A seriously damaged tyre and windscreen damage round out the top three. Average tested mileage sits at 30,390, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Best band to buy
95.7%
2021+ registration
the 2021-on band climbs to 95.7% — a 3.4-point improvement. Tests in this band average 26,333 miles — roughly 13K miles fewer on the clock than the older band. Failures here are mostly wear items: damaged but not adversely affecting driver's view, tread depth below requirements of 1.6mm — the structural issues that drag down older examples don't appear in the top-10 for this band. Post-2020 examples are early in their MOT life and generally show the cleanest records.
Band to be cautious about

Verbatim faults logged by owners on honestjohn.co.uk over recent years. We didn't summarise — these are the words people typed in.
What's good
The 2023 Volkswagen Tiguan is an upmarket alternative to SUVs like the Nissan Qashqai and Ford Kuga. It boasts a classy and spacious interior, and is comfortable and easy to drive.
Where it falls short
Looks expensive alongside the very similar SEAT Ateca or Skoda Karoq. Not the most exciting SUV to look at. Other than the R version, not particularly thrilling to drive.
Reader reported several software faults with their Volkswagen Tiguan Allspace. On start up the main dash display changes configuration from previous layout. The set speed of the cruise control jumps 2 or 3mph, up or down, without driver intervention. Sometimes the volume control will work but at other times volume cannot be changed. Although both hands are on the steering wheel a message a message appears reminding the driver to put both hands on the steering wheel.
Gearbox control unit failure reported on 2017 Tiguan. Owner quoted £1100 for repair.
Problems with 2021 Tiguan 1.5TSI 150 Elegance DSG7. Within a week the owner noticed that when driving along with the adaptive cruise control and associated driver assistance systems engaged (lane keeping assist, road sign recognition etc) the display and nav switched to a European speed limit of 110kph.
Infotainment system failure on 2016 Tiguan. Car was four months outside of its warranty and the dealer is willing to pay just 10% towards the £1950 repair cost.
Report of failure of touchscreen function of media infotainment system of contract hired 2016 VW Tiguan at 37,000 miles and three and a half years old. User couldn’t input a destination to the sat nav or change the radio station. Sometimes it would freeze entirely or randomly switch between functions.
Report of 2018 VW Tiguan TDI in for a service and dealer phoning owner to tell him they needed to "drop the gearbox" because he had detected an oil leak due to a loose bolt. Being fixed under warranty, but taking a week.
Report of hesitation and kangarooing from June 2019 VW Tiguan 1.5TSI with DQ381 7-speed wet clutch DSG, now at 1,800 miles.
Report of auto braking of 2017 Volkswagen Tiguan being spuriously triggered.
Report of 2018 VW Tiguan 2.0 TDi BMT 150 4Motion SEL 5dr DSG failing to start on a couple of occasions. Turns over, but does not start. Suspect glowplugs. Suggested owner turns key to first stop, counts to ten to give the glowplugs time tyo heat up, then turns the key to engage the starter.
Report that new VW Tiguan (awaiting details of engine, transmission, drivetrain) could not be registered on a 69 because VW UK has not received the derogation codes from the the VCA so cannot register any cars that are non RDE compliant for 69 plate. This car was built before 31-5-2019 but cannot be registered on a 19 plate either because apparently the period for registering on a 19 had passed already, one day early.
Regarding problems with 1.5TSI engines, owner of Tiguan 1.5TSI wrote, "if you turn off the auto hold and the stop start you will not get the kangarooing or the car switching on and off if you coast the last few yards to a stop with the clutch depressed."
Report of July 2019 VW Tiguan 1.5TSI pulling unevenly (kangarooing) from a cold start. Dealer applied a software update on 26th July but it does not seem to have resolved the issue. We recommended trying running it in superunleaded that the engine is optimised for. See 'Good' 27-7-2019.

Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own a Tiguan R Line Tech Tdi S A and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
