CERTAIN PRO-A MOTORS CORNER LAMPS, TURN SIGNALS, AND HEADLIGHTS SOLD AS REPLACEMENT LAMPS FOR USE ON CERTAIN PASSENGER VEHICLES LISTED ABOVE. SOME COMBINATION LAMPS THAT ARE NOT EQUIPPED WITH AMBER SIDE REFLECTORS FAIL TO CONFORM TO FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 108, LAMPS, REFLECTIVE DEVICES, AND ASSOCIATED EQUIPMENT.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE REAR AXLE DIFFERENTIAL MAY CONTAIN RING GEAR BOLTS THAT WERE INCORRECTLY TORQUED DURING ASSEMBLY. THE BOLT OR BOLTS COULD LOOSEN LEADING TO NOISE FROM THE DIFFERENTIAL.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE NUT THAT SECURES THE MAIN POSITIVE CABLE TO THE POSITIVE BATTERY TERMINAL CLAMP WAS NOT TIGHTENED PROPERLY, ALLOWING THE CABLE TO LOOSEN OVER TIME. IF THIS OCCURRED, THE CABLE COULD ULTIMATELY LOOSEN TO THE POINT WHERE ELECTRICAL CONTINUITY COULD BE INTERRUPTED.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“VERY WELL KNOWN FAILURE, JUST SEARCH FOR "BMW Z3 SUBFRAME FAILURE". IT IS A DESIGN FLAW BY BMW THAT AFFECTS A LOT OF Z3'S THROUGH ALL MODEL YEARS. MINE STARTED TO POP ONE WELD AT 88K MILES. IT CAN CAUSE THE REAR ALIGNMENT TO BE OFF, IN WORST CASE THE TRUNK FLOOR IS TORN OUT AND THE DIFFERENTIAL FALLS TO THE GROUND. CLUNKING FROM THE BACK WHILE SHIFTING IN THE FIRST TWO GEARS IS ONE INDICATOR THIS DAMAGE IS NOT FAR AWAY. THIS IS ONE FORUM THREAD THAT DESCRIBES THE ISSUE WELL: HTTPS://WWW.BIMMERFORUMS.COM/FORUM/SHOWTHREAD.PHP?1979601-SUBFRAME-TRUNK-FLOOR-DIFFERENTIAL-MOUNT-FAILURE”
“Hello, NHTSA released a recall warning for BMWs made from 2000 to 2006, regarding Takata airbags. "The risk to vehicle occupants is dire," it said. My 1999 BMW Z3 was made one year before this, and is not included in the recall. I have been trying to determine whether my '99 BMW has Takata airbags as well, thus far with no success. As of today, BMW will only tell me that there are no outstanding recalls for my car - they have not been willing to tell me what type of airbags they originally installed in it. Do your records indicate what type of airbags I have?”
“TL* THE CONTACT OWNS A 1999 BMW Z3. AFTER THE VEHICLE WAS STARTED AND PLACED INTO REVERSE, A CLANKING SOUND EMERGED FROM THE REAR END WITHOUT WARNING. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED.
