Volvo XC40 BEV Acceleration Problems

Posted on by

Some 2021-2022 Volvo XC40 BEV vehicles may experience accelerator issues because of a corrupt acceleration signal caused by corrosion within the accelerator pedal sensor (APS).

Volvo became aware of the problem in the first quarter of 2022 when they started receiving customer reports of different issues with accelerator pedal behavior. The problem was presented to the Critical Concern Management Team (CCMT) and, following an investigation and risk assessment, a recall was initiated.

According to the defect report, water entering the APS wire harness could cause corrosion within the accelerator pedal’s internal circuits. If this happens signals from the pedal could become corrupt.
Depending on which signal corrupts, the faults may differ. Drivers may experience unintended acceleration or no acceleration, loss of drive power, and/or a no-start condition. These vehicles do have a built-in safety logic that will reduce the acceleration when a corrupt signal is received. The vehicle is still controllable, and the driver is always able to stop the vehicle using the brake pedal.

Vehicles produced between 9-08-2020 and 8-13-2021 had an older style harness. Since then, there was a change in the cable harness supplier. The last vehicle produced with the older style harness was produced on 8-13-2021.

Owners will be asked to return to their dealers to have the accelerator harness and sensors inspected for corrosion and repaired as necessary. A cable splice will be installed to prevent water intrusion and, as necessary, the connector terminal and APS could be replaced. Volvo’s number for this recall is R10170 and the NHTSA campaign number is 22V-288.

2018 BMW 540D xDrive
Coolant Leak Could Result In Fire

Posted on by

A small number of 2018 BMW 540d xDrive vehicles, equipped with Exhaust Gas Recirculation (EGR) modules could experience an internal glycol coolant leak that may result in an engine fire.

BMW first became aware of the problem in October 2018 when they opened an investigation into reports of certain BMW vehicles experiencing engine fires. What they found was; that these vehicles were equipped with an Exhaust Gas Recirculation (EGR) module with an integrated cooler that could leak coolant internally. The coolant mixed with diesel engine soot, combined with the high EGR temperatures could result in smoldering, fire, and a melted intake manifold.

During vehicle operation, the driver may be alerted there is a problem through:

  • A warning symbol in the instrument cluster displaying a loss of engine coolant.
  • A reduction in engine power.
  • An unpleasant exhaust odor.
  • Unusual noise from the engine compartment.
  • Smoke from the engine compartment.

NHTSA campaign number 18V-755 – BMW recalled 44,368 vehicles.

This recall campaign affected certain 2013-2018 BMW vehicles with the N47T and N57T diesel engines that were produced from September 12, 2012, to June 29, 2017.

The vehicles affected include:

2013-2018 328d
2013-2018 328d xDrive
2014-2018 328d Sports Wagon
2014-2018 328d xDrive Sports Wagon
2014-2016 535d
2014-2016 535d xDrive
2015 740Ld xDrive
2015-2017 X3 xDrive28d SAV
2014-2017 X5 xDrive35d SAV

NHTSA campaign number 21V-907 – BMW recalled 50,404 vehicles.

After continued field monitoring and review of field data, BMW determined that the EGR cooler may not be sufficiently durable to last the lifetime of the vehicle. They decided to issue a recall that would replace the EGR module on all potentially affected vehicles, with an improved cooler design. The intake manifold was inspected and replaced as necessary, and the EGR pipe connecting the cooler to the manifold was cleaned.

NHTSA campaign number 22V-614 – BMW is recalling 298 vehicles.

The vehicles subject to this recall have a different design and manufacturer of the EGR cooler than the vehicles previously recalled. After further monitoring and review of field data, it was found that the specific EGR cooler for certain 2018 BMW 540d xDrive vehicles may not be robust to last the vehicle’s lifetime. BMW has decided to perform a recall for these vehicles as well.

Owners receiving notices will be asked to return to their BMW dealer to have the EGR module replaced and the intake manifold inspected and replaced as necessary.

Cadillac, Chevy & GMC Seat Belt Buckle Assembled With Improper Rivets

Posted on by

General Motors (GM) will be contacting the owners of certain 2021-2022 Cadillac, Chevrolet, and GMC SUVs equipped with third-row seating. These vehicles may have been manufactured with an improperly formed mounting bracket rivet that may not restrain an occupant during an accident.

The vehicles affected by this problem include:

2021-2022 Cadillac Escalade
2021-2022 Cadillac Escalade ESV
2021-2022 Chevrolet Suburban
2021-2022 Chevrolet Tahoe
2021-2022 GMC Yukon
2021-2022 GMC Yukon XL

In May 2022, a GM dealership received a customer complaint about the separation of the third row seat belt assemblies in their 2021 Chevrolet Suburban. The problem was submitted to GM’s Speak Up For Safety program and a formal investigation was opened. During this investigation, another seven additional field reports were found that could be related to this condition. Further investigation into the problem determined that operators at the seat belt buckle assembly supplier’s manufacturing plant may have not properly followed manufacturing processes and as a result, may have missed the rivet forming operation. In July, GM’s investigator met with the seat belt buckle assembly supplier to determine the scope of potentially affected parts. On August 4, 2022, GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a safety recall.

According to the defect report, the rivet that retains the buckle to the mounting bracket in the left and/or right side third-row seat belt buckle assembly may not have been properly formed during the manufacturing process. If the assembly is not properly riveted, it will not restrain occupants during an accident and could result in increased injuries.

Owners receiving recall notices will be asked to return to their GM dealer to have the rivet head formation on both the left and right side third-row seat belt buckle assemblies inspected and replace seat belt buckle assemblies, as necessary. GM’s number for this recall is N222372380 and the NHTSA campaign number is 22V-617.

Chevy Bolt Battery Problem Update

Posted on by

General Motors is still rolling out new batteries for the troubled Chevy Bolt electric vehicle, albeit very slowly. We are hearing from clients and potential clients that dealerships are putting them on “wait lists” for the new battery but are not hearing again from the dealership. The dealerships give the owner no times table for getting their new battery as well. Obviously, this is very frustrating for consumers who are tired of figuring out ways to safely charge their EV. To date, we have only heard of the new batteries actually being installed in the 2017 – 2019 year models, but not for any 2020-2021 models. The good news is that once the battery has been installed, consumers seem to be happy with the new battery giving them a longer range than the original. More importantly, we have not heard of any problems associated with the new battery. This is good news for consumers.

With that said, we are still accepting Chevy Bolt cases, regardless of whether the new battery has been installed, and we continue to achieve favorable settlements with General Motors. Many of our settlements are for cash, allowing the consumer to receive compensation while being allowed to keep the vehicle.

Please call us at 1-888-395-3666 for more details about this problem.

Chevrolet Bolt EV

Here is a summary of the defect.
General Motors recalled all of their Chevrolet Bolt EVs because there is a manufacturing defect affecting the battery cell. The problem is aggravated when the battery is charged to a full or nearly full state after it has been substantially depleted. The battery could overheat and catch fire, causing damage to the vehicle and structures around it. As a temporary solution, GM asked owners to reprogram their hybrid propulsion control module to limit a full charge.

The safety recall from the NHTSA states the following:
As an interim remedy, dealers will reprogram the hybrid propulsion control module to limit full charge to 90%. Until this interim is completed, customers should enable either “Hilltop Reserve” (for 2017-2018 model year vehicles) or “Target Charge Level” (for 2019 model year vehicles) using their vehicle’s infotainment center. These two features will limit the vehicle’s state of charge to 90% until the HPCM2 software re-calibration is applied. If customers are unable to successfully make these changes or do not feel comfortable making these changes, they will be advised to not park their car in their garage or carport until after they have visited their dealer.

Insufficient Welds In Ford Escape And Lincoln Corsair High Voltage Batteries

Posted on by

The high voltage batteries in certain 2020 Ford Escape and 2021 Lincoln Corsair vehicles may have been manufactured with insufficient welds that could fail and cause a loss of drive power. These vehicles are equipped with 2.5L hybrid powertrains.

Ford’s Critical Concern Review Group first became aware of the problem in February 2022 when they were informed, by the supplier, that there was an issue with the weld penetration on the bus bars of certain high voltage batteries. A review of the manufacturers’ records showed that the suspect cause of the problem was damage to the laser cooling line caused by maintenance of the laser air knife. The damage to the laser cooling line resulted in an out-of-control weld process and insufficient welds. The suspect time period was between June 6, 2020, and June 12, 2020.

According to the safety report, insufficient weld penetration between the bus bar and cell terminal could result in a loss of electrical contact at the bus-bar weld joint inside the high voltage battery. Loss of electrical contact will result in a loss of motive power and an increased risk of an accident.

The vehicle warning display will illuminate a “Stop Safely Now” message, a wrench lamp, and an audible alert when the vehicle loses motive power.

Owners receiving notices will be asked to take their vehicle to their Ford or Lincoln dealer to have the High Voltage Battery replaced. The new High Voltage Battery LX68-10B759-R will have a bus bar that has proper weld penetration. The supplier repaired a damaged coolant line on June 27, 2020. High voltage batteries produced after June 27, 2020 were produced with sufficient bus bar weld penetration. Ford’s number for this recall is 22S33 and the NHTSA campaign number is 22V-331.

Ford F-150 Transmission Shifts Into Neutral While Driving

Posted on by

Some 2021 Ford F-150 trucks could unexpectedly shift into neutral while driving. The unexpected loss of engine power could increase the chance of an accident.

In February 2022, an issue was brought to Ford’s Critical Concern Review Group (CCRG) about certain 2021 F-150 vehicles equipped with 3.5L GTDI, 2.7L, and 5.0L engines, along with the 10R80 transmission. These trucks were experiencing an increase in Transmission Fluid Pressure along with a Transmission Fluid Pressure Low Diagnostic Trouble Code (DTC) of P0868. This DTC would falsely activate and cause the transmission to shift into a neutral state while the truck was driven. Once the false activation occurs, the vehicle will coast to a stop and the electronic shifter will attempt to engage Park. Once the vehicle comes to a complete stop, the electronic shifter will automatically shift into Park.

According to the engineering investigation, one of the power-train diagnostic logic software branches was turned on in error when these vehicles were produced. Under certain conditions, this diagnostic logic could inadvertently activate the pump gear failure detection logic even though the hardware is still functioning properly. When this happens, the transmission on-board diagnostics will set the DTC P0868, turn on a Wrench Light telltale, and the vehicle’s transmission will shift into a neutral state. As the vehicle slows to a speed below 2 mph/3kph, the electronic shifter will attempt to engage the Park function and will automatically shift into Park when the vehicle comes to a complete stop. The transmission function can be restored by a key-off/key-on cycle.

Between October 2021 and February 2022 there have been 28 warranty claims and one Customer Contact Center report to Ford that potentially related to this concern.

Dealers will correct the problem by updating the Power-train Control Module (PCM) software. Ford’s number for this recall is 22S15 and the NHTSA campaign number is 22V-188.

Unreliable HV Battery Connection May Cause 2021 VW ID.4 To Stall & Not Start

Posted on by

Volkswagen Group of America, Inc. (VW) will be asking a small number of 2021 VW ID.4 electric crossover SUV owners, to return to their dealerships because of a problem affecting the solder connections inside the HV battery of their vehicles. This defect could result in a stall and may increase the risk of an accident. A fix for this problem is still under development by the manufacturer.

VW became aware of the defect in January 2021 when the first known field case occurred outside the U.S. VW quality and safety departments began to monitor the field reports for the nature and frequency of the non-starting condition and found reports of similar problems in other brand vehicles using the same or similar battery systems. During a multi-brand clearing committee meeting, impacted brands shared information on the potential stall while driving cases and decided to conduct a recall. Volkswagen will be conducting a recall on 351, 2021 VW ID.4 vehicles in the U.S. that contain the potentially affected parts.

According to the defect report, a manufacturing problem with the high voltage (HV) battery may have caused incorrect soldering on specific points of the flexible printed circuit assembly (FPCA). The amount of solder contact points of the FPCA is not sufficient and the thickness of the solder layer is out of tolerance parameters. The result is an unreliable connection inside the HV battery that could lead to a breakdown or stalling while driving. If this issue is present in the vehicle, the driver will be alerted by a high voltage system warning message in the instrument panel.

Owner notification letters about the defect are expected to be mailed by May 13, 2022. Volkswagen’s number for this recall is 9302 and the NHTSA campaign number is 22V-1562.
