Acceleration hesitancy

[deewan]

Who launches a new car line and has zero parts available for it??

There are a LOT of companies with vehicles that are having part supply chain issues, not just car companies. Anthem Audio/Video had to delay the release of a their flagship processor one year because of lack of parts. Due to complaints, Anthem released their second to the top level processor and a few people who had issues had a parts supply problem.

It's not uncommon for manufactures to keep people employed and have them build what they can as they wait on part shortages. I'm currently located in Kansas City, MO. There are three HUGE parking lots that I know about (found a new one last night while driving home from the vet) of F-150 tucks, many of them being the Lighting (electric) version. All these trucks are sitting in parking lots around the city because of lack of parts.

Ford needs to install seat belts, ECU and conduct software checks on production F-150 pickups parked in lots around the Kansas City Assembly Plant, Parking lots around Kansas City, as well as thousands in lots around metro Detroit, while some dealers await deliveries of America’s bestselling truck, Ford confirmed to the Free Press.

Normally the parking lot at Worlds of Fun is empty this time of year. But when you drive by on I-435, you'd think it's the middle of summer because of the vehicles parked there. While it sucks to be without a vehicle you purchased and enjoy driving, these things happen. The other option is to not buy a new vehicle during this time or manufacturers to not offer them for sale.

I have read in this forum a couple of times where people are complaining about lag and hesitancy when accelerating and I think most of us have chalked it up to turbo lag and how people are driving.

However, I had this happen this morning for the first time and it is a real "thing"! It isn't turbo lag - I've been driving this vehicle since September and it has never done this before.

If I'm stopped and floor it, there is a 1-2 second delay before there is a response - I always thought this was exaggerated, but it isn't!

When I'm driving about 40 KMH in the city - in ECO, Comfort or Sport mode - I can press halfway down on the accelerator - and nothing happens! If I floor it, there is a delay and then a response, but I was very concerned that NOTHING happens even pressing the accelerator halfway down. Interestingly, the fuel consumption gauge jumps up as soon as I press the throttle...but the RPM doesn't change! It seems like the transmission needs to shift down to respond and it doesn't do its job.

I mentioned this to my service manager - and I have an appointment to do some other work on Thursday anyway, so they are going to look at this. They believe that this is a tranmission issue. They are going to reset the electronics on the transmission and they say it takes a couple of weeks to relearn my driving habits and are hoping this will resolve the problem. I'm hoping it's that simple, but I wanted to post this since this is an actual issue!

I have had similar issues. It started occurring when I went around a corner. My GV70 felt like it was going to stall. This happened several times including one time when the car lurged forward. It then happened on a strait away when I couldn’t accelerate over 30mph. I took it to the dealer and they drove the car and noticed the problem. . It has been at the dealer for one week and I have heard nothing.

Yeah, but those are waiting for a few key parts and that we are coming into a chip glut which should clear out a lot of these vehicles. In this case, we are talking about parts that should not be constrained. My concern is that Genesis is not taking the new entry luxury car disturber role properly. They need to be like Lexus when they entered the market. Genesis has the right product, and I can forgive them about the inherited dealer network problem somewhat, but there are too many consistently failing parts (quality control?), and waiting weeks for replacement parts is just not acceptable. Customer experience is not good (although to be fair, some dealers are trying hard). Genesis, you only get one chance to make a first impression.

Now with a car accident on the CarFax, I would lose a lot of money in trading it and I probably have more than the average amount of mileage on it, so that's not a great option either. A buy back would be a much better option but it looks very rare in Canada.

That sucks, I had no idea Canada didn’t have lemon law. What do you have there, it would suck to have a lemon car and you’re just stuck with it.

There is an arbitration process we can go through but there are only a tiny percentage of people who get what they want that way.

On the plus side, I got my car back yesterday with a new throttle body and the problem has gone away! This was definitely the fix!

 

[resdoggie]

I've only had to use the arbitration process once for a Ford vehicle. Once I made the dealer aware that I had filed a claim, within a few days I got a call from the dealer saying they would replace the faulty part. I guess just by filing a claim in my instance prompted Ford and the dealer to do the repair at no charge. The part was a catalytic converter which was under the emissions warranty at 94 months - 2 months before expiring at 96 months.

Update...getting worse now.

If I'm on the highway, driving 100 KMH and I floor it, it shifts down and the RPM sticks at 5,000 RPM. It will not increase speed or shift up...just stays static at 5000 RPM until I let off the gas, then I can speed up slowly if I don't press too hard on the accelerator.

Something is very seriously wrong!

I have this same issue on my 2.5t GV80. Thanks for let us know the throttle body fix worked as I'll suggest it to my dealer!

My car is doing the same thing- the hesitating, stuttering, stalling thing except it turn itself off and all the dash lights light up. Had to wait 30 seconds in the middle of traffic to restart the car. Service appt scheduled for June 30th. Gonna drive around my neighborhood tomorrow and see hiw to duplicate this prior to my appt. The only thing I did before it happened was put my car in custom mode to test it before driving off.

If it actually stalls, that could be the fuel injector issue quite a few people have had. Hard to get replacement parts too by the sounds of it...

I have a 2021 GV80 with 40,000 Km on the odometer and had the same issues regarding low end acceleration and top end acceleration while travelling at 100 kmh: when pedal is pushed down, transmission shifts to 3rd and then it revs with no acceleration. Definitely not safe to drive on the highway. The dealer called and said the water pump needs replacing and the part is on back order. Luckily they’ve provided with a replacement car in the meantime.

Yup, that's the problem I had with the throttle body. Unrelated to the water pump...

Greetings from Australia.

I’m having something similar but not necessarily the stalling part. Surprisingly it actually went away for while after leaving the car sitting for 2 weeks while overseas. Symptoms has come back since and it’s due for service in a week.

How did they actually diagnose the throttle body problem/failure on your car? The last time they towed mine in, they couldn’t find anything.

 

[dhuhtala]

They had to take a portable code scanner on a test drive with them and capture the issue while it was happening. It won't come up when it's sitting in their shop...

Glad I found this because I had a scary situation last week. Turning right onto another street using a short curved merge lane. I was almost coming to a stop, braking, looked left and traffic just got the green light so though I had plenty of time to merge in front. So, released brake, hit the gas, and.....nothing....just lagged...badly, but was still moving forward so front end was now half into the lane with vehicles heading my way coming through the intersection, and it would not go. Happened so fast but I think I released then repressed the accelerator to make it go. Can't be sure. Needless to say, other vehicles got angry because they had to brake hard, they honked, rightfully so, when I did not speed up or get out of the way. Waved to say "my bad" to no avail. Totally embarrassing, although did not know that it was a vehicle issue. More importantly, very dangerous, and let's just say, I was pretty close to requiring a change of shorts.

That is the first time I have experienced any issue with this car (other than door lock sensors not responding...but likely user error), and it was a doozy.

Haven't had an opportunity yet, but going to try replicating the scenario to see if it will do it again, in absence of cars accelerating toward me.

Don't worry. Genesis is committing suicide when they decided to go fully electric by 2025. They obviously have no concept of their customer base. I've owned a Stinger and two G70s (one is only a month old) and never had any problems until the acceleration lag I've been experiencing the past couple of weeks. I truly think it's a quality control and skimping on parts since COVID was released on the world.

Yup, sounds familiar. It always happened to me in traffic circles, usually going just 30 KMH and then hitting the gas and nothing happens. If you are on the gas mileage screen, you can see consumption go way up but the RPM doesn't increase.

It was really bad on the highway. Going 100 KMH (60 MPH), I could floor it...it would shift down, rev almost to the redline but wouldn't speed up or shift up...just stayed the same speed with the engine racing. That's when I said I will not drive it anymore...it is dangerous. They gave me a loaner, diagnosed the problem and got a new part 5 weeks later. Been fine since then.

I think I have had that happen once on highway as well now that you mention it. Well, almost due for my 1 yr service so will tell them about the issue and how yours was resolved.

Thx.

If they need to refer to another dealership, it's Genesis South Edmonton...my tag is my name. Good luck.

They’ve managed to find a fault code in relation to the electric water pump. Apparently the fault is non-latching and can self reset so can be tricky to diagnose. The fault causes the car go into a limp mode.

Parts to be ordered and ETA up to 6 weeks depending on availability.

Hmm, when they replaced the throttle body, they also replaced a leaking water pump.
