Buick - LeSabre :: 2002 - Lurching Forward And Slowing Down Repeatedly On Freeway - Possible Power Surge?
Jul 19, 2014
My 2002 Buick Lesabre has about 160,000 miles on it I keep up with maintenance regular oil changes and what not. Today when I am driving to work and right as I get on the freeway my car starts lurching forward and slowing down repeatedly so I pull over turn the car off look under the hood everything looks normal to me. I wait a bit start the car up and the lights on my panel go from the dimmest they can be to blinding bright and I could not adjust the brightness at all. Any way the car drove fine the rest of the way but the lights were bright as can be the whole way there. What could be causing this? Bad battery?

2002 Santa Fe has been misfiring for about a month...yesterday it got worse...When it's running hot and stopped at intersection it lurches forward.. It stalled when backing up after being parked. Mechanic did diagnostic test and it showed zero...He changed 2 wires to spark plugs..Spark plugs have only 20,000 miles and SUV has 68,000 miles.

On two occasions, about 18 months apart, my Hyundai Sonata started lurching down the freeway, losing power at approx. 3000rpm and regaining it at about 2500rpm. (I was traveling about 70mph.) The first time I was hauled home and the second time i tried to maintain speed and limped home 40 miles on Hwy 80W outside of Sacramento, CA. AAA mechanics reset computer both times and the first time replaced gasket on accelerator. The second time they reset computer but could not find what caused computer to malfunction.

I have a 2002 Buick LeSabre. Back information is this. the car has had a coolant leak for years, very slow though. Last night while working (I drive for a living) the thermostat climbed up to hot and then immediately went back down to the middle range where it normally goes, so I thought I was fine. It then climbed back up and staled out. It started again nearly immediately and I made it back to my work. About 30 minutes later I began to drive home. The temperature gauge started to climb up again, and then immediately went back to normal running temperature. I kept an eye on it.
About 2 minutes later it shut off completely. I had dash lights, head lights, and emergency flashers. Trying to restart it killed my battery and I had it towed home. This morning I put water in it (it was a gallon low even though I had filled it three days prior). I got a jump start but the car wouldn't start. It cranked and cranked but would not start. I did notice a leak of water from near the bottom of the engine. I am curious as to what the problem may be and why it is not starting now.

we just replaced the intake manifold and also put on new spark plug wires and plugs. now the engine is missing but only after it warms up. i double checked all the wires and connections and they looked good. is there something obvious that i should look at since it is still doing it?

Buick LeSabre 2002.. Several months ago, several electric items in my car failed... all at once. For the cig lighter especially, I looked through both fuseboxes (front and back) for any fuse that looked like it might be responsible for that circuit. I was checking the abbreviations on the fusebox diagrams and wasn't able to find a busted fuse.
However, with several things going wrong at once, I wonder if it was some other kind of fuse or relay. I don't have the equipment to check relays, thought I found how to do it on YouTube. What might be causing them all to stop working at once.

I have a 02 Buick Lesabre. The door locks and windows won't roll up or down anymore. I have checked and replaced the 30 amp fuse for power windows and also checked and replaced the window door switch for the drivers side and still nothing works. What else could it be?

Having problems setting driver comfort controls after replacing the battery. Does the car have to go thru a relearn process before all will come back to normal?
Used to be able to keep A/C set on auto. Now the A/C and fan motor won't come on unless you turn A/C to Off and then hit the AUTO button.

Symptom, loss of horse power (from a stop and going uphill), surge or lunge forward when accelerating (misfire?), rough idle (occasional knock). Maintenance, regularly change all filters and fluids, recently had the m.a.f cleaned and changed air filter, spark plugs and wires, oil.
There have been times in the past year or so when the car would crank but not start. Especially when the car was hot. Wait a couple minutes and it would start. Also a couple of times the car would shake fairly hard when started, get up to speed and it was fine.
I have had people tell me anything from a clogged catalytic converter to bad fuel injectors or fuel pump.
Scanned the car last week. No codes showed up. Never had a Check Engine Light.
I forgot to mention that every once and a while the car will jerk when accelerating. I have a coworker who said his truck started to jerk forward and later would not start at all. Our mechanic said it was the fuel pump. I I will see what that does for him.

My 2001 Buick Lesabre 3.8 loses power at highway speeds, sets a PO101 code (MAF sensor). I have replaced the MAF sensor 3 times, as well as the coolant temperature sensor, the crank position sensor, the throttle position sensor, the MAP sensor, the intake manifold gaskets (upper and lower) , the pcv valve, the egr valve, the Idle air control sensor. After cruising at highway speed for about 3 miles the car still loses power for about 20 seconds then gradually regains power only to repeat the fault again 3 or 4 miles down the road.
Otherwise the car has plenty of power quickly achieving 100+ mph going though the gears smoothly and normally. I have inspected the intake plenum and vacuum hoses for leaks and have found none, all in very good condition. The car ha 122,000 miles on it and has been well cared for, very clean under the hood with no leaks. I did reduce the egr chimney size to 3/8" while replacing the intake gaskets and that reduced the symptoms somewhat, i.e., the car only loses about 15 mph instead of dropping to about 25 mph before recovering.

I seem to lose power steering pressure when I hold the wheel in a turn. It is only temporary as it cycles until I release the turn. I happens turning in both directions and a any speed. I have replaced the struts and strut mounts and have rotated the tires. The power steering fluid quantity is good with no leaks.1995 Buick Lesabre.

This is an issue when I brake over a small bump or pothole. It lurches forward and I feel like I have lost control of the brakes and we are about to crash into the car in front of me. Seems like this is an issue with other Prius years but I thought this was fixed with the v.

I have a 2007 Passat 2.0T wagon. I got gas this am, and on my 30 minute drive to work all was fine until I got into traffic or came to a stop sign. While at the stop sign the car started to lurch forward or even seemed to be up and down. The idle was fine, completely constant. It was like the car was hopping or wanting to push forward. It did not happen in reverse or neutral and the car was fine while driving. What this could be?

My 2013 goes 7mph with the foot off the gas. Why is it doing this and is there any way to correct this?
Is this normal? I have to keep my foot jammed on the brake to stop the car from lurching forward.

I've been told by my dealer that the 6-speed transmission in our rigs is known to shift roughly. They have therefore pronounced my truck healthy. However, I don't think I believe it. I've never seen a vehicle that lurched forward on upshifts under moderate acceleration. It behaves if I punch it. It behaves if I accelerate like my granny. Anything in between and I get a fairly violent jump at each shift point. At times, in stop-and-go traffice, I have thought the truck would jump into the car ahead of me. This behavior seems to be unrelated to which transmission mode I'm in. D, S, and Tip all do it. I love the motor in this thing, but I'm starting to hate the tranny. What should I tell the dealer to look for on the truck that might be causing this? The truck is going in next week to replace a fog light with condensation, so I'm hoping to get them to look at it then.

So this doesn't begin until I put it into a forward gear, but after about 30 sec of smooth running, I will get a sudden momentary loss of power, then a surge, which repeats and intensifies as the van lurches forward until the engine finally stalls. Throwing it into N in the middle doesn't work. Babying the gas had no effect. It happened both at higher(2.5-3K) revs and at lower (.8-1.5k).
After killing the battery starting and restarting it just to keep it moving, I had it jumped, at which point I sat with it in P for 20 min to charge the battery and in all that time, it ran fine. I'd love to hear some possible diagnoses. Don't know if I should have it towed from where it's sitting, or try to drive it to the shop, or if it's something I can repair myself (think 1-star difficulty).

My car (1994 TBird, LX) has an intermittent problem where the rpm's surge while I'm cruising down the freeway. I've noticed that it happens more often on an incline, and it also happens more during rush hour when I have to frequently slow down and the accelerate again.
If I had to guess, I think it's the TCC Solenoid that's the issue. Would replacing this likely solve the problem? Or would I be better served having my mechanic unplug it? My car is giving error codes to replace the camshaft position sensor (related?), and while important, I need to address the rpm issue first as it's getting progressively worse. Tranny fluid is clean, although I've only owned the car for 2 months so I don't know when it was last replaced.
I can't afford a huge repair, but I have a certified mechanic who's always done right by me, but he's not the best at diagnosis. I'd feel better if I could whittle down the issues and then just tell him what to fix.

Earlier this winter and last year, the forum had discussed the occasional fast idle in the 3.6L. Symptoms include the engine idling at 950-1000 RPM and the car feeling like it wants to surge forward. I had the problem twice during heavy snowstorms in February, but nothing really since...until this past week.
The weather here in Chicago has been in the early 90s and I've had the AC cranked. At the same point, I've had the fast idle event occur at least 5-6 times in the past week. Almost every time it has occurred while moving in very heavy traffic. Have others seen something similar in very hot weather?

I have a Gen III Prius 2010 with about 50k on it. I've noticed over the past month that when the ICE shuts down at a stoplight, the car will surge forward a bit. If my foot isn't on the brake really hard, it will translate to the car actually moving forward until the ICE is totally off. If my foot is on the brake hard, you can feel it push against the brakes, and then the car settles back in place. It doesn't happen every time, so it still takes me by surprise.

I don't know if this is related, but my car has not shifted as well as it did before I gave it my oil change. The car only has 3K miles, new Hyundai oil filter, and Mobil 1 Synthetic 5w-20.
It's not a major dip in performance, but enough for me to know its different. One example is when I come to a stop, the car seems to surge forward a little bit. Another is that is shifts hard from time to time when I give it gas.
Going uphill, it just doesn't have the power like it did. Also, it feels that it's not in the right gear..like 5th or 6th gear. It's hard to describe the symptoms. The weird part is that the MPG is the higher than normal.

I had the tranny/transfer case flash done sometime ago, which yielded smoother driving in "D" mode. However, I noticed that when braking in "S" mode, the downshifts actually cause the car to surge forward strongly. It's disconcerting enough that I now avoid driving in "S" mode unless I need to merge into traffic quickly; even then, I prefer shifting manually instead.
