Problems with 2014 Tesla Model S POWER TRAIN

On average, the 2014 Tesla Model S starts to “feel” problems with the POWER TRAIN and its various aspects after 52 797 miles.

Recently reported POWER TRAIN problems on 2014 Tesla Model S

Subframe broke after 80,000 miles or normal driving. no accidents or damage to car affecting this area. just driving on the highway and all of sudden started to hear a thumping sound when accelerating or decelerating or backing up.

Sudden loss of range with 2019.16.x software update. my vehicle was one of the many vehicles that was effected by software update by tesla. i have lost about 30 miles in range and the supercharging speed is significantly decreased compare to prior to the software update.

I have a p85d and since recent software updates my range has dropped significantly.. my supercharger sessions have also become extremely slow resulting in almost an an extra hour to charge the car compared to before updates. these updates seem to be a makeshift cover for defective batteries due to high fire and explosion risk, which have occurred on other tesla cars. so instead of fixing batteries tesla reduced their capabilities across the board.

On may 20th, 2019, the subject vehicle was updated with tesla's software updates and lost over 20 miles overnight. the vehicle has suffered from a throttling of performance, charging speeds, and a lowered maximum battery voltage capacity which has led to a significant decrease in the number of rated miles available. tesla has denied a battery warranty replacement by claiming that there is no defect. tesla claims that the updates were issued to improve battery longevity and health. however, they are doing so to avoid replacing these under warranty and/or compensating owners for the loss in range. this appears to be in response to the growing number of battery fires that have occurred with tesla vehicles that are parked and not in operation. tesla has failed to communicate anything with regards to the safety of the affected vehicles and has continued to make adjustments to the software without providing owners with any notice or information that their vehicle may be affected. the owner of this vehicle was denied a warranty replacement after having the claims arbitrated with national center for dispute settlement, where the arbitrator found that there was no manufacturing defect. the subject vehicle continues to suffer from a high rate of battery loss when the car is parked and not in operation. the car has not regained any mileage as a result of tesla's most recent updates that have attempted to remedy the situation. the subject vehicle suffers form reduced charging speeds and is not capable of reaching the same number of miles as it did before.

My li-ion battery has been degraded recently by an over-the-air software update. i believe that this update is related to the recent battery fires (4 in ladt 4 months, including one in san francisco). only a few (100 to a few thousand i believe) of the teslas have been affected as mine has been. i am now concerned about the safety of my vehicle. will my battery catch on fire in my garage? i would like nhtsa to review the changes made by tesla and approve that these changes will be effective for the safety of my battery. or, does this point to a defective battery and should be recalled for safety reasons?

The bearing in the drive shaft is damaged and constantly whines during acceleration. i brought the car to the dealer in chicago two months ago. they said the drive shaft had to be replaced. they ordered the drive shaft and said it would be delivered in 7 days. i have contacted them numerous times and get no response.

Rear subframe failed at 78k miles. tesla response was i did harsh acceleration and street potholes were the issues. i was driving 20 mph when i suddenly heard knocking noise. i came to complete stop. looked around and underneath my car for any foreign obstacles. everything was clear so i put my car in reverse. heard loud knocking sounds from rear left tire. took it to tesla service, where i was told that this is not drive unit( part that's under warranty, which is hold by the failed subframe and was replaced twice prior, but the subframe itself) and its a safety issue. speaking of safety issue i had to go to the nearest tesla service, when i occurred this issue and advisor told me, they don't have time to resolve my issue right now , so i had to drive it 30 miles away to a different one, where i was told that this is safety issue.

I was driving on the freeway going approximately 60mph when i suddenly lost control on a slight turn to transfer freeways. i swiped into the right freeway wall and spun out doing a complete 180 and ended up on the left freeway wall. i didn't understand how i lost control when i was not going that fast, and the turn was not at all abrupt nor severe in angle. the side airbags were deployed, and when i exited the vehicle, the rear right tire and axle was completely dislodged. i never seen anything like it, and i couldn't understand how that would happen.

Three times in two weeks, i have almost been hit as pedestrian by an ev. they make no noise at low speeds and you'd be surprised how much you rely on hearing in a parking lot for of other wise parked (and silent) cars to determine which cars to look out for.

p85d lost power on road, "pull over safely". with tesla's latest firmware updat e0.167 pushed otu untested to all p85d cars, the car loses all power suddenly when driving. it leaves the drivers stranded in the middle of roads dangerously. tesla is not issuing a recall, and is trying to suppress this and many many other quality and safety issues by limiting the information to its forums only, and sometimes removing those information to support its high quality image, and sustain its bubble stock valuation. more details here in this thread. hope they don't remove the entire thread. http://www.teslamotorsclub.com/showthread.php/43075-p85d-lost-power-on-road-pull-over-safely -- was heading down a 45 mph road at about 57. had the cruise set. no cars in front. was taking a very slight curve in the road and the cruise disengaged by itself. no errors or anything, just as if i had tapped the brake or something. hmm... so i resumed it and it went back to work. less than half a mile later i disengaged cruise to regen to a stop to make a left at a light. a couple of seconds into that and i got this dreaded message: "car needs service; pull over safely". *js

my 2 day old p85d suddenly died in the middle of an intersection: tesla built these p85d cars with faulty electrical contactors that it was secretly recalling through its forums. the faulty contactors caused some newly released p85d cars to lose all power within first 100 miles. tesla should issue a public recall to replace the faulty contactors. tesla shipped the p85d cars with old seats , even when it charged customers for next generation seats. tesla needs to improve its processes and make sure it releases cars only when safe for public roads. i shouldn't be paying over $100k to go through these pains and dangers. more here: http://www.teslamotorsclub.com/showthread.php/40527-my-2-day-old-p85d-suddenly-died-in-the-middle-of-an-intersection my 2 day old p85d suddenly died in the middle of an intersection:- well ... my short range brand new p85d with 191km (120mi) died suddenly in the middle of an intersection (completely stopped moving) on -12c weather. even the heater stopped working. my 10 year old son and i had to get out and push it to the side. called my ds who called roadside assistance who put him on hold for 30 minutes and then told me that it will be an hour before a tow truck arrives. my son and i were freezing with no heater so i made my 80 year old dad come and pick us up. needless to say ... i am not impressed. i knew i was buy bleeding edge but a complete breakdown 2 days and 140km after leaving the showroom? really?
