Differential Unit Problems in popular cars



Differential Unit problem is a common vehicle problem that happens to most car brands and models. The following is a sample list of Differential Unit problems reported in most popular vehicles.

car   Differential Unit problem of Chevrolet Tahoe

The car is a 2007 Chevrolet Tahoe. Front differential started making a very loud noise. It became even louder in 4-wheel drive. While in 4-wheel drive the vehicle didn't feel right. I brought to the dealer who stated water got into the differential, and it had to be rebuilt. This is the 3rd time I have had an issue with the front differential. All 3 times, including this one, was due to the failure of the pinion seal. The first repair on 11/06/09 was covered under gms manufacturers factory warranty. The next 2 repairs, including this one, cost me a total of $1,435. 49. I can only wonder how dangerous it was driving around in 4 wheel drive with a differential that was ready to catastrophically fail?. This problem occurred on Friday, November 6, 2009.

car   Differential Unit problem of Chevrolet Trailblazer

The car involved is a 2006 Chevrolet Trailblazer ext. The vehicle's vehicle identification number (VIN) was 1GNET16S56_. Upon turning the four-wheel drive engaged unknown to me at the time because the selector switch did not indicate this. The truck became difficult if not impossible to turn at low speeds as this vehicle does not have a limited slip differential in the four wheel drive mode. While turning the tires on the outside of the turn make a larger radius than do the inner tires. Without any slip the vehicle tries to maintain the same linear footage travel by each tire. This causes the tires to bind lock up and skid during turns. I have researched this problem on internet forums and it seems to be a quite common occurrence and could cause crashes while turning. I have contacted the manufacture and the response was for me to take it to a dealer and pay for them to look at it. I declined their suggestion and offered the compromise of taking it to an independent mechanic at my own cost,to which they declined. Please note I did not ask them to repair the vehicle at their cost but only wanted them to examine the vehicle for defective design/material. This issue happened on Wed., Apr. 30, 2014.

car   Differential Unit problem of Chrysler Pacifica

The vehicle is a 2004 Chrysler Pacifica. I took my care into the sear auto center in annapolis, MD for a tune up and also asked them to check for the knocking noise under my hood as is was affecting my steering and making the car hard to steer when going around curves. I was told that the front end suspension needed to be replaced badly as the parts were severely rusted. I was also told that I would have to leave the car at the facility overnight as they were having problems removing the old parts due to heavy corrosion on the old parts and it would take more time to get the parts off and replace then with new parts. In December of 2011, I purchsed new tires and was also told that I needed to purchse new wheels because the current wheels on the vehicle were starting to rust. In September, I had my brake pads replaced and was also told that I needed new rotors because those were also rusting. I do not live in a flood zone, nor have I ever had my car in a flood. I was made aware of a recall by Chrysler yesterday of its 2004-2005 Jeep brand due to corrosion and wanted to submit this as there may also me Chryslers such as mine that have had corrosion issues from normal usage. A few years ago, I also had to have the rear differential serviced due to a leak and this may have also been due to corrosion. It was Wednesday, Feb. 8, 2012 when this differential unit issue happened.

car   Differential Unit problem of Chrysler Town & Country

The car involved was a 2000 Chrysler town and country. The vehicle identification number (VIN) is 1C4GP44R0Y_. 2000 Chrysler town and country with 54,000 the differential pin went through the transmission case. Fortunately, I was only going 5 mph and only had another 50 feet to drive. I mainly drive highway with my toddler and I am fearful of what could have happened had we been on the highway during our normal commute. My husband was a mechanic for 19 plus years and was able to quickly determine the problem. It is my understanding from experienced mechanics and Chrysler certified mechanics that this is a common issue with the vehicle and it a defect in manufacturing the transmission. This is not normal wear and tear. I contacted Chrysler on July 9th, 2003 to report the problem and see if they would cover the cost of replacing the transmission. I spoke with eric who refused to provide me his last name nor would he transfer my call to anyone else. He said he is the final deicision maker and that his manager's role is to manage people and no deal with customers. He also told me if was my fault for buying a used vehicle. It is not my fault the transmission malfunctioned. He also told me that I could get it installed for free since my husband was a mechanic. Eric hung up on me because I was continuously asking to speak to a manager. I did not get any resolution or assistance from Chrysler. I am in need of my vehicle being replaced but most importantly, I am concerned about the safety of other drivers if their tranmission also malfunctions at high speeds on the highway. Any suggestions on how I can proceed with Chrysler to have the transmission replaced?. This differential unit problem happened on Jul. 5, 2003.

car   Differential Unit problem of GMC Sierra 1500

The vehicle is a 2011 GMC Sierra 1500. The vehicle identification number (VIN) of this GMC Sierra 1500 is 1GTN2VE02B_. There is play in the rear axles that emit a clunking noise when I am slowly backing over a grade with the steering wheels turned. I demonstrated play in the rear axles to the GMC factory rep and he said the axle play is within tolerances. My contention is that the noise is not normal and that the grooves in the differential end or the axles that accept the horseshoe shaped keeper clips are machined incorrectly and putting excessive stress on the clips. Eventually the clips will fail resulting in the wheel coming off. I further argue that if the axle play is indeed within tolerances then the tolerances are wrong. I tried to make the incorrect tolerance argument to the factory rep by making an analogy to the corvair and he missed my point. The rear suspension on the corvair was also within tolerances and many people died. This differential unit issue occurred Jun. 26, 2012.

car   Differential Unit problem of Honda CR-V

The car was a 2013 Honda Cr-v. VIN of the vehicle was 5J6RM4H59D_. I started to notice a croaking (sounds like a frog) noise coming from the rear of the vehicle when lightly accelerating from a stop in drive or reverse and right before I come to a complete stop. I have had this vehicle for a year, which I purchased new and this sound started after 11 months of ownership. I took my vehicle to the dealership where it was determined that the noise is coming from a noisy rear differential pump motor (part of the awd system) per a manufacturers tech line summary article. Per the dealership and manufacturer, the manufacturer is aware of this problem and is currently working on a fix, but does not have one to date. Manufacturer has instructed dealerships not to replace any rear differential pump motors at this time. This issue happened on Tuesday, March 4, 2014.

car   Differential Unit problem of Honda CR-V

The car is a 2014 Honda Cr-v. Vehicle identification number (VIN) of the vehicle is 2HKRM4H77E_. I bought at 2014 crv end of sept/oct of 2013. Upon the first snow fall I drove the vehicle and had immediate problems. The car was not getting any traction, it was sliding around going down hills and upon trying to drive up hills it would stop without even trying to go up. It would stop and wheels would spin, the rear end spun to the side and I could not get anywhere. The amber awd lights came on and flashed, combination of both scenarios. I finally got it into the dealership as the problem got worse. The rear differential has been deemed defective (overheating issue to point of almost glowing and fluid overheated). The other problem I have had is that if the car was put into 1st or 2nd gear to aid slowing down on a hill, even from a stopped position, it would not respond. The car sped up going down the hill in first gear to approximately 40mph even with the brake on, which would not engage and the anti-lock brakes were engaging and not even trying to stop the vehicle. The car behaved the same even if on flat ground that had even a dusting of snow or even a little gravel. The dealership gave me a courtesy 2014 same year as mine, it drove much better and much safer than mine performed after the first 2 days. I feel the car has more issues than just the differential and is a major safety hazard as the last 1-2 weeks the car has had no control in anything other than dry roads. It has almost wrecked more than once due to these issues. This vehicle is 3. 5 months old and had under 10,000 miles on it and all of this has gone wrong since the beginning. This issue happened on Tuesday, Dec. 24, 2013.

car   Differential Unit problem of Infiniti QX56

The car involved was a 2008 Infiniti Qx56. My question is somewhat irrelevant now, seeing that the damage to my vehicles is already done. I have owned two vehicles made by Nissan, a 2004 armada le and now a 2008 Infiniti Qx56. On both of these units the front differential pinion seal leaked causing damage to the front differential bearings. I have heard of many others experiencing this same problem. Q. Can you please tell me why this issue has not been recalled by Nissan? it's obvious this is a major problem (among many others with this vehicle) that Nissan chooses to ignore. The failure date was 03/07/2014.

car   Differential Unit problem of Infiniti G37

2009 Infiniti G37x coupe is experiencing dangerous surges in acceleration upon braking, the transmission is jerking and going into "fail safe mode" (meaning suddenly the car is stuck in the highest gear), the rear differential is clunking and jerking as if the car is going into awd mode at times it should not be, and quite frankly I am now becoming scared of the car. It has 3800 miles on it. I took it into the dealership on Friday and was told there are a couple of known issues with the transmission but no fix. They also are calling hq on Monday to talk about it. I do not want to leave my car to be driven around erratically as they try to "break" it as that will cause further damage to the transmission and engine as well as put more miles on the car. Infiniti service agreed that remapping the computer would most likely take away the specifications of the car which are what they market and I bought the car for (horsepower, acceleration, "same as a BMW". If they have to gut the power of the car to fix the problem, I feel this is false advertising and the car is not what I contracted to purchase. I am on the verge of watching my resale plunge before the car is even six months old and believe Infiniti should have to replace the vehicle. This problem is happening repeatedly everytime I drive the car. See notes below: 1. Central computer clearly failing - had to be restored yesterday. 2. Reaf diff clunking in and out of awd loudly and with a jerk and at unexpected times 3. Surging rpms as much as 5000 upon driving 4. Surging rpms and acceleration upon braking (3000 rpm) 5. Hanging instead of downshifting 6. Very jerky downshifts 7. Tranny went into failsafe at least 3 times now (meaning no gear below 5th is available at any time). It was Mar. 10, 2010 when this differential unit issue occurred.

car   Differential Unit problem of Jeep Grand Cherokee

The vehicle was a 2008 Jeep Grand Cherokee 4x4. The vehicle's vehicle identification number (VIN) is 1J8HR58N58_. While off road very far into the desert of arizona I was traveling with my permanently disabled wife. We were on desert trails and the trail lead into a soft silt type dry wash. When I tried to put this Jeep into 4x4 low range a message popped up in the interment cluster that said "service 4 wheel drive". The Jeep would not shift to 4x4 low range and lock the differential and drive through the dry wash to safety. This problem is directly related to the "safety recall n23 / NHTSA 13v-175 reprogram final drive controller module" that a jep sevice center had preformed. The final drive controller module (fdcm) (n23 / NHTSA 13v-175) re-programming that I had performed at a Jeep service center caused this potentially fatal problem that could have left my wife dead. If we hadn't had water to drink or if it would have started to rain we(she) could have drowned in the wash while being trapped in the Jeep, because I could not place the Jeep in 4x4 low range and lock the differential to drive the Jeep out of a potentially fatal situation. The failure date was 02/15/2014.

car   Differential Unit problem of Lexus RX330

The vehicle involved is a 2005 Lexus Rx330. I am having serious quality problems with my 2005 Rx330. The vehicle is kept in the garage and being taken care of like a family member. I took the SUV to a Lexus dealer for routine maintenance and was told that the stearing column was leaking and need to be replaced - approximate cost $1800. I was also told the front differential was leaking and need to be replaced - cost another $1000. This is not the end! approximately six months ago my water pump failed at the middle of a busy intersection, and I had to replace my water pump, timing belt, drive belts, etc only at 65k miles - cost $1200. Why every major key components are failing so early? I drove a car made by a competitor upto 110k miles without any of these issues. Lexus/Toyota is using defective/cheap parts at the expense and safety of consumers. I would recommend starting an investigation against Lexus/Toyota for faulty steering and power train components in RX, and based on the investigation, start a recall if needed. I reached out to Lexus in the past, but they don't acknowledge any quality problems with Rx330; however, when I searched the internet, I see hundreds of owners have the same issues and they are helpless. Lexus will not do anything, and therefore, we need NHTSA's help to push Lexus to recall Rx330 steering and power train components. It was October 13, 2012 when this differential unit issue occurred.

car   Differential Unit problem of Lincoln Aviator

The VIN of the problem Aviator is 5LMEU78H03_. The shifter knob on my 2003 Lincoln Aviator broke off. The shifter was locked in place in drive and you are unable to shift into any other gear except the gear you're in. It seems that a very cheap plastic piece broke under the shifter knob and the dealer quoted me $1200 dollars to replace the entire shifter assembly. I have checked online and seen that this is a very-very common problem among owners. There is no recall for this issue, but this is surely a severe safety issue. I am not sure how many complaints it takes but this is a horrible safety issue. Also, this vehicle has a whole array of front and rear differential issues along with a severe clunking noise when the vehicle is 1st put into reverse, drive or downshifts after acceleration. This differential unit problem happened on 09/24/12.

car   Differential Unit problem of Mitsubishi Lancer

The car is a 2010 Mitsubishi Lancer evolution. While driving the vehicle in warmer weather, a warning (4wd system service required) is displayed on the dash and the s-awc awd system is disabled. The active center differential and torque biasing rear differential are disabled, which greatly reduces handling and causes the vehicle to react differently than normal in emergency situations. This is the result of a failing acd/ayc hydraulic pump. Mitsubishi will not cover these pumps under the power train warranty, even though it is a very common problem. The pumps corrode internally and are unable to build and maintain pressure. It was May. 7, 2014 when this differential unit issue happened.

car   Differential Unit problem of Mitsubishi Lancer

The vehicle involved was a 2008 Mitsubishi Lancer evolution. This is report of a known failure by Mitsubishi motor corp. At 50,800 miles on 12/17/2013 my cars super-active center differential (s-acd) started blinking at me. It would not allow changing of the settings anymore for tarmac/gravel/snow. Immediately there after, the driver information panel popped up with a yellow "awd service required" indicator. I brought my car to nashua, nh Mitsubishi/Hyundai for diagnosis on 12/19/2013. There they applied TSB-sc11-002. This unfortunately did not resolve the issue. I was then informed that the car required a replacement acd pump and was quoted $1,995 for the repair, which confused me due to the fact that my car was still under manufacturers power train warranty, and a pump, that controls the awd system of a car, seems to be power train related, at least in my eyes. The north east regional representative was contacted on my behalf by the dealership to request coverage of this item, which was ultimately denied. This is a severe safety issue, as the car no long handles properly in conditions it was designed for. I am no longer able to select the car for snow, living in the north east, driving a car marketed in the north east, this is a huge problem. To further the issue, this problem is well known by Mitsubishi, it has been documented well, tracing all the way back to cars manufactured in 2006. 90% of all pump failures could be completely eliminated by adding a seal to stop corrosion inside the pump which leads to the untimely failures. If no recall is issued for this failure, at the very least, Mitsubishi motors should be forced to cover this under power train warranty for 5yrs/60k miles. Instead of limiting it to 3yrs/36k bumper to bumper. This problem occurred on Dec. 17, 2013.. Read more...

car   Differential Unit problem of Nissan Frontier

The car was a 2008 Nissan Frontier. The vehicle identification number (VIN) of the car was 1N6AD07W08_. Noticed oil / grease on rear tires sidewall. Taken to Nissan dealer for inspection. Mechanic found a failure of both rear axle seals causing fluid to cover rear axle, differential, rear brakes, and tires. I was advised to not drive the truck due to possible axle and wheel separation from the rear end. If I had not found this I could easily be dead due to wheel axle separation from the vehicle in motion. This is a major safety issue and the vehicle recalled for this problem. After repair was performed the mechanic told me the rear axle housing vent tube clogged causing pressure to build up blowing out the rear seals. Nissan corp. Usa was notified but declined to assist customer with extensive repairs stating that although being under the 60,000 mile power train limit the vehicle was 5 months over the 5 year age limit. Nissan corp. Usa did not view this as a safety issue. This issue happened on 03/27/14.

car   Differential Unit problem of SAAB 9-2x

The vehicle having this issue was a 2005 SAAB 9-2x. Purchased car approx 2 months ago. Odometer read 24,200 miles. Within two months, and 2,000 miles, the car has been in for a whining noise, alarm, power steering, and an air compressor. After 3 weeks back and forth, I am now on my third differential, second air compressor, second power steering pump, and second alarm speaker. Tomorrow I go back to the shop for the same whining noise, the alarm speaker (out again), the air compressor (extremely noisy), and fuel economy only reaching 12 to 13 mpg(rated 19 to 26). The dealerships "tech center" said that the noises were inherent, but if so, why would they replace the differential twice, and why would it get progressively louder in a weeks time. I loved the car when I bought it, but now it feels as if I bought a lemon. I have been driving loan cars longer than my own. This differential unit problem happened on Monday, Aug. 13, 2007.

car   Differential Unit problem of Subaru Impreza Sti

The vehicle was a 2008 Subaru Impreza Sti. Check engine light went off, flashing cruise control, and flashing differential selection [s] code. Brought the car to the shop and had it checked out. The error code is p1410 which translates to something wrong with the secondary air injection system. Most likely one of the valves (or both) that operate with this system is rusted stuck the open or closed position (worse if its stuck open). Checking multiple forums this is happening regularly and Subaru is choosing not to cover it under warranty and/or recall. The part was poorly designed and is subject to rust/failure in humid, rainy, or snowy environments. This can be dangerous when driving as it puts your car in a limp mode turning off the cruise control unexpectedly and possibly forcing your car out of its multiple driving modes (via selector in the center console near the armrest below the shifter). I am not sure how damaging that could be to hard switch the mode while running at high speeds but there is the potential. With the amount of people complaining about this known problem with the Subaru wrx sti (which is their top dog sports car) there is no reason for there not to be some kind of resolution/recall for this faulty part/design. To top it off, the repair costs for this is astronomical in the $1000+ range from the estimates I am getting. It was April 23, 2013 when this differential unit issue occurred.

My local garage repaired my car, I received 4 new spark plugs, and an air filter. 9 days later the check engine light came on, as well as the cruise control light, and the vehicle dynamics warning light, again it was repaired, this had to do with the catalytic converter message, but all my local garage could find was a small leak near the manifold that they repaired. 2 days later the check engine light went on again, I now called my Subaru dealership, they replaced a faulty catalyst converter, and af sensor, the also changed my oil, as it was due, and suggested I have a transmission fluid flush and refill, and that my rear and front differentials, needed a drain and refill. 5 days passed another check engine light, this time it was flashing, I had to have my car towed, the Subaru dealership discovered the wrong spark plugs were put in initially, and replaced them with platinum tip spark plugs that my model takes. 4 days passed another check engine light, with being unable to accelerate, I was going up hill, so I continued on, to reach a parking lot, I could stop in but suddenly, it felt like something unblocked, this made the check engine light go away, until 2 days later, another check engine light, I once again brought my car back to the dealership, the mentioned something about the catalyst converter, but said it was 'too soon" so they left the work order open , in case it occurred again,and gave me this lecture about the grade of gas I am buying. 4 days later the check engine light returned, this time Subaru discovered the my other O2 sensor was faulty, and they would replace it, when the part comes in. This issue happened on Oct. 3, 2012.

car   Differential Unit problem of Volkswagen R32

The vehicle identification number (VIN) of the car was WVWKG61J74_. Car: 2004 Volkswagen golf R32 whinning noise coming from the rear differential. Alot of Volkswagen R32 owners are starting to hear a whine from the rear differential, usually on deceleration or lifting off of the gas pedal. We communicate with each other through a vw enthusiast forum. The majority of us who encounter this noise have checked and changed our rear differential fluids and have found that our fluid is low from the factory!! the capacity of our rear differentials is 1 liter, per specifications. Most of us have found when draining the differential, that only 1 cup drains out, some even have found that the differential is not filled at all!! after filling with new and proper fluid the whine still is heard. Please send something out! I would hate to see some one get injured due to a failed rear differential on the vehicle. Possible lock up due to heating and welding of the gears can happen due to lack of fluid!. This differential unit problem happened on Mar. 5, 2007.

We own a 2005 Volvo Xc90 and it has 54k miles on it. We heard a whining sound from the rear and took it to the dealer and they said the rear hub bearings need to be changed. We were not convinced and took it to our auto mechanic who works on our avalon, he looked at it and after spending 5hrs on it came to the conclusion that it was the rear differential. We went back to the Volvo dealer and asked him to check again and said it may be the transmission. They came back and said yes it is the rear differential and it needs to be replaced. The price tag was for $5200. This seems to be the problem with all the Xc90's. We are afraid to drive this car on the highway never knowing when our transmission will give way.

car   Differential Unit problem of BMW Z3

The vehicle involved is a 2000 BMW Z3. VIN of the vehicle was 4USCH9349Y_. On 24jun2011, I swerved from a parallel lane to avoid being sideswiped. No contact was made between vehicles. However, I noticed a noise coming from the rear of the vehicle. The vehile has a manual transmission. I took the vehicle to an auto body repair shop. After examining the vehicle they told me that: the flange/bracket that held the differential in place had a complete hair-line fracture; and, that a substantial number of spot welds holding the body on to the frame had failed. I made contact with the local BMW dealership mcgrath BMW, ocated in westmont, IL and told them of the incident. They stated that they did not undertake body repairs and directed me to a firm which did all types of body and structural repairs and was accredited by BMW. I was given an estimate for the repair of between $5,000-$6,000, and was told that there was no program offered by BMW to share in the cost of the flange/bracket and body repair. I went back to my local body shop and told them to estimate the cost and I also reported the problem to my auto insurance (state farm). An adjuster from state farm reviewed the failures and stated that the condition was one of a problem in manufacture and not covered by my auto insurance. My body shop then gave me an estimate of a not to exceed figure of approximately $2,500. I told them to undertake the repair. The flange/bracket has been replaced and reinforced and the body and frame have since been rewelded at a total cost to me of $1600. Additionally, I spent an additional $100 for a alignment (firestone of countryside, IL) the local body shop is douglas auto body, 4015 eberly avenue, brookfield, IL (708) 485-7774 - they are a body and structural repair shop approved by state farm insurance. This vehicle has been used by me as a street vehicle and not for racing or track use of any kind. The failures seem to be a mfg. Design flaw. It was Friday, June 24, 2011 when this differential unit issue occurred.

car   Differential Unit problem of Buick Rendezvous

2003 Buick Rendezvous. . . Making humming noise when turning wheel. Very bad. I took it to a garage and they tell me it is the differential, that it will take 9 pints of fluid to flush it out at 29 dollars a pint! if I don't get this done, it will freeze up and will not move. I came home and looked it up on the internet and cannot believe what I am reading. Every person that has had a Buick Rendezvous , this has happened to. I am not talking a few, there was about 300 of them , just posted on the internet. Why would there not be a recall on this? I would really consider that all of them doing this is definitely a defect somewhere. One woman even stated that she had to do this every year that she had it!!! these are not cheap cars to own. I have only had mine 1 year and have put 2000 miles on it. It now only has 55, 000 miles on it. I would like to know what qualifies a recall? I am sure I will be letting it sit while I am still making another 4 years payments on it. No way can anyone afford to keep fixing the same thing every year. It is going to cost between 450 and 625 to fix it. . . The mechanic told me and then couldn't promise that it would stay fixed. I think something should really be investigated on this one. I hope you check out the complaints online concerning this. . . . Thank you!. This differential unit problem happened on Thursday, Aug. 27, 2009.

car   Differential Unit problem of Cadillac CTS

I am concerned about a know differential issue with the Cadillac Cts. In forums every where I am reading that the differential first leaks and then grenades. I know you are only requesting information when it grenades, but I think issues should be stated immediately! I don't want to be driving down the road with children in the car and have problems then. I contacted Cadillac first and received the heisman stiff arm. I think this is a significant flaw in the Cts dating back to 2004 and should have a recall!.

car   Differential Unit problem of Cadillac SRX

The vehicle having this issue was a 2008 Cadillac Srx. Differential leak. This is a recurring problem. Oil leaks from the vent. It was repaired under warranty once and it has to be repaired again. The vent is a defective design and we now have not only our vehicle but many vehicles spewing differential oil all over. Gm could easily provide a better design vent but unless the NHTSA makes them nothing will happen. The TSB for this item obviously does not work as many owners are having this problem over and over again. Recall these vehicles so we stop leaking oil into the environment and possible cause expensive damage to our vehicles. It was Mon., Jan. 20, 2014 when this differential unit issue happened.

car   Differential Unit problem of Jaguar X-type

The vehicle involved is a 2007 Jaguar X-type. The vehicle identification number (VIN) of this Jaguar X-type is SAJWA51A87_. The engine stalled out when we were traveling in the passing lane at speed on an interstate highway. We had to move to the right side shoulder of the highway in front of another vehicle we had just passed and other traffic coming close behind. Definitely a scary situation for us and the other drivers. We were towed to the nearest jag dealer. The dealer had our car for two weeks. They replaced the fuel pump. The service tech's told us that they had never heard of a fuel pump going bad in an X-type. When I questioned the cost of the job, about $1450, I was told that the fuel tank had to be removed to replace the fuel pump. Since that time, we have had a battery replaced, the second for this car since we have owned it, and had to have brake pads replaced, at which time, we were told that the rear brakes had a problem in the calipers that caused the pads to sit further from the discs than they should. This brake problem causes us to use extra pedal travel when braking the car. Then, on Dec 9, 2013, the rear differential fell out of the bottom of our car. We were only doing about 20 mph so there was no accident, but we had to be towed to a jag dealer about 30 miles away. My research found that when the fuel tank is removed, the differential would also be removed. This was confirmed by the service writer where my jag was towed. One of the differentials bolts broke where it appeared to have been cracked, as if it had been over torqued when installed! the service writer asked to see the work order for the fuel pump work, so I asked him to look it up. He was not able to find the info, because the work was done out of warranty and the jag system does not record out of warranty work! that is probably why the techs never heard of a fuel pump going bad or a differential falling out of a jag car, even though there have been examples of both reported here!. This differential unit issue occurred Friday, December 21, 2012.
