Water in Cargo Area and Spare Tire Compartment on Toyota Supra

The third-generation (MKIII) Toyota Supra has a common problem with the rear hatch leaking water into the vehicle.

Through normal operation, dirt, leaves, or twigs will build up between the hatch and the body causing the hatch seal to deteriorate at a rapid pace. As the problem worsens, the hatch will develop water leaks, and wind noise in the rear of the car will increase. If this issue goes unchecked, rust will begin to develop in the spare tire compartment, and around hatch.

The solution is to replace the rear hatch seal, and thoroughly clean and wax the body where the seal makes contact. If rusting has already begun, the body will require repair.

To help prevent the issue, frequently clean any debris build-up between the hatch and body.
