2020 Volkswagen Tiguan Problems: 10 Known Issues

On the 2018-2021 Volkswagen Tiguan, owners report the panoramic sunroof glass shattering while driving, with a loud noise and glass falling into the cabin, and say nothing struck it. It affects second-generation Volkswagen Tiguans with the panoramic sunroof, per owner complaints on 2018, 2019 and 2021 models. Mileage when it happened, as stated in the linked owner reports: 5,900 miles on a 2019, 7,000 miles on a 2021, 20,000 miles on a 2019 and 43,000 miles on a 2018.

On the 2018-2022 Volkswagen Tiguan, the accessory rear hatch spoiler may not be properly adhered to the vehicle because the installation instructions supplied with it were not correct. The spoiler can come loose or fall off and become a road hazard for other traffic. It affects 2018-2021 Volkswagen Tiguan (long-wheelbase) and 2022 Tiguan models that had the genuine Volkswagen accessory rear hatch spoiler installed at the port or by a dealer before first retail sale (VW recall 66N5, NHTSA 22V226; 6,553 vehicles in the US). Vehicles without the accessory spoiler are not included. Only a Volkswagen dealer can confirm by VIN.

On the 2018-2021 Volkswagen Tiguan, on some sunroof-equipped Tiguans the front sunroof drains can become blocked with moist debris, letting water leak into the passenger compartment. Volkswagen also found leaks at the front headliner, vanity lights and overhead console caused by poor adhesion of the sunroof body-side seal. Service action 60E5 covered 2018-2019 Volkswagen Tiguans with a sunroof and expired December 31, 2021; seal bulletin 60-19-04 applies to VINs up to AX_KM088514. Volkswagen's sunroof leak warranty extension (VWP-23-06) lists 2018-2021 Tiguan, for 7 years or 80,000 miles from the original in-service date, prorated after the new-vehicle warranty.

On the 2018-2023 Volkswagen Tiguan, owners report the Front Assist collision-warning and emergency-braking system triggering early or braking suddenly with no collision threat, which they worry could lead to being rear-ended. A class-action settlement covering Tiguans with this system was reached in 2024; Volkswagen states there is no defect. Owner reports cover second-generation Tiguans equipped with Front Assist from the 2018 and 2019 model years. The settlement (Dack v. Volkswagen Group of America) lists 2018-2023 Tiguan. Mileage when it happened, as stated in the linked owner reports: 3,500 miles on a 2018, 5,500 miles on a 2019 and 24,321 miles on a 2019.

On the 2009-2021 Volkswagen Tiguan 2.0L TSI (EA888), volkswagen extended warranty coverage for failed engine water pumps, thermostats and thermostat housings on Tiguans under class-action settlements, including a share of the cost of engine damage directly caused by such a failure. The extensions cover Tiguans in the settlement classes: 2009-2014 Tiguan (VWP-19-08: water pump, 10 years/100,000 miles) and certain 2014-2021 Volkswagen models including Tiguan (VWP-22-06: water pump, thermostat and thermostat housing, 8 years/80,000 miles). Both periods count from the original in-service date, so coverage may already have ended. Only a Volkswagen dealer can confirm eligibility by VIN.

On the 2018-2021 Volkswagen Tiguan, owners report the rear brake pads and rotors wearing out well before the front brakes. One owner reports a rear inner pad worn to the metal backing without the wear warning sounding. Owner reports cover second-generation Tiguans from the 2018, 2019 and 2020 model years. Mileage when it happened, as stated in the linked owner reports: 79,200 miles on a 2019.

On the 2018-2023 Volkswagen Tiguan 2.0L TSI (EA888), owners report the 2.0L turbo engine needing oil top-ups between scheduled oil changes, with the low-oil warning coming on and no visible leak. Owners say dealers told them about a quart per 800-1,000 miles is normal. It affects second-generation (2018 and later) Volkswagen Tiguans with the 2.0L TSI engine, per owner reports on 2018 and 2019 models. A 2024 US lawsuit about 2022-2023 Tiguans alleges low piston-ring tension; it is an allegation, not a finding. Mileage when it happened, as stated in the linked owner reports: 10,400 miles on a 2018, 15,900 miles on a 2018, 21,748 miles on a 2018, 33,500 miles on a 2019 and 35,000 miles on a 2018.

On the 2018-2020 Volkswagen Tiguan 2.0L TSI, volkswagen extended transmission coverage on 2018-2020 Tiguans for a diagnosed condition of transmission hesitation and/or jerking. Before diagnosing it, dealers must first perform emissions recall 24GB, an engine and transmission control module software update that Volkswagen says also improves drivability. It affects 2018-2020 Volkswagen Tiguans (US) included in emissions recall 24GB. The warranty extension (VWP-22-16) runs 12 months or 12,000 miles, whichever comes first, counted from the end of the original New Vehicle Limited Warranty, so it may already have ended for your vehicle. Only a Volkswagen dealer can confirm eligibility by VIN.

On the 2018-2020 Volkswagen Tiguan, owners of 2018 and 2019 Tiguans report the engine failing to restart after an automatic Start/Stop stop, needing jump starts or several key cycles, and one 2019 owner reports a 12-volt battery-low message that keeps returning after a dealer battery replacement. A Volkswagen technical tip says Start/Stop is disabled when the battery charge reading drops below 12.1 volts, and that a replaced battery or battery monitoring module that was not adapted to the vehicle can disable it and lead to premature battery failure. Owner reports cover second-generation Tiguans from the 2018 and 2019 model years. VW technical tip 27-19-01TT lists 2018-2020 Tiguan (long-wheelbase) with automatic transmission. Mileage when it happened, as stated in the linked owner reports: 32,000 miles on a 2019, 39,000 miles on a 2018 and 53,000 miles on a 2019.

On the 2020-2022 Volkswagen Tiguan, owners report the fuel gauge not resetting after refueling, for example still reading empty after a fill-up. On some early 2020 Tiguans with 4Motion and the digital cockpit, Volkswagen traced this to an instrument cluster software configuration error. It affects 2020-2022 Volkswagen Tiguans (second generation), per owner reports on 2021 and 2022 models. Bulletin 90-20-01 applies only to 2020 Tiguan with 4Motion and the digital cockpit cluster, VINs AX_LM001000 to AX_LM026215. Mileage when it happened, as stated in the linked owner reports: 56,000 miles on a 2021.
