Lexus RX350 jerking problems

Filed May 3, 2021 · Transmission · 12,500 miles · FL

We took the car in because when the car is cold it does not shift properly. This problem has been happening and getting worse since it was there for a recall on the transmission software. Dealer refuses to acknowledge that there is a problem stating the diagnostic computer shows no error codes, while ignoring the fact when you shift from park to reverse or drive the vehicle jerks and the gear lever requires a lot of force to move into desired gear. Dealer refuses to repair the car or acknowledge the problem, instead they tried to sell me a $875 oil change. Dealer is also refusing to send me any paperwork that my car was there even after calling many times to request it, they promise to send it that day and never send it because "they are busy". Service advisor david ( taou) was very arrogant, condescending and dishonest.

The car abruptly jerks forwards or slows down when switching gears. There is a knocking sound when you accelerate. The RPM increase to 6k-7k before the next gear is engaged and then car abruptly thrusts forward. The car accelerates and decelerates randomly. This car cannot be driven safely in this condition. The car only have 1116 miles and is a 2019 model.

1.constant jerking sensation occurs before vehicle shifts into lower gears while at relatively low speeds and throttle settings (25-45 MPH, stop and go city driving, maintaining speed). 2.when minimal increase in power is needed or a mild grade is encountered, additional throttle pressure seems only to result in loss of power until the transmissions shifts into some lower gear. The vehicle then accelerates too rapidly, followed by the need to reduce throttle pressure ' or apply brakes - which in turn causes the transmission to shift back to a higher gear. The sequence then repeats itself. 3.note: poor drivability issues are reduced when the engine is cold. Also keeping RPM above 2000 helps. 4.depending on driving conditions, the vehicle will accelerate well while shifting up through the gears but seems to loose power as RPM drops, forcing a downshift or increased throttle position. 5.when under slight engine load, the suspension seems to amplify road bumps, to the extent of finding bumps where there are none. This condition is reduced while at idle throttle settings and coasting. 6.a recent drive through the mountains prompted me to resort to manually shifting the transmission to improve drivability because of hills and curves. 7.I frequently resort to driving in s4 except for interstate driving so as to keep RPM above 2000 to improve drivability. 8.frequently the engine feels to be missing, resulting in vibration through steering wheel and accelerator pedal. 9.on four occasions since ownership the rx has suddenly and expectantly accelerated for unknown reasons, forcing emergency breaking. This is an extreme safety issue. 10.when using cruise control (~65 MPH) and if the set speed is reduced a couple of MPH, the RPM jumps to 6,000. 11.transmission slow to choose a gear when accelerating into traffic.

The transmission on this vehicle is bad! The dealer keeps saying it's normal in the learning phase, but there is no way all of this sputtering and hesitation is normal for any vehicle, let alone a luxury one. The tachometer jumps, jerks and sputters as well if you watch it. The pre-collision break system is also severely flawed. It has braked so hard that it screetched and no one was even around me!!!!! This clearly almost gave me a heart attack three times now. It has happened twice when slowly backing out of a parking spot, and one time while driving down the street at a normal rate of speed and no one was around me at all.

There is a huge delay in acceleration. Sometimes, when merging or passing, there is a very noticeable dead spot where the vehicle will not respond when you need it to. Throttle response also is often very jerky and difficult to drive. This has been a problem since I bought it. Lexus says this is normal and offers no solutions. Many people seem to be having problems with this vehicle, please make lexus issue a recall.this car was very expensive.

Tl* the contact owns a 2016 lexus rx350. While driving various speeds, the vehicle jerked without warning. The vehicle was taken to lexus of las vegas (6600 w. Sahara ave, las vegas, nv, 702‑942‑6600), but the technician was unable to duplicate the failure. The failure recurred and the vehicle was taken back to the same dealer. The manufacturer was made aware of the failures and referenced tsb number: l-sb-0109-17 to the dealer. The technician resettled the transmission according to the tsb instructions. The vehicle was repaired. The failure mileage was approximately 500.

The transmission has three settings. In any of them, start up often results in erratic shifting, rough acceleration and sometimes abrupt lurching forward. This has resulted in alarming shifting and acceleration. The shifting from one gear to the nexr is not smooth nor contributes to safe start-up in my opinion - and I am over 80 and have driven many cars and trucks - worst shifting in my experience and is dangerous. Dealer says is normal.

Intermittent hesitation of the transmission. Put in gear (forward or reverse) and vehicle won't move. Rev up engine and it surges-jerks forward or reverse.

I had braked to a stop on a city street in bumper-to-bumper traffic that was stopped for a red light. Suddenly and unexpectedly, my car accelerated forward though my foot was still on the brake. It made a noise like the engine was accelerating. My car lurched forward and struck the car in front. As he moved forward, my car again struck it. I had to put my car in parking gear to get it to stop moving. I had my car towed to the lexus dealer. They checked and said they could find nothing wrong and they couldn't replicate the problem. I asked them to check the event data recorder that I had read about online. They said the car had no such thing. Nobody should drive this car - somebody could get hurt badly if that unintended acceleration happens again. I lease this car and will terminate the lease. I hope whoever thinks of buying this car will see this report and stay away from it. It is unsafe.

Initially felt the vehicle suddenly lurch foward on several occasions after backing out of parking space at work and shifting into drive. Had to hit brakes, bring the vehicle to a complete stop, and then slowly start forward again. Accident occurred in the driveway of a private residence. The vehicle was placed in park and fully stopped.. Driver was about to turn off engine and, with passenger, exit the vehicle when it suddenly accelerated for no reason, plowing straight into the garage door of residence. Garage door was completely torn off and the vehicle came to a stop after smashing an interior wall and doorframe. Thankfully, no injuries but could have been worse if the windshield had broke. The vehicle was damaged on 3 sides and the property sustained damage to the garage door, interior drywall, door and doorframe. Again, the vehicle was completely stopped and in park when it suddenly accelerated.
