A QUART OF OIL EVERY 1,000 MILES." YOU HAVE TO BE KIDDING ME. THIS CAR DOESN'T EVEN HAVE 16,000 MILES ON IT YET. THIS IS NOT OKAY AND NOT NORMAL. SO HERE I SIT ON 9/2/2020. THE DEALERSHIP STILL HAS MY TIGUAN AND ARE RUNNING WHAT THEY SAY IS A NEW SERIES OF TESTS TO CHECK WHAT COULD BE CAUSING THE CAR TO BURN OIL.

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.

THE CAR HESITATES ONE TO TWO SECONDS FROM A STOP WHEN THE ACCELERATOR PEDAL IS DEPRESSED QUICKLY HALFWAY OR MORE AS YOU WOULD DO TO MERGE QUICKLY INTO FAST MOVING TRAFFIC. THE PROBLEM CAN ALSO BE DUPLICATED WHEN MOVING SLOWLY AROUND 5 MPH. THIS PROBLEM HAS EXISTED SINCE THE BEGINNING BUT NOW SEEMS TO BE GETTING WORSE. I CONSIDER THIS A SAFETY ISSUE SINCE THE CAR DOES NOT RESPOND AS EXPECTED/REQUIRED UNDER ALL CONDITIONS.

WE PURCHASED 2 2018 VW TIGUAN. VOLKSWAGEN TIGUAN EXPERIENCE LOSS OF ACCELERATION CREATING A DANGEROUS AND RISKY ENVIRONMENT FOR MY DAUGHTER. VISITED DEALER FEW TIMES AND THEY TOLD ME PROBLEM CAN NOT IDENTIFIED. THEY EVEN TAKE CAR FOR OVERNIGHT RIDE AND CANNOT DUPLICATE PROBLEM. BESIDES LOSS OF ACCELERATION, THERE ARE LOT OF PROBLEMS WITH THE START STOP SYSTEMS WHICH ALSO CAN NOT BE IDENTIFIED. WHEN THERE WILL BE A FORMAL COMMUNICATION FROM NHTSA REGARDING THIS MATTER ?

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.

AT 2982 MILES ENGINE LIGHT CAME ON START/STOP ERROR WHEN CAR WAS MOVING THERE WAS RPM DROP AND ROUGH ENGINE.. DEALER DIAGNOSED MISFIRE CYLINDER #2 , POURED ADDITIVE IN FUEL, TOLD ME CAR WAS ROAD TESTED INVOICE SHOWS SAME MILEAGE IN AND OUT. AT APPROX. 7400 MILES THE SAME IDENTICAL THING HAPPENED WHEN I WAS DRIVING. THE CAR WAS TOWED TO DEALER MAY 13, 2019. DEALER INFORMED ME MAY 15, 2019 THERE WAS MISFIRE CYLINDER # 2 AND CYLINDER #4. CAR IS STILL AT DEALER AS OF TODAY MAY 2019. THESE MISS FIRES ARE A DRIVING HAZARD, THEY CAUSE RPM TO DROP, CAN CAUSE ENGINE SHUT DOWN LOOSING POWER STEERING AND POWER BRAKES. MISFIRES VERY COMMON ON VW / AUDI 2.0 TSI ENGINES. VW / AUDI STALLING CUSTOMER WITH FIXES THAT DON'T WORK. PLEASE INVESTIGATE.

CAR ENGINE CUTS OUT FOR A FEW SECONDS THEN ACCELERATES AFTER COMING TO A COMPLETE STOP

VEHICLE HAS A SIGNIFICANT HESITATION WHEN STARTING FROM A STOPPED POSITION. WHEN PULLING INTO TRAFFIC YOU STEP ON THE GAS AND INITIALLY THE VEHICLE DOES NOT MOVE WHICH CAUSES YOU TO PRESS FURTHER ON THE ACCELERATOR PEDAL. EVENTUALLY VEHICLE SUDDENLY JERKS VIOLENTLY FORWARD. DEALERSHIP ADVISES THAT SINCE THERE ARE NO TROUBLE CODES THERE IS NOTHING WRONG. HAS BEEN AN ISSUE SINCE NEW.

During the life of a 48 month lease, the EPC and emissions control module failed four times, placing the vehicle out of service for at least 40-days total. When these components failed, a message popped up stating there was a 4000 RPM max. The ability to accelerate was immediately lost, and actually the vehicle not let me exceed 2000 RPMs. I had to pull over and restart the engine in order to continue my journey. This was extremely hazardous.

EVERYTIME I DRIVE WHEN ENGINE IS COLD, IT FEELS LIKE ENGINE IS GOING TO DIE. I CAN FEEL SMALL JERKING, LIKE CAR IS RUNNING OUT OF FUEL. FUEL TANK IS FULL. I READ MANY COMPLAINS AND FORMS, VW DOESN'T CARE. I CONTACTED THEM VIA TWITTER, NO RESPONSE YET.

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.

THE VEHICLE HAS SEVERE ACCELERATION PROBLEM, WITH UNEVEN AND UNPREDICTABLE ACCELERATION WHEN STARTING THE VEHICLE FROM A STOP. THE PROBLEM DEVELOPED AFTER THE VEHICLE WAS 2 WEEKS OLD. THE VEHICLE WAS TAKEN INTO THE DEALERSHIP AFTER THE CHECK ENGINE LIGHT TURNED ON. THE DEALERSHIP STATED IT WAS AN ISSUE IN THE SECONDARY AIR SYSTEM, BUT THEY WERE NOT SURE WHAT AND COULD NOT FIX IT AT THAT TIME. THE CHECK ENGINE LIGHT THEN TURNED OFF. THE VEHICLE WAS TAKEN IN TO TWO SUBSEQUENT DEALERSHIPS WITH THE SAME ISSUE, BUT THE DEALERSHIP STATED THE CAR WAS REPORTING NO PROBLEM, AND THE CHECK ENGINE LIGHT WAS NOT TURNING ON. A THIRD DEALERSHIP FOUND A FAULTY VALVE IN THE SECONDARY AIR SYSTEM, DESPITE THE CAR REPORTING NO ISSUES AND THE CHECK ENGINE LIGHT FAILING TO BE LIT. DESPITE THE REPLACEMENT OF THE PART, THE VEHICLE STILL HAS UNPREDICTABLE AND UNACCEPTABLE ACCELERATION, WHICH POSES A SEVERE SAFETY RISK WHEN PULLING OUT INTO TRAFFIC. WHEN I EXPECT THE VEHICLE TO ACCELERATE, IT DOES SO AT AN EXTREMELY TEPID PACE, CAUSING TRAFFIC TO NEED TO SLOW RAPIDLY BEHIND THE VEHICLE. OTHER TIME IT BEGINS TO ACCELERATE NORMALLY, AND THEN STALLS IN ACCELERATION. THIS AGAIN POSES A SAFETY RISK TO THE DRIVER AND SURROUNDING TRAFFIC.
