2019 Volkswagen Tiguan

My vehicle will have a slow start when I start the car and also a delay when it is at a stoplight. I took it in for service twice and they told me it was because I had an after market battery. However - yesterday my car completely went dead at a stop light and I had to turn the engine off and in. It often lags or stops at a light. According to Reddit it seems it’s a crank start issue.

The car is burning a large amount of oil. I have taken it to the dealer for an oil consumption test 3 times. Every time, VW has indicated that the problem is normal. A tech stated that it is normal to burn a quart of oil every 1000 miles between oil changes. The engine has not ceased yet but it is a real fear of mine, especially since I drive my son in this car.

Me and my family were driving to Los Angeles on a freeway. All of a sudden the car showed a warning saying something like "Limited to 4,000 RPM", and we felt strong vibration under the hood. We decided to pull over at a first available gas station. While turning into the gas station, the car refused to go and refused to start, making a loud clicking sounds. We had to tow the car to the nearest VW dealership (Galpin VW). Later they informed us that they have to replace fuel injectors and harness and it will cost us approximately $2,600. After paying the amount, I found that VW issued a recall/bulletin for this very problem - VWP-23-03 for my model year (VW Tiguan 2019). I contacted VW but they refused to honor the warranty claiming that the warranty does not apply to my VIN. It seem obvious to me that this is the same exact problem as described in the bulletin VWP-23-03. I feel like VW has made a mistake by not applying this bulletin to my VIN number (and probably others) and is endangering motorists that would otherwise get this serious issue fixed during regular maintenance.

I was driving on a hot day and all of the instrument panel, air conditioning, all controllers, like signaling, windshield wipers, radio and all electronic gear turned off. Without the equipment and tools available, I could not change lanes or come to a stop safely. It would be difficult for me to say if other systems were affected. I was luckily not going very fast at the time and was able to navigate to the shoulder and stop my car without incident but it was a very stressful situation that I had never experienced in a vehicle before that time. Yes, my vehicle is available for inspection. This happened for the first time today so I have not tried to reproduce the issue. However, many others have complained about it on forums. Here is one of many examples: [XXX] A car's electronic systems should not completely turn off because of changes in the weather.

It’s happened twice in extreme heat; the first time I was driving not even 3 minutes after starting the car. All of a sudden there was a screen on the dash that popped up and said “ignition off, please stop the car safely”. The car was still able to drive but nothing else was working- gas gauge, speedometer, a/c, radio, etc. The second time happened when I had just started the car. Let it run for about 2-5 minutes and then the dash said “check starter system”. Is still fully capable of reversing, driving but just nothing else electrical working.

I have a 2019 VW Tiguan with 2.0 liter turbo 4 cylinder and auto trans. I am experiencing frequent delayed acceleration from standing start in duration of 2 - 6 seconds. This BW is equipped with Drive By Wire technology which means an electrical wire with a solenoid at each ends sends a signal to motor to rev up. If that signal is not perfect the car suffers from a delay in acceleration from stopped position. I have reported this twice to NHTSA since Aug 2019 when car was newly purchased. Within first week I experienced a “delayed acceleration” from stop and under 1800-2000 rpm’s and under 25mph so this is NOT turbo lag as service manager first suggested. This always occurs from a dead stop pulling into traffic whether left, right or straight away driving. The delay occurs about half the time 5 out of 10. Fortunately for me the six second delay event occurred in church parking lot. During these episodes the engine remains at idle with the accel pedal fully depressed to floor, and at end of the event motor races and car takes off. To repeat there is NOT a mechanical linkage for accel pedal to motor, with “Drive By Wire” technology. There are literally thousand of reports online about these failures and a cottage industry has sprung up to decrease these “delays” (Roar Pedal etc) but they are ineffective. I believe this “drive by wire technology “ is a means that an auto mfg attempts to meet EPA city CAFE fuel requirements. I have requested VE replace one or both solenoids but they refuse until they can replicate the issue and BE corporate isn’t listening and a new 2023 Tiguan I test drive for comparison suffered same issue but less frequent in short 30 minute drive. It is up to you to investigate and require auto manufacturers to correct this major problem in public confidence in auto mfgs and regulatory organizations tasked with protecting the public.

Road trip from VA to NJ approx 700 mi. Mid-trip, stopped for fuel and oil check. Thereafter, engine started to run rough. Check engine MIL on. Could not find any problem. Back on road. Received a low engine oil warning. Checked engine, oil all over back of engine compartment. Shut down engine and towed to nearest VW dealer. Found engine dipstick not completely seated. I checked and measured force needed to completely seat dipstick, at 30 lbs. Dipstick insert sleeve is plastic. Dipstick can be inserted to bottom w/o seating. Any leakage of vacuum from this engine causes extreme performance problems. Oil spewing in engine compartment is a significant fire hazard.
