Hello so I notice 3 weeks ago my headlights keep cutting off and on then a week later my radio stopped working, The floor of the driver side is always wet after it rains. I noticed one day the rain started dripping on my feet when I drive after a big rain fall, I believe the car is not sealed properly and now water is coming out from the airbag signs in my vehicle and the car starting to smell like mildew. I think water is sitting in certain parts of my vehicle. I'm not sure what to do.

Defect investigations
Outboard Front Seat Belt Anchor Cable Failure
On August 31, 2020, the Office of Defects Investigations (ODI) opened Engineering Analysis (EA) EA20002, as an upgrade of Recall Query (RQ) RQ19003. This investigation, related to recall 14V‑266, was opened to investigate instances of detachment of the flexible steel seat belt anchor cable attached to the outboard side of the front seats in vehicles manufactured by General Motors (GM). The subject vehicles included model year (MY) 2009 through 2014 GMC Acadia, Buick Enclave, and Chevrolet Traverse SUVs as well as MY 2009 through 2010 Saturn Outlook SUVs. These vehicles were previously repaired for this defect under recall 14V‑266. The subject vehicle population is approximately 1.3 million vehicles. Special Coverage N192219480, issued in June 2019, addressed the subject defect in vehicles that previously received the recall remedy repair for subject recall 14V‑266. The Special Coverage allows for component replacement for 12 years or 180,000 miles from the initial sale date, whichever comes first. Special Coverage N192219480 instructed service technicians to inspect the driverâs seat belt anchor cable for any damage to the protective sleeve and if damage was observed, the cable was replaced with a new sleeve as well as a new closeout piece that relocated the cable to mitigate the subject condition. In view of the Special Coverage conducted by General Motors, the high detectability of the subject failure, and the low rate of occurrence, this Engineering Analysis is closed. The closing of this investigation does not constitute a finding by the federal safety agency that a safety-related defect does not exist. The Agency reserves the right to take additional action if warranted by future circumstances. To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to Please see the attached document âEA20-002 Detailed Closing Summaryâ for more a detailed closing resume summary.

Seat Belt Anchor Cable Failure
On May 19, 2014, General Motors LLC (GM) notified the Office of Defects Investigation (ODI) that it would conduct Safety Recall 14V266 to address fatigue and separation of the flexible steel cable that connects the front outboard seat belts to the seat-mounted belt pre-tensioner in 1.4 million model year (MY) 2009-2010 Saturn Outlook, 2009-2014 Buick Enclave, GMC Acadia and Chevrolet Traverse (Lambda Platform) vehicles.The remedy was to inspect for signs of damage and replace pre-tensioner anchor cables as needed. Re-work was conducted to relocate the pre-tensioner anchor cable out of the occupant entry path. ODI has subsequently received four (4) Vehicle Owners Questionnaires (VOQ) reporting anchor cable separations with no apparent warning in covered vehicles after the Recall 14V266 remedy had been applied.ODI opened RQ19-003 to assess the effectiveness of the actions GM took in Recall 14V266 and review the full warranty and complaint data related to seat belt anchor cable separations and replacements. ODI continues to receive occasional cable failure complaints both for the subject vehicles and other GM models and model years that have also been previously recalled addressing this condition.Although the cable separation complaint rate is very low, over the past three years ODI has received two (2) additional VOQ?s citing belt cable separations for Lambda platform vehicles outside the scope of recall 14V266, (11217092, 11118075) and complaints for other GM models covered in a number of similar Safety Recalls:* 15V269, 2011-12 Chevrolet Malibu (11181115, 11288168); * 16V209, 2014-15 Silverado 1500, Sierra 1500 (11254364, 10935183, 10953851, 11025376, 11282043, 11288701, 11309884); and * 16V518 2014-16 Caprice Police Pursuit, SS (10905644, 10990669, 11340893).ODI's review of GM's data confirms the low potential failure rate for the vehicles covered by recall 14V266. However, ODI believes that complainants may not recognize accumulating cable fatigue damage from the visual cues available in routine vehicle use.ODI is upgrading RQ19-003 to an Engineering Analysis to more closely assess seat belt conditions and strength levels in the field. This work will include the collection of seat belt samples from a wider range of recalled and peer vehicles for detailed analysis and testing.The ODI reports (VOQs) associated with this RQ19-003 can be viewed at under the following reference numbers: 11144704, 11076704, 11185619, 11151922, 11164011, 10967518, 11113486, 11115648

service battery charging station error code keeps popping up
Daytime Running light bulb and housing failure. Some 2012 Acadia models recalled under now expired recall for bulbs and deformation of surrounding housing. Apparently the above recall was excluded from this recall and should have been included. Both DRL on this vehicle have failed and surrounding housing has been damaged . Subsequently replacing just bulbs is not possible. The housing melted on the bulb. Photo is available on request. This failure should be considered a fire hazard. GM customer service center stated to me that this vehicle was not included in recall after VIN search. Some 2012 Acadias were in fact included , this one was not. And should have been since the failure occurred as stated in the original recall.
