2023 Nissan Leaf EV Brake Line Damage

Posted on by

Nissan has determined that certain 2023 model year Nissan Leaf EVs may have a damaged right hand brake tube that could result in a brake fluid leak.

Nissan first became aware of the potential problem in January 2023 when a Nissan technician noticed a 2023 Nissan Leaf EV being assembled with a damaged right hand brake tube assembly. Nissan collected the affected parts and began an investigation. The investigation included a parts audit of 975 brake assemblies which revealed twenty-five (25) damaged right hand brake tubes at the actuator connection bend. Nissan also conducted a yard audit of 395 vehicles and found five (5) with a scratched or damaged right hand brake tube. These parts were quarantined and the vehicles were put on a quality hold.

According to the defect report, an investigation with the supplier determined that the incorrect tooling was used to align the brake tube into the pipe bending jig. Because the brake tube was misaligned, the tooling clamped the pipe in the incorrect position and caused scratching, and in some cases deformation of the tube, at the actuator bend.

Nissan performed corrosion and stress tests on two (2) of the worst case condition parts to evaluate the effect of the damaged brake tube on brake performance over time. Nissan concluded that the brake performance could be degraded and could lead to extended stopping distances possibly without prior warning. Nissan decided to conduct a Voluntary Safety Recall to recall all potentially affected LEAF vehicles to inspect the right-hand brake tube and replace any damaged brake tube assemblies.

Owners receiving notices will be asked to return to their dealers to have the right-hand brake tube inspected for damage. If damage is found, the affected brake tube will be replaced. Nissan’s number for this recall is PC976 and the NHTSA campaign number is 23V-362.

Brake Pressure Switch Short May Cause Fire In Chevy Trucks

Posted on by

General Motors. LLC (GM) has decided that a problem exists in certain 2019-2023 Chevrolet 4500HD, 5500HD, and 6500HD medium-duty trucks. The brake pressure sensor assembly could leak brake fluid into the brake pressure switch and cause an electrical short circuit.

GM opened an investigation in August 2022 following reports of a vehicle fire on a 2019 Chevrolet Silverado medium-duty truck. As part of that investigation, GM reviewed field data potentially related to the problem and warranty returned brake pressure sensors.

While a series of tests failed to duplicate the condition, in January, a warranty-returned sensor and harness were identified as exhibiting signs of heat damage. This part was subjected to more detailed analysis, including X-ray scans and a chemistry laboratory analysis. The results from these analyses revealed the presence of brake fluid past the diaphragm seal, into the brake pressure switch, and through the actual wire harness into the pump’s fuse circuit. An inspection of the returned components also revealed delamination of the corrosion-inhibiting sealant, which allowed slow seepage of the brake fluid past the diaphragm seal.

According to the defect report, a zinc-nickel plating and sealant used to inhibit corrosion within the pressure sensor assembly may cause delamination of the sealant which results in small fragments of sealer underneath the diaphragm during assembly which allows brake fluid to slowly seep past the seal and into the pressure switch. The brake fluid may seep into the sensor’s electrical components and short the brake pressure switch and the associated fuse. If brake fluid shorts the brake pressure switch and the fuse, the circuit can generate enough heat and could result in a fire. An under-hood fire may occur when the vehicle is off and possibly unattended.

Owners are advised to park outside and away from structures until the recall repair is complete. Dealers will replace the master cylinder pressure sensor and inspect the wire harness. If the harness is damaged, it will be replaced as well. Interim letters notifying owners of the safety risk are expected to be mailed on May 29, 2023. Second letters will be mailed once the remedy is available. GM’s number for this recall is N222375270 and the NHTSA campaign number is 23V-266.

Owners of the affected vehicles will receive notices with instructions to return to their dealers to have the rear HVAC blower motor circuits at the left side B-pillar properly sealed. The recall is identified by GMC’s number N222386050 and the NHTSA campaign number is 23V-247.

Electrical Short In Battery Of Kia Soul EVs

Posted on by

Kia will be contacting owners of certain 2015-2019 Kia Soul EVs about a problem that could result in a short circuit in the high voltage battery pack and a potential vehicle fire.

Kia first became aware of the problem in May 2022 when they received reports of smoke from the battery vents located under the passenger seat on a 2017 Kia Soul EV. Kia records showed that the vehicle’s high-voltage battery had been previously replaced under warranty. In October Kia received a second report, involving a 2018 Soul EV. The customer reported the smell of smoke just before the vehicle stalled. Kia performed CT scans and a tear-down analysis for both vehicles but the results were inconclusive due to thermal damage and water intrusion from fire suppression.

As Kia investigated the first two reports they received a third customer complaint of popping noises and smoke coming from the cup holders of a 2018 Soul EV in Hawaii. Kia and the battery supplier inspect vehicle #3 and performed a tear down analysis which found the heat damage was limited to the battery case assembly. The preliminary investigation results were inconclusive and the battery was shipped to the manufacturer for further analysis.

According to the defect report, an electrical short between the anode and cathode of the battery cells can occur with the high-voltage battery pack assembly case. The cause of the electrical short circuit is unknown but believed to be caused by abnormally excessive precipitate within the battery cells.

Although the cause of the electrical short circuit is unknown, Kia has decided to recall all 2018-2019MY Soul EV vehicles equipped with an E400 battery and certain 2015-2017MY Soul EV vehicles that had the high voltage battery replaced under warranty with E400 battery.

Dealers will update the battery management system software with new software that will illuminate the EV warning light, limit charging capacity, and reduce vehicle power if an abnormal voltage is detected. If this occurs, the battery will be replaced. Owner notification letters are expected to be mailed on May 26, 2023. Kia’s number for this recall is SC267 and the NHTSA campaign number is 23V-218.

There have been three (3) thermal incidents limited to the battery case assembly with no injuries, no crashes, and no fatalities.

2023 Genesis G90 Abnormal Pretensioner Deployment

Posted on by

Hyundai Motor America (Hyundai) will be contacting the owners of certain 2023 Genesis G90 luxury sedans because of a defect affecting the seat belt pretensioners in their vehicles. The problem could result in an increased chance of injury to vehicle occupants.

In October 2022, Hyundai received information pertaining to an investigation into allegations of abnormal seat belt pretensioner deployments in vehicles associated with recalls 21V-796, 22V-069, 22V-123, 22V-218, 22V-354, and 22V-458. Recall 22V-816 was initiated as Hyundai continued to evaluate vehicles equipped with the same Samsong pretensioners that had not yet been recalled..

In January, during the continued analysis of the airbag control unit (ACU) crash pulse data recovered from a North Carolina incident, they found that the micro gas generator (MGG) separated despite having a lower pretensioner “time-to-fire”. This was the problem that was previously thought to be the contributor to over-pressurization of the pretensioner pipe. Because of this information, the North America Safety Office (NASO) decided to conduct a safety recall 012G (23V-094) of Genesis G80, GV60, GV70, and GV80 vehicles equipped with pretensioners without a vent valve. Recall 012G (23V-094) supersedes Recall 009G, obsoleting all affected population(s) of Recall 211/009G (21V-796).

In March, during the review of details surrounding Hyundai’s assessment of the open investigation into the recent recalls, Hyundai noted that the recent recalls address all U.S. vehicles equipped with the subject Samsong seat belt pretensioner excluding Genesis G90 vehicles. The G90 contains the same seat belt pretensioners but because it is installed facing outward and away from occupants, fragments entering the cabin area and injuring occupants are significantly less likely to happen. Based on this information, the NASO decided to conduct a safety recall (013G) of Genesis G90 vehicles equipped with pretensioners without a vent valve. NHTSA campaign number 23V-210.

According to the defect report, the subject vehicles are equipped with frontal/rear pyrotechnic-type seat belt pretensioners that could deploy abnormally in certain crash conditions. The problem is due to the over-pressurization of the pretensioner pipe. Depending on specific vehicle characteristics such as pretensioner load limiter specification, the airbag control unit logic, crash duration/severity, and micro-gas generator orientation, occupants could experience an increased risk of injury.

Owners of the affected vehicles will be notified with instructions to bring their vehicles to a Hyundai dealer to have the seat belt pretensioner’s micro gas generator and delivery pipe secured with a cap to prevent potential abnormal deployment.
