2022 Volkswagen Tiguan

At 49,000 miles, all four spark plugs and ignition coils failed and had to be replaced due to engine stuttering and hesitation during acceleration. The check engine light first appeared as I approached a red light to make a timed left turn at a high-traffic intersection during rush hour. The malfunction caused my vehicle to struggle accelerating through the intersection, putting myself and others at risk. A certified mechanic confirmed the error code indicating faulty spark plugs and coils and replaced all components under warranty. However, the check engine light continued to reappear intermittently—sometimes turning off for a week after restarting the engine, other times staying on for extended periods. Despite the initial replacement, the same code concern persisted, and the mechanic replaced the components again under the parts and labor warranty. When the issue continued, I took my vehicle to my regular trusted mechanic, who performed a more in-depth diagnostic. They discovered an excessive and unusual amount of carbon buildup in the fuel injectors, which was likely triggering the engine code and causing drivability issues. This diagnosis resulted in an additional repair expense of nearly $700. The vehicle has not been inspected by the manufacturer, police, or insurance representatives, but the failed components are available for inspection upon request. These issues are unexpected given the vehicle's low mileage, age, and regular maintenance. Total repairs reached nearly $1,300. The hesitation posed a safety risk in traffic and suggests a possible premature system failure. My regular mechanic noted Volkswagen may claim this is “regular maintenance,” though this is not common in similar makes and models like the Tiguan.

My Volkswagen Tiguan suddenly and without warning blew a large amount of smoke out of the exhaust along with oil while driving at highway speeds - causing the cars behind me to lose visibility and possibly be covered with oil further reducing their visibility due to the VW manufacturers faulty crankcase breather/pcv valve. After this happened the car dash lit up with warnings and went into "limp mode" where I was not able to exceed 2500 rpm which is very dangerous when on the highway - luckily for my safety at this point I was on a side road. When I checked the engine I found no oil was left in it, it had been sprayed all underneath and up the back, which reduced visibility in the window. I was responsible for towing it to the dealer and was given no loaner despite being under warranty. Leaving myself and children without a vehicle. The dealer confirmed that my VW Tiguan had a faulty crankcase breather which caused over pressurization and pushed up the valve seals and cracked the oil pan. They only replaced those things and not the fouled spark plugs or oil filter from the crankcase breather failure which can cause more engine damage and dirty emissions.

Oil leak from PVC malfunction Causing stalling, over heating and a huge amount of oil consumption of vehicle. This poses a safety hazards for consumers who commute more than 25 miles to work , drs appts in rural areas etc. I have purchased well over $300USD in the last month on oil alone, taking away from house hold budgets and maintenance of said vehicle. The operant e of making home to our Family's as consumer priority and this is A MAJOR RISK. Made a used car purchase of a 22 Tig for my family and I( 2kids and an [XXX] elderly Grandmother). 3mnths with less than 60k miles INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Excessive oil consumption. Noticed oil consuming at abnormal rate about 1 1/2 years ago. Took it to dealership for diagnosis in July 2024 and was told Cylinder Head needed to be replaced. In the meantime, I was told to frequently check and refill oil as needed. The part was backordered until February 2025 when I went in again for replacement where the dealership completed additional diagnosis. It was decided the cylinder head did not need to be replaced and only the valve seals. These were replaced in February 2025. My oil light came back on after about 2,000 miles on April 30th, 2025. The oil was about a quart low. I topped it off. 3 weeks later the oil light came on again. I checked the oil level on May 24th and only the very tip of the dipstick had oil on it. I filled it up by 2 quarts. I contacted VW May 26th to schedule maintenance appt. On June 6th, I checked oil level again before driving to drop off my vehicle and the vehicle was a quart low.

My vehicles started to consume large quantities of oil. Although VW allows for 1.2 quarts per 1000 miles, putting oil in every 1500-1800 miles is very costly and is probably damaging my engine and increasing emission. The Atlas has the same problem and was the subject of a recall. They did a consumption test for free but said i was at an acceptable level. Driving over 500 miles a week for work is becoming very costly and my warranty period is ending soon.

The car will constantly alarm “travel assist currently not available “. Lane assist is not turned on. It will alarm and shut off and alarm again. There are times when is will alarm 10-15 times in less than a minute. It will also alarm when in park. The alarm is often distracting, irritating and create alarm fatigue. I am unable to have a 5 minute conversation on the phone without having to hang up during your the alarm constantly going off.

I am experiencing excessive oil consumption in my Volkswagen Tiguan. I took my vehicle to one authorized dealership which diagnosed the issue as "pushed up" valve seals and recommended replacement. Seeking a second opinion at another authorized dealership, they diagnosed the problem as requiring a full cylinder head replacement. This significant discrepancy in diagnosis is concerning. I also experienced a significant delay in receiving critical service invoices (dated March 28th and April 14th, received on April 28th), raising concerns about timely notification of potential safety issues. Furthermore, I am aware of a publicly known class action lawsuit regarding excessive oil consumption in the 2022 Volkswagen Tiguan, suggesting this may be a broader issue. My attempts to resolve this with Volkswagen of America have been unsuccessful, with representatives refusing to escalate my concerns and hanging up on me. The potential for misdiagnosis and inadequate repair of the excessive oil consumption issue could lead to severe engine damage, including stalling or seizure while driving, thus increasing the risk of an accident and jeopardizing the safety of myself and others. Furthermore, the significant delay in receiving important service invoices raises concerns that I may not be promptly informed of critical safety recalls or maintenance needs, further increasing the risk of operating an unsafe vehicle.

Upon first cranking the vehicle, vehicle has excessive stuttering while accelerating after driving forward. Occurs after car is parked for 1 hour or more most often. Uphill, downhill, flat all the same. Acceleration causes stuttering for the first few minutes of operations. If you do not disable the start stop feature, prolonged stops at red lights cause the same issue and can lead to serious dangerous pretense for accidents while on the roadway. You have no ability to accelerate out of the way of harm until it smooths out. There is also an intermittent engine light that flashes until engine restart but does not record a DTC code. I suspect foul play in the ECU from VW. They are aware and tracking this issue but offer no solutions. Dealers will not service without DTC code and then it’s not repaired still. This is a severe issue for owners. Issue present for nearly a year now with no resolve.

Steering wheel Travel Assist is disabled which includes Adaptive Cruise Control and Lane Keep Assist. The warning lights flash on and off, sometimes multiple times a second, sounding a loud beeping each time. It is triggered at engine start and persists through all speeds. I have experienced it 0-70 mph. The flashing lights and associated rapid beeping indicating the failure is extremely distracting while driving. Warning lights and warning sounds are designed to alert the driver to a potential safety issue so ignoring the lights and sounds is dangerous in the event it is a different caution/warning. However, also not ignoring it is dangerous because of the frequency of the warnings which causes the driver to look away from the road. After speaking with the maintenance department at my VW dealership, they indicated that this is a widely known problem that is remedied only with the replacement of the steering wheel. There are several other sensors that are triggered by the same issue I was told by the maintenance department. They are uncertain at this time if it impacts the airbag system which is another potential safety concern. The steering wheel can only be ordered after inspection by the maintenance department and there is shortage and/or back order of the part to fix the problem.
