2012 Volkswagen Tiguan Electrical Problems

Your sunroof is leaking water into the car's interior, causing widespread electrical damage, mold growth, and rust that has damaged the roof lining and carpets. The water intrusion has disabled critical safety features including your airbags and horn, and has caused the clock spring (part of the steering wheel assembly) to fail. You've had to spend thousands on electrical repairs to diagnose the problem, and water accumulated in hidden areas has frozen and prevented you from driving safely. Fixing this will likely require sealing or replacing the sunroof assembly, drying out the interior completely, repairing electrical components, and replacing damaged safety system parts.

Your car's panoramic roof drains weren't working properly, causing water to leak inside the vehicle. On September 18, 2023, your daughter was in an accident when the car shut off unexpectedly and the brakes wouldn't work—the airbags also failed to deploy. An electrical short has been confirmed as the cause of these failures.

Your instrument panel display started turning on and off while you were driving. Since then, you've noticed multiple electrical problems including interior and exterior lights not working properly, the door open warning light malfunctioning, the infotainment system not functioning, and several unknown warning lights appearing on the dashboard. The vehicle hasn't been repaired or diagnosed by a mechanic yet. Fixing this will likely require a diagnostic scan to identify which electrical circuits or components are failing, followed by repairs to the wiring, connections, or faulty modules.

WATER IS LEAKING FROM THE SUNROOM ON THE PASSENGER FRONT SIDE WHEN IT RAINS. I AM CONCERNED BECAUSE IT IS SOAKING THE AREA AROUND THE ELECTRONICS, AND HAS FLOODED THE FOOTWELLS OF THE FRONT AND REAR PASSENGER SIDE OF THE VEHICLE. IN ADDITION, NOW THE RIGHT SIDE OF THE HVAC SYSTEM IS NOT FUNCTIONING PROPERLY AND I CANNOT DE-FOG THE ENTIRE RIGHT SIDE OF THE WINDSHIELD WHILE DRIVING. THERE IS ALSO SIGNIFICANT MOLD BUILD UP FROM THE DAMP AREAS, AND IT DOESN'T SEEM LIKE A GOOD IDEA TO BREATHE THAT IN. WATER DRIPS AND SOAKS THE RIGHT SIDE OF THE VEHICLE WHEN STATIONARY OR IN MOTION IN THE RAIN. LEAK HAS BEEN GETTING PROGRESSIVELY WORSE OVER THE LAST SEVERAL MONTHS.

WE ALREADY HAD A PRIOR COMPLAINT IN ABOUT THE MANUFACTURERS DEFECT OF THE DRAINAGE SYSTEM IN THIS VEHICLE ODI# 412775589 REF# 238025. WE SAID IT WAS AFFECTING THE ELECTRICAL COMPONENTS IN THE CAR. TODAY WE HAD TO REPLACE THE IGNITION STARTER BUTTON DUE TO THE CONDENSATION. WE HAVE ALSO CONTACTED VOLKSWAGON PRIOR TO THIS, BUT THEY JUST IGNORE THE ISSUE.

I'VE ONLY OWNED THE VW TIGUAN 2012 FOR 6 MONTHS, JANUARY 2020 AND THE VEHICLE ENGINE SHUTS OFF, ALL POWER LOST AND HAS TO BE RESTARTED. THIS HAS HAPPENED MORE THAN 8 TIMES IN THE PAST 6 MONTHS, 2 TIMES IN THE PAST WEEK, IT SHUT OFF WHILE DRIVING ON THE HIGHWAY AND YESTERDAY JULY 20,2020 WHILE DRIVING THROUGH AN INTERSECTION.

MY CAR ONLY HAS 50K MILES ON IT. THE COOLANT LIGHT COMES ON EVERY MONTH OR SO. WHEN I CHECK THE COOLANT THE LEVER IS SEVERELY LOW. THERE MUST BE A PROBLEM WITH A DEFECTIVE PART ON THE VW TIGUAN WHY THIS IS HAPPENING. CAN SOMEONE EXPLAIN THE ISSUE HERE? THANKS. *TR

TL* THE CONTACT OWNS A 2012 VOLKSWAGEN TIGUAN. THE CONTACT STATED THAT THE PANORAMIC SUN ROOF WAS DEFECTIVE AND CAUSED WATER TO LEAK INTO THE VEHICLE. AS A RESULT, CERTAIN ELECTRICAL COMPONENTS WERE AFFECTED, SUCH AS THE GEAR LIGHTS AND VANITY LIGHTS. ALSO, THE PUSH START ENGINE BUTTON WAS DEFECTIVE. THE CONTACT HAD TO PUSH THE BUTTON SEVERAL TIMES BEFORE THE VEHICLE WOULD START. THE MANUFACTURER WAS NOTIFIED OF THE FAILURES AND PROVIDED CASE NUMBER: [XXX]. THE VEHICLE HAD NOT BEEN REPAIRED. THE FAILURE MILEAGE WAS LESS THAN 50,000. *DT *TR CONSUMER STATED CAR IS DEVELOPING MOLD INSIDE WHERE IT IS LEAKING.*DT CONSUMER ALSO STATED AIRBAG GOES ON AND OFF, BUT FOR NOW DUE TO CONDENSATION IT IS STAYING ON.*DT ('PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).')*JB*JB THE CONTACT STATED THE VEHICLE SHUT OFF WHILE DRIVING AND WOULDNT STOP, WHICH RESULTED IN AN ACCIDENT.

ON THIS JULY 4TH HOLIDAY, THE ENGINE OF OUR 2012 TIGUAN (LESS THAN 52K MILES, FIRST OWNER) BEGAN TO STUTTER ON THE FREEWAY AND THE CHECK ENGINE LIGHT STARTED TO FLASH. THIS OCCURRED AT 70 MPH IN THE FAST LANE OF A 6-LANE FREEWAY AT A MERGE (I-85 AT THE MERGE WITH GA-400 SOUTHBOUND). EVEN AS THE VEHICLE DRAMATICALLY LOST SPEED, WE WERE FORTUNATE ENOUGH TO BE ABLE TO PULL OVER INTO THE SLOWER LANES SAFELY. TRAFFIC WAS LIGHT AND FAST THAT AFTERNOON. I PROMPTLY SCHEDULED AN APPOINTMENT WITH THE VW DEALERSHIP (NALLEY VW OF ROSWELL) FOR THE FOLLOWING MORNING, ANXIOUS TO FIX THE PROBLEM. THE SERVICE TECHNICIAN RAN DIAGNOSTICS ON THE VEHICLE AND ADVISED ME THAT I NEEDED TO REPLACE ALL FOUR IGNITION COILS AND SPARK PLUGS. I WAS INFORMED THAT CYLINDER 2 WAS MISFIRING. I WAS SURPRISED TO FIND THAT COILS WOULD FAIL AT AS LOW A MILEAGE AND HAD CREATED AN UNSAFE SITUATION FOR US. IT APPEARS THERE ARE NUMEROUS INSTANCES OF COIL FAILURE FOR THIS VEHICLE. I CONTACTED AND INFORMED VW OF THE ISSUE. THEY DECLINED TO TAKE ANY ACTION TO COMPENSATE ME FOR SUCH PREMATURE COMPONENT FAILURE, LET ALONE ACKNOWLEDGE THAT THE FAILURE MADE FOR AN UNSAFE CONDITION ON THE ROAD. THE VW SERVICE CENTER REPLACED ALL FOUR COILS AND SPARK PLUGS THE FOLLOWING DAY, CORRECTING THE PROBLEM.

CLOCK SPRING FAILURE IN MOTION WHILE TURNING ON A CITY STREET WITH A LITTLE OVER 40K MILES ON VEHICLE. THIS VIN NUMBER DID NOT APPEAR ON 15V-483 RECALL. RECOMMEND INCLUSION OF THIS COMPLAINT ON THE RQ 17-009 INVESTIGATION TO WIDEN THE RECALLED VIN'S. REPAIR DONE BY OKC VOLKSWAGEN AT A COST OF $600

I WAS DRIVING AND THE CAR BEGAN TO STALL AND VIBRATE. I HAD TO PULL OVER AND TOOK THE CAR IN AND THE REPORTED THAT THE IGNITION COIL WAS BAD.

TL* THE CONTACT OWNS A 2012 VOLKSWAGEN TIGUAN. WHILE SLOWING DOWN TO MAKE A RIGHT TURN INTO A FUEL STATION, THE VEHICLE STALLED WITHOUT WARNING. IN ADDITION, AFTER PLACING FUEL IN THE FUEL TANK, THE VEHICLE FAILED TO START. THE CONTACT ALSO STATED THAT THE ENGINE WARNING INDICATOR ILLUMINATED PRIOR TO THE VEHICLE STALLING. THE VEHICLE WAS TOWED TO A DEALER WHERE IT WAS DIAGNOSED THAT THE TIMING BELT SLIPPED AND CAME OUT OF TIMING. THE FAILURE CAUSED ALL THE PISTONS TO FIRE AT ONCE AND DESTROYED THE ENGINE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 107,000. UPDATED 07/18/17*LJ *CN

WIPERS SUDDENLY STOPPED MOVING. THIS COULD BE A SERIOUS SAFETY ISSUE. THE DEALER HAD TO REPLACE THE J519 POWER CONTROL UNIT IN ORDER TO FIX THIS ISSUE. *TR

WHILE DRIVING ON A HIGHWAY AT APPROXIMATELY 35MPH THE VEHICLE SHUT DOWN. I TRIED TO RE-START THE ENGINE AND IT DID NOT START. THE VEHICLE CAME TO FULL STOP. IT TOOK A WHILE TO RE-START THE ENGINE. THE FIRST INCIDENT WAS REPAIRED BY A VW DEALER, BUT I NEVER GOT A CLEAR EXPLANATION OF WHAT HAPPENED. THE SECOND INCIDENT HAPPENED LAST SUNDAY ON A HIGH TRAFFIC LOCAL ROAD AT ABOUT 45 MPH. THE VEHICLE SHUT DOWN AND AGAIN CAME TO A FULL STOP. IT WILL NOT RE-START.

WHILE DRIVING ON HIGHWAY GOING APPROXIMATELY 50 MPH IN A MERGING LANE, CAR WOULD NOT ACCELERATE ANY FURTHER. CARS WERE SPEEDING BY AND I COULD NOT ACCELERATE. EPC LIGHT CAME ON. HAD TO GET OFF HIGHWAY AND HAVE CAR TOWED TO DEALERSHIP. *TR

SEVERAL TIMES WHILE DRIVING MY SUV MANY FAILURE INDICATOR LIGHTS INDICATING EPC FAILURE, TIRE MONITORING SYSTEM FAILURE, LICENSE PLATE LIGHT NOT WORKING, LEFT TURN SIGNAL NOT WORKING, BRAKES LIGHTS DO NOT LIGHT UP, ESC NOT FUNCTIONING. TRUNK ALSO WILL NOT UNLOCK. IT SEEMED LIKE EVERY SYSTEM WARNING LIGHT THIS CAR HAS CAME ON SHOWING SYSTEM FAILURES. EVERYTIME THIS HAS HAPPENED MY CAR LOSES POWER AND BARELY WANTS TO MOVE OR STALLS ALL TOGETHER HAVING THE AUTOMOBILES BEHIND ME ALMOST REAR END MY SUV. THIS SUV WITH THESE PROBLEMS IS A ACCIDENT WAITING TO HAPPEN & SOMEONE IF NOT ME DRIVING THESE SUV'S WILL GET INTO AN ACCIDENT IF VW DOESN'T FIND THE RIGHT PROBLEM TO CORRECT THIS SAFETY ISSUE SO MANY OWNERS ARE HAVING THE SAME ELECTRICAL PROBLEMS I READ ONLINE PLUS THE ONES WHO HAVE FILED A COMPLAINT ALREADY. *TR
