2018 Volkswagen Tiguan Problems

What owners report

Owners of this model year most often describe hesitation or delayed acceleration from a stop, which many attribute to the transmission and start/stop behavior, and some describe sudden automatic braking from the front assist system. The sample also includes engine stalling or limp-mode episodes with warning lights, low oil-level warnings, and water leaks from the panoramic sunroof. Many complaints were filed within the first 20,000 miles, and several owners said dealers could not reproduce the concern or described the behavior as normal.

1. 1
   Transmission and drivetrain

   Hesitation or delayed acceleration from a stop

   • 88 complaints (31%)
   • median 7,000 mi at 1.1 yrs old (55 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2017–2026

   Complaints describe a lag of two to several seconds between pressing the accelerator and the vehicle moving, most noticeable from a full stop or at low speeds in the lower gears. Some report the engine revving while the transmission seems not to engage, followed by a sudden surge; others note the engine start/stop feature adds to the hesitation. Owners say dealers either could not reproduce the behavior or told them it was a normal characteristic of the engine and transmission. Often reported in the first few thousand miles, from new up to roughly 20,000 miles, and in stop-and-go traffic or when pulling into moving traffic.

   What to check: During a test drive, try several starts from a full stop and note any delay before the car moves; also ask whether the vehicle has had any transmission or engine software updates.

   2 excerpts from owner complaints in NHTSA records

   “This vehicle has an erratic and often severe hesitation when accelerating, which makes it extremely dangerous to drive on the highway as the driver can not gauge the rate at which the car will speed up. It happens less frequently when driving under 40 miles an hour on a city street but is unpredictable at speeds above this. I've been driving for over 25 years and this is the first vehicle in which I've experience this uneven lag. …”

   NHTSA complaint #11329226, filed 2020-06, 18,000 miles

   “Since owing my 2018 vw Tiguan, it has had an intermittent problem moving forward when I push on the throttle from a complete stop. Sometimes there is a delay of 2 to 3 seconds before the car moves forward. This is very dangerous and could cause an accident.”

   Brakes

   Front assist brakes unexpectedly

   Mentioned in 10 of 60 sampled complaints

   Complaints describe the automatic emergency braking or collision avoidance system engaging with no obstacle present, sometimes at highway speed and sometimes at very low speed in parking lots. Owners mention a warning image on the dash and a sudden hard stop; dealers were often unable to duplicate the event. A related group describes adaptive cruise or lane-keeping systems reacting to vehicles in neighboring lanes. Reported from as little as 60 miles to about 30,000 miles, at both low city speeds and highway speeds.

   What to check: Check whether driver-assistance software updates have been applied, ask whether the system can be adjusted or turned off, and note any history of warnings or brake interventions.

   “Panoramic sunroof LED ambient panel lights recall resulting in darker lighting inside vehicle which makes me more afraid at night and was a false advertisement feature as the original lighting was what attracted me to the vehicle upon lease agreement.no effort has been made to repair the lighting defect caused by recall.”

   “This vehicle has a drive ability problem. The car has a major hesitation and is very dangerous when pulling onto the highway. The car almost cuts out but doesn't stall and find it very dangerous. The dealer told me that nothing is wrong with it. Also, there was a recall on my ambient lighting on my sunroof. There could be a leak or humidity could affect the wiring and could cause a fire.

Buying note. Drive this model year in stop-and-go conditions and from several full stops before buying, check for water damage around the sunroof, and ask for service records covering engine faults, oil consumption, and recall work.
