2022 Volkswagen Tiguan

VW Tiguan lost significant acceleration while driving on the highway. Vehicle check engine light came on. Felt like vehicle was going to stall and decelerated to a below highway required speed. Vehicle was inspected by a VW authorized service center and . Verified GFF found DTC's P0431, P04F0, P24D6, and P2101 were in fault mode. Significant oil leak also occurred. Failed component was crankcase pressure regulator and lower oil pan and gasket (due to increased pressure from failed PCV valve.) This was of great concern as the deceleration was significant while on the highway which could cause potential life threatening accidents.

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.

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)

An issue occurs intermittently when accelerating from a stop/at low speeds. When pressing the gas pedal, there is approximately a 3-4 second delay before the engine kicks in. Theres is no acceleration during those 3-4 seconds and suddenly, the engine will jolt you forward. This presents a safety issue when pulling out on to a street and this vehicle will not move forward. There have been 2 instances where I have almost gotten hit/involved with road rage due to this issue.

The car has a severe hesitation when accelerating from the stop. This hesitation is dangerous in regard that when you try to accelerate from a stop sign into traffic, the car can sluggishly bog down exposing you to oncoming traffic. The issue is more severe after cold start, but can happen anytime. Has caused me to pull out in front of traffic many times only to bog down and nearly be in an accident.

Vehicle has hesitation during cold acceleration. If vehicle is started, pulled to end of short driveway, then go to accelerate onto road, vehicle hesitates and stumbles at times, not wanting to move properly and safely enter roadway. Tried accelerator pedal position reset and no change. This is a common VW Tiguan issue. No fix for it and dealer does not want to acknowledge that it exists. Simply looking on this site and a quick internet search will confirm it exists and is a common issue. And very well could be a significant safety issue when pulling into traffic. In addition, our tiguan also burns an excessive amount of engine oil with no repairs wanting to be made by VW and now has a p2402 code causing engine light to come on all the time. Numerous troubles that are adding up fast and no help or support from VW and its dealers.

My VW hesitates when I step on the gas during first use. This condition will continue until the vehicle warms up. The hesitation will cause the vehicle to speed up very fast. It’s a safety risk when I enter traffic, either on a highway or on a local road. That’s because when I pullout in front of on coming traffic, the vehicle will not get up to speed in a timely matter and then it will speed up very quickly. It will hesitate and jerk back and forth. I’ve learn now that I can not pull out into traffic until I don’t see any oncoming traffic. The dealership is unable to repair because they are awaiting on a software update that VW is working on for the vehicle because I’m not the only one with the problem. No warning lamps or messages. It always happens when the vehicle is first started after sitting for several hours. It first appears a few months after I purchased the vehicle.

Cylinder #2 Misfire, Multiple Misfires. Codes P030200 and P030000 after car sat idle for 20 minutes. Dealer unable to recreate issue. Stating “bad gas” because they are unable to figure it out. Taking it to separate dealership for investigation/second opinion. Car is filled at same Shell gas station and has been for the past year. Bad gas is just not true. Several owners experiencing same issue and injector harness is being replaced. Please investigate.
