The 4A-GE's small unbaffled sump lets oil slosh away from the pickup during sustained high-G cornering on sticky tires, momentarily starving the rod (big-end) bearings; the engine also runs very hot oil temperatures (140-170°C is reported without a cooler), which thins the oil an… Repairs typically run $500-$5,000. Severity: high.
First-generation MR2s rust aggressively in structural areas: the frame sections under the rear trailing-arm mounts, the rocker panels and B-pillar/sill junctions, the spot-welded rear fender arch seams, the battery tray, and the steel crossmember behind the front nosecone.

Water soaks the carpets and seats, causes musty… Repairs typically run $150-$900. Severity: medium.
The 1988-89 MR2 Supercharged uses an SC12 roots blower engaged by an electromagnetic clutch with an air bypass valve, and this system commonly stops engaging — or cuts in and out — due to heat- and vibration-damaged wiring, faulty manifold pressure signals, or a failed SC clutch. Repairs typically run $200-$1,500. Severity: medium.
The AW11's C-series transaxle is notorious for jumping out of fifth gear into neutral, typically when backing off the throttle at highway speed. The root cause is worn output shaft bearings sitting directly under fifth gear (aggravated by worn shift detents and synchro hub wear);… Repairs typically run $800-$2,500. Severity: medium.
Because the MR2's engine sits in the middle of the car while the radiator is in the nose, roughly 20 feet of coolant piping runs under the cabin, and the system traps air pockets very easily after any coolant service. Trapped air passes the coolant temperature sensors and gives t… Repairs typically run $100-$250. Severity: medium.
