Volkswagen Tiguan won't shift problems

Within 6 months of purchasing car CPO from dealer, car went into limp mode. Was less than 35k miles, still having same issues at 85k miles. Took to dealer, they said nothing was wrong with car. Car began to have ECU light come on frequently in the middle of driving, took back to dealer. They replaced the fuel injector harness under warranty. Began to have issues with fuel injector misfires, car stalling and lagging at stop signs, sputtering when given gas. When driven for long periods at a time, would intermittently not start. Took back to dealer within a year, spent 1800 on maybe fixes, modules and carbon filter replacement. Same issues. Took back again, spent another 1800 replacing modules. Same issues repeated. Took to a european car specialist as we were frustrated with not getting the vehicle properly fixed for years at the dealer, had the engine walnut blasted for any carbon buildup and fuel injectors cleaned, they diagnosed and said the fuel rail harness is bad. Took back to Volkswagen, they re-evaluated and said there was no issue- my husband had to explain to them that there was a repair just done so code reading would not be sufficient and they needed to get under the car and use a multimeter to diagnose the wiring harness. Service team needs additional training- after doing so they found the fuel harness used may in fact be bad and replaced it a second time. Called VW corporate who was no help and told me we are at the discretion of the dealer and they years of the same issues are just what happens at times when the vehicle is out of warranty. There are thousands of reports online- I have been out of use of the vehicle for at least 6 months in my 5 years of ownership. I cannot believe that VW has consistently faulty product relating to the fuel rail system and has not recalled the vehicles.

EPC light kicks on which is puts your car in limp mode, which is caused by a cylinder head issue. The EPC limits your car acceleration and speed ability, this is extremely dangerous especially on the highway. It’s been a year & Volkswagen is refusing to take responsibility and offer a recall when it’s an ongoing issue with 2021-2022 Volkswagen Tiguans. The cylinder heads have been on back order for a year. This is an issue I believe that needs a nation wide investigation & recall for customers.

I am filing a safety complaint regarding my 2023 Volkswagen Tiguan SE R-Line with approximately 54,000 miles. The vehicle experienced a significant engine-related failure involving the oil separator/PCV system. Volkswagen diagnosed a failed oil separator/breather that caused excessive crankcase pressure, resulting in substantial oil expulsion and damage/leaks involving the plastic/composite oil pan and timing-chain cover. Volkswagen also identified oil contamination around engine sensors and a P0341 camshaft-position fault. The vehicle has previously experienced EPC/check-engine warnings and entered limp mode, creating concern about potential loss of power while driving. The dealer’s repair required replacement of the oil separator/PCV system, oil pan, timing-chain cover and associated gaskets, along with cleaning oil from the engine compartment and sensors. The repair estimate was approximately $2,490, later reduced to approximately $2,300. Volkswagen declined my request for goodwill assistance. I am concerned that a failure of the oil separator/PCV system can create excessive crankcase pressure and cause oil to be expelled from the engine, damage other engine components, contaminate sensors, trigger fault codes, and potentially result in reduced engine power or limp mode. Sudden oil loss or loss of engine power can create a serious safety hazard, particularly at highway speeds or in traffic. This vehicle has also experienced recurring alignment problems, requiring three alignments in approximately six months, raising additional concerns about the vehicle’s overall reliability and safety. I request that the federal safety agency investigate whether oil-separator/PCV failures and their resulting oil loss, component damage, sensor faults, and potential loss of power represent a broader safety defect in 2023 Volkswagen Tiguan vehicles.

The car went into limp mode on an Interstate Highway. It was taken to a VW dealer in Mooresville, NC after two other private garages could not diagnose the problem. Their is a current Factory Warranty Extension for 2017, 2018, 2019 VW Tiguan's. The dealer in Mooresville kept the car for two weeks. Drove it for over 100 miles. They claim They can see the code in the computer but it is not active so VW will not pay for the known problem. I feel this is a safety issue as the car will not only possibly go into limp mode at any time but when stepping on the accelerator when not in limp mode the exhibits another known fault. The engine initially sputters as if it is going to stall then accelerates very quickly.

Catastrophic loss of throttle response and severe acceleration lag from a standstill under high ambient temperatures, presenting an immediate collision hazard. On more than ten (10) separate occasions, the acceleration on this vehicle from a complete standstill has unexpectedly dropped to a dangerous level, performing at or below the speed and power of an un-indicated "limp mode."This hazardous condition is explicitly triggered by ambient heat: it frequently occurs in temperatures above 90°F and consistently occurs when temperatures exceed 95°F. The defect manifests unannounced from a stop while sitting in traffic, idling at a light, or attempting to pull out or merge onto a roadway.Once the vehicle is in motion, the engine runs fine and all auxiliary systems—including the air conditioning, infotainment, and advanced driving assistance systems—operate normally. Crucially, the vehicle displays absolutely no dashboard warning lights, check engine lights, or stored diagnostic trouble codes (DTCs), making the malfunction impossible for standard onboard diagnostics to register. Over time, I have learned to detect a subtle, tell-tale change in the cadence of the engine idle that foreshadows when this dangerous throttle failure is about to occur.Based on the symptoms, the failure appears to reside within the electronic accelerator pedal assembly, throttle body, Engine Control Module (ECM/ECU), transmission control system, or a thermal management software conflict between these components. I have presented this vehicle to an authorized dealership, Lokey Volkswagen, on two (2) separate occasions for this exact issue. On both visits, the service department failed to provide any remedy, diagnostic resolution, or repair suggestions to the lack of stored fault codes.Because this severe lag occurs when trying to accelerate into live traffic, it leaves the vehicle dangerously exposed and creeping along at walking speeds. I firmly believe this defect will result in a severe injury

VW of America initially claimed it was a software update which is false, actual parts defect. Now known defect with turbo R line, as evidenced by multiple reports from consumers across the country, unsafe vehicle to operate as occurs while driving.

2026 Tiguan SEL Turbo R-Line goes into limp mode. Volkswagen originally diagnosed this as a software issue. A software fix was finally released (after two months of waiting) but the 'fix' does not solve the problem. I had the software patch applied at my dealership last week but found the car to be exhibiting the same problem this morning. Car shakes and shudders and goes into 'limp mode'. Due to significantly reduced power, it is not safe to drive.

Started having issues immediately after purchase with turbo issues. Which force the car into am RPM limited limp mode. Made 3 trips to dealer with no resolution. The car has very limited power and is unsafe to drive. We have been asking for a loaner for a couple weeks and are finally being granted one. There seems to be no time for a resolution. The vehicle has basically not functioned correctly since buying it.

On March 12 warning message came on saying emergency drive system not available and then numerous warning lights came on and the car started to shake violently and went into limp mode. I pulled into a parking lot and called roadside assistance. It was towed to the dealership and has been there since. I was told it showed a misfire on cylinder 4 and has a faulty injector.
