2004 Buick Lesabre Problems

What owners report

Owners of this model year most often report instrument cluster failures — speedometers, fuel gauges and other gauges going dead, sticking or reading wildly wrong — usually starting in the 40,000–100,000 mile range and often intermittent. A second recurring theme is the dashboard pad lifting and separating along the driver's side, with owners worried about airbag deployment, along with occasional hard transmission shifts and electrical/starting quirks.

   Electrical system

   Instrument cluster gauges fail or read wrong

   • 60 complaints (37%)
   • median 60,000 mi at 6.6 yrs old (51 state mileage)
   • owner-quoted repair $400 (median of 15 quotes)
   • filed 2005–2022

   Complaints describe the speedometer, fuel gauge, tachometer and temperature gauge either stopping entirely, sticking at zero or pegging past full scale, sometimes showing double the actual speed or reading 120 while parked. The failure is usually intermittent and can reset briefly when the car is restarted or the instrument panel fuse is pulled. Owners who took the car to a dealer or independent shop were commonly told the whole cluster needed replacement, with quotes in the several-hundred-dollar range; some said the part was no longer produced or that warranty did not cover it. Several complaints note that the odometer kept working while the other gauges did not. Spread widely — reports begin as early as roughly 40,000 miles and continue past 150,000 miles; often intermittent and sometimes worse in cold or damp conditions.

   What to check: With the key on and engine running, watch every gauge through a full sweep and confirm the speedometer returns to zero at rest; a working odometer with dead gauges is a common pattern. Ask whether the cluster or stepper motors have already been replaced, and get the quote for a rebuilt cluster before buying.

   2 excerpts from owner complaints in NHTSA records

   “While driving at approximately 45 MPH, the speedometer shows 90. Sometimes stays on 0 no matter what speed I am driving. I spoke to a dealer and he indicated that it may be the gauge cluster and would cost about $400 to $500. With all the complaints on this situation, why is there not a recall.”

   NHTSA complaint #10604952, filed 2014-06, 62,496 miles

   “While traveling on vacation at different elevations above sea level. The speedometer was either showing a speed faster or slower than the actual speed (checked w/ a GPS device). It first appeared when driving downhill on a curvy road. The speedometer was showing 20-25, but we were actually going about 65. We were able to control the speed and slow down. Another day, the speedometer was showing 120 MPH and we were driving 70.”

   Body and structure

   Dashboard pad lifting and separating from the dash

   • 23 complaints (14%)
   • median 61,950 mi at 8.7 yrs old (16 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2008–2017

   Owners describe the padded dashboard cover buckling upward, lifting away from the cowl and pulling back from the windshield, often starting on the driver's side and spreading toward the passenger side. Some report the pad moving back and forth while driving, or the dash fracturing and exposing underlying material. Several complaints raise concern about the cover interfering with airbag deployment on the passenger side. Dealers reportedly said they were unaware of the condition or that it was outside warranty, and the vehicles were typically not repaired. Mostly reported between about 20,000 and 120,000 miles, and often noticed on vehicles kept outdoors or in hot climates.

   What to check: Run a hand along the top of the dash near the windshield and look for a raised seam, bubbling or a gap at the cowl on both sides; press gently to see whether the pad is still bonded. Check that the passenger-side airbag cover sits flush.

   “Dash board pad popped up above the gage panel approx. 14 was reported to Buick service center and was told no warranty. This vehicle is garage kept except when in transit. I have owned quite a number of general motors vehicles and never witnessed this problem. I am 73 years of age. My other car is a toyota in 2015 I will buy my third prius. My brothers are all toyota owners. Never another american car.”

   NHTSA complaint #10548915, filed 2013-10, 45,000 miles

   “Dash has started to buckle up in front of driver side of the vehicle. This is a safety issue as it impacts the visibility of the driver and might impair (or cause) the improper deployment of the airbag.”

   Air bags

   Airbag warning light or deployment concerns

   • 30 complaints (19%)
   • median 60,000 mi at 7.8 yrs old (23 state mileage)
   • 8 mention a crash, fire or injury
   • filed 2004–2017

   Owners report the airbag service light coming on and going off at random, in one case after the horn was pressed. Others describe frontal airbags not deploying in a collision, or deploying in a low-speed bumper contact, and some tie their worry to the dash pad lifting over the passenger airbag. In several complaints the vehicle was not repaired and the manufacturer or dealer offered no assistance. Scattered across the range, from very low mileage up to about 115,000 miles, with no clear pattern.

   What to check: Turn the key to run and confirm the airbag light comes on and then goes out; a light that stays on or flickers points to a circuit fault. Ask whether the car has been in a collision and have any stored airbag codes read.

   2 excerpts from owner complaints in NHTSA records

   “While driving, both frontal air bags deployed when tapping the bumper in front at 5 MPH. This caused the driver to sustain minor injuries. The vehicle was towed to a garage. The dashboard collapsed and the windshield shattered in two places and caused abrasions on both of the consumer's wife's arms due to the deployment.”

   NHTSA complaint #10081723, filed 2004-07, 8,077 miles

   “Dashboard cover started lifting and pulling out from under windshield cowling about june 2012 and is traveling across to the passenger side where there is an airbag. I am now concerned that the lifting and creasing in front of the driver is a safety distraction and that if it continues to the passenger airbag that airbag may get set off unexpectedly, another safety hazard. It is definitely a manufacturer's defect and there are hundreds, if not thousands, of complaints of this on the internet. …”

   Electrical system

   Stalling, no-start and random power loss

   • 14 complaints (9%)
   • median 67,000 mi at 7.0 yrs old (11 state mileage)
   • filed 2004–2021

   Complaints describe the engine shutting off while driving or while turning over a bump, followed by a crank with no start, and some note the security or theft-deterrent system was suspected. Owners report the anti-theft module replaced and keys reprogrammed, crankshaft sensor and ignition module replacement, and batteries replaced repeatedly without a lasting fix. Several say the car loses all power if left parked for more than a day. Reported from roughly 15,000 to 131,000 miles, often intermittent and hard for shops to reproduce.

   2 related service bulletins

   What to check: Ask whether the battery has been replaced more than once and whether the anti-theft module or crank sensor has been changed. Check for a battery drain by leaving the car parked a day or two before purchase, and have the charging system and grounds checked.

   “This car loses all power if it sits in the driveway for more than 24 hours. We have replaced the battery twice in the past year and the dealer states they can find nothing wrong with the electrical system. We have had it towed to the dealership twice because aaa can't start it with their portable chargers. We have purchased our own charger to use on it each time it dies - which it does if you do not drive it within 24 hours of your last start.”

   NHTSA complaint #10178217, filed 2007-01, 38,000 miles

   “My 2004 Buick Lesabre keeps losing power while I am driving. This is the 4th incident in 2 months! The vehicle dies and the power steering locks. This is a dangerous situation as I was on hwy 190 and there is major work being done. I was driving over a bridge and their are barriers on both sides of the highway. Each time the incident occurs I get a crank but no start. My vehicle is then towed to a mechanic and I've been told that the crank shaft sensor and ignition module are bad. …”

   Transmission and drivetrain

   Hard or harsh transmission shifts

   Mentioned in 4 of 60 sampled complaints

   Complaints describe a pronounced jolt or jerk when accelerating from a stop or when slowing to a stop, sometimes described as the transmission going into a high-pressure mode. Owners who researched the problem point to the pressure control solenoid and shift solenoids in the automatic transaxle, and report that mechanics replaced the solenoid with varying results. Several say dealers did not offer assistance and that the concern was treated as normal or out of warranty. Reported mostly between about 75,000 and 145,000 miles, with symptoms appearing during normal city and highway driving.

   4 related service bulletins

   What to check: Drive the car from a cold start and feel for a clunk or surge on the 1-2 shift and when coming to a stop. Ask for transmission service records and whether the pressure control solenoid has been replaced.

   “J & k mitchell casey, il.62420 purchased on 4/11/2014, 98,104 mileage. Headlamps go off at nite driving, very unnerving, fuel gage, haywire from the start, while driving, engine would accelerate when turning right. Swaying/suspension, when turning, driving down the road, reported this many times and taken into dealer..however, never taken care of. Only thing fixed was solenoid.”

   NHTSA complaint #10936638, filed 2016-12, 98,139 miles

   “Within the passed 2 months I have been experiencing hard shifts . Very pronounced jolt/jerk when accelerating after a full stop or decelerating to come to a stop. Just researched on this site and found many other consumers with 2004 Lesabre's experiencing same situation. Has to do with inferior pressure control solenoid and/or shift solenoids. Apparently GM has refused to recall and replace due to the cost. Can cause premature failure of transmission and they say they are under no obligation to make it right!!! …”

   NHTSA complaint #10846233, filed 2016-03, 75,000 miles

Buying note. On a car this age the instrument cluster and dash pad are the two things most worth inspecting closely, since both are common complaints and both are costly to put right. Drive it long enough to see the transmission shift from cold, watch the gauges for a full cycle, and ask for service records on the battery, sensors and cluster.
