Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The contact owns a 1989 Jaguar XJ6. The contact stated that the low fluid indicator light illuminated. He also learned from a mechanic that the brake accumulator switch was leaking hydraulic fluid, which activates the power brakes. While driving 55 MPH, the low fluid indicator light illuminated and the brakes failed. The mechanic replaced the master cylinder for $600, but the failure persisted. The contact took the vehicle back where it was diagnosed with the same failure as noted in recall # 90v023000 (service brakes, hydraulic: foundation components: hoses, lines/piping, and fittings). …”
NHTSA complaint #10196707, filed 2007-07, 85,000 miles“While driving at any speed the charge switch keeps going out, causing the hydraulic fluid to flow out of the vehicle from the brakes. Also, when driving and applying the brakes they become very hard, and do not stop vehicle. This is the third time the consumer has had problems with the brakes.”
NHTSA complaint #835992, filed 1999-03“Brake system failed multiple times-ABS system repeatedly and disc brakes seem to have no hydraulics-pedal hard as a rock. Abs sensor comes on intermittantly even when no obvious problem w/ABS, yet ABS fails often-especially under heavy braking. Electrical: car would die while in operation yet alternator tests fine. Car would not start after sitting-sometimes hours-sometimes days. Car seems to have elec drain from unknown source. Car been to four different service centers w/ over $3k spent. Car been undriveable for over 18 months. …”
