Complaint history

When NHTSA received these reports. Changes in reporting alone do not establish a change in failure rates.

Problems owners report

Listed groups have at least 3 complaints. The page includes the 20 largest groups plus any additional flagged groups; some complaints are not assigned to a group.

AI groups complaints by meaning; the groups are approximate. Share ratio compares the problem’s share of this vehicle’s complaints with its share on other vehicles over the last 24 months (shown from 3 recent complaints). A 2× ratio means twice the complaint share, not twice the failure risk. Flags mark unusual shares or recent surges after an AI review of the complaint content. “First signal” does not mean the pattern has persisted continuously.How recall estimates are calculated.

  service brakes, hydraulic: foundation components

  The anti-lock brake/traction control computer logic program was incomplete, resulting in the trapping of brake fluid pressure in the rear brake lines. Failure to release the rear brake line pressure causes a condition where brake pedal application results in activation of the front brake only, and continual rear brake drag.

  Failure to release the hydraulic pressure in the rearbrake lines causes the rear brakes to "drag" and a condition where only thefront brakes are applied when the brake pedal is depressed by operator. Thisresults in early wear of the rear brake lining, increases of stopping distances,and possible loss of vehicle control and a possible accident.

  Remedy

  Replace the defective anti-lock brake/traction control computer, and if any brake system is damaged from the defective operation of the anti-lock brake/traction control system, repair the damage at no cost.
