1991 Volkswagen Cabriolet

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1991 Cabriolet.

Transmission Automatic 3-spd

The 1991 Volkswagen Cabriolet pairs its engine with a 3-speed automatic transmission, returning EPA fuel economy ratings of 21/26/23 mpg. Routine underhood maintenance demands a 3.7-quart oil capacity using 20W-40, 20W-50, or 20W-20 API viscosity fluids to keep the powertrain properly lubricated. This specific model year sits in a problematic position within the vehicle's reliability history, as 8 total owner complaints—predominantly targeting the gasoline fuel system—alongside 3 recalls suggest that researchers should anticipate potential fuel-system vulnerabilities.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 1991 Volkswagen Cabriolet dominate in one area — the fuel system, gasoline, 5 of 8 reports (62%), well ahead of the next concern. That matters, because the fuel system, gasoline are also the target of recall 92V-058 on this vehicle — so the single most useful check before buying or servicing one is confirming it was actually performed. 0 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the fuel system, gasoline pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
