General Motors (GM) has decided that a safety defect affecting suspension exists in certain 2022 Cadillac XT5, 2022 Cadillac XT6, and 2022 GMC Acadia vehicles. Owners will be receiving notices with instructions to return to their Cadillac or GMC dealer to have the suspension in their vehicle inspected and repaired as necessary.
GM became aware of the problem in March 2022, after a quality engineer at one of GM’s assembly plants identified a Cadillac XT6 that was missing a toe link to a knuckle bolt in the vehicle’s left side rear suspension. The manufacturing records showed that the bolt had been fully tightened, but further investigation found that the supplier’s error-proofing equipment had been improperly configured following a change in the assembly process. As a result, the tool operator could have failed to fully tighten the bolt without the error-proofing equipment detecting it.
According to the defect report, after an assembly process was moved to a new area, error-proofing equipment was not initially set up properly. This allowed a window where the operator may miss tightening certain fasteners without the failure being flagged. The affected toe links may be loose or become separated, resulting in misalignment of the left-rear wheel and increasing the risk of a crash
GM investigated the potentially affected population and inspected 271 suspensions that had been contained at the plant, with six more instances of loose fasteners identified. Although GM have not received any claims or complaints related to the subject condition and they are not aware of any associated accidents or injuries but have decided to conduct a safety recall.
Dealers will inspect the left-rear suspension and replace the fastener if it is loose or missing. GM’s number for this recall is N222364330 and the NHTSA campaign number is 22V-427. Approximately 736 vehicles may be affected.
General Motors (GM) will be asking a small number of 2022 Chevrolet Heavy Duty (HD) truck owners to return to their GM dealership for a problem affecting the brakes in their vehicles. The primary hydraulic brake line assembly may have not been tightened to manufacturer specifications and could loosen and leak.
The vehicles affected by this problem include:
|2022 Chevrolet 4500HD
|2022 Chevrolet 5500HD
|2022 Chevrolet 6500HD
In April 2022, during assembly end of the line testing, GM discovered that several of their Chevrolet HD trucks were experiencing a soft brake pedal feel and/or extended stopping distances. Navistar, the manufacturer of these vehicles informed GM that they intended to file a safety recall for this condition, and in May, GM’s Safety and Field Action Decision Authority (SFADA) decided to conduct a safety recall on the GM badged vehicles produced in the same suspect production period as the recalled Navistar vehicles. GM is not aware of any relevant field reports or crashes related to this problem.
According to the defect report, an investigation by the manufacturer of these vehicles found that the pressure sensor fitting of the primary hydraulic brake line assembly may not have been tightened to the correct manufacturer torque specification. If the brake line assembly loosens and brake fluid is lost, drivers may experience a soft or low brake pedal feel, extended stopping distances and the brake warning light may illuminate. Owners may also notice brake fluid on the ground or in the engine compartment.
Owners receiving notices will be asked to return to their dealers to have the brake pressure switch tightened to specification. They will also bleed the brake system and top off the brake fluid.
GM’s number for this recall is N222368230 and the NHTSA campaign number is 22V-364.
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.
Automobile manufacturers Hyundai and Kia will be asking owners of certain 2022 Hyundai Ioniq 5 and 2022 Kia EV6 vehicles, to return to their dealerships for a problem affecting the parking brake mechanism. A software error in the Shifter Control Unit (SCU) may disengage the parking mechanism and allow the vehicle to roll away.
Hyundai and Kia first became aware of the problem in April/May 2022 after reports about warranty claims involving some Ioniq 5 and EV6 vehicles in Korea. The vehicles allegedly unexpectedly rolled away after being parked on an incline with the ignition off. Further investigation into the incidents found voltage fluctuations in the electrical system that could affect the command signal from the Shifter Control Unit (SCU) to the parking actuator. The result would be a momentary disengagement of the parking pawl.
According to the safety report, the subject vehicles are equipped with a shift-by-wire system with a shifter control unit and parking pawl actuator motor. If a voltage fluctuation occurs when the vehicle is off and in Park, the signal from the SCU to the actuator may be affected. The problem could result in the temporary disengagement of the parking mechanism and a potential vehicle roll away.
Owners will be asked to return to the dealerships to have the Shifter Control Unit software updated. Drivers are recommended to use the Electronic Parking Brake (EPB) when parking their vehicles until the software update has been performed. Hyundai’s number for this recall is 228 and the NHTSA campaign number is 22V-324. Kia’s number for this recall is SC236 and the NHTSA campaign number is 22V-332.

Tesla will be contacting the owners of certain 2021-2022 Tesla model vehicles because of a problem that could cause the infotainment central processing unit (CPU) to malfunction.
The vehicles affected by this problem include:
|2022 Tesla Model 3
|2021-2022 Tesla Model S
|2021-2022 Tesla Model X
|2022 Tesla Model Y
In December 2021 during routine High Temperature Operation Endurance (HTOE) testing on the Model 3 and Model Y vehicle platform central processing unit (CPU), throttling was detected from thermal protections being engaged. An investigation into thermal management was initiated using vehicle alerts to follow the condition in the field. During this time, Tesla Engineering worked on a series of test experiments to identify the potential cause of the overheating condition. In April 2022, Tesla completed its investigation and confirmed the suspected root cause and affected vehicle population. The findings were reviewed and a recall was initiated.
According to the defect report, during fast-charging or preparation for fast-charging, the infotainment CPU may not cool sufficiently. Higher than expected temperatures could cause the CPU to slow processing or restart, and a lagging or blank center screen display. The problem could cause the rear-view camera display, windshield visibility control settings, drive modes (i.e., Drive, Neutral, or Reverse), and telltales to be unavailable.
On May 3, 2022, Tesla began deploying an OTA firmware update that will improve the management of the CPU temperature and associated communications with elevated temperature operation. This remedy will mitigate temperature elevations in the CPU when the vehicle is fast-charging or preparing to fast-charge, which will prevent slow processing or restart. Tesla’s number for this recall is SB-22-00-009 and the NHTSA campaign number is 22V-296.
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.
A small number of 2021-2022 Chevrolet Corvette owners will be contacted by the manufacturer regarding a problem affecting the rear half shaft assemblies in their vehicles. According to the defect report, Some Corvettes may have a rear half-shaft assembly that is missing one or more ball bearings. If any ball bearings are missing, the half-shaft will eventually fail, resulting in a loss of propulsion.
In September 2021, a General Motors (GM) engineer carried out a warranty inspection of a rear half shaft recovered from a 2021 Chevrolet Corvette. The half shaft fractured and caused the vehicle to lose propulsion. Upon further inspection, it was found that the half shaft was missing two of six ball bearings. Follow-up, discussions with the supplier identified a potential failure in the inspection process that led to the miss-build. In October, the GM engineer submitted a report to GM’s Speak Up For Safety (SUFS) program and the supplier identified 19 vehicle identification numbers (VINs) containing half-shafts that may have been improperly inspected.
GM is not aware of any injuries or crashes related to this condition. In February, GM’s Safety and Field Action Decision Authority decided to conduct a safety recall for any 2021-2022 Chevrolet Corvette that may have received suspect rear half shaft assemblies.
Those receiving notices will be asked to return to their GM dealers to have the left and/or right rear half-shaft assemblies inspected and replaced as necessary. Owner notification letters are expected to be mailed in April. GM’s number for this recall is N212351320 and the NHTSA campaign number is 22V-091.

In December 2020, Toyota began an investigation into certain 2021 Toyota C-HR crossover SUVs after receiving field reports from the Japanese market alleging that when using the Traffic Movement Notification feature (a Japanese market feature not available in the U.S.), the vehicle radar sensor did not detect a vehicle driving in front of it. An inoperative radar sensor also meant that other features, such as Pre-Collision System (PCS), Dynamic Radar Cruise Control (DRCC), and Lane Tracing Assist (LTA) could be affected. In these cases, dealer technicians observed that the beam axis for the radar sensor was out of specification and adjusted it during the inspection. After completing the adjustment and initializing the radar sensor, the vehicles were able to detect the preceding vehicle.
According to the defect report, certain 2021 Toyota C-HR vehicles are equipped with a millimeter-wave sensor (radar sensor) and a camera to detect objects in front of it. These sensors also support certain driver assistance features, including the Pre-Collision System (PCS).
Under certain circumstances, the initialization of the radar sensor may not have been completed correctly, resulting in the PCS not being able to detect an object in front of it. As a result, the vehicle will not provide warnings or braking assist, and would not display a message or indicator to the driver that PCS is not functional. An inoperative PCS, without a PCS malfunction indicator to the driver, may increase the risk of a crash in certain driving situations.
As of January 2022, Toyota has not received any U.S. field reports or warranty claims related to this condition. Based on their investigation results, however, Toyota decided to conduct a voluntary safety recall campaign. Owners of the subject vehicles will be asked to take their vehicles to their Toyota dealer to have the radar sensor inspected and properly initialize if necessary. Toyota’s number for this recall is 22TA02 and the NHTSA campaign number is 22V-107.
