I am reporting a serious vehicle safety issue caused by negligent service performed by Tony T’s Chrysler Dodge Jeep Ram, located at 7250 Gulf Freeway, Houston, TX 77017. The dealership performed a borescope inspection of the rear differential on my 2016 Dodge Challenger SRT Hellcat, as documented on my invoice. After this service, it was discovered that critical differential plugs were removed and not reinstalled, multiple fasteners were missing, and the differential assembly was left loose to the point it could be physically moved by hand. This condition created a significant safety hazard, including risk of fluid loss, overheating, drivetrain failure, and potential loss of vehicle control while driving. The issue was confirmed by another repair facility. I have photo and video evidence, as well as the service invoice. The vehicle was unsafe to operate and out of service for an extended period, resulting in financial loss and safety risk. I request that the National Highway Traffic Safety Administration investigate this incident as a potential safety issue related to improper service practices.

Center bond of crankshaft Damper falling-off front of engines on the highway due to defective bonding material in manufacturing causing failure in rubber bonding. At highways speeds, a 10lb chunk of metal will fall-off HEMI engines & create a flying projectile at other motorists on the road causing damage or death to other vehicles/drivers and/or pedestrians. Owners who are unaware of this safety-issue will be unaware that their crankshaft-damper has fallen off due to not realizing a piece of the engine is now missing, thus creating possibility of engine failure due to No Vibration Dampening any longer attached to the crankshaft pulley.

Was taking off from a red light, got to about 15 MPH and there was a loud bang and I felt it from under the car. It then felt like I was dragging something under the car, but that couldn't be as I was behind another car and if there were something in the road, they would have hit it. I managed to pull over to the side of the road. I put it in park and tried to turn it off. It wouldn't turn off and the "P" on the shifter was blinking and so was the "Run" light. It was at that point smoke started coming from under the hood. I grabbed my belongings from the passenger compartment, but couldn't open the trunk. It was then that flames started showing. I got away from it and started calling 911. Just then a police car arrived and they radioed for fire. It was afterwards I noticed that from the place it happened, to the spot I was able to stop, there was a long line of transmission fluid and when they towed the burned car, there was lots of transmission fluid. The car had low mileage and maintained as required. It was still under extended warranty. I contacted Chrysler customer care and they had the car "inspected" but found nothing to have gone wrong and that fires happen. This is wrong and unfair as there was a major mechanical issue that resulted in a fire and the loss of my vehicle. If this had happen a couple minutes earlier, I would have been on the freeway and certainly would have crashed and possibly died.

The drive shaft carrier bearing has disintegrated causing the drive shaft to bounce all around unsupported in the drive shaft tunnel. The carrier bearing is located in the middle of the two piece drive shaft. This could cause the drive shaft to break and fly out from under the rear of the car and smashing into the car behind and causing a serious or possible fatal accident, or if the drive shaft drops down towards the front of the car this could this could dig into the road causing the rear of the car to flip up causing a serious or fatal accident. There are no warning lites or indicator. This is happening in many 2016 Dodge Challengers. You can find this out throughout searching in any dodge websites.

18V332000 · Electrical System:software; Electrical System:wiring; Vehicle Speed Control:cruise Control

May 17, 2018

Chrysler (FCA US LLC) is recalling certain 2014-2018 Dodge Journey, Charger and Durango, RAM 2500, 3500, 3500 Cab Chassis (more than 10,000lb), 4500 Cab Chassis and 5500 Cab Chassis, Jeep Cherokee and Grand Cherokee and Chrysler 300, 2014-2019 RAM 1500, 2015-2018 Dodge Challenger, 2015-2017 Chrysler 200, 2016-2018 RAM 3500 Cab Chassis (less than 10,000 lb), 2017-2018 Chrysler Pacifica and 2018 Jeep Wrangler vehicles. These vehicles are being recalled to address a defect that could prevent the cruise control system from disengaging. If, when using cruise control, there is a short circuit within the vehicle's wiring, the driver may not be able to shut off the cruise control either by depressing the brake pedal or manually turning the system off once it has been engaged, resulting in either the vehicle maintaining its current speed or possibly accelerating.

Consequence & remedy

Consequence: If the vehicle maintains its speed or accelerates despite attempts to deactivate the cruise control, there would be an increased risk of a crash.

Remedy: Chrysler will notify owners, and dealers will inspect the software, and perform a software flash on the engine or powertrain control module, free of charge. The recall began June 4, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Note: Owners are advised to stop using cruise control until the software update has been performed. In the event that cruise control cannot be disengaged while driving, owners should firmly and steadily apply the brakes and shift the transmission to neutral, placing the vehicle in park once it has stopped.

EA21002 · Desiccated Air Bag Inflator Rupture

Opened Sep 17, 2021 · No close date supplied

Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.
