Unknown Complaints

• UnknownService brakesFuel/propulsion system

  I own a 1993 Jeep Wrangler, VIN [XXX], with two outstanding safety recalls: Recall 625 (fuel tank sending-unit gasket) and Recall B03 (parking brake pedal assembly). On [XXX], I delivered my vehicle to Lake Elsinore Chrysler Dodge Jeep Ram in Lake Elsinore, California, for completion of both recalls (repair order [XXX]). On [XXX], the dealership's service manager confirmed in writing that neither recall had been completed because required replacement parts were unavailable or discontinued. The dealership identified unavailable fuel-system recall components and parking-brake assembly mounting components. The dealership has not certified that the vehicle is safe to operate, and the vehicle remains at the dealership. The unresolved recalls involve potential fuel leakage and unintended parking-brake release. I am not reporting a confirmed active fuel leak, an actual parking-brake failure, an accident, or an injury. My concern is that the recognized safety defects remain uncorrected and no completed repair or documented safe-release plan has been provided. I contacted Stellantis Customer Care (case [XXX]). On [XXX], a Stellantis supervisor discussed potentially obtaining alternative parts or authorizing the dealership to use aftermarket components. However, no written authorization, confirmed payment arrangement, parts availability, or repair completion date has been provided. I am requesting NHTSA's review of the difficulty obtaining remedies for these existing safety recalls and guidance regarding the manufacturer's responsibilities and available options for completing the repairs safely.

The horn independently engaged continuously following the air bag deployment, requiring the driver to disconnect the fuses. The contact sustained soreness to the left arm, elbow, forearm, and hand.

  The contact owns a 1992 Dodge Caravan. The contact received a notification of NHTSA Campaign Number: 96V099000 (Service Brakes, Hydraulic); however, the part to complete the recall repair was not yet available. The contact stated that while driving at various speeds, the vehicle would fail to decelerate as intended while the brake pedal was depressed and would require excessive force to come to a complete stop as intended. The vehicle was taken to a local dealer, who advised the contact that the ABS failed and the equipment required to diagnose the vehicle was not available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure via telephone. The failure mileage was approximately 146,772

• UnknownUnknown or other

  The manufacturer sent me three sets of drums that were completely out of round as confirmed by local mechanic and auto parts store. It is visible to the naked eye and causes the truck to shake when brakes are applied and brake significantly more slowly than normal. The manufacturer is no longer willing to replace the brakes or refund the part and says that the parts they sent me are still within specifications even though they caused significant vibrations. The local auto parts store said they couldn’t even turn the brand new brakes because they were so out of round.

• UnknownCrashVehicle speed controlEngineUnknown or other

  UNKNOWN specific failed component. Immediately after fuel-injector-seal replacement by an independent repair shop, the engine was running rough. I drove less than 0.1 mile, parked about 10 minutes, then restarted the car. I heard an abnormal rapid ticking/grinding mechanical sound. With my foot on the brake, I shifted from Park into Reverse. The car immediately accelerated backward with what appeared to be full engine power. I did not intentionally depress the accelerator. I attempted to stop with the foot brake, but the car continued with substantial force, jumped curbs and struck a fence. I used the handbrake and shut off the engine; I also recall shifting into Neutral. Three tires and multiple wheels were damaged, the car sustained major body damage and was declared a total loss. No one was injured, but pedestrians, other vehicles and a nearby building were at risk. The incident was captured by a security camera. BMW of Palm Springs later found no reproducible mechanical cause. It noted a loose floor mat after the collision/towing and said it “may have caused the complaint,” but did not establish causation. I reported the incident directly to BMW North America. The representative suggested driver error and emphasized that the preceding repair was not performed by a BMW dealer. I was not offered an engineering investigation, follow-up path or case number. My insurer considered but declined an independent engineering examination. The vehicle was later disposed of, so the suspected component is no longer available for inspection. I later learned that this model uses a mechanical accelerator-cable throttle and that NHTSA has a prior complaint involving a 1997 540i reporting unintended acceleration from an accelerator-cable component that allegedly locked the throttle open. I am not asserting the same failure occurred in my vehicle. I am reporting this incident so NHTSA can compare it with other unintended-acceleration reports.
