1997 Cadillac Catera Problems

What owners report

Owners of this model year report a wide spread of problems, with engine and cooling complaints dominating: coolant loss, overheating and failures of the belt tensioner, timing belt or water pump are recurring themes, often with the vehicle losing power on the road. Electrical troubles (no-start conditions, ignition switch and lock problems, door locks, dash wiring) and premature front-tire wear are the next most common. Many reports come in at moderate mileage, in the 40,000-90,000 mile range.

   Engine cooling

   Serpentine belt tensioner / timing belt failure

   • 39 complaints (24%)
   • median 80,511 mi at 7.7 yrs old (5 state mileage, few)
   • owner-quoted repair $6,363 (median of 10 quotes)
   • filed 1998–2009

   Owners describe the belt tensioner, idler pulley or timing belt letting go while driving, sometimes with a warning noise beforehand. Complaints say the engine then lost power or shut down and the vehicle had to be towed; in several cases dealers reported bent valves or internal engine damage afterward. Some owners mention a campaign or recall letter about the tensioner and difficulty getting repair records or coverage. Reported at highway speeds and at mileages from roughly 60,000 up past 100,000 miles.

   What to check: Ask for records showing the timing belt, tensioner and idler pulley were replaced, and listen for belt or pulley noise on a cold start. Service bulletins describe tensioner and water pump work, so confirm what was actually done.

   “I took my car in for the 75,000 mile check up and advised dealership I was hearing a noise. They advised car was fine. I paid $200 for the work. The next week the car was making the same noise, I took it back to the same dealership and this time they said it was the belt tensioner. I paid $280 to have that fixed. The very next week, while driving on the hov lane to take my baby to daycare, the car stopped accelerating and went dead while I was going 65mph. The car was inoperable and towed to the dealership. …”

   NHTSA complaint #754780, filed 2001-11

   “While driving about 65 MPH on the highway and without warning the vehicle shut down due to a belt which held the pulley into the engine, melting. The driver was able to pull over to the shoulder of the road. The vehicle was towed to the dealer for analysis. The mechanic discovered what the problem was and informed the consumer the part was on recall.”

   • 1 mention a crash, fire or injury
   • owner-quoted repair $5,413 (median of 8 quotes)
   • filed 1998–2009

   Complaints describe coolant disappearing with no obvious puddle, the low-coolant or radiator light coming on, steam or smoke from under the hood and overheating while driving.

   “This car was taken to dealer on 2/8/04 for recall 2041, 1037. Two days after picking up the car, the low coolant light came on my way home from work. My husband checked the coolant reservoir and it was over one inch below full, he also checked the driveway for any antifreeze and checked where you put oil in the engine but could not find any signs of external leaks, but a white milky substance under the oil cap. The car has been sitting in my driveway since. I emailed GM about this. This was their response! …”

   Electrical system

   No-start, stalling and ignition switch problems

   • 30 complaints (18%)
   • median 80,511 mi at 7.3 yrs old (5 state mileage, few)
   • filed 1998–2005

   Owners report the car failing to start with good cranking power, stalling or cutting out while driving, and the ignition switch or lock sticking so the key will not turn. Dealers replaced ignition switches, starters, batteries, alternators and in some cases the engine control module, with complaints that the same fault came back or that no cause was found. Reported across a wide mileage range, from low mileage up to around 88,000 miles.

   2 related service bulletins

   What to check: Start the car from cold and try it several times, and check that the key turns freely in the lock. Ask for any invoices for ignition switch, starter or control module replacement.

   “My vehicle is a 97 Cadillac Catera and has had the starter replaced and still will not start. Two car lots have had the vehicle at the Cadillac dealership now and they are giving me the run around they say that its the mass airflow sensor but still have not replaced it yet I'm wondering why Cadillac has not notified people of this problem when I'm being told that it is a common problem with cateras of them not starting.”

   NHTSA complaint #10130643, filed 2005-07, 88,000 miles

   “Vehicle failed to start even with ample cranking power. Towed to Cadillac dealership. Problem diagnosed as onboard computer containing emissions control unit. I was advised by my extended svc warranty company that because ecu was involved, repair should be covered under mandatory 8/80 federal emissions warranty required of manufacturers by the fed. Clean air act. (veh. Is six years old and has 61,000 miles).GM takes the position that repair is not covered under the fed emissions warranty but will not provide me a written explanation. …”

   Suspension

   Premature front tire wear and alignment

   • 23 complaints (14%)
   • median 75,400 mi at 7.5 yrs old (3 state mileage, few)
   • filed 1997–2014

   Owners describe tires wearing unevenly or wearing out very quickly, with cupping, flat spots, vibration and the car pulling to one side. Several say repeated alignments did not hold, and a few report that front-end parts such as tie rod ends or a bent front-end component were replaced. Reported at a range of mileages, often noticed within the first few years of ownership.

   What to check: Look at the inner and outer edges of the front tires for uneven wear and check for vibration at highway speed. Ask for recent alignment printouts and whether front-end components were replaced.

   “While driving steering wheel had to be steered to the left to avoid vehicle from going automatically to the right. Took vehicle to the dealer, and dealer determined that something in the front end was bent.”

   NHTSA complaint #10065044, filed 2004-03, 75,400 miles

   “Excessive wear of tires due to poor alignment from manufacturer. Manufacturer is aware of problem , nothing is being done to correct it. Steel belts were showing through, and could cause greater damage. The manufacturer's service representative acknowledges that the vehicle had engineering design flaw.”

   Exterior lighting

   Headlight aim adjusters break

   • 8 complaints (5%)
   • median 35,066 mi at 7.2 yrs old (4 state mileage, few)
   • filed 2000–2004

   Complaints describe the headlight aiming mechanism breaking so the lamps point at the ground and cannot be readjusted. Owners report the only remedy offered was replacing the whole headlight assembly, which they describe as expensive, and some note the replacement units look different from the originals. Reported from about 25,000 miles up, often on cars several years old.

   1 related service bulletin

   What to check: At night, check that both headlights light the road ahead at a sensible height and that the adjusters move when turned. Ask whether either headlight assembly has been replaced.

   2 excerpts from owner complaints in NHTSA records

   “The 97-99 Cadillac Catera in my opionion has a bad headlight design. My 6 year old car has broken headlight adjustors. This makes it basically impossible to aim (adjust) the headlights. Replacment headlights are available from the parts department, but the cost about $340 per headlight. This is an excessive cost to consumer to repair. My understanding is this is a very common failure on this car. Headlight assemblies should last the lifetime of the vehicle, not just several years. …”

   NHTSA complaint #10040925, filed 2003-09

   “The consumer stated the headlight assembly deteriorated, which caused a misalignment of the headlights. Dealer had been contacted. Cadillac refused to pay for the cost of each headlight replacement. The consumer felt this should be a recall.”

   NHTSA complaint #10027337, filed 2003-09, 46,000 miles

Buying note. Because cooling and belt-drive failures are the most frequent theme, a pre-purchase inspection should focus on the timing belt, tensioner, water pump and coolant system records, and on a cold-start check of the electrics. Tire wear and headlight aim are easy to verify in person and worth factoring into the price.
